DASDEC II Installation and Configuration
1 DASDEC II Hardware 1.1
Introduction
The DASDEC II is a 2U rack mounted unit built with the latest digital PC computer technology. It is an embedded PC
platform. The front of the DASDEC II, pictured below, provides a very simple face for a very sophisticated platform. The
DASDEC II exposes the PC motherboard connectors and single PCI slot in the rear of the unit.
Front panel of the DASDEC II
1.2
Front Panel
The front panel features a 2 x 20 character backlit LCD that indicates power-on and real-time device status. There are two
LEDs - one red, one green - to indicate specific types of status. A small grill provides space for audio from the internal
speaker. One push-button can initiate a simple weekly test.
1.2.1 LCD
The backlit green LCD shows real-time status of the DASDEC II. The LCD has numerous purposes indicating
system and/or encoding/decoding and active alert and button action status. Here is a list of information available
from the LCD.
 When the DASDEC II is powered on, the LCD lights up, indicating power-on state.
 When the DASDEC II begins to boot load system software, the LCD displays three phases of power up
disk check status, eventually moving on to display a busy booting indicator and the clock time. After all
system startup software is loaded, the LCD displays a startup message, eventually arriving at the ready
state where the first line displays DASDEC II: ON, followed by a crawling display showing the
programmed unit name, the software version number and the IP address. The second LCD line
continues to display the current clock time.
 If the system software is manually stopped or temporarily restarted due to an internal problem, the LCD
will display a Server Stopped message until the software restarts into a ready state.
 During decoding of an incoming alert, the LCD displays information about the source and the stage of the
decoding.
 While decoded, forwarded or originated alerts are active on the DASDEC II, the top line repeats,
displaying pertinent identification for each active alert.
 If the front panel button is pressed, the bottom row of the LCD will display information about the button
push action. When the button push is to start a Weekly test, the display instructs of the need to push the
button once more in order to confirm the issue of the Weekly Test. When the button push is to
acknowledge an unforwarded decoded active alert, the display briefly displays the acknowledgment.
 When a backup configuration is loaded or when the server software is restarted, the LCD will indicate
when the server is down or running again.
 During a software upgrade, the LCD display will progress through server down states and eventually will
display "Upgrading'. When the upgrade is finished, the LCD will progress back to the original ready
state.
4 Digital Alert Systems: DASDEC User Manual 1.2.2 Status LED
The DASDEC II's two LEDS are used for a variety of status indications, making it easy to see the state of certain
important system information.
System Status - Green LED
 When the DASDEC II is first powered on, the green LED is dark.
 When the booting process advances far enough, the green LED begins to blink.
 When the DASDEC II nears a ready state, the green LED blinks more rapidly. When the DASDEC II is
ready, the green LED light is on solid. A solid green LED indicates the DASDEC II is operational.
 If the green LED starts blinking, the DASDEC II server has become non-operational. This can happen
during software restart or upgrades.
Alert status - Red LED
 When the DASDEC II is first powered on, the red LEDs are dark.
 After the DASDEC II becomes operational, in a ready state, with the green LED solid, the red LED
indicates decoding, alert sending status, and unacknowledged, unforwarded active decoded alerts.
 If the red LED is blinking quickly, with pauses, the DASDEC II server is decoding an incoming alert. If the
red LED is solid, the DASDEC II is sending an EAS alert. If the red LED is blinking slowly and regularly,
an active alert has been decoded and has not been forwarded or acknowledged. Alerts are
acknowledged by pressing the front panel button or by pushing the Acknowledge button for the alert on
the Web browser. If the red LED is blinking quickly and regularly, an active alert is being held pending
GPI 1 input closure.
1.3
Back Panel
The back of the DASDEC II provides all of the connection ports. In addition to the standard PS/2 mouse and keyboard
and VGA monitor ports, the DASDEC II provides an RS-232 serial port (COM1), two RJ45 LAN ports, four USB ports,
main audio line in, out, and microphone jacks, optional auxiliary audio line in, out, and microphone jacks, radio antenna
jacks, GPIO, and a TV video out connector. The DASDEC II provides software support for the TV out as a licensed option.
The optional second audio sound card likely also has an unused MIDI interface port.

2 Setup: Hardware 2.1
Audio Wiring
Audio wiring on the DASDEC II has some flexibility due to the option of adding a second sound card and because of builtin software control. Here are a few rules:
 EAS decoder input uses the analog audio line inputs or internal radio receivers.
 Each available analog line input can be used for decoding audio provided from an external receiver or another
EAS encoder. The web interface must be used to set an audio device input source from internal radios to line
input. Line input is NOT available on the AES digital card.
 An audio line input supports two (2) EAS decoders. The left side of the input is decoded separately from the right
side. So two line inputs provide four (4) EAS decoders.
 EAS alerts are selectively played out of the analog and/or digital line output ports. Software is used to select which
audio ports are used during alert origination and forwarding.
NOTE: The standard balanced audio hardware disables the main audio line out mini-jack.
The Main analog audio output is instead routed out through the balanced audio output port. This output is
available on the screw terminal connector. The balanced audio hardware also features balanced stereo analog
audio input pass through for routing analog program audio through the DASDEC II. The inputs are also available
on the screw terminal connector. EAS alert play-out overrides the main audio output during the alert notification
(this is software configurable; the DASDEC II can be made to always override the input pass through source).
Audio pass through continues to operate when the DASDEC II is unpowered.
 The main or aux microphone inputs can be used to record EAS audio messages. The ALSA sound software
option is required for these recordings to be clearly audible. DASDEC IIs come equipped with both OSS and
ALSA sound system options. The option can be selected from the Web interface by the Admin user.
 AES Digital audio output is available as a hardware option. The AES option occupies one of the two PCI slots. It
provides both analog and digital audio output via two breakout cables. It also provides a separate output
monitoring analog mini-jack. The AES hardware option requires the ALSA sound system.
NOTE: Audio input and digital audio pass-through is NOT available with this hardware option.
See Section 1.5 later on in the manual.
For decoding, each side of the stereo input of any audio input can be selectively used as a single decoder source. In other
words, one stereo input supports two EAS decoders. A dual RCA to 3.5 mm jack input adapter can be used to connect
two separate mono input signals to a DASDEC II line input jack.
For alert encoding/origination, an audio cable is run from the main balanced audio output or from software selected 3.5
mm line output jack into your systems alert audio wiring. Only analog audio output is supported.
NOTE: The SPDIF digital audio output port is not used.
2.2
AES Digital Audio Wiring
The DASDEC II includes the capability for an AES digital audio output, and a Failsafe AES audio loop through. Refer to
the diagrams below for cabling of the AES audio inputs and outputs.
6 Digital Alert Systems: DASDEC User Manual Diagram for Digital Audio Wiring
2.3
Video Wiring
Video output from the DASDEC II is an optional feature. When enabled, an NTSC analog composite video signal is
available from the RCA jack. This will provide a full details page during alert forwarding and/or alert origination. The video
page display takes a few moments to initialize. It will be steady when the GPO Audio or Video Output Relay is closed. It
will also be held until at least the Audio or Video relay is opened.
2.4
General Purpose Input / Output (GPIO)
The DASDEC II comes standard with two General Purpose Output relays and two General Purpose Input contact
closures. These are located in the upper middle of the back panel via a screw terminal connector. See the picture for
wiring info.
GPIO Terminal Connector
For DASDEC II's licensed for Broadcast features, both GPO relay outputs are programmable and triggering can also be
filtered against specific alert FIPS and EAS codes. GPO 1 is limited to Audio and Video events while GPO 2 supports
many other types of EAS events.
For non-broadcast DASDEC IIs, GPO 1 is non-programmable and is used as an Audio On-Air relay, being closed for the
duration of the EAS alert audio envelope play-out during alert origination or forwarding. GPO relay 2 is still programmable,
but supports fewer options.
Digital Alert Systems: DASDEC User Manual
7
Examples of events that can trigger a GPO relay are EAS audio or NTSC video play-out of an alert, or when an alert has
been decoded but not forwarded, or when an alert is held or delayed pending a GPI action.
The DASDEC II comes with two General Purpose contact closure inputs. GPIO input 1 can be programmed to trigger
forwarding of an un-forwarded alert or hold/delay the play-out of an active alert. Depending on the DASDEC II option
licensing, GPIO input 2 can be programmed to a variety of actions, such as (1) issue a Required Weekly test; or (2) to
trigger origination of an alert header/attention signal, pausing for voice dub of the audio message, followed by trigger of
the EOM audio; or (3) review of audio portion of an active alert; or (4) active alert acknowledgment; or (5) re-enabling of
active alert forwarding capability; or (6) forwarding of a Monthly test with original audio.
See Chapter 4.11 Setup > GPIO: Setup General Purpose IO Options
2.4.1 Optional Expansion GPIO
The DASDEC II supports three different Networked GPIO hardware options. These modules provide a very
convenient and practical way of adding programmable relays and inputs to a DASDEC II system. The DASDEC
II supports the Titus Technology WR-300 module with four relays (the same hardware as the Monroe Electronics
rack mounted R190 Hub Controller), and the Control-by-Web Web-Relay Quad with four relays (the same
hardware as the Monroe Electronics rack mounted R190A Hub Controller) and Control-by-Web Web-Relay Dual
module with two relays and two low voltage driven inputs. Web Relay Dual inputs require applied 3 to 12 VDC
(some industrial models 11 to 28VDC).
See Chapter 4.10.5 Setup > Net Alerts > Net GPIO.

The DASDEC II is equipped with one RS232 serial port on the back panel. In addition, one USB connection can be used
with a USB/serial port expander to provide up to four (4) more RS232 serial ports. The USB port expander requires an
FDTI chipset for compatibility. Digital Alert Systems can provide compatible adapters.
The serial ports are used to connect to and drive a variety of video character generators and BetaBrite LED signs. The
DASDEC II supports a wide variety of serial protocols, including the most commonly used protocols in legacy EAS
equipment such as TFT Standard and Sage Generic.
For configuration of serial port protocols, see Chapter 4.7 Setup > Video/CG.
Each serial port has the same PC pin-out as described below.

3 DASCEC II Server Interface 3.1
Power Up, User Interface and Initial Setup
The DASDEC II uses a standard AC power cord. It uses a single power toggle switch to power on.
NOTE: Power is supplied to the unit electronics while the external cord is plugged and
supplied with power.
There are two other ways to wire a network connection in order to use a Web browser user interface on a remote host.
The DASDEC II can be connected directly to another computer's Ethernet port using a network crossover cable, or can be
connected to a hub or router using a standard network cable. Network cabling may be done at any time. The DASDEC II
is given a default static network address of 192.168.0.200.
No matter which way is used, the standard interface for configuring and controlling the DASDEC II is a browser based
Web interface.
NOTE: the DASDEC II must be fully booted before it can provide a network connection.
Once the DASDEC II is correctly wired; power up by pressing the power switch or rocker on the upper left corner of the
backside. The LCD screen will light up if power is applied. Allow the DASDEC II time to boot. The LCD screen and the
green system status LED will indicate when the DASDEC II is ready.
While the DASDEC II can operate with the KDE desktop enabled, the KDE desktop consumes much memory and extra
CPU speed. The provided KDE desktop applications are meant as conveniences and tools during DASDEC II
configuration. These should not be used indiscriminately during normal DASDEC II operation. Using applications from the
desktop during normal operation can interfere with the reliable performance of the decoder software.
3.1.1 Directly connecting a networked host computer
Once the DASDEC II is powered up, booted, and operational, it can be accessed via a Web browser from a
directly connected computer on the default DASDEC II network of 192.168.0.0.
Connect a CAT-5 network crossover cable, supplied with the unit, to the RJ45 port at the back of the DASDEC II
and to the RJ45 port of the network interface card (NIC) of a standalone PC or notebook computer. Configure the
standalone PC to use the static IP address 192.168.0.2 with a net mask of 255.255.0.0. After DASDEC II power
up and booting, it can be accessed via a Web browser on this host computer.
Now launch a Web browser application and direct the URL to http://192.168.0.200/. The DASDEC II will provide
a gateway page and quickly redirect to the DASDEC II login page. Follow the instructions in Chapter 3.2 Web
Server Login for logging into the DASDEC II using the Web login page. After login, the DASDEC II is ready to
use, although typically it will be desirable to reconfigure the network address. If the network address is changed,
subsequent logins need to use the new address in the http URL.
Follow the directions in Chapter 3 for general DASDEC II Decoder/Encoder setup via the Web browser
interface.
10 Digital Alert Systems: DASDEC User Manual 3.1.2 LAN connection with a networked host computer
Connect a standard CAT-5 network cable from the RJ45 port at the back of the DASDEC II into a routing hub or
other network switching device. You will likely need assistance from a network administrator to insure the
DASDEC II's default network address of 192.168.0.200 will be visible on the network, or will not clash with an
existing node (optionally, you will have to change the DASDEC II IP address using one of the methods described
above in section 3.1.1). Once the DASDEC II is powered up, booted, and operational, it can be accessed via a
Web browser from any remote computer on the LAN routed to see the address 192.168.0.200 (or whatever
address has already been used for the DASDEC II).
Follow the instructions in Chapter 3.2 Web Server Login for logging into the DASDEC II using the Web login
page. After login, the DASDEC II is ready to use, although typically it will be desirable to reconfigure the network
address. If the network address is changed, subsequent logins will need to use the new address in the http URL.
Follow the directions in Chapter 4 for general DASDEC II Decoder/Encoder setup via the Web browser interface.
3.2
Web Server Login
The DASDEC II features a built in Web Server that provides the user interface for all operations. This means the DASDEC
II can be operated over a LAN via any popular Web Browser. It also means that no special interface software or operating
system is required. When the DASDEC II is operated from a directly connected monitor, a built in Web browser is used
DASDEC II Web Browser Login Screen
To reach the DASDEC II Web interface from a browser, make sure the DASDEC II is on the same LAN as the browser
host and type http://<DASDEC II IP Address> (for example, http://192.168.0.200). If secure access has been configured,
you must use https and a browser that supports 128-bit SSL encryption. When the DASDEC II successfully connects for a
Web session, it presents the following page in the Web browser.
Type Admin as the default user name
Type dasdec as the default password
Click the
button. With the correct user name and password, the DASDEC II will login. If the user or password is
incorrect, the DASDEC II will display a message indicating the problem. If the DASDEC II is left unattended for 10 minutes
the idle logged in account will automatically logout. A message indicating session timeout will be displayed on the login
screen. Multiple login sessions are allowed at the same time.
At the first login, DASDEC II will show the main tabbed page Setup with the radio button page Server in your web
browser (Setup > Server page). Subsequent logins will start at the last page displayed prior to logout.

3.3
DASDEC II Page Organization, Web Interface and Navigation
Each DASDEC II page has three sections:
TOP: the standard page header
MIDDLE: the interactive page
BOTTOM: a row of standard links
3.3.1 DASDEC II Page Header
The top section of every screen, or web page, has a standard header area with the following information:
 DASDEC II Server Name
 Four top level tabbed menu selections: Encoder, Decoder, Server, and Setup. A DASDEC II licensed as
both decoder and encoder displays four tabbed pages, including Encoder. A DASDEC II licensed as
decoder-only has three tabbed pages in the header; the Encoder page tab does not display.
 A set of radio buttons on the selected tabbed menu.

and
buttons.
NOTE: The DASDEC II does not rely on the browser's back and reload commands located in
the browser main menu. DASDEC II has its own Back and Refresh buttons. See Chapter
3.3.4.1 Back and Refresh Buttons.
 "User IP address in dot notation" <=>. The current user's host computer IP address is displayed here.
 User: Name (and optionally the number of times this user is currently logged on and the total number of
active user sessions if other users are logged on),
 Server time.

button
 Page Title (Page Name).
 Software Version. The DASDEC II software version number is located in the box on the top right side of the
page. The software version indicator provides a quick hyperlink to the Server Help page (Chapter 7.1
Server > Help: Server Help).
Standard DASDEC II Web Interface Page Header Display
3.3.2 Interactive DASDEC II Page
Below the standard page header is the interactive section of the DASDEC II page. This manual discusses each
section in detail.
3.3.3 Standard Links at Bottom of Page
At the bottom of each DASDEC II web page is a row of standard links. The links are:
12 Digital Alert Systems: DASDEC User Manual Back to the previous DASDEC II page
Refresh or reload the current page
Current Status to the DASDEC II Server > Status > Main page
OpLog to the DASDEC II Server > Logs > Operation Log page
Web Session Log to the DASDEC II Server > Logs > Web Session Log
3.3.4 Web Interface and Navigation
The DASDEC II uses a Web interface to setup, control, view status, and monitor all activity. Common web
interface commands are used. These include selecting radio buttons, toggle boxes or check boxes, entering text
in fields, pull-down menus and following active links. Commands can be entered with a mouse or the keyboard.
The DASDEC II has three navigation levels. The first level is one of the three or four tabbed menus at the top
of the header: Encoder, Decoder, Server, or Setup. The second level is one of the selected radio buttons under
the tabbed menu. The page selected will show a darkened radio button. Most pages selected with a radio button
have a third level of navigation, which is a series of tabbed sub-pages. Some pages selected with a radio button
do not have multiple pages with sub-tabs.
To navigate, select one of the tabbed menus at the top. Then select a radio button. Then, if a level of sub-tabbed
pages is displayed, choose the page desired. When moving between top level tabbed menus, such as from
Setup to Server and Back to Setup, the last selected location is remembered.
3.3.4.1 Back and Refresh Buttons
IMPORTANT! In general, DO NOT use the back button or the Refresh/Reload buttons on your browser.
Instead, ALWAYS use the DASDEC II
and
buttons. These are conveniently located in
both the standard header at the top of each DASDEC II page and in the row of links at the bottom of
each DASDEC II page.
Because the DASDEC II is a password protected Web interface, use the DASDEC II
and
buttons when you want to go back one screen or reload the current page to current values. Although
using the browser's back or refresh buttons might appear to work, the DASDEC II page displayed as a
result may have misleading, out-of-date server state information. Also, in some cases, this can result in
unintended actions being performed.
3.3.5 How to Make Changes and Update
This manual informs how to make changes on each web page. Changes are typically made with toggle or check
boxes, selection boxes, buttons and text entry fields.
Toggle boxes are labeled as to the name of the feature the box controls. The feature is either "Enabled" or
"Disabled". When the feature is "Enabled", a brief description of the feature usually follows, and the web page
instructs the user to click to disable the feature if it is not wanted. When the feature is "Disabled", the web page
instructs the user to click to enable the feature.
Many pages have an
button, typically at the bottom of the screen. These pages allow users to
cancel changes before they are accepted.
Digital Alert Systems: DASDEC User Manual

3.3.5.1 Pages with an Accept Changes Button
On pages with an
button, you must use the button to submit changes. Clicking on
the Accept Changes button updates the page information. If you exit the page without clicking on it, any
changes made are lost. When you return to the page, the page will still have the original settings.
On pages with an Accept Changes button, there will also be a
button. Use this button
when you have made changes to the page, have not clicked the Accept Changes button, and want to
return all settings to the original settings.
3.3.5.2 Pages without an Accept Changes Button
Pages without an
button make changes immediately through automatic page
submission. Changes made to check boxes, selection boxes, and by clicking buttons are immediate; the
page updates instantly. Pages with options that must change rapidly to be useful are the ones featuring
immediate updates. For example, changes on the Setup > Audio and Setup > Decoder > Forwarding
pages are immediate.
For text entry fields, generally you type the change in the field and then click the mouse anywhere on
the page, outside the text field box. The page updates immediately. (In this manual, the instructions for
text entry fields say, "Click page to change and update.") Some browsers also accept text entry
changes when you press the Enter key on your keyboard.
14 Digital Alert Systems: DASDEC User Manual 4 Setup: Web Interface One of the four top level tabbed menus is Setup. The Setup pages present the DASDEC II server configuration suboptions as a set of "radio buttons'. Only one radio button can be selected at a time. In left to right order the buttons are:
At the first login, before the DASDEC II can be used, the server must be set up and pre-configured. The recommended
order is to first set up the Server, then Network, Time, Users, Email, Audio, Video/CG, Decoder, Encoder, Net Alerts,
GPIO, Printer and Alert Storage. The subsequent manual sections are presented in this order. Each one reviews
information on the web page and provides additional information.
You may wish to review Chapter 4.3 DASDEC II Page Organization, Web Interface and Navigation; Chapter 3.3.4 Web
Interface and Navigation, and Chapter 3.3.4.1 Back and Refresh Buttons. For pages with an

Setup > Server: Setup Server
Before the DASDEC II can be used, the server must be pre-configured. Go to Setup > Server. There are three tabbed
sub-pages on the Setup > Server page. Only one of these, the Server Main/License page, needs to be reviewed during
initial configuration. The other two pages, Configuration Mgmt and Upgrade, support making and installing backups of the
Server Configuration and Server Software Upgrade. The three sections that follow review all three sub-pages under
Setup > Server.
4.1.1 Main/License: Server Name & License Key Configuration
Use this page to set the Web Interface name, enable licensed features and restart the server. There are two
main sections on this page: DASDEC -1EN Platform ID and License Key Configuration. The first task is to check
the License Key configuration. The core DASDEC software will only run if it has been enabled using a Master
license key. Most DASDECs are delivered pre-configured in the factory, so this task already may be complete.
NOTE: To restart the DASDEC II server software, click the
button at bottom of this
page. This is used during License Key configuration. It can also be used at any time the DASDEC II
appears to be functioning incorrectly. A confirmation page is displayed before the restart is actually
run. All logged-on users will be forced out of the system and will be required to log back in. Alert
decoding will be temporarily paused during the restart. This is not a system reboot, but nonetheless:
USE the Restart Server OPTION WITH CARE!
Reboot Server?: This option is a full system reboot. The unit will power down and go through the entire boot
process when it starts back up automatically.
Power Off Server?: This option powers down the DASDEC.

4.1.2 Configuration Management: Server Configuration Management
The interface on this page is used to manage configuration backup files. You can create a copy of the current
configuration of DASDEC II settings and review previously saved configuration files. Each configuration backup
is stored in an encrypted ZIP file. The file contains all settings selected in the Setup process. The backup
configuration file does not save Network setup, the email server name, user accounts, and license keys. As of
release 1.8-0, sound level settings are stored when a configuration backup file is created and are optionally
restorable. Configuration files made prior to 1.8-0 will load but do not contain audio level information and cannot
be used to set audio levels.
A recent backup configuration file is HIGHLY RECOMMENDED for a number of reasons. Backup configuration
files serve as a safety precaution. They provide a way to restore your DASDEC II settings in case of catastrophic
disk failure, or in the case of an upgrade error, or to restore the state of former DASDEC II settings when
experimenting with new settings. The backup allows you to easily and quickly return to the previous settings if a
serious configuration mistake is made. The backup configuration file can also be downloaded to another
computer for offline saving. Later, the backup configuration can be uploaded and reinstalled. The same
configuration file can be used to configure another DASDEC II EAS server.
When the DASDEC II is being configured for the first time, and before a backup configuration file is made, the
page states, "There are no backup configuration files yet." REMEMBER to return to this page to create a
20 Digital Alert Systems: DASDEC User Manual backup configuration file after you have completed setting up the DASDEC II or after you make
significant changes.
Creating the First Backup Configuration File: Click the
button to create the first backup
configuration file. After the first backup file is made, a pull-down list with the new file appears. All other standard
configuration management options appear as well.
"No previous configuration yet”: This message is displayed before any backup configuration files have been
installed. A previous configuration file is created automatically whenever a backup configuration file is installed.
When a previous configuration exists, the date of the file is presented along with a button for reinstalling this
configuration. The previous configuration backup allows you to easily and quickly return to the previous settings
before installation of a backup configuration.
Server Configuration File Management with Backup Files
The screen shot of this page shows a DASDEC II with both a current and previous backup configuration files.
There are three main areas to review on the Server Configuration File Management page: Previous
Configuration, Configuration Backup Files, and Upload DASDEC II Configuration File.
A software upgrade results in the creation of two configuration update files. These serve as a precaution in the
rare event that an upgrade mangles an existing configuration. Either can be used to attempt to restore settings to
the pre-update state.

files are periodically available and can be obtained from Digital Alert Systems Customer Service.
IMPORTANT: Always backup your DASDEC II server configuration before installing an update. Go to Setup >
Server > Configuration Mgmt page and click on the
button. If you want, you can also download
any backup configuration file from the same page to a host computer for safe keeping. The 1.8-0 or later installer
automatically creates two configuration update files, one immediately before upgrade and one midway through
upgrade just before the current configuration files are modified by the upgrade. After the upgrade, these will
appear in the backup selection list on the Setup > Server > Configuration Mgmt page and are named
preinstall_2.0-0_config_1.zip and preinstall_2.0-0_config_2.zip. In case anything irregular happens during
the update, use your backup configuration file or one of these automatically created backups to re-install the
DASDEC II configuration settings.
The upgrade RPM file must be available from or on your local host computer’s file system to use this feature.
Type the path name of the file into the text box, or use the provided
button. This will pop up a
browse dialog of your local computer's file system that will allow you to locate the RPM file and fill in the path
information. Select the correct RPM file once it is found. Then, click
.
A confirmation page allows you to continue with or cancel the upgrade. After accepting the upgrade, an error
status is returned about the file if it is not an acceptable DASDEC II upgrade file. Otherwise, you will be logged
off the DASDEC II Web interface and will be directed to log back in after a short waiting period. The upgrade
should only take about a minute to complete. And to just emphasize the obvious but important, do not power off
the DASDEC II during the upgrade! The front panel LCD will display a message during the upgrade process. It
will also indicate when the DASDEC II is back to a login ready status.
Show Auxiliary Package Information
The main DASDEC II RPM software package is named 'DASDEC. Clicking on the button
expands the upgrade page to display auxiliary feature/security related packages that
can also be upgraded using the upgrade interface. Each auxiliary package is displayed along with an explanation
of its function, the currently installed version, and the latest known version (as known to the currently installed

DASDEC II package).
This expanded view also includes a special button
for repairing the internal
package database. Use this button to repair the RPM package database in case of package installation failure
due to RPM database corruption. THIS COMMAND SHOULD RARELY, IF EVER, BE NEEDED!
Once the packages are reviewed, click the button

Platform Configuration Options
Use this interface to set various platform options.
Server Debug Log Interface: This option enables or disables the DASDEC Debug Logs. This log is another
way for customer service at Digital Alert Systems to be able to view what is happening inside of the
DASDEC. If this option is enabled your DASDEC will keep track of these logs.
Select USB Port Speed Option: This option allows you to change the speed at which data is transferred
via USB in the DASDEC. This feature is important for some USB to Serial applications, where the USB to
Serial device may only support USB 1.1 and not USB 2.0. USB 1.1 Serial Adaptors need to run with USB
1.1 speed.
4.2
Setup > Network: Setup Network
There are two tabbed sub-pages on the Setup Network page: Configuration and Security. Use the sub-pages to
configure the DASDEC II to operate on a network by entering such information as:
 DASDEC II main and auxiliary network addresses
 DASDEC II network server hostname
 Static IP address
 DHCP to automatically acquire an IP assignment
 Netmask, optional DNS (domain name services), and an optional gateway value.
 Force use of secure http when using the Web browser.
 Management of ssh keys over a group of networked devices.
4.2.1 Configuration: Server Network Configuration
This page displays the current network state of the DASDEC II and provides interfaces to configure Server
Network Hostname, network Ethernet IP addresses, network gateway, and the static routes. It also displays four
informational sections about the current network configuration. These are the current network routing table, static
routes, network address configuration, and the contents of the /etc/hosts file.
The DASDEC II server can be configured to have static IP addresses or can use DHCP to automatically assign
network addresses. A second network interface can also be configured with a static or DHCP address. The
second network interface will only be enabled if the correct hardware is installed. Presently, the plug and play
USB-Ethernet Adaptor "Belkin F5D5050" is supported. Specific Ethernet PCI cards have not been tested or
approved, although many will work. The second network is usually meant to provide control and management
into a system that will use the main network for streaming MPEG, SCTE-18, or for sending other network based
alert data.
When a DASDEC II network interface is valid and operational, the web interface configuration box is displayed in
green and labeled "Enabled". Else, the interface box is the background color and labeled "Disabled". In the
example above, the main network interface is configured and enabled but the second network interface is
disabled, although it is fully configured, and is selected to be available. This would happen if the Ethernet adapter
is not present (for example, the USB-Ethernet adapter is unplugged).
24 Digital Alert Systems: DASDEC User Manual The primary network interface on the DASDEC II defaults to a static IP address of 192.168.0.200. This is a
commonly used, non-public IP address for LAN based appliance hardware. This value is meant to be changed.
The default IP netmask is 255.255.0.0. No default DNS or gateway is configured. If the gateway is selected, it
defaults to 192.168.0.1. The currently used IP address is displayed just above the entry field for the Server
Network Hostname. Information on other important system network configuration is displayed on the bottom half
of the page. See subsequent chapters for more information.
To save changes to the Network Hostname, Gateway, IP address or Second network interface option, you must
click
.
Setup > Network, Server Network Configuration (top half of web page)
4.2.1.1 Server Network Hostname
When configuring more than one DASDEC II, pick a unique Server Network Hostname. The name
cannot contain spaces.
The Server Hostname is different from the DASDEC II server name. (See Chapter 5.1.1 Main/License:)
The DASDEC II server name is the name the DASDEC II presents through its Web browser interface. It
serves to allow for simple identification of a viewed DASDEC II.
The Server Network hostname is the network name of the DASDEC II as defined by the underlying
Linux operating system. This name can also be very important for correct functioning of email.
Some email systems require a fully qualified network hostname (e.g. DASDEC II.mysystem.com).
If the DASDEC II has been given a network name by a system administrator, this name must be
entered here.
Digital Alert Systems: DASDEC User Manual

To submit changes to this name, you must click
.
4.2.1.2 Network Gateway Configuration
Three radio buttons are provided to select a gateway route option. The selections are No Gateway,
nd
Main Interface, or 2 Network Interface. A gateway is needed if the DASDEC II is to have direct
access to the internet or to other networks within a LAN, or if the DASDEC II will be multicast streaming
either MPEG Audio/Video or SCTE-18. If a gateway is required, either network interface can determine
the gateway address range; but there can only be one gateway, and it must be within one of the defined
networks. If a gateway option is selected, enter the IP Address of Gateway within the chosen network.
Although not required, the common value for a gateway address ends in 1 (#. #. #. 1).
To submit changes, you must click
.
4.2.1.3 Network Address Configuration
The DASDEC II network IP address can be manually configured to a static IP address or automatically
configured to a dynamically provided IP address via DHCP. Select the desired Network Type based on
your system requirements.
Network Type: Static (Manually Configure), Set the IP address manually)
To set a new static IP address, select Network Type > Static and then fill in the values for the
desired IP address and IP Netmask. If Domain name service resolution is needed, also select Use
DNS? and enter the corresponding values. The example above shows a new IP address of
192.0.0.23 and a netmask of 255.255.255.0, as well as a DNS (nameserver only) and gateway
configuration. DNS converts named IP addresses into the underlying numeric IP address.
DNS must be used if you configure any named IP addresses on the DASDEC II (instead of
numeric IP addresses). A likely requirement for DNS is to resolve an email server name.
To submit the new values, click
.
Network Type: Automatic (via DHCP), Set the IP address via DHCP
DHCP is a very convenient way to network a computer. It requires that your LAN be running an
accessible DHCP server. When DHCP is used, the IP address, the netmask, gateway and a DNS
server are automatically granted. To use DHCP on the DASDEC II, select Network Type >
Automatic (via DHCP). See screen shot below.
Setup > Network : DHCP Network Configuration
Then click
. Once the DHCP setting is accepted, the DASDEC
II will log you off. After a few seconds, you can log back in on the redirected address on the Login
page, as before.
26 Digital Alert Systems: DASDEC User Manual IMPORTANT! You must be CAREFUL when configuring a static network address if you are
configuring from a remote host. If an address which is inaccessible to your network is accepted for
the DASDEC II, you will not be able to log back in from the remote host.
Second network interface option
The Second Network Interface checkbox below the main Network configuration box controls use
of an optional second network interface. The default is value for this option disabled. Check to
enable display of a configuration interface for a second Network Interface Card (NIC) adapter.
As stated above, this interface will display in green and show a status label "2nd Network is
Enabled" when the adapter has been properly installed and configured. When enabled, it will also
display the IP address currently in use for the adapter.
Configuration of the second network adapter is similar to the main network. You must choose a
Network Type from Static (Manually Configure) or Automatic (via DHCP). If Manual Configuration is
chosen, enter the IP Address and the Netmask. The network part of the IP address for the second
network must be unique compared to the main interface network! Otherwise, either interface will
probably not function. For example, if the main network is 10.0.1. #, an obviously separate network
would be 192.168.1. #. There is not a separate DNS to configure for the second network. You can
also optionally set the hostname for the second network as it appears in the Linux /etc/hosts file.
When options have been configured, you must click
.
4.2.1.4 Network Status Information
Tables at the bottom of the Setup Network Configuration page show the current network routing
table, static routes, address configuration, and the /etc/hosts file. This information is provided to help
with network configuration and troubleshooting. The information is directly generated from Linux
network status applications and reflects the actual state of the DASDEC II network configuration. If the
network configuration is damaged, it is possible for the information in this table to not match the
configured values displayed in the user interface fields. The information in this table is definitive and
accurate.
Perhaps the most useful information is provided within the Current Network Configuration section.
Under the eth0 table is the IP address as the Linux OS sees it. This is the value provided next to the
label "inet addr:”. When a second network is enabled, a separate table will be shown for eth1.
4.2.1.5 Static Route Configuration
This simple interface allows statically defined network routes to be enabled or disabled and
added/deleted at network startup. Click the toggle box to Enable/ Disable a specific static route.
Digital Alert Systems: DASDEC User Manual
27
Setup > Network > Server Network Configuration (middle section of web page)
Static routes persist between rebooting of the DASDEC II. The DASDEC II comes preconfigured with
two static routes, either of which may need to be disabled depending upon the local area network.
These are 10.0.0.0 and 192.168.0.0. If the DASDEC II will be configured to run on a similar network, for
example 10.100.1.0, it is very likely that the default static-route of 10.0.0.0 should be disabled or
deleted.
NOTE: A conflicting route can block network connectivity.
Use the interface to control these requirements. The default static routes allow a DASDEC II to connect
to a 192.168.0.0 and 10.0.0.0 network by default, out of the box. Use this interface also to add other
needed routes out of your network. The provided user interface directly edits the file
/etc/sysconfig/static-routes. It is safe to directly edit this file as long as care is taken not to corrupt the
file. The contents of this file are displayed.

4.2.2 Security: Server Network Security Configuration
This page provides controls for managing network security. Two features are configurable for network security.
You can switch web access between secure mode (https) and regular mode (http). You can also use this page to
manage Secure Shell (SSH) keys across multiple platforms.
Web Interface Access Security
Use the Web Interface Access Security checkbox to force http SSL based communication to the Web Server.
The box is labeled Check To Only Allow https Secured Web Access to this server. If the box is checked,
browser access is forced to be via http. The change is immediate. All communications to the server will be
encrypted. Digital Alert Systems strongly recommends using this setting if the DASDEC II will be on a public
network
SSH Key Management Interface
WARNING: DO NOT MODIFY any SSH Keys without consulting with the factory!
Secure Shell is used for EAS NET network communication/control between a DASDEC II and other EAS NET
compatible platforms (including other DASDEC II's). SSH is a secure communications method that relies on
public/private key encryption. For a DASDEC II to communicate with another platform via SSH, the public key
from the DASDEC II's public/private key pair must be "authorized" on the remote platform.
Authorization usually is achieved by copying the public key into a file on the remote host. The DASDEC II uses
the open source package OpenSSH for SSH features. This package has a file called "authorized_keys2" under
/root/.ssh/ to hold the authorized public keys from remote platforms. Authorization allows secure access only
from the holder of the public key's corresponding private key. Even though this method of encryption and secure
access is very safe, it is still as a good idea to update the public/private keys from time to time. This can be
tedious to do manually between a set of servers that already intercommunicate. The DASDEC II SSH Key
Management interface greatly simplifies this process. It allows a group of remote hosts offering SSH connections
to have all of the encryption keys updated from the current DASDEC II location. This updates and maintains
secure SSH based network interoperability for EAS NET across each platform with a single operation.
Digital Alert Systems: DASDEC User Manual
29
To use this interface correctly, you must add client interface descriptors for each remote platform in the managed
group. The
button is used to create each descriptor. When a descriptor is added using this button,
there is no need to confirm the addition. The screen shot below shows a single remote client descriptor that was
added using
. Add as many as descriptors as needed. (EAS NET allows up to 8 connections.)
SSH Key Management Interface
Once a remote host client descriptor interface is added, it must be configured. Reasonable default values for
SSH connection to the remote host are provided (except for IP address). Type in the IP Address and change the
remote host User name, the SSH configuration path (directory), the SSH authorized keys file name, DSA public
key and private key file names, and management status file name if needed.
Changes to these Host text field values are not saved until you click
cancel changes by clicking the
. You can
button.
A very useful feature of this interface is that it provides network connection tests to remote hosts. Set the selector
SSH Connection Test to the desired test and click the button
.
You can try a variety of tests to prove SSH connectivity as well as network connectivity via "ping". Six tests are
supported:
1. "Ping". Use a simple network ping to test if the base network route to a remote host exists. To test
basic network connectivity, the ping test can be used without regard to the SSH field configuration.
Set the IP address (numeric dot.decimal format unless DNS is enabled) and run the Ping test using the

button.
"Uname" query via SSH (see example above). This will attempt to get the operating system name from
the remote host.
"Date" query via SSH. This will attempt to get the date and time from the remote host.
SCP test via SSH. This will attempt to copy a test file to the remote host.
"Key Management Status" query via SSH. This will attempt to retrieve the current state of the DASDEC
II key management status from the remote host.
"Get Public Key" query via SSH. This will attempt to retrieve the public key from the remote host.
Select a test and click the
button to see the test results. Be patient; it can take several seconds to
run some of these tests. Results are printed just below the
30 button.
Digital Alert Systems: DASDEC User Manual When you have all of the remote host descriptors entered properly, and you have confirmed SSH connectivity to
each remote host, you may safely update the public/private keys for the entire group by clicking on the button
. You may also return to the prior set of keys by clicking the button
.
The status of the last group management operation is printed just below the
button.
This gives a date and useful information about the last SSH management operation performed from this
DASDEC II.
The page display areas below the SSH Management interface provide two more useful pieces of information
about SSH. The first display shows the current SSH DSA Public Encryption Key and its installation date. Below
this is a printout of the "authorized keys" file. This shows remote hosts authorized for SSH connections to this
DASDEC II.
4.2.3 Proxy
Current Optional HTTP/HTTPS Proxy server assignments for getting CAP data
The server can be optionally configured to access remote http and/or https data (for CAP data) via a defined
proxy server address. Enter the hostname:port in the appropriate field. This option would be enabled if the user
wanted to use defined proxy servers for CAP data acquisition via HTTP/HTTPS.

Make changes to date and/or time and/or time zone, and then click Submit Date/Time/ Time zone Changes. If time
zone is changed, the DASDEC II will restart, and you will be forced to log back into the Web interface. If the time is set
forward far enough, you will also be forced to log back into the DASDEC II Web interface.
Official time link
If your browser has Internet access, click this link to pop-up a web page that displays the current official time.
Network Time Protocol (NTP) Configuration
The DASDEC II supports Network Time protocol (NTP) to synchronize its clock to another clock over a network. This will
synchronize the DASDEC II to an atomic clock over the Internet, or to another computer running NTP on your LAN, or to
another DASDEC II running as an NTP server on your LAN.
NTP Server name or IP Address:
Enter a name or dot notation IP address of a remote NTP server that is accessible from the DASDEC II LAN.
[ ] The checkbox for NTP must be checked to start NTP. If no NTP server name is entered and NTP is enabled, then the
DASDEC II will become an NTP server that can be pointed at from other DASDEC IIs over the LAN.
NTP Server Info
This is an informational display area that provides status about the NTP connection. Use this information to verify the
time offset between the DASDEC II and the NTP source server.
Public NTP Servers
Public NTP servers can be viewed by following the link provided.
NOTE: The computer hosting the Web browser must have Internet access to follow this link,
and the DASDEC II must be able to contact the chosen NTP server.
4.4
Setup > Users
The Setup Users page is to manage user accounts on the DASDEC II Web Interface. Only accounts with Administrative
permission are allowed into this page. Keep in mind that these user accounts are separate from the Linux system user
accounts. They do NOT control permissions to login to the base Linux system. From the Setup Users page, you can add
and delete user accounts, change the account Web Interface passwords, and set user permission levels. The Admin
account cannot be deleted, and only Admin can change the Admin password. Non-Admin accounts can be used to allow
users different levels of access. For instance, creating a user with View Only Level permission would allow EAS alert
activity report downloads without risking the chance of accidental changes to DASDEC II settings.
32 Digital Alert Systems: DASDEC User Manual Setup > Users web page
The DASDEC II allows multiple active user sessions. The same user or different users can be logged in more than once
and at the same time. A count of the number of active sessions is provided in the page header display on the right side of
the User:'accountname' text display. For instance, if Admin is logged on twice, the header displays User:Admin(2). The
total number of active sessions is displayed if that number is greater than the current user sessions. For instance, if Admin
is logged on twice and another user is logged on once, the header will display User:Admin(2)(3). Every active session is
managed separately; the page location within the Web interface can be different for the same user logged in twice.
However, keep in mind that virtually all of the provided controls and settings apply globally to the DASDEC II platform. If
two users with edit permissions are changing the same control (for example, tuning the radio), the last one to set the value
"wins". Refreshing the displayed page will display any changes made by other logged on users.
Edit Server User Account Profile

Setup > Audio
Audio is at the heart of an EAS system. From the factory, a DASDEC is configured ready for average field situations. The
EAS in your specific area could require some special tuning. At minimum, you will need to use the Setup Audio pages to
tune the Radio stations used for EAS monitoring. You will also likely need to adjust the decoder input levels for the
selected stations, since every station will vary in its signal strength. The audio output levels may also need some
adjustment to fit with your broadcast parameters.
38 Digital Alert Systems: DASDEC User Manual The Setup Audio pages provide a variety of easy-to-use controls and status displays to facilitate these tasks.
Due to the need for immediate feedback when tuning audio, the Setup Audio pages do NOT have an Accept Changes
button. Changes to check boxes, selection boxes, and clicking buttons on these pages are immediate.
NOTE: Some browsers will not accept the text edit change to an audio level until the
mouse is clicked outside of the field entry box. Other browsers simply will accept the
change when the Enter key is touched. You may wish to review Chapter 3.3.4.2 How to
Make Changes and Update.
There are four tabbed sub-pages on the Setup Audio page: Decoder Audio, Encoder Audio, Audio Output Levels/Tests,
and Radio Tuners. Start with Audio Output Levels/Tests.
4.6.1 Audio Output Levels/Tests: Direct Audio Output Levels and Tests
The audio output levels for the DASDEC audio output device ports are configured from this page. In addition, the
output sample rate and the audio preview devices group are configured here. Each audio output device results in
an audio configuration interface on this page. Finally, audio WAV and MP3 files can be uploaded into the
DASDEC from this page.
All standard DASDEC(s) from the factory have a Front Panel speaker, a Main audio output device, and one
auxiliary audio output device. A labeled configuration table is provided for each one of these output devices. The
configuration table provides controls for setting output levels from 0 to 100% and for running audio tests. The
table also displays if alert origination and forwarding will use the specific audio output. For the main audio output,
a toggle control is provided for enabling or disabling the analog audio pass-through option.
One other audio output option available that affects the page display. A second analog PCI soundcard can be
added in the factory to provide two extra decoders (for a total of six). This will result in a second auxiliary audio
device configuration table labeled Aux 2 Audio.
Audio tones can be played through each available audio output to test audio connections and calibrate levels
using audio test equipment. Configure the levels by entering numbers from 0 to 100 for any specific port. Output
level values near 70 are a good starting point for the DASDEC. Each audio device displays the same style of
table for the control interface. The table allows audio output level control, audio tests, and audio enable/disable
for alert forwarding and origination audio.
NOTE: Setup Audio web interface pages for Decoder and Encoder Audio display and
reference audio output levels for certain features. These references always provide an
active hyperlink into this page to allow for changes to audio output levels.

Main Audio and Aux Audio Tables
The interface tables for Main and Auxiliary (Aux 1 And Aux 2) audio operate much like the Front Panel
Speaker table described above. Auxiliary Audio is optional and thus may not appear. It is possible to have
two auxiliary audio interface tables. Also, Auxiliary Audio provides stereo output volume level control.
Otherwise, the same audio tests and alert audio toggles are presented.
Forwarding/Encoder Output Enable & Main Audio / Passthrough Audio
The Main Audio table has a special checkbox that controls the state of the Main analog audio pass-through
circuit. This circuit controls analog audio input/output pass-through on the screw terminal connector on the
back of the DASDEC. Pass-through audio allows external balanced audio to be passed through the
DASDEC and interrupted during an EAS audio activation.
If the Main audio output is to be tested by playing a file or a tone, or if pass-through audio is not needed, the
Main Analog Audio Passthrough toggle should be disabled. This will enable full time output of DASDEC
internal audio. Otherwise, check to enable analog audio pass-through. When Pass-through is Enabled, the
only time DASDEC generated audio is played on the Main audio output port is during an EAS alert.
Tests: To test the Main and/or Auxiliary Audio outputs, attach speakers to the DASDEC audio device output
ports and run the various tone test buttons. These tests allow the DASDEC to play each of the two single
tones that comprise the dual-tone EAS Attention Signal. The EAS Attention signal and WAV files can be
played as described above for the front panel speaker interface table.
Setup > Audio > Audio Output Levels/Tests web page, bottom sections
Alert Forwarding and Alert Origination: The Main and Auxiliary Audio tables display an active hyperlink
showing whether the forwarded and originated alert audio is output on the audio device. To make changes
to these states, click the text link to jump to the correct Decoder or Encoder Audio setup page and modify
the associated checkboxes.
5. Upload Audio .WAV file to DASDEC Server
The interface at the bottom of the page allows Wav and MP3 files to be uploaded into the DASDEC. Click
to locate the file on the host computer file system, then click
. MP3 files will be
converted automatically into a WAV file on the DASDEC. Uploaded audio files are available for tests as well
as for encoding and manual forwarding.
4.6.1 Radio Tuners
The standard DASDEC supports three internal radio receivers. These can be configured, tuned, and monitored
on the Radio Configuration page. Each radio can be programmed to any AM, FM, or NOAA frequency.
NOTE: External antennas are usually required for proper radio reception. Antennas are
connected to a coax connector on the back of the DASDEC II. Antennas can be
purchased through third party vendors. For recommendations, contact Digital Alert
Systems.
42 Digital Alert Systems: DASDEC User Manual Setup > Audio > Radio Tuners web page
For a radio to be used by a decoder channel, the decoder must be set to the internal audio source that indicates
a radio is available (displayed per decoder under the Setup Audio > Decoder Audio page).
NOTE: It is important to tune the radios to stations that carry EAS alerts. This is a
fundamental part of setting up your DASDEC II for monitoring the Emergency Alert
System.
The chosen radio frequency settings are automatically recalled at boot time or whenever a software restart is
done. A numeric level indicator displays the strength of reception. FM, AM and NOAA band selection occurs
immediately. NOAA frequency selection occurs immediately upon button selection. Typed frequencies for AM
and FM must be submitted using the
button.
As a convenience, the decoder channel associated with each radio tuner is displayed in an active web link. This
can be clicked to immediately traverse over into the Setup > Audio > Decoder Audio page.
Digital Alert Systems: DASDEC User Manual
43
NOTE: It is VERY IMPORTANT to verify radio reception and decoder input levels
after tuning. Radio reception can be monitored using the provided Listen on:
buttons for each radio. When you select one of the speakers listed, audio from the
associated decoder for the radio will play-out of the chosen output. To stop the audio
play-out, click on the Turn Radio Monitoring Off button that will be displayed above the
radio tuning sections. Radio frequencies can be tuned while listening.
NOTE: DO NOT LEAVE THE MONITOR ON DURING NORMAL OPERATION
NOTE: The Decoder Audio Monitoring interface provided on the Setup Audio > Decoder
Audio page can also be used to listen to radios. It is less convenient than using the
buttons provided on the Radio Tuners page. It is necessary to use the Decoder Audio
Monitoring interface to listen to the fourth decoder input or to listen to decoders five and
After tuning and verifying reception, check the input levels on the Setup Audio > Decoder Audio page and
make sure they are rated as OK (or occasionally Elevated).
4.6.2 Decoder Audio: Alert Decoding Audio Configuration
The Decoder Audio page has three areas to configure: Alert Decoding Audio, Decoder Audio Monitoring, and
Alert Forwarding Audio Configuration. For Administrative users, a fourth configuration option, Sound System
status and configuration, appears at the bottom of this web page.
Each EAS decoder channel can be independently tuned for input sensitivity and can be enabled and disabled.
Decoder input can also be heard using the audio monitoring controls on this page. The audio output devices
used during alert forwarding are also configured from this screen.
To make changes effective on Setup Audio web pages, see NOTE under the Chapter 5.6 Setup > Audio.
1.
Main and Auxiliary Audio Decoder Configuration
Each analog soundcard (Main, Auxiliary) has its own decoder status and configuration display table.
NOTE: the AES digital audio card does NOT support EAS decoding. Each table
has a radio button selector for the Audio Input Source. Each soundcard supports two (2)
decoder channels. Decoders can be selectively enabled and disabled and the input
levels can be set. The interface is described below.
Soundcard name and associated Linux mixer device
The name of the soundcard and its associated Linux mixer device name are shown above the display table.
Audio Input Source: Internal/Radio or Line-In Jack
To the right of the soundcard name is a radio button control that indicates the analog audio input source for
the soundcard. This can be Internal Radio or Line-In Jack. The input source selection switch is VERY
important since it controls the origin of the audio input stream used as the EAS audio source. Typically this
will be set to the Internal/Radio setting for the Main Audio device. To connect external radio receivers, use
the Line-In Jack setting on the appropriate sound card device.
If Radio is selected, a link to the Setup > Audio > Radio Tuners page is provided in the first column on the
display table as a convenience.
The standard DASDEC has three built-in radio receivers. Two are connected to the main audio device. The
third is connected through the Audio Input Source "Internal A" connection. A fourth audio source, from the
back panel screw connector terminal, is also routed through this input channel.
44 Digital Alert Systems: DASDEC User Manual When a new input source is established, refresh this page a few times to insure a consistent level quality of
OK. This page redisplays more slowly than most other DASDEC web pages, so be patient when you
access or refresh this page.
Soundcard decoder pair display table
Each table provides names and controls for two decoders to be selectively enabled and disabled and for
decoder input levels to be set. Typically, all decoders can be enabled. The DASDEC-1EN supports two EAS
decoders per stereo line input channel. This results in each soundcard device providing two decoders, one
on the left channel and one on the right channel (L1 and R1). Each decoder is displayed in a separate row in
the soundcard status table. Each row has four columns to review and configure.
The audio soundcard table columns are:
1) Decoder Name, Label and Info – The decoder base name, automatically set by server, provides an
identification tag for the decoder. The input text field provides for each decoder channel to be given a
user label for identification of the channel in other interface pages. Also, if the Audio Input Source is
set to Radio, a link to the Setup > Audio > Radio Tuners page is displayed as a convenience.
2) Audio Input Level (1..100) – Change the input level as needed until the Audio Level Status is OK
(green) or occasionally Elevated (yellow).
3) Audio Level Status – EAS Decoding is sensitive to audio input levels. Input level status is
automatically rated at Zero, Low, OK, Elevated, or High and color coded. The quality of the input level
is constantly being rated in real time per decoder on the DASDEC server. When you use the
button in the standard header of the page, the Audio Level Status quality is redisplayed. This assists
in setting the correct level setting.
Each decoder is also given a
button. When a
button is clicked, a WAV file of the
corresponding decoder audio input buffer is saved on the DASDEC, dated, and displayed as a web
link accessible via this web page. This can be a great aid for troubleshooting and testing audio.
The file is named based on the decoder channel name and can be downloaded via the provided web
link. In the screen shot, four snapshot files are shown:
L1 snapshot (Fri Jan 4 16:38:38 2008): L1_snapshot.wav
L1 Last Post Decoded Alert Snapshot (Tue Jan 8 09:19:26 2008):
L1_post_alert_snapshot.wav
R1 snapshot (Fri Jan 4 16:36:32 2008): R1_snapshot.wav
R1 Last Post Decoded Alert Snapshot (Wed Jan 16 11:17:12 2008):
R1_post_alert_snapshot.wav
Two of these are snapshots generated by the
button, the other two, Post Decoded Alert
Snapshots, are generated automatically after decoding has finished. See the Decoded Alert AutoSnapshot option below.
4)
Decoder Enable – Two toggles are provided to enable/disable a decoder and EAS Auto-scale. A
decoder must be enabled to decode EAS alert audio.
EAS Auto-scale is a method to automatically increase the input gain level when EAS alert data is detected.
This can result in decoding alerts that have low audio levels from the source.
Decoded Alert Auto-Snapshot checkbox
A toggle box located below the decoder status/configuration tables allows you to enable or disable the
Decoded Alert Auto-Snapshot. This feature should usually be enabled. It results in a snapshot WAV file
being generated after an alert is decoded or after a decode error is detected. This feature allows detailed
troubleshooting in the case where incoming EAS audio has resulted in decoder errors. Careful analysis of
the post-alert snapshot audio can pinpoint the nature and source of upstream EAS errors.

Decoder Audio Monitoring Configuration
Two interfaces in this section of the page allow a DASDEC user to hear the audio from a selected decoder
input.
1) The Select Decoder Audio to Monitor list presents all of the decoder audio channels available to hear.
2) The Decoder Audio Monitor Output list allows a specific output port to be selected to hear the audio
chosen in Select Decoder Audio to Monitor.
46 Digital Alert Systems: DASDEC User Manual Setup > Audio > Decoder Audio web page: middle section
To operate, choose a decoder channel and select an output port that has speakers (or the Front Panel
Speaker). DASDECs with EAS NET licensed provide two streaming audio output ports for remote input
audio monitoring. This is especially useful for checking the decoder input when the DASDEC is monitored in
an office that is apart from the equipment room. Your browser host computer will need a streaming audio
player that can support either OGG/Vorbis audio format or MP3.
The selections occur immediately and will cause a page refresh. When audio monitoring is enabled, a bright
Red **ON** label will be displayed to the left side of the interfaces. To disable audio monitoring, select
the None decoder option and/or the None output option.
NOTE: DO NOT LEAVE THE MONITOR ON DURING NORMAL OPERATION!
Temporarily listening to the decoder input is a VERY IMPORTANT part of configuring the
DASDEC for EAS reception. Make sure that these tools or the Radio monitoring button options
are used after radio tuning in order to verify audible reception. See Chapter 4.6.4 Radio Tuners for a
description of the Radio monitoring buttons.
Front Panel Speaker Audible Decode checkbox is useful to hear when alerts are being decoded. When
enabled, audio for an incoming, decoding alert, is played on the front speaker. This toggle defaults to
Disabled.
3.
Alert Forwarding Audio Configuration
Audio Output Sample Rate
This selector controls the sample rate of audio played from the DASDEC.
NOTE: This same control is presented under Setup > Encoder Audio > Alert
Encoder Audio Configuration and under Setup > Audio Output Levels/Tests. The
sample rate applies to audio for both alert Forwarding and Origination.
NOTE 2: AES Audio output requires 32000 or more samples per second.
Digital Alert Systems: DASDEC User Manual
47
Audio Forwarding Tables
After the DASDEC decodes an EAS alert, it can be triggered to "Forward" the alert. The audio component of
forwarding is the action of playing the alert audio over selected audio outputs. The Main audio device is
always present on a DASDEC. Auxiliary Audio outputs are present if an appropriate sound card has been
installed. A standard DASDEC always has the Aux 1 sound device. Use the checkbox provided per table
under the column Forwarding Output Enable to set base station audio port forwarding.
NOTE: Forwarding and encoding share the same physical output ports; level
changes for one applies to the other.
Audio Output Level - The Audio Output level is displayed and provides an active shortcut link to the Audio
Output Levels/Tests page to change the output levels.
Forwarding Output Enable - Each audio device is given a tabular interface that allows for
enabling/disabling base station audio forwarding on the device. Each table provides a checkbox for
controlling if base station forwarded audio is played using the output device. Typically, these should all be
enabled.
Multistation mode note: When DASDEC Multistation mode is enabled, the audio forwarding configuration
for each station overrides the settings on these tables! Configure station alert audio forwarding on the
proper station interface configuration page under Setup > Decoder > Forwarding.
[ ] Alert Audio Delay checkbox
The toggle for Alert Audio Play-out Delay is used to control a delay period before the play-out of alert audio
after the EAS Audio play-out relay is closed. When enabled, a numeric text field is provided for entering user
specified number of seconds of delay.
NOTE: This same control is presented under Setup > Encoder Audio > Alert
Encoder Audio Configuration. The delay time applies to both alert Forwarding and
Origination.
4.
48 Sound System status and configuration - For Admin user only.
Choose to run or restart the ALSA or OSS sound systems using these buttons. The sound system is
configured in the factory and only should be changed under the direction of DAS customer support. In very
rare cases, restarting the sound system can solve unusual audio problems. The AES digital audio option
requires ALSA.

4.6.3 Encoder Audio
There are two main configuration options for encoder audio: Alert Encoding Audio Configuration and Alert Audio
File Recording.
1.
Alert Encoding Audio Configuration
When the DASDEC encoder is used to originate an EAS alert, the audio associated with the alert must be
played out of an output port in order for the alert to be transmitted or decoded by another decoder. The
audio for the alert must be configured to play over a selected audio output. This interface allows for setting
audio sample rate, enabling/disabling Originating audio on each of the audio output devices, and for setting
a play-out delay time.
Audio Output Sample Rate
This selector controls the sample rate of audio played from the DASDEC.
NOTE: This same control is presented under Setup > Decoder Audio > Alert Forwarding
Audio Configuration and under Setup > Audio Output Levels/Tests. The sample rate
applies to audio for both alert Forwarding and Origination.
NOTE 2: AES Audio output requires 32000 or more samples per second.
Main Audio and Auxiliary Audio Tables
These tables allow for examining audio output status and enabling/disabling playing base station Originated
alert audio on the individual audio output devices. The Main audio device is always present on a DASDEC.
Auxiliary Audio outputs are present if an appropriate sound card has been installed. A standard DASDEC
always has the Aux 1 sound device. The table has two columns: Audio Output Level and Encoder Output
Enable.
NOTE: Encoder Origination and Decoder Forwarding share the same physical
audio output ports; level changes for one applies to the other.
Audio Output Level - The audio output levels are displayed and provide an active shortcut link to the
Audio Output Levels/Tests page to change the output levels.
Encoder Output Enable - Each table provides a checkbox for controlling if base station originated
alert audio is played using the output. Typically, these should all be enabled.
Multistation mode note: When DASDEC Multistation mode is enabled, the alert origination audio
configuration for each station overrides the base station settings on these tables! Configure station
alert audio origination on the proper station interface configuration page under Setup > Encoder >
General.
Alert Audio Delay
This toggle below the tables allows for delaying the play-out of alert audio for a user specified number of
seconds after the EAS Audio play-out relay is closed.
NOTE: This same control is presented under Setup > Encoder Audio > Alert
Encoder Audio Configuration. The delay time applies to both alert Forwarding and
Origination.

Select audio device for alert audio file recording
The DASDEC Encoder provides an interface to record audio into WAV files (EG. the audio file recording
interface is available under the Encoder > Send EAS > General EAS web page). These files can then be
used for the voice audio portion of an EAS alert. This page provides for selecting which audio device and
input source (microphone or line input) is used for the recording.
NOTE: An active link to this page is provided wherever the audio recording
interface is presented.
Use the ALSA sound system when directly recording WAV files on the DASDEC. ALSA supports a mic
boost that results in clearer, louder, audible recordings.
Sound card source - The standard DASDEC provides one Auxiliary Audio card in addition to the Main
audio card. When more than one sound card device is present, a radio button selection option for the
recording sound card will be displayed. Select the card to use as the recording source.
Input Source - Once the source sound card is selected, set the Input Source to either Microphone Input or
Line Input Left. The selection is determined by the actual source from which you will record.
Record Input Level - Use the Input Level control to set the level for the recording input gain level. Enter a
value from 0 - 100 in the Record Input Level field. After you set the value, you must click on the text "(click

external and internal character generation.
In Broadcast mode, there are six tabbed sub-pages on the Setup Main Serial CG Options page: Video Out, Main Serial
and USB Serial 1 through 4 for up to four expansion USB serial ports. Broadcast mode DASDEC II's support up to five (5)
simultaneous serial ports (one main RS232 port on the back panel, and 1 to 4 expansion RS232 ports provided via a USB
port expander), each running a different character generator protocol.
Non-broadcast mode DASDEC II's only have a single page interface that combines the Video Output options with the
Main Serial port options. Non-broadcast mode DASDEC II's support only the main serial port.
The DASDEC II can also optionally provide native analog NTSC composite video output. Video/CG behavior is configured
only on this page and applies to both Decoder Alert Forwarding and Encoder Alert Origination.
Changes to each Setup Video page require submitting modifications using the
Button. You may wish to
refer to Chapter 3.3.4.2 How to Make Changes and Update for details on making changes to pages with this button.
Start with the Main Serial page.
4.7.1 Main Serial
The Main Serial sub-page has three sections: Serial Port Character Generator Configuration; selected CG
Attribute Settings; and FIPS and EAS Codes filter configuration. Information in each section is reviewed below.
1.
Serial Port Character Generator Configuration
The radio selection buttons show the Character Generator (CG) used when a decoded alert is forwarded or
encoded (or no CG). There are eight supported character generator protocols: Monroe Envoy, Monroe
CEMS-0500/1000, Standard TFT, Chyron CODI, VDS 840, Sage Generic CG, DecadeNet XBOB, and
BetaBrite LED sign. Of these, the Monroe CEMS-0500/1000, VDS 840, and DecadeNet XBOB require a
DASDEC II TV license. The Chyron CODI interface requires both a DASDEC II TV and a Plus Package
license.
Choose the appropriate protocol for the connected serial device and check that option. The CG should be
connected to the server serial port (on the back panel) using the correct serial cable (TFT, CODI, VDS use
NULL modem cable, Monroe CGs use straight through cable, SAGE Generic depends on specific CG,
usually a straight through cable). Use SAGE Generic for Evertz MediaKeyer and Logo Inserters as well as
for Miranda Imagestore Cgs. Most of the character generator protocols present some further configuration
options. Some, like Chyron CODI and VDS840 present direct control of alert repetition, font colors, number
of crawl loops, etc. Experiment with these settings to get the desired behavior. The CODI protocol also
presents options for generating test patterns. Most CG's also can be configured to run repetitions of the
video output during an alert. The available CG's and protocols are described in Chapter 9 - DASDEC II
Peripherals.
2.
CG Attribute Settings
The options displayed here depends on the selected CG protocol. The screenshot shows the SAGE Generic
CG has been chosen. So, for SAGE Generic, a user would choose the correct settings for Serial Port Baud
Rate, Serial Port Flow Control, Iterations; and Repeat Alert Video Display. There is also a checkbox to
toggle the Throttle down serial port write speed from Enabled to Disabled.

4.7.2 USB Serial 1 through 4
The USB Serial sub-pages have the same organization as the Main Serial port page and operate in the same
way. Each page corresponds to a different physical serial port.
These ports are supported using the Serial Gear CS-42042 USB to 4 Port RS232 Adapter. Other adapters may
work, but they must be based on the FTDI chipset. As with the Main Serial Port, make sure that the proper cable
54 Digital Alert Systems: DASDEC User Manual is used for the external CG hardware.
The USB serial ports offer a few different choices for CG's from compared to the Main serial port.
CG protocols are: Off; Monroe R194 CG; CEMS-0500/1000; Standard TFT; Chyron CODI; VDS; Sage Generic
CG; Sage News Room; XBOB; XBOB4; CG BETABRITE LED Sign; Monroe Envoy; BDI GPM – 300 Matrix
Switcher. The SAGE Newsroom protocol is only available on the USB serial ports. The Monroe Envoy protocol is
NOT available on the USB serial ports. The TFT standard protocol is available, but only one instance of the
protocol will actually be allowed to control audio play-out on the DASDEC II. The first instance configured on
Main or USB ports 1-4 would be granted the privilege of running audio.
Setup > Video/CG > USB Serial 1 web page
As with the Main serial port, a status box is also displayed above the CG radio button selector to inform of the
status of the specific USB serial port. If the port is available (the USB expansion unit is installed) on the DASDEC

A standard DASDEC II will run two EAS decoder channels from the Main audio device and two from the Auxiliary Audio
device. It will decode EAS out of the box, once the Master license key is valid. However, a variety of useful options can be
configured to tune the decoder for operation in a specific system within a specific geographic region. All decoder
60 Digital Alert Systems: DASDEC User Manual configuration options can be accessed through the Setup > Decoder sub-pages.
The Setup Decoder Forwarding Options page has four tabbed sub-pages: Forwarding, Local Access Forwarding,
Demo Decode/Forwarding and Other.
A Decoder only DASDEC II will present a fifth tabbed page, Required Tests. This page requires a FIPS location code for
the geographical location of the DASDEC II. The location code will be used for the One-Button Weekly Test. The interface
also supports configuring random Weekly Test generation. See Chapter 4.9.2 Setup > Encoder > Required Tests for
information on the random Weekly Test interface.
Due to the need for immediate action when setting forwarding options, the Setup Decoder pages do NOT have an

4.8.1 Forwarding: Decoder Forwarding Configuration
Setup > Decoder > Forwarding header screenshot
The Decoder Forwarding Configuration sub-page is used to configure EAS alert forwarding. Forwarding is
when a decoded EAS is relayed out an audio output of the DASDEC II, presumably into a broadcast audio
signal. Forwarding can be automatic or manual. Forwarding can be set so that all alerts to any FIPS area are
forwarded, or it can be highly constrained so that only a select few EAS codes to specific FIPS areas are
forwarded. Use this page to configure station identity settings and to select how EAS alerts are forwarded. To
select the actual audio output port(s) for forwarded alerts, use a different Web Interface page. See Setup >
Audio > Decoder Audio. Active and expired Forwarded alert events can be examined in detail on the Decoder
> Forwarded Alerts event display page.
There are seven main configuration controls on this page:

Configure Auto or Manual Forwarding Operation
One of the essential decisions that an EAS participant must make is whether to run an EAS decoder in
Auto-forwarding mode or in Manual forwarding mode. This section of options provides the controls over
these two basic options.
The text box on the left side of this section will indicate the current forwarding state. It will display either
"Auto-Forward Mode is Enabled" or "Manual Forward Mode is Enabled." The same information is also
prominently displayed on the Decoder > Incoming Alerts pages. To set the Auto-Forward Mode or the
Manual Forward Mode look to the checkbox to on the right side of this section.
Auto-Forward Mode checkbox: Check (enable) the first toggle box on the right side of this section to
select Alert Auto-Forwarding. Uncheck to select Manual Alert Forwarding. The toggle box will display a
standard label that says if Auto-Forward Mode is Enabled or Disabled and which mode is currently
selected.
When Manual forwarding is set, a user of the DASDEC II must use the Web Interface or use GPI input
contact closures to actively forward any unforwarded alerts from the Decoder > Incoming/Decoded
Alerts Active Decoded list display.
During Auto-Forward mode, the DASDEC II forwards alerts without review or intervention provided they
pass the currently configured Auto-Forwarding criteria.
NOTE: Emergency National Activation (EAN) and Termination (EAT) alerts always
forward automatically.

Plus Package License version features
Manual Forward Control – Plus Package licensing enables the user configurable option of
applying the Auto-Forward EAS and FIPS code filters to the pending manual alerts. This feature
allows an extra measure of protection against accidental forwarding. When this option is used,
pending alerts that DO NOT pass the Auto-Forward filter criteria will be blocked from Manual
Forwarding by not displaying the Manual Forward button. Instead, such alerts state that they are
blocked and provide a quick link back to the Setup > Decoder > Forwarding interface. Following
the link back to the Manual Forward control interface allows the control mode to be changed at will
in case it is too restrictive.
There are three levels of control:
1. Off
2. Apply the Auto-Forwarding criteria to just the manual alert forwarding buttons.
3. Apply the Auto-Forwarding criteria to both manual alert forwarding buttons and the GPI input
forwarding actions.
Setup > Decoder > Forwarding, middle section of web page, showing Forward Mode Timers
All licensed versions feature two Forward Mode Timers that can be enabled independently to
automatically switch the DASDEC II between Manual and Automatic Forwarding modes. The timers can
be set to run on a daily basis, or just on weekends or weekdays. Each timer provides a time setting for
enabling Auto-Forwarding and later disabling Auto-Forwarding. Active timers override the toggle for
setting Auto/Manual Forward Mode. The timers allow a station to schedule auto-forwarding when
unmanned and manual forwarding at other times. For both timers, the start time and the stop time fields
need to be modified by the system administrator to configure when the DASDEC II will go into AutoForward mode and it will go back to Manual mode. In the screen shot above, Auto-Forward Mode is
active from 11PM to Noon on Weekdays and all day on Saturday and Sunday.
4.
Configure Pending Alert Acknowledgment
When an EAS alert is decoded during Manual forward mode, while active, it causes the red front panel
status light to flash until the alert is acknowledged. Alerts can be acknowledged from the Decoder >
Decoded Alerts page or by pressing the front panel button. In addition, some configuration options are
associated with alert acknowledgment.
Plus Package License version features:
Pending Manual Forward Acknowledge Announcement
Each type of alert category can be configured to play-out an audio announcement on the front panel
speaker during the time the alert is manually pending forward and before it has been acknowledged.
Use the provided selectors to control audio announcement for each alert severity category.

5.
Configure Duplicate EAS Alert Handling for Decoder Auto-Forwarding
If an incoming EAS alert is determined to be an exact duplicate of a previously decoded alert, it is
completely discarded and a message is logged in the operation log. However, EAS alerts that are
duplicates except for Station ID or ORG code are stored as a decoded alert and can be optionally autoforwarded or held. Use the selector to choose the setting to control manual or auto-forwarding for these
alerts.
The Configure Update Policy for Active EAS Alerts option, allows you to expire an active alert when
a new alert is decoded and updates the previous alert. When enabled, you can choose what
requirements the new alert must have to expire the previous active alert.
Setup > Decoder > Forwarding Web Page, Configuring Handling of Duplicate Alerts
The following is an example of this situation: Two local radio stations are being monitored; both send
out a Monthly test for the same FIPS codes, and with the same start time and duration, but the stations
have changed the station ID. The alerts arrive several minutes apart. The DASDEC II has been set to
auto-forward Monthly tests to the given FIPS codes. The first decoded Monthly test is forwarded
automatically. The user has configured the duplicate alert handling to NOT auto-forward duplicate alerts
that differ in Station ID or ORG code. The second alert is decoded, but is held for manual forward.

4.8.1.1 Forwarding: Multistation Decoder Forwarding Configuration
Multistation operation leverages the flexibility of the DASDEC II platform to provide EAS operation for
up to five collocated broadcast channels or stations from a single DASDEC II. When Multistation mode
is licensed, the Decoder Forwarding Configuration sub-page is used to configure both system wide
base station forwarding options and for single station option bindings that control individual station
forwarding.
The base station configuration is simply the sum total of the DASDEC II options that enable system
wide control over video character generators (CGs), GPIO relay outputs, audio output ports, and
network alert connections. When the various DASDEC II Setup web pages are configured you are
creating the base station configuration. DASDEC IIs without the multistation mode only use the base
station configuration. When the Base Station Info interface is edited on the Setup > Decoder >
Forwarding web page, you are configuring the decoded alert forwarding options for the base station.
See the screen shot.
Digital Alert Systems: DASDEC User Manual
67
Setup > Decoder > Forwarding page showing Base Station options
The main purpose of multistation mode is to enable targeted EAS alert origination/forwarding to specific
collocated stations.
IMPORTANT NOTE: This does not lessen the importance of base station forwarding.
Correct base station forwarding is critically important in multistation mode. It is used for
National Alerts (EAN and EAT) and for selected high priority alerts requiring quick
propagation to the public. In both cases simultaneous alert broadcast must occur on the
entire set of DASDEC II controlled stations. Make sure the DASDEC II will correctly
broadcast an EAS to ALL stations with a single alert broadcast while in
multistation mode.
68 Digital Alert Systems: DASDEC User Manual Correct station configuration allows one DASDEC II to propagate (during alert origination or forwarding)
EAS alerts sequentially to any one of the set of collocated stations (or broadcast channels). During
setup, this is achieved by choosing an exact subset of the base station DASDEC II hardware
connections for each individual station (or channel). The choices are made within a station configuration
interface on the Setup > Decoder > Forwarding web page. The resulting station interface configuration
permits an EAS alert to play on the broadcast hardware for a specific station channel (or channels). In
this way a specific video CG can host an alert text crawl and a specific broadcast program audio path
(tied to the video crawl) can have EAS alert audio inserted on demand. As alerts are played in
sequence this way, the proper audio/video hardware is controlled from the DASDEC II to achieve alert
play-out on a single chosen station.
Setup > Decoder > Forwarding page showing an enabled station name Station 1

The screen shot above shows an example of a station configuration interface from the Setup >
Decoder > Forwarding web page.
NOTE: Many of the settings on the page also apply to alert Origination. If so, the label of
the control will state that the setting applies to both Orig/Fwrd.
Most of the options for a station can be thought of as providing an override action when compared to
the same option used or available during base station operation. For instance, the base station has a
control point to determine if the NTSC video details page is displayed during alert play-out. Each station
provides its own control for whether or not video details are used. Serial port operation provides another
useful example. The base station defines a set of serial ports that are used during alert play-out. Each
station interface must be configured to select which of the available base station serial ports are be
used for the station during alert play-out.
Here are the interface options for the page.
1.

To edit station settings, use the pull down menu Select Station Configuration Interface to
select any station other than Base Station Info. This will display a special set of selection
options for the station.

Forwarding Station ID
This text field determines the EAS station ID used for the station during decoded alert forwarding.
This ID appears in many other places on the DASDEC II user interface where station references
are made. It is encoded into the EAS alert header audio when an alert is forwarded to the station.
This value is used in place of the Base station Forwarding Station ID.
NOTE: This value can be different from the Origination Station ID. However, typically
these should be the SAME. In the Forwarding Station ID is edited and becomes different
from the Origination Station ID, the GUI will display a notice of the fact and provide a
shortcut active link to allow quick editing of the Origination Station ID.

substitution for the standard translation of the EAS ORG code.
8.
Multi-selection Settings
A set of selection box interfaces are presented for choosing station level hardware control. Most
of these options apply equally during both alert origination and forwarding! The selection
box label will indicate which controls are shared for both alert origination and forwarding.
With these controls, the station can be set to use specific audio outputs, serial ports, GPO relays,
Network GPIO relays, EAS NET clients, streaming Mpeg clients, etc.
NOTE: The selected serial ports and network client interfaces MUST be enabled in the

Setup > Encoder
To run EAS encoding, a DASDEC II must first be configured with a valid Encoder license key. Verify or enter the license
key on the Setup > Server page. See Chapter 4.1.1 Main/License: Server Name & License Key Configuration. Without a
valid license key, the DASDEC II will not show a Setup > Encoder page nor the main Encoder menu tab.
EAS alert encoding is when the digital codes and alert audio tones and message defined by the EAS protocol, are
assembled into a complete audio sequence for play-out over a broadcast medium for which EAS decoders might be
listening. This process is call origination when the alert is encoded for the first time on an EAS platform.
The DASDEC II makes EAS alert origination very easy. Every action needed to encode and send any kind of EAS alert is
available on a single page of the DASDEC II Web Interface, under the Encoder > Send EAS pages.
But before you use the DASDEC II encoder, there are some configuration tasks that must be done on the Setup Encoder
General Options, on the sub-page General EAS. The tasks are explained in this chapter.
There are three tabbed sub-pages on the Setup > Encoder screen: General, Required Tests, and Other.
Due to the need for immediate action when setting encoder origination options, the Setup Encoder pages do NOT have
an Accept Changes button. Changes to check boxes, selection boxes, and clicking buttons on these pages are
immediate.
NOTE: Some browsers will not accept the text edit change until the mouse is clicked
outside of the field entry box. Other browsers simply will accept the change when the
Enter key is touched. You may wish to review Chapter 3.3.4.2 How to Make Changes
and Update.
4.9.1 General: Main Encoder Configuration
Setup > Encoder > General
The Main Encoder Configuration sub-page is used to set the basic encoder values such as EAS Origination
code, Origination code custom text substitution, the EAS station ID, and commonly used alert types and FIPS
locations. These basic items are needed for using the EAS encoder for originating any alert.
76 Digital Alert Systems: DASDEC User Manual 1.
Basic EAS Encoder Values Setup
The top section on this screen provides controls to set the basic values to construct an EAS alert.
EAS Origination (ORG) Code
The ORG code is a standard part of the EAS audio protocol. It is placed in the EAS alert message when the
encoder originates an EAS alert. The same code is also used for forwarded alerts. Multistation operation
allows this value to be overridden per station definition. This code categorizes the type of organization
sending the EAS. Use the selection menu to choose the EAS Origination code for your system:
 Broadcast station or cable system: Choose EAS
 Civil authorities: Choose CIV
 National Weather Service: Choose WXR
 Primary Entry Point System: Choose PEP
Custom text for origination (ORG) code string: Default is disabled. The origination codes are given a
standard text translation when an encoded EAS alert is sent to a video display. When an EAS origination
Code is used, the alert text will start with the phrase "A Broadcast or Cable System has issued". Checking
the Custom Text option allows a custom translation to be used instead.
In the screen shot below Custom Text is enabled. When enabled, a text entry box is displayed in which you
can enter the organization name issuing the alert for Custom Origination (ORG) Code Translation. In the
screen shot, the phrase, "The Digital Alert Systems DASDEC II,” has been entered as the custom text. Thus
EAS translation text will use this phrase instead of the generic "A Broadcast or Cable System"; the phrase
`HAS ISSUED` follows the custom organization name in the alert translation.
Setup > Encoder, EAS Origination Code, top section of web page

77
EAS Station ID
Type up to 8 characters in this text field to identify the Station ID for this DASDEC II. This code is included in
all originated alerts, both manually forwarded and automatically forwarded alerts.
NOTE: Encoder Station ID can be programmed differently from Forwarding Station
ID, although usually they should be the same value.
Attention Signal Duration
This control allows setting the duration of the two-tone attention signal from 8 to 25 seconds.
Block Origination and Manual Forwarding during in progress alert announcement
Check to block manual play-out of a new alert while another announcement is in progress.
Weekly Test Audio
Default is disabled. This checkbox controls whether the originated Weekly Test (RWT) can be constructed
with an audio message.
Segmented Alert Origination
Default is disabled. This checkbox controls whether the option for segmented alert origination is available on
the Encoder > Send EAS pages. Segmented alert origination is when the alert header and attention signal
are played with a pause for live audio voice dub. A separate button then allows the play-out of audio files
and EOM. (In EAS, the End of Message (EOM) is signaled by the final three FSK audio bursts.)
TDX controls on Send general EAS page

2.
Configure Available EAS Types for Encoder Alert Origination Interfaces
The DASDEC II must be configured for the types of EAS alerts that will be available for selection during alert
origination encoding. This is done by constructing a list of alert types to be held in a common pool. The list is
referred to on the DASDEC II as the "Configured Available Encoder EAS Codes". The list appears on the
Encoder > Send EAS > General EAS screen (See Chapter 6.1.1 General EAS).
Setup > Encoder, Available EAS Types, middle section of web page
Choose from All EAS Codes:
To build or edit the available EAS code pool list, choose one or more EAS code types from the selection
box list and click
. Codes selected for encoding will appear in the Configured Available
Encoder EAS Codes box to the right. Be sure to add all common EAS types that will be used when
encoding alerts from this DASDEC II. If you find you are missing a code during encoding, you can edit
the pool list at any time.

.
3.
Available Encoder FIPS Codes
This section is labeled Configure Available FIPS Pool for Encoder in the user interface. The DASDEC II
must also be configured for the commonly used FIPS locations that will be immediately available for use
during alert encoding. Just as for the available EAS Codes list, a commonly used list of FIPS locations are to
be constructed from the list of all possible FIPS. The list is referred to on the DASDEC II as the "Available
Encoder FIPS Locations". There are thousands of FIPS location codes, so building this pool of commonly
used FIPS codes saves time during typical alert encoding construction. In the rare event that other FIPS
locations are needed, the pool can be edited at any time.
Choose one or more FIPS location codes using the FIPS Subdivision selector, the State (or territory)
selector and the County (or County Equivalent) selection box. Multiple selections can be made at the same
time from the County selection box. Then click
. FIPS locations selected for use in the encoder alert
construction interface will appear in the Configured Available Encoder FIPS Locations field to the right.
Be sure to add all the common FIPS codes that will be used when encoding alerts from this DASDEC II.
Otherwise, while constructing an alert, you may have to return to this screen to add any FIPS codes that are
missing from the Encoder FIPS Pool on the Encode and Send an EAS Alert screen.
To remove a location from the FIPS pool, select one or more lines in the Decoder Auto-Forwarded FIPS
field and click
.
All operations are immediate.

84 Digital Alert Systems: DASDEC User Manual 4.10 Setup > Net Alerts: Setup Network Alert Protocol Options
There are up to six tabbed sub-pages on the Setup Network Alert Protocol Options page: EAS NET, CAP Decode,
DVS644 (SCTE18), Net CG, Net Switch and Net GPIO. All features, except Net GPIO and parts of Net CG require license
keys to operate.
One of the benefits of the DASDEC II's inherent network nature is that it can support a variety of methods for network
forwarding/origination of EAS alerts, alert audio/video, and remote control. The DASDEC II supports several network
protocols. The EAS NET protocol provides a variety of flexible methods to send alert notifications and data from a
DASDEC II to a remote host (including another DASDEC II). The EAS NET protocol includes support for multiple DVS168 network clients. Another network EAS protocol supported as a licensed feature on the DASDEC II is DVS-644/SCTE18 alert messaging to cable systems. For video and audio, the DASDEC II can uni-cast or multicast an MPEG2
video/audio details page. This, in conjunction with EAS NET or DVS-644, provides a complete digital solution in one box
for EAS requirements. All of these features, when licensed, appear as tabbed pages under the Setup > Net Alerts.
Most of the Net Alert interfaces can be separately enabled / disabled per feature and per client interface. The standard
Networked GPIO supports FIPS programmable LAN based relay triggering during alerts and alert states.
If a required network interface is not available, it can be enabled using the License Key Manager interface under Setup >
Server. (See Chapter 4.1 Setup > Server: Setup Server.) You must purchase a license key from Digital Alert Systems,
enter the key into the appropriate License Key Manager field, and enable the protocol by restarting the server.
Select one of the protocols for editing by selecting the appropriate tabbed sub-page on the main Setup > Net Alerts
page.
All of the Setup > Network Alert Protocol Options pages use an
Button for submitting option changes.
Multistation mode note: When DASDEC II multistation mode is enabled, the Net alert client interfaces used per station
are selectable. Thus, a station can choose to NOT use an enabled Net Alert interface. The station assignment options do
not allow reprogramming of a Net Alert interface, just its inclusion. Also, the specific included Net Alert interface MUST be
enabled for the station to be able to trigger its action. This allows specific Net Alert interfaces to be assigned to different
stations and thereby trigger a Net Alert action only when a specific station is active. Configure per station used Net Alert
assignments on the proper station interface configuration page under Setup > Decoder > Forwarding.

When an alert is forwarded to a DVS-168 client, a WAV file of the EAS audio is constructed and a text file of
the alert details is constructed. These are FTPed to the DVS-168 client. Then a socket is temporarily opened
from the One-NetSE to the DVS-168 client, and a control message is sent that describes the alert. The
Operation Log will log each of these actions and their success or failure.
4.10.2 EAS NET
There are three sections on the EAS NET sub-page to configure: EAS NET Decoding, Web audio streaming,
EAS NET Clients.
1.
Configure EAS NET Decoding
EAS Net Decoding is included with the EAS NET license key.
Discussion: EAS NET Basic Operation
EAS NET operates by sending optional audio, optional text translations, and an EAS event notification file
from a DASDEC II to a remote device over a LAN or WAN. There are some differences depending upon the
chosen EAS NET protocol. SSH STDIN Only does not offer sending of digital audio WAV files or text
translations. DVS168, being a legacy protocol, does not send the same type of event notification data as the
other protocols. For everything but DVS168, the remote host/server device is sent an event text file or ASCII
data sequence that contains a set of key=value style data lines describing the EAS alert. For every protocol
but SSH STDIN Only and DVS168, the text event file by default is copied into the remote host file
EAS_NET_ALERT under the remote user home directory. This filename and path can be overridden when
configuring the client schema file. A standard set of information fields is sent in the text file, but the actual
names of the keys can be custom edited per client according to a programmable schema. Each client can
be set to use the Default schema or can use a custom edited schema. The DASDEC II EAS NET client
interface provides a schema editor to create specialized schemas.
There is only one toggle button to enable EAS NET decode. Check the toggle labeled "EAS_NET decode
from remote EAS NET sending devices". The DASDEC II will then be able to receive alerts sent via EAS
NET send from a properly configured remote DASDEC II. EAS NET decoded alerts are clearly labeled in the
Decoder > Decoded Alerts status page as being received from input channel EASNET. The alert event
files are stored in a separate disk storage area from audio decoded alerts. Other than those differences,
Digital Alert Systems: DASDEC User Manual
87
EAS NET decoded alerts are handled the same as alerts decoded from the audio inputs. Click the
button to save changes.
Setup > Net Alerts > EAS NET Configure EAS Decoding
2.
EAS NET Web audio streaming
Discussion: EAS Net Client Web audio Streaming is included with the EAS NET license. This provides a
convenient way to stream live alert audio over a network. This is used primarily to provide live EAN/EAT audio
from EAS NET send to an EAS NET client device (including another DASDEC II). The stream is not an MPEG
transport stream. It is an http audio stream. Remote clients must actively load the URL for the stream in order
to play it. This can be done via most modern media players. A DASDEC II with EAS NET decode will
automatically use this audio stream as a live input for EAS audio as needed. Refer to the screen shot below.
EAS_NET Web (HTTP) Alert Audio streaming during alerts.
Enable this toggle to generate live web streamed audio during alerts. The default values of the options are
designed to work for EAN/EAT.
Audio Streaming on all alert types
This checkbox controls audio streaming for National Alerts (EAN/EAT) or all alert types. For testing
purposes, the toggle "Audio streaming on all alert types" can be enabled to allow all alert types to
have audio streaming. Make sure to use this button to test live audio for any remote DASDEC II EAS
NET decoder.
Audio Stream Format
You can select either OGG/Vorbis or MPEG Layer 3 (MP3) audio. For audio to a remote DASDEC II
EAS NET decoder, use OGG.
Audio Output Sample Rate Pull-down menu
The correct value for this depends upon the destination. For audio to a remote DASDEC II EAS NET
decoder, use the output sample rate selected on the remote DASDEC II. Choices are 16000, 32000,
44100, and 48000 samples/sec.
Pre-Alert audio/alert header/attention inclusion at start of audio stream.
Pre-Alert EOM Audio Streaming
These two toggle options are included for control of the total content of the alert audio that is streamed.
For purposes of this interface, alert audio consists of three parts: (1) Pre-Alert audio/EAS Alert FSK
header/Alert Attention signal, (2) Alert audio voice message, and (3) Alert FSK EOM audio. No matter
the choices, the second part, alert audio voice message, if it exists, is always streamed. Any
88 Digital Alert Systems: DASDEC User Manual combination of these options will work when streaming to a remote DASDEC II EAS NET decoder. The
default is to not stream the header or EOM sequence, just the audio voice message. Use the options as
required by the specific application on a remote server.
To review, the options allow the inclusion/exclusion of:
1. Pre-Alert audio/EAS Alert FSK header/Alert Attention signal
2. EAS alert FSK EOM.
Delay time before stream start; Starting silence duration; Ending silence duration: This option
allows streaming to be delayed by the duration of the alert header. Three numeric text fields allow entry
of three additional audio delay components. Each delay is in seconds and applies to a specific location
during the audio stream. Use as needed for the specific application.
Setup > Net Alerts > EAS NET Configure EAS Web audio streaming
3.
Configure EAS NET Clients
Two toggles are displayed for enabling EAS NET during alert forwarding and origination.
Alert Forwarding to EAS_NET devices
This toggle enables EAS NET send processing during alert forwarding. It can be enabled / disabled at any
time.
Encoder Originated Alerts Sent to EAS_NET devices
This toggle enables EAS NET send processing during alert origination. It can be enabled / disabled at any
time.
Decoded Alerts Can be sent to EAS_NET devices
This toggle enables EAS_NET send processing during alert decoding. Decoded alerts can be sent to
another EAS_NET device without forwarding and putting it on the air.
NOTE: At least one of these toggles must be enabled to allow editing of EAS NET clients. In
the screen shot below, both toggles are enabled.
Digital Alert Systems: DASDEC User Manual
89
Setup > Net Alerts > EAS NET Configure EAS NET Clients
Configure EAS_NET Client Connection
Once enabled, you can create configurations for up to 8 EAS NET clients. Each client can be independently
enabled and disabled, allowing an easy way to stop or restart a client for a specific region.
If no client configurations exist, or if you want a new one and less than 8 clients exist, click the
button to create a new interface configuration.
To edit an existing client interface, select the named client from the pull-down menu Select EAS_NET client
and edit the fields provided in the table underneath.
To delete a client configuration, select the client and click on
Interface.
Client
To duplicate an existing client interface (a different name will be automatically generated; less than 8 clients
must exist), select the
button. This is the best way to create new
client interfaces that are mostly the same as an existing one except for the IP address.
Careful! EAS NET client configuration addition, duplication, and deletion is immediate and
cannot be canceled.
Discussion: The screen shot below demonstrates an example client configuration. The controls are
described below. The example shows an EAS NET client interface configured to use Secure Copy to send
the alert information and audio files to a remote DASDEC II host. This DASDEC II would need EAS NET
Decode enabled to receive the alert.
During alert processing, the Operation Log will log the success or failure of the EAS NET
forwarding/origination action per client.
NOTE: Every client configuration is used for whichever action of alert forwarding and alert
origination is currently enabled by the toggles described above.
EAS NET uses a flexible set of LAN communication protocols to send EAS data to a remote device.
Generally, the remote device needs to have running software that understands EAS NET files and data
formats in order for anything useful to be triggered by an EAS NET event. All EAS NET protocols will send
an alert event data notification file or ASCII data string from the DASDEC II to the EAS NET remote server
host. Most protocols also allow for sending separate data files (like audio WAV files).
Various information fields must be configured to identify and correctly communicate to the EAS NET remote
client. Common to all are the following:
Client Interface Name - This text box allows the client interface to be given a descriptive name. These
names appear in the selection list.
Client Enable/Disable - This toggle provides a quick method for enabling and disabling the EAS NET
client.
Remote EAS NET Host IP Address - The field displays the IP address of the remote EAS NET host
where the EAS NET event info is sent.
EAS NET Event Transfer Protocol - Displays the Event Transfer protocol. This is simply the LAN
communication method used to send the alert event data. Depending upon the Event transfer protocol,
other configuration fields are necessary or optional. Some protocols require passwords; others use
90 Digital Alert Systems: DASDEC User Manual encryption keys. Most also provide for optional data file connections.
The event transfer protocol options are:
1.
Secure Copy (SCP) – Uses the Secure Shell (SSH) network protocol for both the data file transfers and
event file transfer. No passwords are needed. For all of the Secure Shell protocols (1.3), passwords are
not used. Instead, the DASDEC II public ssh key id (under /root/.ssh/id_dsa.pub and also displayed at the
bottom of the Server > Status > Network page) must be added into the remote host's authorized ssh
keys list. The keys provide for encrypted data transfer and for secure authentication without a password.
2.
Secure Shell STDIN Only (SSH) – Uses the Secure Shell (SSH) network protocol for the event file
transfer. No data files can be sent. This protocol requires that the receiving device read the EAS NET
event file from Standard input from within the shell script. In such a configuration, SCP and SSH login to
the EAS NET user will not present to the remote platform shell.
3.
Secure Shell STDIN & Copy (SSH with SCP) – This is a variation on protocol #2 above. The event file is
sent as in #2. But the Web interface will display a field to enter a second user account for sending data
files to the remote host. The Secure Shell (SSH) network protocol is used for both transfers.
4.
File Transfer Protocol (FTP) – Uses the File Transfer Protocol (FTP) network protocol for both the data
file transfers and event file transfer. A password is required. FTP does not encrypt or secure passwords
during transmission. The password is sent in clear text to the remote host FTP demon. If security is an
issue, do not use or design an FTP based EAS NET scheme. Some FTP daemons refuse passive port
connections. Use the provided checkbox to enable a non-passive connection if needed.
5.
TCP event notification – Uses a TCP socket from the DASDEC II to the remote host to send the alert
event file. For sending the optional data files, one of FTP or SSH SCP network protocols can be selected.
A valid user account on the remote host must be entered. The information described above for passwords
and keys apply depending upon the chosen data protocol.
6.
DVS168/EARS – This is a special case of EAS NET. A TCP socket is used to communicate an event
notification, while FTP is used to send data files.
7.
Legacy Mediaroom – This is a special protocol bundled under EAS NET when the Microsoft©
MediaroomTM option is licensed.
8.
Mediaroom2 – This is a special protocol bundled under EAS NET when the Microsoft© Mediaroom
option is licensed. This is in accordance with the Mediaroom 2.0 software.
9.
MINERVA – This is a special protocol bundled under EAS NET when the Minerva option is licensed. A
TCP socket is used to communicate an EAS event notification as per the Minerva protocol.
TM
10. WideOrbit – This is a special protocol bundled under EAS NET when the EAS NET Automation option is
licensed.
11. RCS Nexgen – This is a special protocol bundled under EAS NET when the EAS NET Automation option
is licensed.
Remote EAS NET Host Port - The field displays the port on the remote EAS NET host where the EAS
NET event info is sent.
EAS NET User - Displays the user account name on the remote device. Files sent to the remote host
will by default be copied relative to this account home directory.
Current Schema
The schema determines key names of the information fields sent to the EAS NET client's remote host. It
also determines file names and paths for any files sent to the remote host. The schema can be edited
by clicking on the Edit/Review Schema button.

NOTE: The schema does NOT set the values of the client interface fields.
Other possible EAS NET Client Configuration Options
Not all of these options will appear for every EAS NET transfer protocol.
Client sends EAS NET alert info during alert play-out
When this option is enabled (checked) the EAS NET alert info is sent out prior to alert play-out. EAS
NET prior send is only needed with EAS NET compatible equipment that depends upon GPI controlled
delayed alert play-out.
SSH Public Encryption Key link.
The SSH based protocols provide this link to the display of the DASDEC II public key. This must be
copied to remote host's authorization file.
Composite Audio File Send
When enabled (checked) a composite WAV file of the entire EAS audio track will be sent as a separate
file to the EAS NET client's remote host. The file name and path on the remote host are determined by
the schema.
EAS Audio File send
When enabled (checked) the individual audio sections of the EAS alert will be sent as separate files to
the EAS NET client's remote host. The file names and path on the remote host are determined by the
schema.
Translation File Send
When enabled (checked) the EAS text Translation will be sent as a separate file to the EAS NET client's
remote host. The file name and path on the remote host are determined by the schema.
Translation File Newline Control
When enabled (checked) the EAS text Translation has all newline characters removed. When disabled,
the EAS text Translation includes newline characters.
Video Start Delay Factor (0-10 seconds)
When set to a non-zero value, this adds delay time to the video start time reported in the EAS NET
event file. This can be useful to handle latency between the DASDEC II and the EAS NET remote host.
Duration Extension Time (seconds)
This allows extra time to be added to the internally calculated duration time in the EAS NET event file.
Alert Duration == Audio Duration + Extension Time
All FIPS codes trigger
If enabled, all alert FIPS codes will trigger the EAS NET client interface. In the next screen shot this option is
disabled. Set the checkbox to enable/disable FIPS code filtered trigger control. If disabled, then the alert
FIPS codes are filtered for at least one specific match as a way to control whether or not EAS NET is
triggered. Alerts for specific FIPS areas can be filtered as a way to control whether or not EAS NET is
triggered. If All FIPS is disabled, select FIPS codes from the provided Encoder FIPS pool or the Forwarding
FIPS pool lists and add to the client FIPS list. If any of these FIPS are included in the incoming active
forwarded/originated alert, the alert will be sent using the EAS NET client. With careful use of this feature,
and with multiple clients, one DASDEC II can serve many different cable regions at the same time.

Discussion: Since EAS NET is used in conjunction with third-party management software (on the remote
host), typically, configuration details will depend upon the exact third-party solution. Often instructions will be
provided by this party. Configure the EAS NET client interface as required.
DVS168/EARS devices
DVS168/EARS can be selected as an option on the EAS NET Event Transfer Protocol selector. See the
screen shot below. Like the other EAS NET protocols, the EAS NET remote host IP address and port must
be entered. This would be the address and port of the DVS168/EARS server. Standard DVS168 uses FTP
to send data files, so an EAS NET FTP user and password value must also be entered for a standard client
configuration. However, there is an option to disable the FTP send. This is for servers that do not support
handling digital file data but can be alerted by the DVS168 event protocol. If this option is checked the FTP
user and password values are not displayed or needed since the audio and video files will not be sent.
Digital Alert Systems: DASDEC User Manual
93
Setup > Net Alerts > EAS NET Client Configuration - DVS168/EARS
94 Digital Alert Systems: DASDEC User Manual Two other options unique to the DVS168 protocol are also provided.
1.
To send just the EAS alert audio message, instead of the EAS FSK header and EOM audio and
attention audio, use the provided checkbox. Before using this option, it is important to make sure your
local EAS plan allows the FSK audio to be discarded.
2.
Alert duration data format. Typically, this is in minutes, but some DVS-168 interpreters have coded this
differently. The selector provides two other interpretations.
The DVS168 protocol does not provide a programmable schema. For DVS168, the data schema is
predefined and the schema selection is not displayed. As with the other EAS NET protocols, the Video Start
Delay time, the Duration Extension time, and FIPS based net alert triggering are all configurable.
When you finish making changes, click

DVS168/EARS operation - When a forwarded/originated EAS alert is to be sent using a DVS-168 EAS NET
client, a TCP socket is temporarily opened from the DASDEC II to the DVS-168 remote host. If this
succeeds, and the alert is a non-national alert (and FTP is enabled), a WAV file of the EAS audio and a text
file of the alert details are FTP'ed to the DVS-168 remote server host. Then a control message is sent over
the TCP socket that describes the alert and provides names for the data files. For non-national alerts, this is
the only notification by TCP needed. For EAN and EAT national alerts, the audio and text files are not
generated or sent, since EAN/EAT alert audio is live and of undetermined duration. When the alert ends, a
second control message is sent over the TCP socket to signal the end of the national alert. After this, the
socket connection is "torn-down". The Operation Log will log each of these actions and their success or
failure.

The CAP PUSH INPUT is available if you want to Receive CAP Alerts from a remote push server.
Though this option is available, it is not used often. If it were used, FEMA would have to know all of the
specific IP addresses that it was pushing CAP Alerts to. Because FEMA does not know your DASDEC’s
IP Address location, it is not going to push an alert to you this way. It is recommended that this client
interface is disabled.
For the HTTP Get Client1 default option, you can choose between a few CAP Polling Protocols. Choose
between HTTP, HTTPS, SSH and the IPAWS Open 2.0 option.

98 Digital Alert Systems: DASDEC User Manual 4.10.4 DVS644 (SCTE18)
Configure DVS644 (SCTE-18) Client Alert Send to DVS644 (SCTE-18) device
Discussion: DVS644/SCTE18 is an SCTE standard for encapsulating EAS alert data into an MPEG transport
stream format (as an MPEG system table) for delivery to MPEG client devices (such as set-top boxes and cable
ready TVs). The DASDEC II has a sophisticated and powerful implementation of this standard.
As stated above, this feature requires the DVS644/SCTE18 license. WhenDVS644/SCTE18 support is available
on the DASDEC II, the tabbed sub-page for this feature appears under Setup > Net Alerts. Two toggles are
displayed for enabling DVS644/SCTE18 during alert forwarding and origination.
Alert Forwarding to DVS644/SCTE18/CEAM devices. This toggle enables SCTE18 send processing during
alert forwarding. It can be enabled / disabled at any time.
Encoder Originated Alerts Sent to DVS644/SCTE18/CEAM devices. This toggle enables SCTE18 send
processing during alert origination. It can be enabled / disabled at any time.
At least one of these toggles must be enabled to allow editing of DVS-644/SCTE 18 clients. In the screen shot
below, both toggles are enabled.
If either of the first two toggles is enabled, a third toggle box is displayed that controls application of the defined
Audio Delay value to DVS644/SCTE18 alert send action.
Setup > Net Alerts > DVS644/SCTE18 web page - top half
Configure DVS644 (SCTE-18) CEAM Client Connection (client IP & program values apply to both
Origination and Forwarding)
Discussion: Up to 64 DVS644/SCTE18 client interfaces may be defined. Each one can have a unique
configuration and can send the SCTE18 EAS protocol data to different IP address. During alert play-out
processing, the Operation Log will log the success or failure of the DVS644/SCTE18 forwarding/origination
action per client. Individual client interfaces may also be enabled and disabled. Every enabled client
configuration is triggered for whichever action of alert forwarding and alert origination currently enabled.
Select DVS644 client - This interface lists the names of the existing client interfaces in a drop-down menu. It
also prints the current number of defined client interfaces. The maximum number of client interfaces is 64. To
edit an existing client interface, choose the named interface from the pull-down menu to edit.

100 Digital Alert Systems: DASDEC User Manual DVS-644/SCTE18 Client Configuration Interface, top half of table
Discussion: Various information fields must be configured to identify and correctly communicate to the DVS644/SCTE18 client. The most basic fields are the Remote Host Unicast or Multicast and Remote Host Port.
Enter these addresses according to the specific DVS-644/SCTE-18 target server. Often this is an MPEG-2
multiplexor, such as a Stream Encryptor Modulator, serving a defined set of digital cable channels.
Multicast TTL - This value determines the number of router hops that are allowed during multicast of the
DVS644/SCTE18 Cable Alert Message before the UDP message is blocked. Enter a sufficiently large value
(from 0..200) if you are multicasting. Multicasting requires proper configuration of a network outside the DASDEC
II.
Advanced DSG Delivery - Defaults to Disabled. The default method for delivering the DVS644/SCTE18 Cable
Alert Message MPEG2 system table uses a standard MPEG2 Transport Stream. Check to switch to Advanced
DSG delivery. Use DSG delivery for communicating with DOCSIS Standard Gateway equipment.
If Advanced DSG delivery is used then the a text field option is displayed for setting the Network MTU (Max
transmission unit) is available. This defaults to 1500 but can be set lower if needed based on a specific network.
Digital Alert Systems: DASDEC User Manual
101
If standard MPEG2 transport stream delivery is used, then the following option to select In-Band or Out-ofband communication is available:
In-Band. Check to Enable. If not checked (disabled) then Out-of-Band (OOB) communication of the DVS644/SCTE18 message is made.
Discussion: The DVS-644/SCTE18 Cable Alert Message is an MPEG2 system table structure. It is typically
placed into the MPEG2 Transport stream and routed to the downstream cable set top boxes (STB) or SCTE-18
enabled TV's. Thus the ultimate target for the DVS-644/SCTE18 alert message is a set-top box (STB) or a cable
ready TV. Keep in mind that the actual EAS alert handling is performed by the STB or TV. Although standard
practices exist for these actions, some differences can and do exist. The processing of the Cable Alert Message
on the STB determines the actual response to the alert seen by a viewer. For alerts below a certain priority (by
default, this would be the highest priority, 15), a crawl message is typically run on the video display for every
channel. For alerts at or above this priority, the video channel is forced to a details channel. Based upon whether
this channel is available at the STB as In-Band or Out-of-Band, set the Details Major/Minor number or the
Details Video/Audio OOB channel numbers. This details channel is where the highest priority force tune alerts
are switched. EAN/EAT will always cause a force tune to this channel.
Details Video OOB ID/ Details Audio OOB ID - When the alert details channel is an Out-of-Band channel; set
the provided video/audio channel field. An audio channel designation is not required when there is another
means to provide the alert audio. A value of 0 means not used.
Details In-Band Major/Minor Channel - These two fields are for programming the digital in-band Major/Minor
channel number of the in-band force tune details channel. A value of 0 means not used.
Exception Channel List - This interface allows specific In-Band and Out-of-Band channels to be excluded from
the alert response of the STB. These channels will have their own EAS. When enabled, the interface controls
allows creation of any number of exception channels.
MPEG Audio Sync Private Descriptor - Check to enable the MPEG Audio Sync Private Descriptor method.
This is a special private descriptor for synching a DASDEC II MPEG2 A/V stream to the DVS644/SCTE18
message processor. Use of this method requires custom support by the DVS644/SCTE18 message processor.
NDS Tune Private Descriptor - Check to enable the NDS Tune Private Descriptor method. This is a special
private descriptor for synching a DASDEC II to an NDS system. Use of this method requires custom support by
the DVS644/SCTE18 message processor.
Private Descriptor Interface
Generic Private Descriptor Check to enable an interface to create one static DVS644/SCTE18 Private
Descriptor. Use of this method requires custom support by the DVS644/SCTE18 message processor.
102 Digital Alert Systems: DASDEC User Manual Alert Type Priority Selection Use this interface to configure the associated priority number for EAS alert codes.
The scheme is based upon five EAS groups: Advisories, Tests, Watches, Warnings, and Emergencies. The
exact alerts that fall into each category is defined on the DASDEC II at Server > Help > EAS Codes.
Discussion: DVS644/SCTE 18 provides for 16 priority values. However, reserved uses for most values mean
that in practice, priority values are 0, 3, 7, 11 and 15, with 15 being the highest priority alerts. The priority of 0
has a special meaning. An alert sent with 0 priority will establish a new set-top box or TV sequence number. The
sequence number is incremented (modulo 32) whenever an alert is sent with updated information. The DASDEC
II supports this reset mode by allowing an alert to be set to 0 priority. This setting should only be used for one
alert, and then changed to 1-15. There is also a field to extend the alert duration past the default DASDEC II
audio duration. Keep in mind that the maximum allowed time for a DVS644/SCTE 18 message is 120 seconds.
Immediate Start (Alert Start Time)
This checkbox toggle sets the EAS Alert message start time on receiving device. When enabled, the start time of
the alert on the receiving device is immediate upon reception. When disabled (unchecked), the Alert Start Time
is set to use a clock based start time. The actual time used is the EAS alert UTC. If a clock time is used, it is
CRITICAL that the DASDEC II and the receiving device be time synchronized.
Alert Text Control
This pull-down menu list programs when the alert text section of the DVS-644/SCTE18 message is sent, based
on alert priority. This feature allows text to not be sent if the priority becomes higher than a specified value. This
allows the STB to omit alert text crawls when a force tune to a details channel is made based upon alert priority.
Alert Repeat Control and Alert Message Repeat Period
The DASDEC II can be configured to periodically resend the alert message, with the DVS-644/SCTE 18 Cable
Alert message field alert_time_remaining field decremented automatically. This is controlled using the Alert
Repeat Control selections. The options are based on alert priority, allowing repetition to be invoked for alerts
above a given priority. When repetition is selected, the Alert Message Repeat Period field for entering the time
period (in seconds from 6 to 60) is also displayed.
Alert Message Transmission Duplication Count (1-20)
When a forwarded/originated alert is sent to a DVS-644 client at a specific IP address, the DVS-644/SCTE-18
MPEG-2 System table is generated and sent to the MPEG multiplexor client. Programming this interface controls
the number of times the table is sent as a duplicate, from 1 - 20 times, to insure downstream reception.
Additional Start Delay Time (seconds)
This toggle allows time to be added before the DVS-644/SCTE-18 Cable Alert Message is first sent over the
network. The formula for the delay time is: Start Delay == (Audio Delay if enabled) + Additional Time.
Duration Extension Time (seconds). - This field allows some extra time to be added to the alert duration
programmed into the Cable Alert Message alert_time_remaining field. The maximum time allowed for this field
is 120 seconds. This can be used to guarantee a minimum amount of time for short Weekly Test alerts. The
formula for the Alert Duration is: Alert Duration == Audio Duration + Extension Time (max total is 120 seconds).
All FIPS codes trigger
If enabled, all alert FIPS codes will trigger the DVS644/SCTE18 client interface. In the next screen shot this
option is disabled. Set the checkbox to enable/disable FIPS code filtered trigger control. If disabled, then the alert
FIPS codes are filtered for at least one specific match as a way to control whether or not DVS644/SCTE18 is
triggered. Alerts for specific FIPS areas can be filtered as a way to control whether or not DVS644/SCTE18 is
triggered. If All FIPS is disabled, select FIPS codes from the provided lists and add to the client FIPS list. If any
of these FIPS are included in the incoming active forwarded/originated alert, the alert will be sent using the DVS644/SCTE18 client. With careful use of this feature, and with multiple clients, one DASDEC II can serve many
different cable regions at the same time.

4.10.5 Stream MPEG
If Streaming MPEG hardware/software is available on the One-NetSE, a tabbed page will display under Setup >
Net Alerts that allows configuration of up to two client targets. As in the other Net Alert pages, use the Alert
Forwarding and/or the Encoder Alert Stream toggles to enable/disable the use of streaming MPEG clients when
alerts are forwarded and/or originated.
104 Digital Alert Systems: DASDEC User Manual Addition/deletion, configuration, and enable/disable for each client interface is handled just like the other Net
Alert interfaces described above. Unlike those interfaces, there are a few global settings that affect all Streaming
clients. These control the video/audio format and encoding bitrate of the stream (from the hardware). The user
can also program if they want Audio/Video, Audio only, or Video only being encoded. To account for the latency
of starting up stream encoding and actually streaming, a delay of a few seconds is needed before audio is played
for a net forwarded/originated alert. Audio delay status and a link to the configuration field for audio delay is
provided.
Streaming MPEG requires very few configuration fields. A unicast or multicast IP address must be set, along with
a port. The Multicast TTL value must be set high enough to insure the multicast data is sent past all the LAN
SE
routers between the One-Net and the destinations. Also, as with the EAS NET and DVS644 interfaces, FIPS
and EAS code based triggering is supported per client.

are forwarded and/or originated.
Addition/duplication/deletion, configuration, and enable/disable for each client interface are handled just like the
other Net Alert interfaces described in the previous chapters.
The first option is to choose a Client Interface Name. This is to name the CG to reduce confusion between
multiple devices.

All FIPS codes trigger. Check to enable all alerts, regardless of FIPS codes, to trigger a crawl on the target
CODI. Uncheck to only allow alerts for specific FIPS areas to trigger the crawl. When unchecked, you can
select from the Encoder FIPS pool or the Forwarding FIPS pool to add the list of allowed FIPS that trigger
this CODI alert send. After a set of FIPS codes have been selected, use the
button to add the selections to the filter list (labeled as the Streaming CODI CG Net client FIPS List). Alerts
to these locations will be sent to the remote CODI.
All EAS codes trigger
If enabled, all EAS codes will trigger the Net CODI client interface. Set the checkbox to enable/disable EAS
code filtered trigger control. If disabled, then the alert EAS code is filtered for a specific match as a way to
control whether or not the target CODI is triggered. If All EAS is disabled, select EAS codes from the
provided lists and add to the client EAS list. If the EAS code of an active forwarded/originated alert matches
any of these EAS, the alert will be sent using the Net CODI client. With careful use of this feature, and with
multiple clients, one DASDEC II can serve many different cable regions at the same time.

4.10.7 Net GPIO: Configure NET GPIO Clients
This sub-page under Setup > Net Alerts is a standard feature on a DASDEC II to allow remote, LAN connected
GPIO relays and inputs to be associated to active alerts. The DASDEC II supports the Titus Technology WR-300
module with four relays (the same hardware as the Monroe Electronics R190 Hub Controller), the Control-byWeb Web-Relay Quad with four relays (the same hardware as the Monroe Electronics R190A Hub Controller)
and Web-Relay Dual module with two relays and two inputs. This interface page provides for creating,
duplicating, deleting and configuring client connections for up to eight LAN positioned relays. This type of
hardware provides an inexpensive and convenient way to expand the contact closures relays of the DASDEC II.
Since these relays can be placed on a LAN, and controlled by the DASDEC II remotely, they can be used to
trigger actions during alerts without extra wiring. Configuration is much like the other Net Alert pages. Up to 8
clients can be configured and active at a time.

Configure Net GPIO Connection
Following is a brief description of the client interface controls.
Select client: Use the pull-down menu to select the client interface to examine or configure.
[ ] Listen for Net GPIO Input. When Enabled this checkbox causes the DASDEC II server to listen for input
contact closures from the Net GPIO units. This option only works if at least one of the connected Online Net
GPIO units supports inputs. As of DASDEC II version 8.0, only the Web Relay Dual unit supports inputs. Only
enable this option when an input from a Net GPIO unit is required.
Because a Net GPIO unit must be continually queried via HTTP for an input contact closure, this option is slow
compared to GPIO input hardware that is directly a part of the DASDEC II. Thus this option requires the contact
closure to last for at least one second in order to be detected.

108 Digital Alert Systems: DASDEC User Manual NET GPIO Output Relay Trigger Options
NET GPIO Output Relay selectors:
Each client provides up to 4 relays. A variety of DASDEC II alert states can be used to trigger a relay. The
screen shot below shows the various triggering actions.
NET GPIO Input Action Options
NET GPIO Input Action selectors:
The Web Relay Dual client provides 2 inputs. A variety of actions can be triggered on the DASDEC II when a
contact closure is made on these inputs. The screen shot to the right shows the various actions. These selectors
are only available when Listen for Net GPIO Input is enabled and only for Net GPIO units that support input.
The actions can be tied to specific alert FIPS and EAS codes as well. To add FIPS code filtering, click on the
Edit FIPS button and select from the provided FIPS pool lists to create a list of triggering FIPS. See screen shot
below. Active alerts that contain ANY of the activating FIPS in a list for a specific relay, will trigger that relay
(close the contact) while the associated condition is true.
NOTE: The options for Net GPIO "During Hold of EAS until GPI closure" and "During
Audible Dubbing ..." require a Plus Package license.

4.11 Setup > GPIO: Setup General Purpose IO Options
The Setup GPIO page displays the state of the General Purpose Inputs and Outputs (GPIO) and allows programming.
GPIO is provided by connectors on the back panel of the DASDEC II. The state of the Front Panel button is included in
the GPIO table display. The state of the Internal Balanced Audio output is also displayed in the table.
Changes made to the GPIO actions/relay associations are immediate. The page updates instantly.
Auto-Refresh Timer: With the DASDEC II Plus Package license displays an Auto-Refresh Timer selector. This allows
the page to be re-displayed every 15, 30, or 60 seconds. This feature can be used to automatically view updates the
GPIO status.
There are two - or three - sections on the page to review and/or configure: DASDEC II Server GPIO Table; Programmable
GPIO; and Network GPIO Table.
1. DASDEC II Server GPIO Table
The top section of this page displays the current status of the built-in DASDEC II GPIO hardware. The top
row displays the status of the inputs. The first input is the state of the Front Panel button. This is not
available as a GPIO input but uses the internal GPIO circuitry. The next two columns show the programmed
actions and current closure state for GPIO inputs 1 and 2. The second row displays the status of the relay
outputs and of the internal audio/pass-through relay. The first two columns show the programmed triggers
and current closure state for GPIO outputs 1 and 2.
Two buttons are placed under the table for testing GPIO output relays. The first button, Close EAS Audio
Relay sends out a command to close all relays that are programmed to EAS audio. The companion button,
Open EAS Audio Relay, sends the command to open all relays that are programmed to EAS audio.
2.
Programmable GPIO Input/output Actions
Programmable options are GPIO Input 1 and 2 and GPIO Output 1 (Broadcast only) and 2 Relay. The GPIO
Output #1 relay is programmable if the broadcast option is licensed. Otherwise, it is tied to EAS broadcast
audio output and only closes during the play-out of EAS audio. It is timed such that if the video details page
is displayed by the DASDEC II, the video will be synced at the time the relay closes.
Multistation mode note: When DASDEC II multistation mode is enabled, the used physical GPIO outputs
are selectable for each station. Thus, a station can choose to NOT use a GPIO output. The station
assignment options do not allow reprogramming of a relay, just its inclusion. This allows specific GPIO
110 Digital Alert Systems: DASDEC User Manual outputs to be assigned to different stations and thereby recognized as triggering an action because a
specific station is active. Configure per station used GPIO output relays on the proper station interface
configuration page under Setup > Decoder > Forwarding.
GPIO Input 1 alert programming
A selection menu allows GPIO Input #1 to be programmed to do:
1. Nothing;
2. Forward an active unforwarded decoded alert upon closure; (Requires Plus Package license)
3. Hold a non-national alert when forwarded or originated until closure; (Requires Plus Package license)
4. Delay a non-national alert while closed.
GPI Input 2 alert programming
A selection menu allows GPIO Input #2 can be programmed to do:
1. Nothing;
2. Issue a Required Weekly Test alert (RWT). The FIPS codes used are the same as those used for the
normal One-Button test.
3. Start voice dub EAS alert on closure; subsequent closures skip to EOM. (Requires Plus Package
license)
GPIO Output 1 Relay programming (Programmability requires Plus Packagelicense)
This selection box allows for programming the GPI Output #1 closure. Set according to the condition
that needs to be monitored.
GPIO Output #1 can be programmed to make a contact closure during:
1. EAS audio play-out.
2. Momentary closure at start of EAS Audio play-out.
3. Momentary closure at end of EAS Audio play-out.
4. Momentary closure at start and end of EAS Audio play-out.
5. EAS Video play-out.

2. Momentary closure at start of EAS Audio play-out.
3. Momentary closure at end of EAS Audio play-out.
4. Momentary closure at start and end of EAS Audio play-out.
5. EAS Video play-out.
6. Main Serial Port protocol play-out of EAS.
7. While an active decoded alert that has not been forwarded (pending Manual Forward). (Requires
Plus Package license)
8. While an unforwarded active decoded alert is unacknowledged. (Requires Plus Package license)
9. Holding of an alert until GPI input 1 is closed. (Requires Plus Package license)
10. Delaying of an alert while GPI input 1 is closed.
11. Play-out of voice dub alert origination. (Requires Plus Package license)
Note: If GPIO Input 1 is programmed to hold an alert, simply changing the setting to 1, 2,
or 4 above will release the hold, and the alert will be forwarded/originated.
GPIO Output 2 Activation Filter Configurations
Choose the FIPS and EAS codes that will control which alerts trigger the applicable programmed GPIO
output 2 relay.
GPIO Pending Alert Activation Filter Configuration
NOTE: Only active with Plus Package license.
Choose FIPS and EAS codes that control which active pending alerts trigger the GPIO Output 2 for states
‘Pending manual forward of decoded EAS` or `Momentarily at start of unforwarded, decoded EAS’ or to
control which alerts are forwarded when GPIO input 1 is set to `Forward active decoded EAS upon closure’.
This interface is only present when the GPI Input #1 is programmed to Forward a pending active decoded
alert, or when the GPIO #2 output is set to close upon an active unforwarded alert. This interface allows
creation of FIPS & EAS code filtering criteria to be applied to the programmed GPI input action or to be
applied to an alert that would trigger the GPIO #2 relay closure. Use this interface to narrow down active
alerts that will be forwarded upon GPI input contact closure or to narrow which active unforwarded alerts
trigger a relay closure. The GPIO filtering criteria can be optionally overridden from the Manual Forward
Control option to allow application of the Auto-Forwarding filter to GPI triggered manual alerts under the
Setup > Decoder page. To use the interface, select the Edit FIPS and Edit EAS Codes buttons to enter
Edit mode and display the various code selection controls. All selections are active once the respective code
Editing Finished button is clicked.
With thought and careful design, GPIO relays and inputs can be used to tie the operation of the DASDEC II
into most broadcast automation systems.

4.12 Setup > Printer: Setup Printer
One of the basic tasks associated with EAS is printing logs of alert activity. The DASDEC II allows multiple means of
retrieving alert event information for printing logs. For instance, the Decoder > All Alerts and the Encoder > All Alerts
pages can be printed from a host computer to fulfill this need. Or mail delivered reports can be printed. These options
require manual intervention.
4.12.1 Connecting to a Network Computer or Via USB
To connect to a printer through USB, plug the printer into the back of the DASDEC II. From there, follow the
CUPS Printer Administration/Configuration link to the website. Click on the printers tab along the top of the
page. If the printer you have pugged in shows up on the page SET THE PRINTER AS THE DEFAULT
PRINTER. If you do not do that, it will not work. Once you have done that, print a test page to make sure it
works.
To connect to a Network computer go to Setup > Printer on the DASDEC web interface. From there, follow the
link on the page to CUPS Printer Administration/Configuration. While at the CUPS homepage, click on add
printer. Fill out the information in its entirety. You need to know the IP address of the computer on the network,
and some other information about the brand and model. The CUPS system supports many printers; it is unlikely
that you can’t find your computer to be compatible with it.
THE MOST IMPORTANT THING IS TO SET YOUR PRINTER AS THE DEFAULT PRINTER. Even if you have
only one printer added, at the end of your setup, you need to set your printer as default. This option is the way
that CUPS communicates to the DASDEC II. If you do not set the printer to default, it will not work.
There is a thorough App-note on the website about connecting your printer via Network. Go to
http://www.digitalalertsystems.com/resources_application_notes.htm. Find the App-note that pertains to
connecting your DASDEC II to a printer.

4.13 Setup > Alert Storage: Setup Storage Management Options
The Setup Storage Management Options page has three configuration options that allow custom event storage
management by timed deletion of Decoded, Forwarded, and Originated alert data.
The Setup Storage Management Options page uses an
button to submit option changes. See Chapter
3.3.4.2, How to Make Changes and Update, for details on making changes to pages with this button.
By default, all originated, decoded, and forwarded event data is configured to stay available on the DASDEC II for 365
days (unless the storage space drops below the minimum size of 100MB). Each event type, originated, decoded and
forwarded events are given a separate deletion control checkbox with a separately configurable deletion period. When
enabled, event data (sound and text files) are deleted after the user entered number of days. Timed deletion can also be
completely disabled for any of the three event types.
116 Digital Alert Systems: DASDEC User Manual Setup > Alert Storage, Setup Storage Management Options web page
Deletion of an event consists of removing audio and text data. Event header text files are always kept even when
event data is deleted. So deletion does not purge the DASDEC II of its record of a past EAS event.
Use the
button to save changes to this page.
At the bottom of the page is printed a chart of the current storage space use. The chart shows the total capacity in
Megabytes, the used space and available space in Megabytes, and the space used for specific alert event types.
Minimum space is maintained between 150 MB and 100 MB. If the DASDEC II available storage space ever drops
below 100 Megabytes, the oldest events will be chosen for automatic deletion. This pruning process is initiated after
every alert event and at midnight every night. If a minimum space condition is detected, event data is deleted until at
least 150 MB of space becomes available. The deletion time periods are also automatically adjusted downward if
needed to reflect the dates of the deleted events.

Each radio button brings up status display screens of current and expired alerts. These DASDEC II interfaces show the
active alerts and those that have expired or have been decoded, forwarded, and originated. The interfaces allow a precise
audit of current and past EAS activity.
Auto-Refresh Timer: Plus Package licensed DASDEC IIs display an Auto-Refresh Timer selector (just below and to the
left of the page title in the header section). The selector allows the page to be re-displayed every 15, 30, or 60 seconds.
Use automatic page refresh to stay informed of the DASDEC II decoding activity and decoded events status.
NOTE: All interface option changes on these pages are immediate.
5.1
Incoming Alerts
The Incoming Alerts page shows the status of Incoming and Active Decoded Alerts. Five tables on this page show the
following information: Decode Activity, Current forwarding mode, Currently Active Decoded Alerts, Alert Forwarding
Actions, and Event Storage Access.
The Incoming Alerts page is provided as a faster loading page for monitoring new and incoming EAS alert activity.
Broadcasters who are manually forwarding alerts should keep a Web browser logged on to the DASDEC II
and viewing the Incoming Alerts page with the auto-refresh option enabled.
This page has the same interfaces as the longer Incoming/Decoded Alerts page, except it does not provide the interface
for accessing expired alerts. Both pages have check boxes for optional display of the Alert Forwarding action table and
the Event Storage Access table. Features of these two tables are described below.
Under normal operation, disable the display of both of these tables to speed up the page load and refresh.
All other interfaces on this web page are described in Chapter 4.2 Incoming/Decoded Alerts.
118 Digital Alert Systems: DASDEC User Manual Decoder > Incoming Alerts web page showing optional tables
Alert Forwarding Action Table
Below the Active Decoded alerts table, the optional Alert Forwarding Action Table displays the current settings
for actions associated with forwarding the alert. The serial protocol, the Net Alert protocols, and the Analog
Audio/Video states are displayed to make it easy to know what peripheral devices will be triggered by alert
forwarding. Labels inside this table are also convenient active links directly into the correct Setup page for
changing the configuration of the associated action.
Event Storage Access table
To the right of the Alert forwarding action table is the Event Storage Access table. This table provides links to the
Decoded Files, Decoding Error Files, EAS NET Decoded Files, and post alert snapshot files. See the screenshot
below. These links will traverse a Web browser directly into the disk file storage area for decoded alerts; EAS
NET decoded alerts, and errored alerts. Traversing one of the links will place the browser page into a file view
from which all alert event files can be directly examined and downloaded. This is especially useful if an alert
could not be decoded. The WAV file saved during the decode error can be downloaded and examined or sent to
Digital Alert Systems for analysis.
Beneath the text links in the table is a toggle box Generate Decoded Event Index File. Check the toggle to
generate a monthly index file of alerts received. The index file can be used to automate queries of alert activity
via http. Index files are stored in the Decoded Files storage area and are named "events_YYYY_M(M)".
5.2
Incoming/Decoded Alerts
The Incoming/Decoded Alerts page shows the status of Incoming, Active and Expired Decoded Alerts. This page is the
primary interface for viewing current and past decoding activity on the DASDEC II. The page displays the current
forwarding mode (auto-forward or manual), current decoding activity (active alerts), the alert forwarding action table, an
event storage access table, active decoded EAS alerts, and expired decoded EAS alerts.

Decode Activity Table
The current Decode Activity table is displayed on the top left side. Each decoder channel is in a small indicator
box. The channel display has a light blue background when quiet: that is, when there is not an incoming
decoding alert. For an incoming decoding alert, the channel display box will have a red background and the
current state of the incoming decoding alert. In the screen shot below, event 4668, a Required Weekly test
(RWT), is in process of being decoded, and the full header has been received (HDR>):

Current forwarding mode (auto-forward or manual)
The top section, right side, shows the current forwarding mode (Manual or Auto-Forward). The forwarding mode
label is an active link to the Setup > Decoder > Forwarding page. When in Auto-Forward mode, alerts that
match the auto-forwarding criteria will be automatically forwarded (played). In Manual mode, no decoded alerts
will be forwarded. Active alerts will instead present a button allowing manual forward. With the Plus Package
license key unlocked, if GPI input is properly programmed, an unforwarded active alert can be forwarded via GPI
contact closure. The Plus Package license also allows Manual Forwarding to be blocked for specific alerts that
do not match the Auto-Forwarding filter criteria.
3.
Run Demo Decoded Alert
If the Demo Decode Alert mode is not enabled, go to Setup > Decode > Demo Decode / Forwarding to enable it.
This will make the ADD DEMO DECODED ALERT button pop up like in the screenshot before this.
When Demo mode is enabled, you can simulate a newly decoded alert using the Run Demo Decoded Alert
button which appears immediately below the Decode Activity Table. Pressing the button will generate an EAS
DMO type alert (Demo/Practice alert) and place it in the active decoded alert queue. This is a quick, convenient
way to test the forwarding options. The Demo alert is a real EAS alert and will have the same Manual Forwarding
and Edit/Review button options as any other decoded alert. This is especially useful for practice and training of
the Manual Forwarding options.
IMPORTANT! Forwarding a DEMO alert will take it to AIR! BE CAREFUL: Examine if AutoForward Mode is enabled before use. Make sure your EAS broadcast system is off line during
practice.
Demo alerts are set to a fixed duration of 15 minutes.
Configure Demo Decoded Alert: This text to the right of the Demo Decoded Alert button is an active hyperlink
to the Setup > Decoder > Demo/Decode Forwarding page.
120 Digital Alert Systems: DASDEC User Manual 4.
Currently Active Decoded Alerts
Currently active decoded alerts, if any, are displayed below the Decode Activity Table. The Active event list
displays all decoded EAS alerts that are currently in progress: that is, between the start and end time for the
alert. An active event remains on the active list until it reaches its expiration time, as determined by the event end
time, or until it is updated or canceled by another event of the same type and for the same area, that redefines
the event times. The decoded alerts appear in the Current Active Decoded Alerts list as long as they are current.
Active events are moved to the expired alert list as each one reaches its end time.
Active events that are forwarded (automatically or manually) display the forwarding time as an active link label to
the Decoder > Forwarded Alerts Forwarded Alerts status page. Forwarded events appear on the Forwarded
Alerts status page.
Active events that are not automatically forwarded present buttons to allow review and editing,
acknowledgment, and manual forwarding / re-enable manual forwarding. These buttons are described after
the screen shot below.
Decoder > Incoming/ Decoded Alerts web page, showing an unforwarded active alert
Acknowledge Pending Alert button
The screen shot above shows an active, unacknowledged, unforwarded alert for the active Demo alert. All
decoded alerts that have not been forwarded or acknowledged will be placed in the unacknowledged state. This

Blocked Forwarding
With a Plus Package license, the Manual Forward control selector under the Setup > Decoder > Forwarding
page allows the Auto-Forwarding filter criteria to be optionally applied to unforwarded active alerts. If this option
is selected and an alert does not pass the EAS or FIPS code filter, then the
button will be
blocked from display. It is replaced by a hyperlink message informing that manual forwarding is blocked. The link
provides a quick traversal back to the Setup > Decoder page. The application of the Auto-Forwarding blocking
criteria can be changed on the fly to re-enable the
button.

To select a date range, use the provided pull-down menu and choose a Year, Month, and Day for the FROM and
TO dates. The list will display all available data for each expired alert decoded within the selected time period.
The actual decoded headers are stored on the DASDEC II, so this information is an accurate reflection of what
the DASDEC II received. Because of its digital disk medium, a DASDEC II can archive an enormous number of
expired events. The DASDEC II will automatically remove the oldest event descriptions as needed to reserve
enough space for new alerts. However, the number of stored events is at a minimum in the thousands, so you do
not need to worry about losing track of important archived information.
Expired Alerts Display
The event status page can be printed out from the local host computers printers by using the Web browser's print
button. This makes it easy to compile FCC paper documents for EAS test accounting.
As shown in the screen shot above, every standard detail about the alert is presented in an easy to read table:
The time the alert was decoded, the time the alert was forwarded, and if it was forwarded. Forwarded alerts are
displayed on the Forwarded Event Status screen. See Chapter 5.2 Forwarded Alerts.
Audio portion
If the alert has an audio message, it can be played on the DASDEC II front panel internal speaker by clicking
that appears inside the alert entry. Or you can play the audio file on your host computer
through your web browser by clicking the text link Listen on Browser. The host computer must be configured
with a WAV file player. Alerts that did not have an audio message will not display the two audio interfaces.

detailed information relevant to the alert. TDX details must originate from the alert source.
5.2.1 Incoming & Incoming/Decoded Alerts: Multistation Mode
The active decoded alerts display supports' multistation mode. Active (enabled) stations are indicated on the
right side of the page just above the active decoded alerts table. Within the active decoded alert status a target
station ID and a
button is displayed for each enabled station. Alerts can be forwarded to any station
by simply pressing the appropriate
button. The screen shot below shows one active,
unacknowledged decoded alert, with two available enabled station targets and thus, two
buttons,
one per station. A single
and
button is provided to
cover multistation mode. Note that in multistation mode, to customize the alert audio/text translation, you must
run the Edit/Review process separately before station forwarding.
A severe EAS alert might need to be forwarded more quickly than to each enabled station in sequence.
Therefore, a separate button, labeled
, is available and can be pressed to forward the
alert to the Base station configuration. If this button is used, make sure the base station configuration will trigger
the appropriate peripheral devices and relays in order to insure that the alert is sent to all broadcasting stations.

5.3
Forwarded Alerts
The Forwarded Alerts page presents the same detailed alert information about Forwarded Alerts as the Incoming, Active
& Expired Decoded Alerts page do about decoded alerts. The pages are organized alike, without the options for the
Forwarding Action table, play audio alarm, and the Event Storage Access table. (These are unnecessary in this context).
The page displays decoding activity, forwarding mode, active forwarded alerts, expired alert views and a selected range of
expired forwarded alerts. Alert forwarding buttons are not available from active alerts shown on this page as this page
simply shows which alerts have been forwarded.
5.3.1 Forwarded Alerts: Multistation Mode
The Forwarded Alerts page indicates which alerts have been forwarded to multistation mode enabled stations.
Alerts forwarded to stations display the station ID in the event status table for each forwarded alert. The screen
shot demonstrates one Demo alert that has been forwarded sequentially to two different enabled stations.
128 Digital Alert Systems: DASDEC User Manual The next screen shot demonstrates the active Forwarded Alerts display after the same decoded alert was
forwarded to all stations (using the Forward Alert Once to All Stations button for forwarding to the base station
configuration).
The screen shot demonstrates how this alert, forwarded to the Base station, has replaced the two active alerts
forwarded earlier to the individual stations. The active alerts for the two stations are updated by this new Base
station forwarded alert and thus moved to the expired.
5.4
Originated/Forwarded Alerts
The Originated/Forwarded Alerts page displays status of all alerts "sent" from the DASDEC II. Four sections display all
scheduled originated alerts, currently active and expired originated and forwarded alerts.
Scheduled Originated Alerts
This section lists alerts which are scheduled.
Currently Active Originated/Forwarded Alerts
This section lists originated and forwarded alerts which are currently active.
Select Expired Alert View
As with the other event status views, you may choose to view Expired Alerts, Expired Alerts Pending Deletion, or Deleted
Expired Alerts. See Chapter 5.2 Incoming/Decoded Alerts, item 6 for more information about the options in this section.
Digital Alert Systems: DASDEC User Manual
129
Expired Originated/Forwarded Alerts
This section displays the total number of expired and currently active originated and forwarded alerts, and offers the same
expired alert event viewer as the other event viewers. See Chapter 5.2 Incoming/Decoded Alerts, item 7. Expired
Decoded Alerts.
Use the Date Range field to set a date range to display alerts. See Chapter 5.2 Incoming/Decoded Alerts, item 7. Expired

(originated alerts are labeled Encoded) in order to distinguish between them.
Date Range
Use this feature to set a date range to display alerts. See Chapter 5.2 Incoming/Decoded Alerts, item 7. Expired Decoded
Alerts, Set the Date Range.
130 Digital Alert Systems: DASDEC User Manual 6 Encoder
Only a DASDEC II that has been configured with a valid Encoder license key will offer the encoding (alert origination)
feature. (See Setup > Network, Chapter 4.2 Setup > Network.) Without a valid license key, the DASDEC II will not show
the main tabbed Encoder menu, nor will it display the Setup > Encoder option button under the "Setup" main tab.
The main tabbed Encoder menu has four radio buttons:
o Send Alert o Originated Alerts o Originated & Forwarded Alerts o All Alerts
Use the Encoder > Send EAS pages to originate EAS alerts. Origination is when an EAS alert is first issued from an EAS
encoder/decoder platform (compared to forwarding, which is when a decoded EAS alert is re-encoded and relayed).
EAS alert encoding is when the digital codes and alert audio tones and message defined by the EAS protocol, are
assembled and played over a broadcast medium for which EAS decoders might be listening. The DASDEC II makes EAS
encoding setup and alert origination easy, accurate, and quick. From a single, straightforward web page, EAS alerts can
be constructed and issued.
Use the other Encoder pages to view current and past originated alert events.
Due to the need for immediate action during origination, the Send EAS pages do NOT have any Accept
Changes buttons. Changes to check boxes, selection boxes, and clicking buttons on these pages are
immediate.
NOTE: Some browsers will not accept the text edit change until the mouse is clicked
outside of the field entry box. Other browsers simply will accept the change when the
Enter key is touched. You may wish to review Chapter 3.3.4.2 How to Make Changes
and Update.
6.1
Send EAS
There are some configuration tasks required on the Setup > Encoder pages before you can use the DASDEC II encoder
to originate alerts. Make sure your DASDEC II has been configured with Setup Encoder prior to attempting EAS
encoding.
In an Encoder licensed DASDEC II without Custom Messaging, selection of the Send Alert radio button displays the
Encode and Send an EAS Alert pages. This screen has two sub-page options: General Alert and One-Button Alert.
Using the One-button Alert screen is a simple way to encode and issue Required Weekly Test alerts with a single mouse
click. To encode any other alert type, use the General Alert page.
When the Custom Messaging option is licensed, a third sub-page option appears under the Send Alert pages. This is
the Custom Message page. Custom Messaging will be discussed after General and One-Button EAS.
6.1.1 General EAS
Discussion: An EAS alert always comprises a specific set of data values for encoding as Frequency Shift Keyed
(FSK) digital audio data into an audio header. This creates the characteristic EAS squawk sound that is repeated
three times at the start of an EAS alert. The data that gets placed into an EAS message is the origination code;
the EAS code type, FIPS codes, alert duration, start time, and station ID. A decoded EAS header will reveal
these values following a standard 4 letter sequence ZCZC. For example, a 30 minute Monthly test for Carson
City, Nevada starting on Jan 28 at 3:43PM from a station named DASDEC II10 would be encoded from or
decoded to ZCZC-EAS-RMT-032510+0030-0282243-DASDEC II10.
Furthermore, this information can be interpreted by the DASDEC II into a human readable form that is referred to
as the "Standard Translation". The standard translation of the above alert string is:
Digital Alert Systems: DASDEC User Manual
131
'THE BROADCAST STATION OR CABLE SYSTEM HAS ISSUED A REQUIRED MONTHLY TEST FOR THE
FOLLOWING COUNTIES/AREAS: Carson City, NV; AT 3:43 PM ON JAN 28, 2008 EFFECTIVE UNTIL 4:13
PM. MESSAGE FROM DASDEC II10. '
The translation is used for video and sign displays driven from the DASDEC II when an alert is originated or
when a decoded alert is forwarded. The translation is also prominent in the DASDEC II event status displays and
the operation log. All DASDEC II interfaces that originate and forward alert display the translation.
A Plus Package licensed DASDEC II provides user interface options to customize the alert translation. Custom
translation allows video displays driven by the DASDEC II to better describe an alert and provide more details
than actually is transmitted within the EAS protocol. Keep in mind, that custom translation only affects the video
displays. Unless TDX is used, these added text details are not sent out within the encoded EAS alert audio. A
translation can be set to substitute a user written string for the ORIG code and well as to prepend or append text
to the standard translation or even fully substitute the translation for custom text.
The General Alert web page provides a simple to use interface for setting all of these EAS data elements.
To construct and send an EAS alert, review and set items on the General Alert page corresponding to the
described EAS protocol and to the generation of local video displayed text information.
 EAS alert code
 Alert duration
 Starting time (effective time)
 Optional Origination Code Override

Station ID
This value is taken from the setup configuration for encoder Origination. It generally will not need to be changed.
If the Station ID should need to be changed, the ID label is a link to the Setup page. (Follow the provided link to
the Setup > Encoder page, Setup Encoder General Options, page. Edit as needed and then use the Back button
to return to the Encode and Send an EAS Alert page).
2.
Select Alert EAS Code
Select the EAS code from the list on the pull-down menu. Codes shown are the ones that were added to the list

link to the Setup Encoder General Options screen allows you to configure EAS Types Pool for Encoder as
needed. When finished configuring codes, use the Back button to return to the Encode and Send an EAS Alert
page to continue constructing the alert).
NOTE: Only specially configured DASDEC IIs allow origination of the National Alerts
Emergency Action Notification & Termination (EAN & EAT).
3.
Set Alert Duration
The default duration is 15 minutes. Change the alert duration as needed based upon the alert being issued. The
FCC allows alerts under an hour to be set in 15 minute increments. Alerts an hour or more in duration are set in
30 minute increments. The DASDEC II interface enforces this FCC compliance.
4.
Set Effective Start Time for alert
The default effective start time is the current Month, Day and Year followed by the current time. You can set the
effective (starting) date or time for the alert.

7.
Alert header and standard translation
Use the toggle box to view the alert header encode string and the alert translation for the currently constructed
alert. When enabled, the actual EAS encode string is displayed. Below this is the current translation. The label
above the translation will state if the translation is the basic standard translation or one with a Custom Origination
String. The label is a text link to the Setup Encoder > General Alerts screen so you can make changes as
needed.
8.
Select Video/CG/Net Translation Option (Plus Package license required)
Use the radio buttons to select either option from Standard Translation through Custom Translation Only. For
custom translations, a text entry field displays where the text can be entered.
The translation used for the local video details and the serial CG can be edited with the provided options. The
default is to use just the standard translation. Options are provided to add a custom message in front of, after, or
instead of the standard translation. Keep in mind that this custom text is NOT transmitted in the video output of
the DASDEC II.

9.
Audio Message configuration
Use the three selector interfaces (two when Required Weekly test is selected and RWT audio is disabled) to
attach pre-recorded audio voice messages to the EAS alert. Each interface permits selection of no audio file or of
an audio WAV file that has been recorded or uploaded onto the DASDEC II. Add audio files to these lists list in
two ways. You can upload WAV files using the Upload interface at the bottom of the page. Or you can directly
record audio files into the DASDEC II by using the
button at the bottom of the page. When an
audio file is selected its duration appears along with a link to load or play the file on the web browser host. At
least one of the selectors will support extra buttons to play the alert on the DASDEC II over specific DASDEC II
audio outputs (like the internal speaker or the preview outputs). The
button allows file deletion from
the audio list.
Pre-Alert Audio Announcement (optional)
Use the pull-down menu to select a pre-recorded audio file to precede the actual alert announcement.
Select Alert Audio Message (Optional)
This option is not presented for Required Weekly test (RWT) unless the Setup > Encoder > RWT audio option
is enabled. You can choose No Audio to play during the alert or an audio message from the list in the drop-down
menu.
If the TDX option is licensed, then to the right of the alert audio selection are three radio buttons: No TDX; TDX
Text; TDX URL. These control the addition of TDX alert details
Post-Alert Audio Announcement is similar to the pre-alert announcement. This option allows an audio
message to be played after the end of an EAS alert.
To change audio output levels, use the text link Goto to > Setup Audio Output Levels to link to the Setup >
Audio, Audio Output Levels/Tests page. Return using the
button.
10. Send EAS Alert, or Alert NOT Ready to Send
Once the alert is constructed correctly, the
button appears. To send, click this Button. The DASDEC
II will present a confirmation page with a review of the encoding details.
Review Prepared Alert. Examine the confirmation page prior to sending the alert. If the alert is correct, send it
by clicking the Yes, Send Alert! button. Or cancel the alert with the Cancel Alert button. If the alert send is
canceled, the DASDEC II will go back to the Encode and Send an EAS Alert page. Change the alert information
before attempting to send the alert again.
If the EAS alert data is accurate, and you are ready to issue the alert, click on the Yes, Send Alert! button. The
alert will be "originated", that is, played, out of the selected DASDEC II audio output ports. The originated alert
audio ports are selected from the Setup Audio > Encoder screens. See Chapter 4.6.3 Encoder Audio: Alert
Encoding Audio Configuration.
During the origination time, the front panel red LED will be lit, and the audio of the alert will play from the built-in
DASDEC II internal speaker. For the duration of the issued alert, the DASDEC II will periodically crawl the alert
text across the front panel LCD. The LCD text for the alert will be preceded by the letter "O", indicating a
DASDEC II originated alert. You can view the details of this alert on the screen Encoder Originated Alert Status
[Encoder > Originated Alerts].
During active alert sending, a red notice is displayed in the Send Alert interface. After the alert is sent, click the
Return or Refresh button to return back to the main Send Alert page.
If the alert is Not Ready, this message displays on the right side of this section with a reminder as to the

136 Digital Alert Systems: DASDEC User Manual 6.1.1.1 General EAS: Multistation mode
When the DASDEC II Multistation feature is licensed and at least one station is enabled, the General
Alerts page displays added options to support alert origination to individual stations. See the screen
shot below.
Encoder > Send Alert > General Alerts with Multistation options
DASDEC II Multistation operation allows EAS alerts to be originated using a specific subset of DASDEC
II controlled hardware in order to play on a specific downstream station. In this way, up to five collocated
broadcast stations or channels can use one DASDEC II for EAS alert origination.
Digital Alert Systems: DASDEC User Manual
137
The embedded EAS protocol field for the Station ID can be programmed differently for each station as
well. This makes the actual EAS alert header FSK audio (which embeds the Station ID) truly represent
the station of alert origin.
Station configuration options are performed on the Setup > Encoder > General and Setup > Decoder
> Forwarding pages.
The screen shot demonstrates the different Send EAS Alert buttons provided for station support.
Buttons are offered for all running the alert on each station in sequence, for running on individual
stations, and for running the alert once to all stations at the same time using the Base station
configuration. As in non-multistation mode, when any of the Send EAS Alert buttons are pressed, the
actual send must be confirmed on the confirmation review page.
Another difference in the Multistation mode version of the Encoder > Send Alert > General Alerts
page is the alert text translation display. The standard translation for the alert to each station is shown.
Since each station can independently set the Station ID, the Origination code, and Origination code
custom translation text, the translation text varies per station. The display shows exactly the text that is
sent per station to video character generators.
All other interface components of the Send Alert page are the same as in the non-multistation mode.
Keep in mind that the settings on this page apply to the alert (or alerts if sent to each station
sequentially) at the time the Send EAS Alert button is pressed.
Finally, the Alert Origination Action table is expanded in Multistation mode to show the actions for each
configured station. This table presents a quick view of the station by station configuration.
If all of the stations are disabled (from the Setup > Encoder > General and Setup > Decoder >
Forwarding pages) the alert origination reverts to using the Base configuration, just like a DASDEC II
that does not have Multistation operation licensed.
6.1.2 One-Button EAS
The DASDEC II supports configuration of a static set of Required Weekly test parameters on the Setup >
Encoder > Required Tests page. Once configured, the Encoder > Send Alert > One-Button Alert page
presents a single button for issuing the weekly test alert. This feature simplifies sending a weekly test alert to a
single action.
138 Digital Alert Systems: DASDEC User Manual Encoder > Send Alert > One Button Alert web page
There are two ways to send reconfigured one button test alerts. In either case, the alert is sent immediately with
the current clock time as the effective alert start time and no confirmation dialog is presented.

The header and translation toggle options and the Alert Origination Action table option works the same as on the
General EAS screen. See Chapter 5.1.1 General EAS.
6.1.2.1 One-Button Alert: Multistation mode
When the DASDEC II Multistation feature is licensed and at least one station is enabled, the One-button
EAS page displays added options to support individual station origination. See the screen shot below.

Encoder > One-Button Alert: Multistation operation
DASDEC II One-button Multistation operation allows EAS Weekly Tests to be originated using a specific
subset of DASDEC II controlled hardware in order to play on a specific downstream station. In this way,
up to five collocated broadcast stations or channels can use one DASDEC II for EAS Weekly Test
origination.
Station configuration options are performed on the Setup > Encoder > General Alert and Setup >
Decoder > Forwarding pages.
The screen shot demonstrates the different Run Weekly Test buttons provided for station support.
Buttons are offered for all running the Weekly test on each station in sequence and for running on
individual stations. As in non-multistation mode, when any of the Run Weekly Test buttons are
pressed, the test is done immediately without confirmation.
The screen shot also shows the optional alert text translation display for each station and the station
oriented Alert Origination Action Table.
140 Digital Alert Systems: DASDEC User Manual If all of the stations are disabled (from the Setup > Encoder > General Alert and Setup > Decoder >
Forwarding pages) the alert origination reverts to using the Base configuration, just like a DASDEC II
that does not have Multistation operation licensed.
6.1.3 Custom Message
The DASDEC II supports a licensed feature called Custom Messaging for playing out Civil Alert and
Administrative EAS alerts as well as non-EAS audio/video messages. This feature has extensions beyond the
EAS play-out supported under the standard Encoder > Send Alert > General Alert interface. Using Custom
Messaging, the DASDEC II can be used to broadcast custom text messages, play audio messages multiple
times, and use automatic text to speech conversion to have typed text messages automatically generate a
spoken audio track. The messages do not have to be EAS messages, which means the DASDEC II can be used
as the heart of a custom warning or information system.
Encoder > Send Alert > Custom Message
The interface shows the current status of custom messaging operation. While a custom message is being
broadcast, the interface will display message play-out status along with a Stop Active Message button. The
Stop button can pressed at any time to force an early end to the message broadcast. See the screen shot.
Digital Alert Systems: DASDEC User Manual
141
Encoder > Send Alert > Custom message; after a custom message has been sent to the DASDEC
When a custom message is active the Encoder > Originated Alerts event status page also displays the
message as an active originated event. The display includes the same force Stop Active Message button.
Decoder > Originated / Forwarded Alerts; Encoder > Custom message; after a custom message has been sent to the
DASDEC
The interface allows selection of a message type, which can be a fully custom message or either the CEM Civil
Alert EAS message or the ADR Administrative EAS message. It also allows for setting the message duration, the
message text, audio file association or text to speech audio, detailed message play-out control and a button to
start the custom message.
The advanced Message Display Control feature allows a message to be broadcast once or multiple times. Its
options provide full control over audio play-out and repeat period intervals.
When the CEM or ADR EAS message types is selected, FIPS codes and pre-alert and post-alert audio
announcements can also be configured from the interface. In addition, the EAS message types include the
option to use the standard EAS translation text in the customized text message interface.

146 Digital Alert Systems: DASDEC User Manual Typical Tasks Typical Tasks This section of the manual is intended for users that have already set up and configured their DASDEC(s) and would like to
know what to do to complete certain tasks, and also how to manage when alerts are present. When your DASDEC is up and
running, there are still things that need to be done in order to be in compliance with the rules placed on all EAS regulations.
Things like, receiving and forwarding alerts as well as keeping accurate and accessible logs of that data. This part of the
manual will step you through the process on many different tasks, and it will be able to show you what may happen, or what
should happen in the most common situations.
When Your DASDEC Receives (Decodes) an Alert
The majority of the time, when your DASDEC receives an alert, you will be forwarding it over your broadcast. But,
there are some options on what you can do before that. Below is a thorough description of those options.
When your DASDEC receives an alert, there are a few indications that will let you know. First of all, the red alert LED will
flash on the front panel of the device. The list below shows the different meanings when your alert LED is lit up:
Alert status - Red LED
 If the red LED is blinking quickly, with pauses, the DASDEC II server is decoding an incoming alert.
 If the red LED is solid, the DASDEC II is sending an EAS alert.
 If the red LED is blinking slowly and regularly, an active alert has been decoded and has not been forwarded or
acknowledged. Alerts are acknowledged by pressing the front panel button or by pushing the Acknowledge
button for the alert on the Web browser.
 If the red LED is blinking quickly and regularly, an active alert is being held pending GPI 1 input closure.
Along with those notifications that you have received an alert, the web browser interface will notify you if you are in the
Decoder > Incoming Alerts, or the Incoming/Decoded Alerts page. If you see an alert show up on the front panel, it is
recommended that you visit this page as soon as possible in order to have the most control on what happens to this alert. The
screen may look something very similar to this:
Decoder > Incoming/Decoded Alerts
This demo alert shown above is in Manual Forwarding mode, which means you physically have to forward the alert by
pressing the button on the screen. To configure or change your Auto/Manual Forwarding settings, go to Setup > Decoder >
Forwarding. From there, you can change whether or not an alert is automatically forwarded or manually forwarded based on
its FIPS location, or by what type of alert it is. It is recommended that this is configured before you receive an alert.
What now? Based on the screenshot above, there are a few things that you can do immediately after seeing that screen:
1.
Forwarding is the process of putting a decoded alert ON THE AIR. If you do not want to immediately put an alert to
air, then it is not recommended that you put your DASDEC in Auto-forwarding mode. If your DASDEC is in manual
Digital Alert Systems: DASDEC User Manual
147
forwarding mode, to simply forward that alert all you need to do is click the
button. This will
immediately put the alert on the air over what you are broadcasting. This alert can do a number of different things to
your broadcast, based on what type of alert it is and where the alert has come from.
2.
Another thing you can do as an operator is review the alert before it is forwarded over your broadcast. This can be
done by click the
show up:
button. After you press this button a screen similar to this will
On this screen, there are a few things that you can do.

First of all, on the top of the screen, just below the red decoded alert part, you can review the alert that is going
to be forwarded over the air. This shows the text that could be sent out over a crawl on your broadcast. To
listen to the audio (if there is any) look at step 3.

Just below that, you can add a custom “translation” to the decoded message. For instance, if you selected the
Forwarding Text Translation + Custom bubble, here is what would show up:
148 Digital Alert Systems: DASDEC User Manual This is an example of a message that could be forwarded along with the alert that was decoded by your
DASDEC. This option is convenient if you want to get more local and specified information out to the public.
Note: there is a maximum text size.
So, what does this option really do? Because the Forwarding Text Translation + Custom bubble is selected,
that means that when your alert is forwarded over your broadcast, it will first show the decoded message that
your received and then the custom message that you wrote. If you want your message to come first, or if you
want it to be the only message, choose one of the other two options provided.

The next section on the page allows you to put an audio file in with the decided message before it gets
forwarded. There are three options, a PRE announcement, a POST announcement and you can replace the
entire decoded alert’s audio message with your own. If you want to listen to the alert message, go to step 3 of
this section. This is pretty self-explanatory, the pre-announcement will go before the decoded audio, and the
post-announcement will go after the decoded audio if selected.
Where do these audio files come from? There are a few things you can do to get an audio file.
1. If you have some pre-loaded audio files uploaded, then you can select from the pool on the right as your
options.
2. If you want to upload an audio file to use, use the purple field at the bottom to locate that file on your
computer and upload it to the pool on the right. Note: this audio file has to be in a .wav format. For the
steps on uploading an audio file, see the section of the operator’s manual that explains that.
3.
Lastly you can click the
button, which will take you to a page that looks like this:
From there, you can record a specific audio file (This is good if you want to get a message across to the public
in a pinch). Provide it with an Audio Filename BEFORE you start recording, and then it will show up on the
pool on the right when you go back to the previous editing page.
3.
The third you thing you can do is listen to the audio that was sent with the decoded alert. You can do this by clicking
on the
button or hyperlink. The Play -> Front panel button will play the audio on the front
panel of the DASDEC. This option DOES NOT play the message over your broadcast; it only plays it on the front
panel so you can hear it. The listen on browser hyperlink takes you to a new page that plays the message on your
internet browser. Just use the back button on your browser to get back to the DASDEC interface.

Originating/Encoding an Alert
Originating and Encoding mean the same thing; it is the creation of an alert that can be forwarded over your own broadcast.
When this alert is forwarded over your broadcast, any station that is tuning into your station will receive and decode that alert
in that station’s own EAS device. Simply, any station that is listening to your station on their EAS device will receive and
decode the alert that you sent out, just like if you were to receive an alert from another station over your radio tuners. This is a
useful tool for making custom alerts and putting them on your own broadcast.
Here is the way to configure your Encoder in order to be able to send out an originated alert that is applicable to any situation:
1. Go to Setup > Encoder > General
2. Select your ORG Code, which is at the top of the page.
3. Type in the name of your station in the EAS Station ID text box (For example; WKDQ/FM)
4. Set your Non-national alert play scheduling to be what you want. For example, as soon as possible means if
there is another alert in process when you send out an originated alert, it will play as soon as possible after the
alert that is in process is done.
5. Set your Attention Signal Duration (8 seconds is fine, unless you want more)
6. Enable Weekly Test Audio if you want audio in your weekly test by clicking on the check box, putting a little
green check mark in the box. (If you are a radio broadcaster, you should enable this)
7. Jump down to the Configure Available EAS Types for Encoder Alert Origination Interfaces section. In order
for you alert to be whatever type of alert you want, I suggest selecting all of the EAS Types and adding them to
the pool on the right. This can be made easy but clicking and holding the top option, and then pulling your mouse
down to the bottom of the table until all of the options are selected.
8. Move down to the Configure Available FIPS for Encoder Alert Origination Interfaces. For this option, you may
want to select the counties that are around your county (including your own county) or you can select all of the
counties in your state for use in later originated alerts. NOTE: By selecting your entire State FIPS Code, it will
send to all of the counties in your state, where as if you choose every county individually, you can customize
your encoded alert to go to specific counties. It is recommended that you select all of the counties individually
and also include your entire State FIPS code.
Now that your general Originated/Encoded alerts is set up we can configure different types of alerts.
What type of alert am I sending out? Well, there are a couple different alerts you can send out, and a few different ways
to go about it. Here are a few options:
1. Required Weekly Test
One thing that is required by the FCC is that your station sends out a weekly test. The DASDEC makes this process
very easy, and in most cases “hands free” because it can be set to do it automatically within a specified time during
the day/night.
To configure the Automatic Weekly test, follow these steps:
1. Go to Setup > Encoder > Required Tests
2. Enable Automatic Random Required Weekly Test Generation by clicking on the check box. It will say
ENABLED when it is enabled. Note: If you do not want an automatic weekly test generation, then do not check
this box. By not checking that box, it means that if you want to send out a weekly test, you will have to send one
out manually every week.
3. After that box has been checked, a new set of options will appear. These options apply to the timing of the
automatic random weekly test generator. You can set the alert to forward during whatever hours you want, and
on specific days that you want. Note: If you don’t want the random RWT to interrupt your daily broadcast
programming, set the test to forward between something like 2 A.M. and 4 A.M. This time option is based on a
24 hr. clock.
4. Jump down to Configure One-Button and Automatic Weekly Test, and take a look at the options. You can
select the FIPS codes you will forward to, select the audio that is associated with your originated alert, and
change the length of time that your originated alert will be. It is recommended that you at least include your own
county in your required weekly test FIPS selection. To do this, just select your county and then click on the Add
Selected FIPS button. Also, configure your pre-announcement, announcement and your post-announcement
(you don’t need a pre or post announcement or any announcement at all. But, if you have an announcement
uploaded, you can use it here.)
150 Digital Alert Systems: DASDEC User Manual 5. At the bottom of the page, you can choose from some further options that will regulate your RWT. The first option
Include qualified forwarded alerts for blocking creation of Random Weekly Tests, instead of just qualified
originated alerts could be important. This option, when enabled, does not schedule a weekly test if your station
has forwarded a weekly test that was decoded from another station. You can choose what you want to do with
this option. If you have set up your decoder to NOT forward weekly and monthly tests automatically, then do not
enable this option. Conversely, if you have set up your decoder settings to forward weekly and monthly tests
automatically, you might want to enable this option.
Here is a screenshot of a configured One-button and Automatic RWT generation page:
Now that you have set that all up, you can either wait for your DASDEC to pick a time to forward an RWT (within
your specified time) or, you can go to Encoder > One-Button Alert and press on the big button to forward the
RWT over your broadcast when you want to. I would recommend letting your DASDEC do the planning for you,
even though pressing that big button is tempting.

2. Originating an Emergency Alert
In the beginning of the section, you configured your settings for setting up a general Encoded Emergency Alert. So
this will be pretty simple.
To create an originated alert to forward over your broadcast, go to Encoder > Send Alert > General Alerts and
configure the options to how you want your alert to look. The options are put into six steps for you. An example of
setting up an alert is shown below in a screenshot:
To forward the alert over your broadcast, click on Send Alert, and then you will be sent to a confirmation page.
Confirm the alert, and it will be sent out over your broadcast.
152 Digital Alert Systems: DASDEC User Manual Retrieving the Logged Alerts in your DASDEC
Steps to Viewing/Downloading/Printing your DASDEC’s logged alerts:
1. Go to Decoder > All alerts in the DASDEC Online interface. It should look something like this:
By the way, your DASDEC saves all of your Encoded, Decoded and Forwarded alert information automatically.
2.
3.
In the yellow box on the screen shot, you want to select the amount of time you want to look back when you view
your alerts. So if the FCC says “We want the alerts from the past month” then select the option that shows them the
alerts from the past month.
The big red arrow in the screenshot points to a hyperlink that says Click for text version. This is the key to
retrieving, downloading and printing your alerts.
a. To view your alerts, simply click on the hyperlink. This will take your web browser to a new page that shows
you all of the alerts that apply to the selected time you chose. If you want to go back, just use the back
button in your web browser. You can print this by then proceeding to press Ctrl + P on your keyboard, and
proceed with the printing options.
b. To download your alerts, right click on the hyperlink. In the right click options, you will be given the choice to
pick “Save link as…” From there, you can save the .txt (text file) file anywhere on your computer. This file
can be opened by a simple text file viewer. This can also be printed from the text file.
c.
Lastly, you can just print the logs by clicking on the
button next to the hyperlink. If you have a default
printer configured to your DASDEC, then clicking on this button will automatically begin printing all of the
alerts in the selected amount of time that you chose.
That’s basically it. There is an advanced option next to the print button that organizes your printout in groups of forwarded,
decoded and encoded alerts instead of it all being in order by the date, but you don’t need to enable that in order to print out
your reports.

The Emergency Alert System
Purpose
According to the FCC, "The EAS is designed to provide the President with a means to address the American people in the
event of a national emergency. Through the EAS, the President would have access to thousands of broadcast stations,
cable systems and participating satellite programmers to transmit a message to the public. The EAS and its predecessors,
CONELRAD and the Emergency Broadcast System (EBS), have never been activated for this purpose. But beginning in
1963, the President permitted state and local level emergency information to be transmitted using the EBS."
However, the EAS system is used for much more than to support a method of communication that has never been (and
hopefully never will be) used. The EAS system provides state and local officials with a method to quickly send out
important local emergency information targeted to a specific area. This includes weather alerts as well as local emergency
Digital Alert Systems: DASDEC User Manual
157
alerts such as child abductions and disasters. The EAS system also runs test alerts on a weekly and monthly basis in
order to insure operability.
Operation
The EAS system digitally encodes data into audible audio to order to distribute messages. This information can be sent
out through a broadcast station and cable system. The EAS digital signal uses the same encoding employed by the
National Weather Service (NWS) for weather alerts broadcast over NOAA Weather Radio (NWR). Broadcasters and cable
operators can decode NWR alerts and then retransmit NWS weather warning messages almost immediately to their
audiences. With the proper equipment and setup, EAS alerts can be handled automatically, making EAS information
useful for unattended stations. Other specially equipped consumer products, built into some televisions, radios, pagers
and other devices, can decode user selectable EAS messages.
The DASDEC II is designed to facilitate the management side of encoding and decoding EAS alerts within cable and
broadcast facilities. It is especially easy to use since it is IP addressable and accessible over a LAN.
Management
The FCC designed the EAS system, working in cooperation with the broadcast, cable, emergency management, alerting
equipment industry, the National Weather Service (NWS) and the Federal Emergency Management Administration
(FEMA).
The FCC provides information to broadcasters, cable system operators, and other participants in the EAS regarding the
requirements of this emergency system. Additionally, the FCC ensures that EAS state and local plans developed by
industry conform to the FCC EAS rules and regulations and enhance the national level EAS structure.
NWS provides emergency weather information used to alert the public of dangerous conditions. Over seventy percent of
all EAS and EBS activations were a result of natural disasters and were weather related. Linking NOAA Weather Radio
digital signaling with the EAS digital signaling will help NWS save lives by reaching more people with timely, site-specific
weather warnings.
FEMA provides direction for state and local emergency planning officials to plan and implement their roles in the EAS.
What you need to do as a Broadcaster
Your DASDEC II encoder/decoder allows your facility to decode EAS alerts originated from alert sources in your area.
These sources can be radio, TV, and cable TV stations. These stations can be forwarding alerts received from a web of
broadcasters, or originating alerts if designated as a primary source. To meet minimum requirements of the FCC, you
must send randomized weekly tests, forward monthly tests, and forward National alerts. Your state and local EAS
plan may also impose other requirements.
A good source of information is the EAS website at http://www.fcc.gov/eb/eas/. The FCC provides handbooks in Adobe
PDF format for AM and FM radio, for TV and for Cable TV.
DASDEC II Peripherals
The DASDEC II supports many peripheral devices, from character generators to printers. As of this release, the DASDEC
II can replace most commercial EAS encoder/decoder units, depending upon the peripheral hardware to which they have
been connected.
158 Digital Alert Systems: DASDEC User Manual Vela NDU
The Vela NDU 710 is a sophisticated character generator controller and general messaging system from Vela Broadcast.
It comes with a complete EAS management system that controls a TFT-911 EAS encoder/decoder. The DASDEC II can
replace a TFT-911 in this system. It can be connected via a Null modem cable from the NDU serial port to the DASDEC II
serial port. The DASDEC II alert audio output must be wired to the selected NDU audio input port. The DASDEC II CG
setting must be set to TFT. After that, the NDU will run normally without further configuration. For details on the Vela NDU
701, refer to the literature at www.vela.com.
Monroe Electronics Cable Envoy and CEMS 500/1000
The DASDEC II directly supports Monroe Electronics Cable Envoy multi-channel analog video CG and the CEMS
0500/1000 single channel analog video crawl overlay keyer. The Cable Envoy interacts with and acts as a controller for
the DASDEC II. For instance, it controls running audio from the DASDEC II. The CEMS unit is a basic CG to which the
DASDEC II can send text crawl commands. Both Monroe units require a straight through RS-232 cable. The Monroe
CEMS requires a DASDEC II TV license. See EAS equipment at www.monroe-electronics.com.
NOTE: Monroe Electronics manufactures the DASDEC II under license and markets it

The DASDEC II directly supports the single channel analog Keywest Technology VDS-830 and 840 character generator
units. These units require a NULL modem RS-232 cable. The DASDEC II can crawl alert text on the VDS as well as
provide severity color coded backgrounds. The VDS-830 cannot key the crawl over a video background. It will replace the
full page with a gray background. The VDS-840 can key the crawling text over live video. The DASDEC II also has modes
to support the Starmu and Star-8 CG's. This option requires a DASDEC II TV license. See www.keywesttechnology.com.
Chyron CODI
The DASDEC II can replace systems that operate Chyron CODI character generators. The DASDEC II supports both the
analog CODI as well as the Digibox CODI. The DASDEC II can crawl alert text overplayed on live video on these units.
The Digibox CODI provides SDI digital video input and output. The DASDEC II also supports simultaneous network based
control of multiple CODI Digibox units that provide a built-in LAN port. This option requires a DASDEC II TV and Plus
Package license. See www.chyron.com.
Evertz Keyers
Evertz Logo Insertors, Media Keyers, and other digital and analog Evertz character generators are supported by the
DASDEC II using the SAGE generic CG protocol. The Evertz unit must support an EAS option and be pre-programmed to
recognize EAS communication on the specific com port being used. For digital operation the DASDEC II must be
equipped with an optional AES audio output or the DASDEC II Analog audio needs to be encoded into AES digital audio
with an A to D converter. The GPI EAS Audio output of the DASDEC II is used as an input to trigger voice-over activation
on the Evertz unit. The Evertz units handle all switching between normal program video/audio to EAS play-out. The
DASDEC II offers manual alert forwarding notification with GPI output relay indication of pending alerts. This allows EAS
to be forwarded when appropriate, either manually by an operator or by automation. See the diagram below.
NOTE: Two Evertz keyers can be run from one serial port output wired in parallel to two ports.

The directions provided by Evertz for the SAGE generic protocol has been tested by Evertz and will work with the
DASDEC II. See www.evertz.com.
XBOB CG
As of version 1.6-0, the DASDEC II supports the low cost XBOB character generator. The DASDEC II can generate a
crawl on a single video channel that is passed through an XBOB. This option requires a DASDEC II TV license.
BetaBrite LED sign
The DASDEC II supports driving the wide range of BetaBrite LED signs from a DASDEC II serial port. A special cable is
usually needed to connect the DASDEC II RS232 serial ports to a BetaBrite. The Betabrite protocol on the DASDEC II
supports running EAS alert text crawls immediately upon decoding as well as during alert origination and forwarding.
Other Character Generators
Any character generator or turnkey system that can operate the standard TFT 911 EAS serial control protocol or supports
the SAGE Generic protocol can interface to a DASDEC II. A Null modem cable from the CG serial port must be connected
to the DASDEC II serial port for TFT emulation. The serial cable required for units using the SAGE Generic CG protocol
depends on the unit.
Character generators that can be run from the SAGE generic CG protocol include Evertz Keyers and Miranda ImageStore
units. Also, for Miranda interfacing, refer to the diagram above for Digital CG.

Interfacing to a TV system with Utah Scientific SqueezeMax HD system with Utah Scientific 2020 switcher,
downstream mode.
The DASDEC II can interface to multiple SqueezeMax units using the LAN based EAS NET protocol, but the alert must be
played on all SqueezeMax units at the same time. EAS NET sends alert text to each interfaced SqueezeMax unit and
then goes into a pending alert play-out state. The text alert sent to the SqueezeMax places it into a pending EAS play-out
mode. The EAS crawl can then be triggered manually on the SqueezeMax via 2020 Master Control switcher when desired
(within a few minutes). Master Control supports this action via a custom macro, associated with a panel button, which
triggers the SqueezeMax EAS preset, switches audio output to the DASDEC II input, and produces a GPI contact closure
for triggering alert play-out on the DASDEC II. The DASDEC II goes out of pending alert mode and plays the alert audio
until finished. When the alert is finished, SqueezeMax is taken out of EAS display and Master Control returns audio back
to normal program audio.
The DASDEC II can also be directly connected to a single SqueezeMax using a serial connection.

Refer to description above for the SqueezeMax. A DASDEC II can interface to mixed SD and HD SqueezeMax units, but
as described above, the alert must be played on all units at the same time.

162 Digital Alert Systems: DASDEC User Manual EAS Protocol
The DASDEC II encodes the EAS messages per FCC rules for the EAS protocol. The EAS protocol from the FCC is described
as follows (printed directly from the FCC ruling).
The EAS uses a four-part message for an emergency activation of the EAS. The four parts are; Preamble and EAS Header
Codes, audio Attention Signal, message, and, Preamble and EAS End Of Message Codes.
The Preamble and EAS Codes must use Audio Frequency Shift Keying at a rate of 520.83 bits per second to transmit the
codes. Mark frequency is 2083.3 Hz and space frequency is 1562.5 Hz. Mark and space time must be 1.92 milliseconds.
Characters are ASCII seven bit characters as defined in ANSI X3.4-1977 ending with an eighth null bit (either 1 or 0) to
constitute a full eight-bit byte.
The Attention Signal must be made up of the fundamental frequencies of 853 and 960 Hz. The two tones must be transmitted
simultaneously. The Attention Signal must be transmitted after the EAS header codes.
The message may be audio, video or text.
The ASCII dash and plus symbols are required and may not be used for any other purpose. Unused characters must be ASCII
space characters. FM or TV call signs must use a slash ASCII character number 47 (/) in lieu of a dash.
The EAS protocol, including any codes, must not be amended, extended or abridged without FCC authorization. The EAS
protocol and message format are specified in the following representation. Examples are provided in FCC Public Notices.

End Of Message code.
ZCZC- This is the identifier, sent as ASCII characters ZCZC to indicate the start of ASCII code.
ORG- This is the Originator code and indicates who originally initiated the activation of the EAS. These codes are specified in
paragraph (d) of this section.
EEE- This is the Event code and indicates the nature of the EAS activation. The codes are specified in paragraph (e) of this
section. The Event codes must be compatible with the codes used by the NWS Weather Radio Specific Area Message
Encoder (WRSAME).
PSSCCC- This is the Location code and indicates the geographic area affected by the EAS alert. There may be 31 Location
codes in an EAS alert. The Location code uses the Federal Information Processing Standard (FIPS) numbers as described by
the U.S. Department of Commerce in National Institute of Standards and Technology publication FIPS PUB 6-4. Each state is
assigned an SS number as specified in paragraph (f) of this section. Each county and some cities are assigned a CCC
number. A CCC number of 000 refers to an entire State or Territory. P defines county subdivisions as follows: 0 = all or an
unspecified portion of a county, 1 = Northwest, 2 = North, 3 = Northeast, 4 = West, 5 = Central, 6 = East, 7 = Southwest, 8 =
South, 9 = Southeast. Other numbers may be designated later for special applications. The use of county subdivisions will
probably be rare and generally for oddly shaped or unusually large counties. Any subdivisions must be defined and agreed to
by the local officials prior to use.
