Introduction
About this Manual
This manual contains information about the Extron IPL T SF24
(Extron part #60-544-02) and the IPL T SFI244 (Extron part
#60-544-06) Ethernet control interfaces. It includes information
on how to install, configure, and operate each system. When
information in this manual applies to both models, they may be
referred to generally as an IPL T SF unit or interface.
About the IPL T SF Interfaces
The Extron IPL T SF interfaces (SF24 and SFI244) are Ethernetbased control interfaces designed to be used as one of many
nodes in a distributed control system environment, or as standalone control interfaces allowing legacy products to link to
today’s IP Link® -based networks.
The IPL T SF24 has two serial ports and four flex I/O ports.
Each serial port is available on both 9-pin D and captive screw
connectors. The 9-pin D connectors support RS-232, RS-422,
and RS-485. The captive screw connectors support RS-232 only.
The four flex I/O ports are on a 5-pole captive screw connector
which provides one pole for each port, as well as a fifth for
ground. All serial ports are fully software configurable through
the network using either the Web-based interface or a Telnet
connection.
The IPL T SFI244 has one 10-pole, 3.5 captive-screw connector
for the two bidirectional COM ports and the four digital I/O
ports. It also has one 8-pole, 3.5 captive-screw connector for the
four IR output ports. The ports are fully software configurable
via the 10/100 Ethernet port using a Web-based interface. The
IPL T SFI244 only supports the RS-232 protocol (RS-422 and
RS-485 protocols are not supported). The IR ports are capable of
transmitting both carrier and non-carrier (wired or IR) control
data.
N The 5-pole captive screw serial ports support only RS-232.
The IPL T SF interfaces can host their own Web pages, stored
in flash memory within the devices. They will support
Telnet, SMTP (simple mail transfer protocol), ICMP (Internet
control message protocol) or ping, and DHCP (dynamic host
configuration protocol).
The IPL T SF interfaces are 1U high and one quarter rack wide.
They are rack-mountable, using either a VersaTools® Rack
Shelf Kit (Extron part #60-190-20) or a Universal 1U Rack Shelf
(Extron part #60-190-01). They can also be mounted under a
desk or podium, or on a projector mount.

UL guidelines for rack mounting
The following Underwriters Laboratories (UL) guidelines
pertain to the installation of an IPL T SF Series unit onto a rack.
2-2
1.
Elevated operating ambient — If installed in a closed
or multi-unit rack assembly, the operating ambient
temperature of the rack environment may be greater
than room ambient. Therefore, consider installing
the equipment in an environment compatible with
the maximum ambient temperature specified by the
manufacturer [Tma = +32 to +122 °F (0 to +50 °C)].
2.
Reduced air flow — Installation of the equipment in a rack
should be such that the amount of air flow required for
safe operation of the equipment is not compromised.
3.
Mechanical loading — Mounting of the equipment in
the rack should be such that a hazardous condition is not
achieved due to uneven mechanical loading.
4.
Circuit overloading — Consideration should be given to
the connection of the equipment to the supply circuit and
the effect that overloading of the circuits might have on
overcurrent protection and supply wiring. Appropriate
consideration of equipment nameplate ratings should be
used when addressing this concern.
IPL T SF Series • Installation and Operation
5.
Reliable earthing (grounding) — Reliable earthing
of rack-mounted equipment should be maintained.
Particular attention should be given to supply connections
other than direct connections to the branch circuit (such as
the use of power strips).

IPL T SF Series • Connection and Configuration
Configuring the Hardware
To function together properly, both the controlling PC and the
IPL T SF interfaces must be configured correctly: the PC must
be network-capable, with the proper protocols installed and the
hardware configured correctly, and the interface must be set to
recognize and accept commands and pass them through to the
switcher, projector, or other controlled device.
PC configuration
This manual assumes that you have a Windows® PC equipped
with an operating network adapter. To allow your PC to work
with Extron’s Ethernet-controlled products, the TCP/IP protocol
must be installed and properly configured.
For use on an existing Ethernet LAN intranet, your network
administrator can provide you with a unique IP address or
confirm whether you need to set up the IPL T SF unit for DHCP
(Dynamic Host Configuration Protocol) to have an address
assigned automatically when you sign on.
Initial start up
When you power on the IPL T SF interface for the first time,
there are two ways to set up the IP address:
1. Use the ARP command method.
2. Use the direct PC method.
The default Web pages that are pre-loaded on the IPL T SF
interface provide a way to reconfigure the IPL T SF unit once
it has an active network connection with IP access. These Web
pages are compatible with Netscape® Navigator® (version
6.0 or higher), or Internet Explorer® (version 5.5 or higher).
See “Communication with the Interface” in chapter 4 for
information on accessing and configuring the interface.
Once the interface has been reconfigured, an Ethernet (intranet
or Internet) connection can subsequently be used to contact or
control it. Refer to “Ethernet connection” in this chapter for
additional information.
IPL T SF interface configuration
Configuring the IPL T SF using the ARP command
You can make use of the ARP (Address Resolution Protocol)
command to set up an IP address for your IPL T SF interface.
The ARP command tells your computer to associate the
IPL T SF unit’s MAC address with the assigned IP address. You
must then use ping to access the IPL T SF unit, at which point
the device server’s IP address will be reconfigured.
IPL T SF Series • Connection and Configuration
3-5
Connection and Configuration, cont’d
N In order to use this setup method, both your computer and
IPL T SF interface must be connected to the same LAN.
Or, you may use a crossover Ethernet cable to connect the
device server directly to your computer’s Ethernet card.
Use ARP to configure the IP address as follows:
1. Obtain a valid IP address for your IPL T SF interface from
your network administrator.
2. Obtain the IPL T SF unit’s MAC address (UID #) from the
label on its rear panel.
3. If the unit has never been configured and is still set for
factory defaults, go to step 4. If not, perform a Mode 4
system reset. For detailed information on reset modes, see
“Resetting the unit” in Chapter 2.
C Your IPL T SF unit must be configured with the
factory default IP address — 192.168.254.254 —
before executing the ARP command, as described
below.
4. Access the MS-DOS command prompt, then execute the
‘arp –s’ command.
Enter the desired new IP address and the MAC address
(the MAC address is located on the rear panel’s upper
right corner) for the IPL T SF unit. For example:
arp –s 10.13.170.15 00-05-A6-00-0A-90
Figure 3-5 — Executing the ARP command
3-6
5. Execute a “ping” command by typing your new IP address
at the command prompt. For example:
ping 10.13.170.15
After issuing this command, the unit changes to the
new address and start responding to the ping requests,
as shown below. The IPL T SF unit’s IP address should
IPL T SF Series • Connection and Configuration
now be updated to the new address, and then you can
reconnect using either Telnet or the Web to verify that the
update was successful.
Figure 3-6 — Unit response to a ping request
6.
After verifying that the change was successful, issue the
arp –d command at the DOS prompt. For example:
arp –d 10.13.170.15 removes 10.13.170.15 from the arp table
or
arp –d* will remove all static IP addresses from the arp
table.
Configuring the IPL T SF using direct PC connection
This type of connection is used initially to connect to and
configure the IPL T SF unit. The unit’s default settings (IP
address, subnet mask, and [optional] administrator name and
password) must be changed in order to use the unit on an
intranet (LAN) or on the Internet (WAN).
1.
Plug one end of a CAT 5, crossover Ethernet cable into
the rear panel Ethernet connector on the IPL T SF unit.
See figure 2-7 for RJ-45 connector wiring.
2.
Plug the other end of the Ethernet cable into the Ethernet
port on your PC.
3.

Ports Overview
Flex I/O ports
Extron flex I/O ports are configurable input or output ports
designed to provide connectivity to various devices such as
motion detectors, alarms, lights, LEDs, buttons, photo (light)
sensors, temperature sensors, relays, etc. All flex I/O ports are
tied to a common ground, but can be individually configured to
operate in one of three different modes:
•Digital Input
•Digital Output
•Analog Input
These ports can be configured by using the default Web pages
of the IPL T SF Web Server (see figure 4-1 below; also see
“Establishing or changing system or port settings” later in this
chapter) or by dynamically using the Simple Instruction Set™
commands (see the “Programmer’s Guide for the Telnet and
Web Browser” in this chapter) via Telnet, scripts or Web pages.
Figure 4-1 — Default Web page for flex I/O
Digital input
When a flex I/O port is configured as a digital input, the port
is set to measure two states: 1 or 0; On or Off; high or low. A
closed circuit = a logic 1 and an open circuit = a logic 0.

The ability to turn on an internal pull-up resistor to
+5 VDC (shown below as SW2)
2.
Adjustable detection threshold voltages
The default threshold voltages follow standard TTL logic:
a voltage below 0.8 VDC is measured as logic low, and a voltage
above 2.0 VDC is measured as logic high. Using an adjustable
threshold, the integrator can select the proper high and low
voltages for the installation.

If the integrator selects threshold voltages that are more than
0.1 V apart, a deadband, or hysteresis, will be established.
In the example below, the lower threshold voltage is set at
+6 VDC and the upper threshold is set at +16 VDC. The colored
bands show state changes on the logical outputs.
The range between 6-16 VDC is the deadband in which the
signal can fluctuate without affecting the input state.

Digital output
When a flex I/O port is configured as a digital output, it is set
to offer two output states: “on” and “off”. When the port is
set to an “on” state, (SW1 is closed), the I/O pin is connected
to ground (each I/O port is capable of sinking 250 mA max.).
When the port is set to the “off” state, (SW1 is open), the output
pin is floating.
If the application calls for TTL compatibility, SW2 can be
selected to provide a 2K pull-up resistor to +5 VDC.

Bidirectional serial control interface ports
The IP Link® family of products has several models that
incorporate bidirectional serial control ports. The serial ports
allow for control of a wide variety of existing Extron and thirdparty devices. The most common serial control formats are
RS-232, RS-422, and RS-485. Within the IPL T SF products, there
are two different implementations for the serial control ports:
the 9-pin D connector and the captive screw connector.
9-pin D Connectors — On some IPL T SF units, serial control
is accessed through a 9-pin D connector. In this
configuration, all three control formats are available and
fully software configurable. By selecting the
RS-232 format, hardware handshaking (RTS, CTS) is also
available. The RS-232 connection uses the same industry
standard interface pin-out as found on standard PCs. If
selecting either RS-422 or RS-485 formats, verify proper
wiring as detailed in figure 2-8. These two formats do
not have an industry standard pin-out and will vary from
device to device.
Captive Screw Connectors — On other IPL T SF units, several
of the serial interface ports are connected on captive
screw terminals. When using the ports on the captive
screw terminals, only RS-232 control is available, and
hardware handshaking is unavailable. Since RS-232 is
the most common control interface encountered, this port
configuration allows for quick termination.
IPL T SF Series • Communication and Control
4-5
Communication and Control, cont’d
N Pacing and handshaking are not supported on captive
screw connectors.
All of the bidirectional serial ports are completely software
configurable. Baud rates can be set up to 115 Kbs. Using
the Simple Instruction Set (SIS) commands found in the
“Programmer’s Guide for the Telnet and Web Browser” later in
this chapter, these ports can be configured to control most serial
devices. Once a port is configured and properly cabled to the
controlled device, serial commands can be issued to the port
from a Web page, Telnet connection, or by using the advanced
scripting capability built into the IP Link product family.
Communication with the Interface
Web server
The on-board Web server is displayed as a set of default Web
pages which can be accessed via a Web browser. These pages
are the primary means of communication with, and control
through, the IPL T SF interface. Web browsers such as Netscape
Navigator (version 6.0 or higher), or Internet Explorer (version
5.5 or higher) can be used, but if using Internet Explorer, you
must also have Microsoft Script (version 5.6 or higher).
The PC used to access the Web server must have a connection in
common with the IPL T SF interface. In other words, both the
unit and the PC should be connected to your local intranet or
the Internet.
If you have established passwords for the interface, you will be
shown a password window when your browser accesses the
IPL T SF unit (but not when you initially access the Web server,
since no passwords have been established). Your level of control
over the interface depends on the password you enter in this
password screen. If you enter the administrator’s password, you
have control of all matters of configuration. If you enter a user
password, you are be restricted to control of A/V devices and
viewing status.

N Due to the 7 character limit for full file names, it’s advised
that you use numeric titles (e.g., 1.eml, 24.eml). Numeric
titles reduce the characters of the file name, and assist in
keeping the alert files organized. However, alphabetical
titles are permitted.
To finalize your new e-mail alerts within the Web server, do the
following:
6.
Obtain your gateway IP address from your system
administrator.
7. Click System Settings on the menu on the left side of the
window.
8.

gateway IP address into the Gateway IP Address field.
Sending an e-mail alert through Telnet
To complete the process of sending an e-mail alert, you must
send it through a Telnet session and receive confirmation. To do
so:
1.
Open a Telnet session. For instructions on how to do this,
see “Accessing and using Telnet” later in this chapter.
2.
Use the “Send e-mail” SIS command to send the alert to
the e-mail address of a numeric mailbox (see figure 4-14).
Refer to the “Programmer’s Guide for the Telnet and Web
Browser” later in this chapter for specific command code.
For example, the code for sending an alert from the 4th numeric
mailbox would be

Creating a driver with the IR Learner software
In order to use your third-party remote device with the
IPL T SFI244, the functions of your third–party driver must be
“learned” by the IPL T SF unit. In other words, you must create
a driver for your remote control device. You have the option
of creating a new, custom driver or manipulating an existing
driver. Both can be accessed or created through the IR Learner
software.
To create a driver for your remote control device:
1. Launch the IR Learner software application. The
application window appears; there are no open drivers.
2.
Create a new or empty driver by selecting File > New. A
driver document is created, and its Header tab is selected.
Figure 4-18 — Creating a new driver
3.
Edit the Header fields (figure 4-18), the most important
of which is Type. The driver is populated with a default
set of commands according to the selected device type. A
device type of “Other” creates an empty driver with no
functions.
4. Add functions by pressing the Add button in the toolbar.
N User-definable functions may be added to the driver. The
names and ordering of user-definable functions may be
changed at any time by double-clicking on the function
to be renamed. The names and ordering of any default
functions cannot be altered.

figure 4-19). Then begin a learning session by pressing the
Learn toolbar button. A series of messages and windows
will guide you through the “learn” process, providing
instruction on how to aim the remote, what button to press
and when to release the button.

practice, be the full URL of the control interface and Web page
reference including all path information
(e.g., http://192.168.100.10/myform.htm).
To send any of the commands using a Web browser you need
to prefix them with the full URL followed by ?cmd= (See “URL
Encoding” later in this chapter).
N With Telnet you can use either the “Escape” commands
or the “W” commands, and the carriage return or the pipe
character. With the Web browser, you are required to use
the “W” commands and the pipe character.
In either method {Data} = Data will be directed to a specified

IPL T SF Series • Communication and Control
Password information
The “]Password:” prompt requires a password (administrator
level or user level) followed by a carriage return. The prompt is
repeated if the correct password is not entered.
If the correct password is entered, the unit responds with “]
Login Administrator]” or “]Login User]”, depending
on the password entered. If passwords are the same for both
administrator and user, the unit defaults to administrator
privileges.
Error responses
When the IPL T SF interface receives a valid command, it
executes the command and sends a response to the host
device. If the unit is unable to execute the command because
the command contains invalid parameters, it returns an error
response to the host.
E10 — Invalid command
E12 — Invalid port number
E13 — Invalid parameter
E14 — Not valid for this configuration
E17 — System timed out
E22 — Busy
E24 — Privilege violation
E25 — Device not present
E26 — Maximum number of connections exceeded
E27 — Invalid event number
E28 — Bad filename/file not found
References to errors (at command descriptions on the
following pages):
10
= Commands that give E10 (Invalid command).
24
= Commands that give E24 (privilege violation) if not
administrator level.
27

Customization
In the IPL T SF interface family, varying degrees of
customization are possible. Server Side Includes make it
possible to obtain information from the unit and display
the information on Web pages. URL encoding allows you
to send information and commands to the unit to change its
configuration or provide you with feedback.
Server Side Includes
Server Side Includes (SSIs) are a type of HTML comment that
directs the Web server to dynamically generate data for a Web
page whenever it is requested. SSIs typically use Extron’s
Simple Instruction Set (SIS) to communicate commands to
the products or attached control devices. Using SSIs, custom
pages can be designed and displayed, with IPL T SF interface
information provided by the SIS commands.
The basic format for an Extron SSI is
<!—#echo var=”x”—>
Where x is the SIS command to be executed.
The SIS instructions sent to IP Link-enabled products fall into
two categories: “host” or “remote”.
•
Host commands instruct the IP Link product to act or
respond.
•
Remote commands pass data to an external control port
on an IP Link product.
When a Web page is requested, the Web server removes the
SSI and replaces it with the answer to the SIS command within
quotes.

Figure 4-22 — Example of SSI “remote” command
In figure 4-22 above, a “remote” serial command sends the
word “hello” and waits up to 50 ms for a response (until
three characters are received). For more information on this
command, refer to the “Programmer’s Guide for the Telnet and
Web Browser,” earlier in this chapter.
Query string
A query string is the portion of a URL that appears after the
question mark. The query string contains parameters or
instructions for the Web server to execute.
The basic format for a query string within a link is
<a href=”index.html?cmd=x”>Input #1</a> Where x is the SIS command to be executed.
When a link is accessed on a Web page, the URL is passed to the
Web server to tell it which Web page to return to the browser.
The portion of the URL after the question mark is the query
string, which contains the SIS command that the IP Link product
will remove and execute.
As with SSI formatted commands, query strings can use any
valid SIS command—either “host” or “remote”.
The query string in figure 4-23 below turns off DHCP on the IP
Link device.

Figure 4-24 — Example of a remote query string
command
In figure 4-24 above, the data string that follows the pipe (|)
symbol is sent to the attached controlled device on serial port #2.
This string will instruct an attached Extron switcher to change to
input #1.
Code examples
This section shows practical uses for both SSIs and query
strings.
N Before attempting to develop new Web pages, the user
should have a good, working knowledge of JavaScript,
HTML, and server side includes.
Example 1
In figure 4-25a, both host SSI and remote SSI commands are
used within the same Web page. You will notice six SSIs: three
host commands and three remote commands.

Example 5
This example demonstrates how to send out an IR string from
the IPL T SFI244. The line below shows an HTML hyperlink
with an Extron IR command encoded into the URL.
<a href=”index.html?cmd=W1*1*15*0ir|”>Play</a>
The ? cmd=W1*1*15*0ir| is the syntax for the URL encoding
of an IR command that will be sent out of IR port #1. The “W”
and the “|” (pipe symbol) are used as the leading and trailing
delimiters for the instruction that tells the box which port
number, .eir file or function within the .eir file to send. The
command also allows the programmer to define whether the
IR should be sent once or continuously until stopped. The IR
Learner program determines which IR function, such as play, is
assigned to which number. See the IR Learner program for help
with this feature.

URL encoding
URL encoding is the method of using ASCII hexadecimal
characters to display specific characters in a URL. URL
encoding is used for several reasons. On some operating
systems, certain characters are unsafe or not available, and
others are reserved by the HTML or URL specification. URL
encoding is used to ensure compatibility and functionality with
most Internet browsers. As a general rule, use the hexadecimal
encoding method shown below when these characters appear in
your URLs. The following types of characters do not require encoding in a
URL.
alphanumerics
0-9 a-z A-Z
special characters
$__.+!*(),
reserved characters
;/?:@=&
When used for their reserved purposes, these
characters do not require encoding within a URL.

IPL T SF Series • Communication and Control
A/V Device Control
Control of A/V devices may be accomplished in any of several
ways once the IPL T SF interface has been connected and
configured. These include Web pages, Telnet, and direct port
access.
Custom Web pages
These pages can either be modified versions of the existing Web
pages, or new Web pages developed in the field.
Web page development can be done with a Web site
development tool such as Frontpage or Dreamweaver. Custom
Web pages are loadable with the Web server File Manager (see
“Managing files” earlier in this chapter).
Telnet (Port 23)
Telnet, short for Telecommunications Network, provides a way
for you to connect to a computer or server (in this case the
IPL T SF interface) on a network. Once connected via Telnet,
you can send ASCII serial commands (see the “Programmer’s
Guide for the Telnet and Web Browser” earlier in this chapter)
to control devices connected to the interface through both serial
ports. Telnet only works in RS-232 mode.
Accessing and using Telnet
1.
Click Start, then Run and type “Telnet”. Click OK. The
Telnet program starts (see figure 4-31).
2.
At the command prompt, type “open” and press Enter.
3.
At the < to > prompt, type the IP address of the IPL T SF
unit. (The default IP address is 192.168.254.254, but it may
have been changed in the setup or configuration process.
If it was changed, use the new address.) Telnet defaults to
port 23.

4.
If passwords were set up for the connected system, you
will be prompted to log in as Administrator or User.
Otherwise, the system responds with a <cr/lf>.
Figure 4-32 — Connecting to the IP address
5.
Once you are connected, you can enter serial (ASCII)
commands as desired.
6.
When you are through entering commands to the interface,
type “quit” at the command prompt to quit Telnet.
Direct port access (ports 2001 through 2002)
Direct access allows a direct, one-to-one connection to any of the
serial ports using a reserved IP port number:
COM1: direct access port #2001
COM2: direct access port #2002
When a TCP session is initiated to port 2001 through port 2002,
all data sent and received passes directly to and from that port
without any processing. Serial port parameters should be set
via a Telnet connection prior to using direct access.
Using direct access
4-44
1.
Access the unit via Telnet and configure the COM port
parameters as desired using serial commands (see the
“Command/response table” earlier in this chapter).
2.
Close the initial Telnet session.
3.
Open a direct access Telnet session to the selected port by
entering the IP address followed by a space then the port
number (e.g., 192.168.244.244 2001).
4.
Send serial commands directly through the selected COM
port to the attached A/V device.
IPL T SF Series • Communication and Control
5.
Close the Telnet session to end the direct access session.
N You can force the direct access session closed by logging on
as Administrator and entering “Esc X! * 0CD}”, where
X! is the selected COM port.
Port redirect
Using the port redirector, either serial port can be configured as
a pass-through connection, allowing data to be sent and received
directly to and from the serial port back to the client (PC)
without any processing. In figure 4-33, a MediaLink® controller
connected to serial port 1 (COM1) is controlling a projector and
input devices connected to serial port 2 (COM2).

Port redirect can also be used in conjunction with Extron’s Serial
Link Software (refer to the Serial Link Software User’s Guide) to set
up virtual COM ports on a PC or laptop, to monitor COM port
data and pass it to the LAN, or to set up a projector or other
RS-232 controlled A/V devices via the IPL T SF interface. Port
redirect is enabled with an SIS command (see the “Command/
response table” earlier in this chapter).
Troubleshooting
Turn on output device(s) (plasma screens, monitors, projectors),
the IPL T SF control interface and the control devices (PC,
laptop, etc.).
IPL T SF Series • Communication and Control
4-45
Communication and Control, cont’d
If the output A/V device cannot be remotely controlled, check
the following:
Power connections
1.
Ensure that all devices are plugged in.
2.
Make sure that each device is receiving power. The
interface’s front panel power LEDs light if the device is
receiving power.
Data connections
1.
Check the cabling connections and make adjustments as
needed. The Link LEDs on the IPL T SF control interface
and the computer should be solid green if a network
connection is detected. If these LEDs are not lit, either
the cable is faulty or not plugged in, or the wrong type of
cable is being used (refer to “Connecting the Hardware”, in
chapter 3).
2.
Try to ‘ping’ the unit by typing “ping 192.168.254.254”
at the DOS command prompt, or use the Web address
provided to you by your system administrator. If you get
no response:
3.
a.
Make sure your unit is using the appropriate subnet
mask (check with your system administrator).
b.
Make sure your PC does not have a software firewall
program which might block the IP address of the
unit.
If contact is established with the unit, but the unit’s Web
pages cannot be accessed by your Web browser, verify (in
the Options or Preferences menu) that your Web browser is
configured for direct network connection and not set up to
use a proxy server.
If you are still experiencing problems, call the Extron S3 Sales
& Technical Support Hotline if needed. See the back of this
manual for the telephone number for your region.

10/100Base-T is Ethernet which uses Unshielded Twisted Pair
(UTP - CAT 5, etc.) cable, where the amount of data transmitted
between two points in a given amount of time is equal to either
10 Mbps or 100 Mbps.
Address Resolution Protocol (ARP) ARP is a protocol which
assigns an IP address to a device based on the device’s MAC or
physical machine address.
Custom Web page is any file that can be loaded into an IPL T SF
box and served by the IPL T SF’s internal Web server. A custom
Web page can provide control of devices attached to the IPL T SF
without use of the GlobalViewer® (GV) or Global Configurator
(GC). This is true with or without an accompanying event
script. Any number and size of graphics can be used, but if
they are too large to fit on the IPL T SF, you can write your Web
page so that they can be served from another Web server. If
you install Microsoft Internet Information Services (IIS) on your
desktop, you can serve any page on its hard disk. The IPL T SF
functions like a little computer with a Web server—you can use
it for various Web tasks.
DHCP is the Dynamic Host Configuration Protocol (DHCP),
which is a standardized communications protocol that enables
network administrators to locally and automatically manage
the assignment of IP addresses in an organization’s network.
Driver is a GC compatible package and includes the event script
that controls devices.
Ethernet is a network protocol that uses MAC addresses instead
of IP addresses to exchange data between computers. Using
ARP (see above), with TCP/IP support, Ethernet devices
can be connected to the Internet. An Ethernet LAN typically
uses unshielded twisted pair (UTP) wires. Ethernet systems
currently provide transmission speeds of 10 Mbps or 100 Mbps.
Event script is a program that runs on an IPL T SF box,
and issues queries and commands to the attached devices.
Event scripts are written in the “Extron C” language (.sc),
and compiled into an event script (.evt). GC performs this
compilation. The compiled result (.evt) is loaded onto the IPL T
SF box. The Extron C language is similar to ANSI C, with some
differences. As long as event scripts are turned on, event scripts
run continuously on the unit.
Floating is the condition of a device or circuit that is not
grounded and not tied to any established potential.

Global Configurator (GC) is a windows program that, based
on user input, creates a GlobalViewer (GV). GC requests
system information such as which devices you have and your
current list of IP addresses. With this information, GC creates
a GlobalViewer for your specific devices. GC also compiles the
event scripts and loads the GV and event scripts onto the box.
When using GC, the user must specify the port number for each
device (for attached devices to be controlled, they must be on
that port). In order for multiple IP-Link® boxes to appear in the
same GV, all the boxes must be configured at the same time,
using GC.
GlobalViewer (GV) is a set of Web pages (HTML, XML, JS)
and graphics that are loaded into the memory of an IPL T SF
unit. These pages provide an interface for control of devices
attached to the IPL T SF unit. They communicate with the
event scripts running on the box, and the event scripts issue
the commands and queries. This communication between the
Web pages and the event scripts occurs through predetermined
memory locations in the IPL T SF box. GV is initially created
by GC; however, it is possible to edit the GV HTML, XML, and
JavaScript files outside of Global Configurator. This edited GV
is called “hard-coded” or manually generated GV.
HTTP is an acronym for the HyperText Transfer Protocol
(HTTP), a Web protocol based on TCP/IP, that is used to fetch
HyperText objects from remote Web pages.
Hysteresis (deadband) is the lag that exists between the
responding parameter and the changing parameter.
Internet Protocol (IP) is the protocol or standard used to send
information from one computer to another on the Internet.
IP address is a unique, 32-bit binary number (12 digit decimal
number, xxx.xxx.xxx.xxx) that identifies each sender and each
receiver of information connected to a LAN, WAN, or the
Internet. IP addresses can be static (see Static IP) or dynamic
(see DHCP).
IP Netmask is a 32-bit binary number (12 digit decimal number,
xxx.xxx.xxx.xxx) used on subnets (smaller, local networks) to
help the router determine which network traffic gets routed
internally to local computers and which network traffic goes out
on the Internet.
Media Access Control (MAC) Address is a unique hardware
number given to devices that connect to the Internet. When
your computer or networking device (router, hub, interface, etc.)
is connected to the Internet, a table (see ARP) relates the device’s
IP address to its corresponding physical (MAC) address on the
LAN.

Pass-through allows control systems to work with the IPL T SF
unit and provides a link between two ports.
Ping is a utility that tests network connections. It is used to
determine if the host has an operating connection and is able to
exchange information with another host.
Port number is a preassigned address within a server that
provides a direct route from the application to the Transport
layer or from the Transport layer to the application of a TCP/IP
system.
Static IP refers to an IP address that has been specifically
(instead of dynamically—see DHCP) assigned to a device
or system in a network configuration. This type of address
requires manual configuration of the actual network device
or system and can only be changed manually or by enabling
DHCP.
Transmission Control Protocol/Internet Protocol (TCP/IP)
is the communication protocol (language) of the Internet.
Computers and devices with direct access to the Internet are
provided with a copy of the TCP/IP program to allow them to
send and receive information in an understandable form.
Telnet is a utility available on most PCs that allows the
computer system to communicate with one of its remote users/
clients. A user who wishes to access a remote system initiates a
Telnet session, using the address of the remote client. The user
may be prompted to provide a user name and password if the
client is set up to require them.
