Contemporary Research 2 ICE-HE Ethernet Head End
Contemporary Research introduces a new solution for intelligent television control and distributed media management, the ICE-HE Ethernet Head-End. Through a single Ethernet port, the ICE-HE can network thousands of iC-Net TV controllers, communicating over the same CATV cable that carries the media channels.
The industry-standard iC-Net protocol operates seamlessly over Ethernet networks, RS-232 control ports, RF coax, Cat5 wiring, and fiber optic cables. Custom control systems, ABC-Net Media Retrieval systems, iC Commander 4 software, and iC ToolKit software can easily integrate all TVs, video projectors, and plasma displays across a facility or campus.
The ICE-HE can distribute 2-way iCC-Net data over existing CATV RF cable. Employing clear-channel RF frequencies to transmit and receive data, the iCC-Net network is compatible with any CATV system without conflict with existing channels. The bi-directional network operates over a standard low-split cable system, simplifying installation and support. Control data can also be transmitted over Category 5 and Category 3 wiring, using the ICE-HE iCW-Net ports. Three iCW-Net ports are included, each capable of connecting thousands of ICW-Net format controllers over wiring runs of up to 3,300 feet (1
Km). In addition, iCW-Net data can be sent to remote locations over fiber and videoconferencing codecs.
Applications include educational television systems, presentation rooms, auditoriums, pay-per-view, theme parks, museums and industrial video networks.
Connects to TCP/IP Ethernet network via 10/100baseT port using a static IP address
Networks with up to 4,000 TVs through wired iCW-Net and broadband CATV iCC-Net networks o iCC-Net operates through same CATV coax as TV channels, requires no additional wiring o iCW-Net distributes data over Category 5 or 3 wiring, fiber optic cable, or codecs
Sends commands to individual devices, zones, or all units from a single RS-232 port
Interacts with CR ABC Media Retrieval Systems, iC Commander software, or custom control systems
Includes local control buttons and I/O ports that can trigger events in PC software or control systems
Provides LED feedback for network, control, and operation status

Contemporary Research 6 ICE-HE Ethernet Head End
Remote Control Connection
1. Attach appropriate RS-232 cable to Remote Control RS-232 port. See page 4 for RS-232 cable wiring diagram.
2. Set desired baud rate on front-panel DIP switch. Default setting is 19.2K baud – see page 4 for
DIP switch setting information.
3. Alternatively, connect via Ethernet, setup instructions on the next page.
RF Coax and iCC-Net Operation
1. Connect an RF coax feed from RF Out to the system‘s RF combiner, mixing the iCC-Net Out signal with the other CATV channels. The iCC-Net Out channel operates at 74.7 MHz, in between cable channels 4 and 5.
2. In most applications, the installer will connect the included 10 dB attenuator in between, trimming the He‘s standard 55 dB output to 45 dB.
3. Using an RF signal level meter, use the front panel RF Out adjustment counterclockwise to match the RF Out signal to the other CATV sources. Limit RF Out adjustment to -10 dB, using attenuators to achieve a lower signal strength.
4. Add a Sub-CATV Diplexer after the CATV amplifier.
5. Connect the Sub-Channel output of the Diplexer to the HE RF In connection.
AC Power and Net LED operation
1. Insert DC power supply plug into the Power In jack.
2. Plug power adaptor into AC wall outlet, the front-panel LEDs should turn on momentarily.
3. If iC-Net communication is functioning, the Net LED will flash once per second, or twice per second (the double-flash, indicating a difference between present and expected device, would be typical in the initial phase of the installation.)
4. Using a terminal emulator, send an AR command (p9) a few times to measure the level of background RF compared to the current Sensitivity setting (DIP switch 1, p4).
5. Set one iC-Net controller to constantly transmit using iC ToolKit. Send the AR command again the measure the level at Constant Transmit.
6. The Sensitivity level should be set in-between the background RF and constant transmit levels.
I/O Port Connection
1. A simple contact closure can be wired to I/O 1 or 2, a press or release can trigger events in the
PC or control system software.
2. In other applications, the I/O ports can act as closure outputs, activating an external power relay,
2x1 video switcher or other device.
3. You‘ll have to choose application – the ports act as either an output or input, not both. See
Control Connections on page 5 for wiring and rating information.
Contemporary Research 7 ICE-HE Ethernet Head End
Ethernet Connection
The ICE-HE typically communicates over a network using a static IP address, and is shipped set to a default address:
IP Address: 192.168.1.251
Subnet Mask: 255.255.255.0
Gateway Address: 000.000.000.000
Odds are, at least the IP address will change when the ICE-HE is connected to the client‘s network.
One your first steps will be to obtain a static address from the client‘s IT department, as well as an external gateway IP address if you intend on supporting the system from your office or anywhere outside the site‘s firewall.
Once you change the settings, create a label noting the settings and attach to the back of the ICE-HE.
Reset IP Address
If you change the default address and forget what it is later on, you can always reset the ICE-HE back to the default settings using the unit‘s front-panel DIP switch 2. While the power is on, flip the switch off, then back on to reset the IP address. The IP and Subnet Mask will change, the Gateway will stay at its current setting.
Since its possible another network device is using the default IP address, the best approach is to enter the new settings offline, outside the network. You can use one of two, requiring one of two offline options:
1. Direct PC Connection. Use an Ethernet ―Crossover‖ cable to make a direct connection to the
ICE-HE Ethernet port and your PC. Two pairs of wires are reversed at one end to create a direct send/receive path for data.
2. Hub or Switch Connection. Another approach for connection is to use a standard Ethernet hub or switch between your computer and the ICE-HE. Using standard Cat5 Ethernet cables, connect your PC to one port, then connect the ICE-HE to the second port.
RS-232 and Telnet Terminal Communication
You can communicate with the ICE-HE with HyperTerminal using an RS-232 or TCP/IP connection to
Port 2728. This can be a more flexible tool than the Web Server, because you can view and change IP address information, as well as cross-check iC-Net devices and RF receive levels.
Contemporary Research 8 ICE-HE Ethernet Head End
Connecting to ICE-HE Web Server
Once you‘ve established an Ethernet connection to the ICE-HE, enter http://192.168.1.251 to connect to the unit‘s onboard Web server. You should see the ICE-HE home page in your browser. Your PC‘s IP address must be in the same group as the ICE-HE. For example, when the HE is set to 192.168.1.251, your IP address must be set to 192.168.1.x.
View or Change Ethernet Settings Via the ICE-HE Web Server

L Returns four hex bytes, separated by commas. If any of the bytes change as you repeat the command, there is likely an error in return communication from iC-Net devices.
DL Clears the L hex bytes to zero.
AR Level RF Received (idle) background level, no units constantly transmitting
Example Responses:
AR RRRR/SSSS = Receive/Sensitivity levels
AR 0321/1337 = 0.321V “quiet” receive level, 1.337V high threshold
AR 0321/0693 = 0.321V “quiet” receive level, 0.693V low threshold
AR 2250/0693 = 2.251V constant transmit receive level, 0.693V low threshold
This command is used to check RF levels at 5.6MHz, compared to the current sensitivity level setting (DIP Switch 1, page 4). Test the RF receive level a few times when the iC-Net units are not transmitting, then again when one iC-Net unit is set to constantly transmit. The Sensitivity level should fall about halfway between quiet and constant transmit RF levels.
AO Displays RF output level
Example Response: AO 5000* (Full Output)
AS Displays DIP switch setting in binary format
Example Response: AS 222* (Switches 1 and 6 off)

Contemporary Research 11 ICE-HE Ethernet Head End
Overview
RS-232 control for up to 4000 iC-Net devices is provided through an iC series Head-End Network
Controller. The ICC-HE Head-End manages iC-Net communication over RF Coax to ICC-series devices as well as ICW-series devices over twisted-pair Cat3/5 wiring. The ICW-HE Head-End operates on the
Cat5 network only.
Each device is assigned a unique device number from 1 to 4000 to which control commands are addressed. The devices are organized into 16 zones of 255 devices. All the devices in each zone will respond to a single ―virtual device number‖ — one device number that represents all devices in each zone. There is also a global device number, 4095, that will command all devices in the system. This feature dramatically speeds up system operation and programming, because one command can affect an entire group of devices—or all. To take advantages of this feature, review the section iC-Net Zones in this manual.
In ABC-Net Media Retrieval Systems, we reserve the first group of devices, 1-255, for components operating on a connected control system. Zones 1-16 are used for CR TV Controllers, Video Display
Controllers and Tuners. As it‘s unlikely any system will use all 4000 devices, this may be a good device standard for your system as well.
The Remote RS-232 port on the Head-End Network Controller can communicate from 1200 to 38.4K baud. The factory default setting is 19.2K baud, 8 data bits, No parity, and 1 stop bit.
Command String Structure
Characters in command strings are expressed in a combination of hex and ASCII characters.
Single-byte hex numbers are preceded by the „$‟ symbol
ASCII characters or strings are enclosed in single quotes
Numbers not marked as hex or ASCII are a single decimal byte
Parameters shown in < > brackets are single byte

On-Screen Text Commands
Command Description
Write Text
Advanced
Fast Write
DM “$A5,<dh>,<dl>,<ncb>,„DM‟, <start line>,<text color>,<background color>, <background>,<size and shadow>,<timeout>,<message bytes>”
(variable bytes)
Clears current text, displays text message over video (default) or blank background. The built-in character generator can accept up to 40 characters of text (including carriage returns), 28 characters per line. Use a hex $0D or decimal 13 in the text as a carriage return, which will advance CG to the next line, first space on the right.
Start Line - 1-11
Text Color - 1-7= White
Text Background Color – 0-7=Transparent (no background)
Full screen background – 0=normal insert over video, 1=blue screen
Size and Shadow – 0-3=small text with drop shadow
Time-Out – 0=15-second display, 1=persistent
Persistent text stays on screen until the next DM, or new Menu or channel.
Ex1: “$A5,<dh>,<dl>,10,„DM‟, 2,7,0,0,1,0,‟TEST‟ ” displays the word
TEST on the second line, white text, inserted over video, small size with drop shadow, and timing out after 15 seconds.
Ex2: “$A5,<dh>,<dl>,2,„DM‟ ” clears on-screen display, also clears persistent text
The IRC and VDC use white text and clear backgrounds when it receives a
Text or Background Color parameter between 1 and 7, and accepts values
0-3 for text size and shadow. This allows compatibility with Smart TVs mixed in the same system that can display other colors and fonts.
The following commands provide advanced CG text operation
DN “$A5,<dh>,<dl>,<ncb>,‟DN‟, <text> ” (variable bytes)
Clears display, writes specified text starting at column 1, row 1. $0D and hex $EA, $EB, $DC, and $DB can be included, operate same as matching commands below.
Write Here DW “$A5,<dh>,<dl>,<ncb>,‟DW‟, <text> ” (variable bytes)
Writes specified text starting at present cursor position. Accepts same Hex
Row,
Column as DN.
DG “$A5,<dh>,<dl>,4,‟DG‟, <row>, <column>” (8 bytes)
Moves the cursor to the specified row and column position. If row is 0, then row will not be changed, and if column is 0, then column will not be changed.
Cursor
Column
E7 “$A5,<dh>,<dl>,3,‟E7‟, <column>” (7 bytes)
Sends cursor to specified column.
Cursor Row E8 “$A5,<dh>,<dl>,3,‟E8‟, <row>” (7 bytes)

Contemporary Research 2-way iC-Net devices will send a response over the network whenever there is there is a change in status or command from an IR remote or front panel.
Response String Structure
Characters in response strings are expressed in a combination of hex and ASCII characters. For clarity, the following protocol examples use the following conventions:
ASCII characters or strings are shown enclosed in single quotes
Numbers shown that are not in single quotes are a single decimal byte
Parameters shown in < > brackets are single byte
A series of multiple commands or parameters are set apart by [ ] brackets
Commas separate the bytes, but are not part of the protocol
Double quotes enclose the command string, but are not part of the protocol
Command format
― ‗<‘,<dh>,<dl>,<nrb>,<rb1>, <para1> [<rbN>]"
‗<‘
<dh>
<dl>
<nrb>
<rb1>
Starts the response
The zone or high order byte of the device
The unit or low order byte of the device (0 for global zone)
The number of response bytes to follow
The first response byte
<para1>
[<rbN>]
Associated parameters, if any
Multiple responses may be included
Contemporary Research 19 ICE-HE Ethernet Head End
The following responses apply to the HE only.
Response Description
Key-I/O
Device Query
K “ „<‟,0,0,2,'K',<IR Key>" (6 bytes)
Sent when the Reset or Emergency buttons are pressed, or when I/O 1 or 2 receives a closure.
PC software or a control system connected to the Control RS-232 port can receive the response and activate a programmed event.
101 = Reset button pressed 229 = Reset button released
102 = Emergency button pressed
103 = I/O 1 input closed
230 = Emergency button released
231 = I/O 1 input opened
104 = I/O 2 input closed 232 = I/O 2 input opened
SP " '<',0,0,4,'SP',<number devices present>,<number devices expected> (8 bytes)
Sent in response to HE Device Status query.
Tip: If the number of present and expected devices match, the green Net LED on the HE will blink once per second. If the two numbers do not agree, the LED blinks twice per second.

23 = Channel Down
29 = Menu
101 = Previous Channel
107 = Cursor Left
108 = Cursor Up
109 = Cursor Down
110 = Media Select
The 0 – 9, Channel Up/Down functions are sent only if enabled in the TM command
(Bit 2 = 1). The Channel Up/Down responses will be sent if the Tune Ring contains no channels – see Ex2 in the Tune Ring command section.
M “ „<‟,<dh>,<dl>,5,'M',<msh>, <msl>, <mph>, <mpl>" (9 bytes)
Sent when unit receives a new Menu command is pressed or released (0) from the IR remote. Menu
Selection high and low bytes are in <msh> and <msl>. Menu Parameter high and low bytes are in
<mph> and <mpl>.
A Menu command is initiated by pressing the Menu key, followed by a numeric entry, then the Enter or Channel Up key. During the Menu process, the Channel Down key acts as a backspace or delete key.
Some selections that need only a single numeric entry and will have a parameter value of zero (0).
Those keys are 0, 8, 9, 18, 20, 30, 900, 911, and 912.
Menu selections that will prompt the user to enter a second parameter entry are:
1 = Select Media
2 = Password
3 = Chapter Search
4 = Frame Search
11 = Channel
21 = Page Zone
22 = Page Room
25 = Go
21 = Attach Zone
32 = Attach Room
Tip: The Menu entries are active even if the TV power is off.
Contemporary Research 21 ICE-HE Ethernet Head End
To simplify controlling groups of devices, iC-Net is divided into 16 zones of 255 devices, also called
SmartZones. All the devices within each zone can be controlled simultaneously by sending a command to a single ―virtual device number‖.
For example, noting the SmartZone chart below, if we send a Power On command to device #256, any
TV controller numbered between 257 and 511 will instantly turn on. If we send a Power Off command to device #4095, all devices in the system will turn off.
This is an immensely powerful feature, because most systems can only address one device at time. So if you need to turn off all 50 TV in a zone, you would need to send 50 commands. In addition to the hassles of creating multiple commands, there would be a long delay between the first and last command. One command, instant response is easier.
ABC Media Retrieval Systems reserve Zone 0 for devices used in the central control system, 1 -15 for iC-Net devices. This structure may be useful for your application, or you could use Zone 0 just like any other iC-Net zone.

Tip:You've probably figured out that you never want to assign a virtual device number to an actual device in the system. If you assigned #1536 to a device, all the TV controllers in Zone 6 would respond every time you sent a command to that one device.

Frequencies -—The visual carrier frequency (channels T7-116) is shown in this chart, in MHz. For the aural carrier frequency, add 4.5 MHz to the visual carrier. The lower edge of the channel is 1.25 MHz below the visual carrier and the upper edge is 4.75 MHz above the visual carrier.
CATV/IRC — IRC spacing is the same as standard CATV frequencies, except for Channels 5 and 6.
HRC/IRC — About 10% of CATV systems use these alternate frequency plans, created to reduce ―beat‖ interference.
FCC – U.S. Broadcast VHF/UHF
*Channel 1 — IRC/HRC spacing created a Channel 1 between 4 and 5, the rarely used channel must be shifted to different frequency for IC-Net operation
