Contemporary Research 3 ICC2-IRC
Overview
The ICC2-IRC delivers intelligent, interactive distributed media management. Communicating bi-directionally
over the same RF coax that carries the CATV channels, the ICC2-IRC dramatically simplifies system installation.
The ICC2-IRC features an internal TV tuner for absolute channel access management and a character generator
that outputs on-screen text for channel names, control functions, and interactive menus. Intelligent tuning,
volume and power control is provided by IR control port and included scan sensor. Front-panel control and LEDs
keep users in touch with their system. A full range of control choices is available with the optional
IC-RC IR Wireless Remote, designed for simplified control of distributed media channels and sources.
Compatible with the Contemporary Research ABC-Net Media Retrieval System and other CR software solutions,
the ICC2-IRC TV Controllers can be networked seamlessly with other TV and Video Display controllers. For
custom systems applications, all IRC units and other iC-Net devices can be accessed from a single RS-232 port
on ICC-HE and ICE-HE Head-End Network Controllers.

input does not see scanning activity, the Power LED blinks rapidly.
Net LED Blinks when it is receiving network data
LED Response
Off –DC power to IRC missing or other internal power problem
Solid On –no network communication
Blinks once per second - communicating over network
The Head-End Network Controller sends out a ―heartbeat‖ command once every
second that will flash the Net LED.

Contemporary Research 6 ICC2-IRC
Installation
AC Power
1. Insert DC power supply plug into 12 VDC jack on the IRC.
2. Plug power adaptor into AC wall outlet.
3. The Net LED should turn on and stay lit.
RF Coax and iCC-Net Operation
1. Connect the RF Coax cable into the Antenna/Cable input on the IRC.
2. If the iCC-Net signal is operating, the Net LED will blink once per second (ICC2-IRC only).
TV Power Sensing
1. Press the Power button on the IRC.
2. The Power LED should blink, indicating that the IRC knows the TV should be on, but is not sensing the
presence of TV scanning operation.
3. Insert the CC-HSD Scan Sensor plug into the IRC Power Sensor jack.
4. Turn on the TV using the TV‘s power button.
5. Move the CC-HSD sensor block around the rear of the TV to pick up scanning signal from the TV‘s
horizontal transformer
6. Watch the IRC Power LED as you move the sensor, stop moving when the LED stops blinking.
7. Turn the TV on and off from its own power button, testing if the IRC is reliably sensing power.
8. Mount the sensor to the TV, using the enclosed Velcro tape.
Tip: The best location for the sensor is usually on the lower left rear corner side corner (looking
from the front), and it may help to rotate the sensor to search for best performance.

Contemporary Research 7 ICC2-IRC
A/V Setup
1. Connect audio and video outputs of the IRC into the audio and video inputs of the TV.
2. You may use the left or right IRC audio output for a TV with mono audio, both for a TV with stereo audio
(IRC sound is mono).
3. Select the External Video/Aux inputs on the TV to view on-screen setup commands and A/V from the IRC
(Most TVs don‘t have a discrete Video input command).
IR Control Wiring
1. Connect the CC-IRE IR Emitter plug into the IRC IR Out jack.
2. Mount the emitter cube to the TV case where the TV receives IR commands.
3. Place the IRC near the TV within line-of-sight control from the IC-RC wireless IR remote. At this point, you
could fix the IRC into the final mounting position above or below the TV, or simply place the IRC so you
can complete the IR setup procedure.
Tip: At this point, you’ve set up the control wiring, the manufacturer’s codes sent will be
programmed or changed with the On-Screen Setup Menu 45700. Press the Power button on the
IRC. If the TV turns on and off, the settings are already correct.
IR Mode and Power Sensing
Newer IRC models set the IR and Sensing options via the On-Screen Setup Menu 45702. Some ICW-IRC units
include a DIP switch (S6), located inside the IRC, to set IR options and TV Power sensing. Note this affects the
front-panel sensing, not an external IR sensor. Turning off both sensors would limit sensing to the external IR
sensor only. If you have two adjacent TVs (or one on each side of a wall), you may want to lower TV power
sensing. Some TVs prefer a lower IR output, most work fine with the standard level.

Programming the IC-RC Remote
In order to complete the setup of the IRC, you‘ll need the IC-RC IR Remote to use the On-Screen Menus.
Typically, the remote is shipped ready to communicate to the IRC (Code 9). Just in case, here‘s how to set the
format of IR codes in the remote:
1. Press and hold the Select button and a numeric key for the code # below.
2. Release the two keys at the same time.
3. The remote will now send the selected codes.
4. Remote will keep the codes, even if battery power is lost.

RS-232 Control Protocol
Overview
RS-232 control for up to 4000 ICC2-IRC and ICW-IRC TV Controllers is provided through an iC-series Head-End
Network Controller. The ICC-HE Head-End manages iC-Net communication over RF Coax to ICC2-IRC TV
Controllers as well as ICW-IRC TV Controllers over twisted-pair Cat3/5 wiring. The ICW-HE Head-End operates
on the twisted-pair network only.
Each TV Controller 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 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. For clarity, the
following protocol examples use the following conventions:
Single-byte hex numbers are preceded by the ‗$‘ symbol
ASCII characters or strings are enclosed in single quotes
Numbers not marked as hex or ASCII are a single decimal byte
Parameters shown in < > brackets are single byte
A series of multiple commands or parameters are set apart by [ ] brackets
Commas separate the bytes, but are not part of the protocol
Double quotes enclose the command string, but are not part of the protocol
Command format:
―$A5,<dh>,<dl>,<ncb>,<cmd1>,<para> [<cmdN>]"
$A5 Starts the command
<dh> The zone or high order byte of the device (n times 256)*
<dl> The unit or low order byte of the device (number past dh - 0 for global zone)*
<ncb> The number of command bytes to follow
<cmd1> The first command byte
<parameter> Command parameters (not used by all commands)
[<cmdN>] Multiple commands can be concatenated, with byte count added to <ncb>
*Device number example: $A5,2,4=Device 516 (256*2 + 4)

Ex1: ―$A5,<dh>,<dl>,6,‗TN‘, 7, ‗PBS‘ ‖ IRC displays PBS when 7 is selected
Ex2: ―$A5,<dh>,<dl>,3,‗TN‘, 7 ‖ Clears alpha label for channel 7
Ex3: ―$A5,<dh>,<dl>,4,‗TN‘,0,0‖ Clears all alpha labels
Display Label
TC
―$A5,<dh>,<dl>,2,‘TC‘ ‖ (6 bytes) – Display current channel label for about 15 seconds
Closures
Y-
―$A5,<dh>,<dl>,3, ‗Y‘ <I/0 Port>‘ ‖ (7 bytes)
Turns the two internal closures on and off. Closure 1 is typically used to control the
optional buzzer, Closure 2 typically used to control an external camera power relay.
―$A5,<dh>,<dl>,3, ‗Y10‘‖ turns Closure 1 off
―$A5,<dh>,<dl>,3, ‗Y11‘‖ turns Closure 1 on
―$A5,<dh>,<dl>,3, ‗Y20‘‖ turns Closure 2 off
―$A5,<dh>,<dl>,3, ‗Y21‘‖ turns Closure 2 on

Description
Text
Write Text
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 $0D or decimal 13 in the text as a
carriage return, which will advance CG to the next line, first space on the right.
Start Line - 1-11
Text Color - 1-7= White
Text Background Color –0-7=Transparent (no background)
Full screen background –0=normal insert over video, 1=blank screen (blue)
Size and Shadow –0-3=small text with drop shadow
Time-Out –0=15-second display, 1=persistent
Persistent text stays on screen until the next DM, or new Menu or channel.
Ex1: ―$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 VDC uses 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.

RS-232 Responses
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>]"
‘>’ Starts the response
<dh> The zone or high order byte of the device
<dl> The unit or low order byte of the device (0 for global zone)
<nrb> The number of response bytes to follow
<rb1> The first response byte
<para1> Associated parameters, if any
[<rbN>] Multiple responses may be included
Response
Description
New Channel
T
― ‗<‘,<dh>,<dl>,2,'T',<new channel>" (6 bytes)
Sent in response to T? command.
IR Function
F
― ‗<‘,<dh>,<dl>,2,'F',<IR Function>" (6 bytes)
Sent when unit receives a new function command is pressed (1-8) or released (0) from
the IR remote.
0 = Release
1 = Play
2 = Stop
3 = Pause
4 = Fast Forward
5 = Rewind
8 = Record

Contemporary Research 16 ICC2-IRC
Response
Description
IR Key
K
― ‗<‘,<dh>,<dl>,2,'K',<IR Key>" (6 bytes)
Sent when unit receives a new key command is pressed (10-116) or released (0) from
the IR remote.
0 = Release 105 = Media Menu
10 - 19 = Numeric keypad entry 0 –9 106 = Cursor Right
21 = Enter 107 = Cursor Left
22 = Channel Up 108 = Cursor Up
23 = Channel Down 109 = Cursor Down
29 = Menu 110 = Media Select
101 = Previous Channel 116 = Timer
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.
IR Menu
M
― ‗<‘,<dh>,<dl>,5,'M',<msh>, <msl>, <mph>, <mpl>" (9 bytes)
Sent when IRC 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.
Device
Response
SP
" '<',0,0,4,'SP',<number devices present>,<number devices expected> (8 bytes)
Sent in response to HE 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.

iC-Net SmartZones
To simplify controlling groups of devices, iC-Net is divided into 16 zones of 255 devices, 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 zone 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 other 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. Sending one command, with instant response is far easier.
As we noted before, 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.

System Map
One of the key tasks for iC-Net integrators is to create a logical System Map, assigning device
numbers to TV controllers so they fall into logical zones. The device mapping could be sorted by type
or location; whichever suits the application.

Typical RF and ICC-Net Signal Flow
The diagram below shows the structure of a typical Contemporary Research media retrieval system.
One of the key aspects for iCC-Net communication is to provide a forward and return (sub-channel)
path for data.

Contemporary Research 20 ICC2-IRC
Mounting the IRC
In most cases, you‘ll mount the IRC directly to the TV, either below or above. Mounting below the TV
is preferred, as it‘s usually the best location for IR reception from remotes, and helps to screen the
internal IR sensors from stray ceiling-fixture IR.
Installers commonly use Velcro to secure the IRC to the TV. Others will use brackets, such as our
optional RK2 Brackets to mount the IRC to the TV, as shown below. Some combine the two
approaches, using Velcro during the initial phase of installation, then securing with brackets when
testing and troubleshooting is completed.
In all cases, it‘s best to mount the IRC near to the TV, monitor or video projector, simplifying wiring
for A/V and control cables. If, for some reason, the IRC must be mounted in an equipment rack,
you‘ll need an optional RK1 Rack Mount Kit. In addition, order the IRC with the external IR In input (a
factory-installed option) and an optional IR-RX External IR Receiver.
