Contemporary Research Corporation 2 IR TV Controller
Overview
Contemporary Research offers two solutions for intelligent, interactive distributed media management, the
ICC2-IRC and ICW-IRC IR TV Controllers. The ICC2-IRC communicates bi-directionally over the same RF coax
that carries the broadband TV channels, dramatically simplifying system wiring. The ICW-IRC connects over a
twisted-pair network using Category 5 or Category 3 wiring and connectors.
Both IRC TV Controllers feature 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. Enjoy a full range of control choices with the included
IC-RC IR Wireless Remote, designed for simplified control of distributed media channels and sources.
Compatible with the Contemporary Research ABC Media Retrieval System and iC Commander software, the IRC
TV Controllers can be networked with up to 4000 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
ICW-HE Head-End Network Controllers.
• Controls most brands of TVs from IR control port
o Creates on-screen channel labels, messages, text menus, and feedback using onboard
character generator
o Receives wireless commands from included IC-RC IR remote from internal IR sensors, external
sensor optional
o Delivers absolute volume control for level and mute
o Manages channel access using programmable available channel list
o Delivers absolute power control with included power sensor
• Networks with up to 4,000 TVs through an ICC-HE or ICW-HE Head-End Network Controller
o ICC2-IRC units provide 2-way operation over the same RF cable as CATV channels
o ICW-IRC connect over Category 3 or 5 wiring
o Units instantly respond to individual, zone, and all-call commands
• Provides front-panel control for power, volume, and channel, and LED feedback for power, IR control,
and network
• Includes A/V inputs to display video from PCs, overheads, cameras and other local video sources
• Restores all operation status after loss of power from data stored in non-volatile memory
• Enables and disables front-panel control via iC-Net protocol
• Mounts above, below, or near TV, mounting brackets included over the same RF coax as the distributed
media channels, simplifying system wiring and retrofit

Status Indication
The Net and Power LEDs have special modes that help system setup and troubleshooting.
Power LED Uses a blink mode when the IRC logic and Sensor feedback do not agree
For example, if the TV Controller knows the TV should be on, but the sensor
Net LED Blinks when it is receiving network data
The Head-End Network Controller sends out a “heartbeat” command once every
80 KHz max carrier deviation
Logic Sensor LED Response
ON ON Solid On
ON OFF Blinks – states do not agree
OFF OFF Solid Off
OFF ON Blinks – states do not agree
input does not see scanning activity, the Power LED blinks rapidly.
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
second that will flash the Net LED.
Contemporary Research Corporation 5 IR TV Controller
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).
iCW-Net Connection (ICW-IRC)
1. Plug the iCW-Net RJ-45 connector into the iCW-Net input on the ICW-IRC.
2. If the iCW-Net signal is operating, the Net LED will blink once per second.
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 Corporation 6 IR TV Controller
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.
Switch # Function Options
1 38 KHz IR Receive ON= 38 KHz IR
OFF= 38 KHz IR off (default)
2 57 KHz IR Receive ON= 57 KHz IR (default)
OFF= 57 KHz IR off
3 TV Power Sensing ON= High sensitivity (default)
OFF= Low sensitivity
4 IR Control Output ON= High IR output (default)
OFF= Low IR output
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.
IR Code Format Code
Zenith Smart TV 1
Philips Smart TV 2
RCA Smart TV 3
Contemporary Research 38 KHz 4
Contemporary Research 57 KHz (default) 9
Tip: Normally, the 57 KHz frequency works the best, avoiding most sources of IR interference.
The IRC has 38 KHz and 57 KHz sensors, so it can receive either frequency.
