Contemporary Research Corporation 3 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

oCreates on-screen channel labels, messages, text menus, and feedback using onboard

character generator

oReceives wireless commands from included IC-RC IR remote from internal IR sensors, external

sensor optional

oDelivers absolute volume control for level and mute

oManages channel access using programmable available channel list

oDelivers absolute power control with included power sensor

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

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.

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

Contemporary Research Corporation 6 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 7 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.

Contemporary Research Corporation 8 IR TV Controller

On-Screen Setup Menus

The remaining installation steps use the IR remote and the built-in character generator of the IRC.

1. Touch Menu, then 999, then Enter.

2. The text CR MENU> should appear on the screen.

3. Key in one of the commands shown below, then press Enter to activate.

4. Note that, in Menu mode, the Channel Down key acts as a backspace/delete key.

Contemporary Research Corporation 9 IR TV Controller

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>,<parameter> [<cmdN>]"

$A5 Starts the command

<dh> The zone or high order byte of the device

<dl> The unit or low order byte of the device (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>
