Overview

The ICC1-232 RS-232 Display Controller delivers economical 1-way control for power, volume, channels, and

available control lockout commands, receiving iCC-Net network commands over the same broadband coax that

carries the CATV channels. Compact in size and price, the ICC1-232 features discrete power control and

intelligent tuning from a channel list stored in onboard non-volatile memory. Tuning options include analog- and

HDTV-format channels.

High-speed 1-way control is possible through the same RF cable that carries the TV channels, creating

networked operation of distributed media systems without adding control wiring. Compatible with the

Contemporary Research SignStream™, iC-Web, and iC Commander software, the ICC1-232 can be networked

with up to 4000 display controllers. For custom systems applications, the ICC1-232 and other CR display

controllers can be accessed from a single RS-232 or Telnet port on an ICE-HE Ethernet Head End.

Applications include signage and video distribution for retail stores, theme parks, museums, government

facilities, sports venues, worship spaces, convention centers, airports and corporate video networks..

Contemporary Research 2 ICC1-232 Manual

Installation

AC Power Test

1. Insert DC power supply plug into 12 VDC jack.

2. Plug power adaptor into AC wall outlet.

3. The Net LED should turn on and stay lit.

RS-232 Control Wiring

1. Attach the CC-RS-232 or custom RS-232 cable to the ICC1-232 control port.

2. Connect the cable to the display’s RS-232 control input.

RF Coax and iCC-Net Operation

1. Connect the TV to CATV and observe quality of RF broadcasting. A low-quality CATV system can also

affect performance of the iCC-Net commands. If needed, fix CATV problems before installing the system.

2. Connect the CATV RF Coax cable into the RF In input on the ICC1-232.

3. If the iCC-Net signal is operating, the Net LED will blink once per second.

4. Connect the RF loop cable from the RF Out jack to the TV’s RF connector (remember, you lose less than

1.5 dbmV by going through the ICC1-232’S internal RF tap).

Installation

Setting RS-232 Control Codes

The DIP switches S1 and S1 at the bottom of the ICC1-232 serve in two modes, IR Type, Channel Entry and Device

Number, determined by S2 Switch 6 and S2 Switch 5. In this section, you’ll set up the manufacturer’s IR codes sent

from the IR Out port. These may have been set at the factory, or you’ll need to set them yourself.

1. Apply DC power to the ICC1-232.

2. If the unit’s device number has already been set, note the current settings for S1 switches 1-8 and S2 switches

1-4.

3. Set S2 Switch 6 to ON.

4. Look at the RS-232 Control Code chart on next page and select the desired value.

5. Set S1 Switches 1 – 6 to match the value. For example to select the Sharp HD codes (33),

turn on S1 switches 1 and 6, adding up to 5 to match the value in the RS-232 Chart on next page

6. If unit’s device number had been set before, return S1 switches 1-8 and S2 switches 1-4 to previous positions.

Installation

Setting Device Number and Parameters (Device Mode)

In the next step, you’ll need to set up the device number and operation parameters for the ICC1-232. Notice that

the functions of the S1 and S2 switches change when you set the unit in Device mode.

1. Make sure S2 Switch 6 is OFF (unit in Device mode).

2. Set the Device number by turning on the switches that add up to the desired device number. For

example, for Device #513 (1st device in Zone 2), S1 Switch 1 (1) and S2 Switch 2 (512) ON.

*Values in gray cells are the default settings.

Unit Address Switch Settings

The unique address of the controller is the combination of the values of the Zone (S2) and Unit (S1) switches. For

example, the first controller in Zone 1 would be set to Zone 1 (256) in S2 and 1 (1) on S2, or 257. To control all

the displays in Zone one, Display Express sends a command to device 256. To control just the first unit, create a

Preset addressed to 257.

Installation Process and Documentation

Most dealers will pre-configure the controller’s address before hanging displays. After setting the address, use a

label that states the unit’s address and location. Some use this method:

Room 305 - 515 - 12/2

The first identifies the location/name of the display. The second shows the specific address. The last set shows

the switches in S1/S2 that are set to ON.

It’s a good idea to define all this first in a spreadsheet, with the columns defining the name, address, S1 and S2

ON settings. Then, one person can set up all the controllers and label them.

Once the controller is configured and labeled, it’s easier for less-trained installers to Velcro the controller on the

back of the display, provide power, and hang the displays.

It’s much easier to pre-configure ahead of time than perform the task once the displays are installed.

RS-232 Control Wiring

1. Connect the CC-232 cable from the ICC1-232 to the display.

2. Mount the ICC1-232 to the TV using included Velcro tape.

3. Connect DC power to unit.

RS-232 Control Protocol

Overview

RS-232 control for up to 4000 TV Controllers is provided through an iC-series Head-End Network Controller. The

ICE-HE Ethernet Head End manages iC-Net communication over RF Coax to ICC1 (1-way) and ICC2 (2-Way) TV

Controllers.

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 SmartZones in this manual.

In ABC-Net, 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>

iC-Net devices are arranged with a zone mindset. For example, a command sent to Device 256, which

triggers all the units in Zone 1, would be expressed as $A5, 1, 0 (first zone, device zero). A command sent

to 257 would be $A5, 1, 1 (first zone, device 1 in the zone). See iC-Net SmartZones toward the end of this

manual.
