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 3 ICC1-232 Manual

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.

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.

RS-232 Commands
Command Description
Channel Up TU NA
Channel Dwn TD NA
T Channel Prev TP NA
Force Channel TC “$A5,<dh>,<dl>,3,’TC’, <channel>” (7 bytes) – Tunes to a specific channel 2-127
Select Channel TT “$A5,<dh>,<dl>,2,’TT’,<channel>” (7 bytes) – Same as TC
Tune HD TH
Ex:
“$A5,<dh>,<dl>,5,’TH’,<H1>,<Major>,<Minor>” (9 bytes) – Digital Tuning
Normally, the H1 parameter is 0, allowing the ICC1-232 to use the current H1
tuning format, but it could be used to force a different tuning option. When the
display is set to the H1=1 mode, the Major-Minor bytes will represent the high and
low bytes of the 5-digit number. In H1=2 or 3 modes, the bytes represent the
Major and Minor channel numbers. Values may be in hex or decimal.
“$A5,1,4,5,’TH’,1,2,3” Device 260, channel 515
“$A5,1,4,5,’TH’,2,2,3” Device 260, virtual channel 2-3
“$A5,1,4,5,’TH’,3,2,3” Device 260, physical channel 2, minor 3

Tune Ring TR “$A5,<dh>,<dl>,<ncb>,’TR’, [<chan 1>, <chan N>]” (variable bytes)
This command stores a Tune Ring, Analog channels only , a series of preset
channels accessed by channel up/down commands.
Ex1: “$A5,<dh>,<dl>,6,’TR’, 5,4,8,11” sets ring to channels 5, 4, 8 and 11
Tip: The ring follows the stored order, channels do not have to be in ascending
order
Ex2: “$A5,<dh>,<dl>,8,’TR’, $82,5,$87,11” sets channels 2-5 and 7-11. You can
specify a range using MSB bit for the first channel; the next byte is the last.
Control Lock LM “$A5,<dh>,<dl>,3,'LM',<control>” (7 bytes)
0 = Off (unlocked)
1 = On (locked)
Locks out display commands from an IR remote or front-panel buttons. Feature is
not available for all models of displays. Check with CR Tech Support if this function
is important to your application.

Contemporary Research 10 ICC1-232 Manual
iC-Net Zones
To simplify controlling groups of devices, iC-Net is divided into 15 Zones of 255 devices. 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.
The ICC1-IR and ICC1-232 controllers typical for many SignStream display control systems are designed to
follow a Zone address format. You can use the 4 top switches in the second DIP switch (S2) to define the
controller’s Zone. You could stop at that point, or use the upper switches (S1) to define the controller’s address
within the Zone. For example, setting S2/1 On and S1/2 On defines that the controller is part of Zone 1 (256),
and is the second unit in the Zone (2). The unique address of the controller would be 258 (256 + 2)
Zone Device # Unit Total Device #
1 256 1-255 257-511
2 512 1-255 512-767
3 768 1-255 769-1023
4 1024 1-255 1025-1279

10 2560 1-255 2561-2815
11 2816 1-255 2817-3071
12 3072 1-255 3073-3327
13 3328 1-255 3329-3583
14 3584 1-255 3585-3839
15 3840 1-255 3841-4000
All Zones 4095
Tip:While many applications can use just the Zone number, it’s a good practice to assign a unique Unit
number to each controller in the zone. This allows the system software to address individual controllers if
necessary.

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.
