Contemporary Research 5 ICC1-IR
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.
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-IR.
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-IR’S internal RF tap).
TV Power Sensing
1. Insert the CC-HSD Scan Sensor plug into the Power Sensor jack.
2. Turn on the TV using the TV’s power button.
3. Move the CC-HSD sensor block around the rear of the TV to pick up scanning signal from the TV’s
horizontal transformer.
4. Watch the Power Sensor LED as you move the sensor, stop moving when the LED lights steady.
5. Turn the TV on and off from its own power button, testing if the unit is reliably sensing power.
6. 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.
Tip: IR control test: When you install the IR cable, flip S2 Switch 6 ON. Then flip S2 Switch 1 ON to send an
IR power command. Turn Switch 1 OFF, then turn Switch 2 on to send and Off IR command. After
testing, turn S2 Switch 6 OFF.

Installation
Setting IR Control Codes (IR Type Mode)
Turn enclosure so the DIP switches are on the bottom
In most cases, it’s easier to use our Display Express software, IC Send app, or your control system to change the IR
code set you want to use. See the section on page 11 on using our software to set the IR code set.
The DIP switches S1 and S1 at the bottom of the ICC1-IR 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-IR.
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. (if this is already sounding tedious, go to page 11)
3. Set S2 Switch 6 to ON.
4. Look at the IR 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 Sony codes,
turn on S1 switches 1 and 3, adding up to 5 to match the value in the Manufacturer IR chart below.
6. Set S1 Switch 7 to On if you want the unit to ignore the power sensor input
7. Set S1 Switch 8 to OFF for toggling Power On/Off command typical for most TVs. (There are a few international
TVs that use Key 1 for Power On)
8. Set S1 Switch 8 and S2 Switch 6 to OFF. (See Channel Entry option below)
9. If unit’s device number had been set before, return S1 switches 1-8 and S2 switches 1-4 to previous positions.

PC Sensor Setup: LCD marked PC Sensor (Power Current Sensor) do not have discrete IR power commands.
Instead, the ICC1-IR will wait for an “OFF” signal from a power sensor before it sends an ON IR command. Go
to our Support blog page Power Current Sensing for info on sensed absolute power control.
If you want to set the control for unsensed toggling power, turn DIP S1, Switch 7 ON when you set the IR code
with the DIP switches. If you are using IC-Send or Display Express Special Command feature, send the
command T1, with the IR code value + 64. For example, to set Olevia controllers to toggling power, send the
command T1, 102 (38+64).

Contemporary Research 9 ICC1-IR
Installation
Setting Device Number and Parameters (Device Mode)
Turn enclosure so the DIP switches are on the bottom
In the next step, you’ll need to set up the device number and operation parameters for the ICC1-IR. 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 #259, turn on S1 switches 1 and 2 (3), S2 switch 1 (256)
Zone Switch Settings (S2 –right side)

Unit Address 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.
IR Control Wiring
1. Connect the CC-IRE IR Emitter plug into the IR Out jack.
2. Mount the emitter cube to the TV case where the TV receives IR commands.
3. Mount the ICC1-IR to the TV using included Velcro tape.
4. Connect DC power to unit.

Contemporary Research 11 ICC1-IR
Writing Your Own Control Code
While most IC systems use our Display Express software to control displays, a growing number of integrator are
writing their own control applications, using AMX, Crestron, RTI, or other platforms. We encourage creative
solutions, and are happy to support those who take advantage of our protocol.
From our history of support activity, we are providing a few tips to help you on your way.
Device Numbers
iC-Net devices are arranged with a zone structure, arranged in 15 groups of 256 devices. The first address in the
group represents the entire zone. For example, Zone 2’s group address is 512 (2*256). When a command is
sent to 256, all controllers in that group will respond as one.
The Device values reflect that structure. The first number <dh> is the zone, from 1-15. The second defines the
unique address of the device, 1-255). 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 $A5, 1, 1
(first zone, device 1 in the zone). See iC-Net Zones toward the end of this manual.
String Format
Every software application has a different denotation for handling hex, ASCII, and decimal formats. The
examples in this manual are in AMX format, which is understood by many in the control industry:
Hex values begin with a dollar ($) symbol
ASCII values are enclosed in single quotes
Decimal values are shown as normal
If you plan on using a mixed-format structure for commands, convert the symbols to the types required by your
software application. For example, a Tune Channel 2-3 command to device 260 could be shown several ways:
AMX Mixed Format = “$A5,1,4,5,’TH’,2,2,3”
AMX Hex Format “$A5 $01 $04 $05 $54 $48 $02 $02 $03”
Standard Hex (no denotation) = A5 01 04 05 54 48 02 02 03
Crestron Hex Format = \xA5\x01\x04\x05\x54\x48\x02\x02\x03
RTI = Select port, Hex mode, enter A5 01 04 05 54 48 02 02 03
Go to www.asciitable.com for a handy Decimal/ASCII/Hex conversion chart.

Contemporary Research 12 ICC1-IR
Using Display Express or IC Send Software
IC Send
Once you’ve installed the ICC1 controllers, you can test the operation of the system using our IC Send software.
For more detailed information, go to Products/Software Tools/IC Send and download the ZIP file for the app and
manual. This easy-to-use tool can send commands to an IC-HE Head End RS-232 or Ethernet port. As you test
your code, the program will come in handy to prove the system is operating properly, or reset things you’ve
changed.
For example, to change the IR code set for a controller, enter T1 in the first field, the code # listed on page 7,
then the device # of the controller. For example, to set the controller to Sharp, use T1 and 46.

Contemporary Research 14 ICC1-IR
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
ICC-HE Head-End manages iC-Net communication over RF Coax to ICC1 (1-way) and ICC2 (2-Way) TV
Controllers as well as ICW 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 Display Express System, 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 [hex]
<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>

Sets TV volume level
0 = Mute
1 –63 = Minimum level (1) to maximum volume (63)
IR Type
T1
“$A5,<dh>,<dl>,3,’T1’,<type> ” (7 bytes) – Sets IR device type
Identical to using DIP switch to set IR control codes. Specify value to match IR code
type.
Add 64 to the IR code to set the ICC1-IR to ignore the power sensor –if the type is
specified as Sensor –discrete types always ignore the sensor input.
Channel Entry
T3
“$A5,<dh>,<dl>,3,’T3’, <format>” (7 bytes) –Modifies entry format for channels
Zero (0) value uses format defined by IR Type.
Add the total value for the formats below:
128 = Add Enter after channel number (105 + Enter)
64 = Add +100 to channel number (105 = +100, 05 –use 3 digit tuning)
3 = 3 digits (Ex: 007, 032, 105 –ICC1-IR inserts leading zeros, if needed)
2 = 2 digits (Ex: 07, 32 –ICC1-IR inserts leading zero, if needed)
1 = 1 digit (Ex: 7)
Ex: “$A5,<dh>,<dl>,3,’T3’, 131” Adds Enter, uses 3 digits for channel entry
Tips on using Channel Entry:
The IR Type setting includes a channel entry format normally used by the displays
in that control group. However, sometimes a manufacturer changes the entry
format for some models. Using the Channel Entry command, you can adapt to a
different entry format without changing your system programming. For example, in
the +100 Channel Entry mode, the ICC1-IR will receive a command for Channel 122
and translate that to a +100 command, followed by 22.
Note that the IR Type command sets a pre-defined Channel Entry format. If you
change or re-send an IR Type command to the ICC1-IR (or change with DIP
switches), you’ll need to send a Channel Entry again to add the modifications.

“$A5,<dh>,<dl>,2,’QT’,<channel>” (7 bytes) – Tunes channel if included in TR
Tune Ring
TR
“$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)
Locks power operation –only functional with display with power current sensor.
When the control is locked, the display is locked to the power state of the ICC1-IR.
For example, if the ICC1-IR power state is off, the display can’t be turned on from
the IR remote or TV front panel. The controller will sense the change from the
power sensor and turn the set off.
0 = Unlock, 128 = Lock
Tuning Style
H1=
“$A5,<dh>,<dl>,3,’H1’,<style>” (7 bytes)
1 = 5-digit CableCard style tuning (1-9999)
2 = Virtual HD Major-Minor tuning (tunes to virtual channel ID in display)
3 = Physical HD Major-Minor tuning (physical channel, minor digital)
TC Response
H2=
“$A5,<dh>,<dl>,3,’H2’,<response>” (7 bytes)
This pre-sets how the ICC1-IR will respond to TC tuning commands.
0= Ignore, use current settings
1= Analog Only (XX-0)
2= Digital (XX-1)
Tune HD
TH
Ex:
“$A5,<dh>,<dl>,5,’TH’,<H1>,<Major>,<Minor>” (9 bytes) – Digital Tuning
Normally, the H1 parameter is 0, allowing the ICC1-232 to use the current H1 tuning
format, but it could be used to force a different tuning option. When the display is
set to the H1=1 mode, 1-part digital channel, the first byte is (x*256), and the last
byte is the value you add to state the channel number. In H1=2 or 3 modes, the
bytes represent the Major and Minor channel numbers.
This command is designed for compatibility with other ICC controllers. In reality, H1
modes 2 and 3 are the same for IR control.
“$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

Special
Special commands for displays
Send IR
LQ=
“$A5,<dh>,<dl>,3,’LQ’,<IR Code>” (7 bytes)
Sends an IR pulse for special commands to the display. In Display Express the code
can be triggered by sending an HD channel command of 0-xxx (O-211 selects the
HDMI 1 input, 0-200 would return the TV to TV channel mode).
115=Captions
200=TV/Tuner
201=Video1
202=Video2
203=Video3
204=S-Video1
205=S-Video2
206=Component1
207=Component2
208=RGB1
209=RGB2
210=RGB3
211=HDMI1
212=HDMI2
213=HDMI3
214=HDMI4
215=HDMI5
LQ has other uses as well; it can trigger any IR code in the library. It’s similar to the
KK command in the 232-ATSC+1 manual. Refer to the code numbers on page 21
in the 232-ATSC+1 manual. For example sending LQ,25 will pulse a Volume Up
command, and LQ,25 is Volume down. If you’re using a custom control system,
repeat the command as long as the button is held down. The pulse itself will take
275ms.
Note: Not all commands are supported in different code sets, check with CR
Support to confirm operation. We will add codes as needed. Presently, the LG code
set 21 includes all the above commands.
IR Pulse
N1=
“$A5,<dh>,<dl>,3,’N1’,<Time>” (7 bytes)
Value 1-6 Sets pulse length in 100 millisecond time period. Typically, IR commands
are sent in a repeating pattern. A few TVs, such as some Visio models, will respond
to every repeat, so that channel 3-1 appears as 3311. Making the pulse shorter,
typically N1,2, fixes the problem. Sending an N1,0 command resets the controller
to the default pulse length.

iC-Net SmartZones
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)

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.

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 if you’re
using ICC2 2-way TV Controllers.
