Overview
The Contemporary Research ICC1-TC Tuner/Controller is a full featured ATSC/NTSC HDTV tuner with an integrated display controller. The
ICC1-TC will tune ATSC air, clear QAM cable, and NTSC air and cable channels. The low-profile design allows for mounting behind flat panel
displays.
The ICC1-TC Tuner/Controller features an HDMI output with video scaling from 480i to 2160p.
Front panel controls are available for channel selection, volume, power, and menu. The unit may also be controlled by the optional HD2-RC
IR remote via the front panel IR sensor or remote IR sensor connected to the rear panel IR port.
When used as part of an RF based iCC-Net control system, the tuner will respond to power, channel and volume commands and the
integrated display controller may be used to control power and source selection on the connected display device. The ICC1-TC
tuner/controller has an onboard control database of RS-232 protocols for many common flat panel displays and video projectors. The
display type may be selected when configuring the unit.
The iCC-Net commands are received over the same coax cable as the source channels from an ICE-HE-DXL display control center. The
control interface may be the Display Express Lite application included with an ICE-HE-DXL Display Control Center, Display Express software,
or a third-party control system.

Installing the ICC1-TC
The slim profile of the ICC1-TC allows for mounting behind a flat panel display. The unit may be attached to the flat panel display with user
provided hook and loop fastener adhesive tape or attached to the wall using the mounting ears. The unit may also be set flat on a suitable
shelf or other stable flat surface.
Connect the HDMI output to a video display. Analog and SPDIF digital audio outputs are available for connection to an amplifier or audio
system processor. Connect a coaxial cable from the CATV or antenna source to the RF in connector. Connect the supplied short coaxial
cable from the RF out to the Air/Cable input. The ICC1-TC will need to be connected to an appropriate power source.
After the ICC1-TC is connected, a channel scan will need to be performed prior to viewing programs. The channel scan may be initiated in
the on-screen text A/V menu, the on-screen graphical menu, or iCC-Net command.
ICC1-TC Control and Setup
The control and setup functions of the ICC1-TC may be accessible by:
 On-Screen menus accessible from front panel or handheld IR remote
 One-way iCC-Net protocol commands delivered over the coax through an ICE-HE-DXL display control center

Setup Notes
Channel Scan
A channel scan will be required prior to initial use and subsequently following any changes to the received channel line-up. The channel
scan may be initiated in either on-screen setup menu or by iCC-Net command. The Air or Cable scan mode should be selected for the
intended application prior to initiating the scan.
Tuning Cable Channels
The ICC1-TC will skip encrypted channels automatically during a channel scan. The scan of analog channels may be skipped by pressing
Select after the scan has started. Typically, the digital channels will not use the same Guide numbers as a cable box.
Air/Cable
The ICC1-TC has separate channel memories for air and cable channels. It is possible to toggle between the two channel memories. A
separate channel scan for each mode will be required. The toggle may be initiated by simultaneously pressing the Up and Down buttons on
the front panel or pressing the A/C button on the IR remote.
DVI
Compatibility with DVI displays is normally supported and automatically detected. Forced DVI may be manually selected from the HDMI-DVI
menu setting.
Audio
The HDMI digital audio format may be selected as AC-3, PCM or PCM variable. The volume settings do not affect HDMI digital audio in AC-3
or PCM modes. PCM Variable supports volume control on all audio outputs. The analog audio outputs always follow the volume control
settings. If there is no audio, make sure the volume is all the way up (and not muted). A “motorboat” sound means the display does not
support AC-3, and the mode should be changed to PCM.
IR Control
 Interference from room fluorescent lights can cause problems with IR remote operation. If this occurs, the frequency of the IR may
be changed in the HD2-RC remote. Hold Select and press “9” to set the IR frequency at 57 KHz. Hold Select and press “4” to set the
IR to the normal 38 KHz frequency.
 If there is significant IR interference, an IR-RXD Remote Sensor may be required. Cover the front-panel IR sensor to reduce
interference.
 Disabling the IR sensor in the configuration settings will disable the front panel IR sensor and the rear panel IR In jack.
 The ICC1-TC will respond to a universal remote with the TV type set to Sharp.
Restore Factory Default Settings
The unit may have the configuration restored to the factory default settings. The channel list is not changed as this data is stored in
separate memory.
The factory default settings may be restored using the on-screen text menu. Hold the Menu button to open the on-screen text menu.

iCC-Net Control Overview
The ICC1-TC tuner/controller may be configured to be used as a component in an iCC-Net control system. iCC-Net is a unique and
proprietary control command protocol from Contemporary Research for sending one-way control commands to display controllers, HDTV
tuner/controllers, IPTV decoder/controllers, and HDTV tuners over new or existing video distribution infrastructure. Separate dedicated
control wiring for each component is not required. The user will be able to control the content on the displays via channel commands as
well as volume and power. The video distribution system may be CATV channels delivered over coax, MPEG-TS IPTV streams delivered over
an Ethernet network, or a combination of both.
The structure of the iCC-Net protocol command strings allows for independent control of large numbers of ICC1-TC tuner/controllers. The
integrated display controller will handle processing display related commands for control of the display.
For RF based CATV applications, an ICE-HE-DXL display control center is required. The RF output of the ICE-HE-DXL carrying the control data
is combined with source channels to be distributed through the RF system. The control interface for the ICE-HE-DXL may be the embedded
Display Express Lite web application, a Display Express server PC, or a third-party control system. Each iCC-Net device will be assigned a
display device number. As the command strings are broadcast to all devices on the distribution network, a device will only respond when it
receives a string with a device number value that matches its configured device number. All other devices will ignore the command string.

iCC-Net Control Data Flow with RF System Using Third-Party Control

Page | 16 ICC1-TC Tuner/Controller Product Manual 082020
Integrated Display Controller
The ICC1-TC supports sending control commands to the connected display using RS-232 or HDMI CEC. The power state of the display will
follow the power state of the ICC1-TC.
When used as part of an iCC-Net control system, additional display control functions are available. For RS-232 controlled displays, the
control functions include power, source selection, and the ability to pass through custom RS-232 strings from the control system.
Display control will need to be enabled in the on-screen text System menu or via RS-232 command. The options are HDMI CEC or RS-232. If
RS-232 is selected, the RS-232 port will only function as transmit only to control the display.
The RS-232 protocols for many common TV and display makes and models are built in to the ICC1-TC application firmware. If a desired
display type is not listed, contact Contemporary Research support for assistance.
HDMI CEC Control
HDMI CEC may be selected for sending power commands to the display. No other control functions are available for CEC control. HDMI CEC
sends standardized control commands over the HDMI cable. CEC functionality is available in many TVs and displays designed for the
consumer market. If control of the TV or display via HDMI CEC is desired, it is important to check the TV or display’s documentation to
determine if CEC is supported.
It is common for manufacturers to use their own unique term to refer to HDMI CEC. For example, Samsung refers to CEC as Anylink. LG
refers to it as SimpLink.
CEC will likely need to be enabled in the display. Some displays will automatically detect that a CEC supported device has been connected
and prompt for confirmation.
Although the industry strives for standardization relating to CEC, it is possible that some or all CEC control communication between the
ICC1-TC and connected display may not function depending on display make and model. In this situation, RS-232 is recommended for
reliable display control.
RS-232 Display Control
One-way RS-232 display control is available through the rear panel DB-9 RS-232 port. The RS-232 port may be used to send commands for
power and input source selection. When used with Display Express or a third-party control system using iCC-Net protocols, it is possible to
forward custom RS-232 strings to the display.
The connection to the display should be with an RS-232 null modem cable. Most displays with a 3.5mm RS-232 port are compatible with the
optional Contemporary Research CC-COM 3.5 (5061-009) serial cable. Typically, displays from LG with a 3.5mm RS-232 port require a DB-9
male to female null modem adaptor (5061-012) if used with the CC-COM 3.5 serial cable or equivalent.
The RS-232 display (TV) type will need to be selected via the on-screen text menu or RS-232 command. Refer to the table for a list of the
supported display types. If the desired display type is not listed, contact Contemporary Research support for assistance. The com port
parameters will automatically be changed to match the requirements of the selected display type unless otherwise noted.

iCC-Net Protocol Format
The iCC-Net command string includes the display device number, the command, and command parameters if required.
Display Device Numbers
A unique display device number from 1 to 4094 is assigned to each TV controller, tuner controller, QIP-D decoder/controller, QIP-DVX
decoder/controller, or tuner to which control commands are addressed. The displays are organized into 16 zones of up to 255 devices each.
The Zone/Unit concept is used with Display Express, Display Express Lite, and when writing command strings for third-party control systems.
Display Express Lite is limited to 128 display devices in zone 1. Unit numbers are restricted to the range of 1 to 128 corresponding to display
device numbers 257 to 384.
The display device number is represented in the iCC-Net command string by the zone number and the unit number. The hex equivalent of
the zone number and the unit number is equal to the hex equivalent of the display device number.
Example:
Zone 3 = hex 03
Unit 201 = hex C9
Display Device 969 = Hex 03 C9
The device number can be calculated in decimal using the formula ‘(zone number x 256) + unit number = display device number’.
All display controllers in a zone will respond to a command sent to unit number 0. All display controllers will respond to a command sent to
Zone 15, Unit 255.
Zone # Zone x 256 Unit # Display Device #
0 0 1-255 1-255
1 256 1-255 257-511
2 512 1-255 513-767

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 the decimal equivalent of a single hex byte.
 Parameters shown in < > brackets are single hex byte.
 A series of multiple commands or parameters are set apart by [ ] brackets.
 Commas separate the bytes, but they are not part of the protocol.
 Double quotes enclose the command string, but they are not part of the protocol.

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 ($) symbol
 ASCII values are enclosed in single quotes
 Decimal values are shown as normal
When planning to use a mixed-format structure for commands, convert the symbols to the types required by your specific software
application. For example, a Tune Digital Channel 12-3 command to display device 280 could be shown several ways:
 AMX Mixed Format = “$A5,1,24,5,’TH’,2,12,3”
 AMX Hex Format “$A5 $01 $18 $05 $54 $48 $02 $0C $03”
 Standard Hex (no denotation) = A5 01 18 05 54 48 02 0C 03
 Crestron Hex Format = \0xA5\0x01\0x18\0x05\0x54\0x48\0x02\0x0C\0x03
 RTI = Select port, Hex mode, enter A5 01 18 05 54 48 02 0C 03 - Note that when you go back to normal editing mode, the app
inserts a \x before each Hex character.

Table of iCC-Net Control Commands
Code Function Operation
Power
P1 Power On "$A5,<dh>,<dl>,2,'P1'" (6 bytes)
P0 Power Off "$A5,<dh>,<dl>,2,'P0'" (6 bytes)
PT Power Toggle "$A5,<dh>,<dl>,2,'PT'" (6 bytes)
LM Control Lock "$A5,<dh>,<dl>,3,'LM',<Control>" (7 bytes)
Locks out ICC1-TC control from an IR remote or front-panel buttons.
<Control> Total value of control options below
0=Disabled
1=Front panel button lockout enabled
64=Volume control lockout enabled
128=IR remote sensor disabled
Example:
"$A5,6,124,3,'LM',193" Device 1660, Locks out all control
Channel Selection
TH Set Digital Channel "$A5,<dh>,<dl>,5,'TH',<H1>,<Major>,<Minor>" (9 bytes)
Sets digital channel with one-part virtual channel numbers and two-part channel numbers up to 255-
255
<H1> Tuning Style
0=No Change in tuning style
1=Five digit one-part channel (Major=high byte, Minor=low byte)
Formula: (high byte x 256) + low byte = channel number
2=Two-part virtual channel number (Major-Minor)
3=Two-part physical channel number (Major-Minor)
Examples:
"$A5,1,4,5,'TH',2,2,3" Device 260, virtual channel 2-3
"$A5,1,4,5,'TH',1,1,69" Device 260, channel 325 (256+69)
TJ Set Digital Channel "$A5,<dh>,<dl>,6,'TJ',<Major high>,<Major low>,<Minor high>,<Minor low>" (10 bytes)
Sets digital channel with two-part virtual channel numbers up to 999-999
Formula: (high byte x 256) + low byte = channel number
Example:
"$A5,2,44,6,'TJ',1,40,0,1" Device 580, channel 296-1
TC Set Analog Channel "$A5,<dh>,<dl>,3,'TC',<Channel>" (7 bytes)
H1 Tuning Style "$A5,<dh>,<dl>,3,'H1',<Style>" (7 bytes)
Sets the tuning style used with the TH channel command. This setting is stored in memory and only
needs to be sent one time. Subsequent TH channel commands may have the <H1> byte set to 0.
<Style>
1=Five digit one-part virtual channel number
2=Two-part major-minor virtual channel number
3=Two-part major-minor physical channel number
