Overview
The ICE-HE-DXL Display Control Center is an integral component of the iCC-Net over-the-coax RF display control solution. The unit is the
required interface between an AV control system and the ICC1-IRX and ICC1-232 display controllers and the ICC1-TC tuner/controllers. The
unit receives the iCC-Net control command data from the control system and processes it for transmission in a narrow band RF signal in the
gap between RF channels 4 and 5. Control command data may be received by TCP over the Ethernet connection or RS-232 via the DB-9
connector or USB virtual com port.
iCC-Net Control commands may originate from a Display Express server PC, the embedded Display Express Lite web page, or a third-party
control system.
An on-board web server hosts the Display Express Lite control software. The software is accessible using an internet browser from a tablet,
smart phone, or computer. The software is easy to configure and may be used for control of up to 128 display controllers or
tuner/controllers. Control functions include power on/off, volume and channel selection from up to 32 source channels.
The ICE-HE-DXL may also be used as the control interface in a hybrid RF/IPTV or IPTV only distribution system along with QIP-D or QIP-DVX

Setup Notes
Interfacing with a Control System
The unit may receive iCC-Net command strings from a Display Express server PC or a third-party control processor. The command strings
may be received at the following interfaces.
•TCP at port 2728
•RS-232 via the DB-9 port
•RS-232 via either USB virtual com port
Only one TCP socket is supported. The buffered data bus allows for commands to be received concurrently from any of the interfaces.
Display Express Lite
The ICE-HE-DXL includes an embedded web server that hosts the Display Express Lite web page. Display Express Lite supports basic control
of power, volume, and channel selection for any combination of up to 128 display controllers, tuner/controllers, or IPTV
decoder/controllers. The web page may be accessed from the web browser of a connected device either wired or through a Wi-Fi access
point.
IP Network Settings
The IP Address, Default Gateway, and Subnet Mask may be set in the front panel Network menu or via RS-232 command. The current IP
address may be displayed on the front panel by holding the Setup button. The default IP address is 192.168.1.251. Changes to any of
network settings require a power cycle or reboot.
RS-232
The DB-9 RS-232 port may be used for control, configuration, and firmware updates. The baud rate settings apply to the DB-9 RS-232 port
and the rear panel USB virtual com port. Baud Rate settings are available in the front panel System menu or may be changed via RS-232 or
telnet serial command. The default baud rate is 19,200. Changes to the baud rate setting is instantaneous and no power cycle or reboot is
required.
USB Virtual Com Ports
The front and rear panel USB virtual com ports may be used for control, configuration, and firmware updates. Windows 10 will
automatically load the appropriate driver. The baud rate setting applies to the rear panel USB port. The baud rate for the front panel USB
port is fixed at 115.2K.
UDP Control
The iCC-Net commands that are transmitted via the RF output may be duplicated and transmitted as UDP directed broadcast data packets
for control of QIP-D and QIP-DVX IPTV decoder/controllers and 232-ATSC 4i and ATSC-SDI 4i HDTV tuners. This function may be enabled or
disabled in the front panel menu or via RS-232 command. It is enabled by default.
I/O Port
Inputs may accept a 0-24 VDC control voltage or contact closure to ground. A closed contact closure creates a logical low, an open contact
closure creates a logical high.
Outputs are open collector and may require a pull-up resistor; 28 VDC max, 200 mA max. A logic level high turns on the transistor and
creates a current path to ground.
Simplified Output Circuit
Typical Application

Page | 8 ICE-HE-DXL Display Control Center Product Manual 042021
RF Output Level
The RF output will be connected to the input of a combiner to insert the iCC-Net data channel into the RF distribution system. The RF
output level adjustment has a range from 14 to 45 dBmv. The default setting is 29 dBmv. The RF level should be set to match the level of
the modulators or CATV channels as they enter the combiner. Typically, when used with QMOD modulators, the RF output level will not
need to be changed as the QMOD default RF level of 29 dBmv matches the default RF level of the ICE-HE-DXL.
RS-232/Telnet Two-Way Communication Protocol
The ICE-HE-DXL full duplex RS-232/Telnet protocol is available for configuration and status monitoring. All commands are sent as ASCII
strings. No delays between characters or commands are required, as data is interrupt driven and buffered.
Communications parameters are 1200 to 230,400 baud, 8 data bits, no parity, and 1 stop bit. Factory default is 19,200 baud. All settings are
saved to NVRAM in the decoder. The RS-232 port will accept non-standard control such as voltage that swings from 0 to +5 VDC, commonly
found when IR ports are used to send RS-232 commands.
The same commands can be sent over IP Telnet (up to two sessions). The default telnet port is 23.
General Protocol Specifications
Characters in command strings to the ICE-HE-DXL are common ASCII keyboard characters. Command strings sent to the ICE-HE-DXL begin
with the ASCII > (greater than symbol) as an ‘Attention’ character and end with carriage return - ASCII CR, Hex $0D, or keyboard Enter - as an
‘End-of-command’ character.
Responses from the ICE-HE-DXL begin with the ASCII < (less than symbol) as an ‘Attention’ character and end with a carriage return followed
by a line feed - ASCII LF or Hex $0A as an ‘End-of-command’ character.
A carriage return is required at the end of each command and is assumed in all examples.
Command String Structure
[Attention][Unit #] [Command] (Parameters) [Return]
Attention Single character (>) starts the string
Unit # The unit number is fixed at Unit #1, omitting unit number will default to Unit #1
Command A two-character command
Parameters Added attributes to some commands
Return A carriage return ends the command string. ASCII CR, Hex $0D, or keyboard ‘Enter’ may be used in programming. For
simplicity, the programming examples in the manual will not show the ‘CR’.
Command and Status Response
Commands can be sent back-to-back at any time without any delay. To allow for rapid, multiple commands, status responses are
intentionally delayed by about 125mS, sending the most current status in response to control commands or user actions.
String Example
The example below is a command to set the subnet mask followed by the response string.

iCC-Net Control Overview
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 display controllers, HDTV
tuner/controllers, IPTV decoder/controllers, and HDTV tuners.
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.
The command string data is modulated and transmitted over a low bandwidth RF data channel. The data channel is at 74.7 MHz in the gap
between channels 4 and 5. The RF output of the ICE-HE-DXL is combined with the CATV channels at the head end prior to distribution.
When connected to an IPTV network, the ICE-HE-DXL will simultaneously send the same iCC-Net command strings as a UDP broadcast data
packets for control of compatible IPTV decoder/controllers and HDTV tuners. This allows for the creation of hybrid RF/IP systems with
seamless control.
Building an RF Based Control System
The RF based system will comprise of a control system interface to execute the commands, an ICE-HE-DXL Display Control Center, and any
combination of display controllers and tuner/controllers.

•Third-party control processor
The ICE-HE-DXL Display Control Center is required to process the iCC-Net data from the control system and allow it to be inserted into the
CATV RF distribution system.
Display control is accomplished using display controllers and HDTV tuner/controllers. Display controllers and tuner/controllers in any
combination are utilized to receive the iCC-Net command strings and process the display specific commands for display control.
The display controllers have an RF pass-through for connection to the display’s integrated tuner. The tuner/controller replaces the function
of a display’s integrated tuner for receiving and decoding the CATV channels in addition to provided display control. The display controllers
or tuner/controller include the following listed below.

iCC-Net Protocol
The main components of the iCC-Net command string include the display device number, the command, and command parameters if
required.
Explanation of 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.

Command String Protocol
“$A5,<dh>,<dl>,<ncb>,<cmd1>,<parameter>[<cmdN>]”
$A5 Starts the command
<dh> The zone or high order byte of the display device
<dl> The unit or low order byte of the display device (0 for global zone)
<ncb> The number of command bytes to follow
<cmd1> The first two-character command
<parameter> Command parameters (not used in all commands)
[<cmdN>] Multiple commands can be concatenated, with byte count added to <ncb>
Characters in command strings are expressed in a combination of hex and ASCII characters. For clarity, the following protocol examples use
the following conventions:
•Single-byte hex numbers are preceded by the ‘$’ 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 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.
A Decimal/ASCII/Hex conversion chart may be found at www.asciitable.com .
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.
