Overview
The ICE-HE-DXL Display Control Center is an intelligent soluon for “over-the-coax” RF display control to any combinaon of ICC1-
IRX Controllers, ICC1-232 Controllers, and ICC2-ATSC4S Tuner/Controllers. Control commands are sent over RF by inserng a micro
data channel in the gap between channels 4 and 5. In addion, its exibility allows it to communicate with individual displays,
groups, zones, or all displays using any one of three soware opons: the onboard DX Lite web page, Display Express Soware
from Contemporary Research, or third-party control systems.
DX Lite Web Page
The DX Lite web page can be congured to control up to 128 TVs, 24 channels, and 16 groups. No addional soware is required,
and the enre system can be controlled from any web-enabled device such as a smartphone or tablet.
Display Express Soware
By purchasing the addional Display Express Soware which resides on a PC, the Display Control Center can be expanded to sup-
port up to 4000 TVs and 256 channels. The soware oers increased exibility by providing the ability to dene presets, perform
advanced scheduling, congure mulple user levels, zones, etc.
Note: DX Lite does not convert to Display Express. The user must recongure the complete system with the new soware. If using
Display Express Soware, please refer to the “Display Express Soware Manual” for detailed instrucons.
Custom Control Systems
Custom control systems can connect to the Display Control Center through RS-232, front or rear panel USB, or Telnet, sending com-
mands via the published Contemporary Research ICC-Net protocol, controlling all TVs through a single control port.
Front-panel menus and the USB Service port simplify setup and rmware updates. In addion, a Display Express PC or other exter-
nal control system may be connected via the Ethernet, RS-232, or USB port on the back panel.
Note: The RS-232, front USB, and rear USB ports all perform the same funcon, but the front USB port is faster for rmware up-
dates.

Installation
Remote Control Connecon
There are three types of control ports:
• RS-232: Aach a null modem cable to the port. The default seng is 19.2K baud and can be changed via the front panel
setup.
• USB: Connect a mini-B USB cable from a Display Express PC or other control system. It shows up as FT230X UART in Win-
dows/Devices.
• Ethernet: Connect to an IP network port to access the internal DX Lite webpage, or use the port for telnet control or con-
necon to a Display Express server.
RF Coax and iCC-Net Operaon
• Connect an RF coax feed from RF Out to the system’s RF combiner, mixing the iCC-Net Out signal with the other CATV chan-
nels. The iCC-Net Out channel operates at 74.7 MHz, between cable channels 4 and 5.
• When combining the RF output with QMOD modulators, the internal aenuator should be set to 29 dBmV to match the
modulator’s level. 29 dBmV is the factory default seng.
• Do not connect any feeds to RF In in normal operaon. It is used only for legacy 2-way applicaons.
AC Power
• Insert the DC power supply plug into the Power In jack.
• Plug the power adapter into an AC wall outlet. The front panel display should turn on.
I/O Port
• Inputs are 0-24 VDC 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. Turning on the output turns on
the transistor and creates a current path to ground.

RS-232 Protocols for Custom Control Systems
Overview
RS-232 control for over 4000 TV Controllers is provided through an ICE-HE-DXL Display Control Center. The ICE-HE-DXL manages
ICC-Net communicaon over RF coax to ICC1-IRX and ICC1-232 Controllers as well as ICC2-ATSC 4S Tuner/Controllers.
Connecon from the control system can be made through the RS-232 Control Port or Telnet. The default seng for the RS-232
Control Port is 19.2K baud, 8 data bits, no parity bit, and 1 stop bit. For tesng purposes, a connecon can be made through the
front or rear panel USB mini-B connector from a Windows PC. This connecon will appear as a virtual COM port in Windows and
can be used with the IC Send soware from Contemporary Research or a terminal emulaon program.
Display Numbers
Each TV Controller is assigned a unique display number from 1 to 4094 to which control commands are addressed. The displays
are organized into 16 zones of 255 displays. All TV controllers in a zone will respond to a command sent to display 0. ALL TV con-
trollers will respond to a command sent to Zone 15, Display 255.

Command String Structure
All commands follow the same structure:
• An - Hex A5
• Zone - 1-15 (Hex 01-0F)
• Unit - 1-255 (Hex 01-FF)
• Bytes - Number of bytes that follow
• Command - 1 byte
• Parameters - 1 to 4 bytes

Page 15 ICE-HE-DXL User Manual 04/2018
Characters in command strings are expressed in a combinaon of hex and ASCII characters. For clarity, the following protocol
examples use the following convenons:
• Single-byte hex numbers are preceded by the ‘$’ symbol.
• ASCII characters or strings are enclosed in single quotes.
• Numbers not marked as hex or ASCII are a single decimal byte.
• Parameters shown in < > brackets are single byte.
• A series of mulple commands or parameters are set apart by [ ] brackets.
• Commas separate the bytes, but they are not part of the protocol.
• Double quotes enclose the command string, but they are not part of the protocol.
Command Format
“$A5,<dh>,<dl>,<ncb>,<cmd1>,<parameter>[<cmdN>]”
$A5 Starts the command
<dh> The zone or high order byte of the display
<dl> The unit or low order bye of the display (0 for global zone)
<ncb> The number of command bytes to follow
<cmd1> The rst command byte
<parameter> Command parameters (not used in all commands)
[<cmdN>] Mulple commands can be concatenated, with byte count added to <ncb>
String Format
Every soware applicaon has a dierent denotaon for handling hex, ASCII, and decimal formats. The examples in this manual
are in AMX format, which is understood by many in the control industry.
• Hex values begin with a dollar ($) symbol.
• ASCII values are enclosed in single quotes.
• Decimal values are shown as normal.
If using a mixed-format structure for commands, convert the symbols to the types required by your soware applicaon. For
example, a Tune Channel 2-3 command to display 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 denotaon) = 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
Note: When returning to normal eding mode, the app inserts an \x before each hex character.
