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.

ICE-HE-DXL Setup
Basic Network Setup
• Connect the Display Control Center to the network.
• Press the red SETUP buon.
• Press the Down arrow unl “Network” is displayed then press the white SELECT buon.
• Use the Down arrow to view “IP Mode”.
• Use the Le or Right arrow to show “DHCP” then press the SELECT buon to save the seng.
• To create a stac IP address, choose “Stac” mode and manually set an IP address. The unit will use the gateway sengs it cap-
tured in “DHCP”.
• Press SETUP then SELECT to show the IP Address.
• A PC’s Ethernet port may be directly connected to the ICE-HE-DXL’s Ethernet port. A cross-over cable is not required.
• Enter the IP Address of the ICE-HE-DXL into the top entry bar on your browser.
• The DX Lite home page will appear on your screen.
• If the ICE-HE-DXL is connected to a network with Wi-Fi access, the unit may also be accessed from the browser on a tablet or
smart phone.

Front Panel Display
During normal operaon, the ICE-HE-DXL displays the above text on the LCD display. The top line shows communicaon ports as
well as network and control status. “Rx” or “Tx” appears briey under the three external ports (232, USB, IP) to show I/O acvity,
and a white cursor will blink under the three status opons (Network, Communicaon, Error).
• 232 – Acve RS-232 port
• USB – Acve USB data port
• IP – Acve Ethernet port
• N – ICC-Net status, blinking once per second, sending the “heartbeat” command to all TV controllers.
• C – Valid ICC-Net command. The processor evaluates the syntax, and conrms when it is valid.
• E – Error in ICC-Net control frequency. The unit auto-corrects the frequency, so you may see the error status briey, such as
when the unit is powered up. If the status stays constant, contact CR Support for service.
ICE-HE DXL Setup Menus
Press the SETUP buon to enter the menus. Use the Up/Down arrows to move through menus and the Le/Right arrows to
change sengs. Press SELECT to store the changes at each step.
• Select a menu group (“System”, “Network”, “Command”) then SELECT to view that group’s menus.
• Press SETUP to move back to other menu groups.
• Pressing the Le/Right arrows together will reboot the unit.

Note: In the version of rmware available at this me, the “Send 232 Typ” command is supported only with the ICC2-ATSC 4S Tuner/
Controller. It is not yet funconal with the ICC1-232 Controller.
Send IR Type / Send 232 Typ Commands
In the Command secon of the menu above, Send IR Type and Send 232 Typ are used to match the controllers to the specic TV
models and locaon on the network. There are three parts to the command, selected by moving the Le/Right arrows to each
value, then using the Up/Down arrows to set a number. Press SELECT to store the changes.
The following is a descripon of those commands.
All ICC-Net controllers have a display ID that is made up of two values: Zone and Unit. The displays are organized into 16 Zones of
255 displays each. The display number is equal to the Zone number plus the Unit number. For example: Display 258 is Unit 2 (2)
of Zone 1 (256).

Zn: Press the Right arrow to select the Zone, use the Up/Down arrow to select the Zone number.
Zn = (0-15, or ALL). ALL TV Controllers will respond to a command sent to Zone ALL.
Un: Press the Right arrow again to select a Unit number
1-255 or ALL (all the controllers in that Zone)

Display Express Lite
The Display Express Lite web page in the ICE-HE-DXL Display Control Center is a compact version of full Display Express soware
that runs on a PC. The Lite version is focused on one task – tuning channels for a selected group of TVs, with the added opons for
TV power and volume, and turning all the TVs on and o.
The page will scale to t your screen, whether on a smartphone, tablet, or PC.
