Basic Instructions for Integrating Display Express RF Control

Display Express is a very easy system to install and integrate, compared to other video distribution and control systems. Though it’s really simple, it’s often a new way of doing things for integrators. in this blog, we’ll lay out the basic steps, covering topics we see arising from those new to the technology. If you get the basic steps right, you’ll save a lot of time and effort caused by redoing the install correctly later on.

ICE-HE Ethernet Head End

ICE Install2

Install the ICE-HE Ethernet Head End first, as the unit sends a “Heartbeat” command over the RF network. If the RF data channel is correctly installed, all TV controllers have NET LED that will flash once a second. When you see the system “heartbeat” on the controller, you know it will respond correctly.

We advise using the RS-232 port whenever the PC that sends the control commands is in the same rack. It often takes some time for the IT team to reserve a static IP address. If you are using IP from a Windows server or remote custom control such as AMX, Crestron and others, the local RS-232 is handy for testing when the system is being installed.

Ethernet

The Ethernet port requires a static IP address, and the port only supports one Telnet session at a time. The Telnet protocol is identical for both RS-232 and Telnet. Commands are buffered, so you could use both ports at the same time. As the network static IP address may not active when you install, use the RS-232 port for testing until you have a valid IP connection. To define the IP port:

  • Use a Terminal app, Tera Term is a free app to use – you can use Telnet or RS-232
  • RS-232 settings are 19200 baud, 8 bits, no parity, 1 stop bit, no flow control
  • Commands are (use a Return at end of command)
    • Set Echo On in app, or enter <EN to echo what you enter
    • >IP   shows current settings
    • >IP= Enter new URL (NNN.NNN.NNN.NNN)
    • >IG= Enter the Gateway address
    • >IM= Enter the Subnet Mask address
    • Unit is preset to Telnet Port 2728

RS-232 Control

  • Use the Remote Control RS-232 port, using a Null Modem cable, Female to Female
  • 19200 baud, 8 bits, no parity, 1 stop bit, no flow control

Combining

  • Connect RF Out to an RF Combiner port, level is 55 dBmV
  • If combining with QMODs, use the included 20 dB attenuator
  • You can attenuate the RF level down by up to 10 dB turning the RF Out Adj screw on the front panel counter-clockwise
  • The micro control channel operates in the gap between channels 4 and 5, so it won’t affect other channels in your system

Testing

  • When you send a command to the Head End, the RX LED for the front-panel IP or RS-232 port should flash.
  • The COM LED should flash as well if the command’s basic structure is correct
  • The NET LED will flash twice each second
  • If you haven’t set up a Display Express PC as yet, or finished your control system commands, you can download our IC Send software from our Product page. That will allow you to send control commands to test control operation over IP or RS-232.

TV Controller Installation

Setting the Device Number

In the next step, you’ll need to set up the device number for the ICC1-232 or ICC-IRX. Turn the enclosure so that the DIP switches are on the bottom as shown.

ICC1 Switches

Switch S2 – Sets Zone number

  • The four Zone switches add multiples of 256 to all addressing of thousands of controllers
  • You can set up to 15 zones, from 256 to 3840
  • At least one of switches 1-4 must be on
  • Switches 5 and 6 must be off, 7 sets IR level higher for the ICC1-IRX

Switch S1 – Sets Unit Number

  • This is a standard binary switch. Just add the value from the 8 switches to define a number between 1 and 255
  • At least one switch must be on

Device Number

  • The controller’s address will be the total of both switches.
  • The address of the image above is 259 (3+256)

Geek Note: if you turn the enclosure around so the switches are at the top, you’ll see that Switch 1 is now a binary expression where the first switch =128 and the last =1. Might be easier to use that way if you’re more comfortable with binary numbers. 

Zones

You can create up to 15 zones of controllers in this fashion. For small sites, you may want to set all controllers to Zone 1 (256). In larger installs, you can use the Zones to define pre-set groups for the controllers. Using Zones, you can send one command that is repeated by all controllers in that group.

  • Zone 1 (256) – All controllers between 257 and 511 will respond to the command
  • All Zones (4095) – All controllers will respond to the command

Most dealers will pre-configure the controller’s address before hanging displays – and some do this at the site. EIther way, you need to plan the addresses and names you want to assign to each controller You can download a TV Installation spreadsheet here – Display Express TV Worksheet .

Code Sets

All TV Controllers will be shipped with the TV code set marked on a label so you can match the controller to the right TV.  We repeat the instructions for the device address on that label – and there is space for you to add the TV address and location. They are shipped with a default number for testing, which you’ll change in the field.

ICC1-IR controllers have the full library of IR codes onboard. It will be set for the code you specified, but you can send a command to select a different code. ICC1-232 controllers have one code set installed. You can update or change the code later by updating the controller firmware.

ICC1-232 RS-232 TV Controller Installation

ICC-Install

  • Connect the system RF feed into RF In (the unit picks off the control channel and passes the rest on)
  • Connect RF Out to the TV’s Antenna/Cable input
  • Connect the RS-232 cable to between the controller and TV – most use a DB9F null modem cable, a few use a DB9F to 3.5mm stereo mini cable (CR has both kinds)
  • Add power to the unit, NeT LED should flash once per second if ICE-HE is active on the RF network

ICC1-IRX IR TV Controller Installation

ICC1-IRX Install [Converted]

  • Connect the system RF feed into RF In (the unit picks off the control channel and passes the rest on)
  • Connect RF Out to the TV’s Antenna/Cable input
  • Connect the included IR emitter to the IR Out connector
  • If you’re using the Xantech CSM1 to sense the AC current, connect it to the CSM1 input (no other accessory needed)
  • If you have an old analog tube TV, we have an optional CC-HSD that senses the EMI from the cathode. Connect to Tip+ and move the sensor cube around the back of the TV until the red LED lights
  • Add power to the unit, NeT LED should flash once per second if the ICE-HE is active on the RF network

ICC2-ATSC Series TV Tuner/Controllers

ICC2-ATSC RF Wiring

You will set the address of the tuner via menus rather than switches, but the idea is the same. One menu sets the unit address from 1-99, and the next menu sets the Zone # from 1-15 (multiply the Zone # by 256). Refer to the product manual for instructions.

TV Control Tips

  • NEC RS-232 – One of the reasons we ask for TV makes and models when TV Controllers are ordered is there are several NEC code sets that vary by model. For example, E-series TVs have one code set, but a slightly different set for 70” and above TVs with the plug-in AVT tuner.
  • Samsung Commercial TVs. The RS-232 code set is the same for all TVs, but some models use a DB9 connector and others use a 3.5mm jack
  • Samsung IR – the basic IR code set works for almost all Samsung TVs. There are a few models that use different discrete codes than others, alternative codes are in the IRX library – you many need to update the firmware for exisiting ICC1-IR and ICC1-IRX controllers to access the code sets. Check with CR Support when you find this problem
  • Sharp RS-232 – Sharp RS-232 has a known bug that pops up now and then. The symptom will be that you can access channels with a minor address of 2 and above – but when you access a .1 channel such as 5.1, the TV will bounce back to the previous channel. Sending an H9,1 command via Display Express, IC Send or your control system to the problem TVs will fix the issue.
  • Sharp RS-232 EnergyStar – By default ( for Energy Star) Sharp turns off the RS-232 port when the TV is off – you can’t turn it on. The fix is to turn on all the Sharp TVs with the IR remote. Send an ON command from DX or your software to all TVs. We include a code that keeps the RS-232 port active
