Installation
AC Power
1. Insert DC power supply plug into 12 VDC jack on the VDC.
2. Plug power adaptor into AC wall outlet.
3. The Net LED should turn on and stay lit (indicates no network communication).
RF Coax and iCC-Net Operation
1. Connect the RF Coax cable into the Antenna/Cable input on the VDC.
2. If the iCC-Net signal is operating, the Net LED will blink once per second.
RS-232 Control Wiring
1. Attach the RS-232 cable to the VDC RS-232 Control connector.
2. Connect the cable to the video projector or display’s RS-232 control input.
A/V Setup
1. Connect audio and video outputs of the VDC into the audio and video inputs of the projector.
2. You may use the left or right audio output for a projector with mono audio, both for a TV with stereo audio (ICC2-VDC sound is mono).
3. Set the projector to its Video Input to view on-screen setup commands from the VDC.
Tip: At this point, you’ve set up the control wiring and the manufacturer’s commands sent will be programmed or changed with the On-Screen Setup Menu 45700. Press the Power button on the
VDC. If the Projector turns on and off, the settings are already correct.

External IR Sensor
The ICC2-VDC includes front-panel 38 KHz and 57 KHz IR sensors. An IR In jack is provided on the back for installation of an optional external IR-RXC IR Receiver. The external sensor, switchable for 38 KHz and 57 KHz sensing, can add IR coverage to the front sensors, or solve installation hurdles. Sometimes it’s hard to mount the VDC near the display and position the front-panel sensors for good IR reception. In addition, plasma displays radiate a fair amount of IR that could interfere with VDC IR reception.
1. Install the IR-RXC in a good location for IR reception.
2. Run the wire to the IR In jack on the VDC. a. Sleeve= DC power+ from power jack input, limited to less than 100mA b. Ring=DC power– (GND) c. Tip= IR data signal
3. Set the front-panel IR sensor to 38 KHz, 57 KHz, or off with On-Screen Menu command 45702 (page 8)
Programming the IC-RC Remote
In order to complete the setup of the VDC, you’ll need the IC-RC IR Remote to use the On-Screen Menus.
Typically, the remote is shipped ready to communicate to the VDC (Code 9). Just in case, here’s how to set the format of IR codes in the remote:
1. Press and hold the Select button and a numeric key for the code # below.
2. Release the two keys at the same time.
3. The remote will now send the selected codes.
4. Remote will keep the codes, even if battery power is lost.

Projector/Monitor Control Codes
The following chart includes the current RS-232 control codes for many brands and types of video displays.
While a manufacturer code set will control virtually all models in a given type or series, there are differences that arise, most commonly for baud rate, input selection, and options for internal tuner control. In addition, some models (especially for plasmas) may be OEM’ed from another supplier and use a different control code.
CR maintains a constantly-updated database on display makes and models – call our support team to confirm the best solution for your application.

RS-232 Terminal Commands
Overview
While the ICC-VDC is generally controlled through the RF using iC-Net commands, sometimes the tuner is used as a stand-alone tuner. For that application, the RS-232 port can be used for basic control and setup commands.
Communications parameters are fixed at 9600 baud, 8 data bits, No parity, and 1 stop bit. All settings are saved to NVRAM.
General protocol specifications
Characters in command strings to the 232-MTA are common ASCII keyboard characters. Command strings sent to the 232-MTA 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 232-
MTA begin with the ASCII < (less than symbol) as an 'Attention' character and end with a carriage return followed by line feed an ASCII LF or Hex $0A as 'End-of-command' characters.
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
Unit#
Command
Parameters
Return
Single character (>) starts the string
In general, use 0 (zero) – this will work regardless of the VDC device number
A two-character command
Added attributes to some commands
A carriage return ends the command string, you may use ASCII CR, Hex $0D, or keyboard
‘Enter’ in programming. For simplicity, the programming examples in the manual will not show the ‘CR’ – so remember, you’ll need to add it in your control code.
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.
RS-232 Command Hints and Tips
Leading zeros may be included or omitted from command parameters.
Example: ‘ >0TC=009’ Selects channel 9 as A/V output, same as ‘>TC=9’.
Multiple commands may be concatenated as single strings up to 120 ASCII characters long.
Example: ‘ >0VXTC=9’ Selects Mute A/V off, channel 9.
Example: ‘ >0S0=0S4=0’ Selects CATV mode, no front panel lockout.
Mute A/V Off command is not required in any command; however, it may be useful to send Mute A/V Off in case
Mute A/V had been set On from the front panel.
Sending all 3 status request commands to the ICC2-VDC back-to-back for a full status update is allowed.
Example: ‘ >0STSVSS’ Returns all 3 response strings back-to-back.
The carriage return line feed at the end of each ICC2-VDC response allows for easy monitoring of responses with an ASCII terminal program. You may use ASCII CR, Hex $0D, or keyboard ‘Enter’ in programming.
You don’t have to use the ‘=’ character between the command and parameter – the string works either way.

Character Generator Commands
The optional character generator supports an on-screen display that is 32 columns (characters) across by 13 rows (lines) down. An imaginary cursor represents the current screen write position. Writing text automatically increments the cursor to the next character space. The character text is always white.
TM=<label mode> Sets on-screen channel label mode.
0=None
1=Alpha only
2=Numeric only
3=Both alpha and numeric labels
Channel labels are displayed overlaying the video in the top-left corner of the screen for about 10 seconds after each channel change.
Example: '>TM=2' Sets channel mode to display channel number only.
TN=<channel>,<alpha label> Sets the alpha label for the specified channel. Alpha labels may be up to 8 characters and are displayed on screen when a channel changes, if alpha labels are enabled by the 'TM' command.
Example: '>TN=8,ABC' Sets the alpha label for channel 8 to be 'ABC'.

Keypad Channel Command
If you’re using an external control system, this command will emulate the pressing of numeric keypad buttons for channel selection, which means you won’t need to use extra elements for capturing channel commands in your programming. The KC command will access any channel, KT will only access a channel stored in the Tune
Ring.
KC=0 Emulates ‘0’ key, accesses any channel
KC=1
KC=9
KC
KT=9
KT
KD
Emulates ‘1’ key, accesses any channel
Emulates ‘9’ key, accesses any channel
Emulate ‘Enter’ key, accesses any channel.
Emulates ‘9’ key, accesses channel if it exists in current Tune Ring
Emulate ‘Enter’ key, accesses channel if it exists in current Tune Ring
Clears or cancels any KC or KT channel entry
After 3 seconds, with no other key, the selected channel will be tuned to. Optionally, you can have an Enter key send the command KC or KT to select the channel immediately. Using the KD command can cancel a channel entry before the time delay or Enter executes the channel change.
IC-RC Remote Emulation
You can also emulate IR commands sent from the CR IC-RC Wireless Remote. If you are using the numeric keys to select a channel, the user or program will need to follow the numeric command with an Enter.

iC-Net Control Protocol
Overview
RS-232 control for up to 4094 TV and Display Controllers is provided through an iC-series Head-End Network
Controller. The ICC-HE or ICE-HE Head-End receives the RS-232 or Telnet Ethernet commands and converts the data to a channel transmitted over RF coax, between a gap in channels 4 and 5.
Each Video Display Controller is assigned a unique device number from 1 to 4000 to which control commands are addressed. The devices are organized into 16 zones of 255 devices. All the devices in each zone will respond to a single “virtual device number” — one device number that represents all devices in each zone. There is also a global device number, 4095, that will command all devices in the system. This feature dramatically speeds up system operation and programming, because one command can affect an entire group of devices—or all. To take advantages of this feature, review the section iC-Net Zones in this manual.
In ABC Media Retrieval Systems, we reserve the first group of devices, 1-255, for components operating on a connected control system. Zones 1-16 are used for CR TV Controllers, Video Display Controllers and Tuners. As it’s unlikely any system will use all 4000 devices, this may be a good device standard for your system as well.
The Remote RS-232 port on the Head-End Network Controller can communicate from 1200 to 38.4K baud. The factory default setting is 19.2K baud, 8 data bits, No parity, and 1 stop bit.
Command String Structure
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 ‘$’ symbol
ASCII characters or strings are enclosed in single quotes
Numbers not marked as hex or ASCII are a single decimal byte
Parameters shown in < > brackets are single byte
A series of multiple commands or parameters are set apart by [ ] brackets
Commas separate the bytes, but are not part of the protocol
Double quotes enclose the command string, but are not part of the protocol
Command format:
“$A5,<dh>,<dl>,<ncb>,<cmd1>,<para> [<cmdN>]"
$A5
<dh>
<dl>
<ncb>
Starts the command
The zone or high order byte of the device (n times 256)*
The unit or low order byte of the device (number past dh - 0 for global zone)*
The number of command bytes to follow
<cmd1> The first command byte
<parameter> Command parameters (not used by all commands)
[<cmdN>] Multiple commands can be concatenated, with byte count added to <ncb>
*Device number example: $A5,2,4=Device 516 (256*2 + 4)

RS-232 Responses
iC-Net devices will send a response over the network whenever there is there is a change in status or command from an IR remote or front panel.
Response String Structure
Characters in response strings are expressed in a combination of hex and ASCII characters. For clarity, the following protocol examples use the following conventions:
ASCII characters or strings are shown enclosed in single quotes
Numbers shown that are not in single quotes are a single decimal 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 are not part of the protocol
Double quotes enclose the command string, but are not part of the protocol
Command format:
“ ‘<’,<dh>,<dl>,<nrb>,<rb1>, <para1> [<rbN>]"
‘>’
<dh>
<dl>
<nrb>
<rb1>
<para1>

K “ ‘<’,<dh>,<dl>,2,'K',<IR Key>" (6 bytes)
Sent when unit receives a new key command is pressed (10-116) or released (0) from the IR remote.
0 = Release
10 - 19 = Numeric keypad entry 0 – 9
21 = Enter
22 = Channel Up

29 = Menu
101 = Previous Channel
105 = Media Menu
106 = Cursor Right
107 = Cursor Left
108 = Cursor Up
109 = Cursor Down
110 = Media Select
115 = CC
116= Timer
The 0 – 9, Channel Up/Down functions are sent only if enabled in the TM command
(Bit 2 = 1). The Channel Up/Down responses will be sent if the Tune Ring contains no channels – see Ex2 in the Tune Ring command section.
M “ ‘<’,<dh>,<dl>,5,'M',<msh>, <msl>, <mph>, <mpl>" (9 bytes)
Sent when unit receives a new Menu command is pressed or released (0) from the IR remote. Menu Selection high and low bytes are in <msh> and <msl>. Menu Parameter high and low bytes are in <mph> and <mpl>.
A Menu command is initiated by pressing the Menu key, followed by a numeric entry, then the Enter or Channel Up key. During the Menu process, the Channel Down key acts as a backspace or delete key.
Some selections that need only a single numeric entry and will have a parameter value of zero (0). Those keys are 0, 8, 9, 18, 20, 30, 900, 911, and 912.
Menu selections that will prompt the user to enter a second parameter entry are:
1 = Select Media
2 = Password
3 = Chapter Search
4 = Frame Search
11 = Channel
21 = Page Zone
22 = Page Room
25 = Go
21 = Attach Zone
32 = Attach Room
Tip: The Menu entries are active even if the TV power is off.
SP " '<',0,0,4,'SP',<number devices present>,<number devices expected> (8 bytes)
Sent in response to HE status query.
Tip: If the number of present and expected devices match, the green Net LED on the
HE will blink once per second. If the two numbers do not agree, the LED blinks twice per second.
Contemporary Research 22 ICC2-VDC
iC-Net SmartZones
To simplify controlling groups of devices, iC-Net is divided into 16 zones of 255 devices, called
SmartZones. All the devices within each zone can be controlled simultaneously by sending a command to a single virtual device number.
For example, noting the zone chart below, if we send a Power On command to device #256, any TV controller numbered between 257 and 511 will instantly turn on. If we send a Power Off command to device #4095, all devices in the system will turn off.
This is an immensely powerful feature, because most systems can only address one device at time.
So if you need to turn off all 50 TV in a zone, you would need to send 50 commands. In addition to the hassles of creating multiple commands, there would be a long delay between the first and last command. One command, instant response is easier.
As we noted before, ABC Media Retrieval Systems reserve Zone 0 for devices used in the central control system, 1 -15 for iC-Net devices. This structure may be useful for your application, or you could use Zone 0 just like any other iC-Net zone.

Tip: You've probably figured out that you never want to assign a virtual device number to an
actual device in the system. If you assigned #1536 to a device, all the TV controllers in
Zone 6 would respond every time you sent a command to that one device.

System Map
One of the key tasks for iC-Net integrators is to create a logical System Map, assigning device numbers to TV controllers so they fall into physical zones useful to the client. The device mapping could be sorted by type or location; whichever suits the application.

Typical RF and ICC-Net Signal Flow
The diagram below shows the structure of a typical Contemporary Research media retrieval system. One of the key aspects for iCC-Net communication is to provide a forward and return (sub-channel) path for data.
Contemporary Research 25 ICC2-VDC
Mounting the VDC
In most cases, you’ll mount the VDC directly to the display, either below or above. Mounting below the display is preferred, as it’s usually the best location for IR reception from remotes, and helps to screen the internal IR sensors from stray ceiling-fixture IR.
With some video projectors, it’s hard to find the perfect location for control and IR reception for the internal IR sensors. In addition, many plasma displays emit a large amount of IR interference. In those situations, order the optional IR-RXC External IR Sensor, locating the sensor remotely from the display.
Installers commonly use Velcro to secure the VDC to the display. Others will use brackets, such as our optional RK2 Brackets to mount the VDC to the display, as shown below. Some combine the two approaches, using Velcro during the initial phase of installation, then securing with brackets when testing and troubleshooting is completed.
In all cases, it’s best to mount the VDC near to the display, simplifying wiring for A/V and control cables. If, for some reason, the VDC must be mounted in an equipment rack, you’ll need an optional
RK1 Rack Mount Kit.
