ICE-HE-DXL Display Control Center Product Manual 042021
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.
