To simplify controlling groups of devices, iC-Net is divided into 16 zones of 255 devices, also 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 SmartZone 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.

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.
