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.
