iC-Net Zones, Units and Device Addresses
In the front-panel setup instructions, you set the Unit # (1-255), then the Zone # (1-15). This refers to the
iC-Net address structure that includes device number 256 – 4095 that is divided up into 15 Zones.
To simplify controlling groups of devices, iC-Net is divide,d into 15 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, all iC-Net
controllers in Zone 1 will turn off at the same time.
This is an immensely powerful feature, because most systems can only address one device at time. 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.
The Zone number plus the Unit number equals the actual device address.

Tip
:
While many applications can use just the Zone number, it’s a good practice to assign a unique Unit
number to each controller in the zone
.
This allows the system software to address individual controllers
if necessary.
