iCC-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
iCC-Net address structure that includes device number 256
–
4095 that is divided up into 15 Zones.
To simplify controlling large groups of devices, iCC-Net is divided into 15 zones of 255 devices. 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 iCC-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.
