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.

Zone Device # Unit Total Device #

1 256 1-255 257-511

2 512 1-255 512-767

3 768 1-255 769-1023

5 1280 1-255 1281-1535

6 1536 1-255 1537-1791

7 1792 1-255 1793-2047

8 2048 1-255 2049-2303

9 2304 1-255 2305-2559

10 2560 1-255 2561-2815

11 2816 1-255 2817-3071

12 3072 1-255 3073-3327

13 3328 1-255 3329-3583

14 3584 1-255 3585-3839

15 3840 1-255 3841-4000

All Zones 4095

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.
