Net Zones
To simplify controlling groups of devices, iC-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, 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.
The ICC1-IRX and ICC1-232 controllers typical for many SignStream display control systems are designed to follow a Zone
address forma
t. You can use the 4 top switches in the second DIP switch (S2) to define the controller’s Zone. You could
stop at that point, or use the upper switches (S1) to define the controller’s address within the Zone. For example, setting
S2/1 On and S1/2 On defines that the controller is part of Zone 1 (256), and is the second unit in the Zone (2). The unique
address of the controller would be 258 (256 + 2)

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.
