Main controller

Daisy-Chain connection WITH SHORT SPURS for the RS485 PTZ control signal

(one main radial with very short spurs to each dome off it, keeping the spurs to less than 10 meters)

TIP - The connection of a 120 termination resistor: The termination resistor is ready fitted on the

domes pcb, all you have to do set it is move the jumper from Pins 2 &3 to pins 1 & 2.

STAR method of connection.

In some circumstances you may need to adopt a star configuration for practical purposes. For instance, all the

domes may be so scattered on a large site that running out separate spurs to each dome in a “STAR” array is

the only practical solution.

So how do you do this in practice?

The termination resistors must be connected to the two domes that are farthest away from each other,

Special Note:

The jumper and dipswitches are

located on the top of the dome

head. To access them push the

dome module up and twist to

release and you will see the

switches as per diagram on the

left.
