Communication Cable
Cable requirements for RS-485 communication are as follows:
- Shielded Twisted Pair (STP) Cable
- Low Impedance
- Gauge greater than AWG #22 (0.33
mm
2
)
6. Communication Setup
Camera Address Setup
Use SW606, SW605, and SW604 to specify the camera address.
You can specify between 0 and 255 for the address, where the hundreds digit is
with SW606, the tens digit with SW605, and the ones digit with SW604.
ex) Camera address: If the address is 1, follow the steps in the fi gure below.

Termination
If a number of cameras are connected in a daisy chain* confi guration as shown in
the connection diagrams below, the last camera must be RS-485 terminated by
using Rx and Tx. (*Daisy Chain: A daisy chain is a means of connecting a number of
devices to each other in series. For example, Camera 1 is connected to Camera 2,
and Camera 2 is connected to Camera 3, and so on.)

Connection Diagrams
Although you can connect up to 128 cameras, connecting less than 32 cameras
ensures the best communication environment.
A communication error may occur if you connect multiple cameras that are assigned
the same address in the network.
