1. Connections

RS485 network connection diagram

To connect multiple cameras by RS485, the cameras are attached to a 2-wire twisted pair bus (max length

1200m) that is terminated at both ends with a 120 Ω impedance resistor. The maximum distance from the bus

to the camera or controller is 5m.

Addressing Multiple Cameras

In case more cameras are connected to the controller, each camera needs to be addressed the right way to a

camera number of the controller.

The following settings need to match in both camera and controller:

Protocol (VISCA, PELCO-p or PELCO-d)

Camera address number (1, 2 or n)

Communication settings as baud rate (9600), parity, etc.
