connect to the DVR through the same ports as a conventional camera, but the control wires connect through the RS485 block on the back of the DVR. Picture 7-1, below, is only

a representation and your actual connector may look different. Please consult Chapter 2 Connections and Controls to find the diagram representing your model for the location of your connector block.

The RS485 connector uses a single-direction protocol meaning that it can send commands

You will need to consult your PTZ camera’s manual for details regarding protocol and baud rate. Please note that the DVR may support more features than your camera offers including protocol and number of preset programs.

out to the camera(s) but not receive any data back from the unit meaning that video images will be delivered through the video cable as with any other camera.

The DVR is set by default for RS485 to be disabled for each channel. Therefore, PTZ settings must be enabled before PTZ cameras can be utilized. This system supports 26 of the most common protocols including Pelco-D and Pelco-P.

When connecting a PTZ camera, the following should be taken into account:

•The 485 port of this DVR cannot parallel connect with the 485 port of another device

•The voltage between the A and B lines of the camera should be less than 5V.

Cameras can be individually configured or a global set-up can be implemented through the All button.

Simulative Cruise is for use with PTZ cameras using an unsupported protocol to allow you to use at least some of the features.
