RS485

When the DVR receives a camera control command, it transmits that command up the coaxial cable to the PTZ device. RS485 is a single- direction protocol; the PTZ device cannot return any data to the unit. To enable the operation, connect the PTZ device to the RS485 (A,B) input on the DVR. See Figure 3-3.

Since RS485 is disabled by default for each camera, you must enable the PTZ settings first. This series DVRs support multiple protocols such as Pelco-D, Pelco-P.

To connect PTZ devices to the DVR:

1.Connect RS485 A,B on the DVR rear panel.

a.Ensure the decoder has the same grounding with the DVR, otherwise you will not be able to control the PTZ. Shielded twisted wire is recommended, and the shielded layer should be used to connect the ground.

b.Avoid high voltage. Ensure proper wiring and some thunder protection measures.
