2.9 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 can
’ t return any data to the unit. To enable the operation, connect the PTZ device
to the RS485(A,B) input on the DVR. 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.
2. Connect the other end of the cable to the proper pins in the connector on the camera.
3. Follow the instructions for configuring a camera to enable each PTZ device on the DVR.
2.10 Other Interfaces
There are still other interfaces on the DVR, such as USB ports. You can refer to the
