3.11 RS485
When the 10.2-inch combo 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
10.2-inch combo DVR. See

Figure 3-10.
Since RS485 is disabled by default for each camera, you must enable the PTZ settings first. This
series 10.2-inch combo DVR supports 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. Please follow the instructions to configure a camera to enable each PTZ device on the 10.2-inch
combo DVR.
