Other Interfaces
You can connect the DVR with POS or Keyboard through RS232.
With POS system, the DVR can communicate through RS232 and
network. For the POS system, the DVR can integrate the text content and
even search the record through the info.
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.
There are still other interfaces on the DVR, such as USB ports.
