3.9 RS232
You can connect the NVR with POS or Keyboard through RS232.
With POS system, the NVR can communicate through RS232 and network. For the POS system, the
NVR can integrate the text content and even search the record through the info.
The series NVR also support NKB operation. You can operate the NVR from the keyboard controls
instead of using the control pad on the front panel of the unit.
To connect a NKB keyboard to the NVR:
1. Assemble the KBD keyboard according to the instructions in its accompanying installation manual.
2. Connect the KBD keyboard into one of the RS232 ports on the NVR or through network.
3.10 RS485
When the NVR 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 NVR. See

.
Since RS485 is disabled by default for each camera, you must enable the PTZ settings first. This
series NVRs support multiple protocols such as Pelco-D, Pelco-P.
To connect PTZ devices to the NVR:
1. Connect RS485 A,B on the NVR 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 NVR.
3.11 Other Interfaces
There are still other interfaces on the NVR, such as USB ports.
