The series DVR also support NKB operation. You can operate the DVR from the keyboard controls

instead of using the control pad on the front panel of the unit.

2. Connect the KBD keyboard into one of the RS232 ports on the DVR or through network.

3.10 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. See

X289H289H289HFigure 3-8X.

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. Please follow the instructions to configure a camera to enable each PTZ device on the DVR.

3.11 Other Interfaces

There are still other interfaces on the DVR, such as USB ports. You can refer to the Figure 3-18 for

more information.
