NOTE:

If the video server used does not provide relay outputs for

Tilt control, the KC-DAR will remain in a level fixed position.

Upward angle adjustment can be made at the time of installation.

If the video server supports RS232 for PTZ, an RS232 networkable

Relay controller can be added for this function.

WIRING CONNECTIONS:

1.KC-DAR connects to KC-IFA on 1A1/1A2 terminals with 18AWG non-shielded wire.

2.Power supply (PS-2420UL) connects to KC-IFA on +/- terminals.

3.Composite video output from KC-IFA is from the BNC connector.

4.When call button on KC-DAR is pressed NO, COM, NC terminals are activated. Use proper contact (NO or NC) to connect to sensor input on video server. This will signal that the video door station has been activated.

5.OUT/GND terminals are the audio output from the video door station and connect to the audio input on the video server.

6.IN/GND terminals are the audio input from the video server to the video door station. Connect to audio output of video server.

7.UP/DN/GND terminals are for adjusting the “tilt” function of the video door station. By providing a short or relay closure to UP/GND, the camera will move up (for the duration of the closure or until it reaches the top). A short of relay closure to DN/GND will move the camera down, or to the level position.
