4.2 Connections
Monitors
As required, you can connect an analog video monitor (PAL/NTSC) or a VGA-compatible
computer monitor.
X Connect an analog video monitor to the BNC Video Out socket using a video cable
(75 Ohm, BNC plug) or
X connect a VGA-compatible computer monitor to the VGA sub-D socket using a video
cable (VGA,
15-pin sub-D plug).
Audio Connections (Audio Version Only)
The audio version of the VIP XD has two audio ports for audio line signals as well as a
microphone input and a loudspeaker output.
The audio signals are transmitted two-way and in sync with the video signals. As a result, you
can connect a speaker or door intercom system at the destination point, for example.
The stereo plugs must be connected as follows:
1. Connect an audio source with line level to the Line In socket of the VIP XD with a 3.5 mm
stereo plug.
2. Connect a unit with line-in connection to the Line Out socket of the VIP XD with a 3.5 mm
stereo plug.
If you wish to connect a microphone and a loudspeaker directly:
1. Connect the microphone cords to the MIC and GND connections on the push-in terminal.
2. Connect the loudspeaker cords to the SPK connections on the push-in terminal.

intercom systems. The following specifications should be complied with in all cases.
