4.3 Connections
4.3.1 Cameras
You can connect two video sources to the VideoJet X20. Any cameras and other video sources
that produce a standard PAL or NTSC signal are suitable.
1. Connect the cameras or other video sources to the BNC sockets Video In 1 and Video In
2 using a video cable (75 Ohm, BNC plug) .
2. If the video signal is not looped through, termination is performed by a software setting if
necessary (see Section 5.13 Video Input, page 43).
4.3.2 Audio Connections
The VideoJet X20 has two audio ports for audio line signals.
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
following specifications should be complied with in all cases.
The stereo plugs must be connected as follows:
1. Connect two audio sources with line level to the Audio In socket of the VideoJet X20
with a 3.5 mm stereo plug.
2. Connect a unit with line-in connection to the Audio Out socket of the VideoJet X20 with a
3.5 mm stereo plug.
4.3.3 Network
You can connect the VideoJet X20 to a 10/100 Base-T network using a standard UTP
category 5 cable with RJ45 plugs. The second Ethernet interface can be used to create a
redundant connection to the network.
1. Connect the VideoJet X20 to the network via the ETH 1 socket.
2. Connect the VideoJet X20 to a redundant switch or hub on the same network via the
ETH 2 socket.
