4.3 Connections
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 5.17 Advanced Mode: Video Input, page 46).
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.
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.
