4.3.1Cameras

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).

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.

× Line In:

Impedance 9 kOhm typ., 5.5 Vp-pmax. input voltage

 

1

× Line Out:

Impedance 10 kOhm typ., 3.0 Vp-pmax. output voltage,

 

 

 

impedance 16 Ohm min., 1.7 Vp-pmax. output voltage

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.

NOTICE!

 

You cannot create a connection to a second 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.
