Installation
6.2
Connecting the video inputs
Connect video inputs to the BNC sockets that are labelled
Video Input 1 Vss / 75
Ohm
.
Video sources that are compatible with the SIMATRIX NEO V2 provide a
PAL/CCIR video signal at a voltage of 1V
SS
and an input impedance of
75
.
Up to 16 video sources can be connected to the BNC sockets per input unit.
Each video input teminates in a 75
feed-through jumper. The plug-in jumpers are
located on the PCB next to the appropriate BNC socket.
Video signal requirements
To ensure problem-free synchronisation and correct text overlay at the video
output, the incoming video signal must have a standard level of 1.0 Vpp at 75
Ω
,
split as follows: 700 mV = signal level, 300 mV = sync level.
The incoming video signal must at least satisfy the following requirements:
The amplitude of the synchronisation pulse at each video input must be 0.3 V.
The peak amplitude of the video signal at each video input must not exceed 1.0 V
SS
.
In the case of colour cameras, the burst level at the video input must not exceed 300 mV.
If the video pulse level is too low, a cable equaliser must be wired in at the video source. This device
must then be set to boost the signal to the levels specified above.
6.3
Connecting the video outputs
Connect monitors, image recording devices or grabber cards to the BNC sockets
that are labelled
Video Output 1 Vss / 75 Ohm
.
If the signal leads are too long, a cable equaliser must be wired in at the monitor.
6.4
Mains connection
Caution
If the outer casing of the video matrix device shows signs of damage,
do not
proceed with electrical connection!
If the local electricity supply lies between 115 and 230 VAC (+10% / -15%) at a
frequency of between 50 Hz and 60 Hz, the video matrix can be connected to
the mains by plugging the mains connection cable into a wall socket in the
supply network. Plug the mains connection cable into the video matrix first. The
wall socket must be installed in an easily accessible place close to the
SIMATRIX NEO.
