Applications
The video distributor TVDA-408 is used in video sur-
veillance systems. It is able to distribute the video sig-
nals of up to four video sources (e. g. cameras) to up
to eight units (e. g. monitors, video recorders, video
splitters). The 4 video inputs can be assigned to the
8 video outputs as desired (see example for applica-
tion in fig. 2).
4
Operation
Switch off the TVDA-408 prior to making or changing
any connections to other units.
1) Connect the video outputs of the video sources
(e. g. surveillance cameras) to the inputs “INPUT”
(3). Up to 4 video sources can be connected.
Connect the outputs “OUTPUT” (4) each to the
video inputs of the following units (e. g. monitors,
video recorders). Up to 8 units can be connected.
2) Use the DIP switches (5) to select the video source
for each connected video output: Set the switch “1”,
“2”, “3”, or “4” for the corresponding video input to
the upper position “ON”, set the other three
switches to “OFF”.
3) Connect the plug of the mains cable (1) to a mains
socket (230 V~/50 Hz).
4) Switch on the unit with the power switch on the front
panel. With the unit switched on, the LED next to
the switch will light up.
WARNING
The unit uses dangerous mains voltage
(230 V~). Leave servicing to skilled per-
sonnel only. Never make any modifica-
tion on the unit and do not insert any-
thing into the air vents; otherwise you
will risk an electric shock!
If the unit is to be put out of operation defini-
tively, take it to a local recycling plant for a
disposal which is not harmful to the environ-
ment.
