CONNECTIONS
Power
The VDA124RM12-RoHS/VDA212RM12-RoHS uses an external DC power
supply to provide power to the unit. It can also be run from a regulated
+12VDC (+/- 25%) power source. Connect the Plus side of the 12V power
to the center connection of the power connector on the rear of the VDA
unit. Connect the ground connection tot he ring of the power connector.
Video
Connect the video source (i.e. camera) to the IN connector on the VDA
unit. Connect the OUTPUT signals from the VDA unit to the video displays
or other equipment as required. Each output must only have a single 75
ohm termination. The VDA124RM12-RoHS has one set of inputs for all 24
outputs while the VDA212RM12-RoHS has two sets of inputs, each driving
a row of 12 outputs. The VDA124RM12-RoHS/VDA212RM12-RoHS uses
female BNC connectors.
LEVEL ADJUSTMENTS
Each row of outputs (12) has a level adjustment accessible via the rear
panel. For the VDA124RM12-RoHS, each adjustment affects the top or
bottom row of output connectors aligned with the adjustment. For the
VDA212RM12-RoHS, each adjustment affects it
=
s respective channel
aligned with it. Adjustments can be made via a small flat blade
screwdriver.
