Power Input
The DTT-Pro operates from a multi voltage input 7.5V to 24VDC 65 mA or 24 VAC 100 mA . The power
input connector is a standard 2.1mm x 5.5mm DC Coax power jack, must have positive (+) on the
center and negative (- or ground) on the outer shell. The unit is reverse protected for correct polarity and
is indicated by the Green Power LED being lit on the front panel.
Video
The video input and output are located on the rear of the unit. (see Figure 2). The video input connects
Input/Output
to the video source via the left BNC connector. The video output connects to a display, recording device,
switcher, or other equipment via the right BNC connector. Both the input and output are 1 V P-P into 75
ohms unbalanced EIA standard RS-170A / NTSC or CIR / PAL video format. Improper input termination
or looping will cause the video level to be too low and effect the text insertion. The video output is 1VP-
P whether terminated with 75 ohm or not and can drive two 75 ohm terminated loads without degrada-
tion. Additional output load will cause the level to decrease proportionally.
