INTRODUCTION

The DTT-Pro single-channel Date-T ime-Titler overlays date, time and camera identification onto a video image,
identifying precisely when and where an event has taken place. The output signal may be displayed on a monitor,
recorded on a VCR/DVR, or printed on a video printer. The characters have full programmability in 8 gray scales along
with background in 8 gray scales. In the event the video input fails or not used the DTT-Pro will output a composite video
image with the T/D T itle information visible. Full 7.5-24V DC or AC Operation. Power input full protected from surge and
lightning with screw terminal earth ground.

The DTT-Pro uses a precision crystal-controlled clock for unparalleled +/-5 ppm accuracy. Compatible with
both color and monochrome cameras NTSC/EIA or PAL/CCIR formats, its compact size and low power consumption
make it perfect for portable and covert applications. Fully programmable for all US and European Time/Date formats for
world compliance.

5

The DTT-Pro operates from a multi voltage input 7.5V to 24VDC 65 mA or 24 V AC 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.

CONNECTIONS

Video
Input/Output

The video input and output are located on the rear of the unit. (see Figure 2). The video input connects
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 st andard RS-170A / NTSC or CIR / P AL 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 1VP­P whether terminated with 75 ohm or not and can drive two 75 ohm terminated loads without degrada­tion. Additional output load will cause the level to decrease proportionally.
