The V-R44Pis a rack mountable unit that offers four 4" high-resolution active matrix LCD panels. Each of the four 480

× 234 pixel screens has it's own set of controls for color, tint, contrast, and brightness. Each panel has it's own input

with loopthrough capability, a self-powered 3 color tally system and auto-recognition of NTSC or PALvideo formats.

This unit is only 2 rack spaces high, and can be tilted up to 90 degrees while rack mounted, making it the smallest video

monitoring system of its kind. Like all of the V-R Series, this unit is constructed of steel and aluminum, and comes com-

plete with power supply and owners manual.

The operation of the V-R44Pis fairly straightforward, however, please take note of the following:

1.The V-R44Phas been designed to fit in a 2U space on your rack. It is important to use 4 screws to hold the

ears to the rack. Be certain that the ears are aligned vertically, this is important to the tilt function (see

back page).

2.Each LCD Panel comes with a protective plastic film that must be removed by carefully lifting the film from

the corner and peeling it off. Be certain not to apply any pressure on the LCD panels, they are fragile and can

break. Scratched, cracked or broken LCD screens are not covered by our warranty.

3. The V-R44Puses amp regulated power. Be certain that these specifications are met when using a 12VDC, 5.0

power supply other than the one supplied to you by Marshall Electronics. The center pin on the coaxial power

connector for the V-R44Pis the POSITIVE terminal and the outside ring is NEGATIVE. Any battery operation

of the V-R44Pmust have this polarity configuration.

4.The Video inputs on the rear of the panel are 75 Ohm self-terminated. The loop through feature uses active

components and is always active as long as power is supplied to the unit.

5.Each screen has the capability to automatically detect NTSC or PALsignals. Each screen is independently

controlled allowing the user to view a PALsignal on one screen and an NTSC signal on the other.

6.The tally system on the V-R44Pis accessed via the DB-15 connector on the back of the unit. The system works

by closing the contacts between a ground pin and the corresponding LED pin. The system is self powered, DO
