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 PAL video 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-R44P is fairly straightforward, however, please take note of the following:

1.The V-R44P has 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-R44P uses 12VDC, 3.0amp regulated power. Be certain that these specifications are met when using a power supply other than the one supplied to you by Marshall Electronics. The center pin on the coaxial power connector for the V-R44P is the POSITIVE terminal and the outside ring is NEGATIVE. Any battery operation of the V-R44P must have this polarity configuration.

4.The Video inputs on the rear of the panel are 75 Ohm self-terminated. The loopthrough 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 PAL signals. Each screen is independently controlled allowing the user to view a PAL signal on one screen and an NTSC signal on the other.

6.The tally system on the V-R44P is 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 NOT GIVE POWER TO THE PINS. The pinout is as follows:
