VB41x4 Modular Card

The VB41x4 Modular Cards are designed for use with the Modular

Rack System. The RK400 Card Cage is a powered card cage that ac-

cepts the VB41x4 cards as well as the rest of NITEK active receiver units.

This modular “plug-in” feature allows the system to be custom configured

for each application and provides easy expendability. This modular card

configuration allows for high density application, with up to 40 videos in

each modular rack.

The VB41x4 has four standard balun units on one card.

The video

balun is a passive device, requiring no power, for the transmission of standard

baseband video signals over ordinary telephone lines.

The VB41x4 is also

compatible with all of the up the coax control systems. A basic sys-

tem would use one video balun unit at each end of a twisted pair of

wires. The VB41x4 is intended for use over existing in house tele-

phone wiring, category 5 wiring or other twisted pair cable runs to pro-

vide a convenient, cost-effective alternative to coax. The VB41x4 is

designed to provide immunity from noise and interference even when

running next to line power!
