Nitek EX1120RR Single Channel
Video Link Receiver Card Selectable 1000ft. to 12000ft
|
|
|
|
Description:
The EX1120RR is a
single channel unshielded twisted pair (UTP), long range
transmission system designed for use with the Modular Rack System.
The Modular Rack System holds up to ten (10) modular cards, in any
combination, using the Modular Card Cage (not included). Cards may
be inserted in various combinations of video and data cards. This
plug-in feature allows the system to be custom configured for each
application and provides ability for future expansion.
The EX1120RR is a
complete system comprised of a TR1120RR Modular Receiver and a
TT1120 Standard Transmitter unit. The system is designed for
operation over category unshielded twisted pair cabling. It can also
adapt to existing communication, computer network spare pairs or new
cable installations. A highly balanced transmitter output assures
that the system will not interfere with other network equipment.
Advanced receiver and transmitter electronics provide optimum video
quality and complete immunity from ground loop, hum and noise. Both
the transmitter and receiver units provide adjustments for gain and
frequency compensation, allowing each system to be “finetuned” to
the cable. These unique adjustments provide optimum performance over
the entire operation of the system. |

Features:
- Active electronics compensate for frequency and
level losses over the length of the cable
- High resolution color or monochrome video
communication signal
- High common mode rejection and noise immunity
- Built-in protection from power surges and transients,
static and electrical interferenc
- Video can share the same cable with telephone,
control and data signal
- Easy to install and configure
