Unit for Modular Twisted Pair Video System
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.

Wire and Cable Recommendations
Twisted Sender systems are recommended for use with
unshielded twisted pair (UTP) wiring. The systems will operate
over wire gauges from 26 AWG through 12 AWG but are
optimized for 24 AWG. Category cabling may be used. Individually shielded pairs should be avoided, as they drastically
reduce the operating range of the systems. Multi-pair cable
(>15 pairs) with an overall shield is acceptable. Video can be
operated in the same communication cable coexistent with
telephone, computer, control signals, power voltages and other
video signals. While video may be routed through telephone
punch down block terminals, any bridge-taps, also called Ttaps and any resistive, capacitive or inductive devices MUST BE
removed from the pair. For more specific information regarding
wire types, gauges and proper installation techniques, please
call 800-528-4343 for technical assistance. More information
is also available on the CCTV System Design Guide Sheet.
