The EX1120 is a complete twisted pair video system
made up of a TR1120 receiver unit and a TT1120
transmitter unit. The system is designed to operate
over Category wire or twisted pair communication
cable. It works well over existing communication
cables or computer network spare pairs. 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 provide adjustment for gain
and frequency compensation allowing the system to
be “fine-tuned” for the cable. These unique
adjustments provide optimum performance over the
entire operating range of the system and allow cable
lengths to be estimated with a wide safety margin.
The receiver and transmitter units each require 24
VAC power. In multiple receiver and/or transmitter
applications a common supply can be used for the
system.

We recommend using unshielded twisted pair wiring. The
systems will operate over wire 26 to 18 AWG but are
optimized for 24 AWG. Category cables may be used.
Individually shielded pairs should be avoided, as they
drastically reduce the operating range of the systems. Multipair cable 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 T-taps and any resistive, capacitive or inductive
devices MUST BE removed from the pair.
