Live video transmission system for operation over
twisted pair, Category 5, 6 or 7 cables.
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 2,
3, 4, 5, 6 or 7 twisted pair cable. It works well over 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 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 power supply can be used for the
system.

- Active electronics compensate for frequency and
level loss
providing the highest quality video
- High resolution color or monochrome video
- Immunity to ground loop. Video and AC can be run in a
common raceway,
where code allows
- Built-in protection from power surges, transients static or other electrical interference
- Video can be run in the same cable with telephone
and computer signals
- Weather resistant design
- Easy to install

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 2, 3, 4, 5, 6 or 7 cable 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 co-existent 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.
