DIP switches set distances for optimum color or B/W video performance by setting gain, frequency compensation and equalization. The EX1120 provides higher resolution video over the EX560 operating range and is recommended for applications under 6,000 feet where higher performance is required. System also provides high noise immunity, ground loop immunity and surge protection. The EX1120 is also recommended for Repeater applications where transmission distances in excess of 12,000 feet are required and a Repeater system can be installed in between.
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 operation 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 "finetuned"
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 24VAC power. In multiple receiver and/or transmitter
applications a common supply can be used for the
system.

Wire and Cable Recommendations
Twisted Sender is recommended for use with unshielded twisted pair (UTP) wiring. The systems will operate over wire gauges from 26AWG through 12AWG but are optimized for 24AWG. Category 2, 3, 4 or 5 cable may be used. Individually shielded pairs should be avoided, as they drastically reduce the operating range of the systems. Multi-pair cable 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 T-taps and any resistive, capacitive or inductive devices MUST BE removed from the pair.
