Chapter 1. Introduction
UT-4500
Series Up
Converter
1.1 OVERVIEW
This manual provides instructions on the installation, operation and maintenance of the
UT-4500 Series Up Converters manufactured by Comtech EF Data Corp. Individual
specifications for each model are included in this section.
1.2 FUNCTIONAL DESCRIPTION
The UT-4500 Series Up Converters are designed for use in communication systems, or in
satellite up-link data systems, for the transmission of SCPC, DAMA and TDMA
communication signals. The Up Converters can also be used in communications system
applications with full transponder HDTV and analog TV.
The converter is designed to be hard mounted in a standard 19-inch rack or cabinet, or to
be rack mounted using slide mechanisms provided with the converter to allow it to be
serviced without its removal from the rack. An internally mounted exhaust fan for
cooling is mounted on the rear of the chassis. An AC power connector, with an on/off
switch, is also located on the rear on the chassis. A six-foot AC power cord is supplied
with the converter.

All operator controls, indicators and displays for local and remote operation are located
on the front panel of the converter. Connectors for the external interface connections are
located on the rear of the converter chassis.
