ESCRIPTION
The DT-4500 Series Down Converters are designed for use in communication systems,
or in satellite downlink data systems, for the transmission of SCPC, DAMA and TDMA
communication signals. The Down 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 (48.26 cm) 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.
