R1 - IF INPUT Connector
This is the 44 MHz IF input. The required level
is +30 dBmV (from TMQAM or DDC, etc).
R2 - DC INPUT Connector
This 3-pin connector (Male) accepts the
appropriate mating DC power cable. Observe
proper orientation and wiring.
R3 - RF OUTPUT Connector
This is the upconverter output.

CONNECTIONS AND CONTROLS
All connections to and from each upconverter
are made through the rear panel.
DESCRIPTION
Figure 3 shows a typical installation utilizing 4
DUC864 upconverters used with 4 TMQAM
modulators. A PS8 power supply module is
used to power all units.

RACK MOUNTING
Adequate ventilation is very important in
multichannel installations. Units should be
spaced apart by at least one panel height
wherever possible, and some air movement is
mandatory in enclosed rack cabinets. Exces-
sive heat will shorten component life and
modulator performance will be degraded
without proper cooling.
