T Channel Upconverter 5

The 550TCPT is an upgraded version of the Dracom

550TCP. The "T" Channel model includes a built-in

upconverter to extend coverage of the input section to

include channels T7 through T13. When the T channel

upconverter module, which must be factory installed, is

present, the processor may be used in either the normal

mode with input channels starting at CH2 or in the T

channel mode where the upconverter is connected

between the input of the normal tuner and the input signal.

To use the T channel mode, the included F connector

jumper cable is simply installed between the UP

CONVERTER OUTPUT and the RF INPUT and the T

channel input signal is connected to the T7 TO T14 IN

input instead of the RF INPUT. These connections are all

on the rear panel of the processor. To use the processor

for normal input channels, the jumper can be removed

and the normal input (RF INPUT) used.

When the upconverter is used, input channel T7 is

selected by choosing channel 7 on the input channel

switch, T8 is selected by setting 8, and so on through

input channel T13 which is selected by setting 13 on the

input channel switch.

The specifications for the T series of channel processors

are identical to the non T versions when used on normal

channels without the input upconverter connection. When

the upconverter is in use, the additional specifications,

listed below, will also apply for use with T channel input

channels.

These T series processors accept T channel input

signals but output coverage does not extend below

channel 2. Thus, T channels can be converted to any

other channel in the processor’s output range starting with

channel 2 and up.

NOTE: When using the T channel upconverter module

option on the 550TCPT, avoid use on input channels if an

adjacent channel is present at the input and output. For

adjacent channel operation, use the HCP1450T,

HCP1550T, or HCP2550T models, which have additional

SAW filtering.
