Technote 4: Setting up TO-559 Stereo Transmodulators
The equipment converts DVB-T digital TV programs into terrestrial band, analogue TV
channels. Stereo Trans-modulators comprise SAW filtering for maximum harmonic reduction
and true VSB response for adjacent channel operation.
IMPORTANT:
Layout of the modules must be as shown above. Power Supply (FA-310/312)
must be located on the far left hand side and launch amplifier (PA-720) must be the next
module in the chain. Please look at the above picture.

PROGRAMMING
Programming of Modules
Ensure the following prior to programming:
•
It is necessary to connect all the modules to the support frame SP-226 (code 9120130)
for the system to function.
•
It is also recommended that you make the earth connection to the building using a cable
with a section of at least 4 mm.
•
Ensure that you have the Alcad programmer PS-003 with
firmware version 4.7
or later.
•
Power supply/Control cable must be plugged into each module.
DO NOT ADD OR
REMOVE
modules without disconnecting mains supply power from wall outlet. Always
disconnect the equipment, and then reconnect it to the mains supply so that the
amplifier recognises the new module. Failure to do so can cause equipment to fail.
