Satellite Uplink Power Control Unit
WORK Microwave’s remote control unit is perfect for
use with outdoor converter units. Via the front panel,
operators can manually control the configuration of an
outdoor converter similar way to what is possible for
indoor converter units.
Versions that enable the operator to control more than
one converter from the same unit are available
(Options Dual and Multi).
Remote control of the complete setup via RS232,
RS485, or IP over Ethernet is possible utilizing this
control unit. In addition, alarm relay outputs are
provided. For connection to the outdoor unit or to the
remote controlled unit in general, an RS485
connection is used.
Uplink power control
Uplink power control is a hardware and software
option for the Remote Control Unit.
This feature senses a DC signal from a beacon
receiver. If due to additional atmospheric attenuation
caused by rain, snow, clouds, fog, or an antenna
misalignment the beacon signal is attenuated, the
transmitted signal is increased proportionally until a
configurable maximum additional gain is reached or
the maximum gain of the upconverter is reached.

Sampling and update period in seconds

Ratio between decrease of beacon signal and
increase of transmission signal (due to difference
of rain attenuation effect for different frequencies)

Clear sky value of DC beacon receiver signal

Sustain period in seconds (up 3600 seconds) for
which the uplink power control keeps the last gain
increase value (in case of deep fade conditions
where the beacon receiver can lose lock for some
period of time).
The following specifications can be monitored:

DC signal from beacon receiver

Calculated attenuation of beacon signal

Current gain increase of transmission signal
As LNAs or LNBs may show gain variation over
temperature, which would mislead the uplink power
control algorithm, there is an optional input for a
temperature sensor. A temperature sensor can be
mounted close to these LNAs or LNBs. The
characteristic for the temperature compensation can
be configured (only on Standard Remote Controller).
The uplink power control uses a DC signal from a
beacon receiver and also provides an input for a lock
signal or alarm signal from a beacon receiver.
The following parameters can be configured:

Uplink power control on/off

Maximum gain increase in reference to clear sky
gain
