18.DC-Motor Driver Module for Azimuth (DDM).
19.Azimuth motor.
20.Azimuth encoder.
21.Rotary joint.
The cable signals for the ADU (DC power, internal modem
communication, TX IF, RX and L-band TX) to and from the ACU have
to be ported from the stationary platform to the azimuth rotating
part of the ADU. This is done via the rotary joint.
22.Feed horn.
The feeder horn carries the mirror centred of the dish and in the
correct distance. Thereby the signal from the satellite is reflected by
the dish and picked up by the mirror. Then it is transported through
the horn to the OMT.
Before contacting your service partner check the LEDs on all modules
(VIM, DDMs, PCM, PMM and ISM). See
Figure 8-21: Above Deck Unit modules (continued)
