Switching Satellites Using the ADCU
If you’re unable to switch between satellites using the IRD
remote control, use the ADCU front panel buttons to select
between Satellite A and Satellite B. Press the left button to select
Satellite A and the right button to select Satellite B.
2.4 Watching Television
TracVision G6 is designed to operate as efficiently and as reliably
as possible both when your vessel is in motion and at rest.
Cable Unwrap
The antenna can rotate a full 720° before reaching the end of its
cable. If it does so, the system automatically unwraps the cable
by quickly rotating the dish in the opposite direction. During this
time, your television transmission will freeze momentarily while
the cable unwraps and the antenna reacquires the satellite.
Conical Scan Tracking
The antenna uses conical scanning to maintain peak signal
strength to the receiver and to update the satellite’s position.
When conical scan tracking is active, the antenna moves
continually in a circular motion to sweep across the satellite’s
peak signal. The signal strength is then fed back to the control
circuits to keep pointed in the direction of the strongest signal.
If the satellite signal is lost while the system is in conical scan
track mode, the control software imposes a 45-second time-out
delay. If the signal is not regained during that time, the antenna
will search for the satellite signal. This is an automatic process
that does not require user intervention.
