Quick Start Operation 5012-91 Installation Manual
14-1
14. Quick Start Operation
If your system has been set up correctly, and if the ship has not moved since the system was used last, the system should
automatically acquire the satellite from a cold (power-up) start. Once the satellite has been acquired, the modem then should
achieve lock and you should be able to use the system.
14.1. If satellite signal is found AND network lock is achieved:
1. Tracking will take over (front panel
Tracking LED will be ON) and
automatically peak the antenna
position for highest receive signal
level from the satellite.
2. When the ICU has signal above
threshold AND modem has network
lock the antenna will continue to track
the satellite.
3. Satellite Name (if entered), Tracking
indicator, Modem Lock indicator and
signal level (number value and bar
graph) will be displayed in the header
of the MXP GUI pages.
Upon completion of the above, the system will
continue to operate automatically, indefinitely
until:
•
AC power to the system is
interrupted OR
•
The satellite signal is blocked OR
•
The ship sails into an area of
insufficient satellite signal
strength/level.
14.2. If no signal is found:
If the system does NOT automatically find the satellite from a cold start, follow the steps below:
1. The Tracking LED will flash for a short
period of time (Search Delay)
followed by the Search LED coming
ON.
2. The ICU will automatically move the
antenna in the selected Search
pattern until looking for a signal value
that is greater than the threshold
value (red bar in the bar graph).
