Sea Tel 9711-56 IMA Quick Start Operation
14-1
EAR Controlled - ECCN EAR99
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 below).
