Sea Tel 2400 Dual Band C/Ku Quick Start Operation
13-1
EAR Controlled - ECCN EAR99
13. 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.
13.1. I f 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.
13.2. I f 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).
3. Not finding a signal greater than
Threshold, the bar graph will stay red and
the antenna will reach the end of the
prescribed search pattern.
4. The antenna will retarget and the cycle will
repeat (Search Delay timeout, conduct
search pattern followed by retarget).
