C.8.3 Inmarsat G5 Driver
The Inmarsat G5 driver uses two interfaces on the FURUNO ACU VSAT KU: RS-232
and LAN1.
RS-232
The RS-232 serial port outputs NMEA GPS strings that can be used by the Inmarsat G5
system to feed GPS to the VSAT modem. The baud rate is fixed at 4800 baud and the
NMEA string is GPGGA and is output every 15th seconds.
Example of a GPGGA string:
$GPGGA,065401,5500.000,N,01200.000,E,1,08,,0.0,M,,,,*32
The RS-232 serial port also supports serial commands to configure and verify the LAN1
IP settings.
The following serial commands are supported:
