3.2.2 NMEA Mode (Mode 2)
This mode should be selected if the Mega instrument is to be
used as an NMEA data repeater with no IS12 master units. In
this mode, the Mega will display the following data -
- NMEA0183 instrument data
- NMEA0183 navigational data
In this mode only the NMEA terminals are used to link the
Mega to any master units - the network ports are only used to
supply power to the display. No data is received or transmitted
to any IS12 units connected to the Mega via the network ports.
The NMEA Out terminals will retransmit the following data -
- NMEA0183 instrument data
- NMEA0183 navigational data
