Data bridging
NMEA 0183 to NMEA 2000
All supported NMEA 0183 sentences entering the system are internally bridged (converted) to
NMEA 2000, and output via the NMEA 2000 port for any other devices to use. The only excep-
tion is AIS data.
NMEA 2000 to NMEA 0183
The NMEA 0183 sentences shown in the ‘Transmit’ rows of the NMEA 0183 Supported Sen-
tences table will be generated if the data is available from a NMEA 2000 data source.
Ethernet to NMEA 2000
Limited data is bridged from the Ethernet echosounder: Speed, depth and temperature are
bridged to NMEA 2000 and NMEA 0183.
Multiple Displays
In multi display setups, each display can be used to convert data from a different NMEA 0183
talker, and will be available to any device on NMEA 2000. Each display can be setup for output-
ting different NMEA 0183 sentences.

Note:
When bridging data from ethernet, an NSS display has to be nominated to bridge
the data. If this nominated display is turned off, no data will be displayed, until the display is
turned on or another display is selected to bridge the data.

Note:
NMEA 0183 to NMEA 2000 bridging only applies to the NMEA 0183 sentences outlined
in the “NMEA 0183 supported sentences” on page 61.

Note:
For high speed heading data input in to a radar for MARPA functionality, conversion
should be done via an AT10HD.
