NMEA2000 / SimNet | NSS Installation Manual
Data bridging
NMEA 0183 to SimNet / NMEA2000:
All supported NMEA 0183 sentences entering the system are internally bridged (converted) to
SimNet / NMEA 2000, and distributed on SimNet for any other devices to use. The only excep-
tion is AIS data.
SimNet /NMEA 2000 to NMEA 0183:
Only the selected SimNet / NMEA 2000 active data sources for the NSS are used in bridging.
The NMEA 0183 sentences shown in the ‘Transmit’ rows of the NMEA0183 Supported Sen-
tences table will be generated if the data is available on SimNet / NMEA2000.
Ethernet to SimNet:
Limited data is bridged from the Ethernet echosounder: Speed,
depth and temperature are bridged to SimNet and NMEA0183.

Example of data bridging
A In this example a NMEA0183 (talker) is connected to NSS 1
B The NMEA sentences are bridged across to SimNet and distributed on the SimNet
network. Note: AIS data is not bridged
C The NMEA0183 listener connected to NSS 2 can receive the NMEA0183 sentences
from the device connected to NSS 1 and also from other devices that are on the
SimNet network, in this case heading and GPS
 Note: An NMEA0183 talker can be connected to each NSS, and both sets of data will be con-
verted to SimNet. Each display can be setup for outputting selected NMEA sentences.
 Note: Speed, temp and depth data from the echosounder transducer that is to be displayed
as an instrument has to bridge from Ethernet to SimNet. An NSS display has to be nominated
to bridge the data. If this nominated display is turned o , no data will be displayed, until the
display is turned on or another display is selected to bridge the data (see page 38)
 Note: NMEA0183 to SimNet bridging only applies to the NMEA0183 sentences outlined in the
Supported NMEA0183 sentences section of this manual (see page 64)
