Raymarine AIS 350 Installation Instructions Manual page 60

Important:
• As detailed in the table above, the 38400 high baud rate NMEA
0183 input and output connections on the AIS unit are NOT
linked. This means that the AIS unit cannot receive NMEA
0183 data on the 38400 high baud rate input and then feed it to
the 38400 high baud rate output.
• To avoid potential data conflicts:
– Do NOT use the AIS unit's NMEA 0183 and USB connections
at the same time.
– Do NOT connect a SeaTalk
unit's NMEA 0183 and SeaTalk
time.
– Do NOT connect a SeaTalk
NMEA 0183 and SeaTalk
– If you have an AIS-capable VHF radio connected to the
AIS unit, you must disable the AIS functions on the VHF
radio. For more information on how to do this, refer to the
documentation that accompanies your VHF radio.
• *NMEA 2000 connections require the use of suitable adapter
cables.
Connecting SeaTalk
The SeaTalk ng connector enables you to connect the AIS unit to a
SeaTalk ng system.
Before connecting via SeaTalk
guidelines provided in the SeaTalk

NMEA 0183 connections
Your AIS unit can provide GPS and / or AIS data to external devices
via NMEA 0183 connections. These connections are made via the
AIS unit's power / data cable.
Typically NMEA 0183 connections are used to connect the AIS unit
to a VHF radio and / or multifunction display. Refer to the Typical
systems section for system examples.
The AIS unit features a type of multiplexer NMEA 0183 bus which
enables you to feed GPS data into the unit via NMEA 0183 and then
feed both GPS and AIS data out of the unit via the NMEA 0183
outputs. This is useful in systems where only one NMEA 0183
input exists on your external equipment, eliminating the need for a
separate multiplexer. However, only certain combinations of low and
high speed NMEA 0183 inputs and outputs are supported for GPS
system will and / or AIS data exchange. Refer to the
for a list of the possible combinations.
The NMEA 0183 connections on the power and data cable are as
