[CA] Integration AIS650 in existing NMEA0183 system
Hello,

I bought a used Sailing boat. Now my subject is to connect a brand new AIS650 to an existing system which is made as follows:

1. MFD C120classic + Radar
2. IS15 (Simrad)
3. AP11 Autopilot (Simrad)
4. RS35 VHF (Simrad)

Actual the “bridge” C120 to the rest of the system is made by a connection between C120 NMEA-Port and the second NMEA-Port of the AP11 (in both directions) to send the fast HDG to MFD. Parallel to this connection the output Tx of C120 is connected to input Rx of IS15.

The VHF is actually a separate “island”, gets a GPS-Signal by an own source.
I just bought a Multiplexer ACTISENSE NDC-4 to get an integrated system.

Reading the manual AIS650 I´m not sure about the characteristics of the internal MUX, means which NMEA-sentences are able to cross the AIS650 from 4.800-port to 38.400-port in both directions.

Questions:

1. Could somebody provide me with a list, which NMEA-sentences are able to
cross the AIS650 from 4.800-port to 38.400-port in both directions
2. Maybe you can recommend a configuration for my system including VHF to get
full functionality.

Thx in advance.

Welcome to the Raymarine Forum Axel,

Please click here to view a FAQ addressing this subject. Should you additionally require that the MFD receive NMEA 0183 DSC position report messages received by the VHF radio, then it would be necessary to install a 4800 BAUD NMEA 0183 multiplexer between the AIS650's 4800 BAUD NMEA 0183 IN leads and the two 4800 BAUD NMEA 0183 talkers (i.e. the NMEA 0183 output of the autopilot and the NMEA 0183 output of the VHF radio).
