This protocol, used in the nautical sector, is derived from the CAN protocol.
Is it possible to interface and display messages using one of your products?
We, using an Actisense NMEA/USB interface, can see the packets. It would be useful to be able to acquire them in the Logic Machine.
Certain LM models have on-board low-speed CAN FT which is not compatible with standard high-speed CAN. Try connecting USB interface to LM and post what you get in System config > Status > System log.
LM can communicate with the gateway but it uses a closed protocol. There some reverse-engineered implementations but I wouldn't use them in production.
Even with a direct connection to CAN network it would not work out of the box. It would required monitoring the bus to figure out the addressing and message structure.
