I stand corrected, Fred.
When the Garmin rep had me change the setting for the NEMA port 2 from NEMA to AIS Input, I thought it was due to the baud rate. Now I'm guessing it is about the format of the data being received. And I also thought there was some significance to the fact that the AIS is only connected to one of the wires on the 541's second NEMA183 port.

The radio already has the GPS built into it, and does not use a separate GPS input. The connection from the AIS to the 50s will only be the AIS output information from the radio. That information is transmitted over a single wire, which gets connected to one of the wires in the 2nd NEMA 183 port on the plotter. The output from the AIS is at something like 18,600 Baud - which is way higher than 183, and I think higher than NEMA2000. The port on the 50s will get configured for the AIS information by a selection in the setup menu for the plotter. You won't need to make either a NEMA 183 or a NEMA 2000 connection. Rick
