Also on the GX2100 - GPS data is not repeated on the AIS data line - I don't know if this is rectified on the GX2150. I have a GX2100 with a GPF300i - they play very well together, but it is a pain to have to run two serial lines to the computer to get both AIS and GPS data.
Please have another look at my "Plan E" schematic. AIS data goes directly from the radio to the Bluetooth dongle at 38400. It does not go through the baud rate converter.

SH tech support confirmed that GPS data is not repeated, in compliance with the NMEA 0183 standard. That is why the Oregon GPS is tethered to the Netbook. I am considering a further revision that will add a second Bluetooth dongle to pass the 18x GPS data to the Netbook wirelessly instead. It might be a good idea to be able to monitor the GPS fix that the DSC/AIS is getting. I'd hate to hit the "distress" button and have the wrong coordinates go out.
