NMEA Guide

For the technically inclined I found this guide to NMEA 183 while trying to sort out connecting Coastal Explorer to an S1000 RayMarine Autopilot. It was the first place where I found a reference to NMEA common on transmit and receive as being the same as signal ground on RS232.

I think there is one mistake in a drawing where NMEA IN DATA and NMEA IN Common are reversed.

Thanks,

Good basic information. Too often, the manuals don't explain the steps or define the terms.
