[CA] [CA11] ST2000+ NMEA0183 Wifi Connectivity

[prjacobs]

I have an ST2000+ connected to my Garmin 76Cx GPS via a wire to pin 6 (NMEA +) on the autopilot, and a wire to pin 5 NMEA-)connected to ground. Using this setup it will GOTO a waypoint, performing as indicated in the ST2000+ manual.

Recently I added wifi to the boat, using a YakBAK NMEA wireless unit from http://yakbitz.com. Using OpenCPN, I've connected, via wireless, to my AIT2000 AIS transceiver and receive AIS and GPS data on my tablet. I connected the YakBAK Tx terminal to the autopilot NMEA+, and there's data flowing to the autopilot, but it's not responding to GOTO commands as it does with the Garmin GPS.

With the Garmin, after entering Auto mode and pressing +10 and -10 together, various data flows across the ST2000+ screen and pressing +10 and -10 together again puts it in track mode. But connected to wireless, entering Auto mode, and pressing +10 and -10 together the ST2000+ flashes a "Z" symbol. Pressing +10 and -10 together again simply returns it to auto mode.

I've done data captures from the YakBAK wireless to Autopilot, and also from the GPS to Autopilot, but don't have the knowledge to interpret this info. Can someone with experience in this help me out?
Thanks!
