Im having issues with sending a route
to my st2000+ AP from ocpn and I wonder if someone could push me in the right direction.
Im using a usb till rs232
ttl adapter (attached) that has 5v, vcc, 3v3, txd,rxd and gnd.
has +,- nmea+ and nmea-. (Yeah and seatalk
which I cant use right now),
I have put a cable between txd to nmea-, rxd to nmea+ and a external 12V battery
to the +,- on the AP.
Ocpn is set to send data and the correct sentences has been filtered for output (esentially rmb). The nmea
"filter window" shows that data is going to the Serial
But the autopilot
wont go into track mode after create a point to navigate to in ocpn.
I wonder if I need to ground the rs232
somehow and in that case where? Or if there are some other connection I need to do for the rs232 to actually send data to the AP.
Any suggestions would be appreciated. This is extremely frustrating.
