Hello everyone.
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.
The
autopilot 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 port.
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.
