Does anyone know of problems using the Plugable USB to RS-232 DB9 serial
adapter (Prolific PL2303HX chipset) under Windows 7 for Autopilot
I have it installed with the latest drivers on COM5. The port is set to 4800 baud under device manager. I can access COM5 fine using Hyperterm and do a loop back test. I can also see data received in Hyperterm if I test COM5 by connecting to my Raymarine
course computer NMEA
The log file shows that Opencpn
(Iím running V2.5) recognises the port when I set Autopilot
output to COM5. I have separate COM ports
on COM3 (radargadget) and GPS
on COM4 (Transystem GM-2). I have set the .ini file to send RMC as well as RMB. I set a Waypoint ďGotoĒ (although the boat is at the dock) so that there is some navigation
data active, but there appears to be no data being sent. Iím using two wires Ė pin 5 for NMEA- and pin 3 for NMEA+. Iíve even tried pin 2 in case I got the receive/transmit round the wrong way.
What am I doing wrong? Is there any way of logging activity, i.e. what Opencpn
thinks it is sending? Any problems I should be aware of?
