Raymarine SPX Autopilots for example , receive RMB as well as other NMEA sentences, but it will not transmit RMB, it does output HDG and RSA (heading deviation and variation and rudder reference if one is fitted) regards. alex
Alex have you actually tried modifying the .ini file with this syntax:
NMEA Sentence Out=RMB;RMC ? I cannot get it to work, even if I remove the spaces like all of the other commands in the file. In fact when I run OpenCpn after editing the file, my alterations are removed prior to the next prog start. Has anyone had success with this? If so, what exactly did you type and where did you type it? I inserted the line after [Settings/NMEAAutoPilotPort] Ommitting the AutoPilot
made no difference.
What I am trying to do is use the NMEA from my Commar AIS
to drive my ST-7000+ autopilot. I have successfully done this via OPenCpn using a USB/RS232 converter connecting pins 3 & 5 to the ST-7000+ NMEA In (2) terminals. I also want to send the appropriate data to my DSC radio
. By doing this I do not have to also power up my Furuno
I see all data on the pilot display except SOG and COG, so I do need OpenCpn to send RMC sentences too. Why this is not the default I don't know? At the helm I want to see SOG and COG and not have to duck down to the Nav desk. If I use an autopilot out connection with Nobeltec
then I do get ALL the data, so it is not a hardware
I wonder if the syntax in the manual is correct? Any help would be much appreciated.
