I'm trying to output nmea
RMC to a DSC vhf radio
, using opencpn's multiplexing but the output seems to be corrupted - see attached screen
shoot. In the settings, there is only checked for "forward RMC" - nothing else"
is connected to a 4 port serial
to ip nmea
converter (transas) and runs at 115200, the plotter with opencpn
4.4 gets the nmea feed from the gps
over tcp 10.8.1.10:50000 and works as expected. also the system gets AIS
input form a serial ais
at 38400 connected to converter and feeds the system with ais 10.8.1.10:50003 - works great ( turned off during trouble shooting so not seen in the debug window)
from the sentences seen in debug, I can see that the GNRMC is forwarded ( the gps is digitalyatch dualnav serial gps) The radiio is from 2004 and might have a problem with the GN prefix so tips on how to rewrite to GP rmc or only rmc would be fine.
Eveen if I disconnec the serial plug
to the radio
, the message is corrupted so it seems that the error is a internal opencpn
