Dear Alex2035, bdbcat and other forum members.
Thanks for you comment.
The configuration is indeed equiped with a Raystar 125 GPS wich is connected in the Seatalk system / way. See attached file.
The SPX10 Course computer is connected to a rudder
refernce unit; but on the dashboard is no rudder
The only program using the COM1 is OCPN! And the PC is only a listener via that port. I stopped trying to get the AP operating in a route
; it seems to me that first the system basicly must be oke. Therefore I also shut down the AIS
during the trial (COM2).
The NMEA sentences mentioned in the manual from the Raystar 125 as you copied Alex2035 are these also available when the connection is made in the Seatalk system? Thats not sure (not mentioned) I gues.
Back to what you metioned bdbcat about the NMEA sentences. So it's clear there is no RMC sentence coming in, and I can't (re)configure the software
of the Raystar GPS. So OCPN has to operate with the VTC sentence; and this one has no True course data, but Magnetic data.
The same is going on with the Compasscourse information. There OCPN can look at HDG, or HDM. Both sentences are available in my system. These sentences represent no True Heading, wich is (seems to mee) the only correct data for displaying the Compasscourse (Variation is not given!)
What I can try is to connect the Raystar 125 in the NMEA way as a talker to the Raymarine
interface box, instead of the Seatalk way as it is at the moment. In that case the RMC sentence must be produced I gues?!
The risk is that the SPX10 isn't correct operating anymore?!
Members I like to hear your opinion about this
