I am looking for some help from this excellent support community. I have installed my new Furuno gear - TZT13X, SCX20, DRS4D-NXT, HUB 101, and FIP-460. For now, I am hoping to continue with my Raymarine Smartpilot S2G computer with ST8002 display. I have interfaced the TZT13X NMEA 0183 output to the S2G 0183 input using the multi-cable. When I set a "go to" on the TZT13X, the bearing to waypoint is seen by the autopilot as a True value, not Magnetic, and the autopilot will attempt to steer to the true bearing. Actual heading information is currently coming from the Raymaring fluxgate. I have attempted to send heading information from the TZT13X instead, however there is no heading sentence (HDM, HDT) available to send from the TZT13X 0183 output. I have tried sending the RMB and RMC sentences in all combinations - RMC sends variation, neither send heading.
I'm not sure I have done a great job describing my issue. Bottom line is when I tell my autopilot to go to a waypoint, it receives all the information it needs (BTW, XTE, etc.) but the bearing to waypoint it steers to is a heading that is off by the difference between the true and magnetic headings.
I appreciate any help/insight you might have!
Thanks,
Doug
