Raymarine wind instrument ST60 gives wrong direction by 90 degrees

[johnalison]

I did this a couple of days ago as I fitted a new transducer and it was off by 15 degrees or so. The instructions on calibrating in the manual are just as you say here and it worked fine. I tacked back and forth and adjusted it bit by bit until it showed the same angle off the wind on each tack.

That doesn't answer his question, which is why the correct angle isn't displayed by a repeater. I had no trouble re-aligning my replacement transducer recently but I haven't checked at the Graphic Repeater because it isn't a function I use much, though when I do I am more interested in the speed and direction graphs rather than the actual bearing. I'll have a look next time I go down.

Exactly.
The windvane is showing according but not the information in the bus.

This pictures were took at same moment.

This was working good af few days before.
But when it was checking the calibration parameters in the ST50, at one moment the windvane suddenly moved to the "opposite side", like if it's switch from 30° starboard to 30° port.
But there is not calibration to change that.
The only parameters, in the equipment are:

L: Lamps
U: unit
C: windvane alignment
S: dealer mode
H/J: wind/speed damp

So I'm not able to go the previous setting. I've tried disconnecting the multiplexer (that joins NMEA2k to SeaTalk), but as mentioned, in the SeaTalk Repeater keeps showing incorrect angle.
