ST60 tridata not sending data

[SVNeko]

Hi Chuck, yes, the system is part Seatalk and part Seatalk NG. The heading data comes from the Raymarine fluxgate compass integrated with the SPX30 course computer. The system has several devices to show data from the Seatalk bus - 2 e125's and an ST60 multi, ST60 maxiview and ST60 wind, along with the tridata. The speed and temp data go directly from transducer to the ST60 tridata, which is on the Seatalk bus. Temp data is also shared from the tridata with the other instruments and does appear. Speed data does not pass through the Seatalk bus, although it formerly did. All the devices capable of displaying heading, app wind dir and speed, and speed are configured to show such data, and they formerly did. Now speed and anything derived from speed does not appear. Heading does appear.
