Replace ST60 Tridata with i50 Tridata

[sailjumanji]

Ok, I cabled the i50 Tridata to the white connector on the Seatalk to Seatalkng converter. (The daisy-chained ST60+ Wind and Smartpilot are cabled to the other white connector on the converter. And the converter is connected via a backbone cable to the NMEA2000 network.) I can get the depth data onto the NMEA2000 network, and as well can repeat on my chartplotter (also on NMEA2000 network).

When I go into depth calibration mode for the i50 Tridata, it allows me to set "feet or meters", and then the offset, but then immediately back to feet/meters. There is no choice to enable the alarm - it skips that step. So first question is what can I do to enable using the shallow water depth alarm?

Second question - hooked up this way, will the ST60+ wind be able to get the boat speed data so that true wind can be displayed? The i50 Tridata boat speed coming into the converter as Seatalkng data would then have to flow to ST60+ Wind as Seatalk data?
