[TG] [TG11] ECI-100 & STW

[Tom - Raymarine - Moderator]

Hello BernieK,

The ECI100 should pass STW data in PGN 128259 from engine-side NMEA2000 to STNG, so if that's not coming through that suggests that perhaps it's not present (in the standard PGN at least) on the engine side.
It ought to be possible to tell though by temporarily bypassing the STNG network and ECI100 and connecting the Axiom Pro's NMEA2000 connector directly on to the end of the Devicenet cable that is currently going to the engine side of the ECI100, then checking/recording the NMEA2000 data there. That will show what is and is not present on the engine side of the ECI.
If you connect like this and go to Home > Settings > Network > Diagnostics > NMEA Devices and Messages > NMEA Messages and see what PGNs are being listed - do you see 128259? If in doubt, record some of the data and post it back here and we'll see what is and is not present.

If standard NMEA2000 STW is not present (or is, but is not being bridged by the ECI100 for some reason) then yes, we do offer NMEA2000 STW sensors - see 'i70 Smart Transducers' at https://www.raymarine.com.au/view/index-id=1479.html for details - or http://analogue transducers connected via an ITC-5 interface. I would generally recommend the analogue+ITC5 route rather than an NMEA2000 transducer: they're a similar price but more modular, and (unlike the NMEA2000 types at present) can be calibrated through an LH3 MFD without requiring a dedicated instrument display.
Hopefully this won't be required though.

Regards,
Tom
