[TG] [TG11] Connecting spx/st 60 network to a st290 ST2 network

[Tom - Raymarine - Moderator]

Hello Wouter,

I have put some connection advice on your other post, but on these problems:

Quote:...completed it with a connection to the DPU. Result: seatalk failure, but power on all displays...also the st290 wind.

At least, it sounds like you have (at least) two power supplies into the system (via the ST1 network, via the dedicated power to the DPU?) which you should not have. Only ever have one network power supply for ST1/ST2/STNG/NMEA2000.
If you disconnect everything from the DPU except Seatalk yellow and shield/bare (not red), and connect power to the DPU, do you still get Seatalk Fail? If so, I think that the Seatalk comms chip in the DPU has failed. Failed Seatalk devices are known to pull down the whole network and cause these alarms.

Quote:Then, i connected the DPU to the st290 data display, the windpod, st60cable and windmeter. Result: no winddata on the displays.

What does your ST2 network look like in detail? ST2 is an NMEA2000-like CANbus network and must always have 2x backbone terminators. I don't see any in your drawing: are they fitted? If not, the network won't work. I would suggest reading the ST290 Installation manual, if you want to start working with this old system. Please be aware that ST290 dates from 2002 and was retired over 10 years ago.

Regards,
Tom
