Wind Speed

Make | Autohelm |
Model | ST50 wind |
Web |
Connects to wind sensor on mast
Seatalk to NMEA converter then PCs
The above devices are interfaced with two personal computers.
The following marine standard networks are used:
1) Robnet
2) Seatalk
3) NMEA
Their outputs are converted into NMEA format and fed in two Noland NMEA multiplexers each which feeds one of two PCs. This is how each PC gets the same data from all devices.
The two PCs are networked at 100Mb/s
PCs and software are detailed below.
