Stowe's junction box multiplexes data from its NMEA0183 input with data from its internal converters (wind, depth
, and temperature) and its combined output is present on the Dataline bus.
The Stowe Dataline bus is NMEA0183 compliant. Just add a return wire for keypad functions and general lighting
But I'm sorry to tell you that Stowe uses a deprecated wind
sentence (VWR), that is, the system will not understand another manufacturer's wind
data (MWV) directly. Some gateways still perform that conversion.
