W wolnej chwili próbowałem znaleźć bardziej szczegółowe informacje o serii Nasa Clipper i nie widzę nigdzie informacji, że owe urządzenia wysyłają sentencje NMEA...
W instrukcji też nie ma słowa na ten temat

Supply voltage Nominal 12v DC
Consumption, 50mA+ (25mA for display illumination max)
NMEA 0183 output sentence MWV

Hi Kris,

You can connect several devices to a single NMEA output.

Note the Duet does not have an output, Compass okay NMEA 0183 sentence HDG.

NMEA Outputs The MiniPlex has two NMEA outputs called Out1 and Out2. Each output is capable of driving up to four NMEA inputs.
