NMEA Standards:
IEC61162-1 chapter 3.5.5 state that the input shall withstand 15V between ground and input. The reference speed
specified is set at 4800 bit/s.
IEC61162-2 chapter 3.1 state that there are 3 wires to be used. (A, B and C). The reference speed for this interface is
set as 38400 bit/s.
