The RS-422 protocol utilizes pairs designated as TX+ / TX- (Talker) and RX+ / RX- (Listener). If TX+ is accidentally wired to RX-, communication fails entirely. Always isolate data loops and test polarity with a multimeter.

While not a full networking protocol like NMEA 2000, v4.11 provides clear guidelines for connecting multiple talkers and listeners using buffered splitters and isolated inputs—reducing ground loops and data collisions.

A typical sentence looks like this: $GPGGA,123519,4807.038,N,01131.000,E,1,08,0.9,545.4,M,46.9,M,,*47 The RS-422 protocol utilizes pairs designated as TX+

Single-talker, multi-listener unidirectional serial communication.

The standard speed is 4,800 baud. For high-bandwidth applications, such as Automatic Identification Systems (AIS), a high-speed variant known as NMEA 0183-HS operates at 38,400 baud. Data Bits: 8 data bits. Stop Bits: 1 stop bit. Parity: None. Standards - NMEA 0183 - National Marine Electronics
