NMEA 0183 device connection

The unit has a combined power and data - NMEA 0183 serial port,
providing both an input and output for NMEA 0183 data. For
connection location, refer to "Rear connections" on page 13.
The NMEA0183 sentences output can be individually turned on or
off. For a complete list of sentences, refer to "NMEA 0183 supported
sentences" on page 56.

Note:
Ú The majority of NMEA 0183 devices communicate at
4,800 baud. AIS is a common exception, and normally
transmits at 38,400 baud.
Talkers and Listeners
Do not connect multiple devices outputting data (Talkers) on to any
serial input (RX) of the unit. The RS422 protocol is not intended for
this type of connection, and data will be corrupted if more than one
device transmits simultaneously. The output (TX) however may
drive multiple receivers (Listeners). The number of receivers is finite,
and depends on the receiving hardware. Typically three devices is
possible.
