NMEA/DGPS Wiring
To exchange NMEA or DGPS data, the LMS-320 has one NMEA 0183
version 2.0 communication port. Com port one (Com-1) can be used to
receive NMEA format GPS data or DGPS data. The com port can also
transmit NMEA format GPS data to another device.
The three wires for the com port are combined with the two power
wires to form the power/data cable (see the drawing on page 33). Com-1
uses the yellow wire to transmit, the orange wire to receive and the
shield wire for signal ground.
Com-1 wiring to receive DGPS position information
from a DGPS receiver.
Com-1 wiring to receive NMEA position information
from some other GPS receiver.
Com-1 wiring to transmit NMEA position information
