NMEA/DGPS Wiring
To exchange NMEA or DGPS data, the unit has two NMEA 0183 version
2.0 communication port. Com port one (Com-1) can be used to receive
NMEA format GPS data or DGPS data. Com-1 can also transmit NMEA
format GPS data to another device. Com-2 is for NMEA output only.
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-2 uses the blue wire for transmit.
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
