PC-DI4 NMEA/Serial cable with power converter.
The PC-DI4 is similar to the previous accessory, but the serial cable
portion has bare wires instead of the DB-9 plug. This allows you to
make a NMEA or serial connection with a device that doesn't use a DB-
9 plug. See the following diagrams for general wiring connections. Read
your other product’s owner’s manual for more wiring information.
NMEA/DGPS Wiring
To exchange NMEA or DGPS data, the unit has one NMEA 0183 version
2.0 compatible 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.
In the PC-DI4 cable, the wires for the com port are combined with the
power wires to form the power/data cable. Com-1 uses the yellow wire
to receive, the orange wire to transmit and the black shield wire for
signal ground.
