Lowrance GlobalMap 2000 Installation And Operation Instructions Manual page 7

The wiring connections for the NMEA 0183 version 1.5 are different than
the ones used for the NMEA 0183 version 2.0. If you are using version 1.5,
then use the shielded green and red wires on the mapping unit's NMEA
cable. If you are using version 2.0, then you'll be using all four shielded
wires on the NMEA cable.
If you're using a Lowrance GPS module, simply plug its cable directly into
the in-line connector on the mapping unit's cable. This sends navigation
data directly to the mapping unit without using any NMEA input. You can,
if desired, use either NMEA output to drive another device while using the
Lowrance GPS module as an input. This mapping unit also has the
provision for a DGPS beacon receiver for use with the Lowrance GPS
module.
