Nmea 0183/DGPS Cable Connections | Lowrance electronic LMS-480DF

An optional 8-foot, CA-4 external power cable with a cigarette lighter adapter is available from Lowrance.

NMEA 0183/DGPS Cable Connections

NMEA is a standard communications format for marine electronic equipment. For example, an autopilot can connect to the NMEA inter- face on the LMS-480 and receive positioning information. The LMS-480 can exchange information with any device that transmits or receives NMEA 0183 data.

DGPS is an acronym for the Differential Global Positioning System. DGPS supplements and boosts the accuracy of basic GPS. DGPS was developed by the U.S. Coast Guard, which is responsible for the sys- tem's operation in the United States. Since it's creation, DGPS has be- come the international maritime standard for marine navigation.

The most popular DGPS system relies on a grid of ground-based trans- mitters that send correction signals to DGPS receivers. These in turn, connect to the GPS receiver (such as the LMS-480). Lowrance offers an optional DGPS receiver for your unit.

See the following diagram for general wiring connections. Read your other product’s owner’s manual for more wiring information.

NMEA/DGPS Wiring (Data cable)

To exchange NMEA 0183 or DGPS data, the LMS-480 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 four wires for the com port are combined with the Power Supply cable and NMEA-2000 Power cable to form the power/data cable (shown earlier). Com-1 uses the yellow wire to transmit, the orange wire to receive and the shield wire for signal ground. Your unit does not use the blue wire.
