To prevent electrical interference, route the power, transducer, and GPS cables away from other wiring, especially the engine’s wiring harness. VHF radio antenna cables radiate noise when transmitting, so be certain to keep the unit’s wires away from it, also.

NMEA/DGPS

NMEA is a standard communications format for marine electronic equip- ment. For example, an autopilot can connect to the NMEA interface on the LCX-15CI/15CT and receive positioning information.

DGPS is an acronym for Differential Global Positioning System. The most popular DGPS system relies on a grid of ground-based transmitters that send correction signals to DGPS receivers. These in turn, connect to the GPS receiver (such as the LCX-15CI/15CT with the LGC-12S GPS mod- ule). This gives more accurate positions than is otherwise possible.

NMEA/DGPS Wiring

The LCX-15CI/15CT has two NMEA 0183 version 2.0 ports. Com port one can be used for either NMEA or DGPS, Com port two is for NMEA output only.

Comunications port one uses the yellow wire wire for transmit, the orange wire for receive. Comunications port two uses the blue wire for transmit. Both ports use the shield wire for signal ground.

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