NMEA 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 SeaCharter 500CDF and receive positioning information. The SeaCharter 500CDF is capable of exchanging information with any device that transmits or receives NMEA 0183 data. This feature re- quires an optional accessory cable.

NMEA Wiring

To exchange NMEA data, the unit has one NMEA 0183 version 2.0 communication port. Com port one (Com-1) can be used to receive NMEA format GPS data. The com port can also transmit NMEA format GPS data to another device.

The optional data cable will contain three wires. Com-1 uses the yellow wire to transmit, the orange wire to receive and the shield wire for sig- nal ground.

Read your other product’s owner’s manual for more wiring information.

MMC or SD Card Memory Card Installation

Your unit uses a MultiMedia Card to store information, such as sonar logs, custom maps, waypoints, trails and other GPS data. The unit can also use Secure Digital Cards (SD card) to store data.

NOTE:

Throughout this manual, we will use the term MMC, but just re- member that your unit can use an MMC or SD card to store data.
