NOTES:
• The diagram shows only the NMEA 2000 data connection to the GPSMAP 4000/5000 series chartplotter. The chartplotter must also be
connected to power or it will not function. See page 9.
• One GPS antenna will provide position data for every device on the NMEA 2000 network. Do not connect multiple GPS antennas if you are
using multiple chartplotters.
