Garmin GPSMAP 600 Installation Instructions Manual page 7

Connecting the Power/Data Cable to a NMEA 0183 Device (Optional)
You can connect the GPSMAP 600 series flush-mount bracket to NMEA 0183-compatible electronic equipment, such as a VHF radio, using
the power/data cable. The GPSMAP 600 series device has two NMEA 0183 ports, and it can communicate with two NMEA 0183-compatible
devices. Refer to the wiring diagram for connecting the power/data cable to NMEA 0183-compatible devices.
Notes:
• When wiring NMEA 0183 devices for two-way communication, use the corresponding TX and RX wires for each port. For example, if you
use the port 1 TX wire (yellow), you must also use the port 1 RX wire (blue). Likewise, if you use the port 2 TX wire (brown), you must
also use the port 2 RX wire (white).
• If the NMEA 0183 device you are wiring only transmits or only receives (one-way communication), connect the appropriate RX or TX wire
from the marine-mount bracket, and leave the other wire on the port unconnected.
• Refer to the manufacturer's instructions for your NMEA 0183 device for wire identification and configuration information.
• If it is necessary to extend NMEA 0183 wires, use 28 AWG wire.
