Garmin GPSMAP 3205 Installation Instructions - Page 6

Power/Data Cable Wiring The following pages contain several wiring diagrams. The first diagram on the next page is a simple diagram showing the GPSMAP 3000 series chartplotter using the 18-pin Power/data cable and the GPS 17x. If two or more GPSMAP 3000, 4000, or 5000 series chartplotters are installed and networked, only one GPS 17x antenna needs to be installed. Next are wiring diagram examples showing the GPSMAP 3000 using the 18-pin Power/Data wiring harness interfacing with a variety of different equipment. Refer to the wiring diagram that best suits your needs. For third-party devices, refer to the wiring guidelines included with that equipment. Use 22 AWG (18 AWG for the Red and Black wires), shielded, twisted-pair wiring for extended runs of wire. Solder all connections and seal the connection with heat shrink tubing. If networking two or more chartplotters, the GPS 17x and NMEA input devices should only be attached to one chartplotter on the network. A pinout of the cable is shown below. Power/Data Cable Input/Output Ports The GPSMAP 3000 series Power/data cable has four I/O (Input/Output) ports. Ports 1 and 2-communicate with other NMEA-compliant devices, such as VHF radios, NMEA instruments, autopilots, or PCs (Port 1 only). You can input one NMEA device to each port, and output in parallel to three NMEA devices per port. Port 3-is reserved for use with Garmin sounder modules. Port 4-is reserved for use with the Garmin GPS 17x GPS antenna. The following formats are supported for connection of external devices: Garmin proprietary sonar module and NMEA 0183 version 3.01. The following are the sentences for NMEA 0183, version 3.01 and later output: Approved sentences-GPBWC, GPRMC, GPGGA, GPGSA, GPGSV, GPGLL, GPBOD, GPRMB, GPRTE, GPVTG, GPWPL, and GPXTE Garmin proprietary sentences-PGRME, PGRMM, PGRMZ, and PSLIB The unit also includes NMEA input with support for the WPL sentence, DSC, and sonar NMEA input with support for the DPT (Depth) or DBT, MTW (Water Temp), and VHW (Water, Speed, and Heading) sentences. The unit interface must be set to NMEA In/NMEA Out. Documentation concerning NMEA and RTCM formats and sentences are available for purchase from: National Marine Electronics Association (NMEA) Seven Riggs Avenue Severna Park, MD 21146 U.S.A. www.nmea.org Function Color DC power input Red Ground (Power/data) Black Port 1: Data in (Rx) Brown Port 1: Data out (Tx) Blue Port 2: Data in (Rx) Violet Port 2: Data out (Tx) Gray Port 3: Data in (Rx) White/Brown Port 3: Data out (Tx) White/Blue Accessory on signal Orange Port 4: Data in (GPS 17x) White Port 4: Data out (GPS 17x) Green Alarm low signal Yellow No function No color Pin # 15 18 16 17 9 10 4 5 6 13 14 11 1,2,3,7,8,12 Power/Data(NMEA) Cable 2 1 6543 11 10 9 8 7 15 14 13 12 18 17 16 Cable End View  GPSMAP 3000 Series Installation Instructions
