The digital reads it just fine, and when I'm plugged into the diagnostic cable the computer reads rpm accurately. You can connect power either at the end of your NMEA 2000 network or in the middle. Make sure to connect the NMEA 2000 power cable to the top of a T-connector never connect the NMEA 2000 power cable to the side of a T-connector. When I ran the engine (with the plotters off), the analog rpm gauge was not responding. The Garmin NMEA 2000 power cable connects to a T-connector like other drop cables.
Do I need to look into a power isolator? I only ask because: When I turn the Garmin units on, the I-Command gauges continually restart until the plotters are off again. As wired now, the Garmins are recognizing the EMM off the E-Tec 250 outboard in addition to a couple other devices (SeaStar, and unknown), but still not properly registering gauge information (reads battery voltage too high). The NMEA power has a port, there are terminators on both ends of the backbone, and the final drop cable is running to a terminal strip to connect to the I-Command pin labelled 'To: NMEA Accessory' (4 wire: Can Hi, Can Lo, NMEA+, and NMEA-).
#GARMIN NMEA 2000 WIRING PLUS#
I have two Garmin Echomap Plus plotters running to an NMEA 2000 backbone with 4 ports. The NMEA power has a port, there are terminators on both ends of the backbone, and the final drop cable is running to a terminal strip to connect to the I-Command pin labelled "To: NMEA Accessory" (4 wire: Can Hi, Can Lo, NMEA+, and NMEA-). It'll be pretty dope when it's done but this NMEA 2000 is tripping me up. I have two Garmin Echomap Plus plotters running to an NMEA 2000 backbone with 4 ports. without using a NMEA 2000 Starter kit (the square gauges are already on a NMEA 2000 backbone - it just uses Yamahas proprietary wiring) You will need either an adapter cable (NMEA 2000 on one end for the Garmin, Yamahas plug on the other) and some additional wiring to to make space to plug it it, along with your square gauge wiring or you. Contact engine manufacturer for the most current NMEA 2000® compatibility information.
This data can be viewed on any multifunction display (MFD) and digital gauge shown below. It'll be pretty dope when it's done but this NMEA 2000 is tripping me up. output engine data with an interface connection to an onboard NMEA 2000® network. I walked into this project halfway, with parts already purchased for a Frankenstein of a sports fishing boat.
