![]() And certainly not an event that requires an "installer." I think YouTube is doing a pretty good job already at exposing the secrets behind the curtain in many areas, and so it will for marine electronics installation. NMEA 2000 devices will drain your battery if the NMEA 2000 power cable is connected to the battery. NOTICE If you are installing a NMEA 2000 power cable, you must connect it to the boat ignition switch or through another in-line switch. FREE Shipping on orders over 25 shipped by Amazon. Connect the VHF antenna cable to the VHF ANT port on the Garmin AIS 800 device. I've spent the past 32 years of my life leading hundreds of men and women around the world in 3 separate wars, ensuring thousands of others died for their country or belief so that we can protect ours, so I don't suspect that the installation of a GPS unit on a small pleasure craft will be a major life event. NMEA 2000 (N2K) 1/2 Meter, Backbone or Drop, Cable for Lowrance Simrad B&G Navico Garmin Networks. Unless you are connecting "backwards" to other 0183 devices, there should be no technical reason to use that port, especially not just for 2 wires feeding power, that's just clearly an in-between standards design flaw.ĭon't worry Ben, I don't blame others for my temporary knowledge gap, that's why I'm posting on here to close that gap. However, all of my other GARMIN instruments including the hull transducer, 2 separate displays, and the computer control box are powered through the network, and it's simply a matter of time until they improve the cabling to push enough power through the network to all devices. Unfortunately GARMIN does not clearly label this fact on the 547 install manual. The fact is that NMEA 2000 backbones which are connected to a 12V source have the ability to power "some" devices and not others. ![]() The problem is that the marine industry is only incrementally moving forward in basic networking and currently living between two standards. Don't be scared Ben, it's all just networking fundamentals which I have an above-average skill in so I'm sure I'll work though it. ![]()
