If the old coolant temperature gauge (upper left) fails, for instance, the EMU will still deliver the temp information if the sender is working, at least theoretically…and if the EMU or N2K network fail, the gauge will still work. Incidentally, one neat nuance of the EMU-1 is that each of its 6 gauge channels can automatically sense the presence of an analog sibling, adjusting its calibration curve to suit and also sending power to the sender if needed.
I’m too conservative to totally remove Gizmo’s old gauges (like the set above at the lower helm), but I’m already confident enough of the EMU-1 data that I plan to move them to an obscure location when I do a “glass bridge” makeover this winter. I’m going to be better informed about my engine’s health, which is very important, while also gaining some scarce helm panel real estate for better uses than dumb analog gauges… That Actisense EMU-1 is now converting the analog gauge data from the boat’s 14-year-old Volvo Penta diesel into NMEA 2000 messages that can be displayed in multiple ways on most any MFD or instrument screen on board and can also be custom alarmed and logged. Having multiple sources of power can create a potential for ground loops, if not wired correctly.It’s great to test an unusual device that promises to do something new and desirable for the good vessel Gizmo and find out that it installs fairly easily and works quite well.
#4 If the SeaTalk 1 network was already powered, and you are connecting to an already powered NMEA 2000 network, you’ll need to disconnected the red power feed wire for the SeaTalk 1 network. We’ve seen DIY installations using numerous terminators and no, the systems were not working correctly. One terminator at each end of the back-bone. #3 IMPORTANT: Only two terminators are allowed per NMEA 2000 network. Terminators are only used at either end of a back bone! For empty drop ports you can use Raymarine blanking plugs in the SeaTalk ng drop ports or NMEA 2000 blanking caps to protect any unused future expansion ports on an NMEA 2000 bus. #2 If the E22158 converter is the end of a back bone, as shown here, a blue terminator would be used. #1 If the E22158 converter is used only as a drop device, to port SeaTalk 1 over to NMEA 2000, and is not at the end of a back bone, or in a backbone, you would not use any terminators in the blue ports.
BECU NMEA 2000 CONNECTORS UPGRADE
The total cost for this upgrade will run you slightly over $100.00 in order to get your SeaTalk 1 data converted over to NMEA 2000 based electronics. This wiring puts the SeaTalk 1 data onto the NMEA 2000 Garmin chart plotter. In the image above we are connecting a customers SeaTalk 1 instruments to an NMEA 2000 Garmin chart plotter. Getting from SeaTalk 1 to SeaTalk ng / NMEA 2000 requires a proper electronic language conversion.Ĭonnection to a standard NMEA 2000 network will look similar to this: WARNING: We have seen a number of individuals physically damage equipment or disable a complete NMEA 2000 system by trying to hard-wire an older SeaTalk 1 network to SeaTalk ng or NMEA 2000 networks. The device below is actually a small processor running software. This converter is not just a busbar or fancy terminals strip, as some have described it.
BECU NMEA 2000 CONNECTORS SOFTWARE
The SeaTalk 1 to SeaTalk ng converter is actually a small electronic signal converter that has operational software doing the conversion. Once your SeaTalk 1 data is converted into SeaTalk ng / NMEA 2000 the conversion & connection to the rest of the vessels NMEA 2000 bus is much easier. Female SeaTalk ng to NMEA 2000 = A06045Ī lot of boat owners don’t realize that Raymarine’s SeaTalk ng is essentially NMEA 2000 that is using Raymarine’s proprietary SeaTalk ng cables/connectors.A male or female SeaTalk ng to NMEA 2000 drop cable:.Raymarine E22158 SeaTalk 1 to SeaTalk ng conversion kit (see image above).You can purchase the Raymarine SeaTalk 1 to SeaTalk ng Converter Kit here: Raymarine SeaTalk 1 to SeaTalk ng Converter Kit (LINK) Purchases from our web store help keep this site FREE! Site Plug:The SeaTalk 1 to SeaTalk ng Converter Kit can be purchased from the web store. The conversion from SeaTalk 1 to SeaTalk ng / NMEA 2000 is actually pretty simple once you have the Raymarine E22158 converter kit: The article deals specifically with older Raymarine products that operate on the proprietary SeaTalk 1 network. We get asked this electronics question more than just about any other, from customers who have a perfectly operating SeaTalk 1 network and want to add the SeaTalk 1 data to the NMEA 2000 bus.
