Yacht Devices J1708 Engine Gateway For 2000 Volvo TAMD74
From your article where you used the Yacht Devices J1708 gateway for your 2004 Volvos is it safe to assume this device will support my 2000 Volvo TAMD74 engines to display data on a Raymarine e125 MFD? Can the output from the J1708 tie directly into the Wi-Fi gateway to pull up the data on the MFD using the MFD’s internal Wi-Fi capability or do I need to run a cable from the J1708 gateway all the way to the helm (likely less than a 20’ run) to integrate into the onboard seatalk network? If the long cable is needed can you also recommend a Seatalk extension cable to interface between the J1708 gateway and the network hub? Thank you for the great article, Ben!
First, it's not possible to leverage the e125's internal WiFi to receive NMEA 2000 data. That's a limitation of the e125 (and most other MFDs). It is possible to use two YDWGs as WiFi bridges of a NMEA 2000 network. Real-world experience suggests that's needless complexity compared to running a cable. The best thing to do is extend the backbone of your NMEA 2000 (or in this case SeaTalk NG) network. To do this (assuming you have a SeaTalk NG network) you will remove one of the blue, bullet-shaped terminators and replace it with a SeaTalk NG backbone cable. Then, on the other end, in the engine compartment, you will connect to either a SeaTalk NG tee connector or a A06064 5-way block ( https://www.raymarine.com/view/index-id=5536.html). Now, you can connect the YDES to the network.
@ben-stein Thank you for the detailed response. Looking forward to tackling this in June.
