Because Seatalk NG and DeviceNet are electrically similar the considerations about length limits and the like are the same for both networks. If you experience difficulty installing a NMEA 2000 network, contact Garmin Product Support or a certified NMEA 2000 technician. This guide provides descriptions of the NMEA 2000 connectors and cables sold by Garmin, and the fundamental concepts of installing a NMEA 2000 network on your boat. You can even buy the hybrid cables, but they come in fixed lengths which isn’t always what is needed. A NMEA 2000 network is made of connected NMEA 2000 devices that communicate using basic plug-and-play connectivity. Maretron has published a great cabling guide in general that discusses some of the general considerations for a NMEA-2000 DeviceNet network. So the bottom line is that (except for some exotic devices) slicing and dicing of cables should work for any brand of NMEA 2000 compatible network. Because Seatalk NG and DeviceNet are electrically similar the considerations about length. Maretron has published a great cabling guide in general that discusses some of the general considerations for a NMEA-2000 DeviceNet network. My current network was built with all Seatalk NG so I haven't taken my own advice and ripped out the whole network.

Maretron NMEA 2000® Cables & Connectors About NMEA 2000® Cables and Connectors The NMEA 2000® standard goes beyond defining message content and includes requirements for the cabling used to interconnect electronic components (referred to as the physical interface). Unfortunately, Raymarine doesn't currently make an NMEA-2000 DeviceNet to Seatalk NG backbone adapter though they say they're developing one.īecause there aren't backbone converters and because Raymarine is also moving from Seatalk NG to DeviceNet I prefer to build an all DeviceNet network and then use spur adapter cables to connect Seatalk NG devices. Nothing coming off a spur should ever have a terminator on it, those should only be at the end of the backbone and NMEA-2000 spec limits any single spur to 6 meters and the total length of spur cables on the network to 78 meters. Our NMEA 2000 network updater provides the convenience of updating Garmin products and NMEA 2000 accessories that do not have an SD card slot.
Raymarine uses different connectors for backbone (blue ends and stripe on the cable) and spur connectors (white ends and stripe).

Simply download a software update to an SD card and insert the card into the network updater. The part number Steve referenced above (A06045) is a spur adapter, not a backbone adapter.
