Because Seatalk NG and DeviceNet are electrically similar the considerations about length limits and the like are the same for both networks.

The plug-and-play interface allows devices made by different manufacturers to communicate with each other within the same network without causing interference between devices. However, that does NOT mean that all NMEA 2000 cables are identical or equivalent to all other NMEA 2000 cables. Maretron has published a great cabling guide in general that discusses some of the general considerations for a NMEA-2000 DeviceNet network. .NMEA 2000 Micro Gender Changer Cable (female to female) A2K-GCF-0M25 An Actisense gender changer can be used between two cable connectors of. NMEA 2000 is a plug-and-play communications standard used for connecting marine instrumentation within vessels. In terms of physical construction, there is no hard-and-fast difference. My current network was built with all Seatalk NG so I haven't taken my own advice and ripped out the whole network. NMEA 2000 is more like Ethernet networking.
#DIFFERANCE BETWEEN NMEA 2000 CONNECTORS SERIAL#
NMEA 0183 is like serial communications that old computers used. Communication runs at 250 kilobits-per-second and allows any sensor to talk to any display unit or other device compatible with NMEA 2000 protocols. They are not 'languages' but really specify the electrical connection between two (or more) devices. 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. NMEA 2000, abbreviated to NMEA2k or N2K and standardised as IEC 61162-3, is a plug-and-play communications standard used for connecting marine sensors and display units within ships and boats. 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. Raymarine uses different connectors for backbone (blue ends and stripe on the cable) and spur connectors (white ends and stripe). The part number Steve referenced above (A06045) is a spur adapter, not a backbone adapter.
