[LW] [LW11]AIS650 Crashing NMEA2000 Network

[aquabelle]

My 650 is running the latest software version and when inspected with ProAIS-2, gets a completely clean bill of health. However, when I use the (correct) adapter cable to from the SeaTalkng connector to my NMEA2000 network, the whole network crashes.

o N2K devices from Simrad, Furuno, Airmar and RosePoint are on the network and all work fine

o I have swapped out T-connectors, resistors and cables with no effect

o the total LEN rating of the network is modest and dropping another transducer from the network to lower the LEN and then re-booting with the 650 connected, makes no difference: the N2K network crashes.

In looking through other posts, I see two other users who report this same effect. In those cases, the advice was to send the 650 in to a Service Centre. Given the above, anything else I can/should try...or is it a send-it-in case? Is this a known issue?

thanks

Dear Auqabelle,

While not particularly common, SeaTalkng / NMEA 2000 can fail in a manner which will crash the SeaTalkng/NMEA 2000 backbone. It is recommended that you verify that the AIS650 and the other devices which have been interfaced to the SeaTalkng / NMEA 2000 backbone have each been updated with the respective latest available Raymarine product software update.
If so, and should the problem persist, then it is recommended that the AIS650 be sent to Raymarine’s Product Repair Center to be bench checked / serviced along with the adaptor cable.
In the interim, should the system feature a MFD having a NMEA 0183 input port, then you may want to consider interfacing the AIS650's 38400 BAUD NMEA 0183 leads to the MFD's NMEA 0183 leads to support bidirectional communications with the AIS650 to permit its Silent Mode feature to be configured on/off. The corresponding NMEA 0183 port of the MFD would then need to be configure to "AIS 38400".

Many Thanks
