[TG] [TG11] SeaTalk1 to NMEA 2000

RE: [TG11] SeaTalk1 to NMEA 2000
We don't offer field-attachable STNG (or any other) connector because we don't want to encourage re-termination of cables in a marine environment, for reasons of both EMC compliance and environmental (moisture, vibration) tolerance and reliability - we wouldn't expect them to be reliably and consistently crimped using proper tools, by proper techs, as RJ45 ought to be.

Unfortunately in the particular (and relatively rare) case where you want to use a mixed backbone of STNG and Devicenet cabling, I believe that joining the cables (or fitting a field-attachable Devicenet connector onto an STNG backbone) is by far preferable to using a Devicenet-STNG spur adaptor cable plugged into an STNG spur socket, for the reasons I mentioned.

NMEA2000 is low-speed and deliberately robust in its signalling (compared to ethernet - CANbus was designed for industrial and automotive applications in very harsh environments) and you can get away with a cable join that would not work at all on ethernet.

Please don't PM me asking for direct support, please ask a public question instead so that others can see the question and answer. Forum posts will always be answered before PM requests.
