Appendix B – Application Note

Interfacing J1939 Engines and/or Gensets to an

NMEA 2000

®

Network Using Maretron’s J1939 to

NMEA 2000

®

Gateway (J2K100)

Warning: Improper installation of the Maretron J2K100 may prevent existing engine
accessories (i.e., engine gauge displays, key switches, throttle and shift controls, etc.) from
working properly. You must have an understanding of J1939 data networks before attempting
to install the J2K100. Maretron strongly recommends that you understand SAE documents
J1939-11 and J1939-15 (see Section 3.1 of this appendix) before attempting to install the
J2K100 and that you consult the engine/genset manufacturer for their recommendations
before connecting anything to the J1939 network.
