Maretron J2K100 User Manual
J1939 to NMEA 2000
J2K100
Maretron’s J2K100 attaches directly into
J1939 networks of compatible engines,
transmissions, and gensets and converts
the J1939 data to the new marine digital
interface (NMEA 2000
transmission, and genset data is then
distributed throughout the vessel over a
single cable where it can be monitored by
any NMEA 2000
®
). Critical engine,

The J2K100 converts the
following information:
The J2K100 can also be used as part of a
complete fuel computer. Simply connect the
J2K100 together with Maretron universal
displays (DSM200/DSM250/N2KView
GPS antenna/receiver (GPS100) and you
have a system capable of displaying gallons
per hour and/or miles per gallon.
