Congratulations on your purchase of the Maretron J1939 to NMEA 2000

®

 Gateway (J2K100).  

Maretron has designed and built your gateway to the highest standards for years of 
dependable and accurate service.  

 

Maretron’s J2K100 is a gateway for bridging J1939-equipped engines and gensets with an 
NMEA 2000

®

 network. The gateway automatically converts incoming J1939 messages to 

NMEA 2000

®

 messages so you can monitor your J1939-equipped engines, transmissions, or 

gensets with networked NMEA 2000

®

 displays such as the Maretron DSM200.  

 

The Maretron J2K100 is designed to operate within the harsh demands of the marine
