J1939 to NMEA2000® Adaptor

The Offshore Systems 3185 J1939 to NMEA2000® Adaptor takes standard J1939 engine and transmission messages and transmits them onto the NMEA2000® network.

The J1939 interface is optically isolated to prevent ground loop problems and is read only so no messages are sent to the J1939 interface for absolute safety.

The Adaptor is equipped with leds to indicate when J1939 messages are received and when NMEA2000® messages are transmitted

It is compatible with either 12 or 24 Volt systems and requires NO user setup menus but the simple setting of two small rotary source and address switches so multiple Adaptors can exist on the same networks.

The J1939 connections to the unit are made via boat builder preferred WAGO Cage Clamp terminal blocks which allow either solid or multi stranded wires from 0.08 to 1.5mm² to be connected quickly and securely.

The 3185 can be either panel mounted or din rail mounted using the din rail mounting clips provided.

The unit comes with a detailed User Manual and is certified to work with NMEA2000®.

The 3185 J1939 Adaptor is an important part of our complete NMEA2000® Vessel Monitoring and Control System.
