2 of 12
The Offshore System’s NMEA2000® 3185, J1939 to NMEA2000® Adaptor is designed to convert
Engine, Transmission and Generator messages on the J1939 network onto the NMEA2000®
network.
This unit is designed to operate in a protected marine environment such as an engine room. It is
very important that it is installed and set up correctly according to this manual. Please read and
follow the installation and setup instructions carefully to achieve the best results.
1.1 Firmware Revision
The information in this manual corresponds to rmware revision 1.1.3
1.2 Product Features
The 3185, J1939 to NMEA2000® Adaptor has the following features:
• Connection to J1939 network using a 3 pole Wago cage clamp connector
• Green LED conrming valid J1939 message reception.
• NMEA2000® micro C interface plug
• User Settable a NMEA2000® Device Instance using rotary switch
• Blue LED conrming NMEA2000® transmission
• NMEA2000® Interface optically isolated from J1939
• Power drawn only from NMEA2000® interface
• Panel or DIN rail mounting option
NOTE:
FOR SAFETY REASONS THIS UNIT DOES NOT HAVE THE CAPABILITY OF TRANSMITTING ANY
MESSAGES ONTO THE J1939 NETWORK.

2.1 Unpacking the box
You should nd the following items in the 3185 shipping box:
1 x 3185 J1939 to NMEA2000® Adaptor
1 x Din Rail mounting Kit with 2 rail mounts and 4 countersunk M3 screws for rails
1 x 3185 User Manual (This document)
2.2 Mounting the unit
The unit can either be mounted to a at surface using 4 mounting screws. The unit dimensions
and mounting hole locations are shown on the following drawing.
Or the unit can be Din Rails mounted by attaching the Din Rail mounts to the case using the
supplied M3 CSK screws and then clipping the unit to the Din Rail
2.3 Connecting the NMEA2000® Cable
The unit is connected to the NMEA2000® network by the 5 way micro C socket on the front.
Carefully attach the network drop cable to this plug and hand tighten until it it is fully seated.
Take care to match the orientation of the pip inside the socket to the recess inside the drop
cable plug. The other end of the drop cable should be connected to a suitable Tee connector on
the NMEA2000® network backbone cable.

2.4 Connecting the J1939 cable to the WAGO socket
The cables from the power-source to the external sockets are connected using the WAGO Cage
Clamp terminal block. The wire should be stripped for 8mm and then the cage clamp opened
with a small screwdriver in the slot above the wire connection. Then simply insert the wire into
it’s connection slot and release the cage clamp by removing the small screw driver. This will
produce a secure gas tight connection on wire sizes from 0.08 – 1.5 mm²
2.5 J1939 Connections
The terminal connections are numbered as follows:
These are marked on the unit case.
Terminal 1 CAN H (HIGH-level J1939 CAN bus line)
Terminal 2 Ground
Terminal 3 CAN L (LOW-level J1939 CAN bus line)

The following two items can be congured directly on the 3185 using the two small rotary
switches. There are no other menu setups to worry about.
3.1 J1939 Source
The J1939 Source dial is now redundant to the design and does not require setting to a specic
setting. Dial can be set to 0 as a precaution.
3.2 NMEA2000® Device Instance
Each 3185 J1939 to NMEA2000® Adaptor connected to the NMEA2000® network needs to have
a unique Device Instance Address. The Device Instance of each unit is set by turning the small
rotary switch with a small screw driver. Valid Device Instances range from “0” through to “F”.
