J2K100 User’s Manual Page 6 Revision 1.0 2.5.1 J1939 Source Address Selection The J2K100 connects into a J1939 network and translates messages from a single J1939 device into NMEA 2000 ® messages. By default, the J2K100 only translates J1939 messages from a J1939 device with a source address of zero.
® ® Revision 1.0 Page 7 NMEA 2000 ® PGNs. For example, if the J2K100 rece ives engine related messages from the J1939 network but no transmission or genset me ssages, then the J2K100 will generate the corresponding NMEA 2000 ® engine PGNs but it will not transmit any NMEA 2000 ® transmission or genset messages.
