J2K100 User’s Manual

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. If the J1939 source address of the engine, transmission, or genset to be monitored is different than zero, then the J2K100 must be programmed with the appropriate J1939 source address. This can be done with the Maretron DSM200 display or other NMEA 2000® display unit that is capable of configuring the J2K100. Please refer to the Maretron DSM200 User’s Manual for details.

2.5.2 NMEA 2000® Engine Instance Selection

NMEA 2000® provides a unique engine instance for each engine on a vessel. Single engine vessels use engine instance zero (0) while dual engine vessels use engine instance zero (0) for the port engine and engine instance one (1) for the starboard engine. By default the J2K100 uses engine instance zero (0). If you are installing the J2K100 on a single engine vessel, then you don’t have to configure this parameter. However, if you install two J2K100s for dual engine vessels, then you will need to configure the starboard engine J2K100 to use engine instance one (1). You configure the J2K100 using a Maretron DSM200 display or other NMEA 2000® display unit that is capable of configuring the J2K100. Please refer to the Maretron DSM200 User’s Manual for details.

2.5.3 NMEA 2000® Transmission Instance Selection

NMEA 2000® provides a unique transmission instance for each transmission on a vessel. Single transmission vessels use transmission instance zero (0) while dual transmission vessels use transmission instance zero (0) for the port transmission and transmission instance one (1) for the starboard transmission. By default the J2K100 uses transmission instance zero

(0). If you are installing the J2K100 on a single transmission vessel, then you don’t have to configure this parameter. However, if you install two J2K100s for dual transmission vessels, then you will need to configure the starboard transmission J2K100 to use transmission instance one (1). You configure the J2K100 using a Maretron DSM200 display or other NMEA 2000® display unit that is capable of configuring the J2K100. Please refer to the Maretron DSM200 User’s Manual for details.

2.5.4 J1939 Diagnostic Messages Enable/Disable

The J2K100 is capable of re-broadcasting J1939 diagnostic messages output by the monitored engine, transmission, or genset onto the NMEA 2000® network. As shipped from the factory, the J2K100 does not transmit J1939 diagnostic messages over the NMEA 2000® network. If this behavior is desired, it may be enabled with the Maretron DSM200 display or other NMEA 2000® display unit that is capable of configuring the J2K100. Please refer to the Maretron DSM200 User’s Manual for details.

2.5.5 NMEA 2000® PGN Enable/Disable

The J2K100 is capable of transmitting several different kinds of NMEA 2000® messages (or PGNs) associated with engines, transmissions, and gensets. The J2K100 automatically detects incoming messages from the J1939 network and translates them into corresponding
