NMEA 2000

PGNs. For example, if the J2K100 receives engine related messages from the
J1939 network but no transmission or genset messages, then the J2K100 will generate the
corresponding NMEA 2000
®
engine PGNs but it will not transmit any NMEA 2000
®
transmission or genset messages. As another example, let’s say that there is an engine and a
genset connected to the J1939 network yet we are only interested in having the engine
messages translated to corresponding NMEA 2000
®
PGNs. In this case, the J2K100 can be
configured to enable engine PGNs while disabling genset PGNs. You can 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.
3 Maintenance
Regular maintenance is important to ensure continued proper operation of the Maretron
J2K100. Perform the following tasks periodically:
• Clean the unit with a soft cloth. Do not use chemical cleaners as they may remove
paint or markings or may corrode the J2K100 enclosure or seals.
• Ensure that the unit is mounted securely and cannot be moved relative to the mounting
surface. If the unit is loose, tighten the mounting screws.
• Check the security of the cable connected to the NMEA 2000
®
and J1939 connectors
and tighten if necessary.
