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.

4 Troubleshooting

If you notice unexpected operation of the Maretron J2K100, follow the troubleshooting

procedures in this section to remedy simple problems. If these steps do not solve your

problem, please contact Maretron Technical Support (refer to Section 6 for contact

information).

Symptom Troubleshooting Procedure

No engine, transmission

or genset data visible on

NMEA 2000

network.

Ensure that the J1939 network is operational by observing J1939

gauges or displays. You should see information transmitted from

the engine, transmission, or genset displayed on the J1939

displays. If you don’t see data, try disconnecting the J1939

connection you made to the J2K100 as something may have been

connected incorrectly.

Once you are sure that the J1939 network is operational with a

J2K100 connected, ensure that the NMEA 2000

network is

operational by observing displays. You should see information

from components besides the ones attached to the J2K100 which

verifies an operational NMEA 2000

network. If you don’t see data,

try disconnecting the NMEA 2000 connection you made to the

J2K100 as something may have been connected incorrectly.

Once you are sure that the J1939 and NMEA 2000 networks are

operational with a connected J2K100, ensure that the NMEA

2000

connector is securely connected to the NMEA 2000

network and the J1939 connector is securely connected to the

J1939 network.

Ensure that the J2K100 has the appropriate NMEA 2000

PGNs

enabled as described in Section 2.5.5.

Ensure that the J2K100 is programmed with an engine or

transmission J1939 source address that corresponds to the J1939

source addressed used by the connected engine or genset as

described in Section 2.5.1.
