3 Maintenance
Regular maintenance is important to ensure continued proper operation of the Maretron
USB100. 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 USB100 enclosure or seals. Do not use any
cleaners containing acetone, as they will deteriorate the plastic enclosure.
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 USB interfaces and
tighten if necessary.
4 Troubleshooting
If you notice unexpected operation of the Maretron USB100, follow the troubleshooting
procedures in this section to remedy simple problems.
Symptom Troubleshooting Procedure
No data output on USB interface Check the connections to the NMEA 2000 and USB
connectors and tighten if necessary
Ensure that power is supplied to the connected
NMEA 2000 cable
Ensure that the correct serial port is selected by the
software expecting NMEA 0183 format data. Open
the Device Manager and ensure that the selected
port is labeled “Maretron NMEA 2000 USB
Gateway” rather than “Standard COM port”.
If these steps do not solve your problem, please contact Maretron Technical Support (refer to
Section 6 for contact information).
Warning: There are no user-serviceable components inside the Maretron USB100. Opening
the USB100 will expose the sensitive electronic components to adverse environmental
conditions that may render the unit inoperative. Please do not open the USB100, as this will
automatically void the warranty. If service is required, please return the unit to an authorized
Maretron service location.
