2.5.8 Advanced Configuration…
Certain parameters do not normally need to be set in order for normal operation, but are included in an advanced configuration section for use in special situations.
2.5.9 NMEA 2000® PGN Enable/Disable
The SIM100 is capable of transmitting NMEA 2000® messages (or PGNs) associated with monitored switch circuits. You may individually enable or disable each of these messages. You may also change the rate of transmission of each of these messages if desired.
2.5.10 Restore Factory Defaults
Selecting this configuration option causes all stored parameters in the SIM100 to be reset to the values they contained when the unit was manufactured.
3 Maintenance
Regular maintenance is important to ensure continued proper operation of the Maretron SIM100. 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 SIM100 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® connector, and tighten if necessary.
•Check the security of all of the switch connections on the top of the unit and tighten if necessary.
