You must configure the SIM100 as to what type of switch circuit it is monitoring. The allowable
values for this parameter are as follows:
• “End of Line Resistor” (default) – The switch circuit has a SPST switch connecting the A
and B terminals, with a parallel 8 KΩ end-of-line resistor. This allows the SIM100 to
monitor the circuit and indicate an error condition if the monitored circuit somehow
becomes disconnected from the terminals on the SIM100.
• “No End of Line Resistor” – The switch circuit has a SPST switch connecting the A and
B terminals, with a no parallel end-of-line resistor. The SIM100 is not able to monitor the
circuit for disconnection in this case.
• “Disable” – Use this value if no switch circuit is connected to the corresponding switch
terminals. The SIM100 will indicate that no data is available for this circuit.
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. 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.
