® 1 Introduction Congratulations on your purchase of the Maretron Switch Indicator Module. Maretron has designed and built your SIM100 to the highest standards for years of dependable and accurate service. Maretron’s Switch Indicator Module monitors switch closure devices including, but not limited to, safety equipment (e.g., heat, smoke, carbon monoxide, explosive vapor detectors), security systems (e.g.

® 3. The SIM100 is temperature-rated to 55°C (130°F), so it should be mounted away from engines or engine rooms where the operating temperature exceeds the specified limit. 2.3 Mounting the SIM100 Attach the SIM100 securely to the vessel using the included stainless steel mounting screws or other fasteners as shown in Figure 1 below. Do not use threadlocking compounds containing methacrylate ester, such as Loctite Red (271), as they will cause stress cracking of the plastic enclosure.
SIM100 User's Manual Figure 2 – NMEA 2000® Connector Face Views 2.4.2 Switch Connections The SIM100 switch connections are made by connecting to the 12-pin terminal strip on the top of the unit. First, remove the four screws at the corners of the unit detaching the splash guard from the unit. On the bottom of the splash guard, you will find a label detailing the wire connection to pin number assignments, which are repeated in the table below.
® 2.4.2.1 Switch With End of Line Resistor Installing an end of line resistor as close to the switch as possible allows the SIM100 to detect if the signal wires have been disconnected due to either corrosion, tampering, or for any other reason. This allows the SIM100 to report over the NMEA 2000 network if the sensor has become disconnected in addition to the normal closed and open indications. Please refer to Figure 3 for connecting the SIM100 to a switch with an end of line resistor.

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.
SIM100 User's Manual • • 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. 4 Troubleshooting If you notice unexpected operation of the Maretron SIM100, 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).
