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., motion, vibration, glass break, door and port hole magnetic switches), and
vessel monitoring equipment (e.g., valve closed/open, high water bilge). The SIM100
continually monitors these switch closure devices and broadcasts information over the NMEA
2000 network about the switch state so the crew can be alerted to potential conditions or
problems that warrant further investigation. Advanced features of the SIM100 include the
ability to detect whether or not power has been disconnected from the monitored device or if
the signal wires have been disconnected due to either corrosion, tampering, or for any other
reason (if the monitored device is so equipped). With the SIM100, you can rest assured that
critical sensors are receiving power, signal wires are connected, and all the safety, security
and vessel functions are under constant supervision.
The Maretron SIM100 is designed to operate within the harsh demands of the marine
environment. However, no piece of marine electronic equipment can function properly unless
installed, configured, and maintained in the correct manner. Please read carefully and follow
these instructions for installation, configuration, and usage of the Maretron SIM100 in order to
ensure optimal performance.

1.4 Quick Install
Installing the Maretron SIM100 involves the following five steps. Please refer to the individual
sections for additional details.
2 Installation
2.1 Unpacking the Box
When unpacking the box containing the Maretron SIM100, you should find the following items:
1 – SIM100 – Switch Indicator Module
1 – Parts Bag containing 4 Stainless Steel Mounting Screws
1 – SIM100 User’s Manual
1 – Warranty Registration Card
If any of these items are missing or damaged, please contact Maretron.
2.2 Choosing a Mounting Location
Please consider the following when choosing a mounting location.
1. The SIM100 is waterproof, so it can be mounted in a damp or dry location.
2. The orientation is not important, so the SIM100 can be mounted on a horizontal deck,
vertical bulkhead, or upside down if desired.
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
Figure 1 – Mounting the SIM100
2.4 Connecting the SIM100
The SIM100 requires two types of electrical connections: 1) the NMEA 2000® connection (refer
2.4.1 NMEA 2000® Connection
The NMEA 2000® connector can be found on the side of the enclosure. The NMEA 2000®
NMEA 2000® network using a Maretron NMEA 2000® cable (or compatible cable) by
connecting the female end of the cable to the SIM100 (note the key on the male connector and
keyway on the female connector). Be sure the cable is connected securely and that the collar
on the cable connector is tightened firmly. Connect the other end of the cable (male) to the
NMEA 2000® network in the same manner. The SIM100 is designed such that you can plug or
unplug it from an NMEA 2000® network while the power to the network is connected or
disconnected. Please follow recommended practices for installing NMEA 2000® network
products.

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.

Before attempting to connect the SIM100 to the AC source, determine the type of system you
will be monitoring. The SIM100 supports the connection and monitoring of two different system
types; 1) switch with end-of-line resistor (Section 2.4.2.1), or 2) switch without end-of-line
resistor (Section 2.4.2.2). To connect Maretron SIM100 accessories, please refer to the
installation directions that accompany each accessory.

2.4.3 Checking Connections
Once the NMEA 2000® connection and switch connection(s) to the SIM100 have been
completed, check to see that information is being properly transmitted by observing an
“Troubleshooting”.
2.5 Configuring the SIM100
The SIM100 will transmit data over the NMEA 2000 network as it is shipped from the factory;
however, it may require configuration, depending on the type of switch monitored. There are
several configurable items within the SIM100, which are detailed in the remainder of this
section.
You configure the SIM100 using a Maretron DSM250 display or other NMEA 2000® display
unit that is capable of configuring the SIM100. Please refer to the Maretron DSM250 User’s
Manual for details.
2.5.1 Device Instance
NMEA 2000® provides a unique device instance for each switch monitoring device on a vessel.
This value should be programmed in each SIM100 so that each SIM100 is associated with a
unique device instance number. The default instance number is 0, which is used to indicate the
first SIM100 that is hooked to the network. Subsequent SIM100s connected to the network
would be numbered 1, 2, and so on.
2.5.2 Channel #1 Mode
2.5.3 Channel #2 Mode
2.5.4 Channel #3 Mode
2.5.5 Channel #4 Mode
2.5.6 Channel #5 Mode
2.5.7 Channel #6 Mode
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.
• 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.
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
information).

configured as “End of Line Resistor”. If the switch is closed, the
resistance should be close to 0 Ω.
