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.
• MS-1075 Magnetic Switch Recessed (Indoor/Outdoor) 1.4 Quick Install Installing the Maretron SIM100 involves the following five steps. Please refer to the individual sections for additional details. 1. Unpack the box (Section 2.1) 2. Choose a mounting location (Section 2.2) 3.
® ® 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.
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.
® ® 2.4.2.1 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.
® 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.
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.
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).
® ® 5 Technical Specifications As Maretron is constantly improving its products, all specifications are subject to change without notice. Maretron products are designed to be accurate and reliable; however, they should be used only as aids to navigation and not as a replacement for traditional navigation aids and techniques.
® ® 7 Installation Template Please check the dimensions before using the following diagram as a template for drilling the mounting holes because the printing process may have distorted the dimensions. Figure 5 – Mounting Surface Template Revision 1.2 Page 11...
