Introduction 
The Maretron 10271 is an accessory for the SIM100 Switch Indicator Module. The 10271 has a set of normally 
closed contacts that will open whenever a flow of cooling water of a user-settable amount is detected.  
 
Instructions 
Please follow these instructions to connect the 10271 to the NMEA 2000 network via a Maretron SIM100 Switch 
Indicator Module. The wiring diagram appears in Figure 1. The diagram shows a connection to channel #1, but 
connections to other channels are similar. Please refer to the original manufacturer’s instructions packaged with 
the product for additional details including setting of the switch activation flow rate. 
 

 

1.  Install the two wires from the 10271 to a free switch channel on the SIM100. The two wires are 

interchangeable. The example in Figure 1 shows the flow switch connected to switch channel 1, terminals 
SW1A and SW1B.  

 

2.  Use a Maretron DSM250 display (firmware 1.3.5 or higher), or the DSM250 Viewing function of Maretron 

N2KAnalyzer software, or other Maretron display product capable of configuring the SIM100 to set the 
switch channel mode (indicated as “Channel #x Mode” on the DSM250) for the appropriate channel to the 
“No End of Line Resistor” setting. For this example, you would set “Channel #1 Mode” to “No End of Line 
Resistor”. 

 

3.  Supply Power to the NMEA 2000 network, Verify that the switch channel indicates an “on” (normal) state 

using Maretron N2KView software, N2KAnalyzer, or other product capable of displaying switch indicator 
state. 

 

4.  Start cooling water flow through the 10271 and verify that the switch channel indicates an “off” state.
