3. Optical Sensor the Flight Car or Boat Data Recorder The sensor plugs into your Data Recorder as shown in Figure 1 Make sure that you connect it in the correct location on the recorder and with the correct polarity the plug is polarized Extra Pin White Red Connecting the Sensor to the eLogger V3 The Sensor plugs into the RPM port of the eLogger V3 as shown in Figure 2A Figure 2 Connecting the 4 Wire Optical Sensor to the MicroPower V1 or MicroPower V2 The 4 Wire Optical sensor plugs into your MicroPower V1 or V2 as shown in Figure 2 Make sure that you connect it in the correct location on the MicroPower and with the correct polarity Note that if you use a temperature sensor along with the Optical sensor the pin on the optical sensor s loose wire can be snapped into the spare slot in the temperature sensor s connector Alternatively you can spin the temperature sensor around so that the two wires are reversed and the spare slot is hanging out over the edge of the MicroPower it is ok to reverse the polarity of the temperature sensor If the temperature sensor is not being used the pin on the loose wire connects by itself to the pin on the MicroPower as shown and the loose piece of heat shrink should be slid down to insulate the pin Connecting the 3 Wire Optical Sensor to the MicroPower V2 If you have the MicroPower V2 large V2 appears in white letters on the underside of the circuit board near t
