WARNING : The reference port uses the same connector configuration as the sensor.
If a reference switch or other device is accidentally connected to the RLE10 sensor
ports, the sensor network operation may become disrupted. This may cause errors on
the RCU10 system but no damage will be caused. Always ensure that nothing is
connected to the RLE10 sensor ports when not in use.
