OS/X, can confirm my 8/8/8 with a 1103 on channel 0 works via the native os/x application.

If I download the sample VoltageRationInputExample and configure it to listen to the sensor WITHOUT setting the sensor type, I get readings from 0 to 1 that vary as I move my hand up/down in front of the sensor. If on the other hand I set the sensorType to PN_1103, then I no longer get readings. Here's the code without setting the sensorType:

If I try moving the "setSensorType" to before the open, I get an error that says the channel is not attached.

If you set the sensor type, you will get SensorChange events not VoltageRatioChange events - looks like the example is missing code to set up a Sensor Change event.
