Output current of TxD line and the leakage current through the protection diodes contribute to the voltage drop across the resistor R.
In too large output current in TxD circuit it is possible to get the peak output voltage of the barrier below 3.0V, which will cause incorrect
operation of the sensor. To be completely sure, that sensor will be powered properly, we recommend to check supply voltage using oscilloscope
while working with your device.
