6.1 xTPrs Configuration Options
The default configuration of the xTPrs sensor interface input is current sinking which
supports PNP (current sourcing) type sensors.
This interface can be reconfigured to support NPN (current sinking) type sensors by
modifying a PCB component installation.
To change the configuration to NPN Sensor, remove R100 and install a 0402, zero ohm
resistor at R87.
