4.6.2 Jumper J2
All pins 1 of jumper J2 are connected to +3V3 supply voltage, and all pins 3 of
jumper J2 are connected to GND. When using the GPIOs or AIOs as inputs, this
arrangement allows to place jumpers in position 1-2 to generate a HIGH and to
place jumpers in position 2-3 to generate a LOW input. When using the GPIOs or
AIOs as outputs, pin 2 will be used to access the signal.
