CONFIGURATION

Digital I/O Configuration

Introduction The PHU’s Digital I/O port includes a total of 7
input/output pins and one ground pin. These 7
pins can be individually configured as either
inputs or outputs based on user settings. By
default, these 7 pins are set to a static voltage of 5V
output. When configured as inputs, the pins can
be triggered by shorting them to ground. When
configured as outputs, the voltage level of each
pin will be either 5V or 0V (relative to ground),
depending on the PHU’s status. Additionally, the
polarity (positive or negative) of these 7 pins can
be adjusted through configuration settings.
