Note: The GPIO settings can be turned on optionally by hardware or software, as illustrated
below.
By hardware, push the GPIO switches to the left.
By software, use the IndyTool to turn on the GPIO settings. The General purpose GPIO can be
configured as Input or Ouptut and the corresponding state is also reflected. The Refresh button
can be used to update the states of the GPIOs configured as input. The greyed state boxes
reflect the Input State. When configured as GPOs the state becomes user selectable.
The ARM GPOs can be set Low and High via the ARM GPO control box.
