Appendix B: How to use GPIO
Functional Description
GPIO signals are accessed via a 2.54mm 2x10-pin terminal block, including lsolated DI 8 bit,
DO 8 bit, DI Com, Power and GND.
DI/DO supports NPN (Sink) and PNPO (Source) mode.
DI mode is selected by external H/W connection. DO mode is selected by BIOS setting or
Application Program.
