Digital I/O Connector (CN4)

This is a 2x5-pin (pitch=2.0mm) connector. The board is equipped with an 8-bit (4 inputs
and 4 outputs) digital I/O that meets requirements for a system customary automation
control. The digital I/O can be configured to control cash drawers and sense warning
signals from an Uninterrupted Power System (UPS), or perform store security control.
You may use software programming to control these digital signals, please refer to
Appendix B.
