Digital I/O Connector (CN7)

This is a 5x2-pin (pitch=2.0mm) pin header. The board is equipped with an 8-channel (3
inputs and 5 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, see
Appendix B.
