Digital I/O Port Connector (CN8)
The board is equipped with an 8-channel (3 inputs and 5 outputs) digital I/O connector
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. The software application method is
provided in Appendix B.
