ESD Precautions
Computer boards have integrated circuits sensitive to static electricity.
To prevent chipsets from electrostatic discharge damage, please ta ke
care of the following jobs with precautions:
Do not remove boards or integrated circuits from their anti-static
packaging until you are ready to install them.
Before holding the board or integrated circuit, touch an unpainted
portion of the system unit chassis for a few seconds. It
discharges static electricity from your body.
Wear a wrist-grounding strap, available from most electronic
component stores, when handling boards and components.

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. The digital I/O is controlled via software
programming. (The application method can be referred to Appendix B.)

CN7 is a PCI Express Mini Card connector with support for a PCI
Express x1 link and a USB 2.0 link. A PCI Express Mini Card can be
applied to either PCI Express or USB 2.0. The USB 2.0 support will be
helpful during the transition to PCI Express, because peripheral
vendors will need time to design their chipsets to have the PCI Express
function. During the transition, PCI Express Mini Cards can be quickly
implemented by using USB 2.0.

Digital I/O has 8bits (DIO0~7). Every bit can be pr ogrammed input or
output and is set pull-high with +5V level (main power)as default.
BIOS default is 3 IN 5 OUT. The d efault set all of input and output pin
to “1”.

;When M is FF, all DIO pins are high.(
Note1:
The N has 8bits. Every bit’s value is either “1” or “0”.
" 1" means that the bit is programmed to input.
" 0" means that the bit is programmed to output.
