ESD Precautions
Computer boards have integrated circuits sensitive to static electricity. To prevent chipsets
from electrostatic discharge damage, please take 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.

Internal Buzzer
Pin 1(-) and 2(+) connect the internal buzzer cable.
Power Status (PS-ON)
Pin 4 and pin 3 are PS-ON signal which are connected to know the power status of this
board.
Power LED
Pin 6 connects anode (+) of LED and pin 5 connects cathode (-) of LED. The power LED
lights up when the system is powered on.
Power On/Off Button
Pin 8 and 7 connect the power button on front panel to CPU board, which allows users to
turn on or off power.
System Reset Switch
Pin 10 and 9 connect the case-mounted reset switch that reboots your computer without
turning off the power switch. It is a better way to reboot your system for a longer life of
system power supply.
HDD Activity LED
This connection is linked to hard drive activity LED on the control panel. LED flashes
when HDD is being accessed. Pin 12 and 11 connect the hard disk drive to the front
panel HDD LED, pin 11 is assigned as cathode(-) and pin 12 is assigned as anode(+).
2.5.2 USB 2.0 Wafer Connector (CN5)
This is a 2x5-pin (pitch=2mm) wafer connector, which is compliant with Hirose
DF11-XDP-2DSA, for installing versatile USB 2.0 compliant interface peripherals.

2.5.3 SIM Card Wafer Connector (CN7)
The CN7 is a 6-pin (pitch=1.0mm) wafer connector, which is compliant with JST
B6B-PH-K-S, for SIM Card interface. AX93A19 is suggested to use for CN7 to have SIM
card slot.
In order to work properly, the SIM card must be used together with 3G/4G LTE module in
M.2 Key B connector/CN10. It is mainly used in 3G/4G LTE cellular network application.
2.5.4 Digital I/O Connector (CN8)
This is a 2x5-pin (pitch=2.0mm) connector. The board is equipped with an 8-bit 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.
