Hardware Installation Guide

2.1 Anti static specifications for unboxing

Before disassembly, completely disconnect the power supply and wear an anti-static wristband;

Do not place the motherboard on the carpet, and only pinch the edges of the accessories;

Do not plug or unplug any boards/cables when the motherboard is powered on during standby.

2.2 motherboard chassis fixation

Standard ATX screw hole position, screws should be tightened moderately to avoid fracturing the PCB board layer.

2.3 Key points for installing DDR3 memory

Dual channels must be paired with the same capacity, frequency, and brand of memory; Single channel only;

DDR2/DDR cannot be mixed, and notch protection prohibits violent insertion;

Disassembly and assembly: Open the two end buckles outward and insert them vertically until the buckles automatically lock.

2.4 Expansion Card Installation (PCIe/PCI)

PCIe x16 is used for independent graphics cards, PCIe x4 is compatible with acquisition cards and network cards; 4 PCI compatible with traditional industrial peripherals;

Turn off the power and remove the chassis cover. Press the card vertically until it fits completely, and fix it with screws.

2.5 Definition of Three Main Function Jumpers

CLCMOS (Clear CMOS)

Power off and unplug the battery, short the jumper 1-2 (normal) for 2-3 5-10 seconds, restore the factory BIOS, and then restore the jumper.

PSON1 (AT/ATX power switch)

Default 2-3=ATX (power on button); 1-2=AT (automatic power on).

JGPIO-PWR1 (GPIO power supply selection)

Default 2-3=5V; 1-2=12V, providing power to the 4-in-4-out GPIO module.

2.6 Complete description of all onboard built-in pins
