Warmly remind:
(1) By default,the motherboard supports EDP1,EDP2 pins,does not support LVDS pin.
The EDP2 conflicts with LVDS.You can choose one of the EDP2,LVDS,but not both.If you need LVDS,please tell us to
change the motherboard in advance.
(2)
EDP1 is 30pins,it uses an integrated screen&backlight cable;
EDP2 is 20pins,it uses independent screen cable,backlight cable.
(3) The motherboard supports optional 2*COM,4*COM.By default,the COM1,COM2,COM3,COM4 only support RS232.
(4) The 9th pin of COM1/COM2/COM3/COM4 supports output optional 0V , 5V ,12V by JPCOM1/JPCOM2/JPCOM3
/JPCOM4 jumper setting.
By default,the COM1,COM2 have 0V.
(5) The motherboard only has 1*USB3.0 port.In the blue USB interface,the above is the USB2.0 interface,and the
bottom is the USB3.0 interface.The black USB interfaces are USB2.0 ports.
(6) By default,the Mini-PCIE slot has PCIE,USB signals.
(7) By default,the MSATA slot has SATA,USB signals.The MSATA slot supports changing the SATA signal to the PCIE
signal.Please note that the SATA signal will not exist after the change.If you need PCIE signal for MSATA slot,please
tell us in advance.
(8) By default,the motherboard is fanless,if you need fan cooling,please contact us to change in advance.
(9) The motherboard only supports 1*RJ45 LAN port,does not support 2*LAN,POE port.

2.0 The 1st pin identification methods:
(1) Method 1: Look at the silkscreen mark next to the front pin of the motherboard.
Will be represented by a triangle symbol or a bold line or "1";
(2) Method 2: Look at the back pad of the motherboard. The square pad is the first pin;
Please pay attention to distinguish the 1st pin when plugging in the device and the cable, otherwise the motherboard
and device will be damaged.

2.14 Motherboard discharges,clears and battery:
The"CMOS" is powered by the button battery on the motherboard.
Clearing the "CMOS" will cause the previous BIOS settings to be cleared and restore the original factory setting.
Clearing CMOS procedures:
Method 1:
(1)Turn off the motherboard and disconnect the power.
(2)Use metal conductors to briefly connect the pin 2,pin 3 of "CLR_CMOS1" for 5~6 seconds.
(3)When booting up, press "Delete" to enter the BIOS.
(4)After entering the BIOS, press "F9" ,"Enter" to reload the optimal default value.
(5)Press the "F10" to save and exit the setting.
Method 2:
When the motherboard is powered off, plug and pull the button battery to achieve the motherboard clear function.
Remove the button battery, and then re-install the button battery after 10 seconds.Please pay attention to the positive
and negative of the battery.
