Product Usage Instructions
- Connect the panel power by setting the PNL_PWR1 jumper to the desired voltage level (1-2 for +3V, 2-3 for +5V).
- Adjust the backlight volume by using the BLT_VOL1 jumper, which has various control signals.
- Connect a speaker to the SPEAKER1 header. The pin configuration for the speaker is as follows:
Pin Signal Name 1 SPK L- 2 SPK L+ 3 SPK R+ 4 SPK R- - Connect a CPU fan to the CPU_FAN1 connector, which provides +12V power.
- Connect SATA devices by using the SATA_PWR1 connector for power and the SATA3_0 connector for data.
- Connect a MIPI device to the MIPI1 connector, which has various signal pins for data transmission.
- Install DDR4 memory modules into the DDR4_A1 slot (supports DDR4 only).
- Connect a VGA display to the VGA1 connector.
- Connect front panel audio devices to the HD_AUDIO1 header, which has various signal pins for audio input and output.
- Adjust the voltage level for backlight power control by setting the BLT_PWM2 jumper to 1-2 for 3V level (

Installation of ROM Socket
- Do not apply force to the actuator cover after ic inserted.
- Do not apply force to actuator cover when it is opening over 120 degree, Otherwise, the actuator cover may be broken.
- The yellow dot (Pin1) on the ROM must be installed at pin1 position of the socket (white arrow area).
- Make sure the white dot on the ROM is installed outwards of the socket.
- For further details of how to install ROM, please refer to ASRI website.
Warning: If the installation does not follow as the picture, then it may cause severe damage to chipset & MB.
