Ordering Configuration

The list that follows includes important information that you need to purchase an Advantech PC:

  • Aerotech recommends that you order Windows 10 Enterprise LTSC 2021 (not Windows 10 Professional) so that you have more control over automatic updates. Windows 11 is not supported on this platform.

  • Windows must be installed in Legacy boot mode (EFI booting is not supported for real-time performance). Make sure Arrow or Advantech knows this requirement when you order.

  • You can select a different amount of RAM. But, make sure that you order two RAM sticks so that you can use dual channel memory.

  • You can customize the size of your SSD.

  • Integrated Intel UHD Graphics has better real-time performance than a dedicated graphics card.

Aerotech used the configuration in the table that follows when testing the AIMB-785 and AIMB-275 PCs.

Required Custom Configuration

AIMB-275G2-00A2E Configuration (Mini-ITX)

You must update the factory shipped BIOS. See the instructions that follow.

  1. Download AIMB-275.zip.

  2. Extract the files.

  3. Open How to flash the BIOS.pdf and use the instructions to update the BIOS.

  4. Change the BIOS settings to be the same as in BIOS Settings for AIMB-275.

AIMB-785G2-00A2U Configuration (ATX)

You must update the factory shipped BIOS. See the instructions that follow.

  1. Download AIMB-785.zip.

  2. Extract the files.

  3. Open How to flash the BIOS.pdf and use the instructions to update the BIOS.

  4. Change the BIOS settings to be the same as in BIOS Settings for AIMB-785.

Other Settings

  • VGA / Video Monitor operation: The AIMB-785G2-00A2U BIOS always shows that a VGA monitor is connected. This lets Windows operate without a monitor connected. If the user connects a single (DVI) monitor, the BIOS reports to Windows that a second, VGA monitor is connected. The user must mirror the Windows desktop to both monitors or configure Windows to use the DVI monitor as the primary display.

  • SATA port: Connect SATA devices to the red SATA0 or SATA1 port connectors only. Do not connect SATA devices to the blue ports. This causes problems with the real-time performance of the controller. Do not connect RAID storage devices. They are not permitted.
