ADLINK MXE-200 Fanless Embedded Industrial Control Computer Deployment Guide

The MXE-200 uses AMI Aptio BIOS (UEFI), press "Del" or "F2" to enter when booting up. Improper BIOS settings may result in inability to start. To restore default settings, you can solve the problem by clearing the CMOS (motherboard jumper or button battery short circuit).

3.1 Main Menu

System time/date: 24-hour format, in MM/DD/YY format.

System Management submenu: Provides SEMA board information, real-time temperature/fan speed, power consumption statistics, runtime statistics, and flag bits. The Power Up submenu includes:

Power Up Watchdog: If the dog is not fed within the preset time after power on, it will automatically reset, suitable for unmanned self starting scenarios.

ECO Mode: Reduce power consumption, but wait for at least 5 seconds after shutting down before restarting.

Power Up Mode: Optional options include Turn On, Remain Off, and Last State.

3.2 Advanced Menu Key Items

3.2.1 CPU Configuration

Limit CPUID Maximum: Windows XP needs to be set to Disabled, while Win7 and above default to Disabled.

Execute Disable Bit: It is recommended to enable and cooperate with supported operating systems to defend against buffer overflow attacks.

Intel Virtualization Technology: To run a virtual machine, set it to Enabled.

Power Technology: Enable power management features.

3.2.2 SATA Configuration

Serial ATA (SATA): Enable/disable SATA controller.

SATA Speed Support: Choose between Gen1 (1.5Gbps) or Gen2 (3Gbps) based on the mSATA disk specifications.

SATA Mode: AHCI is recommended to support NCQ and hot swapping; If installing an old OS (such as XP), IDE can be temporarily selected.

3.2.3 USB Configuration

Legacy USB Support: It is recommended to set it to Enabled to ensure that USB keyboard/mouse can be used under BIOS and DOS; If set to Auto, it will be automatically disabled when there are no USB devices.

XHCI Hand Off/EHCI Hand Off: It is recommended to enable both to be compatible with USB driver handover across different operating systems.

USB Mass Storage Driver Support：Enabled， Support booting of high-capacity storage devices such as USB drives.

USB Host Controller Configuration: It can control the enable/disable of each USB port (0-3) separately, facilitating the isolation of faulty ports.

3.2.4 Serial port mode configuration (Super IO/ACPI related)

The COM2 (serial port 2) of MXE-200 supports RS-232/422/485 mode switching, which is set through BIOS instead of jumper. Under the "Advanced" menu, find the "HSUART Port Mode" or similar item ("LPSS HSUART # Support" in the manual), and configure each HSUART port separately as RS-232, RS-422, or RS-485. It is recommended to confirm the equipment protocol and set it correctly before connecting the PLC, smart instrument or frequency converter in practice.

3.2.5 Network Configuration

Network Stack: If you need to boot from the network (via PCIe or UEFI HTTP), set it to Enabled.

The onboard dual Intel I210IT GbE controller supports advanced features such as IEEE 1588 time synchronization, LAN Teaming, WOL, Jumbo Frame, etc., and can enable/disable PXE ROM in BIOS.

3.2.6 ACPI Setting

Enable Hibernation: If sleep function (S4) is required, set it to Enabled.

ACPI Sleep State: S3 (Suspend to RAM) or S1 can be selected.

3.2.7 Thermal Configuration

MXE-200 supports ACPI thermal management:

Critical Trip Point: System shutdown temperature threshold (if exceeded, the OS will execute an emergency shutdown).

Passive Trip Point: The temperature at which the processor begins to downshift and throttle.

Active Cooling Trip Point: Active cooling (fan) startup temperature (if an external fan is connected).

3.2.8 Security Configuration

TXE (Intel Trusted Execution Engine): It is recommended to keep it enabled.

TXE Firmware Update: To update the TXE firmware, set it to Enabled.

3.2.9 Miscellaneous Configuration

OS Selection: Select Windows or Linux to optimize resource allocation.

3.3 Security Menu

Administrator Password and User Password can be set. If only an administrator password is set, a password is required to enter BIOS; If only a user password is set, a password is required for both booting and entering the BIOS. Forgot password requires clearing CMOS.

3.4 Boot Menu

Setup Prompt Timeout: Set the number of seconds to wait for the hotkey to be pressed.

Quiet Boot: If enabled, display OEM logo; if disabled, display POST self-test information.

Fast Boot: Enable skip some initialization to accelerate startup.

Boot Option priorities: Adjust the boot device order, support UEFI and Legacy modes, switchable in CSM Configuration.

CSM Support: To boot from a traditional MBR disk, CSM needs to be enabled.

3.5 Exit menu

Provide options such as save/discard modifications, restore defaults (Fail Safe), and save as user defaults. If the system cannot start due to incorrect settings, it can be restored to the factory's optimal value through Restore Defaults (non performance limit, but stability takes priority).

Chapter 4: Watchdog Timer (WDT) and DI/O Programming Practice

The watchdog and digital I/O functions provided by MXE-200 are key to achieving unmanned self recovery and peripheral control. The official provides API libraries based on Windows (Matrix_wdt. h/Matrix_wdt. lib, Matrix_dio. h/Matrix_dio. lib).
