ADLINK PXIe-3987/3977/3937 Deployment and Debugging

SATA Controller: enabled by default, can be temporarily disabled if using external USB boot.

SATA Signal Setting: It is necessary to choose "HDD" or "SSD" according to the actual storage medium, which affects the signal balance parameters.

3.3 TPM 2.0 and Secure Boot (New Important Features)

In [Advanced] → [TPM 2.0 Configuration]:

Security Device Support: Set to "Enable" to activate TPM.

SHA-256 PCR Bank: It is recommended to enable it to comply with the security requirements of Windows 11 and higher versions.

TPM2.0 UEFI Spec Version: If installing Windows 10, select "TCG_1_2" compatibility mode; If it is Windows 11, select "TCG_2".

Secure Boot (located in the [Security] menu): Before setting "Attempt Secure Boot" to "Enabled", it is necessary to ensure that the system has installed a UEFI boot OS (GPT partition), otherwise it will result in inability to boot. After activation, it can prevent unsigned driver loading and enhance industrial control security.

3.4 Detailed steps for switching boot mode (Legacy vs UEFI)

For old DOS or specific RTOS, it is necessary to switch to Legacy mode:

[Boot] → [Boot Configuration] → Boot Mode Select "Legacy".

[Boot] → [CSM] → Set CSM Support to "Enabled".

Set the OpROM execution strategy for Network, Storage, Video, and Other PCI Devices to 'Legacy only'.

Press F10 to save and exit.

To restore UEFI, simply select "UEFI" in Boot Mode Select and load the optimized default values (F9).

3.5 System Health Monitoring

In [Advanced] → [Hardware Health Configuration], real-time reading of:

PCIe switch environment temperature and core temperature

System+3.3V,+5V,+12V and battery voltage

This data is extremely useful for verifying the heat dissipation design of the chassis.

PXI triggers I/O programming library (detailed explanation of functional functions)

This series shares the same set of trigger APIs, located at X:  ADLINK  PXI Trigger IO  Include  pixtrigio. h. The following is a practical explanation of key functions.

4.1 Initialization and Resource Management

TRIG_Init(): Must be called first, returns ERR_CoError to indicate success.

TRIG_Close(): Called before the application exits to release interrupts and memory resources.

4.2 Software triggering and status reading

TRIG_SETSoftTrg (U8 Status): Generate TTL level (0 or 1), which can be output to the SMB port or backplane trigger line.

TRIG_Gets SoftTrg (U8 * Status): Read the current software trigger value (default low level).

4.3 Routing Configuration Function (Core)

TRIG_Trigger_Route(U32 source, U32 dest, U32 halfway)：

Parameter description:

Source: Signal source, optional PXI_TRIG_VAL_SMB (external input), PXI_TRIG_VAL_SOFT (software), PXI_TRIG_VAL_TRIG0~7 (backplane cable).

Dest: Destination, within the same range as above (excluding SOFT).

Halfway: Only when source=SOFT and dest=SMB, a trigger line needs to be specified as the intermediate node, and in other cases, it is set as PXI_TRIG_VALINONE.

Typical use case:

External trigger synchronous multi board: Route SMB input to backplane TRIG0 → source=SMB, dest=TRIG0, halfway=NONE.

Software triggers output to the backplane: source=SOFT, dest=TRIG1, halfway=NONE.

Software triggers output to SMB (intermediate required): source=SOFT, dest=SMB, halfway=TRIG2 (select any idle trigger line).

4.4 Routing Query and Clearing

TRIG_Trigger_Soute_Query(): Returns the current source/dest/halfway value for debugging purposes.

TRIG_Trigger_Clear(): Reset all routes to default state.

4.5 Driver version acquisition

TRIG_dDriverRevision() returns the major and minor version numbers for compatibility verification.

Dual BIOS automatic fault recovery mechanism

This series retains a dual BIOS design, including a main BIOS and a backup BIOS, managed by independent hardware monitors.

Working principle: During normal startup, the main BIOS boots. If the startup timeout is caused by upgrade interruption or verification failure, the monitor automatically switches to the backup BIOS and prompts "Backup BIOS deployed".

On site handling: When this prompt appears, the system can still work normally, but it is necessary to contact technical support as soon as possible to refresh the main BIOS. During the waiting period for recovery, it is recommended to save the current configuration (which can be done through the BIOS's' Save as User Defaults').

Preventive measures: When updating BIOS, be sure to ensure stable power supply and do not cut off power midway.

Driver Installation and Software Ecology (Windows 10 64 bit)

In addition to the built-in drivers in Windows 10, the following components must be manually installed (downloaded from the corresponding product page on the ADLINK official website):

Intel Chipset Driver

Intel Graphics Driver

Intel Ethernet/LAN Driver（I219 & I210）

Intel ME（Management Engine）Driver

Intel RST（Rapid Storage Technology）Driver

GPIB Driver (compatible with NI-488.2 API)

PXI Trigger I/O Driver (providing the above API library)

PXI Platform Services (for chassis identification and resource management)

Optional installation of MAPS Core software suite for advanced measurement automation applications. Suggested installation sequence: chipset → graphics card → network card → ME → RST → trigger driver → GPIB → platform service.
