During the installation process, when the system recognizes the NVMe SSD, it is necessary to load the Intel RST driver (if not built-in), which can be downloaded from the ADLINK product page.

After completing the system installation, install the following drivers in sequence (all downloaded from the ADLINK product page):

Intel chipset driver

Intel graphics driver

Intel Ethernet driver (I225/I210)

Intel RST driver (storage)

Intel ME driver

GPIB driver (compatible with NI-488.2)

PXI Trigger I/O driver (used to trigger routing)

PXI Platform Service (for chassis monitoring and resource management)

The driver installation package is usually Setup. exe, follow the prompts to complete it.

Note: The USB 3.0 interface may not be supported in the OS installation environment. Please use the USB 2.0 port to connect the installation media.

Trigger I/O programming and routing configuration

The front panel SMB trigger connector (TRIG I/O) can be programmed to achieve bidirectional routing between external trigger signals and PXI trigger buses, while supporting software trigger signal output. The driver provides an API function library (included in the PXI Trigger I/O driver), which can be found in the file X:  ADLINK  PXI Trigger IO  Include  pixtrigio. h.

5.1 Initialization and Shutdown

TRIG_Init(): It must be called first to initialize and trigger the I/O function.

TRIG_Close(): Called before exiting the application to release resources.

5.2 Software triggered generation

TRIG_SETSoftTrg (U8 status): Set the logic level (0 low/1 high) of the SMB pin or trigger bus to generate software trigger pulses.

5.3 Triggering Routing Settings

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

Source: Trigger source, optional PXI_TRIG_VAL_SMB (SMB), PXI_TRIG_VAL_SOFT (software), PXI_TRIG_VAL_TRIG0~7 (bus lines 0~7).

Dest: Target, as above (excluding SOFT).

Halfway: Only when the source is SOFT and the dest is SMB, it is necessary to specify which trigger bus to pass through as the intermediate path (such as PXI_TRIG_VAL_TRIG0), and set it as PXI_TRIG_VALSinoNE in other cases.

For example, routing SMB input triggers to PXI trigger bus 5:

TRIG_Trigger_Route(PXI_TRIG_VAL_SMB, PXI_TRIG_VAL_TRIG5, PXI_TRIG_VAL_NONE);

For example, software triggers output to SMB via bus 3:

TRIG_Trigger_Route(PXI_TRIG_VAL_SOFT, PXI_TRIG_VAL_SMB, PXI_TRIG_VAL_TRIG3);

5.4 Querying and Clearing

TRIG_Trigger_Soute_Query(): Get the current routing settings.

TRIG_Trigger_Clear(): Clears all routing paths.

5.5 Obtain Driver Version

TRIG_dDriverRevision(): Returns the major version number and two minor version numbers.

Common maintenance and troubleshooting

6.1 Replacing Solid State Drives (SSDs)

The controller reserves a SATA 3.0 interface for 2.5-inch SSD expansion. Installation steps:

Shut down and remove the controller, observe the anti-static measures.

Unscrew the five screws that secure the hard drive bracket and remove the bracket.

Remove the four fixing screws on both sides of the SSD, take out the old disk, and replace it with a new one.

Reverse the installation back to the bracket and reinstall the controller.

6.2 Replacing CMOS batteries

When the system time is lost or BIOS settings cannot be saved, the CR2032 lithium button battery needs to be replaced:

Shut down and remove the controller.

Find the battery holder on the front of the board (see "Onboard Connections" diagram), and carefully pry up the battery with a small flat head screwdriver (from the negative buckle side).

Insert the new battery with the positive pole (+) facing upwards, first clip it into the positive side, then press down on the negative side, and hear a click to place it in place.

Reinstall the controller and reset the BIOS time.

6.3 Clear CMOS (Restore BIOS Default)

If the system fails to start or BIOS settings cause a malfunction, the CMOS can be cleared:

Shut down and remove the controller.

Find the clear CMOS switch (SW1) on the board, turn it from the Normal position to the Clear position, wait for 5 seconds, and then turn it back to Normal.

Reinstall the controller, press Delete to enter BIOS upon startup, press F9 to load optimized default values, and press F10 to save and exit.

6.4 Dual BIOS Automatic Recovery

The controller is equipped with dual BIOS (main BIOS+backup BIOS) and an independent monitoring chip. If the main BIOS fails to update or is damaged, causing abnormal startup, the monitoring chip will automatically activate the backup BIOS to complete the startup and prompt that the backup BIOS has been enabled when booting up. At this point, it is necessary to contact technical support to restore the main BIOS function (usually requiring re burning).

6.5 Common startup troubleshooting

System no display: Confirm that the DisplayPort cable is securely connected and whether the monitor supports the current resolution; Try switching to DVI/HDMI.

Unable to recognize peripheral: Check if USB Legacy Support is turned on. If you need to boot from USB, ensure that the USB device boot option in CSM is correct.

Network connection failure: Check the status of the dual port LED - Active/Link yellow light constantly on indicates connection, flashing indicates transmission; Speed green light is 100M/1G, orange light is 2.5G (3988TL). If it is not lit, check the network cable and switch configuration.

GPIB communication exception: Confirm the use of a dedicated GPIB cable (such as ACL-IEEE488-MD1-A), install NI-488.2 compatible drivers, and check the GPIB address settings.

Maintenance suggestions and environmental requirements

Cooling: The controller adopts passive cooling (relying on the chassis fan) to ensure smooth airflow near the chassis system slot and unobstructed air inlet.

Cleaning: Regularly clean the front panel interface and ventilation holes with an anti-static soft brush.

Power supply: The controller has high power consumption (up to 6A under+12V overload). Please confirm that the PXIe chassis has sufficient power supply, especially when multiple high-power peripheral modules are installed simultaneously.
