ADLINK PXI-3920/3910 Controller Installation and Configuration Guide

For example, routing the backplane trigger line 3 to the panel SMB：TRIG_Trigger_Route(PXI_TRIG_VAL_TRIG3, PXI_TRIG_VAL_SMB, PXI_TRIG_VAL_NONE);

Watch dog timer programming

The WDT driver provides the following functions (header file WDT. h):

InitWDT(): Initialize WDT.

SetWDT (second): Set timeout value. If second ≤ 255, the unit is seconds; If>255, the unit is minutes (actual value is second/60+1 minute).

StartWDT(): Start the countdown.

ResetWDT(): Reset the timer to its initial value and call it periodically before timeout.

StopWDT(): Stop the timer.

Typical process: InitWDT → SetWDT (10) → StartWDT, then execute ResetWDT in a loop. If the program freezes, the system will reset after 10 seconds.

Environmental reliability and maintenance tips

Working temperature: 0 ℃~55 ℃, it is necessary to ensure that the chassis has sufficient air cooling.

Non working vibration: 2.46 Grms (5~500Hz), working vibration: 0.5 Grms (with HDD), up to 6 Grms if using a solid-state drive.

Impact: 30G, half sine 11ms.

Due to CPU/memory soldering, it cannot be replaced by oneself. If you need to upgrade the memory, you can only expand it through the SO-DIMM slot.

If the system cannot start, you can try clearing CMOS (JP9) or check the priority setting of the startup device.

Common problems and troubleshooting

Problem Solution

Check if the DVI-I-VGA connector is secure when there is no display when powered on; If using LVDS output (such as 2558T-B), confirm that the Boot Display in BIOS is set to CRT+LVDS

Invalid USB keyboard/mouse. Use the included USB to PS/2 adapter cable or check if USB Keyboard Support is enabled in the BIOS

Unable to recognize hard drive, check SATA cable connection; Check if the hard drive is detected in BIOS; Try replacing the data cable or hard drive

CF card cannot be started. Confirm that the CF card is the boot medium and the format is correct; Check if the Hard Disk Boot Priority in BIOS is set to Ch0 M

GPIB devices are unable to communicate and install GPIB drivers; Check cable connections; Test basic communication using ADLINK GPIB Utility

Trigger signal without output, call TRIG_Trigger_Soute to set the correct route; Check SMB cable and terminal matching

System restart without reason to check if the watchdog unexpectedly starts (red LED lights up); If WDT is not used, ensure that the driver has been uninstalled or not activated

Not compatible with specific chassis, refer to the compatibility list; Confirm the signal definitions of P3/P5 on the backplane before installation, and avoid using non supported chassis (such as 2556T, etc.)
