ADLINK PXIe-9529H Dynamic Signal Acquisition Configuration Guide

Bank 0 (factory): read-only, stores factory calibration constants, write protection to prevent misoperation.

Bank 1 (user): readable and written, used to store on-site self calibration results.

By default, Bank 0 is loaded. If Auto Calibration is executed, the new constant is written to Bank 1, and Bank 1 can be loaded at the next startup specified by the software. This setting is stored in EEPROM and will not be lost upon power failure.

6.2 Self calibration execution standards

It is recommended to perform Auto Calibration in the following situations:

The module is installed for the first time on a new chassis.

The ambient temperature changes by more than ± 5 ° C.

Annual inspection or maintenance cycle.

Operation steps:

Preheat the module for at least 20 minutes after power on (ensuring stable internal temperature).

Disconnect all input signal cables (unloaded).

Call the driver API AutoCalibrate(), and the module automatically measures the internal reference voltage and corrects offset/gain errors.

After calibration is complete, set Bank 1 as the startup bank and restart the module.

Attention: Auto Calibration does not compensate for external sensor or cable errors, and the sensitivity deviation of the sensor itself needs to be corrected through software gain coefficients.

Software Ecology and Development Support

ADLINK provides multi-level software support for PXIe-9529H, all of which require the installation of MAPS Core basic package (including ACE device management tool, configurable DMA buffer size, device alias, and software panel for signal preview):

MAPS/C (C/C++): Includes header files, API libraries, and sample programs (including trigger configuration, multi card synchronization, data stream disk, etc.), suitable for high-performance custom development.

MAPS/LV (LabVIEW): Provides VI libraries and examples, supports graphical programming, and quickly builds test interfaces.

Driver and DMA: The module uses PCI Express Gen1 x4 interface, supports Scatter Gather DMA, can achieve large data transfer of non contiguous memory blocks, supports circular linked list buffer, suitable for long-term uninterrupted acquisition.

Environmental and Compliance Certification

EMC/EMI: Compliant with CE and FCC Class A standards (industrial environment). If used in residential areas, additional shielding measures may be required.

Temperature and reliability: Operating temperature range of 0-55 ℃, in compliance with PXI specifications. The module does not include user replaceable batteries, so there is no risk of battery replacement.

Overvoltage protection: differential input ± 42.4 V, pseudo differential positive terminal ± 42.4 V, negative terminal only ± 2.5 V (be sure to wire correctly to avoid damaging the front-end circuit).
