Product Usage Instructions

Volatile Memory:

The volatile memory in the PCI-6731 is a type of FPGA memory with a size of Xilinx XC2S100. It does not have battery backup and is not user-accessible. However, it is system-accessible. To sanitize the volatile memory, you need to cycle power by completely removing power from the device and allowing for adequate discharge. This process requires a complete shutdown of the PC and/or chassis containing the device. A reboot is not sufficient for the completion of this process.

Non-Volatile Memory (incl. Media Storage)

The non-volatile memory in the PCI-6731 is an EEPROM with different sizes for different types of information. The device configuration is stored in 8 kB, while calibration information, calibration metadata, and calibration data2 are stored in 512 B. The non-volatile memory does not have battery backup and is not user-accessible. However, it is system-accessible. There is no specific sanitization procedure for the non-volatile memory. To clear the calibration metadata area of the non-volatile memory, follow these steps:

Use the NI DAQmx API to clear the user-accessible areas of the Calibration Information EEPROM. For instructions, visit www.ni.com/info and enter info code DAQmxLOV.

Procedures

Procedure 1 – Board Assembly Part Number identification:
To determine the Board Assembly Part Number and Revision, refer to the “P/N” label applied to the surface of your product as shown below. The Assembly Part Number should be formatted as “P/N: ######a-vvL” where “a” is the letter revision of the Board Assembly (eg. A, B, C…) and the “vv” is the type identifier. If the product is RoHS compliant, “L” can be found at the end of the part number.

Procedure 2 – Calibration Information EEPROM (Calibration Metadata):
The user-accessible areas of the Calibration Information EEPROM are exposed through a calibration Applications Programming Interface (API) in LabVIEW. To clear the calibration metadata area, complete the following steps:

The user-accessible areas of the Calibration Information EEPROM can be cleared using the NI DAQmxAPI. For instructions on how to clear these areas, go to www.ni.com/info and enter info code DAQmxLOV

Terms and Definitions

Cycle Power:
The process of completely removing power from the device and its components and allowing for adequate discharge. This process includes a complete shutdown of the PC and/or chassis containing the device; a reboot is not sufficient for the completion of this process.
Volatile Memory:
Requires power to maintain the stored information. When power is removed from this memory, its contents are lost. This type of memory typically contains application-specific data such as capture waveforms.
Non-Volatile Memory:
Power is not required to maintain the stored information. The device retains its contents when power is removed. This type of memory typically contains the information necessary to boot, configure, or calibrate the product or may include device power-up states.
User Accessible:
The component is read and/or write addressable such that a user can store arbitrary information about the component from the host using a publicly distributed NI tool, such as a Driver API, the System Configuration API, or MAX.
System Accessible:
The component is read and/or written addressable from the host without the need to physically alter the product.
Clearing:
Per NIST Special Publication 800-88 Revision 1, “clearing” is a logical technique to sanitize data in all User Accessible storage locations for protection against simple non-invasive data recovery techniques using the same interface available to the user; typically applied through the standard read and write commands to the storage device.
Sanitization:
Per NIST Special Publication 800-88 Revision 1, “sanitization” is a process to render access to “Target Data” on the media infeasible for a given level of effort. In this document, clearing is the degree of sanitization described.
