Data Acquisition Toolbox

Examining Your Hardware Resources

You can examine the data acquisition hardware resources visible to the toolbox with the daqhwinfo function. Hardware resources include installed boards, hardware drivers, and adaptors. The information returned by daqhwinfo depends on the supplied arguments, and is divided into these three categories:

• General toolbox information
• Adaptor-specific information
• Device object information

If you configure hardware parameters using a vendor tool such as National Instruments' Measurement and Automation Explorer or ComputerBoards' InstaCal, then daqhwinfo will return this configuration information. For example, if you configure your ComputerBoards device for 16 single-ended channels using InstaCal, then daqhwinfo returns this hardware configuration. However, the toolbox does not preserve configuration information that is not directly associated with your hardware. For example, channel name information is not preserved. Refer to Appendix A, "Troubleshooting Your Hardware" for more information about using vendor tools.
