Data Acquisition Toolbox

Other Things to Try

If troubleshooting your hardware does not help you, then you may need to register the hardware driver adaptor or contact The MathWorks for support.

Registering the Hardware Driver Adaptor

When you first create a device object, the associated hardware driver adaptor is automatically registered so that the data acquisition engine can make use of its services.

The hardware driver adaptors included with the toolbox are all located in the daq/private directory. The full name for each adaptor is shown below.

Table A-1: Supported Vendors and Full Adaptor Names

Vendor	Full Adaptor Name
National Instruments	mwnidaq.dll
ComputerBoards	mwcbi.dll
Agilent Technologies	mwhpe1432.dll
Windows sound cards	mwwinsound.dll

If for some reason, a toolbox adaptor is not automatically registered, then you need to register it manually using the daqregister function. For example, to manually register the sound card adaptor

daqregister('winsound');

If you are using a third-party adaptor, then you may need to register it manually. If so, you must supply the full pathname to daqregister. For example, to register the third-party adaptor myadaptor.dll

daqregister('D:/MATLABR12/toolbox/daq/myadaptors/myadaptor.dll')

Note    You must install the associated hardware driver before adaptor registration can occur.
