Data Acquisition Toolbox

Other Things to Try

If troubleshooting your hardware does not help you, then you might 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/Device Types and Full Adaptor Names

Vendor/Device Type	Full Adaptor Name
Agilent Technologies	mwhpe1432.dll
Measurement Computing	mwmcc.dll
Keithley	mwkeithley.dll
National Instruments	mwnidaq.dll
Parallel ports	mwparallel.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 might 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.
