The preset real time and preset live time are controlled by the. Processing this record causes the MCA spectra to be read. Writing 1 to this record copies the BaselineCutPercent from channel 1 to all channels. This means that all of the parameter setting that occurs during driver initialization and during iocInit when the records are initialized by EPICS is very fast because the values are not actually downloaded to the hardware. Note The Parport service is not listed in Computer Management and is inaccessible. This value is the average of the intantaneous dead time of all system channels.

In this case List mapping results in almost 7 times less data than MCA mapping, because most of the spectral channels are 0 in MCA spectra mode. This thread is locked. Make sure that you know how to restore the registry if a problem occurs.

The only significant difference is that in list mode there is no measure of live time at each “pixel”, and it will require more post-processing to arrange the data into spectra, if that is what is desired. The length of the baseline filter in samples.

Parallel Port Driver is not Supported in 64-bit Windows 7

Writing 1 to this record reads the low-level parameters for all channels. An error message that resembles the following may be logged in the System log on a Windows Vista-based or Windows Server based computer that does not have a parallel port: But it can sometimes be useful to read or even modify one of these low-level parameters.


Our header files are static or dynamic library 1. New Zealand – English.

Paralel was produced by reading the entire spectrum for 10×10 pixel region and then summing over all pixels, and then summing over all 7 detectors. The following records are defined in the database microDXP. You can follow the question or vote as helpful, but you cannot reply to this thread.

Dxp Error Failed To Load Parallel Port Driver

If very short acquisition times are fwiled used, and the SCA data are not actually required by the application, then setting NumSCAs to 1 will signficantly improve performance. To do this, follow these steps: Each SCA is defined by a low channel and a high channel. I make use of Altium Designer software.

Processing this record causes the MCA spectra to be read. The dynamic range of the ADC.

United Kingdom – English. Microsoft cannot guarantee that these problems can be solved. Data acquisition in mapping mode is very flexible. How do i check whether an I2C device works? When the driver initializes it queries the names of all of the low-level parameters, and makes these names available in stringin records.

The baseline histogram array. If this value is -1 then there is no preset number of pixels, and acquisition will continue forever until it is stopped manually with StopAll. Typically the user will only interact with the high-level parameters described above. These manuals all provide an excellent description of the theory of digital pulse processing as implemented in the DXP models from XIA.


If the time per pixel is relatively long then decreasing PixelsPerBuffer will result in more frequent updates of the MCA and statistics displays. As to why you are getting the error – there are paarllel possibilities.

DXP – EPICS software for XIA Digital Signal Processing Systems

Why I am getting this substrate picture, when i create a new workspace? If a future firmware version has more parameters than this, then a single constant in the driver will need to be increased, and more records will need to be added to dxpLowLevel. It extracts the Ni Ka peak channels to from the data. You should either install to a new directory, or completely remove the older version first.
