Device Driver Handling in Windows
NT/2000/98/XP
2.1 NT 4.0 Device Driver
Driver Status
After finishing the installation and re-entering Windows NT, make sure the PCI device drivers are already started. For
PCIS-LVIEW to be able to communicate with NuDAQ PCI-bus card, device driver AdlDask as well as the card’s own
device driver (e.g. PCI6208, PCI7200, PCI7230, PCI7234, PCI7250, PCI7248, PCI7296, PCI7300, PCI7432, PCI7433,
PCI7434, PCI9111, PCI9112, PCI9113, PCI9114, PCI9118, or PCI9812, etc.) must be started. You can open the “Control
Panel”, double-click “Devices”, and a Devices window will be shown as below.
If the device status is none, you have to select the AdlDask, PCI6208, PCI7200, PCI7230, PCI7234, PCI7250, PCI7248,
PCI7296, PCI7300, PCI7432, PCI7433, PCI7434, PCI9111, PCI9112, PCI9113, PCI9114, PCI9118, or PCI9812 device
and press the “Start” button.
Note: The AdlDask driver must have been started as you press Start button to start the card’s own device driver.
Driver Utility
PCIS-LVIEW provides a utility, PCI Configuration utility (PciUtil). This utility is used to register new PCI drivers, remove
installed drivers and modify AI/AO/DI/DO continuous buffer of installed drivers. The allocated buffer sizes of AI, AO, DI,
DO represent the sizes of contiguous Initially Allocated memory for continuous analog input, analog output, digital input,
digital output respectively. Its unit is page KB, i.e. 1024 bytes. Device driver will try to allocate these sizes of memory at
system startup time. If this size of memory is not able to get, driver will allocate as much memory as system can provide.
The size of initially allocated memory is the maximum memory sizes that DMA or Interrupt transfer can be performed. It
will induce an unexpected result in that DMA or Interrupt transfer performed exceeds the initially allocated size.
The PCI Configuration utility is installed with PCIS-LVIEW setup program and located in <InstallDir>\Util directory.
Using this utility to install a new driver or set the size of continuous buffer, please refer to the chpater “NuDAQ PCI
Configuration Utility” in the NuDAQ PCI and NuIPC CompactPCI DAQ Cards Software Installation Guide.
