Symptoms

While attempting to run WinDaq for your parallel port data acquisition device you encounter one of the following issues/messages:
The WinDaq title bar displays "DI-000 Acquisition" or "DI-??? Acquisition"
"Could not open data acquisition device"
"DI-500/720/730 series driver not installed"

Cause

This could be the result of one or more of the following:
   An incompatible parallel port cable
   The parallel port is not configured properly
   The PARPORT.SYS driver is not installed

Resolution

To resolve these issues follow the steps below.

Verify that you are using a compatible parallel cable

DATAQ Instruments parallel port products require the use of an IEEE 1284 parallel cable. If you are using a replacement (not provided with the unit), verify that "IEEE 1284" is printed on the cable.

Rerun the loader and try running WinDaq. Did WinDaq start properly? If not proceed to the next step.

Verify that your parallel port is configured properly

In order to communicate properly your parallel port must be in EPP or Bi-directional mode (the Standard printer port mode is supported by all -P suffix products). DATAQ Instruments parallel port products do not support ECP parallel port mode. The parallel port mode is set in the PC BIOS. Consult with your IT department to verify that your parallel port is configured as EPP or Bi-directional.

Rerun the loader and try running WinDaq. Did WinDaq start properly? If not proceed to the next step.

Verify that the PARPORT.SYS driver is installed

The PARPORT.SYS driver must be installed to run these products.

  4. Continue as prompted until installation is complete (don't leave the Epson LX-86 as the default printer)
  5. Reinstall WinDaq into the same folder and reboot the PC

Note: Once the loader and WinDaq are working the fictitious printer may be deleted.

If you continue to experience problems contact DATAQ support for further assistance.
