Dr DAQ connection to a presario Compaq laptop

Bought a DrDAQ that arrived today. I have installed the drivers and the updated drivers from your website and get the error:Driver v3.2 pico.sys not found.

Any clues?

If the program appears to not find the unit then try selecting all the available LPT ports. Try LPT1, LPT2 and LPT3 to see if any of these give readings. This is because Windows can virtualise the parallel port and it could be going by a different number.

If this doesn't help, then check and make sure that nothing else is installed to the parallel port. Printers, scanners and zip drives can all cause driver conflicts. If there is anything installed try assigning it to a different port or uninstalling it and see if this helps.

Also check the parallel port settings in the BIOS of the computer. It should be set to one of the following modes:

SPP, Normal, Output Only, Unidirectional

It should not be set to ECP, EPP or Bidirectional.

If none of this helps then please do not hesitate to contact me further.
