Tried this. Still no go. I think actually there is something more fundamental going wrong on my machine. I thought I would load up the latest version of PicoLog again and check that it worked OK (which I thought it seemed to before). When I ran the program and set the channels, the actual voltage reading was not showing the correct values. When I moved the sensor attached (a displacement transducer), I saw an apparent change (which I had previously thought was evidence of the installation working), but in fact the change was only a small change and not linear. I had moved the actual input voltage from -2 to about +2v, but the reading on the Logger was showing only about 100mV change. So it actually looks like noise. It looks like there could be other issues here, maybe with the parallel port. The port is on a PCI card made by ASIX and it uses their driver. Not sure if there are any issues with this card. To confirm, I am on Win 7 32 bit.
Any ideas ?
