I am running the latest version of PClab2000se on Windows XP SP2, I also have tired older versions of PCLab2000se, deleting the .ini file every time. All with no luck.
The problem is when I start up the software and it tries to calibrate the scope but it can’t connect. It gives me the “no hardware response dialog”. If I click “run” it will read the scope but the values are completely incorrect because it never calibrated. The power LED is on and the LPT port is set correctly.
Another thing I have noticed is while trouble shooting I am hearing the internal relays, or whatever the “squeak” sound is, less and less. Now it doesn’t make any noise when trying to read it. It used to make noise right before displaying the cannot connect dialog, now it makes no noise.
I have tried reinstalling windows because I though it was a parallel port or driver issue. I also have tried it on another computer both with no luck.
I have also checked the power supply, it is 13V no load and 9v with load.
