Tried installing software V5.20.3 on my IBM Think Pad R50e running XP SP3. I coupled up ADC 200/100 and got error message on starting up PicoScope "ADC-200 not connected".
Noted Device Manager says LTP 1 uses resources 03BC - 03BE which some where I read was identified by Pico set up as LTP 3. So tried switching PicoScope to LTP 2 & 3 but no success. Also tried switching LTP port settings between options "Try not to use interrupt / Never use interrupt / use any interrupt assigned to..." but no success.
Just tried uninstalling the software and reinstalling. PicoScope About tool now states "ADC 200 Driver 4.86 Error 2 (HO SO)". (I did have Error 2 message previously but I can't now recall how I managed to get rid of it.)
I have tried software / hardware & leads on another PC and they work fine. Also LTP 1 port drives printer with no problem.
