Non working PCS500

I have a PCS500 ser# 200613859. I dont know how old this device is but it was on sale marked down to 68 dollars so that tells me something, like they were being dumped or something like that.
I have read through your forums and found that this device works with a card buss pcmcia card made by Quantech. I however can not get it working. The only function that works is the power turns on when the start button is selected. Selecting the stop button does not turn off the power and I dont know if it should. Since The device can be turned on, that tells me the computer is talking to the PCS500.
I have checked all the voltages and the only one that dont check is the +12V however the power supply is only a 9V unit so I suspect the 12V is a missprint.
I am confused, in the troubble shooting for no trace you seem to be saying to use the dead scope with no trace to check waveforms on the dead scope?? Perhaps something has been lost in translation.

I am running Win Xp SP3
I am useing pclab 4.05. I have not tried the older version
In device manager under driver I get driver provided by Quantech version 2.10.0.0
Driver details show parport.sys in systen32/drivers ver 5.1.2600.5512. That is confusing as thats not a Quantech driver but a Microsoft driver.
Under resources I find that I can set the IO range to just about anything as long as there are no conflicts
I have tried several IO ranges with matching ranges put into pclab 4.05 and all I can do is turn the device on.

Any help would be apreacated
Thanks

Maybe the LPT port output of the PC can’t supply enough voltage (or current).
Please check the voltage over C49 when the scope is on. Voltage should be about 3V or more.

Can you notice any change at the outputs of the shift registers IC4…IC7 when the scope settings (V/div, Time/div) are changed in the software?

At last got it working. Pulled all the opto isolators and pluged tham back in. Used port 0400 and viola it works.
