Having 3 x P8055 control cards working from 1 P.C

I want to have 3 x P8055 control cards working from 1 P.C. I’ve read the manuals and know this can be achieved. However how many times I try this, the P.C wont recognise all 3 cards 00, 01, 02. I have these cards working well in a singular installation, but I dont want to keep many P.C’s running 24/7. Can anyone tell me how to set up/use 3 P8055 cards independant of each other but from the one Lap Top Please.

Thank You FP30E

Make sure that you downloaded the latest dll update!

If you configured the card addresses like you say and they all run separately on the same system then it should work, if you run the demo application and click the “Find Devices” button and then click the “Output Test” button you should see the test sequence on the cards?

Thank you. Will give it a go…
