I want to use my own response box which connected with parallel connection in the E-prime 2.

Does someone know which device I need to add at the Experiment Object Properties? Port or parallelPort?

Do I need to install the PST I/O Port or I should not do that?

I have tried many  different options but I always get:

"An error occurred while attempting to read from the Port I/O device driver LastError:0x00000079 "

Thanks
