[DMDX] How to use a Pio 12 card to send outputs and to receive inputs? Dear J.C. Forster  IÂ´ ve a PCI-DIO24 installed on a computer (Windows XP) running DMDX.  I wonder how to make a program in DMDX: A- Questions about output signals 1) Is it necessary a keyword definition to be written in the parameter line for outputs ? Is Keyword  the correct form? 2) I read that I may use the  keyword to Output to PIO12 port. This must be written in the "Experimental items" each time that an output signal is sent? 3) Which number indicates "N" in the  keyword?   B- Questions about input signals 1) Again, I suppose that it is necessary a keyword definition to be written in the parameter line. It is not thus? Is Keyword  the correct form? 2) I need to use a two-button response box that is connected to the Pio card. I think it mappes the responses to Bit1 and Bit2, but when I did the PIO Test in TimeDX, Bit8 and Bit9 changed from high to low. Can I use the inputs in that manner?
