Hello
I have same problems when i use the counter of the board pci 6221.
The problem is,
- when the signal is less than 5/4 vols the counter dont measure. So i would like know how is possible measure signals more low than 4 volts. Because i have another board (pci6023E) and with this board i dont have ths problem. The conuter works very well.
I don t know if is necessary put any kind of reference.
in Attachment i send the kind of signal i have and is possible measure with the board pci6023E but dont work with the board pci 6221. In this signal i measure the number of fallings.
Thanks
Marco
