problems with encoder

[Alejandro_zepeda]

I am having problems reading a diferntial encoder. I have two encoder
conected to a PCI-6071E, I want to read the direction of one encoder. I has
a demo "how to count.vi", I used it and it work. But if I read boths encoder
at the same time I have no reading of the direction.

Any suggestions

Thanks

You can try to separate the two inputs of encoders in two shield cable.
