nnio,
Connect phase A of the Quadrature Encoder to the SOURCE of the counter to be used and connect phase B to the corresponding DIO up/down line (DIO 6 if phase A is connected to the source of counter 0, or DIO 7 if phase A is connected to the source of counter 1).
With this method you can connect phase A and B of your first encoder to counter 0 and phase A and B of your second encoder to counter 1.
How Do I Use a Quadrature Encoder with My Data Acquisition Board?
