Hi Peter,
Yes, its possible to make "A" only encoders channels on a 7I89/FPGA card
set, what 7I80DB do you have and what other I/O is needed?
My idea is the following:
7i80DB25 ---------> 7i89
----------> 7i85s
----------> 7i74 ---------> 7i70
---------> 7i72
Is this configuration ok?
Basically it's a question of fitting, what version of the 7I80DB do you have?
