Subject: [Emc-users] Questions about Mesa cards
Hi guys, I hope you are doing well
I have a short question to define a setup
For the 7i89, a while ago PCW told me that it could be possible to make a
counter mode only firmware and use only the A channel encoder input since I
only want to sense frequency and not direction. This way I can have 24
frequency counters in one board. Is this easily done via firmware
editing/upgrade?
Thanks a lot for your help

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?
