How can I implement a Digital I/O counter with a maximum source frequency of 80 MHz (like 6602 board) using CompactRIO?

How can I implement a Digital I/O counter with a maximum source frequency of 80 MHz (like 6602 board) using CompactRIO? It appears as if the Digital I/O modules for CompactRIO are much slower than this.

Thank you,

Hi Ray,

The highest frequency input we offer for C Series modules is 20 MHz if you are doing LVTTL and 10 MHz for 5 V TTL.  These modules are the 9402 and 9401, respectively.  Unfortunately, there is no 80 MHz input on this form-factor.
