How to count the outputs from 3 encoders?

[HCL2005]

Hello,

I only have one DAQ board (PCI-6229 M-Series) and as I know, the board have two counters:
Ctr0 which uses PFI8 and PFI10 - now using that to count outputs from my first encoder
Ctr1 which uses PFI3 and PFI11 - for my second encoder

But I have 3 encoders, can I use other PFI pins on the DAQ board to count the outputs coming from my third encoder? Is it possible with just one DAQ board? Did I miss any example code which tell me how to do this?

Thanks alot.

Hi Kenneth

Unfortunately your DAQ card only has 2 hardware counters on it, so it cannot simultaneously measure the position of 3 encoders. An PFI lines can be used for counter input on your M-series card, however they can only to routed to the 2 counters on the device. If you require a 3rd encoder function an additonal card with a counter would be required.
