Hi,
From the NIDAQmx C reference help:
The following table lists the output terminals for counter output. You can use a different PFI line for any of the output terminals.
Ctr0 | Ctr1 |
---|---|
PFI 12 | PFI 13 |
So from that you can select any of the PFI lines....the default ones of course are Ctr0 output and Ctr1 output...
Teorically the counter clocks you talk about you can use the 20 Mhz and the 100 Khz reference clocks for generating your output signal... so precission should be enough...
Let me take a look for something more about using two counters with labwindows/cvi...

Hi,
1. You can see which routes you can do under Measurement & Automation Explorer (MAX). Go to devices & Interfaces and selecte your board. Then go to the Device Routes Tab. Over there you can see which terminals u can interconnect.
2. Use the Select_Signal function to route those signals.
Anyway, I don't understand why do u need that... u can output 8 wires from the counter output and everything is resolved....

is just because i was thinking about a problem of "fan out", i have to feed 4 devices so i was thinking of using one output channel for each device, but you are right, maybe i can feed all of them with the same, I couldn't check it for the moment, so i think there is no problem! Thank U anyway!!!!!Anyway, I don't understand why do u need that... u can output 8 wires from the counter output and everything is resolved....

mmm
Well... you can always insert a drive or an optocoupler for every channel u wanna take out...
I think is better just to spend a bit (time and money) making that than using extra resources of your board that u can use for another things 😉
