I have the NI PCI-6251 card and want to sequentially produce a digital output for the two counter channels. Specifically, I want one counter to be high for 200ms, then low, wait for 10µs, then set counter two to high for 200ms, before waiting again 10µs. This cycle should repeat. Each cycle therefor takes (200+0.01+200+0.01)=400.02ms.
In MAX, I have configured the task so that ctr0 takes the role of counter one while ctr1 takes the role of counter two. 6251 only has two counters. Unfortuanetly I am not seeing a signal on the oscilloscope...
Is my understanding of what the counters are supposed to do correct? Also, In the "Configuration" tab for the task in MAX, it says that the output terminal for both counters should be PFI13...? How are two counters supposed to run of the same terminal?
I'm not sure if I'm understanding the counters correctly.
Many thanks
