PCI6601 - Start and Stop of all 4 counters individually in LabView 5.0

[Max26]

Hi!
I work with the PCI6601 card and I want to start and stop each of the 4 counters independent from the others.
To start only one counter is quite easy, but two or more won't work.
I have 4 external devices and want to know the counts of each device that means there are four sources.
The Vi's in LabView 5.0 supports only the AM9513/8254/and the DAQ-STC. Perhaps there is no possibility to work with all features of the 6601 in LV5.0.
I tried it with the counter list and with group# and the listed counters started with the internal frequency. But this is not what I want.
Please give me some hints to "rescue the next nights".
Thanks for your answers!

A couple comments that will hopefully let you sleep well tonight...

1. If possible, use the counter functions whose icon show a "CTR" in the lower right rather than a "123". Do you have these in LV 5.0? I know they were available by 5.1.1, but am not certain about 5.0

2. The 6601 doesn't support multiple counters in a group. To program 4 counters requires 4 config chains with 4 separate calls to "Counter Group Config". Note that each call must input a unique group #.
You'll end up with 4 unique task id's which you can then start & stop independently of the others.

No,I only have the 123-functions.
But its good to know, that i have to start each counter alone.
I will try it today.

Thanks,
