Not intelligible problems with the counter

[M_Pete]

I use
Board: PCI-6601
Soft: VB 5.0 and ComponentWorks 3.0
For my task I use " Buffered Event Counting" mode. If the signal comes the first on "Source" and then on "Gate" all works wonderfully. But if the signal comes on "Gate" the first I receive mistake

Error:-10920
Context: Reading data
Description: "One or more data points might have been lost during buffered GPCTR operations due to speed limitations of your system".

It is very strange. I would like to see zero. Somebody can face with this problem? Or the counter cannot work in such mode?

Thanks.

Pete;

I agree that is a little strange.We don't have such problem reported on our Data Bases.
A workaround you can try is to make a sinle pulse goes to the source, before start the buffered acquisition, and see if that makes the counter keeps reporting a 1 value.

You can also try the same thing on another counter of the board to see if that problem is related to the counter you are using.
