Here is what I got from Cognex support:
Since the IS2000 series does not have Spreadsheet capability, it does not work with the In-Sight SDK.
Here's an excerpt from the SDK Release Notes (that come installed with the SDK):
"The In-Sight Micro 1020, In-Sight 2000 series and In-Sight 7020, 7010, 7230, 7430 and 7432 are not supported with the In-Sight SDK."
I just wonder if your counterpart ever done any work with IS2000?
