dhb,
Could you please be more descriptive as to the problem you are experiencing? For example, do you mean that you are getting an error when reading the last channel of the SCXI-1140 modules or do you mean that the data you are receiving is not what you would expect? If the later, what data are you receiving and what are you expecting?
What language are you programming with? What driver are you using? Can you read from other channels? Can you read the last channel in Measurement & Automation Explorer (MAX) via the Test Panels?
Regards,
