visa viwrite

[dungd]

When I used VISA ViWrite to write 1024 bytes buffer,
I've got the following error:
"An unknown I/O error occurred during transfer"

In fact, any buffer size that is greater than 1019
bytes will give me the above error.

Please let me know if you have solution to correct
this problem. Thank you.

Hi,

Just a few questions:
What bus are you communicating with? (GPIB, Serial).
What programming language?
What NI-VISA version and OS are you using?
What is the error code of the error?

Thanks,
