Why do I get an END status after I read 2**32 bytes from my gpib board?

[Joelj]

My application gets an END status after I have read 2**32 bytes from a device connected to the GPIB board. The device has no limitation an the number of bytes transfered and is working in other environments. After I get the END status I cannot read from the device without re-initializing the GPIB.

Hello,
Have you tried disconnecting your current device and connecting a completely different device to the GPIB board? If you do not observe the same behavior, then the problem lies with your current device itself and you should talk to the device manufacturer. If it does observe the same behavior, then problem does lie with the GPIB board and we'll try to tackle the problem.
Also, do you have GPIB+ board or just GPIB? If you have GPIB+ board, you can try and run the analyzer. The analyzer will give you all the information about every communication taking place in between the board and the device. If you have just the GPIB board, try running the NI-spy which will give you a high level driver communication information.
Please let me know if I can help you f
urther.
Good luck.
Have a great day!
