Hello-
Unfortunately, it's difficult to determine any possible cause for this occurance. It was mentioned in a previous email that the instrument will communicate for a few commands. When does the timeout happen? What command fails? Also, what type of instrument is connected (make, model, etc)? Is this a timeout from the write or read? What is the distance of the Ethernet from the host? Is it possible that another machine is accessing the GPIB-ENET/100? Would it be possible to include the code that communicates with this instrument? Does ibic or VISAic communicate with the instrument without timeouts?
Hopefully, this information can pinpoint the exact cause of the timeout.
