I'm currently working on the development of a Flash Photolysis instrument using Labview 2009 and have recently upgraded our computer but have run into some issues. At random points there is a generic I/O error within the messagesend.vi, but the errors do not occur when using the lamp tool. After doing some research I have found that upgrading our computer has caused some timing issues where the instrument and the computer are not communicating properly.
I was curious if anyone has had experience in changing the PCI-GPIB card settings so that the instrument will ping properly with the computer and fix this timing issue.
I believe you're right! I've found that my error occurs at the GPIBwrite command, would the two strings here cause a race condition during the writing process?
