When you right click on an error out indicator, the first line of the
dialog should be Explain Error. In your case, the error means "VISA:
(Hex 0xBFFF0015) Timeout expired before operation completed." This can
often happen during a VISA Read. If there are no bytes to be read or
you ask for more bytes to read than are available, then the VISA Read
will eventually timeout. The VISA timeout is settable with a property
node so you may have to increase it. Its more likely that you have an
incorrect byte count or there are no bytes available for a read. Is
this a serial or GPIB instrument? Have you verified the commands
you're sending in MAX or anything else?
