If you have LabVIEW installed on your computer, you may use the VISA Interactive Control
program to connect to your 3411. VISA Interactive Control is a separate program written by National
Instruments meant to test communication with any VISA compliant instrument. By implementing
the Test and Measurement Class Specification, the 3411 is now VISA compliant.
It is possible to write custom LabVIEW programs using VISA control blocks to connect the 3411.
You must know the VISA instrument descriptor of the 3411 to do so. The instrument descriptor
will follow this format:
USB[board]:: manufacturer ID:: model code:: serial number[:: USB interface number]::INSTR.
For the 3411 it will appear as USB0::0xxxxx::0xxxxx::[units serial number]::INSTR.
Writing LabVIEW programs is beyond the scope of this manual, however there are examples
implementing this technique found on the Magtrol homepage.

You may use LabVIEW or any other programming language to write a custom program using sockets
to open a connection to the 3411. The unit listens on port 3411 for any incoming connections. It
is beyond the scope of this manual to discuss sockets programming, however, there are examples
programs implementing this technique available on the Magtrol homepage. Download the Mag.
