Normally, instrument communication is not used on Real-Time systems because communicating over GPIB or Serial is inherently a non-deterministic process. However, the NI-VISA driver can be used in the cases where GPIB communication is needed. For this reason, you should ensure that NI-488.2 and NI-VISA are installed on the Real-Time target before continuing.In order to test GPIB instruments connected to your Real-Time target, you must make sure that the VISA settings on the Real-Time target are configured to allow for remote communication. To achieve this:
You can open the VISA Interactive Control by double-clicking the resource under test . The VISA Interactive Control allows you to test communication with GPIB or Serial instruments.
