You're supposed to change it to the actual VISA resource that the instrument is connected to. In you case, you don't have a GPIB controller but are connected to a serial port. Change it to the com port you're plugged into (i.e. Com1 or Com2). You also have to hope that the vendor has support for a serial instrument in the driver they wrote.
Any documentation is provided by the vendor. If they followed the NI Instrument Driver guidelines, there should be a top level VI called te336x Example or Getting Started that demonstrates how to use some of the lower level functions in the driver.
