Labview is very useful to communicate with test instruments. Typically, this is done using GPIB. It is possible to communicate with instruments using the serial port (RS-232).
You should verify with the recommendations from the manufacturer of the equipment and make sure that there are commands available to configure, control and obtain measurement data through the serial port.
You can try to communicate with the equipment by using a software like "HyperTerminal" in Windows. Basically, what you can do using HyperTerminal, you can do within LabView.
There are many posts that describe how to implement serial communication using Labview. Simply do a search on serial communication.
