Make sure you have NI-VISA installed. You can verify this within NI MAX by expanding the software tree to see if NI-VISA is listed towards the bottom. If you do not see the NI-VISA driver there, you can download and install the NI-VISA driver from National Instruments VISA Driver Download Page.
Once you have this installed, you should see the device within NI MAX under My System»Devices and Interfaces»Serial & Parallel»"Your Device" (ComPort).To communicate to it in LabVIEW you will need to configure the Serial port with the right baud rate and use the VIs supplied with NI-VISA.
