1st you need to know the communication parameters of the device (baud rate, data bits, stop bits, parity, termination characters). Next you need the proper serial cable from the PC to the device. And then you need to know the command set for the device. The manufacturer or the device's manual can help you determine these.
Next, use Windows Hyperterminal to test the above to verify all is in order.
Now use basic serail read/write vi's that typically ship with LabView. Configure as needed and run to test command and responses out. Search examples under Help for serial to finds these.
This should be a good starting point to writing a LV program to satisfy your data acquisition needs.
