Re: Interfacing U2000 Hitachi spectrophotometer to pc via RS232C

Hi there!

First you need to know if your PC has serial port or only USB ports. In case you have only USB ports you'll need to convert the data from your device to USB using a serial-to-USB converter.

It's very easy to make LabVIEW to "hear" a serial port (even if connected to a USB port) using VISA (check at 'All programs > National Instruments > VISA'). You'll find the proper nodes at the functions pallete at 'Data Communications > Protocols > Serial' (I've attached an image). Using the nodes is pretty simple, remember you have Ctrl+H to view the context help and also the detailed help option to fully understand every block and even to find examples.

Hope this works, let me know!
