Hello,
If you are using a laptop, I would suggest using our
NI USB-485. If you are using a desktop, check out
PCI-485 or you could check our website
Instrument Driver Network to search for a instrument driver specific for your instrument. If you do you can download it on to your instr.lib file in labview and use it in labview under Instrument I/O function pallette.
Let me know if these suggestions helped.
Good luck and have a great day.
Thanks,
Koninika
