I'm currently trying to use a optical detector that use a USB Serial adapter(FTDI). The device is seen by windows and NI-MAX as working, but I don't get any answer from the instrument. Even using the manufacturer software that doesn't use any NI ressources.
If I install the driver and the software on a clean computer, it is working. When I install NI-VISA it is still working as long I don't try to communicate with it. After I try to communicate with it using NI-MAX, it doesn't work anymore. Rebooting the computer doesn't help. I have to uninstall NI-VISA to get the manufacturer's software works again with the instrument.
Any idea?
Thank you
