Hi,
Now I have a compactRIO controller NI-9024, and a RS485 module of NI-9871, however I'd like to connect an instrument, say power meter, with RS-232 communication.
I wondered if I can take advantage of the USB port and Serial port on the controller, but I failed to communicate the instrument by the USB and Serial port.
I also wondered if I can use a RS-485 to RS-232 adapter, and use NI-9871 to communicate with the instrument, but I still cannot make it.
Is there no way to utilize the NI-9024 and NI-9871 to implement RS-232 communication?
Do I still have to get NI-9870 to do my project?
Could anyone give me some suggestion?
