Hello,
I am currently trying to communicate to a Serial Port mainly using the National Instruments labVIEW toolkit. I first used the "device manager" to view which COM Port my device is currently connected to, where it showed COM 4 & that the device labelled "Texas Instruments" was described to be "working properly". I went to NI MAX to obtain the same information and test the communication through that port where COM 4 has a Port Description "Unknown" and at using "Open VISA Test Panel" it gave a message saying "Error opening resource: ASRL4::INSTR VISA (Hex 0×BFFFF0072) The resource is valid but VISA cannot currently access it."
View attachment NI MAX - VISA Test Panel Error.bmp
An example run through labVIEW also to simply test the Serial port (COM 4), also gives an error at attempting to communicate with the serial port. Even though the device manager continues to say COM 4 is connected to Texas Instruments.
Any idea what we could be doing wrong?
Thank you!
