Reading serial com port

[Alex C]

Hi there,

I have been trying to connect my device to my laptop using a USB-RS232 converter. I need to get information such as frequency vs. amplitude of the signals and i have been using the example (Spectrum analyzer) to test it. However, i could not get the program to run correctly as it always returns error. I am using the I/O class->inst and inputted the port which i am using to test the device. Can someone tells me where goes wrong? Thank you

What is the error that you are getting? Can you attach your vi?

Thanks. This is the one that i am working on currently. So whenever , i switch the I/O port to the port that i am using now, Error -1073807253 occured and the possible reasons stated is "VISA:  (Hex 0xBFFF006B) A framing error occurred during transfer.". Once again thank you.

One thing you could do is actually specify the spectrum analyzer and the driver you are using. None of the driver VIs are included in your attachment.

A framing error is often a mismatch in the com settings. Check what the initialize function is setting them to and compare to what the instrument is set to.
