Hello All, I am receiving the VISA Serial Configuration Error: 1073807360. I have attached a screen shot of my code for reference. I am communicating with a Arduino Uno over the serial port (COM 3). I send a byte to the arduino first, and once the byte is received the arduino outputs a certain command. So lets say I send it over the serial port from labview a 0 to the arduino, I will output pin 2 HIGH etc etc. I tried to reconfigure the stop bits on the port from 2.0 to 1.0. I read in another forum that the stop bits could be the problem. I also tried changing the flow but this did not work either. This is for a long term experiment, so this error can not pop up. I am using a NI 6030E with a SCB-68 to read in voltage. And a NI PXI 6527 to send out digital signals. This is the reason for the 2 DAQ Assistants in the 16-iteration for loop. Also, I can easily solve the problem by stopping the VI and resetting the COM port, but the error still appears about 3 days later. Any suggestions would be helpful. If this is not enough info ill be happy to provide more. My brain is fried from this problem. Thank you!!

I fixed the problem. I use a self powered USB Hub to connect my arduino. I guess it is a powerline issue that causes windows to hang up on the port.
