In Labview, Im used to basically drawing a line from the write to the input node of the USB read. There is not an input node on the USB read to control the flow. How do you read the response from the packet I sent? Here is my code: [{"id":"9a21f667.8fc0c8","type":"tab","label":"Flow 4","disabled":…

Try setting the serial config node to split on 0x03 & return a buffer [image] See if that give a more sensible response EDIT... And send a copy of the results once more & a description of what you believe the reply means (same as I asked before please)

Which debug is giving you replies? suspect it's the top one attached to the serial request & the 2nd serial in node isn't required.

And now you are getting data back, can you do the following?...
