converting serial data for indicator

[Japper]

I have a simple VI that I am using to read streams of data from a serial device.

The data is in a three byte code where the first byte is an "O" and the 2nd byte is

data and the third byte is a don't care end character.

What I hope to do is grab the value of the 2nd byte and use this value to set a ring indicator.

The two problems that I am having is the data sometimes looks like garbage and I am not able

to convert this to a number that the Double ring indicator (knob) accepts...

Here is what I am seeing:

Change the knob to be a U8.  That would make more sense since you are only using a single byte.  Take your string and use the String to Byte Array.  You will now have an array of U8.  Use Array Index to get the second byte and wire it to your knob.

I would also change the display style of the string indicator to be Hex values.  The data will make more sense then.

That did the trick.

Thank you very much!
