What do you mean with "verify"? You should tell how you detect "right" and
"wrong".

Viele Gruesse!

Using Serial Read.vi,I have the following reads string. (HEX)
Example: 8000 0134 0145 00FF
My document of the Programer Guide, define as:
80 1. byte is Syncronize Start Packet
00 2. byte is Version Protocol
01 3. byte is Revision Protocol
34 4. byte is information 1
01 5. byte is information 2
45 6. byte is information 3
00 7. byte is information 4
FF 8. byte Syncronize End Packet
I need to present in an indicator the status of these information.
Thanks

There are two ways I can think of.
First, you can use "Scan From String" wired to your string output to get the
particular byte that you are interested in.
Or, you can convert the string to an array with "String to Byte Array" and
then use
"Index Array" to get the proper byte. I like this method best. It's easier
to work
with arrays than strings.
