A start character, or preamble, is defined by the source. What is your start character? i.e., what are you expecting?

Dear Arrow,

My start charecter is "*02" it is defined by the source. command format is *02|data|*03|OD|OA!

Not sure where your problem is. There are functions to search a string and you just have to specify what you are searching for. It would seem that this is a hex string so be sure to click on the string constant/control and select 'Hex Display' before you enter the 02 value.

Yeah, I'd use Match Pattern to pick apart the message.
