other character string. Up to nine ASCII characters can be defined.
<STX><S><D2h><Len><Pre-amble String><ETX><CheckSum>
Where:
Len = the number of bytes of preamble string
Preamble String = {string length}{string}
NOTE: String length is one byte, maximum nine.
Postamble Setting
The postamble serves the same purpose as the preamble, except it is
added to the end of the data string, after any terminator characters.
<STX><S><D3h><Len><postamble String><ETX><CheckSum>
