Panasonic th-47lf30 User Guide

Basic format for control data
The transmission of control data from the computer starts with 
a STX signal, followed by the command, the parameters, and 
lastly an ETX signal in that order. If there are no parameters, 
then the parameter signal does not need to be sent.
