The commands are issued by placing the ASCII characters of each command between a STX (start transmission) and ETX (end transmission) ASCII control code. For example, to turn off the panel you issue <STX>POF<ETX>, or 02 50 4F 46 03 when seen in hex. | The commands are issued by placing the ASCII characters of each command between a STX (start transmission) and ETX (end transmission) ASCII control code.

Parameters that are numeric (e.g. AMT:0) are spelt out in ASCII numerals; for example AMT:0 would be spelt 02 41 4D 54 3A 30 03. | ||
The panel will respond with a similar-looking string that indicates the command was recognised. If the command isn't recognised, no reply is sent. In Panasonic projectors, it's possible to query the state of the device with commands that begin with Q - e.g. <stx>QPW<etx> will query power status, QIN/QIM will query input source, QSH queries the picture blank status and QAV queries the current volume. Some of these functions may carry over to the plasma screen, but are untested. | The panel will respond with a similar-looking string that indicates the command was recognised.
