I wanted to bump this threat because I saw anther blog post that had some RS232 codes for Samsung that look way different:

For example, Power On..
HEX: AA 11 FE 01 01 11
vs the one in the spreadsheet:
08 22 00 00 00 02 D4
Or do we need to convert the raw string to HEX?
those are both examples of hex strings. the example codes they show are for video wall displays. the codes in my document are for exlink models.
