All codes sent are in HEX format.
(Sending the below commands as ASCII characters will not work, codes must be sent as HEX)
The model of displays that these codes work on are typically video wall or commercial style panels. The RS232 port is labeled "RS232C In"
These types of displays typically have an RS232C In and an RS232C Out port because they are intended to be daisy-chained together.
To control a Samsung Commercial display over RS232, press the Home button and navigate to ID Settings --> PC Connection Cable and choose RS232C cable. If you don't make that change, you will not be able to control the system over RS232.
The codes represented below are broadcast codes and will send the command to ALL displays if connected:
