Samsung RS232 Control (RS232C)

All codes sent are in HEX format.
(Sending the below commands as ASCII characters will not work, codes muse 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.

The codes represented below are broadcast codes and will send the command to ALL displays if connected:

Your control system syntax for sending HEX may vary.
For example, in RTI, hex codes are sent using a \x in front of each HEX character.

From the code list above, the 'Power On' command in RTI would look like this:
\xAA\x11\xFE\x01\x01\x11
