A simple way to use software serial to control RS232. You can also check if the TV is on or off via the command Serial.println(“ka 01 FF”) and it will return “a 01 OK01” (on) or “a 01 OK00” (off).Īfter testing the commands from my computer via null modem cable I ordered a RS232 to TTL converter module. To turn it off again I use Serial.println(“ka 01 00”). For example, if I would like to turn on my TV, the command is Serial.println(“ka 01 01”), where “ka” is the command for power. The commands are built in three segments: “ ”. Then I read the manual (after 5 years of curiosity) and apparently you can control almost everything in the TV with simple serial commands and it´s well documented in the manual. I have always been curious what that port does. I just got my TV controller working and would like to share this to you.īehind my LG TV there is a RS232 port.
