Samsung TV RS-232

TurnipTruck · April 2014

Greetings,

Most of the modern Samsung TVs claim to have RS-232 control available through the 3.5 mm jack. I cannot find any documentation on it anywhere though.

Does anyone have any knowledge of serial control of Samsung TVs?

Thanks.

See page 43 of this document for the protocol:

Here are commands that I sent to a ME32B that worked:

DEFINE_FUNCTION tvCommand(INTEGER nCOMMAND){
    SWITCH(nCOMMAND){
	case TV_POWER_OFF:
	    SEND_STRING dvTV, "$AA,$11,$FE,$01,$00,$10"; // power off
	break;
	case TV_POWER_ON:
	    SEND_STRING dvTV, "$AA,$11,$FE,$01,$01,$11"; // power on
	    WAIT 60 tvCommand(TV_INPUT);
	break;
	case TV_INPUT:
	    SEND_STRING dvTV, "$AA,$14,$FE,$01,$21,$34"; // hdmi
	    WAIT 20{
		tvCommand(TV_VOLUME);
	    }
	break;
	case TV_VOLUME:
	    SEND_STRING dvTV, "$AA,$12,$FE,$01,$37,$48"; // volume = 55
	    //SEND_STRING dvTV, "$AA,$12,$FE,$01,$4B,$5C"; // volume = 75
	break;
    }
}

Baud is just the standard 9600 N 8 1.

I will give that a try. I am asking about the consumer TVs though. I would suspect that they may be different than the commercial model documentation you posted.

Thanks.

It works on consumer TV*but you are never able to get it on as it switches off the rs-232 port when it's in standby

Turn off all 'eco' settings and it will no longer kill the serial board when in standby. They do this out of the box to achieve EnergyStar ratings.
