Samsung LED Displays

Turned up this little gem when looking for Samsung UN55JU7100 serial commands.

I hope this helps someone else.

Ive seen that sheet before, I havent seen one with expected responses from the display though.

I had to deal with those, bought by a client to save money after I told them I needed IP controllabe TV's. The response you get from a Power Off command is consistent ($03,$0C,$F1) but when you send a Power On command, they just send you a big stream of random garbage (it looks like a damned memory dump). I'm trapping for the trappable OFF response, then, any longer string after a power up command means it powered up. It's a kludge, but those EXLink ports aren't really designed for commercial device control.

Here are the 4 commands I use to the displays:

Power On: $08,$22,$00,$00,$00,$02,$D4
Power Off: $08,$22,$00,$00,$00,$02,$D5
Audio Mute On: $08,$22,$01,$00,$00, [TVOutValMap, Set to Value 1]
Audio Volume Set (un-mutes audio): $08,$22,$01,$00,$00, [TVOutValMap, CurrentVal]
