Media and Control via Ex Link

[Fredde87]

Hi there,

I was wondering if anyone has the RS232 commands needed for the Media button and the control buttons (play, pause, stop, rewind, fastforward etc)? I have been searching high and low and attempted ever combination I can think of but no luck...

The TV I have is a UN40EH6000 but I suspect it will be the same for any Samsung TV which uses these buttons...


Best Regards

p.s. I'll paste all my other commands I have below which I stole from a Crestron module for people if they are interested as I haven't seen all of of these on public forums. You'll have to calculate the checksum yourself though by taking 0x100 minus all the values in the command (so the checksum for Power On would be 0x100-0x08-0x22 = 0xD6)...

Code: Select all

Hi,
Could you explane a little the structure of UART command? As i understood, this is 6 bytes sequence to be pasted to UART console? and checksum must be the 7th byte? For example:
Power On

Code: Select all

0x08 0x22 0x00 0x00 0x00 0x02 0xD6

Is that correct?

Hi yes your example is correct, the checksum is the 7th byte. Samsung TVs uses hex commands so in Crestron for example you would put in the command as "\x08\x22\x00\x00\x00\x02\xD6"

[Fredde87]

Sorry just a thought, does anyone know if its possible to find the Ex Link commands in the firmware somewhere? Could I extract a firmware which has Samsungs 'Medi@ 2.0' support and then maybe find the commands in a hex editor somewhere?

Same commands than "FaNet Auto AV control" Can be used through USB also.

Byte1 : Header 0x08
Byte2 : 0x22; Number of bytes in command and value below; 0x22 means size=4 (In fact : (size<<3)|0x02; I don't know yet what 0x02 is)
Byte3-4-5 : Command to send on 3 bytes (0x0d 0x00 0x00 means 'send key index'); can be found in some TV user's manuel.
Byte6 : value for above command (key index for example; see here for key index)
Byte7 : CRC = 2's complement of the sum of all bytes on 8 bits

This is a simplified FaNet frame. Genuine FaNet frames have a 0x1f header and a different CRC.

Try :

Code: Select all

0x08 0x22 0x0d 0x00 0x00 KeyIndex CRC

KeyIndex can be found here

Hi oga83, thanks for that! Unfortunately that does not work for me. The menu button works for example (0x08 0x22 0x0D 0x00 0x00 0x1A 0xAF) but the tool button (0x08 0x22 0x0D 0x00 0x00 0x4B 0x7E) does not. I also created a script to try every single possibility (00-FF) with a 1 second delay in between each command. At no point did the TV press the Media button or the Tools button. I am not 100% sure about the rest (play, pause etc) as they don't do anything unless I am already playing a video and for now I am focused on getting the Media button to work...

Could there be another command used to access it? The reason I ask is because the other commands (not the 0x08 0x22 0x0d) seem to be roughly based on the Menu structure of the TV (all video commands are 0x08 0x22 0x0B and then the audio ones are 0x08 0x22 0x0B and they are then accessed in the same order as they appear on the menu structure). So I am thinking since you can go to Applications under the TV Menu and select Media then maybe there is a separate command to get to this menu?

Sorry, I don't know. VK_MENU and VK_TOOLS are working for me.

Very nice info here! Good thinking.

@ Oga & Fredde: I don't see why the key codes should not be at least somewhat model dependent, especially the keycodes relating "features" distinct to models. (I.e. "Smart" button, and media players etc.)

By the way, would this code work, to switch from Air to Cable/Satellite tuner?

Code: Select all

TVTuner: 08 22 0A 00 00 00 CC
