The TV only confirms communication when they reply, they don't reply with any specific info unfortunately.

This has been tremendously helpful!

Any chance anyone has the command to go directly to YouTube? I really, really need to get that fixed.

Thanks!

I don't have the code, but you may be able to figure it out yourself.

If you look at the difference between the Netflix and Amazon codes, the only thing that changes is the 6th Byte  (and the checksum, but disregard that for this purpose)

Netflix
08 22 0d 00 00 F3 D6

Amazon
08 22 0d 00 00 F4 D5


If you edit the 6th byte, to something else, it may switch to a different service.  I'd try F5, F6, F7 and so on.  If the F's don't work and you really want to speand a lot of time on it, you could run through all 256 possibilities.  (00-FF)

The excel sheet will automatically calculate the new checksum for you.

Post back if you find more codes and I'll add them to the list.

All,

This is an awesome resource. Thank you all for putting this together and contributing to it. I can say Samsung makes great TVs but there is a lot to desire with regards to its support.

I have an installation that involves a few TVs of the following models: UN65TU8000FXZA (TU8000s of different sizes) and a QN85Q60TAFXZA. All of these TVs no longer have the 3.5mm Ex-Link port we were expecting to have.

From a communication from Samsung we understood USB was needed for control now, but Samsung buried the "USB Serial" setting in the service menu.

We use Kramer AV Controls to design our iPad custom programming. Kramer tells us Samsung and LG have gone the authentication route and they cannot support yet IP control. This leaves Serial control as a limited-reliable solution (no feedback as far as I know). IR is supported but it's the less desirable option.

We have tried all the suggestions in this thread with regards to getting USB Ex-Link working but we get no PowerOn or PowerOff or any command executed at all.

We are using a standard RS-232 cable (USB to DB9-F with a PL chip). I believe it's also called a TTL cable. We use a GlobalCache iTack IP2SL gateway (has a DB9-M port) to connect to TTL cable.

//
Service Mode settings: --RS-232 Jack: UART --EXT Link Support: ON --USB Serial: ON Hotel/Hospitality Mode: OFF
Standard settings: --AnyNet+: OFF
EX-Link com port settings: --9600 baud --8 bit --no parity --1 stop bit --no hardware flow control
//

When testing a direct serial connection from a laptop (with a USB to Serial dongle) and the Hercules utility, all we is "double-quotes" when we send the HEX codes from the XLS shared here for power-on, power-off or power-toggle.

To summarize, we have not been able to get ANY command successfully via Serial-USB to any of the TVs. Some have mentioned PowerOn only worked. That hasn't been our case.

If you can think of any thing that could be causing the total disconnect, please let me know.

Thanks,

Additional info.

I have been trying to locate a distributor for the following adapter without luck.

Perhaps, one way would be to make our own cable using the following info:

Does someone have any actual experience with the USB cable that can share?

Hi,

Is there any code for starting Youtube ?

Thanks

see post 93

Experts,

I'm still experiencing issues getting any command through Serial-to-USB as i my Post 94. Today I'm testing on a new Samsung UN65TU8000FXZA. Similar to one I tested before. No luck. I can't believe this is not even working for Power On.

What am I doing wrong?

My settings are the same as above:

//
Service Mode settings: --RS-232 Jack: UART --EXT Link Support: ON --USB Serial: ON Hotel/Hospitality Mode: OFF
Standard settings: --AnyNet+: OFF
EX-Link com port settings: --9600 or 115200 baud --8 bit --no parity --1 stop bit --no hardware flow control
//

Please help!

you tried reversing the Tx and Rx pins on your cable?  That's the first thing I do when things should be working, but are not.

I have actually a prolem with a 32" Frame. I can control it perfectly. Unless I power it off for more then 30 sec.. Then it's no longer reacting on the Power On command. After power it back on via remote, it works again. also the power on command if I don't wait too long. has any one else such experiance?

Same here with 32 Frame
Other frame size do not have the same behavior
I noticed the delay after it’s no longer possible to send any RS232 command is around 10s

This is related to firmware

Hey all, thanks for this wonderful thread, and thanks Duct Tape for the list of commands. You're a life saver. I now have a functional solution on the Frame 2022 using RS232 which I've chosen for two reasons...

1. IP is flakey and unreliable on the Frame... Authentication tokens are often needing to be refreshed manually, power control switching between Art mode and regular tv mode is flakey and unpredictable, and there is no brightness control which is necessary due to the poor sensor control over Art mode brightness in low light.
2. Infrared is not great for me as I am building a custom wood frame that will block the receiver. There are forwarders etc but I haven't seen a lot of success with them outside of units such as this, which they don't want to sell to people who don't own their deco frames.

So here's my setup for anyone else who might be interested...

TV

• The Frame 2022 65" (QA65LS03BAWXXY - Australia)
• Port: "Service" (it's not called Ex link in Australia)

TV configuration

• Service mode: RS-232 (default)
• Jack: UART (default)
• Ex link support: On (Off by default)
• USB serial: Off (default)
• Anynet+: Off (On by default)
• Hotel mode: Off (default)

Controller hardware

• Raspberry Pi 4
• Pi -> USB DB9 adaptor (Amazon AU link) -> DB9 3.5mm adaptor (Amazon AU link) -> TV

Controller software

• Node Red running in a docker container
• node-red-node-serialport package installed (version 0.15.0) to send the RS232 commands
  • Note: The latest version (node-red-node-serialport 1.0.1) on arm based processors silently fails when attempting to open a connection to the USB serial port and kills the running instance of node red, therefore required manual npm installation of 0.15.0. This is a known issue they'll fix in future versions.

Controller / node red configuration

• Expose the USB serial port / device in docker-compose config
  • /dev/ttyUSB0:/dev/ttyUSB0, or
    • ​/dev/serial/by-id/YOURDEVICE:/dev/ttyUSB0
  • group_add:
    • - dialout
• Configure node-red-node-serialport
  • Serial port: The port specified in the docker config, i.e. /dev/ttyUSB0
  • Baud rate: 9600 (115200 failed to send commands for me despite others reporting this as working)
  • Data bits: 8
  • Parity: None
  • Stop bits: 1
  • All other config options: Default
  • Note: There is no hardware flow control implemented in this package, therefore no ability to enable / disable it. Disabled by virtue of not being supported :)

Node red flow / commands

• Sending the HEX commands to the TV using the node-red-node-serialport package is achieved by sending buffered data. Here is an example (download node red JSON flow)
  1. A node red inject node (or any other node that initiates a flow)
  2. A function node that passes through buffered data as individual bytes (i.e. for the Power On HEX command of 08 22 00 00 00 02 D4)
     • msg.payload = Buffer.from(["0x08","0x22","0x00","0x00","0x00","0x02","0xD4"]);
       return msg;
  3. A 'serial out' node that is configured as per the "Configure node-red-node-serialport" step above
• Initiate the flow via clicking the inject node, or whatever other flow trigger you use, and the command will be sent to the TV

And that's it :) It works flawlessly. Because it's implemented via Node Red, I can use this to send RS232 commands via any automation / flow in Node Red. Some things I have in place:

• Zigbee wall switch automations (also available using my harmony remote)
  • Button press -> Deconz zigbee event -> Node Red -> Toggle tv on / off
  • Long button press -> Deconz zigbee event -> Node Red -> Dim tv brightness
  • Double button press -> Deconz zigbee event -> Node Red -> Increase tv brightness
• ​Home assistant list helper
  • ​Select art mode, tv mode or off -> Node Red -> Set tv state ​
• ​My next automation will be to automatically detect room brightness via a Lux meter and then feed brightness data to the tv

Hopefully someone finds this helpful. Feel free to ping me if you have any questions.

CriXiD - thanks for the above post!

I am trying to get EX Link working on my Frame 2022 75" (Australia)

You mention the need to enable EX Link - can you please advise where that option is? I cant seem to locate it.

Thanks!

I haven't needed to enable it on recent models. But you'll find the option in the hidden service menu. The method to get into that varies by TV, but it's a series of button presses on the original remote control, followed by turning the TV on. I'd google "Samsung Frame TV hidden service menu", and I'm sure you'll find it.

Thanks Duck Tape.

I have found the service menu, but there is no EX Link Setting.

CriXiD specifically called out needing to enable it for the 2022 Australian Frame, hence why im asking as it might be somewhere else.

I just cant get any responses, tried reversing the pins on the cable, but getting zip back from the TV, with and without Anynet+ disabled.
