Can you elaborate when you say that you have full EX-LINK serial control working. I have an arduino that I configured to send codes to my q6 65inch and I have almost full support. Every code works except "get status" codes for instance,

Volume(0~100) 0x80x220x400x10x00x00x95

returns not available

Does this code work for you?

Basically I need to know what the tv volume is at all times.

This thread has been incredibly helpful.

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,

-XT

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?
