I created an excel document to generate all the RS232 codes that I could find.

This includes all the discrete commands as well as the hard to find numeric digits, smart hub, netflix, and many more.

You can use the document to create your own codes too. (direct channel, volume, etc)

The document will automatically generate the serial string with the checksum included.  It took me several hours today to find and test these codes, i hope you guys can make use of this.

Great job, thank you. This is really valuable. What resource did you use to generate all of this? Samslung isn't really forward about this type of control.

I combined several documents that I found on the web. Then I figured out the formula for excel to build the serial strings and checksums.

Mighty fine job indeed. I am new to RS232 and Excel for that matter. Is there a formula for inserting those commas in the URC strings?

here is the formula that i used to combine all 7 bytes and add the commas between them.

=CONCATENATE(D4,",",E4,",",F4,",",G4,",",H4,",",I4,",",J4)

i just now realize that i posted this in the wrong section....

 

Thanks Mr. Tape.

I don't care what Brendon says about you. You're alright man ;-)

yeah, screw that Brendon guy.
 

I'd really like this file but I can't see anything when I click the link.

Strange. Download works for me. I'll email the file to you.

ok guys don't laugh at me too hard, I am a complete newb at all this stuff and terminology etc. :(

This doc is great, I have been fishing around attempting to find information on serial control to a new samsung LED tv ( just bought a few weeks ago). Has Ex-Link port on screens back panel.....

What I am attempting to do is Control (ON/OFF) capabilities for the display via "HEX" code, from a Asus Chromebox i3 PC...

via the Excel doc (downloaded fine for me), I see Power Toggle, Power Off And Power On first 3 rows... I see "Raw String" "URC Format String" then the List of 1-7 Byte.... Are any of these in HEX? or are any of these hex codes that i can use?

The software platform I am using has ability to put in the established Hex codes for ON/OFF PWR and will send the codes with the timing of the application...

Any and all advice on subject matter would be amazing, again green and trying to learn the ropes... this site has been a blessing, but at the same time a headache (on my part) as I get lost in translations lol

Cheers,

both strings are in hex.  the ones that say URC Format have commas between each byte, because that is how the URC controller expects hex codes to be formatted.  this is different for each control system.  the raw string just has a space between each byte.  this may or may not work for your control system.

are you using a software program loaded on the chromebox? if so, what is the name of it?

Duct Tape, Thank you very much!

Question: are there any commands to get power and volume state of the TV? Does it send any answers for the commands?

Thanks Duct Tape for making the spreadsheet. It's the checksum that always gets me.

I am able to download the .zip file and extract it but when I try to open it, the program locks up and won't load the spreadsheet. I am using Open Office (4.1.0) and am wondering if that's why I am having the problem. I can't exit out of the program or even close it with task manager. I have to end the process in task manager. I tried changing the file type from .xlsx to .xls but it didn't like that one bit.

Thanks for any help (anyone)

I will see if I can convert it when I get to my laptop.
