Well, I got it working. And it works for power-on too, although I suspect that is because my display is newer (2009 model)? I must be configuring hyperterminal wrong because when I use this plugin to a tool called "Eventghost", it worked perfect. Thank you, Fiasco!

Go here to buy your cable, if you don't want to make it (p/n 6049):

Speaking with my buddy, UN46b8500 and UN55b8500 have worked, including power on from off state. These are LED TVs. It worked out of the box, with hotel mode in its default mode off. He thinks the 6000 series will work but he doesn't have that unit in house yet. Plasmas are a different chassis so there may be different protocols and settings to get serial to work. Given that plasmas require more energy it is very possible the chip set is also turned off when the display is; Sharp is famous for this design and there was the infamous Sharp/Pioneer collaboration that had the same issue.

I spoke with my buddy this morning to get his latest report and he claims out of the box control for all commands, including power on, for his 46 inch LED Samsung. He was curious why hotel mode was enabled so to that poster I pose that question.

I have a Samsung LED scheduled for a Prodigy install in a week or two. I do find it amusing you are purchasing a serial cable. Has the ability to solder really gone the way of dinosaurs?

you can find that cable cheaper, but even at $10 it would be hard to make that cable yourself for cheaper. not to mention the fit and finish.

Yeah, I originally made my own cable, but after pulling my hair out trying to get the display to respond, I decided that maybe my homemade cable was suspect (it was fine).

BTW, my display is an 09' plasma. PN58B650

I was able to get EXLINK with power on and off to work with a Samsung PN50B550

I ran across this document to get RS232 working on non CI+ samsung televisions.

they are also hacking the samsung firmware to run their own custom applications pretty cool. There is also an effort to control the device over ethernet, that would be really cool.

Hi all.

I need a little help.

I am starting to test my Samsung LCD RS232 functions. I also used Eventghost and it responds to some commands so I guess the LCD is properly configured and the cable is working.

My problem is that I want to manually test the commands but I don't know how to. I already tested hyperterminal and similar programs with no success. I am a bit confused about the format of the commands I must send.

I have read in this topic alone 3 different formats:

\x08\x22\x00\x00\x00\x01\x2C
08 22 00 00 00 02 D4
$08,$22,$01,$00,$01,$00,$d4

None of the different formats worked (tested various commands). I took a look at the format Eventghost uses and it seems pretty basic: 08 02 prefix following by the command part. But I was unable to see if it makes some kind of formatting or not.

I know that the essential part is the format in the second example and the \x and $ are just formatting characters but... what is the format expected by the tv? Which one should I use in realterm or hyperterminal?
Also do I need to send Line feeds or carriage returns after that?

Any help would be appreciated. Thanks.

To use hex in Hyperterminal you must first conver all the values to decimal for example 0D would be 13. Then you can hold down the Alt key and type 13 and it will send the appropriate character.

Or you could just use a terminal program that understands hex like RealTerm. http://realterm.sourceforge.net/

Thanks. I'll try that.

I know this is an old thread - has anyone tried using a 1/8" TRS cable direct between the multi-port on a RTI control processor and the Samsung Ex-Link port? or does the pin-out need to be different? Trying to avoid going to a CM232 then back to 1/8" if possible.

It will not work . RTI does not use standard TRS . you have to use cm232

I use Ex-Link with all my installs, works great.

I use the physics systems server. The xml file is viewable. here is the hex for some commands. enjoy! If you need another specific button let me know if I have I'll add it.

Question asked by wireman121 was regarding 3.5 mm. TRS ( tip , ring , sleeve ) from RTI controller to a Samsung EX-Link port . Samsung is using that standard , unfortunately RTI does not . Therefore he has to use RTI cm232 cable with another 3.5mm to DB9 adapter to make it work . Ex-Link does work great and all necessary codes are already a part of RTI's database . There is also a beta driver floating around on RTI dealer forum .

You could always just use the Ethernet cable coming out of theirs-232 port on the xp processor, cut one end off the Ethernet and solder the wires to the other end of a stereo cable (cut one end off)- no db9 adapter required.

Please send me these codes, thank you very much.
