When I saw a post about a Samsung LCD with a RS-232 port it certainly caught my eye. I downloaded the PDF Owners Manual for your model and it certainly doesnt show any RS-232 port ( http://downloadcenter.samsung.com/co...02L02-0418.pdf ) The only PC based connections show are VGA and 3.5mm for video/audio from a PC.


Is the back of your TV different than shown on page 6 (of PDF, the page is labeled 4 in the manual)?


I have been trying to find out if its possible to get RS-232-like control through their LAN port, but havent gotten a specific yes or no out of them (waiting on response to email) or anyone in the LCD section of this forum.

As far as being able to use the LAN port for any sort of control....


I finally got an email response back from Samsung this afternoon. However, it only stated that my question needed to be answered via phone from their Customer Service department. I called to verify, and I was told that it is not a current capability of their TV's.

I have seen in the past that you could get everything to work BUT power on. If that is the case make sure that you have the Energy Star truned OFF. One of the things that these mental midgets turn off is the RS-232 when the TV is in energy star mode....

Everything to work but power on with RS-232 maybe. The problem is with the model TV the OP said he has, the owners manual does not show an RS-232 port (and I havent seen one on any of the newer Samsung TVs).


In my previous post, I was talking about lack of support or control over their LAN / Ethernet port, which is intended for RSS feeds. I was hoping since they dropped the RS-232 connection from their models, they would have allowed control over the LAN port, but not the case according to their customer service department.

Thanks for the info guys.

Audio FN - I could not find where to turn off the Energy crap, i mean star.


drvnbysound - There is a rs232 port on this tv, its just not a traditional rs232 port, it is a 1/8stereo mini. You can change the EX LINK port to be AV Control in a Installer Menu.

Chuck78 look for something like power save mode or something like that. It has been a while since I had to do one. I am not aware of any TV that allows you to control through the ethernet jack. Would be nice if they would!!

I have found the appropiate documentation regarding the EX Link. It will certainly be a couple of weeks before I would be able to pull some additional wiring to be able to do this. Please let me know if you have any success with the Power On. What is involved to get to the said "Installer Menu"?

Since I have a home automation system, I've always paid close attention to devices with RS-232 control. From what I have read, Samsung has a history of letting their ports control the TV with the exception of the Power. So while the TV is on, you can control it via the port, but you'll not be able to turn if on via the port if the TV is currently off.


To Samsungs credit, they do not advertise that their TVs are controllable. But many people have bought the TV and then hoped to be able to control it. Unfortunately I've seen this complaint many times in different forums and I've never seen any resolution to the problem. That's bad for those who already own the TVs, but a warning to those looking to control their TVs via their computer or home automation system - stay away from Samsung TVs.


Make sure you reseach your purchases carefully and buy a brand that advertises that their sets are controllable. Even better is to find and confirm the TV has a printed serial protocal available.


Some of Sharps TVs are controllable and most of LGs TVs are controllable. But there are sets by both manufactures that are not, so you have to be careful. Both brands generally print the serial protocol right in the users manual if the TV is controllable.

Well first off I did look into the TV, it did say for service only, but many tvs/projectors say that and you can still use them for control. Second I have had a Panasonic that did the same thing as what I have describe and it was due to Energy Star being turned on which they shut down the RS232 port. I called Panasonic about this and they gave me another firmware to install that disabled the Energy Star and I got my RS232 back. So I was hoping for some info from someone that may have find away around this.


Now my what I could do but would rather not is, to put an IR bug or blaster and turn it on that way. But I would rather not have the little thing stuck to my TV.


Thanks

Sorry, I didn't mean that to be negative towards you personally, but more of a warning for future shoppers. Sorry if the tone of the post seemed like a "told you so" - it was not designed that way.


Honestly I think having a small IR emitter on the TV is about the only option.

This thread has been inactive for awhile....bumping it back.


I am interested in turning on my Samsung LN-T4681 EX-LINK for RS-232 controls. I know that you must enable it in the Installer Menu, but how do you do that?


As for the engergy star work around, would a null (empty) input (eg Composite video input) work for the TV to sense NO signal and go to sleep/standby? Worth a try to fake the TV into sleep/standby mode , and wake when you send an different input command string.


Thoughts?

Ditto, I'm looking into this for two Samsung TV's. I found a source for a premade cable RS232->stereo mini plug here


If you can't turn the TV on via RS232 then it's a dealbreaker. All I've read thus far indicates that.

Any updates on this? I'd love to be able to use an RS232 cable to control the LN52A650. Thanks!
