Anyone use the EX Link control for Samsung TVs? We have had issues with them a 2 jobs recently.
One job, the screen would randomly show "Not Available" every few minutes. This happens when the Power On command is sent, but on this specific display the message displays every few minutes. After unplugging the EX Link message stopped appearing. There are 2 Samsung TVs hooked up with EX Link and the first one has no issues.
Second job we have multiple TVs hooked up with EX Link and there has been issues with the Crestron processor locking up and the power off a zone will shut off that zone, but turning on another TV.

I was wondering if anyone has had the same issue, and if anyone knows where the issue stems from.

Thank you

I've been testing it on 4 different Samsung TV's. Haven't seen that issue yet. I did have a problem with getting feedback because my wiring was wrong at first. I am using a ML600 cable for my connection from the TV to the Room Box. Three of the TV's are running through a DM switcher (with DM-RMC-100) and another is coming off a PRO2.

How many wires are in that cable? Would there be any difference than a standard 1/8" Stereo cable?
Do you have it working on a system with more than one Samsung display?

We have checked wiring, and we do receive feedback. I want to say all of ours are running off of Room boxes as well, but I cannot say for sure.

Nothing fancy about the cable. I just had a bunch of ml600 cables so I used those. I have three Samsung displays connected to a DM 6x4 switcher. The other output is a sharp 80 inch. Two of them have DM-RMC-100's connected to them and the other has a scaler connected. All of them are 46" displays. I think two of them are the 6500 series and the other is the 8000 series. The other system has a single Samsung display connected and it is connected to a Pro2 in our showroom. That is an 8000 series 46 inch and has been connected since that model was available with no problems. The showroom system is using Crestrons ex-link module and the DM system is using our module.

Is the HDMI Control turned off at each display? I think it's called Anynet.

I have seen the not available message on my Samsung when I have sent it the same input command that its already on, you can either lock it to HDMI 1 or use a variable statement to keep track of which input its on since there is no feedback from the TV.

I will have to double check the Anynet control...

We are not sending any input commands, so that would not be a cause.

The current big job we have with 6 TVs we just swapped to IR control, but we will have to look into the issue more.
Thanks for the ideas and keep'em coming and I will post anything we find.

Are you getting real feedback from the EX-Link interface? What module are you using?

We've been using RS-232 with Samsungs for a while, but my understanding (based on past threads here, and posts in the Yahoo Crestron group) is that the Samsung EX-Link may spit out an occasional "Ack" or similar but does not return power status or input. Unlike LG / Sharp / Panasonic, I've never seen a list of commands to query the TV.

(Have always used one of the Crestron module (UN55ES8000); it has signals for feedback, but I've never seen them working.)

Would anyone object to a me compiling all of the Samsung Ex-link 232 info on here into one post? (probably with lots of links to other threads)
I've just spent a few hours trying to find everything and I'm still a bit lost.

The main issue I have is it appears Samsung are not even putting 3.5mm ex-link ports on their UA versions of UN models that DO have it :(

Further googling indicates that these models that lucked out on a 3.5mm ex-link still can do ex-link via either USB or VGA - but here the info gets even slimmer...

I think I've confirmed the VGA ex-link presence on a P2370HD as putting it into HOTEL mode removed the VGA input from the source list.

Does anyone know the cables \ adapters required to do this - soldering is an option but I'd much prefer not to as we're planning to use 232 as much as possible.
