Samsung LED TVs

Hi

Anyone know if the 'service port' on the back of the Samsung TVs can be used for RS232 control similar to the Pioneer plasmas (RIP).

I rang Samsung and they dont support it.

    Good question. The port supports their "Ex-Link", but that's all I know (it sounds like I got the same response from Samsung that you did).

    Ex-Link works when the TV is on. You cannot power it on though from the off state. I've looked through most, if not all, of the service menu settings and see nothing about an energy savings option or anything that'll keep the Ex-link port on while it's off.

    And running IR just to turn it on and serial for all the inputs & power off commands would just be a waste. So, if I were you, I'd just jam the flasher up through the metal sheet on the back of the TV if you don't want the flasher on the front of the beautiful looking display.

    Samsung tech support is a joke . . . don't waste your breath.

    I forget which model it is (8000 I think), but the last Samsung I played with you could stick the emitter on the bottom of the TV, behind the front glass overhang. Hidden and easy.

    I haven't had a chance to test it out yet, but there is a power on command listed in the 232 protocol.

    See attached zip file...

    Yeah, but I've been unable to make it to work. I've heard mixed reviews with the LED RS-232 port; some say it works right out of the box and then others with the same exact model say they've had to do something in the service menu, and others just can't get it to work at all (the category in which I fall.)

    IR Control

    Has anyone found discrete power commands for these displays? The remote it comes with just has a power toggle button.

    Power On:
    0000 0059 0000 0022 00D1 00D1 0019 004D 0019 004D 0019 004D 0019 0019 0019 0019 0019 0019 0019 0019 0019 0019 0019 004D 0019 004D 0019 004D 0019 0019 0019 0019 0019 0019 0019 0019 0019 0019 0019 004D 0019 0019 0019 0019 0019 004D 0019 004D 0019 0019 0019 0019 0019 004D 0019 0019 0019 004D 0019 004D 0019 0019 0019 0019 0019 004D 0019 004D 0019 0019 0019 08B1

    Power Off:
    0000 0059 0000 0022 00D1 00D1 0019 004D 0019 004D 0019 004D 0019 0019 0019 0019 0019 0019 0019 0019 0019 0019 0019 004D 0019 004D 0019 004D 0019 0019 0019 0019 0019 0019 0019 0019 0019 0019 0019 0019 0019 0019 0019 0019 0019 004D 0019 004D 0019 0019 0019 0019 0019 004D 0019 004D 0019 004D 0019 004D 0019 0019 0019 0019 0019 004D 0019 004D 0019 0019 0019 08B1

    This is the file that I have been using without issues.

    To give credit where it is due... these were all pulled from the Samsung Discretes 08 remote in the installer generated RTI IR library.

    I found a manual while searching forums. 232 specs start on page 116.

    http://a248.e.akamai.net/pix.crutchfield.com/manuals/305/30561a750.pdf

    I use this protocol for model LN-XX and UN-XX. Uses a header of "$08,$22" followed by 4 bytes, then a checksum(two's complement of the previous). Also, it worked out of the box, and the power on command works.

    Hope it helps!

    Is that for displays with a 9 pin 232 port, or the Ex-Link port?

    Well I guess I answered my own question. I was able to use that protocol on a UN55C6300SF display going into the 1/8" trs Ex-Link jack.
    Pinout was:

    AMX Pin 2 - Tip
    AMX Pin 3 - Ring
    AMX Pin 5 - Sleeve

    Samsung IR on LED TV's

    Working on a project with 4 Samsung LED Displays. I've spent hours trying to get the IR to work on the units. It seems like the emitters only work out of the shell. Any tips or tricks appreciated.

    Samsung TCP Control

    You the man! is working great, where did you get the protocol for that ???
    Could you please post it? I need the power commands and the discrete inputs to implement.

    Thanks for posting this Nate! You saved me from having to dig for it :)
    Here's the rudimentary module I threw together if anyone wants it. It doesn't do much, but it might save someone else a bit of typing. I tested this with a Series 6 650 LCD TV. This tv provides no feedback, not even the success/fail ack described in the manual, but at least all the discrete power and input controls work :)

    I have used these on the Samsung LED and they work well.

    Here are the commands I have received from Samsung

    Anyone seen a more recent protocol doc? Looking for the command to get to the Smart Hub input.

    If the protocol in the ZIP two messages up works at all, you can "find" the input for the new function by just following the pattern of the existing inputs, i.e. add one or the logical next command, and keep trying til you find it.

    Tried that, went on to something else after a fruitless 1/2 hour or so. I'm guessing its not in the same subset as the standard inputs.
