Thanks, Duct Tape. I'll keep checking back.

sorry, slipped my mind.

I can't seem to get the power on working. Anybody remember the magical settings? The Eco power settings are all off. The service menu settings look ok, to me.

I am working with ES71000 class. A couple years old.
I was able to do power off and input selections via rs232 when I left it
Thanks

Check the Power On Option. Change it from Last Option to Power On. 
...Hope it helps.

By the way, that one works great. Nice document...thanks for the taking the time to make it.

It sure does, perfect timing as well.
On hide sight, probably self inflicted. I didn't think I had to mess with hotel mode because uart setting was outside of that and already working.

I didn't see the setting you mentioned but changed the hotel setting and it was hidden under there.

Thanks!

I hate to revive a more or less dead thread but does the OP know what the responses back from the TV mean? I get a three byte response when I send a command and I can't find any documentation as to whether there is any important information in it or whether it's just a command ok response.

it just means that the command was received I believe.  the tv doesn't provide useful feedback.

thats what i figured. i wish they actually responded with a status that was useful.

Will Samsung TVs send device status updates (like input change) to the controller if input/power is changed manually or through the remote?

Hello Duct Tape i was able to download your excel sheet and i was wondering i am trying to control an ME55A and when i input the hex values from the Samsung manual nothing happens i am pretty new at this so any guidance you could offer would be much appreciated.

Hi all

Just wondering if any of my Australian counterparts have ever managed to get RS232 control working on Australian shipped LCDs? Ive got a Samsung UA55ES8000 which has no ex-link port on it, only a service port. Have measured voltage and get back around 3v (TTL) which leads me to believe its not an rs232 port. Have tried getting comms through my crestron system and im 100% im doing eveything right in terms of code/serial settings/pinouts etc. Just no comms.

Is it possible that samasung australia dont utilise this port? It does have the options for RS232(UART) in the service menu. Just no talky! Have a mate who is a samsung service tech and even he cant get an answer for me!!! His boss actually had to ask him what RS232 was. lol

The code from the TV includes "030cf100" if the action was a success. It may include other characters. I have created a Python script that works great.

#!/usr/bin/env python
import time, serial
ser = serial.Serial(port='/dev/ttyUSB0', baudrate=9600, timeout=1)
resp=""
loop="true"
string="030cf100"
while loop:
        if string in resp:
                print "found it"
                break
                ser.close()
        else:
                ser.write("\x08\x22\x00\x00\x00\x02\xd4")
                data = ser.read(24)
                resp=data.encode('hex')
                print resp
                time.sleep(1)
print "finished"

This will toggle. You can change the hex code ser.write("\x08\x22\x00\x00\x00\x01\xd5") for OFF only. I can not get the ON only code to work. It toggles.

This will try again and again until the TV responds.

Hi,

I'm working with some Samsung LFD, namely ME40A, that I'm trying to turn on and off over rs232.

Here's the manual:
[Link: downloadcenter.samsung.com]

I can figure out how to format the string in python. This is what I've tried.

import time
import serial

STAT = "\xAA\x11\x01\x00\x12"
ON = "\xAA\x11\x01\x01\x01\x14"
OFF = "\xAA\x11\x01\x01\x00\x13"

ser = serial.Serial(
        port='/dev/ttyUSB0',
        baudrate=9600,
        parity=serial.PARITY_NONE,
        stopbits=serial.STOPBITS_ONE,
        bytesize=serial.EIGHTBITS,
        xonxoff=False,
        timeout=1

)

#ser.open()
#ser.isOpen()

ser.write(STAT)

Any ideas on how to format the string? It's a daisy chain of rs232 with ID set on the monitors.

Hello Guys, I have a question about the Samsung LFD Controlling. Because i want to control them with Volume decrement and increment and not with an absolut value. Is that possible? In the manuals is no command about that documented. I don't think that the /08/22... Codes will work for me cause all the Codes from the manuel begin with /AA/...

Thanks for reply :)
