RS232 Command for LG TV Not Working

Get Help
1

I have already read the https://xibo.org.uk/docs/setup/command-functionality but it doesnt work.

When i connect my LG TV to my Windows Client (Serial, COM1), which runs the XIBO Player i can control the TV via Putty without any Problems with this Commands: https://support.justaddpower.com/kb/article/36-lg-rs232-control/

I have a Problem when i put the command into a Shell Command - i put this command in the Field “Windows Command” - rs232|COM1,9600,8,None,One,None,1|6B 61 20 30 30 20 30 31 0D

Why doenst work this on my Windows 10 client?

Thank You,
Thomas

Hi Thomas,

I know this is almost 12 months later, but the way I got RS232 commands to work on my displays is by running a powershell script on the local computer that controls the TV.
.

  1. Make sure the times are correct (one of my displays was off on time and this prevented sending RS232 commands to work).
  2. I used Xibo to execute a powershell script. Using ( PowerShell -NoProfile -ExecutionPolicy Bypass -File “C:\TurnTvOff.ps1” ) to run my command (bypassing the execution policy is crucial because the script is unsigned).
  3. The script (stored on the C drive of my displayI used was:
    $port=new-Object System.IO.Ports.SerialPort COM4,9600,None,8,one
    $port.open()
    $port.WriteLine(“ka 01 00`r”)
    $port.Close()

for the port you’ll need to use what your PC has (COM1 like you said). “ka 01 00 `r” is for LG tv’s power off.

Hope this helps, I’ve been using it on many of my displays and it works well.
