I did read the manual on a few models and the control is via RS232, not Ethernet so let's go forward with revealing an Ethernet to RS232 module. https://www.amazon.com/USR-TCP232-302-Serial-Ethernet-Converter-Support/dp/B01GPGPEBM/ for example.
My background uses so much RS232 and now Bluetooth to RS232 as my software sets up industrial controls as well as testing products on final assembly.
The biggest complaints I see on such is "lack of support." And that's not really the issue. When you get into this area you either code up what you want, learn terminal apps, commands, scripts and so on or you outsource the solution.
I don't expect such things to arrive with a GUI app that does what we want.
In my organization I have 22SM3D, 32LV761H, 43LV761H, 49LV761H, 55LV761H, 32M5KD, 55SM5KD.
All of them comes with the ethernet port.
Can we control those tvs by one standalone workstation?
or If there any other ways beside using the ethernet port.
Thanks in advanced.
