LG TV Control

So after doing some research on TVs and automated control, I purchased a 37" LG LH30 Series TV for my MBR about 6 months ago. I choose to go with the LG because it has a native RS-232 port with a easily attainable protocol - found in the owners manual :( I mounted that TV shortly after I bought it and still havent run any additional wiring to that area to support installation of a serial cable.

All of that said... I just bought a 42" LG LH40 Series TV for our guest BR, and wanted to play with some of the serial commands before I mount it. I just started looking through the manual and found some information which led me to begin thinking about how I would actually wire and install the serial cabling to a PC.

The LG manual states that you need to assign each TV a Set ID (from 1 - 99), were additional TVs would obviously have a different SetID:

There are also examples of various commands in the manual such as Power On/Off:

Which leads me to the question.. since the command requires the specific SetID of each TV, do you guys think that I could potentially wire BOTH TVs to the same serial port?
 
I believe that the LGs are intended to allow multiple sets on a single port, each with a unique ID. If you're just wiring each set to its own port then there's no need to change the default ID from "1".

That was my understanding as well. I suppose I will have to try it out to be sure. Thanks for the response.
 
Your thinking is correct, not that I have put it into practice though.

The concept was that you could have multiple Sets on the same port and then control any of them (or all if set ID 0 is used I think).

Now if serial ports are light on, then you can do this, but you need to make up an adapter to split the serial port etc.

It is much easier to wire up each TV to its own serial port.
