The protocol supports daisy-chaining of serial devices. Supports one TV or projector per thing, also corresponding to a unique serial port. See below for a list of supported channels. are all there.This binding can send some commands typically used by LG LCD TVs (and some used by projectors). You can assign Set ID numbers if you have multiple panels but the first 00 tells what ever is connected that ALL sets are to do the following command.Įvery commmand that exists on the remote has a code so changing input, volume, mute etc. Open the terminal window then type the following. The settings for whatever client you use are as follows. I am using a Null Modem cable ( it is called crossed in the LG manual ) £1.50 delivered from eBay. This worked for me on an LG 32LH3000 so no reason why it would not work for the many other LG panels etc.Īll of the codes are in the LG manual right at the back this is available from the LG website and came on a CD rom as packed with the panel itself. Old thread but as I found it earlier whilst looking for a solution, I thought I would update it having got this working. Sometimes this is because the connection settings aren't quite right (in which case you can only experiment, by selecting slower baud rates - though the 8,n,1 settings are pretty consistent), or the RS-232 connection is designed more for engineers and repairers who will know what do do with the connection because they have a service manual.

Alas, not all devices will give you an positive response to acknowledge what you are doing - or in some cases wont give you a response if the command you are entering is incorrect, it will only acknowledge properly formatted commands. From there it's a case of entering the commands you have at your disposal to see what happens.īeyond this, I'm not sure there's any more I can advise you on if the instructions for this TV aren't obvious. Hit the enter key a couple of times and see if anything happens.

After you connect to a serial device it is often necessary to 'wake it up' - that is when you connect, the terminal client will say that you are connected, but you find yourself staring at a blank screen. The terminal client (like Tera Term) will present you with fields to complete for these settings after which there will be a 'connect' option (or similar). (9600 baud, 8 data bits, no parity, 1 stop bit) These settings will often be presented in a format like this:. When connecting to a device which has a serial (RS-232) port, not only should there be instructions relating to the commands it supports, but also the appropriate settings for establishing a connection (baud rate, data bits, parity, stop bits and, on occasion, flow control). I think you'll find a google search for 'Tera Term' will give you what you need.
