Does anyone know if there are volume up and down serial commands for LG? I have the 0-64 (volume 0-100) but was wanting to control the TV volume with a T2C and XP-8 using the repeat until button is released command.

I just flipped thru a couple of manuals and found the same thing you did. Seems like an odd thing to leave out.

It might depend on the model, but LG should support IR key emulation commands in the form "[m][c][ ][Set ID][ ][Data][ ][Cr]" where Data is the IR hex code for your particular function (should be a table for these in the manual).

Volume Up would be "mc 00 02 \r" and volume down would be "mc 00 03 \r" (in a Crestron world) for 32LX1D.

Well, I guess tdogny was on it then.......

Thanks for the info! I don't know why it's not available in any of the manuals.

I had a hard time getting the channel+ and - about a year ago. I was in touch with an engineer at LG back and forth for a few days. He sent me many files for RS-232 and none contain these commands.

Once again,Thanks!

Even with protocols that have discrete values ( 1d-100d-0h-64h) that do not have discrete volume up/down commands can be coded to generate discrete volume up/down--I imagine even with pseudo control systems like RTI. The idea would be for the button press to cycle through the discretes, one unit at a time, in this case from 1-100d.

It's rather simple line code and in Simpl, it's a tad more complex but not very difficult.
