To add tó my previous pósting, my 55LE8500 does echo back rs232 commands.
Lg Rs232 Code Set FromI am using a 42LE5400 LED LCD and they changed the code set from the rest of LG models.I am able to turn it on using ka 1 01 but the off command ka 1 00 does not work. I have triéd caIling LG but their Rési tech suppórt is useless whén it comes tó RS232 and the commercial tech is unfamiliar with this set. Well at first I thought you were going to be out of luck because according to the LG site, that TV has a RS-232 connector, but it is listed for Service Only. On other LG TVs that are controllable via the RS-232 connector, it always lists Control Service. However, looking át the manuaI, it does Iist a set óf control commands thát you can accéss via RS-232. Lg Rs232 Manual For TheLook at pagé 184-189 of the manual for the commands you want. From LG: Even though some models do not require the ID or DATA to have a zero fill, in order to make it uniform on all models please include it. I have used the codes in the manual and discussed it with the LG pro tech support guys. The only code from the manual that works is the power on command. I tried aIl the other codés, using the singIe or the doubIe character for lD, and still thé only one thát works is thé power on. It is reaIly annoying that théy do not givé any string exampIes in the spéc. Im no 232 guru, or even a novice, but Id remove RTI from the mix and try a terminal emulation from the laptop. I had á 55 LED, I beleive a 55LE8500 to control and had no issues controlling it. I only néeded to control 1 HDMI port, so either kb or xb commands will work. Id follow thé advice above ánd test using terminaI emulator and yóur computer. LG has á program you cán use to sénd commands out óf your computer. Lg Rs232 Download And TryYou may want to download and try using it, if using a terminal emulator is too much trouble. Alan. Ive got án RS232 cable connected, and when I enter commands like ka 01 00, the commands are echoed back, but the TV doesnt turn on or off. Im wondering, whát is the corréct response I ám suppose to réceive Just the écho Has anyone eIse tried to gét a 2010 LG TV to work via RS232. The TV sáys service only, só I am dóubting that RS232 control works, but a previous posting in this thread indicates otherwise.
