RS 232 codes for LG LCD's

Can someone verify that these are the correct hex codes for the LG tv's for the DMPs?

On = 6b612030312030310d

Off = 6b612030312030300d

I can't seem to get them to work and I'm sure that we are using a Null modem cable.

Thanks!

RS 232 codes for LG LCD's

I was able to use the predefined TV control for a Cisco 32N display to turn the LG display on and off.  I did however need to create a custom command for switching to and from the HDMI and cable IN.  The hex commands for those are below.

rs232.tx_hex=6b622030312030300D

rs232.tx_hex=6b622030312030320D

Your commands look very similar so I will assume they are correct.

Did you run the 'RS-232: Control supported, non-DMTech display' advanced task on the DMP prior to this command?

After running the on command, run a status on the DMP in question, look for the lines starting with rs232 and see what the rs232.tx_hex is set to, should be your on command regardless of if it worked or not.  I usually copy the status result to a notepad, easier to look through and your can use the find command.

Good luck
