UN75J630D RS232 Control

Post by joltman » Thu Jul 04, 2019 12:11 am

I've been beating my head against a wall all day trying to get this working. I've got my 3.5mm stereo (TRS) adapter hooked up to my laptop via DB9 cable and USB/Serial adapter. If I get into the SERVICE MENU on the TV, I can change the UART MODE to DEBUG and see the debug output but no input. If I change it to ANYTHING else, I get no input or output.

I'm trying to control this TV via RS232. Is this even possible? What the heck am I missing? I've tried setting the UART port to FANET, UART, DEBUG, nothing seems to let me send commands. Thanks for the assistance!
