I'm still experiencing issues getting any command through Serial-to-USB as i my Post 94. Today I'm testing on a new Samsung UN65TU8000FXZA. Similar to one I tested before. No luck. I can't believe this is not even working for Power On.
What am I doing wrong?
My settings are the same as above:
Service Mode settings: --RS-232 Jack: UART --EXT Link Support: ON --USB Serial: ON Hotel/Hospitality Mode: OFF
Standard settings: --AnyNet+: OFF
EX-Link com port settings: --9600 or 115200 baud --8 bit --no parity --1 stop bit --no hardware flow control
you tried reversing the Tx and Rx pins on your cable? That's the first thing I do when things should be working, but are not.
