I also changed Control > Sub Option > RS-232 Jack -> Debug ^ Ex-Link Cable (service port TTL serial) https://wiki.samygo.tv/index.php?title=Ex-Link_Cable_for_C/D/E_Series_and_BD_players {image: 800px-TTL-232_E_pinout.jpg} 3.5mm jack "service" on TV: * 1 - tip - Tx * 2 - ring - Rx * 3 - ring - GND If you have TRRR jack, just use first three pins. Others are not connected to anything in TV. To find ground pin check continuity between your jack breakout and USB connector. One you found ground, pins from it towards tip are Rx and Tx. I also measured Rx and Tx pins which where around 3.3V, so safe to connect to usb serial. ^ top-debug menu https://wiki.samygo.tv/index.php?title=Top_Debug_Menu:_TDM |
