IP is flakey and unreliable on the Frame.I now have a functional solution on the Frame 2022 using RS232 which I've chosen for two reasons. Hey all, thanks for this wonderful thread, and thanks Duct Tape for the list of commands. If you can think of any thing that could be causing the total disconnect, please let me know. To summarize, we have not been able to get ANY command successfully via Serial-USB to any of the TVs. When testing a direct serial connection from a laptop (with a USB to Serial dongle) and the Hercules utility, all we is 'double-quotes' when we send the HEX codes from the XLS shared here for power-on, power-off or power-toggle. Service Mode settings: -RS-232 Jack: UART -EXT Link Support: ON -USB Serial: ON Hotel/Hospitality Mode: OFFĮX-Link com port settings: -9600 baud -8 bit -no parity -1 stop bit -no hardware flow control We use a GlobalCache iTack IP2SL gateway (has a DB9-M port) to connect to TTL cable. We are using a standard RS-232 cable (USB to DB9-F with a PL chip). We have tried all the suggestions in this thread with regards to getting USB Ex-Link working but we get no PowerOn or PowerOff or any command executed at all. IR is supported but it's the less desirable option. This leaves Serial control as a limited-reliable solution (no feedback as far as I know). Kramer tells us Samsung and LG have gone the authentication route and they cannot support yet IP control.

We use Kramer AV Controls to design our iPad custom programming. All of these TVs no longer have the 3.5mm Ex-Link port we were expecting to have.įrom a communication from Samsung we understood USB was needed for control now, but Samsung buried the 'USB Serial' setting in the service menu. I have an installation that involves a few TVs of the following models: UN65TU8000FXZA (TU8000s of different sizes) and a QN85Q60TAFXZA.

I can say Samsung makes great TVs but there is a lot to desire with regards to its support.

Thank you all for putting this together and contributing to it.
