For anyone else experiencing the situation where EX-LINK only responds to Power-On, but ignores everything else, the key is to turn AnyNet+ off and Hotel Mode (aka Hospitality Mode) on. So the settings that finally worked for me were: 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 baud --8 bit --no parity --1 stop bit --no hardware flow control

I'm trying to use the EX-Link connection on my Samsung QN7570RAFXZA TV. I can successfully send a power-on sequence, but the TV doesn't respond to any other commands over the EX-Link connection (power off, set source to TV, set source to HDMI1, etc.). Details appear below. Can anyone tell me what I'm doing wrong? Connectivity: 9600 baud, 8 bit, no parity, 1 stop bit, no hardware flow control Configuration: Service Mode settings: RS-232 Jack: UART EXT Link Support: ON USB Serial: ON Hotel/Hospitality Mode: Hospitality mode on or off makes no difference Power-On command sequence: 0x08 0x22 0x00 0x00 0x00 0x02 0xd4 Power-Off command sequence: 0x08 0x22 0x00 0x00 0x00 0x01 0xd5 I also set RS-232 Jack to DEBUG, and received lots of console traffic at 115200 baud (normal for debug mode, but not normal "ON" mode), but it didn't respond to anything I tried to type. This tells me that my connection is good, at least for traffic *from* the TV.
