Auto Switching
The auto switching function can be enabled/disabled via the AUTO button on the front panel, IR remote or the RS-232 commands. It is enabled by default.
Restore Factory Defaults
Press and hold the Switch and eARC buttons for 3 seconds simultaneously to reset this switcher. At this time, all LEDs (except for the power LED) on the front panel are flashing twice. After completed, all setting are restored to factory defaults.
There are two auto switching modes: TMDS detection and 5V detection. And the default is TMDS detection. It can be set via RS-232 commands.
TMDS detection
- If an IN port is connected, it will switch to the port when the TMDS/FRL signal is detected, and the corresponding LED will light up.
- If the current input port is disconnected or in standby mode, and no signal is detected, it will switch to the next active port automatically. If there are no other active ports, it will stay at the current port.
5V detection
- If one IN port is connected, and the others are connected later. It will switch to the lastest one automatically (last in gets priority) as the input channel, and the corresponding LED will light up.
- If the four IN ports are connected meanwhile, when one of them is disconnected, it will switch to the next IN port automatically according to the order of IN 1~4.
- If only one IN port is connected, it will not automatically switch to the others when disconnected.
