System Diagram

Signal Switching

1. Manual Switching Press the SORCE/AUTO-3s button to select the HDMI, DP or VGA source, the corresponding green activity LED will be lighted up.
2. Auto Switching Long-press the SORCE/AUTO-3s button at least 3 seconds to enable auto switching mode, the green activity LED (AUTO) will be lighted up. Press this button again to select next source and exit auto mode.

The auto switching mode abides by the following principles:

• New Input : Once new source is connected, the new source will be automatically switched to input signal.
• Rebooting Device : The PT-PSW-41H has the ability to save the latest configuration before losing power. The switcher automatically enters the mode as latest mode used; moreover, it detects all the inputs and memorizes the connection status for future rebooting use. If the latest displayed signal is still available, the unit will output the signal. Otherwise, the unit will detect all the input signals with priority from HDMI to VGA. When the first signal was detected, it will transfer to output.
• Signal Removing : Once removing the current display signal, PT-PSW-41H will detect all input signals with priority from HDMI to VGA. It will transfer the signal firstly detected to be available to the output device.
