Notes on Hotkeys:
- "++" indicates pressing a key twice in rapid succession. For example, [Scroll] ++ [Scroll] + [1] means pressing the Scroll key twice rapidly, then pressing the number '1' key. A 2-second timeout exists between hotkey codes; pressing Scroll again after more than 2 seconds invalidates the combination.
- 'n' can be 1, 2, or 3. For example, "Scroll ++ Scroll + S + 1 + 2 + 0" sets the polling time interval to 120 seconds.
- When automatic detection is enabled, the switch monitors USB interface connections. It automatically switches to a newly connected computer or switches away if a USB interface disconnects. If an inactive computer's USB disconnects, it does not switch. If both automatic detection and polling scan are active, unconnected USB computers are skipped.
- 'CTRL' and 'SHIFT' can be either left or right keys.
- [Ctrl + Shift + 1] requires holding CTRL and SHIFT while pressing '1', then releasing all keys.
- By default, the pass-through USB port synchronization matches the keyboard and mouse switch. If this synchronization is turned off, the pass-through USB port remains on the original PC unless a specific hotkey is used to switch it independently.
7.3 Auto Cycling Mode
To turn the auto cycling mode ON or OFF, double-click "Scroll" or "Num" or "Caps" followed by "S". The default switching interval is 5 seconds. Press "ESC" to exit. Users must select the mode (Scroll, Num, or Caps) based on the currently active mode.
