Notes on Hotkey Usage:

"++" indicates pressing a key twice in rapid succession. For example, [Scroll] ++ [Scroll] + [1] means pressing the Scroll key twice quickly, then pressing the number '1' key. The detection timeout between hotkey codes is 2 seconds.
"n" can be 1, 2, or 3. Example: "Scroll ++ Scroll + S + 1 + 2 + 0" means pressing Scroll twice, then 'S', then '1', then '2', then '0' to set the polling interval to 120 seconds.
When auto-detection is enabled, the switch automatically detects USB interface connections and performs smart switching. If a new computer connects, it switches to it. If a connection is lost, it switches to the next available computer. If auto-detection and auto-polling are both on, unconnected USB computers are skipped.
"CTRL" and "SHIFT" can be used with either the left or right key.
[Ctrl + Shift + 1] means pressing and holding CTRL, then pressing and holding SHIFT, then pressing '1', and finally releasing all keys.
By default, the pass-through USB port synchronization matches the keyboard/mouse switch. If this sync is disabled, the pass-through USB device stays on its original PC unless switched independently.

7.3 Auto Cycling Mode

To turn Auto Cycling Mode ON or OFF, double-click "Scroll" or "Num" or "Caps" + "S". The default switching interval is 5 seconds. Press "ESC" to exit. The user must select the mode (Scroll, Num, or Caps) based on the currently active mode.

[Scroll] + [Scroll] + [S]
[Num] + [Num] + [S]
[Caps] + [Caps] + [S]

7.4 RS232 Control
