4. Magnetic Switch Adjustment Method
The AULA H108 features magnetic switches that can be adjusted via a dedicated driver. This allows for advanced customization of key behavior.
- Dynamic Keystroke (DKS): Bind 1 to 4 functions to a single button based on the degree of press and release.
- Multi-Point Trigger (MPT): A single button can trigger three different functions at three different depths.
- Press and Hold/Click (MT): Assign two functions to a single button; one for a quick click, another for a press and hold.
- Switching Switch (TGL): Modify a button to trigger continuously when clicked, and normally when pressed and held.
- Release Trigger (END): Send another button command when a key is released.
- SOCD Function: Bind two buttons; pressing the second button will force the release of the first, ensuring only one button is active at a time.
- Quick Trigger Function (RT): Dynamically adjusts trigger and reset stroke based on your intention to press or release.
- Visualized Calibration: The driver allows for visualizing fast magnetic switch travel calibration and real-time detection of magnetic switch travel.
To calibrate magnetic switches:
- Enter the driver software.
- Perform magnetic switch calibration to view the magnetic flux of each switch.
- After starting calibration, press each button until it lights up green.
- Save the calibration settings.
The driver also allows adjusting the keyboard sleep time (default 3 minutes) or disabling sleep. You can set a 0 dead zone for magnetic switch accuracy, and the button delay can be as low as 0.125ms.
