How to switch to a USB keyboard on AT20Q

We want to connect AT20Q-SM to a PC. However, since we do not have administrator rights, we cannot install the driver. What settings should we use to switch to a USB keyboard?

Connect AT20Q-SM to the USB port of the PC on which Active USB-COM Port Driver is not installed, and press the Trigger Switch for two seconds or longer. The interface of AT20Q-SM will be switched to the USB keyboard.

 

This function is effective when the USB Keyboard Interface Auto-Switching Function has been set to “Enable.”

 

If the driver has been installed on the PC, the above operation does not switch the interface to the USB keyboard.

 

 

This function is effective on the following models.
 
Model Firmware Version
AT20Q-SM/AT21Q-SM Version 1.10 or later
AT25Q-SM/AT26Q-SM Version 1.10 or later
