```{note}
Connect to the computer and scan the [USB Keyboard](#usb-keyboard) barcode to configure the scanner to keyboard mode.
In the application software environment where the serial port is required, scan [USB Serial Port](#usb-serial-port) and it will be identified as USB COM type, requiring the user to install the driver (the default configuration of this barcode is: 115200 baud rate, 8 data bits, no parity bit, 1 stop bit).
