CHAPTER III INTERFACE TYPE
Barcode Scanner Module (B) supports two communication interfaces, USB port and UART serial
port.

UART INTERFACE

SETTING UART INTERFACE

To use the UART interface, you need to connect the serial module or connect the UART interface
directly. Scan the following setup code to set it as UART output. The default configuration of the
UART port is 115200 baud rate, 8 bits of data, no parity bit, 1 bit of stop bit, and carriage return
line feed added by default.

SETTING UART PORT BAUDRATE

The baud rate allows the module to send data from the Barcode Scanner Module (B) to the
terminal at the specified rate. In use, the baud rate of the terminal must be set to be the same as
the baud rate of the Barcode Scanner Module (B) for proper communication. The default setting is
115200.
