Set Uart Port Data Bits, Stop Bits And Parity - Waveshare Barcode Scanner Module B Setup Manual

SET UART PORT DATA BITS, STOP BITS AND PARITY

Data bits: 7, 8-bit data bits can be selected for transmission. The terminal must be set to the same
data bits as the barcode scanning device in order to communicate properly. Default = 8.
Stop Bit: The stop bit can be set to 1 or 2. The terminal must be set to the same stop bit as the
barcode scanning device for proper communication. Default value = 1.
Parity: The method to check the character bit mode, E is even parity, O is odd parity, N is no parity
bit, and the terminal must be set to the same parity bit as the scanning device for normal
communication. Default = N.
