RS-232 Parameter - Parity

Parity is an additional digit that makes the number of bits in the ASCII code odd or even. The scanner’s parity must match the host’s parity.

RS-232 Parameter - Data Bits

RS-232 serial communication requires ASCII data to be transmitted in either 7 or 8 data bits. In addition, one parity bit will be transmitted. If necessary, scan the appropriate bar code that matches your host device’s requirements.

Generally, if 7 data bits are selected, 2 stop bits are transmitted. If 8 data bits are selected, 1 stop bit is transmitted . Stop bits are actually just an idle trans- mit line. From the scanners perspective, they are only important if the scanner is receiving more than 1 byte of information at a time. For most applications, the scanner is a transmit only device.
