Serial Port Connection

All communication parameters between the scanner and terminal must match for correct data transfer through the serial port using RS-232 protocol. Scanning the RS-232 interface bar code, programs the scanner for an RS-232 interface at 9600 baud, even parity, 7 data bits, 1 stop bit (8 bit data), and adds a suffix of a CR LF.
