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.
**Space Parity Select this option to make the parity bit always 0.
Even Parity Select this option to make the additional parity bit either a
0 or 1 to guarantee an even number of bits.
Mark Parity Select this option to make the parity bit always 1.
Odd Parity Select this option to make the additional parity bit either a
0 or 1 to guarantee an odd number of bits.
RS-232 Parameter - Data Bits
RS-232 serial communication requires ASCII data to 8 Data Bits
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 ** 7 Data Bits
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.
