Configuration section for the actual barcode labels used to configure the reader.
RS-232 Parameters
RS-232 Only
Baud Rate
Baud rate is the number of bits of data transmitted per second. Set the reader's baud rate to
match the baud rate setting of the host device. With an improper baud rate setting, data may
not reach the host correctly.
Stop Bits
The stop bit(s) at the end of each transmitted character marks the end of transmission of one
character and prepares the receiving device for the next character in the serial data stream. The
number of stop bits selected (one or two) depends on the number the receiving terminal is
programmed to accommodate. Set the number of stop bits to match host device requirements.
Parity
This feature specifies parity required for sending and receiving data. A parity check bit is the
most significant bit of each ASCII coded character. Select the parity type according to host
device requirements.
•
Select None when no parity bit is required.
•
Select Odd parity and the parity bit value is set to 0 or 1, based on data, to ensure that an
odd number of 1 bits are contained in the coded character.
•
Select Even parity and the parity bit value is set to 0 or 1, based on data, to ensure that an
even number of 1 bits are contained in the coded character.
Handshaking Control
The data interface consists of an RS-232 port designed to operate either with or without the
hardware handshaking lines,
Request to Send
(RTS), and
Clear to Send
(CTS). Handshaking
Control includes the following options:
•
RTS — RTS is asserted during transmissions. CTS is ignored.
•
RTS/CTS — RTS is asserted during transmissions. CTS gates transmissions.
