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 require-
ments.
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 transmis-
sions.
• RTS/XON/XOFF — RTS is asserted during transmissions. CTS is ignored.
XON and XOFF gate transmissions.
• RTS On/CTS — RTS is always asserted. CTS gates transmissions.
RTS/CTS Scan Control — RTS is asserted during transmissions. CTS gates
transmissions and controls enable and disable state of scanner.
