Product Reference Guide 291Chapter 6ReferencesThis section contains explanations and examples of selected barcode features. See theConfiguration section for the actual barcode labels used to configure the reader.RS-232 ParametersRS-232 OnlyBaud RateBaud rate is the number of bits of data transmitted per second. Set the reader's baud rate tomatch the baud rate setting of the host device. With an improper baud rate setting, data maynot reach the host correctly.Stop BitsThe stop bit(s) at the end of each transmitted character marks the end of transmission of onecharacter and prepares the receiving device for the next character in the serial data stream. Thenumber of stop bits selected (one or two) depends on the number the receiving terminal isprogrammed to accommodate. Set the number of stop bits to match host device requirements.ParityThis feature specifies parity required for sending and receiving data. A parity check bit is themost significant bit of each ASCII coded character. Select the parity type according to hostdevice 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 anodd 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 aneven number of 1 bits are contained in the coded character.Handshaking ControlThe data interface consists of an RS-232 port designed to operate either with or without thehardware handshaking lines, Request to Send (RTS), and Clear to Send (CTS). HandshakingControl includes the following options:• RTS — RTS is asserted during transmissions. CTS is ignored.• RTS/CTS — RTS is asserted during transmissions. CTS gates transmissions.
