3-4 RS-232 interface
Flow control:
None-The communication only uses TxD and RxD signals without any hardware or software
handshaking protocol.
RTS/CTS- If the image platform wants to send the barcode data to host computer, it will issue the RTS
signal first, wait for the CTS signal from the host computer, and then perform the normal data
communication. If there is no replied CTS signal from the host computer after the timeout duration, the
image platform will issue an error indication. By setting (Host idle: Low RTS) or (Host idle: High RTS),
the image platform can be set to match the Serial Host RTS line.
XON/XOFF- An XOFF character turns the image platform transmission off until the image platform
receives an XON character.
ACK/NAK- After transmitting data, the image platform expects either an ACK (acknowledge) or NAK
(not acknowledge) response from the host. When a NAK is received, the image platform transmits the
same data again and waits for either an ACK or NAK. After three unsuccessful attempts to send data
when NAKs are received, the image platform issues an error indication and discards the data.
Inter-character delay: Refer to Inter-character delay of
Response delay: This delay is used for serial communication of the image platform when it waits for a
handshaking acknowledgment from the host.
