FACTORY DEFAULT

When the RTS/CTS Hardware Handshaking option is selected, the RTS (request to send) and CTS (clear to send) signals will be issued before normal data communication. This option is very helpful to ensure the reliability of data communication.

When the ACK/NAK Software Handshaking option is selected, the scanner waits for an ACK (acknowledge) or NAK (not acknowledge) from the host computer after each data transmission. If the NAK is received, the scanner will re-send the data until receiving ACK.

The Time Out Control is a pre-defined delay time for the scanner to wait for handshaking, acknowledgment, or non-acknowledgment from the host computer.
