c) CTS, TXD signals timing
When the CTS line (RTS signal on the host side) is turned off during a TXD signal
transmission, the scanner transmits one charactersand waits. When the CTS signal is turned
on during a character transmission, the character will be transmitted.
Note: When loopback (wire connection) is used for RTS, CTS line of the scanner in
this setting, No handshake is not enabled.
d) MODEM
The scanner's RTS is OFF as soon as power is supplied to the scanner. The scanner will
turn RTS ON when it wants to transmit data to the host. The host should respond by putting
CTS ON when it is ready to receive data. While CTS is ON the scanner is allowed to transmit
data. When all data has been transmitted, the scanner will turn RTS OFF. In response, the
host should turn OFF the scanner's CTS. If, while RTS is ON, the CTS line is not ON for a
certain configurable period, the scanner will terminate the transmission with an error
indication of the buzzer.
