CTS, TXD signal timing
When the CTS line (RTS signal of the host) is turned OFF while sending a TxD signal,
the scanner transmits one character and waits. When the CTS signal is turned ON while
transmitting a character, the character will be transmitted.
Figure 14: Signal timing
Note: When using loopback (wire connection) for RTS, CTS line of the scanner in this
setting, No handshake is not enabled.
c) MODEM
The scanner turns CTS line ON before transmitting data. Other processes are
the same as BUSY/READY.

d) ACK/NAK
After data has been transmitted, the scanner expects to receive one of the
following responses from the host:
ACK response—Action: The scanner completes transmission with the good-
read buzzer and returns to the initial state.
NAK response—Action: The scanner sends the data again and waits for the
response from the host.
DC1 response—Action: The scanner returns to waiting for the trigger, if it has
a trigger (the initial state).
None response—Action: The scanner sounds the error buzzer and returns to
the initial state.
