a) No Handshaking
The scanner attempts the communication regardless of the state of the host
computer.
Figure 9: No handshaking
b) BUSY/READY
The scanner and the host computer notify each other of their state and
whether they can receive data with BUSY/READY through an RTS line. They
can communicate state to each other through a CTS line when connected as
in the following figure.

The scanner stays ON (is able to receive data) except during certain parts of
the process, such as receiving data (buzzer command execution), transmitting
data, and menu processing. The scanner checks the CTS line before
transmitting data. When it is ON, the scanner transmits data. When it is OFF,
the scanner waits for it to turn ON within a set time. The scanner will abort
transmission with an error indication (buzzer) when the CTS line is not ON
within a specified period. The Flow Control time-outs are as follows, and the
default setting is “indefinitely“ (I0).

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 12: 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.
ACK/NAK timeout can be set as follows using the menu or commands.
