3-4. Hardware Handshake
This chapter provides the information on the sequence of hardware handshake.
It is based on the presumption that RTS and CTS signals stay at H-level after the initialization.
(1) Sending command from the host system to this scan engine
1) The host system confirms that CTS signal is at H-level
2) The host system shows that there is command data being sent by setting RTS signal to
L-level.
3) This scan engine detects that CTS signal has been changed to L-level and shows that it
is possible to receive the command by changing RTS signal to L- level.
4) The host system detects that CTS signal has been changed to L-level and transmits data
to TXD signal.
5) When transmission of the last data character completes, the host system sets back RTS
signal to H-level.
6) This scan engine detects that CTS signal has been set back to the H-level and sets back
RTS signal to the H level.
(2) Sending data from this scan engine to the host system
7) This scan engine confirms that CTS signal has been set to H-level.
When CTS signal stays at L-level, it is deemed that there is a command being sent from
the host system so that the data transmission shall be cancelled.
8) The decoder transmits the data to TXD signal.
When CTS signal is set to L-level while the data is under transmission, it is deemed that
there is a command being sent from the host system and data transmission shall be
cancelled to prioritize reception of command.
When the data transmission is cancelled to prioritize reception of command, the data
shall be resent after reception of command.
When there is no command being sent from the host system and CTS signal is set back
to H-level, cancelled data transmission shall restart.

3-5. Communication Procedure (example)
This chapter provides the information on the communication procedure between this scan engine
and the host system. The sequence of this procedure is as follows:
(1) Transfer of the command data packet from the host system to this scan
engine
TXD
(Host RXD)
RXD
(Host TXD)
RTS
(Host CTS)
CTS
(Host RTS)
1) The host system sets RTS signal to L-level for the data packet transmission.
2) This scan engine detects that CTS signal has been set to L-level and sets RTS signal to
the L-level.
3) The host system confirms that CTS signal has been set to L-level and starts
transmission of command data packets.
4) The host system sets back RTS signal to H-level after transmission.
5) This scan engine confirms that CTS signal has been set back to H-level and sets back
the RTS signal to H-level.
6) This scan engine sends back responses.
Note: When ACK/NAK protocol is not selected, the sequence of procedure described in 6)
shall not occure. Also, ACK response shall not be sent for the command below. It is a
command to send back the response data from this scan engine.

2) The host system sets RTS signal to L-level for transmission of response to the data sent.
3) This scan engine detects that CTS signal has been set to L-level and sets RTS signal to
L-leve.
4) The host system sends the response.
5) The host system sets back RTS signal to H-level after transmission of the response.
6) This scan engine detects that CTS signal has been set back to H-level and sets back the
RTS signal to H-level.
Note: When ACK/NAK protocol is not selected, it is not necesarry to carry out the sequence
of procedure listed above in 2) to 5).

transmission.
4) This scan engine sets RTS signal to L-level.
5) The host system sets back RTS signal to H-level to restart the data transfer.

2) This scan engine detects that CTS signal has been set to L-level and sets RTS signal to
L-level.
3) The host system confirms that CTS signal has been set to L-level and transmits
command packets.
4) The host system suspends transmission and resets RTS signal to H-level. In this case,
this scan engine does not detect that CTS signal has been set to H-level so that RTS
signal stays at L-level. Therefore, it will continue to be ready for the data packet
reception. Although, the host system needs to restart transmission of data packets within
the setting value of “Host Character Time-out”.
5) The host system sets back RTS signal to L-level.
6) The host system restarts transmission.
7) The host system sets back RTS signal to H-level again after a completion of data packet
transmission.
8) This scan engine detects that CTS signal has been set back to H-level and sets back
RTS signal to H-level.
9) This scan engine sends out the response.
Note: When ACK/NAK protocol is not selected, the sequence described in 9) shall not occur.

H-level so that RTS signal stays at L-level. Therefore, it will continue to be ready for the
data packet reception. However, the host system needs to restart transmission of data
packets within the setting value of “Host Character Time-out”.
4) This scan engine takes time-out of the data packet receiption and sets back RTS signal

3-6. ACK/NAK Protocol and Data Format
(1) Command Data Packets (from the host system to this scan engine)
The command data sent out from the host system shall be in the command packet format
defined separately in this specification.
It is possible to enable or disable ACK or NAK response changing the settings of “Software
Handshaking”.
To configure exact settings, it is recommendable to control transmission of ACK and NAK
responses with “Enable ACK/NAK.
(2) Transmission of Decoded Data (from this scan engine to the host system)
In transmitting decoded data from this scan engine, it is possible to choose between the
packet format and unpacket format.
Also, it is possible to control transmission of ACK and NAK responses by setting ”Software
Handshaking”.
1) Packet Data with ACK/NAK Control
Decoded data will be transmitted in the packet format. (Refer to 4-2-6)
After transmission of the decoded data, this scan engine waits for the response from the
host system.
When the response time for the host system runs out, the host system retries transmission
of responses twice. However, if it fails in transmission after those retrying, transmission is
deemed as error and it discards the response data.
2) Unpacket Data with ACK/NAK Control
This scan engine only transmits the result of decoding (including pre/suffix) and shall not
wait for the response of the host system.
However, the response to the command data packet shall be sent.
3) Packet Data without ACK/NAK Control
Decoded data shall be transmitted in packet format. However, this scan engine shall not wait
for the response of the host system.
4) Unpacket Data without ACK/NAK Control
This scan engine only transmits the result of decoding (including pre/suffix) and shall not
wait for the response of the host system.
