RS-232 INTERFACE 4 - 13
Software Handshaking
This parameter offers control of the data transmission process in addition to, or instead of, that offered by
hardware handshaking. There are five options.
If Software Handshaking and Hardware Handshaking are both enabled, Hardware Handshaking takes
precedence.
• None: When this option is selected, data is transmitted immediately. No response is expected from host.
• ACK/NAK: When this option is selected, after transmitting data, the linear imager expects either an ACK
or NAK response from the host. When a NAK is received, the linear imager transmits the same data
again and waits for either an ACK or NAK. After three unsuccessful attempts to send data when NAKs
are received, the linear imager issues an error indication and discards the data.
The linear imager waits up to the programmable Host Serial Response Time-out to receive an ACK or
NAK. If the linear imager does not get a response in this time, it issues an error indication and discards
the data. There are no retries when a time-out occurs.
• ENQ: When this option is selected, the linear imager waits for an ENQ character from the host before
transmitting data. If an ENQ is not received within the Host Serial Response Time-out, the linear imager
issues an error indication and discards the data. The host must transmit an ENQ character at least every
Host Serial Response Time-out to prevent transmission errors.
• ACK/NAK with ENQ: This combines the two previous options. For re-transmissions of data, due to a
NAK from the host, an additional ENQ is not required.
• XON/XOFF: An XOFF character turns the linear imager transmission off until the linear imager receives
an XON character. There are two situations for XON/XOFF:
• XOFF is received before the linear imager has data to send. When the linear imager has data to send,
it waits up to Host Serial Response Time-out for an XON character before transmission. If the XON is
not received within this time, the linear imager issues an error indication and discards the data.
• XOFF is received during a transmission. Data transmission then stops after sending the current byte.
When the linear imager receives an XON character, it sends the rest of the data message. The linear
imager waits up to 30 seconds for the XON.
