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 imager expects either an ACK or NAK

response from the host. When a NAK is received, the 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 imager

issues an error indication and discards the data.

The imager waits up to the programmable Host Serial Response Time-out to receive an ACK or NAK. If the

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 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 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 imager transmission off until the imager receives an XON

character. There are two situations for XON/XOFF:

•XOFF is received before the imager has data to send. When the 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 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 imager receives an XON character, it sends the rest of the data message. The imager waits

indefinitely for the XON.
