End of Read Cycle
Note: When to Output must be set to End of Read Cycle before this command can
be active.
End of Read Cycle Mode
Note: When operating in Continuous Read or Continuous Read 1 Output, the scan-
ner is always in the read cycle.
Timeout
Definition: The read cycle is the time during which the scanner will attempt to read
and decode a bar code symbol. At the end of a read cycle the scanner
stops reading symbols and sends the symbol data or noread message to
the host.
Definition: A read cycle can be terminated by a new trigger, a timeout, or a combina-
tion of both.
Serial Cmd: < Khend of read cycle mode ,read cycle timeout>
Default: Timeout
Options: 0 = Timeout
1 = New Trigger
2 = Timeout & New Trigger
Usage: Typically used with Serial or Edge and Continuous One.
It is effective in highly controlled applications when the maximum length
of time between objects can be predicted. It assures that a read cycle
ends before the next bar coded object appears, giving the system extra
time to decode and transmit the data to the host.
Definition: Timeout ends the read cycle when the time set in Timeout elapses or
“times out.”
If in
Continuous Read 1 Output, a timeout initiates a new read cycle
and allows the same symbol to be read again.
With either
External Edge, Serial Data, or Serial Data & Edge
enabled, a timeout ends the read cycle and symbol data or a noread mes-
sage is sent to the host.
With
External Level enabled, the read cycle does not end until the fall-
ing edge trigger or a timeout occurs. The next read cycle does not begin
until the next rising edge trigger.
