Read Cycle
End of Read Cycle
End of Read Cycle Mode
Note: When operating in Continuous Read or Continuous Read 1 Output, the reader is
always in the read cycle.
Timeout
Definition: The read cycle is the time during which the reader will attempt to capture
and decode a symbol. A read cycle can be ended by a timeout, a new
trigger, or by the last frame in a capture sequence or a combination of the
above.
Serial Cmd: <K220,end of read cycle,read cycle timeout>
Default: Timeout
Options: 0 = Timeout
1 = New Trigger
2 = Timeout or new Trigger
3 = Last Frame
4 = Last Frame or New Trigger
Usage: Typically used with Serial Data or External Edge and Continuous Read
1 Output.
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 symbol appears, giving the system extra time to decode
and transmit the data to the host.
Definition: Timeout ends the read cycle, causing the reader to stop reading symbols
and send the symbol data or No-Read message when the time set in
Timeout
elapses (times out), if When to Output is set to End of Read Cycle.
If in Continuous Read 1 Output, a timeout initiates a new read cycle and
allows the same symbol to be read again.
With External Edge, Serial Data, or Serial Data or External Edge
enabled, a timeout ends the read cycle and symbol data or a No-Read
message is sent to the host.
With External Level enabled, the read cycle does not end until the falling
edge trigger occurs or a timeout occurs. The next read cycle does not begin
until the next rising edge trigger.
