End of Read Cycle
New Trigger
Note : When New Trigger is enabled and if not in External Level mode, Laser On/Off will
have no effect. When noreads occur, the laser will remain on.
Timeout or New Trigger
Read Cycle Timeout
Timeout does not function when in Continuous or Level read cycle modes.
Continuous 1 : The scanner will only read a given symbol once until a timeout occurs or a
different symbol is presented.
Note : A minimum setting of 2 is recommended.
Note : Timeout or Timeout or New Trigger under End of Read Cycle must be enabled
for Read Cycle Timeout to take effect.
Usage: New Trigger is an effective way to end a read cycle when objects move
past the scanner at irregular intervals (not timing dependent).
Definition: New Trigger ends the current read cycle and initiates a new one when a
new trigger occurs. New Trigger refers only to a “rising edge” trigger.
With either External Edge , Serial , or Serial or Edge enabled, an edge or
serial trigger ends a read cycle and initiates the next read cycle.
In the case of
External Level , a falling edge trigger ends the read cycle but
the next read cycle does not begin until the occurrence of the next rising
edge trigger.
Usage: Useful in applications that require an alternative way to end the read cycle.
For example, if an assembly line should stop completely or the intervals
between objects are highly irregular.
Definition: Timeout or New Trigger is identical to Timeout , except that a timeout or a
new trigger (whichever occurs first) ends the read cycle.
Usage: It is useful in many tightly controlled applications which require a read cycle
to end before the next object appears and therefore need the flexibility of a
timeout adjustment.
Definition: Read Cycle Timeout is the time span of the read cycle and is represented
in 10 mS increments. It is used in conjunction with External Edge or Serial
Trigger.
Serial Cmd: < K220, end of read cycle, read cycle timeout >
Default: 100 (Corresponds to one second or 1000 mS.)
Options: 0 to 65535. (Divide any positive number entered by 100 to determine the
time in seconds.)
