New Trigger
Usage: New Trigger is an effective way to end a read cycle when objects move
past the reader 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.
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
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.
Read Cycle Timeout
Usage: 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 repre-
sented in 10 mS increments. It is used in conjunction with External
Edge or Serial Trigger.
Serial Cmd: <K220,end of read
Default: 100 (Corresponds to one second or 1000 mS.)
Options: 1 to 65535. (Divide any positive number entered by 100 to determine the
time in seconds.)
Timeout does not function when in Continuous or Level read cycle modes.
Continuous 1: The reader 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.
