Serial Data
The scanner accepts an ASCII character from the host or controlling device as a trig-
ger to start a read cycle. Serial data trigger behaves the same as External Edge.
Serial Data & External Edge
The scanner accepts either an external trigger or a serial ASCII command to start a
read cycle.
When to Output (bar code data)
Default:
As Soon As Possible
Options:
As Soon As Possible, End of Read Cycle
Allows you to choose when bar code data is sent to the host.
As Soon As Possible
Causes bar code data (good reads) to be transmitted immediately upon a good
decode.
End of Read Cycle
Causes bar code data to be transmitted at the end of the read cycle.
Subsequent rising edge trigger
Object # 2, moving in front of the detector's beam, causes
a second trigger (rising edge trigger) signal to be sent to
the scanner. This signal initiates a new read cycle
and
ends the previous read cycle
provided
that New Trigger or
Timeout and New Trigger is enabled and a good read or
timeout has not already occurred.
