9.6.1
Trigger
When the optical reader receives a character string that is identical to the configured
character string in the WBM, it triggers image acquisition and processing.
9.6.2
Write match string
Note
Sent match string takes effect immediately
A sent match string takes effect immediately. The sent match string is not synchronized with
the trigger signal or the processing of buffered acquired images.
Therefore,
ensure that the match string is sent when no image acquisition is running.
Requirement for matching with 1D/2D codes
All match options ("All", "Position", "ID", "GS1") are supported for 1D/2D codes. The match
string that is sent must be formatted in such a way that the information required for the
match can be extracted.
