3.2
Reading Timeout Mode
Code Reader reads the symbol repeatedly during the duration time, set by “TOTALLIM” after
the SYNC input, or continues reading until the decoding is successful. If the reader cannot
decode successfully in the duration time, it stops reading and sends an error code to the host.
Typically MAXIMG is set to a number greater than one. The multiple MAXIMG enables the
Cycle Buffer Function and the simultaneous parallel processing between image import and
decoding. This may shorten the processing time.
The timing charts below are drawn referring to the enabled cycle buffer function.
