External Trigger Mode
Code Reader reads the symbol repeatedly during the SYNC input is active. 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.
