Transition Counter

Used for both AGC and symbol detection routines (see
8-10 and "Minimum Bar Transitions" on page 7-13.
Definition: During the read cycle, the scanner counts the number of bar and space
transitions that have been defined in the Transition Counter Thresh-
old. If the count matches or exceeds the threshold, the scanner will
perform AGC routines.

send a <K505?> command.
Serial Cmd: <K505, transition counter
Default: Disabled
Options: 0 = Disabled
Transition Counter Threshold

before a symbol is considered present and AGC can be resolved.
Usage: Can be useful in certain application where extraneous objects in the
field of view might require a higher threshold.
