Specifying the First Direction Decision
To ensure that the read head does not report any error messages after being switched on, a
direction decision must be specified. You can control the direction decision via the
INPUT_SELECTION_DIR_RIGHT and INPUT_SELECTION_DIR_LEFT inputs. See chapter
3.3.
Figure 4.1
Direction decision via protocol
If a decision on the direction to take is sent to the read head via a protocol, the input signals are
ignored until the read head is reset. See chapter 5.1.
4.2
Direction Decision
The read head has several ways of following colored tapes and Data Matrix code tapes
depending on the parameterization. Depending on the input signal, the read head follows the
right-hand, the left-hand, or the better lane.
