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.
To ensure that the reader does not report any error messages after being switched on, a
direction decision must be specified. You can control the decision direction via inputs
INPUT_SELECTION_DIR_RIGHT (IN2 / DIR_RIGHT) and INPUT_SELECTION_DIR_LEFT
(IN1 / DIR_LEFT) or via the protocol. See chapter 3.3.

Direction control via the protocol. See chapter „Modules with Input Data“ on page 43.
If direction decisions are made via the protocol, subindex 12 "Input Source Selection" must be
switched to Software.

input are ignored until the reader is reset. .
