Note
Priority
Data Matrix code tapes and Data Matrix tags have priority over colored tapes or colored lanes.
If the read head detects a Data Matrix code tape or Data Matrix tags in the field of view, colored
tapes or colored lanes in the field of view are ignored.
Note
Branches/Intersections with Data Matrix Position Code
Observe the following guidelines less than 1 m before and after branching or intersection of a
lane with a position code:
• The position codes of the main lane must run continuously for 2 m. The position codes of
the branching/intersecting lane must run continuously for 1 m. The read head outputs the
X-value of the Data Matrix code tape that is specified the direction decision. See chapter
4.1.
• Do not use repair tape.
• Do not use colored tape.
• The difference between the absolute position of the main lane and the starting position of
the branching/intersecting lane must be greater than 1 m.

Figure 3.12
Behavior of the Read Head at Branches and Corners
The read head behaves differently depending on the type of branch and the specified lane. The
read head must know the upcoming direction decision.
A second lane branches off to the left from the straight lane:
The read head follows the straight lane if the direction decision "follow right-hand lane" has
been made.
A second lane branches off to the right from the straight lane:
The read head follows the straight lane if the direction decision "follow left-hand lane" has been
made.
A single lane with a position code turns to the left or right:
The read head follows the position code if the direction decision "straight ahead" has been
made.
