Installation
The read head can make the following direction decisions based on the lane and possible
branches:
Follow left-hand lane
Straight ahead
Follow right-hand lane
The direction decision is signaled to the read head via the controller. If there is no direction
decision, the read head displays an error message.
Code Tapes for Control and Positioning
In addition to tracking the lane, the read head can also detect Data Matrix codes. This process
involves evaluating both control and position information. Data Matrix control codes are used
as event markers. Control codes provide information on branches. Data Matrix code tapes for
positioning indicate the absolute position of the read head.
Note the following conditions:
Data Matrix code tapes for positioning are used instead of the colored tape.
Data Matrix control codes are used in tandem with the colored tape or Data Matrix position
code.
