6.10.2 Alignment of cascades
First of all, the light grid directly connected to the control unit is adjusted as described under
6.10.1. In this regard, the output cables to the next light grid must be separated and
terminated with the termination plug WAC1.
The second light grid can now be connected and adjusted. It is possible to connect two light
grids in cascade in this way.
