3.10 Setting the DIP Switches
Each branch of the ClassWork Plus Line Multiplier contains two DIP switches. You
must set these DIP switches to the Student Number of the first and last student in
each branch. Take a look at Figure 3-12. Tables 3-1 and 3-2 show you how to set the
DIP switches for this application.
Figure 3-12. Typical ClassWork Plus classroom with 30 students connected
