One Wire (A,B,C) LED
Control
When SW5-2 is On, it specifies One Wire (A,B,C) mode. In this case, a
single LED drive (Red or Green or Yellow) is wired with varying results
as shown in Figure 15.
One wire mode is typically used for older read heads with a single LED
that is either On, Off, or flashing.
