One Wire ABC LED Control
When JP3 is not jumpered, 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 4.28.
One Wire ABC LED Control mode is typically used for older read heads that
have a single LED that is either On, Off, or flashing.
