IMPORTANT SOLDERING TIP! Examine the Rotary Encoder:
regardless of whether the 3 silver terminals appear to you to be
tarnished, rub them anyway with a clean pencil eraser. This will
make for much easier soldering.
Figure 1.3. Encoder cable
connections
1-30. Strip 1/8" of
insulation from each of
the 3 wires of the
cable/plug assembly.
1-31. Study the
A-B markings on the
encoder and compare
to Figure 1.3.
1-32. The 3 wires
should be inserted from
the back and soldered
on the front side.
Insert the red wire and
the white A and gray B
wires EXACTLY how
Figure 1.3 depicts the
front of the encoder
and design of the plug.
1-33. Mount the rotary encoder to the display board with the
lock washer and nut provided. The washer goes on the front
side of the board. (If you wish, the large tuning knob may be
mounted temporarily to the encoder shaft for easy tuning during
progress tests).
1-34. Mount the SPDT power switch on the display board.
Both the tabbed "alignment" washer and the lock washer should
be on the FRONT side of the display board. Be sure to get this
switch mounting and wiring done correctly, because you will be
instructed in Phase 5.0 to cut off the un-used switch lug.
1-35. Strip 1/8" insulation from the ends of both red wires of
the pre-assembled power switch cable.
