Wiring the touchscreen
controller
If replacing a touchscreen controller board, the field
wiring terminal strips can plug into the new control board
without moving the wires over to the new terminal strips.
When moving the wires from the old green and orange
terminal strips to the new terminal strip, either move the
wires over one at a time or label all the wires as you
disconnect them from the old terminal strip so that they
are not mixed up during transition to the new
touchscreen controller.
