AUX DRIVER
When the Mux Enable parameter is programmed On, signals that
are routed through both J1 and J2 are active through both con-
nectors. If the Mux Enable parameter is programmed Off, these
signals are active only through J1.
Two J1 pins carry different signals depending on whether J2
is active. With J2 active (Mux Enable parameter On), J1 Pin 12
is the input for the Lift limit switch and Pin 24 is the input for the
coast switch. When J2 is not active, J1 Pins 12 and 24 are inputs
for the forward and reverse switches—as shown in Figure 3.
