In order to customize various parameters for the PWM outputs, the configuration
panel must be “enabled” by plugging in the Factory Key or User Key (supplied); you will
then be in Proportional Drive Setup mode.  The display will initially be displaying
“Output” 1 +, no “Param” lights will be illuminated, and the “Value” lights will be
displaying the Start PWM and Max PWM as solid lights.  Also, a flashing “Value” light
will show the actual function output value.  The flashing light will move as the
corresponding joystick is moved, and you will also see the green light next to the 1+
output on J6 go brighter and dimmer.
To select the output pin you want to change parameters for, press the buttons
under the “Output” lights.  To change a parameter, press the buttons under the “Param”
lights until the desired parameter is lit up (Threshold, Start PWM, Max PWM, Ramp Up,
Ramp Down).  The “Value” lights will now indicate where the selected parameter is
currently set, in relation to the MAX and MIN values allowed for that particular
parameter (see table below).  Press the buttons below the “Value” lights to raise or lower
the parameter; if the value of the parameter is “in between” two lights, the two adjacent
lights will both be on at once, each with relative brightness corresponding to how far in
between the two lights the value is.  To change a parameter a long way, press and hold the
button and it will auto-repeat as on a computer keyboard.
The table below indicates the minimum, maximum, and increment values for each
of the proportional drive adjustments.  The default values for each parameter are specific
to each proportional output and are not listed.
