Dedicated Switch Test
When you enter the Dedicated Switch Test , the LCD monitor will display the screen shown in figure
B5. The four dedicated switch strings are shown, grouped by their common ground wire. Each
square in each string corresponds to a specific switch; the color of the square represents the cur-
rent state of that switch.
Active switches, regardless of their type, are displayed in bright green squares. Inactive opto
switches are displayed in light tan (if normally unblocked) or dark tan (if normally blocked) squares;
all other inactive switches are displayed in bright blue (if normally open) or navy blue (if normally
closed) squares. Bad switches (switches that have been inactive for approximately 60 balls played)
are displayed in red squares. Unused positions in the matrix are represented by gray squares; any
unused position that is registering active (an error) is represented by a brown square.
Wire colors and I/O Board connector/pin numbers are shown for each string of switches.
You can simultaneously test as many switches as you like, or repeatedly test a single switch, observ-
ing the results on the screen. The game also provides an audible response each time the state of a
switch changes.
To exit the Dedicated Switch Test at any time, press the Back/Escape button.
