INTRODUCTION
GAME FEATURES

GAME PLAY

MINI DUNXX™ is the newest member to our coin-op
family of exciting basketball games and is designed
with young children in mind. As with our FULL
COURT FRENZY™ games, the basket moves,
adding excitement that only this basketball game
can provide.

The game begins when the player inserts money
into the game. When sufficient money is inserted
into the game to create 1 “credit”, the “Start” button
will flash on the game. (The game can store up to
99 credits, and can be set to play for 1-4 coins per
credit.)

MINI DUNXX™ utilizes state-of-the-art sound effects
to add to the excitement of game play. Blending
children’s voices with a catchy theme song makes a
combination that children really love.

Once the player presses the flashing “Start” button,
the game begins. The ball gate opens to release the
basketballs, and the whistle sounds to begin the
game.

The basket movement is controlled by a proven
gear-motor design, along with reliable sensing and
motor drive electronics.

Once the game begins, the hourglass display starts
the “sand” running, and the basket begins its first
movement.

Game set up is a snap. JUST PLUG IN AND PLAY.

As the game progresses, the basket will move every
few seconds, and stop in a new position.

Game design and graphics have been made
specifically with young children in mind. The game
height and ball return system have been made for
the smaller height of youngsters. The basketballs
that are used were selected because they’re easy
for children to pick up, and light enough for them to
throw. They are also soft, so they won’t cause
injuries.

As the players make baskets, the game will make a
“swish” sound, or one of the four phrases: “Alright!”,
“Yeah!”, “Awesome!”, or “Great Shot!” will be heard.
“New High Score!” will be heard if they break the
previous record.
Just before the game ends, the ball gate will close,
to capture the balls.

The game has a fully adjustable ticket dispensing
feature with a ticket “cap” to allow the younger
children to get an ample amount of tickets, yet
prevent the older children from getting too many.

As the game ends, a horn sounds to signify the end
of the game, and the words “Game Over” can be
heard.

All game play features are adjustable, including:
game time, coins per play, and attract mode on/off
and length. It even comes with the option to allow
you to stop the basket from moving, if desired.

At this time, if your game is equipped with a ticket
dispenser, tickets will be awarded. The game is
then ready to be played again.

The control panel on the game has a unique timing
device. An electronic “hourglass” is utilized, being
easily identified and used by young children. An
oversized score display was also put in, for greater
appeal. The control panel is rounded out with the
use of bright colored shapes to add an eye-catching
look to the game.
MINI DUNXX™ uses a rotating beacon light to add
thrill to the game as points are earned. The operator
can adjust how often the light comes on. The light is
automatically activated during the attract mode.
Metal mesh is used on the sides and top of the
game for an attractive, long, maintenance free life.

4. Before closing up the game, adjust the game
volume by using the adjustment knob located on
the Main P.C. Board.

OPTION MODES
MODE 1
COINS PER CREDIT
(COIN 1)
This mode determines how many coins are needed
for 1 credit on the LEFT HAND COIN CHUTE. The
number displayed is how many coins it needs.
EXAMPLE: A setting of 2 would mean it would take
2 coins to get 1 credit or 1 game. The game default
value is “1” for 1 coin per credit.

PROGRAMMING BUTTONS
This section will give you a detailed explanation on
the functions of, and operating characteristics of
each of the programming buttons. Please read this
section carefully to avoid problems with your game.

MODE 2
COINS PER CREDIT

7

SET-UP / TESTING
Setting a “0” turns this option off. The factory default
setting for this option is “0” for off.

MODE 3
ATTRACT MODE INTERVAL

MODE 8
ROTATING LIGHT INTERVAL

This mode controls how often the “Attract” mode
comes on in this game. The Attract mode only
comes on when the game is not in use. When this
mode comes on, the game sounds are played and
the basket moves back and forth. This mode lasts
about 20 seconds. The time between Attract modes
can be set in 5 minute increments from 5 to 30
minutes. Setting a “0” turns the option off. The
factory default setting is “5”, for 5 minutes.

This mode controls how often the rotating lights
come on. Every time a player scores 3 points, the
game says something to the player. This option is
tied into when the game says something. The game
can be set for the lights to go on each time the game
says something, up to every 4th time the game says
something. Setting a “0” turns this option off. The
factory default setting is “2”, every 2nd time the
game says something.

MODE 4
TIME PER CREDIT

MODE 9
MAXIMUM TICKETS

This mode controls how long each game lasts. This
game can be adjusted from 20 to 45 seconds per
game, in 5 second increments. The factory default
setting for this option is “40” for 40 seconds.

This option is used to limit the amount of tickets that
can be given at the end of the game. This option is
used to prevent older, more skilled children or
adults, from getting too many tickets from the game.
This limit can be set from 1-99 tickets. Setting a “0”
turns this option off. The factory default setting for
this option is “25” for a 25 ticket limit.

MODE 5
JUST FOR PLAYING TICKETS
This option can be used in 2 ways. When any other
ticket options are enabled, this mode can be used to
give a player tickets, if they were unable to score
enough points to get tickets any other way.

MODE 10
BASKET ON / OFF

If this option is used with all other ticket options
disabled, it can be used to payout XXX amount of
tickets, regardless of game score.

This option is used to turn the movement of the
basket on or off. It may be desirable under certain
circumstances, to keep the basket from moving for
extremely young children. This option will allow you
to do this. We do however, recommend that you
keep the basket moving for greater player appeal.
Setting a “0” turns the basket off. The factory default
setting for this option is “1” for on.

This option works by setting a number that relates to
how many tickets will be dispensed when one of the
above scenarios are used. Setting a “0” turns this
option off. The factory default setting for this option
is “3”, for 3 tickets.

MODE 6
POINTS PER TICKET

MODE 11
ALARM MODE ON / OFF

This mode determines how many points must be
scored for EACH ticket dispensed. This can be
adjusted from 1 to 20 points, in increments of 2
points. Setting a “0” turns this option off. The
factory default setting is 6, for 6 points per ticket.

This option allows the AUDIBLE TAMPER ALARM
to be turned on or off. Select a “0” to turn the alarm
mode off. Select a “1” to turn the alarm mode on.
The factory default setting is “1”.

TESTING

MODE 7
TICKET THRESHOLD

After set-up is complete, play a few games to verify
everything is working correctly. Pay special
attention to the Ball Gate, Basket Movement,
Scoring, and Score Displays.

This option makes it possible to dispense tickets
ONLY after the player has scored XXX amount of
points. This setting is adjustable from 0-20 points.

MAINTENANCE
GENERAL MAINTENANCE

GAME CABINET AND GRAPHICS

The MINI DUNXX™ Basketball game has been
engineered to be as maintenance free as possible.
There are, however, a few things you can do to keep
your game in top operating condition at all times.
Following the guidelines below will ensure a long,
trouble-free life for your game.

The game should be cleaned occasionally to keep it
bright and attractive looking. Clean the cabinet
sides with a good cleaner such as “Fantastik”® or
“409”® and a soft rag. Follow cleaning with a
furniture polish, such as Pledge®.
NOTE: DO NOT USE ALCOHOL, THINNERS OF
ANY KIND, OR PINBALL PLAY FIELD CLEANERS
ON ANY OF THE CABINET SURFACES
ESPECIALLY THE DECALS.

BASKETBALLS
The basketballs in this game should always be kept
inflated to the proper size. If the balls are too big or
small, they will not work properly in the game. Use
the inflation gauge supplied to keep the balls inflated
to the proper diameter.

IF YOU HAVE ANY QUESTIONS OR COMMENTS
REGARDING INSTALLATION OR PROPER
FUNCTION OF YOUR GAME, PLEASE CALL OUR
SERVICE DEPARTMENT AT:

The amount of balls is also VERY IMPORTANT to
play value in the game. Always keep at least 8 balls
in the game at all times. This ensures there are
always enough available during the game. It would
be a good idea to keep extra balls available to
replace worn or damaged balls. The balls can be
obtained easily through our Service Department at
(716) 759-0360.

I.C.E. SERVICE DEPARTMENT
716-759-0360
NORMAL BUSINESS HOURS ARE:
MONDAY – FRIDAY, 9:00 AM TO 6:00 PM EST

TICKET DISPENSER
The Ticket Dispenser on the game is relatively
trouble-free, however cleaning the unit occasionally
from bits of ticket dust will keep the unit working
reliably. Use high-pressure air, (such as from an
aerosol can,) to blow dust build-up from the
mechanism and optical sensor. Clean the drive
wheels with an isopropyl alcohol,

COIN MECHANISM
The coin mechanism occasionally needs to be
cleaned to remove build-up of dirt and debris.
To clean mechanism, remove the coin mechanism
from the game and clean it with soapy water. Dry it
thoroughly and re-install. Test for proper operation.

MECHANICAL REPAIR
OPERATIONAL BACKGROUND
The following will outline the basic operating principles
of the MINI DUNXX™ Basketball game.
The movement of the MINI DUNXX™ Basketball
game hoop is operated through a gear motor control
that moves the basket assembly back and forth. This
is a 12 volt gear motor that has power to it applied
and reversed by the game electronics.

The following sections will give you detailed
information on repair, replacement, and adjustment
of the game’s components.

MECHANICAL REPAIR
WARNING: ALWAYS REMOVE POWER TO THE
GAME, BEFORE ATTEMPTING ANY SERVICE,
UNLESS NEEDED FOR SPECIFIC TESTING.
FAILURE TO OBSERVE THIS PRECAUTION
COULD RESULT IN SERIOUS INJURY TO
YOURSELF OR OTHERS.

It is useful to know that power to the gear motor is
chopped through the game software to allow software
control of the motor speed. The motors are run at a
50% duty cycle. This is important to know if the
circuitry is being analyzed by oscilloscope. Direction
of the gear motor is achieved by reversing power.
The electronics have built-in dynamic braking to stop
the motor quickly.

BALL GATE
BALL GATE REMOVAL
Ball gate removal is accomplished in the following
order:

The positioning of the basket assembly is
accomplished through an optical encoding system.
The system uses a decal with alternating reflective
and non-reflective surfaces as a medium for the optic
L.E.D.’s. A system of 3 L.E.D.’s are used to
determine position of the backboard. The high / low
pulses sent out by the encoder P.C. Board are
received and interpreted by the Main P.C. Board.
These signals are then converted to commands by
the software, depending upon game conditions. This
type of operating system allows limitless control by
software design, allowing easy repairs of the game in
the field, thus avoiding expensive and sometimes
difficult mechanical field modifications.

1. Turn off all power to the game and remove the
A.C. Power Cord.
2. Climb into the game and unplug the 2 pin
connectors that are attached to the Ball Gate
Driver P.C. Board.
3. Cut the tie wrap that secures the harness to the
Ball Gate Motor.
4. Loosen the (2) Allen Head screws that are on
the Ball Gate on the opposite side of the motor.
5. Push the shaft at the end of the ball gate into the
gate, and the entire assembly can now be
removed.

The game also uses reliable optical detectors for ball
sensing. This creates a sensing system that has a
much longer life span than its mechanical
counterparts. The Receiver P.C. Board receives a
pulsed light beam from the Emitter P.C. Board at a
specified frequency. This helps eliminate background
electronic noise that could cause interference. The
receiver L.E.D.’s incorporate automatic gain control to
consistently adjust to changing environmental
circumstances.

PLEASE NOTE: THE THREAD LOCKING
COMPOUND USED TO SECURE THE SHAFT TO
THE BALL GATE MAY PREVENT THE SHAFT
FROM SLIDING INTO THE BALL GATE EASILY.
USE A PAIR OF PLIERS (IF NECESSARY) TO
TURN THE SHAFT IN TO THE BALL GATE.
THE BLACK VELCRO POSITIONED ON THE END
OF THE BALL GATE IS USED TO PREVENT THE
OPTICAL ENCODER CLOSEST TO THE MOTOR
SHAFT FROM REFLECTING ON TO THE END OF
THE BALL GATE, WHEN IN THE CLOSED
POSITION. THIS MUST BE LOCATED RIGHT UP
AGAINST THE MOTOR SHAFT FOR THE BALL
GATE MECHANISM TO WORK PROPERLY.
PLEASE DO NOT REMOVE THIS VELCRO STRIP
FROM THE SHAFT, EXCEPT TO REPLACE IT.

The ball gate system on the game is operated by a
rotational gearbox. The Driver P.C. Board flip-flops
incoming D.C. power to operate the unit. Operating
the D.C. power with one polarity opens the ball gate.
Reversing polarity causes the ball gate to close. The
reversing of current is accomplished through a
combination of hardware and software from the
game’s Main P.C. Board.

MECHANICAL REPAIR
BALL GATE DRIVER
P.C. BOARD REMOVAL

MOTOR HOUSING REMOVAL
It is necessary to remove the Backboard to service
the Gear Motor or Clutch Assembly.

1. Loosen the (2) Allen Head screws that hold the
Ball Gate to the Ball Gate Motor.
2. Remove the (2) screws and star washers that
hold the P.C. Board to the motor.
3. Unsolder the wires from the motor. NOTE:
REMEMBER WHICH WAY THE WIRES ARE
ATTACHED TO THE MOTOR.
4. Check the motor for proper operation. This can
be done by hooking it up to any 5-12 volt D.C.
power source and checking for smooth rotation
without any binding or skipping.
5. Check the Ball Gate Driver P.C. Board for proper
operation. (For details on testing, refer to the
electronics section of this manual.)

1. Remove the (4) Phillips head bolts that hold the
Motor Housing to the Backboard.
DO NOT PULL THE ASSEMBLY AWAY FROM THE
REAR OF THE GAME UNTIL THE HARNESSING
HAS BEEN DISCONNECTED.

MOTOR OR CLUTCH REMOVAL
1. Unplug the (3) single pin connectors for the
score sensor. (Make sure when you re-connect
them, that you match the wire colors).
2. Remove the (3) Allen Head screws that hold the
Backboard Mounting Bracket to the Clutch.
3. Remove the (1) Allen Head Shoulder Bolt that
holds the Backboard Bearing to the Motor
Housing.
4. Slide the Backboard Mounting Bracket off of the
Motor Housing and Clutch.
5. If removing the Clutch, remove the (2) Allen
Head Set Screws that hold the Clutch to the
motor shaft, as well as the “E” clip. Pull the
Clutch off of the motor shaft using a twisting
motion.

IMPORTANT: WHEN RE-ASSEMBLING THE BALL
GATE ASSEMBLY, IT IS NECESSARY TO KEEP A
SPACING OF 3/16” TO 1/4” BETWEEN THE BALL
GATE AND THE EDGE OF THE OPTICAL
ENCODERS. IF THESE ARE SPACED
IMPROPERLY, THE SENSORS WILL NOT WORK
PROPERLY AND THE BALL GATE WILL EITHER
CONTINUE TO ROTATE OR STOP IN STRANGE
POSITIONS.
BE SURE THE OPTICAL ENCODERS FACE
STRAIGHT UP ON THE P.C. BOARD, AND ARE
NOT BENT OVER TOWARDS THE MOTOR
SHAFT. IF THE ENCODERS ARE BENT
TOWARDS THE SHAFT, THE BALL GATE WILL
CONTINUE TO RUN.

BACKBOARD SERVICE
ENCODER P.C. BOARD
The Encoder P.C. Board may be serviced by
removing the backboard from the game.
1. Remove the backboard from the game by
removing the (4) Phillips head bolts that hold the
backboard to the Motor Housing.
2. Remove the (2) hex spacer nuts that hold the
Encoder P.C. Board to the Motor Housing.
3. Remove the connector from the Encoder P.C.
Board. Please be sure the connector is installed
the same way when re-assembling the game.

ELECTRONIC REPAIR
COULD RESULT IN SERIOUS INJURY OR
DEATH. Using a small flat blade screwdriver, pry
the fuse from the fuse holder, or turn the cap off of
the fuse holder, and remove the fuse.

The following section will describe repair procedures
and trouble shooting hints for the game electronics.
Please read the section “Operational Background”
located in the “Mechanical Repair” section of this
manual. This will give you a good idea of the
game’s overall operating parameters.

NOTE: ALWAYS TEST THE FUSE WITH A VOLT
METER, EVEN IF THE FUSE LOOKS GOOD.
THERE SHOULD BE NO RESISTANCE NOTED
WHEN TESTING FOR CONTINUITY. THIS TEST
MUST BE PERFORMED, AS CERTAIN TYPES OF
FUSES HAVE THE POTENTIAL TO ONLY BLOW
PARTIALLY, GIVING THE APPEARANCE OF
WORKING FINE, UNTIL A LOAD IS PLACED ON
THEM.

WARNING: EXERCISE CAUTION WHENEVER
WORKING WITH ELECTRONICS, AS THEY CAN
BE VERY SUSCEPTIBLE TO DAMAGE FROM
SHORT CIRCUITING OR PHYSICAL ABUSE.
ALWAYS UNPLUG THE GAME WHEN WORKING
ON HIGH VOLTAGE AREAS OF THE GAME,
SUCH AS THE TRANSFORMER OR MONITOR.

Replace the Main P.C. Board fuses with the original
type and value. USE SLO-BLO MDQ TYPE fuses
only. Other types of slo-blo fuses may cause
strange problems with the game.

USE EXTREME CAUTION WHEN USING VOLT
METERS TO DO CIRCUIT CHECKS IF THE GAME
POWER HAS BEEN LEFT ON.
WHEN USING A VOLT METER, BE SURE IT IS
SET TO THE CORRECT VOLTAGE OR
RESISTANCE RANGE, BEFORE USING. THIS
CAN PREVENT POSSIBLE DAMAGE TO THE P.C.
BOARD OR MISDIAGNOSIS.

CHANGING A.C. VOLTAGES
Voltages are easily changed on the Main P.C.
Board. A convenient voltage selection switch is
mounted towards the center of the board. Be sure
of the voltage you require, and simply slide the
switch to the correct voltage setting.

ALWAYS REMOVE POWER TO THE GAME WHEN
PLUGGING OR UNPLUGGING P.C. BOARDS.

MAIN P.C. BOARD

IT IS NECESSARY TO USE I.C.E. REPLACEMENT
PARTS TO CONTINUE WARRANTY COVERAGE.
USE OF NON-I.C.E. APPROVED PARTS WILL
NOT ONLY VOID YOUR WARRANTY, BUT COULD
CAUSE SERIOUS HARM TO THE GAME OR
CAUSE SERIOUS BODILY INJURY.

IMPORTANT: BEFORE REMOVING THE MAIN
P.C. BOARD FOR SERVICE OR REPLACEMENT,
RECORD ALL INFORMATION REGARDING
CUSTOM OPTION SETTINGS, SO THESE
SETTINGS CAN BE RE-INSTALLED LATER IF
NECESSARY.

IF YOU HAVE ANY QUESTIONS REGARDING
REPAIR AFTER READING THIS SECTION, CALL
OUR SERVICE DEPARTMENT AT (716) 759-0360
BEFORE PROCEEDING.

The Main P.C. Board is located inside the Main
Cabinet beneath the ball tray.
When performing service on the Main P.C. Board, it
is a good idea to remove the board when replacing
even socketed or snap-in components. This can
avoid any possible costly errors that may occur
otherwise.

FUSES
Fuses are the first thing that should be checked
when the game either appears not to work, or
appears to work incorrectly.

Remove the Main P.C. Board in the following
manner:

There are 3 fuses in this game. The fuses are
located on the Main P.C. Board. 2 of the fuses are
for low voltage D.C., and are exposed on the P.C.
Board. One of the fuses is for high voltage A.C.,
and is in an insulated housing.

1. Remove all A.C. Power to the game. (REMOVE
THE POWER CORD FROM THE A.C.
RECEPTACLE.)
2. Disconnect all Mate-Lock connectors from the
game.

To check or service the fuses, FIRST REMOVE THE
POWER CORD FROM THE WALL OUTLET.

ELECTRONIC REPAIR
To change the Receiver:

3. Remove the (6) plastic nuts the retain the P.C.
Board to the mounting bracket.
4. Carefully remove the Main P.C. Board
5. Re-assemble in reverse order.

a) Remove the receiver cover.
b) Remove the (3) single pin connectors
from the motor harness to the Receiver.

BALL SENSORS

c) Unplug the Emitter harness from the
Receiver.

It is not necessary to remove the hoop from the
backboard to service the ball sensors. This
operation can be easily accomplished while still on
the game.

d) Remove the plastic nuts that retain the
Receiver to the housing.
e) Re-assemble in reverse order.

1. Remove power to the game to prevent damage
to the electronics when connecting or
disconnecting game harnessing.
2. Try to determine which sensor is at fault, Emitter
or Receiver. This can be determined as follows:

REMEMBER TO CONNECT THE HARNESSING
TO THE STRAIN RELIEF TO KEEP THE
HARNESSING FROM FALLING DOWN INTO AN
AREA WHERE THE BALLS COULD HIT IT.

SCORE DISPLAY P.C. BOARD

a) If pilot L.E.D. on receiver is lit brightly,
and intensity doesn’t change regardless
of blocking the Emitter, the Receiver is
probably bad.

The score display can be serviced as follows:
a) Remove all A.C. power from the game.
b) Remove the (3) Allen Head screws that
hold the retaining bracket for the score
display, and remove the bracket.

b) If pilot L.E.D. flashes when the receiver is
blocked, but score is not seen during
game play and harnessing proves good,
the Receiver is probably bad.

c) Lift the control panel containing the score
display from the game.

c) If pilot L.E.D. is lit dimly, or strobes dimly,
the Emitter is probably bad.

d) Disconnect the harnessing from the score
display.

To change the Emitter:
a) Remove the Emitter and Receiver
covers.

e) Remove the (8) plastic nuts that retain
the display to the control panel.

b) Unplug the Emitter harness from the
Receiver (closest to the backboard.)

f)

c) Remove the Emitter harness from the
hoop. REMEMBER HOW TO ROUTE
THIS HARNESS WHEN INSTALLING
THE NEW EMITTER.
d) Remove the plastic retaining nuts.
e) Re-assemble in reverse order.
