BASIC COMPONENTS
Monster Drop Chaos is a new spin to the Monster drop game. Players have to drop a ball onto the
wheel and try to time it correctly to win big time scores. The wheel, located in the middle of the
playfield, has 18 value holes including two designated “Chaos” features. When the Ball lands inside the
“Chaos” hole an event occurs in which 18 balls descend from the carrier, above the playfield, and
bombard the wheel with the opportunity to gather more points than the Mega Bonus. Monster Drop
Chaos also has a 42” display that hangs over the playfield, giving animated attractions to keep players of
all ages engaged and interested to see what will happen next.

III. Recommended Inputs
• Setting up Coin Comparator
o The Coin Comparator is a
section of the Coin Mech. that
compares one of your tokens
or quarters to the inserted
coin by the player. If the coins
do not match, the Coin Mech.
will return the inserted coin
to the player.
o The Coin Mech. is attached to
the coin tower in the front of
the cabinet.
o Detach the Coin Mech. by
unscrewing the lock nuts on
the back of the four carriage
bolts.
o Pull up on the tab of the Coin Mech. that states, “Slide to replace coin.”
10
o Place your token, under the lifted tab, in-between the two edges.
o Reattach the Coin Mech. to the button assembly by screwing the lock nuts onto the
four carriage bolts, and connect the wires so that the yellow wire is on top shown
below in blue, and the switch is in the up position as show in the red, as shown
below

ALTERNATIVE COIN/BILL AND CARD-SWIPE CONFIGURATIONS
There are a several alternative Card Swipe systems and Bill Acceptor configuration possibilities,
depending on your location. These are described in a general fashion as follows.
Note that the system expects the following timing ranges for any pulses:
Low time: 40-80ms
Up time: 100-150ms
CARD SWIPE SYSTEM
The Coin-Mech and/or Bill Acceptor can be replaced to set up a swipe-for-credits, or e-tickets scheme.
This is the recommended set up:
-Remove the Coin-Mech and/or Bill Acceptor and install your card swipe systems in the lower front door.
[Contact customer service if custom plastic plates for this purpose are required].
-Some of the necessary signal lines are available on the connector at the door:
> Enable signal, output.
> Bill acceptor line/Coin-in line, input
For the ‘Run’ and ‘Notch’ signals, you can tap directly from the lines on the Ticket Dispenser drawer, or
from the following pins at the control to coin door harness connection (9 pin UCL)
Ticket Notch: Blue wire on pin 6
Ticket Run: white wire on pin 8
- Have your card swipe system tap into the Bill/Coin signal line.
- Configure your card swipe system for a 1-pulse-per-swipe response or 4-pulse-per-swipe
- If tapping the coin signal line (Gray/yellow), when having 1 pulse-per-swipe, 1 swipe will count as 1 coin
internally.
- If tapping the bill signal line (Gray/yellow), when having 4 pulse-per-swipe, 1 swipe will count as 4 coins
internally.
- Configure the game to provide the necessary credits for the ‘coin’ count indicated above and the actual
money you will charge per-swipe.
- If possible (strongly recommended), hook up your system to the enable line (White/Yellow), so that the
game can stop money intake in case of any machine error or fault.
12
COIN MECHS
It is possible to use other coin mechanisms on this machine. The wiring harness terminates on both Spade
type connectors and an IDC connector for this purpose, the signal lines are:
# Wire Color Signal
Yellow 12V
Gray/yellow & Gray/Orange Coin Signal
White/yellow Enable (low=enable, high=disable) (this should
be hooked to coin-mech ground)
Black GND, actual DC Ground
Notes:
The ‘Device Ground/Enable’ line comes from the Mini High Current Board, as commanded by the main CPU
to enable or disable money intake. It is necessary that your coin-mech device has a coin-lock ‘reject’
solenoid so that this feature is available.
Normally, for an Imonex, if it has a coin reject solenoid, you hook the solenoid’s ‘ground’ to the enable line,
so that the game can control it.
For an electronic coin-mech, like the MPU, you hook up the coin-mech’s ‘ground’ to the enable line.
IV. Adjustments
• Ball Drop Adjustment
o The Ball Drop Assembly, located at
the top of the cabinet can shift and
may not be aligned correctly with the
wheel.
o If the Ball Drop Assembly is not
aligned correctly the balls dropped
onto the wheel will never be able to
fall directly into the holes on the
wheel, thus not making Monster Drop
Chaos a skill game.
o To re-align the Ball Drop Assembly,
obtain two straight edges (i.e. straight
piece of wood, or material that is sure
to be straight) longer than 30 inches
in length.
o Turn Monster Drop Chaos off.
o With straight edges in hand, run the
straight edges down both sides of the
Ball Drop Assembly and rest the
bottom ends on the wheel.
o Make sure there is a hole directly under the ball drop.
13
o If the straight edges rests on the wheel and are equal distant to the center of
the hole on the wheel, then the Ball drop Assembly is correctly aligned as
shown below on the left side.
o If the straight edges are not equal distant to the center of the hole on the
wheel, as shown below on the right, then the Ball Drop Assembly needs to be
adjusted.
o Grab a Philips head screw driver (P2), preferably with a neck longer than 9”.
o Slightly loosen the two
screws which lock the Ball
Drop Assembly in place in
the red circles, as shown
to the right.
o Shift the Ball Drop
Assembly in the direction
in which will align the
opening with the
corresponding hole on the
playfield.
o Use the two straight
edges to confirm that the
Ball Drop Assembly is in
the correct position
before tightening the two
screws to fasten in place.
14
V. Taking off Wheel
o To take the wheel off of the
playfield, several parts need to
be removed before this task can
be done.
o Firstly, unscrew and remove the
four acorn nuts that are
fastening the island to the
playfield, along with the island
itself as shown to the right.
o Secondly, remove all four
corners of the playfield by
unscrewing all 16 screws
anchoring the plates to the
playfield as shown below.
o The wheel is now able to be lifted out of the cabinet.

TECHNICAL OPERATION
21
Inter-Board Communication: 485 Serial pair
The Circuit Boards communicate with each other using a 485 differential
wire-pair network, using the SNAP software protocol layer.
- On this machine, this wire pair has colors Blue and Gray.
- The Main CPU Board acts as the master, initiating commands
and receiving responses from the slave boards.
- Like-boards differentiate from each other by means of an ID
Switch setting.
- See the previous pages to find each board’s ID-Switch location
and setting.
Note that we indicate the required on-off state of each micro
switch in the previous pages with 1’s and 0’s, respectively.
- The following PCB board(s) are NOT connected to the 485
network:
➢ The Power distribution board
-Note that the 485 network wire-pair chain jumps from board to board:
➢ In some places the chaining is done by double-crimps at the connector (these are usually 2-pin
connectors)
➢ In other places, PCB traces on the board itself carry the chain from a pair of connector pins to
the next (usually a four-pin connector); thus, disconnecting such a board’s 485 might actually
disconnect the rest of the 485 chain. Keep this in mind when troubleshooting or replacing
parts.

ERROR CODES AND TROUBLESHOOTING GUIDE TROUBLESHOOTING GUIDE
Following a methodical approach will make it easier for you to resolve issues with any type of equipment.
In most cases, machinery consists only of a set of input signals, a process for those signals, and some
resulting outputs. Separating the system into these three areas lets you have a clear map when looking for
solutions.
In general terms, to isolate a fault, you usually follow these steps (not necessarily in this order):
I. INPUT (from button switch, etc.)
• Determine if the related input signals (i.e. button, etc.) are reaching the processing stage, usually a
PCB board.
• Determine if its related input signal reaches the control system (i.e. board), by measuring
continuity in the wires.
• If there is still some doubt on the consistency of the connection, you can ground the input on the
board directly, by removing the connector in question and using a small wire to bypass the
harness and bring ground (or the appropriate signal) to it.
II. PROCESS (usually a PCB board)
• Check if power is reaching the device. If it’s a PCB board, it usually has a static LED light showing
it’s powered.
• Check if board is running, usually showing a separate flashing LED light.
• Check if the board has the right program, by checking the firmware name sticker on the board
surface.
• Swapping the board for a known-good replacement is a very common way to determine right
away if the problem lays with the board. Be mindful though, that there might be an external issue
that damages the board in the first place. That’s why it’s important to first check the power
voltage has the proper level, etc.
• If there are more than one like-boards on the machine, swapping them around will let you know if
the problem follows the board or if stays with the assembly section.
III. OUTPUTS (to light, solenoid, motor, or another PCB board)
• Determine if the process output signals are reaching the end-device
• Measure continuity on the wires from the output of the PCB board to the end device.
• If there is still some doubt regarding the connection, try activating the device directly by
disconnecting the output connector from the board, and using a spare piece of wire to feed it the
proper signal.
• For example, disconnecting the hi-current output board and feeding ground to one of the output
pins on the harness side, to activate a solenoid directly for a brief moment.
• Like in the other examples, swapping the device for a known good unit also helps in narrowing
things down.
