The following table briefly identifies the various modules of the gaming machine.
Table 1-1 Video Gaming Machine Modules
Machine Module Description
Cabinet, Door and Top
Box.
The physical outer enclosure that provides for the location and mounting of
other modules.
Belly Panel Door This door is located on the main door, below the mid trim, and provides
access to the note stacker (where fitted) and main door fluorescent tube.
This door is fitted with a lock and a battery-backed security switch.
Video Monitor High-resolution nominally 640 x 480 pixels. It is actually set by the game for
improved-quality graphics. The monitor is the main medium for displaying
game operation and status to the player.
Main Board The Main printed circuit board (PCB) provides primary control of the gaming
machine. The Main Board is interfaced (via the Backplane) to all the major
components of the machine. The board receives signals from, and sends
control signals to machine components. The Main Board houses the central
processor and other logic components for game generation and video
drivers, security items, power control, memory storage, and communications.
Backplane
(may also be called
the Interface Board).
The Backplane houses an array of connectors that are used to electrically
connect (via direct mechanical coupling or through looms and ribbon cables)
the various electrical components of the machine to the Main Board.
I/O Driver Board The I/O Driver Board drives the lamps, receives inputs from the pushbuttons,
interfaces with the coin handling system, and extends communication
access.
Communication
Configuration Board
The Communication Configuration Board (CCB) 'piggy-backs' to the Main
Board. The board is used to set up the communications channels of the Main
Board (up to three) for external networks, bill acceptor and printer.
Logic Cage The logic cage consists of a secure, steel cabinet that houses the Main,
Communications Configuration, and I/O Driver PCBAs. The section of the
Interface Board that interfaces with the Main Board and the I/O Driver Board
is also located within the logic cage.
Power Supply
Assembly
The power supply assembly converts the AC mains input voltage into low
voltage DC power for the various machine modules and circuits. Power is
directed via the Interface Board to the machine components. The video
monitor receives AC power directly from the power supply assembly.
Coin Handling System The function of the coin handling system is to check the validity of coins
inserted, establish a count and pass signals to the Main Board. The coin
handling system directs coins to either the hopper, cash box, or coin tray.
The MAV500/MKVI is compatible with several different coin handling
systems.
Hopper (if used) The hopper acts as a holding unit for coins. When instructed by the main
board, the hopper returns coins to the player. For each coin ejected, the
hopper sends a signal to the Main Board. When the required number of coins
has been dispensed, the Main Board signals the hopper motor to stop.
Bill Acceptor (if used) The function of the bill acceptor is to accept valid note currency and register
the appropriate number of credits for gameplay. A note stacker is used to
store the notes.
