SECTION 4 SYSTEM DESCRIPTION
The MPU6 system is a modular system comprising a number of key modules which in
combination provide a flexible, reliable and economic solution for today’s gaming machine.
The key modules are as follows:
•
MPU6 board.
•
MUX5 or MUX5E board.
•
Reel assembly including the REEL5 control board.
•
Switch Mode Power Supply.
The key modules are interconnected by a proprietary Barbus power/data link, which provides
D.C. power supply routing and integrates the modules into a working system. Each end of
the Barbus data link is terminated at the PSU interface board.
All machines based on the MPU6 system use essentially the same modules as listed above,
sometimes with an MUX5E or one and in some machines two MUX5 boards.
The obvious advantages of this approach have been well demonstrated with our previous
MPU6 systems.
Note that key modules used apart from the MPU6 unit are interchangeable with those of
previous Barcrest Group MPU5 systems.
4.1 General
A distributed processing system is used in which the MUX5(E) board and the REEL5 control
board are intelligent modules having on-board embedded processors operating under the
overall control of the main processor on the MPU6 board.
Communication between the MPU6 board and the intelligent peripherals takes place via the
Barbus, a proprietary power/serial data link interconnecting all the intelligent modules and the
switch mode Power Supply.
Fig. 1 shows how the various components are connected within a typical MPU6 machine.
The MPU6, MUX5(E) and REEL5 boards, together with the Transformer/Power Supply are
connected together via the Barbus.
Other items, i.e. lamps, buttons, LED's, displays, switches, coin mechanisms and data
capture (Datapak) are interfaced through individual harnesses to the MPU6 board directly or
via MUX5(E) board(s).
The MPU6 harness also includes an expansion connector for adding peripherals that may be
used in the future.
