    LED source to a photocell, and is referred to as the interrupter flag. When the machine is first switched on the reels spin at least two revolutions for the MPU6 to determine the exact reel position and check serviceability.

  • Page 52: Photo Components

    4.9.10 Reel bands Reel bands for the MPU6 may have 12, 16 or 24 symbols and may be of a wide or narrow type. The required number of “stops” is determined by the MPU6 program and makes no difference to the rest of the reel assembly.

  • Page 53: Reel Assembly Fixing

    The bands are designed to be easily removed and refitted without re-alignment being necessary. Each band is securely located beneath the rim on each side of the drum. Two pegs retain the band to secure and ensure correct alignment and prevent any slipping. The transparent leader at the start of each band is printed with machine identification and part number.

    The proprietary Barbus is a combined power bus and serial data link connected in a daisy chain layout between the machine modules as shown in Figure 2. The Barbus is connected to the MPU6 board via a red 11-way BARBUS connector as shown in Fig. 24, the connector having a keyway at pin position 7.

  • Page 56: Mux5 And Mux5E Boards

    Most gaming machines use more lamps, LEDs and illuminated push buttons than can be controlled directly by the MPU6 board. The MUX5 board block diagram is shown in Fig. 28 and provides the MPU6 system with the ability to control additional devices. The MUX5E is similar to the MUX5 in design, but provides an additional 64 lamps.

  • Page 58: Buttons Interface

    4.19 Buttons interface The MUX5(E) board can interface with 16 illuminated pushbuttons via a brown 13-way BUTTONS connector having a keyway at pin position 11. The interface's lamps and switches are each wired into a 2 x 8 matrix as shown in Fig. 29. The diode in the switch input line protects the transistor against +34V which might appear on the line under certain fault conditions.

  • Page 59: Barbus Interface

    4.20 Barbus interface The Barbus interface shown in Fig. 30. is based on the MPU6 board and is connected to the MUX5 board via a red 11-way BARBUS connector having a keyway at pin position 7. The Barbus provides a +34V supply for lamps and a +12V supply for electronics; these supplies are protected by on-board fuses.

    Fig 32. The connector has a keyway at pin position 9. When the MPU6 processor requires a reel to change position it transmits data to the REEL5 control board via the Barbus serial link. The REEL5 CPU produces a 4-bit pattern of pulses from the relevant parallel port, these pulses are amplified by current drivers and are output to the reel motor to drive the reel to the required position.
