  1. Why Standards?

  2. Dataflow without Standards

  3. Dataflow with Standards

  4. Value Proposition • Visibility • Standards enable data communication on three levels – GDS, BOB, S2S and provide 360 degree visibility of patron behaviors, playing habit, game preferences, dining, hospitality, entertainment activities and more • Portability • More choices, simpler repeatable solutions, higher quality, Exit option • Investment Protection • Open standards are more robust • Ensures smooth migration path to achieve new functionality • Increased ROI • Increase revenues by 360 degree visibility on customer data • Decrease costs by using more effective and efficient tools to manage, analyze and evaluate productivity and profitability of operations

  5. Gaming Device Standard (GDS)

  6. GDS Structure • Currently, there are Five (5) workgroups • Coin Acceptor Workgroup • Note/Ticket Acceptor Workgroup • Hopper Workgroup • Touch Screen Workgroup • Printer Workgroup • Every Workgroup has a technical lead

  7. GDS Devices • The GDS committee has standardized the following devices • Coin Acceptor • Coin Hopper • Note/Ticket Acceptor • Touch Screen • The committee is working on the following standards • Printer Device • Template definition protocol • Magnetic/smart card Reader • Hybrid USB/Power connector • Device Firmware Upgrade (DFU) standard, developed by USB-IF, was selected to be the standard mechanism for GDS devices to perform firmware updates

  8. GDS Standards In Action

  9. General Information GDS devices utilize the Human Interface Device (HID) class, page 0x92 (Gaming Device Page), of the Universal Serial Bus (USB)

  10. General Information cont’d • GDS devices use full speed, 12Mbits/sec. • GDS devices are compliant with USB1.1 • Devices are event driven • Some events carry transaction ID (TID events) • An application level acknowledgment (ACK) is required for TID events • If an ACK is not received within one (1) second then the TID event is resent to the host • In case of failure, device will cease to report TID events • Some devices implement a Non Volatile Memory (NVM)

  11. USB + Power connector • Two proposals are under considerations • FCI • FoxConn • Power Requirements • Due to the nature of business, GDS devices require more power than can be supplied by the standard USB connector • GDS has identified two extra voltages • +24V @ 4A • +12V @ 2A • A GDS connector will have the two voltages available, by the host, at all times. • Only one voltage will be used by device class i.e. printers use +24V, Coin acceptors use +12V

  12. General Requirements • The following list is requirements of the USB and power connector: • USB interface • Dual voltage supply of additional +12V and +24V power • Mechanical retention • Polarised • Small Mechanical size • Robustness • EMC/Signal Integrity • Hot plugging (In gaming industry devices need to be hot plugging at both ends host/device) • Mechanical size: The maximum size of the PCB connector is 20 mm wide by 10 mm high. The maximum depth is 25mm.

  13. Power signals • The following signals are required: • D+ • D- • Vbus • USB Ground • +12V • +24V • Power Ground

  14. Current Rating The device must limit current to less than 1A until 90% of the final voltage is reached

  15. Mating Sequence

  16. Assumptions • By nature of industry, host will always be designed with a pre-known number of devices that will be connected to it. Thus power consumption is pre-calculated • The power supply shuts the system when overload condition happens for excessive power drawn from the devices • GDS devices would be declared as self powered devices thus eliminating the need for power management • Devices can either enumerate from USB power or +power

  17. Assumptions Cont. • GDS protocol allows for a device to enumerate from USB power. If external power (+12v/+24V) is not connected, device reports power status to host • With the above in mind, there is no need to modify any USB descriptors • The USB part of the connector must meet all the standard USB 2.0 electrical requirements • +power devices may be connected to a legacy host through conversion board that has “+power” connector on one side and standard USB and a power connector on the another

  18. GDS Goals for 2006 • Magnetic/Smart Card standard • Update GDS Toolkit to include all device standards

  19. Q & A
