Why Standards?
Year of Implementation! Dataflow without Standards
Year of Implementation! Dataflow with Standards
Year of Implementation! 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
Gaming Device Standard (GDS)
Year of Implementation! 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
Year of Implementation! 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
Year of Implementation! GDS Standards In Action
Year of Implementation! General Information GDS devices utilize the Human Interface Device (HID) class, page 0x92 (Gaming Device Page), of the Universal Serial Bus (USB)
Year of Implementation! 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)
Year of Implementation! 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 4A 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
Year of Implementation! 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.
Year of Implementation! Power signals The following signals are required: D+ D- Vbus USB Ground +12V +24V Power Ground

Year of Implementation! 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
Year of Implementation! 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
Year of Implementation! GDS Goals for 2006 Magnetic/Smart Card standard Update GDS Toolkit to include all device standards
