Why Standards?

2005 - Year of Implementation!

Dataflow without Standards


Dataflow with Standards


Value PropositionVisibility

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)


GDS Structure

Currently, there are Five (5) workgroupsCoin Acceptor WorkgroupNote/Ticket Acceptor WorkgroupHopper WorkgroupTouch Screen WorkgroupPrinter Workgroup

Every Workgroup has a technical lead


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


GDS Standards In Action


General Information

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

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)


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


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.

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


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


GDS Goals for 2006

Magnetic/Smart Card standard

Update GDS Toolkit to include all device standards
