Why Standards?
Dataflow without Standards

Dataflow with Standards
2005 - 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)
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

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 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
2005 - 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

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