1. Gaming Device Standard (GDS)

2. Global Gaming Expo - October 2004 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

3. Global Gaming Expo - October 2004 GDS Devices The GDS committee is working to standardize the following devices: Coin Acceptor Coin Hopper Note/Ticket Acceptor Touch Screen Printer Device

4. Global Gaming Expo - October 2004 GDS Standards In Action

5. Global Gaming Expo - October 2004 General Information GDS devices utilize the Human Interface Device (HID) class, page 0x91, of the Universal Serial Bus (USB)

6. Global Gaming Expo - October 2004 General Information contd 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)
