PoweredUSB Seminar Powered USB Technology for Retail Presented by Phillip Lembo Phillip Lembo • President of CyberData Corporation • Located in Monterey, California CyberData Corporation • Design, development and manufacturing company provide products to the retail industry for over 30 years. • CyberData is supplier to OEM’s as well as large end-users. • CyberData’s expertise is in peripheral interfacing including Ethernet, 802.xx wireless and USB. Evolution of Peripheral Interfaces • • • • Proprietary connections RS-232/Parallel USB PoweredUSB Old Proprietary Connections • Each manufacture had their own proprietary connector. • A single connector provided both power and communication signals. • Each connector was keyed (designed so that you could not plug a cash drawer into a display port). • Cable strain relief was locking and the cable was designed for a harsh retail environment. NCR 2127 (example) IBM 46XX (example) RS-232/Parallel - The first PC Connection • • PC’s began to enter the POS marketplace To provide “open system” connectivity, POS devices were designed for RS-232/parallel connections • POS manufacturers added additional serial ports to standard PC’s • Power to the peripheral: • External Brick • Non-standardized pin on connector Fujitsu TeamPOS 5000 Multiple-powered serial ports Standard USB Plug-and-Play • • • • • Support of USB on Win98SE onward Up to 127 device support Hot Pluggable Automatic device driver loading 500mA (half Amp) of +5 volt available Standard USB Connectors USB “A” Std. Host USB “B” Standard USB for Retail • No cable locking on the host or peripheral side connector (easy to pull out) • Limited amount of current to run POS devices (5volts @500mA) • Multiple voltages are not available ARTS has a plan • ARTS sees the vision of USB with added Power for Retail and proposes this as the next Retail standard. • IBM takes the idea and with FCI/Berg develops a PoweredUSB connector • IBM patents the PoweredUSB Host side connector keying methodology IBM SurePOS 700 • IBM implements a PoweredUSB POS terminal for their SurePOS 700 POS terminal • IBM informs ARTS that users of PoweredUSB need to pay a one-time fee to IBM. IBM SurePOS 700 What is PoweredUSB? • PoweredUSB is standard USB with extra power – USB +Power – Retail USB – USB Plus Power – PoweredUSB The Parts of PoweredUSB • • • • • Host-side connector Host-side cable connector PoweredUSB cable Peripheral-side cable connector Peripheral-side PCB connector The Parts of PoweredUSB Parts of PoweredUSB Host side PCB Mount connector Host side cable connector PoweredUSB raw cable Peripheral side cable connector Peripheral side PCB Mount connector Host-Side Connector • • • • Support of standard “A” connector +5, +12, and +24 volt keying options Each voltage has a different color connector 6 amps rating per connector Std. “A” Peripheral-Side Connector • • • • • +5, +12, and +24 volt keying options Each voltage has a different color connector 6 amps rating per connector Excellent locking feature, robust strain relief Hot pluggable Cable Requirements • • • • • Special cable required for PoweredUSB USB 1.1 or 2.0 compliant Combines power and USB signals Max recommend length: 4 meters (~13 feet) Make sure the cable meets the requirements Peripheral-Side Cable Connector • PoweredUSB spec. recommends connectors – – – Keyed and ground first contacts for hot-plugging Able to support USB 1.1 and 2.0 Able to support the current required • PoweredUSB spec. also says: “Peripheral side connectors are at the discretion of the manufacture as long as they meet good engineering practices and as long as this connector is not a Host type” Peripheral Side PCB Connector • PoweredUSB spec. recommends connectors – – – Keyed and ground first contacts for hot-plugging Able to support USB 1.1 and 2.0 Able to support the current required • PoweredUSB spec. also says: “Peripheral side connectors are at the discretion of the manufacture as long as they meet good engineering practices and as long as this connector is not a Host type” PoweredUSB Licensing IBM Patent • IBM patented the keying option of the host-side PCB connector • If the product uses a host-side PCB connector, users must obtain a license from IBM or purchase product from companies that have these agreements in place • IBM has been charging a one-time fee of $5k for this license • The cable and the host-side connectors are free from this patent requirement and do not require agreements with IBM Parts That Need IBM License Need IBM license Do not need IBM license Host side PCB Mount connector Host side cable connector PoweredUSB raw cable Peripheral side cable connector Peripheral side PCB Mount connector PoweredUSB and USB.ORG • ARTS, Berg/FCI, IBM and NCR tried (unsuccessfully) to get PoweredUSB approved under USB.ORG • Acceptance by ARTS, IBM and other large OEM’s have proven PoweredUSB viability even though it is not officially accepted by the USB.ORG. How to Implement PoweredUSB • Procure a POS system that supports PoweredUSB • Upgrade a standard PC with internal PoweredUSB Interface • Upgrade a standard PC with an external PoweredUSB interface Purchase a New POS system • All major POS manufacturers support PoweredUSB on their current retail terminals • NCR • Fujitsu • IBM • Wincor Upgrade with an Internal PCI Card • PCI card with 4 PoweredUSB ports • Multiple voltages available using the power supply of the PC • +24 volt printer support Upgrade with an External HUB • • • • External Hub with up to 6 ports Eliminate bricks - Power off standby mode +24 volt printer support Thin client support PoweredUSB Product Sources • PC4 carries these CyberData products: – PCI controllers – External hubs – Quality PoweredUSB cables • • • • • IBM NCR Fujitsu HP Digi-I/O networks PoweredUSB Peripherals • • • • • Symbol PCS HHP Hypercom Epson • • • • • TGP Citizen APG IBM Scantech ID Who is driving PoweredUSB? • • Every RPF from large retailers require it All major POS manufactures support it Value Proposition - Why Use It? • • • • • • It is the Retail connectivity standard All major RFP’s are asking for it Easy to implement Standardized interfaces Easy to service (hot pluggable) Minimal cost impact ARTS Approval • ARTS has approved PoweredUSB as part of the UnifiedPOS standard • This is important because it tells the retailer that this is the connectivity standard • http://www.nrf-arts.org/ Sources of Information www.PoweredUSB.ORG • PoweredUSB.ORG is an educational web site designed to help users understand PoweredUSB and its implementation. • PoweredUSB.ORG is working with major OEMs to update the PoweredUSB specification.
