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.

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

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

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

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
