Introduction to the WS4/WS4 LX FRUs

Introduction

The Workstation 4 has been a very successful MICROS POS terminal - in fact, the greatest selling unit in company history. It is now over four years old with over 172,000 units in the field. PMA 07-892 announces the WS4 end-of-life in July 2007, with hardware support available through 2012.

This edition of th e Fiel d S ervic e Guide intr oduc es th e Workstation 4 LX system board and related FRUs. All other components including casework, LCD, power supply, touchscreen, and mag stripe reader are common to both workstations.

• Base Casework and Sheet Metal Components - WS4 and WS4 LX

This section contains base plastics, rear door and hinge, sheet metal components,

rubber feet, hardware and miscellaneous plastic. There are two bases available,

with usage is determined by the System Board Revision.

• System Boards, Components and Power Supply

This section begins wit h a brief hi story of t he Workstati on 4 system boar d through

the WS4 LX. To keep confusion to a minimum, each system board is referred to

by a model number designation.

• Workstation 4 System Board and Components

This section includes the original Workstation 4 System Board and major components including a bare sys tem board, Power Supply, CF Daughter Card, Boot Loader, Disk On Chip, DIMM, and CF card.

• Top Cover - LCD, Touchscreen, and Mag Stripe Reader

This section includes top cover components such as the LCD panel, touchscreen, and mag stripe reader. The Sharp LCD Panel recently changed from the LQ121S1LG41 to the LQ121S1LG61, requiring an update to the INF file that controls backlight bri ght ne ss levels. Units with the LG61 LCD ship wit h GR 2.3a platform software.

• LCD Customer Display - WS4, WS4 LX, and WS5

Includes all replacement components for the Rear or Pole LCD based customer display. This display may be found on the WS4, WS4 LX and the WS5.

System Boards and Components

This section starts with a discussion of each system board revision from the first generation, through the first ‘ROHS’ compliant revision, then on to latest system board, the WS4 LX.

In order to keep confusion to a mini mum, each sys tem board is refe renced by a model designation printed on the board.

WS4 System Boards - A Short History

The AB28-’n’ designation (where ‘n’ represents the hardware revision), indicates the ‘original’ non-ROHS compliant series of WS4 System Boards. Close to 100000 units were produced with the AB28 Series, including AB28-F, AB28-G and AB28-I.

Figure 1-2 displays the AB28-I System Board, the most numerous example of the AB28 series, and points out the location of the model number.

Introduction to the WS4/WS4 LX FRUs

System Boards and Components

Figure 1-2: The AB28 Series Workstation 4 System Board

The transition from AB28-F/G to AB28-I system boards combined with the change from a Samsung LCD to a Sharp LCD forced changes in the LCD and backlight cables. This is reflected in the section on replacement cables.

Another important change between the AB28-F/G, and AB28-I system boards is the addition of a multiplexer on the COM 3 port, shared between the Mag Stripe Reader and Customer Display port. The AB28-I System Board required updated platform files in order for the mag stripe reade r and customer display interfaces to f unction properly. Chapter 2 provides more detail about the multiplexer.

Introduction to the WS4/WS4 LX FRUs

System Boards and Components

The first RoHS (Reduction of Hazardous Substances) compliant Workstation 4 System Board is designated ABRD36-B replacing the AB28 series. The Revision A did not enter produ ction . The WS4 DiagUt ilit y views this bo ard as an ex tensi on of th e AB28 series, displaying Revision ‘K’ in the ‘Hardware Revision’ field.

The primary difference between the ABRD36-B and AB28 series is the AMD Geode SC3200 Processor packaging . Sever al ot her compone nts wer e also up dated to ‘ge t the lead out,’ in addition to five other hazardous substances included in the RoHS directive.

The ABRD36-B board is equivalent to the AB28-I board, using the same interface cables, CF Card, DIMM, Boot Loader and Disk On Chip. Platform software GR2.2 (or GR2.3a if the LG61 LCD is used) is re qui red. Figure 1-3 displays a sample of this board and the model number location.

Figure 1-3: The ABRD36-B or Rev K Workstation 4 System Board

The board pictured above doe s not i nclude a proce ssor he at si nk, b ut the first unit s did include one. The AMD Geode SC3200 packaging used on the AB28 board series did require a passive heat sink to maintain internal temp eratures and this carried o ver to the initial production of the ABRD36 system board. However, subsequent testing in the heat chamber indicated that the ROHS packaging offered improved heat dissipation and heat sink was not required.

Production of the ABRD36 board ends with the int r oduc ti on of th e Workstation 4 LX System Board.

System Boards and Components

The Workstat ion 4 LX System Board

The Workstation 4 LX System Board is also ROHS compliant and uses the designation ABRD86-n, where ‘n’ represents the hardware revision. More than just a board ‘spin’, the LX is a new hardware architecture - requiring a new API, and platform files. The CAL Client and MICROS applications consider it a new terminal. Chapter 4 includes a technical overview of this board.

The LX System Board is based on the x86 compatible AMD Geode LX800 processor and CS5536 Companion Device. This processor, when combined with USB Flash Drive technology to replace the relativity slow (and soon to be EOL) Disk On Chip results in a unit that benchmarks up to three times faster than the original WS4 with a MICROS POS application. Figure 1-4 displays a sample of the ABRD86-D System Board and model number location.

Figure 1-4: The Workstation 4 LX System Board - ABRD86

Highlighted Changes:

• Blue Operator LED distinguishes the WS4 LX from the original WS4.

• Disk On Chip replaced with USB based flash drive.

• The PCMCIA Socket is replaced by the Mini-PCI socket, to accommodate a Mini-PCI wireless card. The WS4 LX IO Plate includes a cut-out for an SMA style antenna connector included in the kit.

• The PS/2 Mouse and Keyboard connectors are replaced by two additional USB Ports. This means that an IO plate fro m the original WS4 will not fit the LX System Board.

• The Ethernet Controller supports 1Gbit LANs.

• General Software’s Embedded BIOS 2000 BIOS replaces the original WS4 Boot Loader. It provides the environment for creating custom pre-boot firmware utilities such Windows CE Factory Restore.
