Workstation 4 and 4 LX Field Service Guide 1-5

Introduction to the WS4/WS4 LX FRUs

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 minimum, each system board is referenced 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.

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 reader and customer display interfaces to function

properly. Chapter 2 provides more detail about the multiplexer.

1-6 Workstation 4 and 4 LX Field Service Guide

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 production. The WS4 DiagUtility views this board as an extension of the

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. Several other components were also updated to ‘get 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 required. 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 does not include a processor heat sink, but the first units did

include one. The AMD Geode SC3200 packaging used on the AB28 board series did

require a passive heat sink to maintain internal temperatures and this carried over 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 introduction of the Workstation 4 LX

System Board.

Introduction to the WS4/WS4 LX FRUs

System Boards and Components

The Workstation 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 from 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.

and components.

Figure 1-5: Original Workstation 4 System Board and Components

• Bare Workstation 4 System Board - P/N 400613-002.

Bare ABRD36 system board does not include DIMM, Boot Loader, Disk On Chip

Battery, CF Daughter Card and Processor heatsink. The ROHS compliant WS4

system board designated ABRD36-B, (Revision B) is the current replacement

board for the original WS4.

Physically, the ABRD36 system board is a drop-in replacement for the AB28-I

system board, using the same interface cables, DOC, boot loader, CF card, and

DIMMs. If this board replaces the AB28-F or AB28-G system boards, see Chapter

6 to install the LCD and backlight cables with the proper ‘offset.’

• DIMM, 128M SDRAM - P/N 700502-172.

Replacement 128M SDRAM DIMM. Compatible with the AB28 and ABRD36

boards, as well as the KWS4 system board. Not compatible with the LX System

board.
