Processor Core

The processor core consists of an integer unit, cache memory subsystem, and an x87 compatible floating point unit. The integer unit contains the instruction pipelines and associated logic. The memory subsystem contains the instruction and data caches, translation look-aside buffers (TLBs) and an interface to the GeodeLink Interface Units (GLIUs).

The LX800 instruction set is based on a combination of Intel’s Pentium®, the AMD K6® processor, and the Athlon™ Floating point unit, and the AMD Geode™ LX processor specific instructions.

GeodeLink Interface Units

The pair of GeodeLink Interface Units (GLIU0 and GLIU1 in the LX800 block diagram, Figure 2-3) form the heart of GeodeLink architecture. Each features a built-in arbiter that enables dynamic allocation of memory bandwidth, with on-the-fly prioritization.

Internally each GLIU includes seven channels, with channel 0 reserved for the GLIU itself and not considered a physical port. Together, GLIU0 and GLIU1 make up the internal bus comprised of the GeodeLink architecture. GLIU0 connects to the five modules that require high bandwidth, and GLIU1 connects to the five low bandwidth modules.

GLIU0 is connected to modules with high-bandwidth requirements:

•CPU Core

• GeodeLink Memory Controller (GLMC)

• Graphics Processor

• Display Controller

• GLIU1 (GeodeLink Interface Unit 1). GLIU1 is connected to modules with lower bandwidth requirements:

• GeodeLink Control Processor (GLCP)

• Video Input Port

• GeodeLink PCI Bridge

• TFT Controller/Video Output Port (VOP)

• Security Block.

GeodeLink Memory Controller

The GeodeLink Memory Controller provides all of the LX800 memory needs. The GLMC is capable of ha ndling multiple requests for memory data fr om the CPU core, the Graphics Processor, the Display Controller and the external PCI bus via the GeodeLink Interface Units (GLIUs). Contention for memory bandwidth between the various modules is minimized by extensive buffering logic.

Because the GLMC supports the memory requirements of both the CPU core and display sub-system, it is classified as a Unified Memory Architecture (UMA) subsystem.

• The 64-bit DDR SDRAM Interface as implemented on the LX System Board, supports unbuffered DDR 333/400 DIMMs up to 2GB.

• Unified Memory Architecture (UMA), UMA enables up to 2GBps memory bandwidth while using single memory interface. The DDR Memor y array contains both the main system memory and the graphics frame buffer.

GeodeLink Control Processor

The GeodeLink Control Processor is used for software debugging and performance analysis.

GeodeLink PCI Bridge

The GeodeLink PCI Bridge (GLPCI) module provides the PCI interface for the LX800 system. It is comprised of five major sections or blocks, briefly described below.

GeodeLink Interface Block

The GeodeLink Interface Block provides a conversion layer between the GeodeLink Interface Unit 1 (GLIU1) and the Transaction Forwarding Block.

FIFO/Synchronous Block

The FIFO module consists of a group of in-bound and out-bound FIFOs. Each FIFO provides a simple, synchronous interfaces to read and write requests.

Transaction Forwarding

The Transaction Forwarding block receives, processes and forwards transaction requests and responses between the GeodeLink Interface and PCI Bus Blocks. Transaction ordering rules are implemented and write gathering and read pre-fetching are performed as required.

Page 35

Workstation 5 Field Ser vic e Guide 2-7

Workstation 5 System Board Technical Descriptions

LX800 Process o r a n d TFT C on trolle r

PCI Bus Interface Block

The PCI Bus Interface provides a protocol conversion layer between the transaction forwarding block and the PCI bus. The master and target portions of this block operate independently.

The PCI Bus Interface Block impl ement s the logic to generate PCI configuration cycles. The standard mechanism for generating PCI Configuration cycles (as described in the PCI 2.2 Specification) is used.

PCI Bus Arbiter

The PCI Arbiter implements a fair arbitration scheme with special support for the CD5536 companion device. By default it operates as a simple round robin arbiter that rotates three request/grant prioritie s in a circular fas hion.

GeodeLink Interface General Description

The GeodeLink Interface is a non-traditional high bandwidth packetized uni-directional bus for internal peripherals. The GeodeLink architecture connects the internal modules of the LX800 and companion device using the data ports defined by GeodeLink Interface Units. Transactions between GeodeLink Devices and the GLIU are conducted with packets.

The GLIU accepts request packets from masters and routes them to slaves. Similarly, slave response packets are routed back to the master. The bus is non-blocking. Several requests can be pending, but order is not guaranteed. All packets have one source and one destination, broadcasts are not allowed.

The existence of the GeodeLink architecture is generally invisible to the user or even a system programmer. All GeodeLink initialization and support is handled at the BIOS level, and additionally provides a Virtual PCI Configuration Space to abstract the GeodeLink architectur e to industry standard interfaces. Through the V irtual PCI Configuration Space, all GeodeLink devices appear in one PCI multi-function configuration space header on the external PCI bus.

CS5536 Co m p anion Device

CS5536 Companion Device

REF: ABRD88 - Sheets 8, 9 and 10

The CS5536 Companion Device is designed to work with the LX800, a processor with an integrated memory controller. Together, the LX800 processor and CS5536 Companion Device provide a low power, high performance embedded solution for both the Workstation 4 LX and the Workstation 5.

The internal architecture is based on the high-performance GeodeLink architecture that yields high internal speed (over 4 GB/s) data movement and versatile power management.

Communications with the AMD LX800 processor is over the 66Mhz PC I Bus. The Geode Companion device includes many IO functions on-chip. These include:

System Management Bus (SMB) Controller

The SMB is a two-wire synchronous serial interface compatible with the System Management Bus physical layer. On the WS5 system board, the SMB controller in the Companion Device is connected to Ethernet Controller U22, as well as each DDR DIMM socket.

Serial Interface

The CS5536 includes two high-speed industry standard serial ports, configured to support the Customer Display and IDN Interfaces. The UAR Ts are 16550 and 16450 software compliant and support baud rates up to 115.2 kbps.

Real Time Clock (RTC) and CMOS RAM

The companion device contains the equivalent of Motorola MC146818A compatible real time clock. The clock performs two functions. It keeps track of the time and date when the system is not connected to AC power, and provides 242 bytes of non-volatile memory for storing BIOS and system data.

The clock contains separate registers for seconds, minutes, hours, days (both day of week and day of month), months, and years. The RTC operates from a 32.768 Khz crystal and is powered from a 3V lithium battery that can maintain operation for several years.

ATA Interface

The IDE Interface is an ATA-5 specification compatible IDE controller (ATAC). Two devices are supported, using PIO Modes 0 through 4, MDMA modes 0 to 2, and UDMA/66 mode 0 through 4.

Page 37

Workstation 5 Field Ser vic e Guide 2-9

Workstation 5 System Board Technical Descriptions

CS5536 Com p an io n D evic e

The interface provides a variety of features to optimize system performance, including 32-bit disk access, post write buffers, bus master, look-ahead read buffer, and pre-fetch mechanism.

On the WS5 System Board, the CF Card resides on the ATA Interface in socket IDE1.

USB Interface

The CS5536 Companion Device includes four Universal Serial Bus (USB)

2.0 compliant ports, supporting low speed, full speed, and high-speed connections.

Each port supports wake-up events and feature over-current and power control support. The ports can be enabled individually to react to over-current events.

Port 4 supports the USB 2.0 On-The-Go supplement version 1.0 specification, but this feature is not supported on the WS5 system board.

One USB output from the Companion Device is fed to an on-board USB hub controller. See the System Board USB Interface Section for more information.

LPC Interface

The LPC is based on Intel’s Low Pin Count (LPC) specification version

1.0. The controller can convert an internal local bus memory or IO cycle to an external LPC cycle. It receives serial IRQs from the LPC bus and converts them to parallel form so they can be routed to the IRQ mapper and interacts with the Legacy DMA logic to perform DMA between on-chip and off-chip devices.

The LPC interface supports memory, I/O, DMA, and firmware hub based devices.

Audio Codec Interface

The codec interface is AC97 V2.3 compliant and contains support for any AC97 audio codec with Sample Rate Conversion (SRC). The WS5 S ystem board uses a Realtek ALC203 Audio Codec and audio amplifier to drive a pair of internal speakers. See the AC 97 Audio Interface section for more information.

Diverse Device

The Diverse Device is comprised of the legacy PC functionality required for most designs.

Power Management Controller (PMC)

This module is a GeodeLink Device whose functio n is to control all aspects of power management. Power Management is event driven - any action the PMC carries out is predicated on some event. Those events can originate from other GeodeLink Devices, such as the LX800 processor, or from other external sources such as the power button.

The PMC consists of three internal sections: Working, Standby, and Real Time Clock.

o The Working block includes all circuits and functions associated with

the W orking power domain. The primary function of the Wor king block is to transition the system to the sleep mode.

o Standby block contains all circuits and functions associated with the

Standby power domain. The primary function f the Standby block is to control power to the Working domain.

o The RTC block contains the timing circuits required to maintain a real

time clock and calender functions. The R T C block is powered by VBAT, from a board mounted CR2032 battery.

TFT LCD and Back light Interface

The Display Controller (DC)

The DC module is similar to that found in the Geode GX processor line with additional hardware for graphics filter functions. It consists of a memory retrieval system (GLIU0), Graphical User Interface (GUI) block, a VGA interface block, and back-end filter/scaling. The GUI and VGA blocks share a single display FIFO and display refresh memory interface to the GeodeLink Memory Controller (GLMC).

The DC module retrieves graphics, video, and overlay streams from the frame buffer, serializes the streams, performs any necessary color look-ups and output formatting, and interfaces to the Video Processor for driving the display device.

Video Processor (VP)

The VP interfaces with the processor core via a GLIU master/slave interface to provide three main functions, the V ideo Processor, the TFT controller, and the V ideo Output Port (VOP). The VP mixes the graphics and video streams, and outputs digital RGB data to the TFT Controller.

The TFT Controller converts the digital RGB output of the V ideo Mixer block to the digital output suitable for driving a TFT flat panel LCD. The panel interface supports most SVGA TFT panels and meets the VESA FPDI (Flat Panel Display Interface) Revision 1 Specification including the correct power sequencing.

LCD Interface (REF: ABRD88 - Sheets 5, 16 and 27)

Figure 2-6 displays a block diagram of the Workstation 5 LCD and Backlight Interfaces.

LX800 Pixel Data outputs DRGB[23:2] are fed to U29, a THC63LVDM83R LVDS Trans mitter. This device contains four seven-bit parallel-load serial-out shift registers coupled to low voltage differential signalling (LVDS) line drivers. Its primary function is to convert the 28-bits of Low Voltage TTL level pixel, control and clock data from the LX800 TFT Controller into four data streams and a single clock stream. The output of U29 drives LCD connector J8.

The primary reasons for converting the TTL/CMOS level video signals to the LVDS format are reduced noise and cable pin count. The LVDS compatible signals are converted back into Low V olt age TTL/CMOS voltage levels within the LCD Panel.

LCD Panel power sequencing is provided by the VDDEN_VIPSYNC output of the LX800 TFT controller. This signal drives a switch consisting of Q9 and Q10. VDDEN_VIPSYNC does not go active until all system voltages and busses have become stable and the processor is executing instructions.

TFT LCD and Back light Interface

Backlight Interface

The backlight enable signal, DISPEN originates in the LX800 TFT controller. This enable signal is ANDed with

SIO_PWM at U6 to produce PWMBL which

drives the backlight inverter board mounted to the LCD plate. SIO_PWM originates from an unused fan controller (FANPWM2) in Super I/O #1, U8.

Inverter Board power, VCC_BL is supplied by VCC12 through F1 and FB8. A pre-regulator circuit is not implemented on the WS5 System Board.

Configuration Jumpers

A total of three jumpers, one on the system board and two on the inverter board are required to configure the LCD panel type.

System Board jumper J17 is used for LCD Panel configuration. At this time, one of two possible LCD panels may be used. Production started with the Sharp LQ150X1LG45 15” LCD Panel and J17 includes a jumper placed between Pins 1 and 2. Note that Pin-1 faces the rear of the unit. On later units with an AUO LCD Panel is installed, no jumper will be installed on J17.

The Backlight Inverter Board contains a pair of jumpers J4 and J5, factory configured to match the LCD panel installed. The jumper setting is routed through the interface cable to the system board as BL_MOD0 and

BL_MOD1 and fed to a pair of general purpose (GPIO28 and GPIO29)

inputs on Super IO #1, U8. At power-up, the WS5 API reads this pair of bits to determine the LCD

panel type. When it determines the LCD panel type, for example the Sharp, it references the \DOC\HWInf folder and loads the file ‘lxvideo_Sharp.inf.’ This file contains backlight brightness and brightness range values optimized for the Sharp LCD. If the AUO panel is used, the jumpers are set accordingly and the API would load the ‘lxvideo_auo.inf file from the \DOC\HWInf folder.

USB Interf ace

Companion Device

U41, the CS5536 companion device supplies four USB ports. One port, USB0 is fed to IO panel connector CN6A.

The USB1 output drives J9, the USB Flas h Drive Connector.

USB Flash Drive Power Control

In the Windows Embedded CE 6.0 and current WEPOS configuration, the USB Flash Drive is the primary boot device. A pre-boot POST test ensures the device is installed.

However, to provide the flexibility of booting from the CF Card, a BIOS field is available that removes power from J9, the USB Flash Drive connector.

A GPIO signal from U8, Super IO #1 called UDOC_ON is controlled by the ‘Boot Test Image’ field of the Special Configuration screen of BIOS Setup. UDOC_ON drives a switch consisting of Q6 and Q8. The default setting of ‘Normal’ sets UDOC_ON high, enabling the switch and providing VCC5_UDOC to power the USB Flash Drive.

When the Boot Test image field is set to ‘Alternate,’ UDOC_ON goes low, and turns off switch, cutting power to the USB Flash Drive socket.

Using the ‘Reset BIOS to WI NCE or WINXPE defaults’ automatically s ets the Boot Test Image field to ‘Normal,’ to allow booting from the USB Flash Drive.

The USB2 port drives the input of USB Hub U21, a device that adds three US B ports to the System Board. See below.

The USB3 port drives J10. This is a right angle 2x5 connector positioned at the front edge of the system board and accessed through a cut-out in the cage. Currently the optional Integrated Finger Pr int Reade r is connecte d to this port. Future options could also use this USB Port.

CN6 Port Power

U30, an LM3526 Dual Port USB Power Switch handles the power and current-limiting requirements of dual USB connector CN6. The device contains a pair of P-channel MOSFETS (one for each port) with separate enables and fault outputs. In a typical application, current flows from the IN(put) pins through the MOSFET and OUT towards the load.

The device employes a two-stage thermal protection circuit. If the internal temperature is greater than 150°C, both MOSFETs are turned off and the fault outputs, FLAGA# and FLAGB# go active. These outputs have a 1 ms delay to prevent false over-current reporting from the in-rush current caused by hot plug events. Shorted switches will continue to cycle off and on, due to the rising and falling die temper ature, until the s hort is removed.

AC 97 Audio Interface

The AC’97 architecture provides for data transfer through individual frames transmitted in a serial data stream. A Time Division Multiplexed (TDM) scheme is used to allow multiple input and output streams as well as access to the internal control registers. Each frame is divided into 12 out going and 12 incoming data frames or slots.

The Table below describes the function of each audio link signal at U9, the audio codec.

Speaker and Line Outputs (REF: ABRD88, Sheet 28)

The speaker outputs of the codec drive U26, a LM4940 ‘Boomer’ series audio amplifier. The LM4940 outputs, SPK_R_OUT and SRK_L_OUT drive system board connectors CN9 and CN10 respectively. The speakers are mounted internally, at the left and right sides of the case.

AUD_PWRON, from a GPIO pin on Super IO #1, is pulled to ground by R405

and fed to the SHUTDOWN input of U9. The BIOS sets AUD_ PWR ON low during a warm or cold boot to reduce speaker ‘pop.’

The LINE_OUT_R and LINE_OUT_L outputs are fed through a low-pass filter to Line Out Jack CN3. The internal speakers remain active when the Line-Out jack is used.

The tra nsmitter in U25 is disabled by ANDing 422_MODE_1# at U20-12 with TRANSMIT_EN1 at U20-13, producing a Low at U20-1 1, dis abling the transmitter i n U25. Transmit data from the UART, TXD3 is routed through level shifter U2 to produce

F_TXD3, and this is fed the D input of U24 and U25.

IDN Receive

The RE# input of each transceiver enables the receiver. RS422_MODE_1 is set high at the RE# input of U24 to disable the receiver. At the same time, 422_MODE_1 is inverted by U11A, enabling the receiver in U25. IDN receive data is gated onto RXD_422# at U20-10, ANDed with

422_232_SEL_1 at U20-9, to produce RXD_422 at U20-8. RXD_422 is ORed with RXD_232 (inactive) to produce F_RXD3 at U4-11

and fed to level shifter U2. U2 is required to interface the VCC5 based IDN interface with the +3.3V based UART in Companion Device U41.

RS422 Termination

The transmit and receive pair is connected to the RS422 termination circuit. In general the RS422 Termination circuit performs three functions: a) provide the proper impedance matching to the communications cable, b) protect the 75176 transceivers from differential-mode transient voltages induced into the IDN cable, and 3) suppress RF emissions originating from the IDN circuitry.

RS232 Data at 3.3V levels appear at the output of UART in U41, and converted to +5V logic by U2. F_TXD3 is fed directly to RS232 Transceiver U18 and on to CN4, the COM4 connector.

RS232 Receive

RS232 Receive data RXD_232# from transceiver U18 is fed to U20-1 where it is ANDed with 422_232_SEL_1 at U20-2 to produce RXD_232. RXD_232 appears at U4-11 (the RS422 interface is inactive) and fed to level shifter U2 and the UART.

Cash Drawer Interface (REF: ABRD88 - Sheet 30)

The system board supports two cash drawers /w standard 4-pin DIN connectors. The cash drawer interface is similar to the Workstation 4 LX system board.

Active Low outputs from the Super IO, CD_OPEN_A# and CD_OPEN_B# are inverted by U11E and U11F before driving the CLK inputs of dual flip-flop U13. The pulse width at the output of each flip-flop is about 70ms, determined by the 1N4148 diodes, 1MΩ resistors, and 0.1µf capacitors.

CD_OPEN_A drives pin 1 of U44, while pin 2, CD_OPEN_DELAY

prevents the drawer from opening when power is applied to the unit.

CD_OPEN_B drives pin 1 of U45, while pin 2, CD_OPEN_DELAY

prevents the drawer from opening when power is applied to the unit. The output of each AND gate drives a SI4410DY N-Channel enhancement

mode field-effect transistor. 1N4002 Diodes D4 and D2 protect each transistor from the back EMF created by the solenoid as the transistor switches off.

The +12V supply, VCC12 conducts through D17 when the +24V circuit is not used through self-resetting fuse F7. If the +24V cash drawer setting in the BIOS is active, diode D17 isolates VCC12.

Cash Drawer Closed Detection

Each drawer contains a SPST switch positioned to detect the drawer open/closed status. The interface is configured to provide a High on

CD_ST_A or CD_ST_B at pin 4 of CN 1 and CN2 when the drawer is open

or not installed and a Low on the status line when the drawer is closed. R21 and R28 ensure each line is high if a drawer is not connected. The cash drawer closed logic can be inverted through a registry setting. See below for more information.

The API checks a system registry key at start-up to determine the drawer open/closed logic levels. HKEY_LOCAL_MACHINE -> UWS4DRIVER

-> CONFIGURATION ReverseCDStatus=0 is the default setting. The default setting causes the API to report the drawer open/closed logic

levels mentioned above. If ReverseCDStatus=1, the API inverts the drawer open/closed logic levels before passing them on to the application software. The registry setting would be changed from the default only if using a cash drawer with reversed cash drawer closed logic.

+24V Regulator (REF: ABRD88 - Sheet 30)

To support cash drawers with +24V solenoids, VCC12 is converted to +24V by U33, a LM2733 boost converter. The output of the converter,

VCC24 is fed to a switch consisting of Q4 and Q5.

The GPIO signal VCC24_ON enables the switch. VCC24_ON is controlled by the ‘Cash drawer voltage’ field in the BIOS Special Configuration screen. See Chapter 2 of the Wor kstation 5 Setup Guide for more information about BIOS Setup.

System Board Hardware Revision (REF: ABRD88 - Sheet 16)

The API as well as the BIOS can determine the hardware revision of the System Board it is operating on. The WS5DiagUtility uses the API to display the hardware revision as part of the System Information screen.

Refer to schematic ABRD88-E, Sheet 16, Grid A5. The interface consists of four traces on the system board, RE V0 - REV3, each connected to ground. The traces are located on the ‘solder’ side of the board. For the REV E board, the

REV2 track is cut and therefore pulled high by R80, while REV0, REV1 and

REV3 remain at ground. This yields a 4-bit value of 0100 and the API and BIOS interprets this as Revision E.

RTL8110S C Etherne t Co n t rolle r

RTL8110SC Ethernet Controller

General Description (REF: ABRD88 - Sheets 8, 14 and 15)

The RTL81 10SC Gigabit Ethernet Controller combines a three-speed IEEE

802.3 compliant Media Access Controller (MAC) with a three-speed Ethernet

transceiver, 32-bit PCI controller, and embedded memory. The device supports PCI v2.2 and Mini-PCI v1.0 bus interfaces for host

communications with power management, and is compliant with the IEEE

802.3 specification for 10/100Mbps Ethernet and IEEE 802.3a specification

for 1000Mbps Ethernet. Functions such as cross over detection and auto-correction, polarity correction, adaptive equalization, cross-talk cancellation, timing recov ery, and error correction are implemented to provide reliable Ethernet communications at high speeds. The RTL8110SC supports remote wake-up, including AMD Magic Packet, Re-LinkOK, and Microsoft Wake-up frames in both the ACPI and APM environments.

PCI Bus Interface

The RTL8110SC implements the PCI bus interface as defi ned in PCI Local Bus Specification Rev 2.3. The RTL8110SC acts as a PCI target (slave mode) when internal registers are accessed, and acts as a bus master when host memory is accessed for descriptor or packet data tran sf er. The PCI Bus operates at 66Mhz.

Link, Speed and Activity LED Control

The RTL8110SC supports up to four LEDs in four operational modes. The WS5 System Board Ethernet connector includes a pair of two-color LEDs integrated into the Ethernet connector, CN8.

LED #1 (on the left side of the connector) serves as a link, speed, and activity indicator at 1000Mbps and 100Mbps speeds.

• When LED #1 is Orange, the link speed is 1000Mbps or 1Gbit. When the LED blinks, this indicates transmit or receive activity on the link.

• When LED #1 is Green, this indicates the link speed is 100Mbps. When the LED blinks, this indicates transmit or receive activity on the link.

• LED #2 (on the right side of the connector) serves as a link, speed, and activity monitor for a 10Mbps connection.

• When LED #2 is Green and LED #1 is off, the link speed is 10Mbps. When the LED blinks, this indicates transmit or receive activity on the link.

System Board Power Distribution

Standby Domain Voltages (REF: ABRD88 - Shts 8, 23 - 26 and 30)

Standby voltages are available when the unit is in the NOPOWER mode. A 100W open frame power supply produces +12V as long as the AC power cable is connected to the unit.

Since the open frame power supply is active, removing the LCD/Touchscreen assembly to check voltages exposes you to hazardous voltages on the power supply heat sinks.

+12V

+12V enters the System Board at J16, Pins 1, 2, and 3 (Sht 23). Input filtering is provided by inductors L8 and L9.

+12V is also fed through FB52 and F10 to Auxiliary +12V Power Connector, J19. An future internal cable will connect between J19 and the IO Panel to make +12V available.

VCC5SB

+5V Standby is produced by REG#1 in U38, a Triple Synchronous Buck Controller. Control input SS_STBY1 is grounded through C264 to enable this regulator as long as +12V is available.

Output load switching is handled by Q21A and Q21B through inductor L6 and cap EC29. The over current trip point is determined by R286/C290 across the TRIP1 input.

VCC3SB

VCC5SB is fed to adjustable voltage regulator U42, a AP11 17_ADJ device

programmed to produce the VCC3SB (+3.3V) output. VCC3SB provides standby power to the Ethernet Controller and Mini-PCI Socket.

VCORESB

On Sheet 25, Precision Micropower Shunt Voltage Reference D21 is connected across V CC3SB to produce VCORESB. This standby voltage is critical. It supplies power to the Power Management Controller (PMC) in the Companion Device U41, allowing it to detect power button switch closures.

VCC1.8SB

VCC5SB drives adjustable voltage regulator U28 to produce VCC1.8SB.

This is fed through FB37 to be labeled VCC_3_25_A. VCC1.8SB supplies power to the analog power input of Ethernet Controller U22.

System Board Power Distribution

Working Domain Voltages

The following describes the Working Domain Voltages. In response to the user pressing the power button or connecting the AC power

cable, the PMC in the CS5536 Companion Device issues the WORKING signal to enable the following voltages.

VCC12

The ‘Always ON’ +12V output is fed to a switch consisting of U22 and Q25 (Sht24) to produce the VCC12 output. When VCC5 (also the working domain, see below) goes active, this turns on Q25, which in turn enables Q22, switching on VCC12.

VCC12 powers many system board components including the audio power

amp, LCD Panel and Backlight Inverter, Memory Voltage Regulator U43 (Sht25), and the RS232 Line Drivers/Receivers.

VCC12 is used on Sheet 30 to generate VCC24V. See the Cash Drawer

Interface for more information about VCC24V.

VCC3

VCC3 is produced by U38 REG#2. The SoftStart input to this regulator, SS_STBY2, is enabled by the WORKING output of the Companion chip.

Q16 inverts this signal to the active low PS_ON# and Q13 inverts the signal to the active high STBY_3V.

Output switching is handled by Q19 and Q20 through inductor L4 and EC28. The over current trip point is determined by R293/C298 connected across the TRIP2 input.

VCC5

VCC5 is produced by U38 REG#3. The SoftStart input to this regulator, SS_STBY3, is enabled by the WORKING output of the Companion chip.

Q16 inverts this signal to the active low PS_ON# and Q12 inverts the signal to the active high STBY_5V.

Output switching is handled by Q18 and Q17 through inductor L5 and EC27. The over current trip point is determined by R297/C302 across the

TRIP3 input.

VCC12-

VCC12- is derived from the SW_3 output of U38, through a combination

of D24, D26, and EC25. VCC12- is used only by the RS232 Line Drivers/Receivers.

VCORE

VCORE is the primary LX800 Processor supply voltage and is active in the

WORKING domain. System Boards up to Revision E use the ALXC800EETJCVD variant of

the LX800 that requires a VCORE of 1.20V. R282 in the VCORE Regulator Circuit is 511Ω.

System Boards Revision F or later use the ALXD800EEXJCVD C3 variant of the LX800 that requires a VCORE of 1.25V. R282 in the VCORE Regulator Circuit is 562Ω.

Working, Standby and System Reset

When power is applied to the Companion Device from a cold start (e.g., the AC power cable is connected to the unit) the external sub-system must assert

RESET_STAND# as Standby power is applied, followed by RESET_WORK#

as Working power is applied.

RESET_STAND# (Reset the Standby Power Domain) is provided by U48, a

LP3470 Tiny Power On Reset Device located on Sheet 8. This device is designed to monitor a specific power supply voltage (in this case VCC5SB) and assert RESET_STB# when the input voltage falls below the pre-programmed threshold of 3.08V. The reset remains asserted for an interval determined by C496. When V CC5SB rises above a threshold of 3.08V,

RST_STB# remains asserted for a period programmed by C496, then

de-asserts.

RESET_WORK# (Reset the Working Power Domain) is generated by U47, a

second LP3470 Tiny Power On Device located on Sheet 26. U47 is also programmed to activate at 3.08V, but the input is tied to VCC3SB . The reset remains asserted for an interval determined by C489. When VCC3SB rises above a threshold of 3.08V, RST_WORK# remains asserted fo r a period programmed by C489, then de-asserts.

In response to the RESET_WORK# and RESET_STANDBY# inputs, the Companion Device asserts RESET_OUT, referred to on the schematic as

PCI_RST#. PCI_RST# is the master system board reset, fed to all major

components including the LX800 processor, BIOS Chip, Ethernet Controller , Super IO #1 and 2, Audio Codec, and Mini-PCI Connector CN11.

All three reset signals are required to start the system board processor.

Workstation 5 Backlight Inverter Board - XBRE38

Functional Description

The Workstation 5 Backlight Inverter Board is mounted to the rear of the LCD Plate. It drives the pair of CCFL tubes in the 15” LCD Panel. The board contains a pair of configuration jumpers used to define the LCD panel type.

Technical Description (XBRE38 - Sheet 1)

The backlight inverter board is based on U1, a Dallas/Maxim DS3992Z-18P Two Channel, Push-Pull CCFL Controller. It utilizes a push-pull drive scheme to convert a DC voltage into the high voltage AC waveform required to drive the backlight tubes. The device supports one lamp per channel with fully independent lamp control and minimal external components.

Each channel drives dual n-channel MOSFET s Q1 and Q2. The MOSFETs are connected between the primary windings of step-up transformers T1 and T2. Each transformer includes a primary center tap connected to V12 (from the workstations VCC12 supply). Circuit operation is outlined below.

Input Supply Monitoring

U1 internally monitors both the inverter power V12, (VCC12), and its own VCC supply V5, (VCC5) to ensure proper operation. Additional fault monitoring includes open-lamp, lamp over current, failure to strike, and over voltage.

Lamp Strike

When both the V5 and V12 supplies are at acceptable levels, the controller attempts to strike (start) the lamps . During lamp strike, U1 boosts the normal lamp operating frequency by 33% to increase the voltage - then slowly ramps up the MOSFET gate duty cycle until the lamp strikes. When current starts following through R15 and R16 to indicate the lamps have struck, U1 returns the operating frequency to normal and enters the Run Lamp stag e.

Run Lamp

In the Run Lamp stage, the DS3992 adjusts the MOSFET gate duty cycle to optimize the lamp current and voltage.

To monitor lamp current, R15 and R16 are connected in series between the CCFL tube and ground. The voltage across each resistor is fed back to the LCM (lamp current monitor) inputs and compared to an internal reference to determine the duty cycle of Q1 and Q2.

Page 67

Workstation 5 Field Ser vic e Guide 2-39

Workstation 5 System Board Technical Descriptions

System Board Power Distribution

Brightness Control

The controller uses a ‘burst’ dimming technique to control lamp bright ness. An analog voltage applied to the BRIGHT input determines the duty cycle of a digital pulse width modulated (DPWM) in the range between 180Hz and 440Hz.

When the DPWM signal cycles high, the lamp is driven at the select ed lamp frequency. This is also called the ‘burst’ period because of the lamp frequency burst that occurs during this time.

During the low DPWM cycle, the controller disables the MOSFET gate drivers, causing current to stop flowing in the lamp, but not long enough to de-energize the lamps. Brightness is increased/decreased by modulating the burst period duty cycle.

PWMBL from the system board supplies an analog voltage to the BRIGHT

input of the controller. The SVM (System Voltage Monitor) input to the controller is connected across resis t or network R18 and R19 and clamping diode D2 to fully de-energize the lamps and reset the controller when the backlights are off.

Operational Troubleshooting

This chapter describes the Workstation 5 boot sequence, provides troubleshooting tips, voltage test points, and a POST error summary for the Workstation 5 System Board, ABRD88.

Workstation 5 Boot Sequence

The following is a detailed description of the Workstation 5 boot process that should assist in troubleshooting a unit that will not start.

1. Connect the AC Power Cable to the AC inlet at the rear of the W orkstation.

If available, connect the workstation to a LAN. Press and release the power button. The Operator LED should start flashing Blue once per second.

Does the Operator LED start flashing Blue with the Power button is pressed?

o If YES, proceed to Step 2. o If NO, see Checking the Power Supply on page 3-15.

2. The Operator LED should flash blue, and at almost the same time, the LCD

backlights should illuminate, followed by the BIOS splash screen with MICROS logo.

Does the BIOS splash Screen appear on the LCD?

o If YES, proceed to Step 3. o If NO, does the system board beeper sound more than once? This

indicates a POST failure. See page 3-14).

o If NO, but the Operator LED is solid Blue. This condition would be

accompanied by other symptoms such as a blank screen, and no beeper. Possible causes include:

o Defective, corrupt or missing BIOS chip, U36. Install P/N

10011 1-01 1 or re-seat the device in the socket. See page 4-22. If the symptoms remain, examine the socket for damage and replace if necessary.

o Defective System Boar d.

If the Operator LED remains solid Blue when you press the power button, this is an indication that the processor is not executing instructions. There are many possible causes for this including (in addition to the BIOS chip and or socket) a missing clock or reset signal, or a missing standby or working voltage.

Comments: The BIOS Splash screen remains visible for about 20 - 22 seconds, During this time, the BIOS initalizes hardware and per forms a POST of major system boar d components. If the POST is successful, the beeper sounds once and the System BIOS Configuration box appears in the upper half of the screen. Next, a series of custom pre-boot firmware applications execute, one of which checks for the presence of the CF Card and USB Flash Drive. Text messages produced by the pre-boot firmware appear direc tly below the configuration box as shown in Figure 3-1.

Figure 3-1: Workstation 5 Pre-b o ot Text Messages

The message, ‘NK.BIN not found on CF’ is not an error, but indicates that a pre-boot firmware application called FlashCE did not find the NK.BIN file on the compact flash card (as part of an upgrade) and is continuing with the boot process. See page 3-12 for more information about how the pre-boot firmwar e applications interact with the CAL to perform platform updates and BIOS updates.

3. Does the unit attempt to boot to the Operating System?

o If YES, and Windows Embedded CE 6.0 is installed, see page 3-8. o If YES, and Windows Embedded for Point Of Service is installed, see

page 3-10.

o If NO - the unit produces a series of beeps, count them or check the

Operational Troubleshooting

Examples include installing or upgrading the stand-alone e7 application or using a USB thumb drive as a back-up device. When attached to one of the shaded ports USB ports during start-up, a thumb drive can be detected and enumerated before the system board USB Flash Drive and cause the BIOS to attempt a boot. If no operating system exists, a ‘UDOC.ID not found’ or ‘Operating system not found’ error appears.

• If NO, the unit does not complete booting to the installed operating system for any reason. A USB keyboard is required for this procedure.

o Clear the CMOS Memory and reset the BIOS Defaults.

System Board Jumper J15 is used to c lear CMOS memory and reset the Real Time Clock (RTC). The procedure can be found below.

o Remove the AC power cable from the workstation. o Figure 3-3, next page. Locate J15 (near the CMOS battery). Move

jumper from the ‘Normal’ position (pins 1-2) to the ‘CMOS R eset’ position (pins 2-3) for a few seconds, then return the jumper to the ‘Normal’ position (pins 1-2). Do not power up the unit with J15 in the ‘CMOS Reset’ position, pins 1-2.

o Improperly programmed, corrupt, or defective USB Flash Drive. Run

Factory Restore. See page 3-22.

o Incompatible CF Card. If using a CF card purchased at the retail level,

there are two possibilities. The CF Card could be ‘DMA Enabled’ or not have the correct partition type.

Some ‘High Performance’ CF Car ds re q ui re D ire c t Memo ry Acc e s s (DMA) signals from the IDE bus to function. However, the CF Daughter Card does not support DMA. This causes the unit to hang as the operating system starts and attempts to retrieve the persistent registry. CF cards formatted as FAT32 (partition type 0x0b) can also cause the unit to hang at start-up. For reliable operation, CF cards shipped with each unit are formatted as FAT16 with a partition type of 0x06.

MICROS continuously certifies the industrial temperature grade CF Cards installed in each unit or made available separately. This type of card is often not available through retail channels.

o Defective System Board.

Operatio n al Trouble s hoo ting

Background Information

To assist in troubleshooting, the following pages provide background information on how the Workstation 5 handles multiple operating system configurations, what the pre-boot firmware applications do and more information about platform updates.

Multiple Boot Configurations

The W or kstation 5 currently supports both t he W indows Embedded CE 6.0 and Windows Embedded for Point Of Service (WEPOS). Each operating system uses a different hardware configuration that is handled through the BIOS Main Menu selections, WINCE or WINXPE. If the boot defaults do not match the hardware configuration, the unit may produce a POST error or may fail to boot.

Windows Embedded CE 6.0

Current Windows Embedded CE 6.0 configurations are equipped with a 256M CF card, 256M USB Flash Drive, and 256M of DDR Memory. All three components must be installed, or the unit will not boot.

The WINCE BIOS defaults assume a CF and USB Flash Drive are installed and configures the USB Flash Drive as the 1st boot device. The ‘Personality Module’ field in the Special Configuration screen is set to ‘CF’ to specify the location of the registry. The ‘Boot Method’ field is set to ‘Windows CE’.

o For example, if the unit is configured to run Windows Embedded CE

6.0 (256M CF, 256M USB Flash Drive and 256M DDR 333 RAM), but the CMOS defaults are set to ‘WINXPE’ the unit will fail to boot because the ‘Personality Module’ field and ‘Boot M ethod’ fields are set incorrectly.

WEPOS

The WEPOS configuration currently uses a 4GB USB Flash Drive, and 512M or 1GB of DDR 333 RAM. A CF Card is not required, but can be installed for additional storage.

Setting the WINXPE defaults removes the CF Card from the ‘DRIVE ASSIGNMENT ORDER’ and ‘BOOT ORDER’ fields in the Basic Configuration Screen and sets ‘Personality Module’ field in the Special Configuration screen to ‘USBFlashDrive.’ This causes the unit to skip the custom CF card POST, but does not prevent the device from appearing as a removable disk drive after WEPOS starts. The Boot Method field is set to ‘Boot Sector.’

o If the unit is configured to run WEPOS, but the defaults are set to

WINCE, the unit will fail POST if a CF card is not installed.

Operational Troubleshooting

Pre-boot Firmware Applications

Regardless of the operating system installed, several custom pre-boot firmware applications execute each time the unit is started. One is custom POST that ensures the Compact Flash Card and USB Flash Drive are installed for the Windows Embedded CE 6.0 configuration. Other pre-boot applications assist in performing platform and BIOS updates or running a Windows CE Factory Restore.

Platform Updates

Windows CE Platform Updates are performed by the combination of the pre-boot firmware applications resident on each terminal and the CAL. The CAL moves platform files from the server to the USB Flash Drive and the Windows CE and BIOS binary image files to the CF Card, and removes all files once the update completes.

The following scenario applies to a workstation running Windows Embedded CE 6.0.

• The Wor kstation 5 Platform Update is downloaded from the MICROS hardware portal and installed on the application or CAL server. The platform update file stops the CAL ser vice, copies updated platform files to the correct CAL Server folders, then restarts the CAL service.

The update is triggered by a file called PLAT FORM.DAT. This text file resides on the server and all client workstations, and contains the current versions of the CAL client, Windows CE, Platform Files and BIOS. A platform update obtained from the HSG portal will include a new PLATFORM.DAT file that specifies the components to update. After the CAL service restarts, it determines that the PLATFORM.DAT file on the server is newer than those on the client terminals and the specified updates start propagating to the workstations.

• If a newer version of CAL client is part of the platform update, it will be transferred to the workstation first and the unit restarted.

• Windows CE starts, the CAL resumes and copies platform files and folders directly to the USB F lash Drive (\DOC ), then c opies the NK.B IN file to the CF card before restarting the unit. When copying platform files from the server to the USB Flash Drive, the CAL script renames all files to ‘new’ extensions. One example of this is UWS4.DLL, the WS5 API. If one attempts to simply copy over this file while the system is live, a file sharing violation will occur.

However, you can rename a .DLL file on a live system without causing errors, so the CAL script copies the new file as UWS4.DLLn, renames the existing file to UWS4.DLLo, then renames UWS4.DLLn to UWS4.DLL. This is repeated for virtually all files in the \DOC folder and sub-folders.

Page 81

Workstation 5 Field Ser vic e Guide 3-13

Workstation 5 Troubleshooting

Operatio n al Trouble s hoo ting

Also during this phase, the CAL script uses the regedit. ex e utility stor ed in the doc\utilities folder to extract CAL, network, and wireless keys from the registry and place them in a temporary file. If an application is installed, other registry settings related to the application are preserved as well.

• The unit restarts and a pre-boot firmware application called FlashCE detects the NK.BIN file and copies it over the existing NK.BIN file in the hidden boot partition and starts it. During this time, the message ‘Updating Operating System - Please Wait’... appears on the LCD before the unit starts.

• The new NK.BIN image starts, the CAL resumes and immediately deletes the NK.BIN file from the CF card. The CAL then enters a ‘clean-up’ phase, restoring the preserved registry keys and removing the ‘n’ and ‘o’ files from the USB Flash Drive before another reboot occurs.

• If a BIOS upgrade is not included in the platform upgrade, the unit boots to to Windows Embedded CE 6.0 and is ready to receive an application through the CAL.

• If a BIOS update is included, the CAL script copies the GRNBELT.BIN binary file along with several support files to the CF card, then forces a restart. A pre-boot firmware application called the Platform Update Facility detects the GRNBELT.BIN file, performs file size and checksum tests on the binary image file, and if successful, flashes the system board BIOS chip. The message “Updating the BIOS - Please do not Remove Power,” during this time.

• When the BIOS update completes, the unit re-starts once again. When the operating system starts, the CAL resumes and removes the BIOS binary and support files from the CF Card.

The example above is a ‘full platform update’ scenario. Because the CAL is script driven, and the PLATFORM update file can specify individual components to update, many variations are possible. A Hotfix mode is also available that can transport a single file (a DLL file for example) or group of files to the unit and restart it. MICROS POS applications are downloaded using a CAL script associated with the application.

CAL32

The WEPOS configuration runs a 32-Bit version of the CAL called CAL32 - it can perform all of the same tasks the CAL on the WinCE platform. However since a typical WEPOS image is several gigabytes, Platform Updates and the WINCE Factory Restore feature are not supported.

CAL32 can be used place the BIOS binary file on the CF card so that the pre-boot application PlatformUpdate can update the BIOS. A CAL32 Hotfix could be implemented to download an updated system file if required.

Workstation Recovery and Platform Update Procedures

There are several methods of restoring a workstation and these are described in the following pages.

Windows Embedded CE 6.0

After replacing the USB Flash Drive and Compact Flash Card, or should the CF card file system become corrupt, the workstation can be restored in one of several ways. Y ou can also use one of the following methods of clearing the CF card to simply switch between one client application or another.

Using WCF

If the WS5 can boot to Windows CE, the Wipe Compact Flash (WCF) Utility can be used. This program is located in the \DOC\ Utilities folder. WCF powers off the unit after completing the operation.

o WCF starts with a warning about clearing the Compact Flash Card.

Press [YES] to continue.

o WCF Version 6.0 presents three options:

o ‘Clear All Registry Settings’ erases the registry files only. All other

files remain.

o ‘Erase Compact Flash’ erases all files on the CF card including

SAR files and e7 totals files.

o ‘Format Compact Flash’ does just that. It formats the CF Card File

Allocation table, clearing all files (and possible corruption) from the card.

The CF Card File system (FAT) in Windows Embedded CE 6.0 can over time become corrupt. CF Card file system corruption is defi ned as inaccurate File Allocation Table (FAT) data that can result in files or folders that are stored or read incorrectly. The amount of corruption and the symptoms it causes varies.

Should corruption of the CF file system occur, it can only be removed through formatting. Using the WCF Utility to ‘Erase Compact Flash’ may temporary resolve the corruption related symptoms, but this does not remove corruption from the FAT and symptoms may return.

After completing the command, WCF power-off the workstation. When the OS starts, it finds that the CF card does not contain a registry, forcing it to use the default registry from the operating system image. The default registry always starts the CAL so it can assist in loc ating an application.

Workstation Recovery and Platform Update Procedures

Using the CAL to Configure a CE Workstation

The Client Application Loader is part of the WS5 CE Platform software that ships with each unit. The CAL Server is distributed with and installed by POS application software.

A registry setting ensures the CAL client starts each time the operating system starts. Windows Embedded CE 6.0 clients use the CAL, and WEPOS clients use CAL32, updated to run in the WIN32 environment. Each version is capable of performing the same tasks.

When the CAL starts, it examines the registry to determine if it has already configured the workstation. When the CAL connects to an application server and downloads an application, it saves CAL, network, server and application related information in the workstation’s registry. This allows the CAL to quickly determine that a n applic ation is installed, remain in the background, and allow the application to start.

Using WCF to dele te the registry, format or erase all files re moves the CAL configuration data so the next time the unit starts, the CAL assumes the workstation is ‘new’ and must be configured.

When the CAL determines the WS5 is not configured, or if you use the ‘Reconfigure CAL’ shortcut, it presents the ‘MICROS CAL Busy. .. Obtaining a List of Available Servers’ window.

After the CAL collects the responding server(s), it presents the MICROS CAL Select Server’ window . This window displays a list of responding CAL severs along with the application type.

The CAL downloads the POS Application

When a server is selected, the CAL presents a list of workstations, pre-programmed in the database. When a workstation is selected from the list, the CAL downloads the POS application and support files, then updates the registry.

Stand-alone CAL

For a W or kstation 5 running the e7 application in stand-alone mode (no server), a modified version of the CAL script is used to load the application from a USB thumb drive attached to an IO panel connector.

Workstation Recovery and Platform Update Procedures

Using Windows CE Factory Restore

For Windows Embedded CE 6.0 configurations, a custom pre-boot firmware application we call Windows CE Factory Restore is available. This is a new tool designed to ease depot maintenance. Should the OS image or platform files become corrupt and prevent the unit from booting, Factory Restore replaces all files on USB Flash Drive and erases the CF Card, returning the unit to the ‘out of box’ factory condition.

To understand how Factory Restore functions, refer to Figure 3-6, below and examine how the USB Flash Drive is partitioned.

Figure 3-6: USB Fla sh Drive Partitions

Starting at the left, Partition 1 is the hidden boot partition, containing the WinCE image file NK.BIN. Partition 2 is also hidden and contains the factory restore files. This includes a duplicate set of platform files, configuration files and folders, utilities and the NK.BIN file. Partition 3 is visible and appears as \DOC in ‘My Devices.’

Figure 3-7 illustrates how WinCE Factory Restore copies the image file and platform files to the correct partitions.

Figure 3-7: Wind o ws CE Factory Restore Operation

NK.BIN is copied from Partition 2 to Partition 1, the boot partition. Platform files and folders are copied from Partition 2 to Partition 3, the ‘\DOC’ folder. Finally, WCF is used to remove all files from the CF Card.

Included in the \DOC folder is the FACRECOV.DAT file. When the unit is shipped, this file contains the GR version of the recovery files. Each time the Factory Restore feature is used, the time and date are appended to the file. The contents of this file can be viewed with the WS5DiagUtility by pressing the [Recovery Image Info] button located on the System Information Sc re e n.

Page 90

Workstation 5 Troubleshooting

Workstation Recovery and Platform Update Procedures

After the unit is placed in the field, subsequent Platform Updates may occur. Currently, when a Platform Update is performed, it updates the files in Partition 1 and Partition 3, but not Partition 2, the factory restore partition. This can result in one or more files in the recovery partition becoming out-of-date.

However, since the primary goal of Factory Restore is to repair a Workstation that previously did not boot, the unit can now be pointed to a CAL or application server with the latest platform updates installed.

Factory Restore Procedure

The procedure to initiate a Factory Restore can be found below and applies to Windows Embedded CE 6.0 unit only.

1. Connect a USB Keyboard to the workstation and power-up. Be sure to

remove any USB Flash or Thumb Drives attached to the IO panel USB ports.

2. The instant the BIOS splash screen appears, press the key combination

[ALT-M]. Note: Some keyboards may not initalize in time to detect this key combination. As an alternative, you can press [Del] to enter BIOS Setup, select the Features Configuration screen, and set the WIN_CE_FACTORY_RESTORE field to ‘Enabled’. Press OK to continue.

o The screen prompts for the system password.

3. If you have not changed the default system password, enter ‘Grnbelt’ (case

sensitive) and press Enter. Press ‘Y’ to confirm.

o If the password entry is successful, the screen returns to the Setup Main

Menu.

4. Select ‘Write to CMOS and Exit’ and press Enter. Press ‘Y’ to confirm.

o The unit restarts and prompts ‘Factory Restore in Progress - Please

Wait.’

5. When the process is complete, the unit automatically restarts. Connect the

workstation to properly configured CAL server to receive the latest platform files and BIOS.

WARNING

Windows CE Factory Restor e deletes all files from the Compact Flash Card. If required, take steps to preserve files on the CF card before running factory restore. If the CF Card is formatted to FAT32 (partition type 0x0b), it will not be erased and may cause Factory Restore to fail.

• Connect a USB Keyboard/Mouse combo and start the ‘TSHARC Calibration’ utility on the desktop.

o Run through the calibration procedure, touching and holding each

target, and releasing when prompted. If touchscreen calibration is not acceptable after completing the procedure, see below.

• Defective Touchscreen glass.

• Incorrect configuration jumper settings.

o The Wor kstatio n 5 supports a Capacitive T ouchscreen, but as of

February 2009 this option has not entered production. If the configuration jumpers are missing or set incorre ctly , the symptoms may appear as a calibration issue instead of a ‘no response to touch.’ message. Refer to Figure 3-9 to ma ke sure the jumper s are set cor rectly. Note that Pin 1 of the jumper block faces the IO Panel.

Workstation 5 Does Not Connect to the LAN

Symptoms: The workstation is connected to the server via the LAN, but communications can not be established.

The RJ-45 LAN connector on the rear panel includes a pair of LEDs to assist with basic LAN connectivity troubleshooting, shown in Figure 3-10 below.

Figure 3-10: Workstation 5 LAN Indicator LEDs

The following discussion applies only to a W orkstation 5 running Windows Embedded CE 6.0.

LED1 combines both the link and connection speed functions in a single device. When LED1 is illuminated, this indicates a valid link while the color indicates the connection speed. The connection speed is automatically negotiated when the cable is connected.

However, this does not mean the Workstation will actually be able to communicate with the server. This is because the link LED operates at the physical layer of the network, and does not require an operating system, network drivers, or TCP/IP address to function.

As long as power is applied, the Ethernet controller in the hub or switch produces ‘Link Beat Pulses’ that are detected by the Ethernet controller in the WS5 causing it to illuminate the appropriate Link LED. Likewise, the Ethernet controller in the WS5 is producing the Link Beat Pulses which are picked up by the Ethernet Controller in the hub or switch, causing it to illuminate its Link LED.

NOTICE

On a WS5 running WEPOS, the RJ-45 LAN Connector LEDs currently do not function and remain dark.

WS5 will not Connect to LAN (Link LED OFF)

Symptoms: When the WS5 is connected to the LAN, but LED1 or LED2 do not illuminate. In the OS, the s ystem tra y network icon (next to the clock) displays a Red ‘X’. Note: the Link LEDs do not function when WEPOS is installed.

• Mis-wired network connector at the workstation or network device wall plate. (this is more likely in a new installation).

• Disconnected or defective or damaged patch cable at the WS5 or network device.

• Defective or damaged in-wall cabling between the WS5 and other network device.

• Defective or non-powered network device. (For example, the WS5 is connected to a network switch, but the device is not powered).

WS5 will not Connect to LAN (Link LED ON)

Symptoms: When the WS5 is connected to a LAN, the Link LED illuminates, but the unit cannot connect to a server.

• The WS5 may need to use DHCP, but a static IP address is assigned. Moving a workstation between various POS Applications can cause this to occur.

MICROS and third party applications use different methods of assigning an IP address to the WS5. Some POS applications may require that the WS5 obtain the IP address via DHCP, while others may require the WS5 be assigned a ‘static’ IP addressees in the 192.100.x.x range.

o To configure the workstation for DCHP or Static IP, from the desktop,

press Start - Settings - Network and Dial-Up Connections.

o Touch the PCI-RTCENIC1 icon twice. o In the IP address tab, make the selection between DHCP or Static IP

and enter a static IP address suitable for the site (normally in the

192.168.x.x range) if required.

o Restart the WS5 after making changes to network settings.
