Overview

Spacelabs Medical’s products are designed and manufactured under good manufacturing practices and in compliance with all applicable regulatory requirements. To ensure proper operation in accordance with these guidelines, this product must be maintained by trained technicians using Spacelabs Medical authorized replacement parts.

This manual applies to the 90385 Universal Clinical Workstation (UCW®) and the 90387 Ultraview® 1700 monitors. The 90385 UCW monitor is a fully Ultraview-compatible bedside or central monitor. It features a 15-inch color display and an infrared touchscreen.

The 90387 Ultraview 1700 monitor combines the module-mounting capability of the 90491 module housing, with the processing and display capabilities of the 90385 UCW. The right side of the chassis is used to house the CPU and I/O PCBAs, while the left side provides two slots for module plug-in. The Ultraview 1700 is capable of driving an external speaker (either amplified or unamplified) or may stand alone, using the internal speaker. The result is a product that provides the same Ultraview Care Network in a single, compact unit, with a separate display. The Ultraview 1700 is primarily intended to function as a compact, two-module bedside or central monitor.

Setup

Pre-Installation Testing

Before mounting the equipment, it is recommended that you first verify its operation as follows:

1. Power ON the unit and let the power-on diagnostics run.

2. Look in the upper-left corner of the display for any diagnostic failures or other system errors. The monitor will start up normally if no unacceptable diagnostic errors occur. Refer to Troubleshooting on page 5-1 for more information on the diagnostics features if the monitor does not start up normally.

3. Insert at least one parameter module for testing purposes.

4. Refer to Preventive Maintenance (PM) Procedures on page 4-3 and complete those procedures.

Mounting

The monitor can be mounted in one of three ways:

Wall Mount — The unit is attached to an adjustable mounting arm that projects out from a wall

track. This mounting scheme is suitable for a bedside configuration.

Pedestal Mount — The unit is securely attached to a flat surface, such as a shelf or an operating room cart.

Roll Stand — The unit can be easily rolled from one location to another.

The 90387 can also be operated unmounted in a free-standing, table-top configuration, or it can be console-mounted.

For installation requirements of the module housing(s), refer to the Module Housings and Power Supplies Service Manual (P/N 070-0680-xx, located on CD-ROM 084-0700-xx).

Base Tension Adjustment (90385)

The 90385 monitor’s base can be adjusted to increase or decrease the tension that allows tilting of the monitor screen. Tension is factory-adjusted for optimum performance and further adjustment is usually not necessary. If adjustment is necessary, turn the base screw clockwise (refer to Figure 2-1) to increase base tension or counter clockwise to decrease tension. Set the tension loosely enough to allow normal viewer adjustments, yet tightly enough to hold the adjusted position.

Figure 2-2: Bedside configuration

Setup

The wall mounting hardware consists of:

Wall Track — The wall track is mounted vertically on the wall with the mounting arm installed in

the track. The mounting arm can be slid up and down in the wall track to the desired height. Wall tracks are available in multiple lengths.

Wall Track End Caps — The wall track end caps are installed on the top and bottom of the wall track to give the track a finished appearance and to prevent the equipment from sliding off the end of the mounting track.

Mounting Arm — The mounting arm projects horizontally out from the wall track and holds the display assembly and module housings. Two types of arms are available: one for a monitor-only installation; the other for installation of the monitor and module housing(s).

Mounting Screws — Mounting screws are provided to install the end caps and to secure the mounting arm at the desired vertical position.

Mounting Considerations

Power supply should be placed no closer than three inches (7.62 cm) to the remote housings to allow sufficient air flow. Install a minimum of four AC outlets.

• The monitor, monitor wall plate, and AC outlet must be located on the same side

of the patient bed. The power cord has a standard length of 10 feet (3.05 m).

Pedestal Mounting (90385)

To attach the pedestal mount to the display assembly refer to Figure 2-3.

1. Verify that the pedestal’s six rubber feet and four retaining studs with retaining rings have not been dislodged during shipping.

2. Carefully place the display on its side. A cushion should be used under the display to avoid scratching the display case.

3. Rotate the display’s round base (if necessary) so that its tick mark points toward the front of the unit.

4. Line up the four retaining studs on the pedestal with the four holes in the display’s round base.

5. Push the pedestal onto the round base and secure it by turning each of the four retaining studs 90 degrees clockwise with a straight blade screwdriver. The studs will lock in place and can no longer be turned.

6. Carefully return the display to its normal upright position.

Console Mounting (90387)

The physical layout and other console characteristics depend on the requirements of the hospital or other institution. It is the responsibility of the institution to define its specific console needs and to design and construct the console according to its specifications.

For this reason, Spacelabs Medical does not supply a pre-fabricated console assembly. Instead, this section provides the information necessary to create a custom console design. In designing the console, the following considerations must be kept in mind.

• Access

The rear of the console must be designed to allow for easy access. The dimensions of the rear access door must allow the 90387 and display monitor to be easily installed and removed.

• Cooling

• The 90387 does not contain a fan.

The console cabinet must be designed to allow sufficient air flow for natural convection.

If the console cabinet is enclosed, one of two cooling methods can be used:

Central Air Conditioning — The console can be connected directly to an air conditioning

cooling duct. The maximum ambient air temperature should be limited to approximately

C, and vented from the console at the highest exit.

Setup

Forced Air Fan — Small, quiet muffin fans rated at 100 cubic feet per minute (CFM) or

equivalent (to be provided by the institution) can be installed. In this case, provide one fan for every central station or two system printers/module recorders that are installed in the console.

UCW and Ultraview 1700 Monitors — Service Manual

The display is the most visible part of the system.

Inside its enclosure are the following assemblies:

• CRT display

• Touchscreen assembly

• CPU, I/O, and interconnect PCBAs

No internal adjustments should be performed on the monitor. Brightness, contrast, horizontal and vertical size, and position of the display area are software-controlled through the touchscreen interface.

Monitor Power Supply

The monitor chassis has an internal power supply that provides AC-to-DC conversion and DC voltage for the CRT display, the touchscreen assembly, and the CPU PCBAs. The I/O and Interconnect PCBAs do not require power.

CRT Display

The CRT display provides the visual interface to the system user.

CRT Specifications:

CRT type: non-interlaced, color CRT with analog RGB and TTL sync outputs

Diagonal size: 15 inches (350.5 mm)

Dot pitch: 0.28 mm triangular dot trios

Light transmittance: semi-tint glass; 57.2% transmissivity

Anti-reflective treatment: anti-static non-glare coating

Light output: 60 foot-lamberts

Display resolution: 1024 × 768 dpi

Vertical refresh rate: 64 Hz

Horizontal refresh rate: 51.584 kHz

Video dot rate: 68.5 MHz

Horizontal screen dimension: 10.5 inches (267 mm)

Vertical screen dimension: 7.8 inches (198 mm)

Touchscreen Assembly

The touchscreen consists of an array of infrared emitters and detectors that surround the CRT screen and generate an array of horizontal and vertical infrared beams over the surface of the screen. Whenever a beam is blocked by the presence of a finger or similar-sized object, the touchscreen circuitry detects the interrupted beam and responds accordingly.

There are no external, manually operated controls associated with the touchscreen. The touchscreen constantly calibrates itself.

3-2

• The monitor will still operate with an inoperable touchscreen. If the touchscreen is significantly out of calibration and unusable, manual calibration must be accomplished using a mouse or keyboard, or via the serial port (refer to Diagnostic Menus on page 5-12).

Theory

Touchscreen specifications:

• Minimum object detected: The touchscreen resolution is 0.28 × 0.28 in (7 × 7 mm). This is the minimum size that can be detected.

• Maximum object detected: The maximum size that can be detected as a single object is software programmable up to 4.1 × 4.1 in (105 × 105 mm). The default is 1.7 × 1.7 in (42 × 42 mm). If a larger object touches the screen, no action is taken.

• Ambient lighting: The touchscreen operates under lighting conditions ranging from a dimly lit room to bright sunshine. Bright sunshine is considered to be equivalent to a 75-watt standard incandescent light bulb held 12 inches (30.45 cm) back from the center of the touchscreen electronics.

Ultraview 1700 (90387)

A typical 90387 system consists of these major components:

• 90387 monitor

• Display

• 90499 or 90491 module housing(s)

The main enclosure is the most visible part of the system.

Inside are the following assemblies:

• CPU, I/O, and interconnect PCBAs

• Backpanel PCBA

• Module housing

No internal adjustments are possible on the monitor.

Monitor Power Supply

The main enclosure does not include an AC-to-DC power supply. AC-to-DC power conversion is provided by an external DC supply. The external supply provides the monitor enclosure with

VDC. The 90387 includes internal DC-to-DC converters to generate appropriate operating

18 voltages from the 18-volt supply.

Display

The display provides the visual interface to the system user. The 90387 must be used with an external display that is sold separately. Spacelabs Medical has medical-grade and non-medicalgrade displays available.

UCW and Ultraview 1700 Monitors — Service Manual

Main CPU

The UCW/1700 uses a 50-MHz version of the Motorola MPC860 processor.

The following are some of the special 860 features:

• PowerPC core processor unit

• 4 K instruction cache

• 4 K data cache

• Memory management unit with instruction and data TLBs

• Watchdog and event timers

• Interrupt controller

• Programmable chip selects and a DRAM controller for memory and peripheral support

• An internal shared memory and RISC engine, which together perform embedded peripheral support functions and emulate DMA channels

• Six high-speed dedicated serial peripheral ports

• 64 programmable I/O ports

Memory

Flash, DRAM, and SRAM memory are all on the local 860 bus. NVRAM is on the ISA bus.

Flash Memory — Two banks of flash memory are connected to programmable chip selects 0 and 1. Flash memory is used for code storage and is fast enough so that code can be directly executed out of flash. This memory may be in-circuit programmed. The flash is mounted on a socketed DIMM. The DIMM can hold from 2 to 16 Megabytes, with 4 being typical.

DRAM Memory — Four banks of DRAM are connected to chip selects 2, 3, 4, and 5. All DRAM is 3.3V EDO. The DRAM is mounted on two socketed DIMMs. From 4 to 32 MB of DRAM can be installed, with 8 being typical. The application program is copied from flash to DRAM upon boot up and is executed from DRAM.

SRAM (GDS) Memory — 256 KB of DRAM are connected to chip select 6. This SRAM holds up the global data system (GDS) data. It is typically held up through power interruptions by a super cap for more than one day.

NVRAM Memory — NVRAM is discussed in the ISA section.

MPC860-PCI Bridge

This is a Spacelabs Medical-designed Field-Programmable Gate Array (FPGA), which implements a bus bridge between the MPC860 processor and the PCI bus. The 860 accesses all PCI and ISA devices through this PCI bridge.

The main functions provided by the MPC860-PCI Bridge:

• Allow the 860 processor to access memory, I/O, and configuration address spaces on the PCI bus.

• Allow PCI peripherals, via their bus mastering capability, to access DRAM and SRAM memory installed on the 860 processor bus via the 860’s bus mastering capability.

• Support programmable chip selects similarly to the 860 CPU for PCI bus-initiated transactions.

• Convert big endian to little endian and vice versa. The PCI bus is little endian; the 860 bus is big endian.

• Perform PCI bus central arbiter function.

• Perform 860 processor bus arbitration.

3-6

Theory

Video

Video is implemented using Chops 69000 VGA controller with 4 MB of internal RAM that resides on the PCI bus.

The RGB analog signals are buffered and fed to the CRT display and to two VGA connectors. The Hsync and Vsync signals also go to the VGA connectors. The composite sync signal goes to the display.

Ethernet

A Digital 21143 PCI-based Ethernet controller provides the network interface. It is able to support both a 10-megabit and 100-megabit Ethernet; however, only a 10-megabit Ethernet is used at this time. This chip directly attaches to the PCI bus and uses a transformer/filter and several passive components to attach to 10BaseT Ethernet.

ISA Bridge

The ISA bridge connects the PCI bus to an ISA bus and to the components on the ISA bus.

The bridge chip (Intel 82371) also contains several useful support functions:

• Seven DMA channels usable by peripherals on the ISA bus

• Three counter/timers

• Three chip selects

• IDE controller

The bridge and ISA bus components are collectively referred to as the ISA subsystem. This subsystem is used for less performance-critical peripherals, specifically, audio, wireless LAN, NVRAM, real-time clock, keyboard, mouse, EPP port, and I/O buffers.

Audio

The audio subsystem is based on a Crystal Multimedia Codec. This chip is capable of supporting simultaneous stereo in and out in a WAV-type format. It is programmable in terms of analog gain, data formats, and data sample frequency. An audio amp is used for the internal speaker, and opamp buffers are used to drive the line-out connector.

Non-Volatile RAM/Real-Time Clock

The NVRAM and real-time clock reside on the ISA bus. Both functions are implemented with a Dallas Semiconductor DS1644 Nonvolatile Timekeeping RAM.

The NVRAM chip contains the following functions:

• A 32 K × 8 static RAM.

• A time-of-day clock, which overlays the uppermost 8-RAM addresses.

• An integrated lithium battery with a 10- to 20-year lifetime.

• An integrated clock crystal with ±1 minute/month accuracy.

• Power-fail circuitry to protect the clock and RAM during power down.

The NVRAM is used to hold sysgen values, error logs, and other miscellaneous system data. The real-time clock keeps track of time while the unit is ON or OFF. An enable bit in the ISA bridge chip must be set to enable writing to the NVRAM. The device is socket-mounted for easy replacement.

3-7

UCW and Ultraview 1700 Monitors — Service Manual

Keyboard/Mouse Interface

The keyboard and mouse interface is implemented with the Intel 82C42PE programmable interface chip on the ISA bus. This device comes pre-programmed with a Phoenix keyboard/PS-2 mouse BIOS.

EPP Port

A 78C36 device on the ISA bus implements an IEEE 1284, Level 1 electrically-compliant, bidirectional enhanced parallel port (EPP). The hardware includes a 16-byte deep FIFO and can use ISA DMA for data transfers. The software is responsible for many functions of the port, including mode negotiation, RLE compression (decompression can be done in hardware), as well as the detailed implementation of several of the communication modes. Refer to the IEEE 1284-1994 standard for detailed requirements of the port. This function is not currently supported.

ISA I/O Buffers

These latches and buffers interface miscellaneous low-frequency status and control signals to the ISA bus.

SDLC Interface

The SDLC interface is the communications interface to Spacelabs Medical modules, which supply patient data to the system.

Ultraview monitors communicate with the external module devices via the SDLC connector:

• Power is not supplied from this connector. All module power is generated by the DC power supply and is isolated from the monitor.

• The SDLC interface runs at a 1.892352-MHz frequency. This is divided down to generate a 448-Hz sampling rate. The SDLC communication task has a built-in program that retrieves the data from the bus, assembles it into a packet format, and provides it to the CPU.

• The SDLC clock signals are sent by the SDLC interface and are used to drive the external SDLC bus and modules. The SDLC data signals are bi-directional and can be used both to transmit and receive data from the intelligent modules.

Nurse Alarm Output

When an alarm sounds, a relay that is connected to the nurse alarm connector is activated. When this connector is connected to an external nurse alarm light/buzzer, the light/buzzer will activate when an alarm occurs.

Clock Distribution

The clock distribution system is designed to provide low-skew clocks to the core hardware operating off of the MPC860 and PCI busses. Additional, lower-tolerance clocks are needed in other peripheral areas.

A Motorola PLL-based clock driver chip is used to provide a low-skew clock distribution system and several optional operational configurations. This provides clocks to all of the PCI devices under

1.0 ns of skew, including wiring delay variation. The MPC860 and FPGA clock skew falls within this

specification also. The device can be pin-strap programmed for various clock frequencies including 25, 33, and/or 50 MHz.

3-8

Theory

These clocks are used for specific peripherals and are generated at various locations on the PCBA.

• 20-MHz clock for Ethernet

• 24.6-MHz clock for audio codec

• 16.9-MHz clock for audio codec

• 12-MHz clock for keyboard/mouse controller

• 14.3-MHz clock for the PCI/ISA bridge and SVGA hardware

• 11.354-MHz clock divided to 1.89 MHz for SDLC

• 68.5-MHz and 34.25-MHz clock for the SVGA hardware

• 8.33-MHz clock for the PCI/ISA bridge and ISA bus

Hardware Reset

The hardware reset originates from the MAX695 power supervisor IC. The supervisor IC keeps the 860 PORESET input asserted (thereby keeping the CPU from running) when the system voltage is less than 4.65 V. Once the system voltage exceeds 4.65 V for 200 ms, the supervisor IC releases the 860 PORESET input, allowing the CPU to boot. The 860 generates two reset outputs, HRESET and SRESET. HRESET is buffered and is used to reset all PCI devices and most other major devices on the PCBA, including ISA devices. (ISA devices, however, can also be individually reset under software control by writing to one of the ISA latches.)

Software Reset

To cause a software reset, the 860 processor causes a unrecoverable situation by first disabling its internal machine check interrupt and then forcing a machine check by accessing unmapped address space, causing the CPU to reboot.

3-9

UCW and Ultraview 1700 Monitors — Service Manual

Power Failure Operation

The power supply within the monitor chassis provides a digital PFAIL signal to the CPU PCBA to indicate that a power failure condition is imminent. This signal is asserted by the power supply if its AC input power fails for more than one cycle or if the monitor is switched OFF. This signal is provided through a power supervisor IC to the MPC860 as an interrupt, causing the processor to take immediate power failure action.

The power supply will continue to provide DC power to the CPU PCBA for a minimum of one millisecond after the power failure condition is detected. The host processor must complete all power failure actions during this time.

Hard Reset Configuration Word

At the rising edge of hard reset (HRESET), the 860 processor samples the rstconfg pin. The 860 processor has this pin tied low, which tells the 860 to read data bus bits 15-0 to determine its basic post-reset configuration. Resistor pullups on the bus pull certain bits high; the others are pulled low by weak internal pulldowns. The 860 is set to read the following:

Bits 15 – 0 = 0000 0110 1000 0010

If any of these bits are stuck in the wrong state at reset, the 860 will not properly boot. The detailed meaning of each bit is explained in the MPC860 User’s Manual.

Interrupts

The MPC860 processor has two on-chip interrupt controllers, one in the System Interface Unit (SIU) and a second controller within the Channel Processor Module (CPM). These handle interrupts on specific input pins of the MPC860. Some interrupts are also routed through the interrupt controller in the ISA bridge.

The CPU PCBA includes several design features intended to reduce EMI effects. The power supply to the PCBA is segmented and heavily filtered to prevent noise propagation from one part of the PCBA to another. All high-frequency signals are driven through series resistors to limit the rise and fall times of these signals, reducing ringing and other EMI effects. The construction of the multi-layer PCBA is such that noisy signals are shielded by power and ground planes.

Boot Sequence Overview

When power is applied, the unit begins the boot up sequence. The following is a highly-abbreviated version of the sequence of events that occurs while the unit is booting.

1. Program execution starts at address 00000100 in flash memory.

2. Key internal and external devices and memories are mapped and enabled.

3. The boot-type value is read from super-cap-backed SRAM. This value is written to SRAM at every power down or self-reboot. The value determines the kind of boot, either warm or cold. Warm booting skips diagnostics and other steps in order to boot as quickly as possible.

4. Key areas of DRAM are tested (cold boot only).

5. The boot code is copied from flash memory to DRAM and program execution resumes in DRAM.

6. More internal and external devices are initialized.

7. Other key memory and CPU tests are performed (cold boot only).

8. The VxWorks kernel is started.

9. Drivers needed for diagnostics and the boot console are installed.

10. Diagnostics are run (cold boot only).

11. Boot logo and the 3-2-1 countdown are displayed (cold boot only).

12. The application code is copied from flash memory to DRAM and executed in DRAM.

13. Much of the above initialization is repeated as part of the application code.

14. The main monitor task, MonitorInit, is spawned and normal monitor operation begins.

Normal Operation Overview

During normal operation, the software does the following:

• Once the unit is booted, it begins normal monitor operation, which involves high-level software subsystem tasks running simultaneously. These tasks interface to other tasks, and all tasks interface to hardware devices via device drivers. The VxWorks kernel is responsible for running tasks based on their relative priority and on other system interrupts and events.

Main Subsystems and Tasks:

• The SDLC subsystem sends packets from the modules to the rest of the system, including Ethernet and GDS, and sends packets to modules.

• The Interpreter subsystem provides modules and keys with “primitives” that are used via table code to create and control the display and action of the various menus and keys. The Interpreter subsystem processes key presses from the user and notifies the Keyboard Interpreter to execute the appropriate table code program. That program uses the Key Display task to redraw the new key state as feedback to the user.

3-12

Theory

• The GDS is the patient database containing parameter data from the modules, including current, general, trend, and waveform data.

• The Remote Interface System handles Ethernet connections to remote monitors and modules. It broadcasts the existence and configuration of the network devices to each other. It enables the user to view remote parameters and to remotely press keys across the network. The Remote Interface System downloads the module table code to remote monitors to create the same human interface on multiple monitors. In addition, it supports the alarm watch and remote view functions and handles multicasted waveform data.

• The Recorder subsystem controls local recorders and network recorders.

• The Alarm subsystem handles alarms notification. Modules send alarm conditions over SLDC, and in response, the alarm subsystem sends alarm messages to the tone, display, record, and network tasks. The module receives messages from the network for alarm watch alarms and from SDLC tasks for local module alarms.

Minor System Tasks and Device Drivers:

• The main subsystems communicate display information to the Display Manager (DM) task. The DM receives display changes from these subsystems and issues the appropriate graphics primitives to update the display through the video device driver.

• The subsystems interface to SDLC via Rx/Tx buffers in memory, driven by a 32-Hz interrupt.

• The Ethernet interface uses dynamic memory for receive and transmit. One Ethernet interrupt occurs for both receive packets and command completes. An Ethernet write command is used for transmitting packets. An “Ethernet-user” task maintains and uses a routing lookup table to switch network packets to the appropriate network driver — the Ethernet device driver or the wireless network card device driver.

• The Recorder subsystem uses these SDLC/Ethernet drivers directly.

• The touchscreen driver and the external keyboard and mouse drivers provide x-y coordinates to the keyboard task for activating the on-screen keys.

• The Tone task is responsible for timing and prioritizing tones from the Alarm subsystem, the Keys subsystem, and other system tasks. It receives commands to turn ON and OFF, to suspend, and to change volume. It also looks up wavetable tones and sends them to the Mixer task.

• The Mixer task mixes the alarm sounds with information tones as needed. Both the Tone and Mixer tasks talk to the audio hardware via the audio device driver.

Patient Lead Leakage Current Tests (Patient Modules)

Before you can perform the Patient Lead Leakage Current Test, verify that the monitor passes the ground resistance and chassis current leakage tests. It is recommended that the equipment be operating for 30 minutes prior to the test to allow thermal stabilization. If a 12-lead patient cable is used with the module being tested, perform the tests using the 12-lead cable.

1. Patient Leads Current Leakage — measure the leakage current between each of the patient leadwires and the ground lug on the monitor back panel. Also, measure the leakage current between all combinations of ECG leads and ground. The current must be less than 10 with the ground connected, and 50 µA with the ground open.

2. Leakage Current to Ground with 50/60 Hz — AC mains voltage applied to leads. Apply AC mains voltage and measure the leakage current between each of the ECG leadwires and the ground lug on the monitor back panel. The current must be less than 50 µA at any line voltage.

Touchscreen Calibration

Touchscreen calibration information is stored in the monitor’s NVRAM. If this information is missing or has been changed, a calibration procedure must be performed on the 90387. A touchscreen calibration may also be performed if the touchscreen is not properly responding when a display key is touched.

A remote monitor with touchscreen capability, connected to a 90387, may be calibrated in one of three ways.

1. Initial Installation — If the touchscreen calibration information is not stored in the NVRAM

and the presence of a touchscreen cable at the J9 port is sensed during power-up, the 90387 will automatically display a calibration screen. The calibration screen will prompt the user to touch the upper-left, upper-right, and lower-right corners of the display for calibration. After calibration, the unit reverts to normal operating mode.

2. Recalibration using the Biomed menu — In the event the touchscreen becomes difficult

UCW and Ultraview 1700 Monitors — Service Manual

Mouse or Keyboard Input

1. Try another mouse or keyboard (there is no setup for the mouse or keyboard, either externally or internally). Cycle the power ON and OFF after changing the keyboard or mouse to guarantee that they are seen by the monitor.

2. If this does not correct the problem, inspect the interconnect board and I/O boards. If any connectors or parts on either of these assemblies appear damaged, replace the damaged assembly.

3. If this does not correct the problem, replace the CPU board.

Audio Line Output (90387 Only)

1. Independently verify the operation of the equipment being connected to the audio line output. Replace it if necessary.

2. If the external equipment is known to work correctly, enable key tones on the monitor and press several touchscreen keys. If tones are not heard through the internal speaker, replace the CPU board. If tones are heard, inspect the interconnect board and I/O boards. If any connectors or parts on either of these assemblies appear damaged, replace the damaged assembly.

3. If this does not correct the problem, replace the CPU board.

Monitor Diagnostics

System integrity and performance verification can be conducted by either automated or manual diagnostics that assist in system troubleshooting. Automated “power-ON” diagnostics are performed at each power-ON. If desired, extended diagnostic testing may be performed manually following manual initiation during system power-ON. Some power-ON tests are not available in the extended diagnostics and vice-versa.

Power-ON Diagnostics

Power-ON diagnostic tests verify system hardware integrity during each power-ON of a monitor. Most of these tests may also be initiated using the extended diagnostic mode.

The diagnostics initiated at power-ON are:

• CPU (reads and writes control registers and does an internal wrap around of one serial communication controller channel)

• DRAM Read/Write (reads and writes DRAM above 1 MB)

• Real time clock (verifies that the clock is running)

• GDS SRAM (reads and writes all of the SRAM, nondestructively)

• PCI bridge (reads and writes control registers)

• ISA bridge (reads and writes control registers)

• Video (tests the video memory, the video controller, hsync, and blue video signals)

• Ethernet (comprehensive internal wrap around)

• Flash checksum (checksums all of flash memory)

• Touchscreen (tests the touchscreen controller and the IR detector/emitter pairs)

• Keyboard and mouse controller (reads and writes control registers, runs a self test, and checks on-card keyboard and mouse signals)

• Audio (reads and writes control registers in the codec)

5-4

Troubleshooting

Power-ON diagnostics failures are reported in the upper-left corner window of the system startup screen. Refer to System Startup on page 5-9 for more information.

Extended Diagnostics

Extended diagnostic tests can be manually initiated only during system startup. The kinds of tests and features available in the extended diagnostics are:

•Power-ON tests.

• Interactive tests and read/write memory tests that are not appropriate during power-ON diagnostics.

• Touchscreen calibration and data dump utilities.

• System data dump and system reset utilities.

The diagnostics menus allow most of these tests to be run individually or all at once. If Loop mode is activated, a test(s) can be executed in a continuous loop. If Halt On Error mode is activated, then the looping stops when a diagnostic failure is detected. To avoid false failures, do not use the touchscreen, mouse, or keyboard while the diagnostics are executing.

For detailed information on the extended diagnostics and how to run them, refer to System Startup on page 5-9, Boot Menu on page 5-10, and Diagnostic Menus on page 5-12.

Diagnostic LED

If during the boot process the CPU determines that it cannot continue to boot, the CPU will stop booting and repeatedly flash an error code on a diagnostic LED. The diagnostic LED is located in the center of the CPU board and is visible by looking through the ventilation holes above the SDLC connector on the back of the unit.

During the boot process, the LED normally flashes on about once every four seconds to indicate that it is working. If the CPU cannot boot, the LED flashes an hexidecimal error code with the most significant character first. Leading zeros are not displayed. Each character is represented by a series of short flashes that count up to the character value (for example, two flashes = 2 hex, fifteen flashes = F hex, etc.). A zero character is indicated by a long flash. Each character is separated by a short pause. After the error code is completed, the LED pauses for about four seconds before repeating the error code. Error codes and their meanings are described in the following section.

Monitor Fails Power-ON Diagnostics

Troubleshooting Method 1: Using the Touchscreen

1. Display the Diagnostic menu.

The Diagnostic menu is activated using the mouse. Left-click followed by a right-click during the “3-2-1” countdown.

2. Click the test parameter key that retests the previously-indicated failure.

Upon verification of the failure, a message provided by the monitor directs you to the field replaceable unit that failed.

System Startup

When the unit is first powered ON, the following three-window system startup screen is displayed.

This window displays any diagnostic

failures and other system errors

during the boot process.

This window is reserved for future use.

This window displays basic system configuration

and booting status during the boot process.

The Boot menu and Diagnostics menus are also shown here.

Boot Menu

The Boot menu allows access to several basic configuration menus and functions of the monitor, including extended diagnostics. The Boot menu is activated during system startup and can be controlled using either the touchscreen, mouse, keyboard, or terminal (or a computer with terminal emulation software) connected to the serial port. All text displayed on the screen is also output on the serial port.

The Boot menu can be accessed in the following ways:

• With a touchscreen, place a finger into the two lower corners of the display during system startup when you see the “3-2-1” countdown.

Figure 5-2: Finger placement to initiate boot menu using the touchscreen

• With a PS2-style mouse, simultaneously click the left and right mouse buttons on the “3” of the “3-2-1” countdown.

• With the keyboard or terminal, press CTRL+D during the countdown (the terminal’s serial port should be set to 9600 baud, no parity, 8 data bits, and one stop bit)

• Do not move the mouse or cause input through the keyboard during power ON

until the “3-2-1” countdown. Doing so will cause diagnostic arrows with the keyboard or mouse controller.

5-10

After initiation, the following main Boot menu appears.

? - help @ - boot (load and go) p - print boot params c - change boot params g - go to address m - memory functions... e - print fatal exception N - set node id D - run diagnostics... z - zero NV ram E - error log functions... b - burn flash...

v - set video characteristics (90387 only)

T - Touchscreen calibration *
