back also requires factory realignment.)
8K Series ProPalette Factory Optimization
All 8K Series ProPalette film recorder models (8035, 8045, 8067) are factory-optimized
and matched to a specific camera during manufacture. Using a Polaroid Digital
Alignment Station at the factory assures that image quality, sizing, sharpness, location,
geometry and color saturation are all at peak level. These critical alignments result in
ideal match-ups between recorder and camera.
This process results in a film recorder with the highest level of precision which achieves
unprecedented image quality right out of the box. Each ProPalette model produces higher
resolution images than other film recorders in its product category.
Film Recorder Optics
The 8K Series ProPalette film recorders have a high-resolution, precision 7-inch CRT
with a proprietary anti-reflection and anti-static coating to render superb image sharpness
and purity. They also utilize custom optics with six element glass lenses and glass
dichroic filters to minimize spot size and maximize color saturation.

Page 14
8K Series ProPalette Repair Manual Description
Electronics
Auto-Luma /Auto-Chroma digital circuits automatically adjust brightness, luminance and
color balance. Digital geometry correction provides exacting straight lines and perfect
circles and eliminates pin cushioning, barreling and keystoning. Dynamic focus circuits
adjust the focus of the electron beam to assure consistent sharpness and clarity over the
entire image area. The system’s electronics adjust the focus of each image on the CRT
and use custom lookup tables for horizontal and vertical planes.
The 8K Series ProPalette provides 8000-line, continuously variable resolution for
recording images in their native, scanned resolution. This eliminates the image
degradation exhibited at lower resolutions and the need for time-consuming image
interpolation and decimation. The 8K Series ProPalette models are also designed for fast
printing: exposing a 35mm image at 4096 dpi requires less than 60 seconds.
The finished product is a 24-bit image with 36-bit color depth per pixel and 16.8 million
colors drawn from a palette of 68 billion colors. This results in smooth, ramped
backgrounds and accurate colors.
System Status LCD Panel
A 20-character, two line interactive LCD panel on the film recorder guides the user
through setup and also provides system status information during operation. A control
panel with a push-button menu system allows the user to send commands to the recorder.
Status/command functions are provided in choice of five languages and include:
• Storage of all setups in permanent
memory
• Image pixel dimensions displayed during
green exposure
• Firmware version and update status
• Automatic load/unload film status
• Detection of film jams/mis-thread
• Frames counted and frames available for
exposure
• Red/green/blue pass in progress
• Rewind film/advance film/remove
film/abort exposure
• Pacing indicators and waiting for host
warnings
• Previous error storage and information
retrieval
• Circuit board version information
• Unit serial number
• Calibration in progress
• SCSI ID, SCSI terminate settings
• Leader/no-leader selection
• Out-of film detection by end of roll or
frame count

• Centronics parallel
• Synchronization IEEE 1284 style
• SCSI-1
• RJ-11 serial (available to service personnel only)
Figure 1-4. ProPalette Ports
Software and Interface Accessory Kits
The software provided in the Windows and Macintosh accessory kits is designed
specifically for ProPalette film recorders. Accessory kits are purchased separately.
ColorTune software matches the image seen on the computer monitor to the final image
created by the Propalette. This allows the user to perform more accurate previewing when
making adjustments to color and tone scale. ColorTune also enables the user to customize
film look-up tables to their individual workstation to obtain specific results.
Palette Export, an Adobe Photoshop export plug-in module allows printing directly from
Photoshop to produce continuous tone images quickly and simply.
The recorders can be networked with Palette for Windows (including Windows 95,
Windows 98, and Windows NT) and Palette for Macintosh. These software kits include
RasterPlus drivers.
All 8K ProPalette software has been tested for year-2000 compliance.
Accessory kits also include the appropriate cables for connecting the ProPalette film
recorder to Windows or Macintosh platforms.
The accessory kits are described in more detail in the following sections. For the PID
number associated with each kit, see Table 1-1 on page 17.

Note: SCSI device chains must be terminated once at each end of
the chain. The host adapter terminates one end. You must
terminate the other end. The following figures show three
typical connections.
In Figure 2-8, ProPalette is the only SCSI device and must be terminated. This
example shows external termination using a separate terminator (not
included). The ProPalette may be terminated internally instead (see below).
Connect the SCSI terminator either between the SCSI cable and the ProPalette
or to the second SCSI connector on the ProPalette rear panel.
Figure 2-8. SCSI connection #1
In Figure 2-9, ProPalette is the last device in the SCSI chain and must be
terminated. Figure 2-9 shows external termination using a separate terminator
(not included).
Figure 2-9. SCSI connection #2
The ProPalette may be terminated internally instead. (See “Terminating the
ProPalette Internally” on page 28.) Connect the SCSI terminator either
between the SCSI cable and the ProPalette or to the second SCSI connector on

Connection Tips
• When you connect or disconnect a SCSI device, make sure all SCSI devices have their
AC power switched OFF.
• Always make SCSI connections firmly, connecting the clips or tightening the screws
that secure cables and terminators. Most problems with SCSI devices are connection
problems along the SCSI chain.
• Some devices, such as the ProPalette, have two SCSI ports. The cable can be connected
to either port without affecting the performance of your equipment.
• Each device on a SCSI chain must have a unique SCSI ID number. These numbers are
described in the following section.
• Wherever a 50-to-50 pin cable is required, be sure to use a cable which meets the
SCSI-2 specification, such as an Apple cable.
• If you are using a PC, the ProPalette can be connected to two host computers at once;
one via the parallel connector and one via the SCSI connector. The recorder will image
in the order the signal is received.

Locking the Film Type Via the Keypad
The film type must always be selected in the software and it must match the film loaded
into the recorder to ensure proper color balance and exposure. If the recorder is on a
network, it may be inconvenient for remote users to confirm which film type is currently
loaded into the recorder. If so, you can “lock in” the film type you have just loaded using
the keypad. Doing so will prevent users from making exposures on the incorrect film type
(an error message will alert the user).
When the film type is “unlocked” (not selected via the keypad), no error message is sent.
In this case, remote users should check which film is loaded before imaging.
To lock the film type:
1. Press the Escape key to reach the Change Setup menu.
2. Press the Down key until “Lock Film Type?” is displayed. Press the Select
key. “*Unlocked” or the name of the currently locked film is displayed.
3. Press the Down (or Up ) key to display the film type that is currently loaded.
Or, select Unlocked to allow any film type to be selected in the software.
4. Press the Select key to enter the selection. An asterisk (*) will appear next to
your selection to indicate it has been selected. Press Escape twice to return to
the Ready message.
40
Page 41
8K Series ProPalette Repair Manual Hardware Operating Information
Locking the Camera Type via the Keypad
A camera-locking function has been added to the 8K Series ProPalette LCD/keypad
menu. This function allows the operator to bypass the camera auto-sense and manually
select the camera installed on the system.
The available menu options are:
• Auto Sense (default)
• 35 mm
• 4 x 5
• 6 x 7
• 6 x 8
• Bulk 35 mm (see the following section, “Bulk Camera Support”)
To lock the camera type:
1. Press the Escape key to reach the Change Setup menu.
2. Press the Down key until “Lock Camera Type?” is displayed. Press the Select
key. The name of the current selection is displayed.
3. Press the Up or Down key to display the desired camera type.
4. Press the Select key to enter the selection.
5. Press Escape twice to return to the Ready message.
Bulk Camera Support
The 8K Series ProPalette models (8035, 8045, 8067) support the bulk camera back
manufactured by Double M. The ProPalette automatically detects the bulk back and
displays “35-mm bulk” when it is attached. To expose bulk images, use the standard
35mm drivers and film tables.
The bulk camera can also be selected by manually setting the camera type to “Bulk 35
mm” as described in the previous section.
Leaving a Film Leader
It is more convenient to process Polaroid Polachrome HC instant 35mm film if a short
length of film (a “leader”) remains extended from the cartridge after the roll is exposed
and rewound. To set the camera back to leave a leader after rewinding, do the following:
1. Press the Escape key to reach the Change Setup menu.
41
Page 42
8K Series ProPalette Repair Manual Hardware Operating Information
2. Press the Down key until “Leave Leader?” is displayed.
3. Press the Select key, then press the Down key to display “Yes.”
4. Press the Select key to enter the selection. Press Escape twice to return to the
Ready message.
Note: Select No under “Leave Leader?” when reloading
conventional 35mm film to rewind the film completely into
the cartridge.
Making Exposures
Once you have loaded the film, the Ready status message will be displayed on the
message panel. You are now ready to begin initiating exposures from the software. (Be
sure to select the correct film type in the software.)
Before an exposure is started, "READY" appears on the first line of the LCD display.
When a 35 mm camera is mounted, the second line of the LCD display alternates
between the camera name with its serial number and the frame count status. If any other
camera is mounted, the camera name and its serial number appears on the second line.
Note: The displayed camera serial number was stored in flash
memory at the factory when the camera was matched to the
ProPalette. The ProPalette does not read the camera serial
number from the camera.
When you begin your first exposure, the unit may do a brief calibration routine first (the
message panel will display “Calibrating.”).
During the exposure, the message panel displays information about the process. The top
line indicates the color is being exposed and the line count being exposed. The second
line of the display changes and depends on the color is being exposed. During the RED
exposure, the second line displays the selected film type. During the GREEN exposure,
the second line displays the image resolution. During the BLUE exposure, the second line
displays the current frame count.
After each exposure, the panel will count down the frames available (for example, “23
Frames Left of 24”). When the last exposure is finished, the message panel will display
“Out of Film.” Remove the exposed film as described in the following section.
Note: When you turn off the recorder with a partially exposed roll
loaded, the recorder keeps the status information in
memory and will redisplay the correct frame count when
you turn on the recorder again.

When you are finished exposing a roll of 35mm film, the camera will automatically
rewind the film. The message panel will then display “Out of Film.” Open the front door
of the recorder, open the film door, and remove the film cassette. The film should be
completely rewound into the cassette unless the film leader option has been selected as
described on page 41.
Rewinding a Partially Exposed Roll
To rewind a partially exposed roll of film, press the Escape key to display the Change
Setup menu. Press the Down key until “Rewind Film” is displayed. Press the Select key.
The film will rewind, and the message panel will display “Out of Film” when done.
Remove the film.
Note: Do not try to reinstall a partially exposed roll of film.
Advancing Film
If you need to advance film (leave unexposed frames) during a session, press the Escape
key to display the Change Setup menu. Press the Down key until “Advance Film?” is
displayed. Press the Select key; the film will advance one frame. To advance the film by
more than one frame, repeat this sequence the desired number of times.
Note: This option is useful if a power failure occurs during an exposure.
Advance the film by one frame, then reshoot the image on the next frame.
Or, if you accidentally opened the film door when a partially exposed roll
was loaded, advance the film by a few frames to bypass the light-fogged
area of film.
Removing and Replacing the 35mm Camera Back
To remove the 35mm camera back:
1. Open the front cover of the recorder.
2. Move the locking lever to the unlocked ({) position (Figure 2-41, left).
3. Carefully pull the camera back straight off (Figure 2-41, right). Replace the
lens cap, which is stored in the front cover, while the camera is not in use.
Figure 2-41. Removing and replacing the camera back

8K Series ProPalette Repair Manual Hardware Operating Information
To replace the camera back:
1. Remove the lens cap and store it in the holder in the front door.
2. Be sure the locking lever is set to the unlocked ({) position.
3. Push the 35mm camera back gently but firmly onto the mounting plate so the
positioning pins fit in the holes, and so the edge connector fits snugly into the
slot in the recorder. Turn the locking lever to the locked (z) position.
Enhanced Information Display
On the 8K Series ProPalette models, the current film table name appears on the LCD
display during the red exposure to help prevent film table selection mistakes.
The actual resolution (in pixels) also displays during the green exposure. This feature
demonstrates the unique ProPalette variable resolution capability (i.e., bitmap images
exposed at their native resolution without time consuming and image degrading pixel
interpolation or re-rendering).
Artifact Warning Indicators
On the 8K Series ProPalette models (8035, 8045, 8067), the LCD warns when the host
computer is unable to maintain the steady supply of pixel data needed for artifact-free
images. (The artifacts are thin dark horizontal lines, particularly noticeable in pastel
regions of the image.)
The warning sign appears in front of the line number during the exposure and remains
visible until the next image. The symbol displayed indicates the delay time in the data
and the likely impact on the image as follows:
Display Wait Time
underscore ("_") 200 msec May produce artifacts
dash ("-") 400 msec [TBD]
equal sign ("=") 600 msec Likely to produce artifacts (thin, black,
horizontal lines)
If artifact warnings occur, the operator should do one of the following to avoid artifacts:
• Turn on "buffer to disk" if the software driver supports it.
• Shut down unnecessary applications competing with the driver.
• Move images from a heavily loaded network to a local drive.
Impact
• Rotate, crop, or scale before starting the exposure.
• Add more memory, disk space , or CPU power to the PC.
• Increase the pacing setting via the keypad or the driver.

8K Series ProPalette Repair Manual Hardware Operating Information
Hardware Configuration Display
On the 8K Series ProPalette models, the diagnostics menu command "Show Power On
Msg?" has added functionality to aid diagnostics during telephone support and service.
This command displays the film recorder model, firmware version, firmware date and
firmware time. After 10 seconds, the ProPalette serial number (if entered during
manufacturing) and the hardware configuration numbers of the three main circuit boards
appear.
High Density Grids
On the 8K Series ProPalette models, high-density grids are enabled. The operator sees an
"initializing" message at startup or when cameras are swapped.
The high-density grids are being calculated and stored in RAM during this time. Note
that the 4x5 camera may require four or five minutes to initialize.
Protecting the CRT and Camera from Dust
Follow these guidelines to protect the CRT and camera from dust:
• Keep a camera back on the unit when it is not in use.
• When the camera back is not mounted on the recorder, use the lens cap
provided.
Cleaning the CRT Face
The CRT inside the recorder has an anti-static coating to help protect it from smoke and
dust particles. But if dust appears on the CRT, clean it as follows.
1. Turn the power off and disconnect the power cord.
2. Turn the recorder on its side.
3. Unscrew and remove the access door on the bottom.
4. Carefully reach in and remove the dust on the surface of the CRT with a dry
cotton swab (Figure 2-42). Avoid touching the filter wheel and filters.
Figure 2-42. Cleaning the CRT face through the bottom access door

8K Series ProPalette Repair Manual Hardware Operating Information
Cleaning the Camera Lens
Remove the camera back and hold it with the lens facing up. Remove as much dirt as
possible with an aspirator, pressurized air, or a camel hair brush, available at a camera
store. If necessary, wipe the lens with a cotton-tipped swab moistened with lens cleaner
(Figure 2-43). Do not soak the swab so that the lens is flooded with cleaner. Examine the
surface of the lens for scratches and replace it if any are found.
Caution: When cleaning the lens, do not use strong detergent
solutions, abrasives of any sort, or aromatic solvents
such as acetone or MEK.
Figure 2-43. Cleaning the camera lens
Testing the Hardware Installation
To verify that the recorder is imaging properly without connecting the unit to a computer,
you can use the keypad to initiate a test image exposure as follows:
1. Remove the 35mm camera to allow observation of the CRT through the lens
opening in the recorder.
2. With the Ready message displayed, press the Escape key to reach the Change
Setup menu.
3. Press the Down key until “Diagnostics?” appears. Press the Select key, then
press the Down key to display “Expose Test Image?”
4. Press the Select key to begin the test exposure cycle, and view the CRT
through the camera opening.
A row of red spots should be moving down the screen, and a horizontal line
should be flashing intermittently. This cycle repeats for the green and blue
filters. (Figure 2-44 shows the image this pattern would create on film.)
Figure 2-44. 8K Series ProPalette test image
46
Page 47
8K Series ProPalette Repair Manual Hardware Operating Information
If you do not see the spots and horizontal line described in step 4, there is a
problem with the hardware or hardware installation. Check your cable
connections before looking further.
If the test was successful but you cannot image from a software package, the
problem could be software-related. Check the software manual or contact the
manufacturer of the application software.
If a loaded 35 mm camera is attached to the ProPalette when the Self Test is
initiated, the shutter opens just prior to the RED exposure and closes at the
end of the BLUE exposure. There is no change to any frame count and the
film must be advanced with the keypad controls. This allows verification of
camera functionality.
Troubleshooting Hardware and Film Probl ems
This section describes symptoms and solutions for problems with hardware setup and use
of the 35mm camera/adapter. Refer to the software manual for troubleshooting software
problems. Also refer to Chapter 4 for additional troubleshooting information.
Black image (film not exposed): The shutter did not open, the lens cap was left on
the camera, or the preview function of the RasterPlus95 has deleted the image file.
Random black spots: Caused by dirt specks on the CRT. Clean the CRT.
Dark, or pale colored horizontal lines across image: Make sure the recorder is
properly grounded (including extensions and multiple outlet strips), use only the
cables supplied with the recorder, protect the unit from bumps or vibrations during
exposure; data wait lines as a result of a slow host computer.
Image too light or dark; incorrect color balance: Make sure the correct film type
has been specified in the software; see the software instructions for details.
Color Balance and Exposure for Negative Film
When using color negative film, color balance and exposure can vary over a wide range
due to the variability of processing and printing at the processing lab. If exact color
matching is important, shoot the test image at the beginning of each roll and have a
custom lab calibrate the equipment to that image for color balance and exposure before
printing the roll. The image is equivalent to an 18% gray card.
Macintosh users: The test image GRAYCARD is in the Print Me Later folder.
PC users: The test image GRAYCARD.TIF is copied onto your hard drive at
installation. Import this file into your application software for imaging.

Activating Monitor Mode
Monitor mode refers to the rudimentary operating system hard-coded into the ProPalette
on-board microprocessor. It provides base level control and communication between the
ProPalette unit and the host computer through the ProPalette serial port.
Monitor mode can be activated by any of three methods: (1) front panel buttons, (2)
digital board jumpers, and (3) LCD menu.
Activating Monitor Mode Via Front Panel Buttons
Note: Monitor mode can be activated via the front panel buttons only on
ProPalette models with digital board 1F5570A Is06 or later
(generally ProPalette models 8035, 8045 and 8067, and ProPalette
7000 and 8000 models with upgraded digital boards). This method
also works with earlier digital boards if EPROM U103 has been
upgraded with the ProPalette ROM v548 P/N 102423.
To activate Monitor mode via the front panel buttons:
1 Turn the ProPalette power switch to off.
2 While pressing and holding the scroll up and scroll down buttons, turn the
power switch on.
3 Release the scroll up and scroll down buttons.
Note: This method also disables the watchdog timer.
To return to normal mode, turn the system off and back on or press the reset button.
Activating Monitor Mode Via Digital Board
To activate Monitor mode via the digital board:
1 Turn the ProPalette power switch to off.
2 Jump J3-6 and J3-8 on the digital board to ground. (All pins along the bottom
of J3 are at ground potential.)
3 Turn the ProPalette power switch to on.
Note: The LCD panel does not operate when you activate
Monitor mode in this manner, so there is no indication that
the mode is active. You must run a terminal emulator for
the serial port to verify that the EEPROM has control.
Return to normal mode by turning the system off, removing the jumpers, and turning the
system back on.
51
Page 52
8K Series ProPalette Repair Manual Hardware Operating Information
Activating Monitor Mode Via LCD Menu
Note: The LCD menu cannot be used when the ProPalette
firmware is corrupted (only a blinking cursor appears on
the LCD display when the unit is powered on). In this case,
you must activate Monitor mode via the front panel buttons
or the digital board as described in the previous sections.
To activate Monitor mode via the LCD menu:
1 Turn the ProPalette power switch to on.
2 Select Diagnostics from the top level LCD menu.
3 Select Go To Monitor Mode from the second level menu.
The LCD panel displays “Film Printer in Monitor Mode.”
Return to normal mode by pressing the reset button on the back of the ProPalette unit.
Displaying or Changing the Stored Serial Number
This section describes the use of the host side DOS utility SN.EXE, which displays or
changes the serial number stored in the ProPalette flash memory.
Serial number storage was implemented in the ProPalette with firmware version 564. The
serial number is stored in flash memory and is used by the firmware to define the correct
system parameters based on the hardware configuration associated with the serial
number.
The executable SN.EXE either displays the current serial number and board versions or
changes the serial number.
Viewing the Stored Serial Number and Board Versions
To view the serial number and circuit board version numbers stored in the ProPalette
flash memory, execute the following command from a DOS window:
sn
By default, the utility accesses the COM1 port of the host computer.
The utility’s help file is accessed with the command: sn ?
52
Page 53
8K Series ProPalette Repair Manual Hardware Operating Information
The command displays a report similar to the following:
sn, Reports and optionally sets serial number
Version 564/704
Compiled on Jun 12 1998
The current film printer number is :
serial number = 8A6020H
Analog version = 4
Digital version = 7
Video version = 2
For more information about ProPalette serial number syntax, see “Serial Number Syntax”
in the next section. Board versions are listed on page 103.
Serial Number Syntax
The serial number is made up of six fields:
• Model (P)
• Month of mfg. (M)
• Year of mfg.(Y)
• Sequential count (nnn)
• Product revision (R)
• CRT identifier (C)
These fields are arranged in the serial number as follows:
P M Y nnn R C
The following table identifies the information provided by each serial number field:
Serial No. Field Meaning
P ProPalette model: ProPalette 8000 Plus
M Month of manufacture:
A = Jan D = Apr G = Jul K = Oct
B = Feb E = May H = Aug L = Nov
C = Mar F = Jun J = Sep M = Dec
Y

8K Series ProPalette Repair Manual Hardware Operating Information
Changing the Stored Serial Number
To change the serial number stored in the ProPalette flash memory, execute the following
command:
sn -burn=<string>
where <string> is the serial number to be stored in flash memory.
By default, the utility accesses the COM1 port of the host computer.
The utility’s help file is accessed with the command: sn ?
Viewing and Interpreting the Error Log
The host-side utility, ERRSTAT.EXE, allows viewing of the ProPalette error log for
troubleshooting purposes. For more information about the error log and messages that
can be stored there, see “Error Logging (ERRSTAT.EXE)” on page 99.
Enabling and Disabling the Watchdog Timer
The ProPalette watchdog timer prevents power-on initialization errors. The watchdog
timer is normally on, but must be disabled for performing some service procedures such
as running the Flash Manager utility described on page 153.
The watchdog timer can be enabled or disabled by changing the position of the jumper on
JP501 of the digital board (1F5570A) as follows:
Watchdog timer enabled: Jump pins 2 and 3 on JP501
Watchdog timer disabled: Jump pins 1 and 2 on JP501
The watchdog timer is also disabled when the ProPalette monitor mode is activated via
the front panel keys as described on page 51.

3 Theory of Operation
Design Objectives
The goals of ProPalette design are as follows:
• Reliable
• Easy-to-operate
• Continuous and variable resolution from 512 to 8K
• Fast exposure
• Parallel and SCSI port support
• High image quality (high sharpness, optimized geometry, low
vignetting)
• Optimized manufacturability
Image Quality Objectives
ProPalette design provides high image quality as follows:
Image Quality Parameter Method
Sharpness 7-inch CRT, high voltage focus
Geometry Direct digital control of horizontal and vertical
deflection via D/A converters
Vignetting (dark corners) Direct digital control of cosine4 signal via D/A converter
Manufacturability and Serviceability
In the 8K Series ProPalette models, manufacturability and serviceability have been
improved by eliminating all potentiometers and eliminating the need to perform any
adjustments on the CRT. In addition, a new automatic alignment system determines
optimum geometry settings and focus voltages, factory-matching the camera to the
recorder. After the optimum settings have been determined, the values are stored in the
ProPalette flash memory.
The 8K Series ProPalette models reduce exposure times via the method of exposing each
pixel line in a single horizontal scan instead of multiple horizontal scans.
55
Page 56
8K Series ProPalette Repair Manual Theory of Operation
CPU
ProPalette’s CPU is a V53 (Intel 186 compatible) with a TI DSP. It also has 4 megabytes
of DRAM (expandable to 14 megabytes at the factory), and a field-upgradeable 512
kilobyte flash firmware memory.
Deflection and Geometry Control
Pixel deflection is controlled digitally via a 2D lookup table, 16-bit DAC, sample and
hold and a low-pass filter. Instead of magnets on the CRT yoke, the 8K Series ProPalette
models correct geometry (pincushion) digitally through the 2D, 16-bit lookup table
customized at the factory for each unit and stored in flash memory.
Sharpness Control
The ProPalette provides dynamic focus through a 2D lookup table and a 12-bit DAC. The
lookup table is customized for each unit at the factory and stored in flash memory. The
system also reduces pixel degradation in the corners by correcting for spot astigmatism
with internal neck magnets.
Exposure Control
ProPalette controls exposure as follows:
Exposure Parameter Control Method

DAC
Compensation for CRT
brightness drift (Autoluma)
12-bit ADC with 8-bit gain control, providing more

8K Series ProPalette Repair Manual Theory of Operation
Exposure System
Exposure Sequence
ProPalette uses the latent memory of photographic film to record light and to blend the
shapes and colors from a sequence of colored exposures. The exposures are made from
black-and-white, computer-generated video scan lines.
Upon command from the host computer, ProPalette creates a black-and-white video scan
line for a specified amount of time on the CRT. When projected onto film through lenses
and colored filters, a series of these scan lines creates a full-color image on the film. This
sequential exposure technique combines exposures of each primary color to produce
almost any shade or hue.
Exposure System Components
Figure 3-2 shows a simplified representation of the ProPalette exposure system. It
consists of a camera back/adapter assembly, a filter wheel assembly, a filter wheel photointerrupter that provides wheel position information, an autoluminance photodiode
assembly to sense CRT brightness, and the CRT assembly.
Figure 3-2. ProPalette exposure system
Camera Back/Adapter Assembly
Several camera back assemblies are available for use with various ProPalette models.
Each camera back includes a fixed-focus, fixed-aperture lens. (ProPalette controls
exposure via the intensity and duration of the CRT scan lines.)
Filter Wheel Assembly
The filter wheel assembly positions the appropriate colored filter (red, green or blue)
between the CRT and the film. Filter movement is initiated by the host computer, which
issues a command to ProPalette to rotate the filter wheel until the appropriate filter is in
position.
59
Page 60
8K Series ProPalette Repair Manual Theory of Operation
The filter wheel has four positions:
Position 1. Red filter (start position)
Position 2. Green filter.
Position 3. Blue filter.
Position 4. Opening without a filter, for viewing the CRT during testing and
calibration.
If a command from the host computer requires the filter wheel to turn to a higher filter
position, the filter wheel rotates directly to the specified position. If the instruction is to a
lower filter position, the microprocessor control circuit directs the filter wheel to rotate to
the start (1) position, and then to the requested position.
Filter Wheel Photo-Interrupter
On the rim of the filter wheel are notches that are detected by the filter wheel photointerrupter. The photo-interrupter contains a LED and a photo-transistor. When a notch
on the filter wheel passes between the LED and the photo-transistor, the photo-interrupter
generates a pulse that is detected by the microprocessor control circuit.
By counting the pulses from the photo-interrupter, the microprocessor on the ProPalette
digital board determines the position of the filter wheel and starts or stops the stepper
motor as necessary to position the filters correctly.
Filter Wheel Stepper Motor
The filter wheel stepper motor rotates the filter wheel assembly using a small rubber
roller on the motor shaft. Using information from the filter wheel photo-interrupter, the
microprocessor control circuit on the digital board increments the stepper motor as
needed to move the filter wheel to the proper position.
Autoluma Board
The autoluma board consists of a photo-diode and associated circuitry. It provides a
voltage output that is proportional to the light seen by the photo-diode.
Power Supply
AC Power
ProPalette operates with domestic or international commercial AC power applied through
the main power switch and the voltage selector.
Note: ProPalette meets domestic and international power
requirements. It operates from 100/115 to 220/240 volts at
50/60 Hz commercial AC power.
60
Page 61
8K Series ProPalette Repair Manual Theory of Operation
When the main power switch is on, AC power is applied to the low voltage power supply.
An LED on the front of the ProPalette unit indicates that the unit is powered.
DC Power
Regulated DC voltages are generated from the low voltage power supply. They are
applied to the analog board through connectors J31, J32 and J37, and to the digital board
through J4. These voltages power the following:
• Digital board
• Analog board
• High voltage power supply
• Filter wheel stepper motor
• Camera back via connector
• Small system computer interface (SCSI)
The DC power system is shown in Figure 3-3.

Flash Memory
512KB of Flash memory is used to store the firmware, film tables, CRT calibration data,
autoluma data, the frame count, SCSI bus ID and various other volatile data types. At
power-on, the film printer copies the firmware from Flash memory to DRAM and runs it.
The current Digital Board design employs a single 5V-only flash chip that sits on the V53
buffered data bus. The chip, an AM29F400T, is used exclusively in the byte mode. The
V53 address lines connect to the address inputs and the V53 memory read and memory
write outputs drive the flash output enable and write enable inputs. The RCTL1WT PAL
asserts a chip select signal, whenever the V53 addresses the upper 2Meg of its 16Meg
address space.
V53 Timer0 (Real Time Ticker)
The V53 has several internal timers including Timer0 which is used to generate a
periodic OS interrupt or clock tick.
Group 2 Functions
DSP and Communications with V53 and DSP SRAM
A diagnostic routine built into the firmware verifies the DSP is working, checks all of the
communications between the V53 and the DSP and tests the 2 8Kx8 DSP SRAMs.
When the DSP is in the 'hold' state, the V53 has direct access to the DSP SRAM and the
DSP I/O devices.
Group 3 Functions
Parallel Port, J19
Parallel port hardware consists of the ECP_PORT PAL (Lattice pLSI1016-60), one
74ACTQ646 8-bit bi-directional bus transceiver, one 74AC245 8-bidirectional buffer and
one 74ACTQ244 8-bit buffer.
SCSI Port, J14
SCSI port hardware consists of a XX53C94 SCSI controller I.C., a UC5601 active
terminator I.C. and a 20 pin resistor pack. The SCSI controller is connected to the V53
data bus, the V53 buffered data bus and four V53 address lines.

Filter Wheel Stepper Motor Control, J5 & J6
Two high-voltage, medium current dual peripheral drivers (75477) generate
PHASE1/PHASE2 and PHASE3/PHASE4 which turn on and off current in four stepper
motor windings. One side of each stepper motor winding is tied to +15Vdc and the other
side attaches to the low-side drivers (PHASEX). PHASE1 and PHASE 2 should always
be the complement of each other.
The same relationship applies to PHASE3 and PHASE4. Three 82C55 output bits control
the peripheral drivers. INTLED provides current for an LED photo-interrupter which
outputs a logic signal, FWSENSE, to indicate when a filter wheel slot is front of the
sensor.
Camera Back Interface Circuit, J13
The camera back interface is made up of one 74VHC244 8-bit buffer, one 74HC273 8-bit
latch, one 74HCT257 quad 2-to-1 mux, one LM311 comparator, two 75477 medium
current low-side drivers, one 2SA1314 PNP power transistor, one 754410 (or L293D)
dual half H-bridge and one LM317 linear voltage converter. The 8-bit buffer serves as an
input port for signals output from the camera back. DX code bits are selected for reading
via the 2-to-1 mux.
Both the 8-bit buffer and the 8-bit latch sit on the V53 buffered data bus, VBD7-0. The 8bit latch controls the camera shutter and film motor via control outputs fed to the 2 lowside drivers, the dual half H-bridge and an open-collector driver connected to the base of
the PNP power transistor. The remaining 8-bit latch bits serve as the select bit for the 2to-1 mux and the perforation sensor LED On/Off control. The comparator translates the
perforation signal from the camera to a valid logic level. The voltage converter steps
15Vdc down to 6.4Vdc to supply the half H-bridge output driver.
LCD/Keypad Module Interface, J12
This interface consists of one 8-bit 82C55 port for LCD module data bus lines, four more
82C55 outputs for LCD module and backlight control, four 82C55 inputs for reading
keypad keys, one 2SA1314 PNP power transistor for driving the LCD backlight and 1/2 a
74HC20 4-input NAND gate for generating a key interrupt to the V53.
Analog Board Data and Control I/O, J18
The Digital Board outputs a number of data and control signals which connect to devices
on the Analog Board.

Analog Board
The ProPalette analog board contains all the D/A and A/D converters required for full
digital control of the CRT deflection, luminance, video and focus. A single 64-pin ribbon
cable connects the analog board to the digital board. This cable carries a 16-bit bus (a
buffered version of the DSP data bus) and various control signals.

Slowscan Description and Imaging Sequence
This section provides a description of the ProPalette slow scan exposure process and the
activities that the TMS320C26 DSP performs during an exposure.
The DSP has direct control over five D/A converters to control the CRT:
• X deflection- DAC
• Y deflection- DAC
• Video- DAC
• Cos4- DAC
• Dynamic Focus - DAC
68
Page 69
8K Series ProPalette Repair Manual Theory of Operation
For a slow scan exposure, the three DACs for deflection and video are updated to scan
the beam. The Cos4 and Dynamic Focus DACs are updated at a slower rate.
The design goal is to be able to expose an image on 35mm film in less than 1 minute. The
exposure process includes some startup time where a brightness auto-calibration is
performed, and the exposure of three color planes; red, green, and blue. Between the
exposure of each color, the color wheel must be moved.
The time to expose a line includes the time required to sweep the crt beam horizontally,
displaying all of the pixels, and the time to retrace the crt beam to the beginning of the
next line.
The mix of activities performed by the DSP, and dedicated hardware have been chosen to
accommodate the major activities of:
• Generation of deflection values for the X and Y deflection DACs
• Generation of Cos4 and Dynamic Focus values
• Generation of video DAC values at the pixel rate.
Grid for Deflection
Digital grid point information representing horizontal, vertical, video, COS4 , and
dynamic focus data is sent to the DSP which operates on the information and controls the
output timing of this data to the analog board.
Video DAC Data Generation
Pixel data is provided from the host computer as either RGB data or in a RLE format.
RLE data is converted to raw RGB pixels. RGB data is a byte per pixel per primary color.
For each primary color, we have a byte value which indicates the density of that primary
color for each pixel.
This pixel data must be converted to video DAC data. This is a non-linear conversion
which must accommodate both the contrast of the CRT and the non-linearity of the film.
There is a non-linear one-to-one correspondence between the pixel value and the video
value. Throughout this documentation we make a distinction between pixel data and
video data. Pixel data is a byte value which represents the brightness of a pixel. Video
data is a 16 bit value to the video DAC to get that brightness on film.
Hardware is dedicated to do a pixel-to-video conversion at the required throughput rate.
The hardware is a 256 word memory which is loaded with a video lookup table. The
memory is addressed with the pixel value and the output is the video value. A DMA
channel is dedicated to sending the pixel data from it's memory to the lookup table and
the output of the lookup table is sent to the video DAC.
69
Page 70
8K Series ProPalette Repair Manual Theory of Operation
For each primary color, the V53 must load the video look-up table with pixel-to-video
values. This is a 256 word table. Before the exposure of a each line, the V53 initializes
it's video DMA channel with a pointer to the beginning of the pixel data in it's DRAM for
that line.
Exposure Summary
The V53 must have the following information available before an exposure begins:
• Grid point data for X and Y deflection
• Grid point data for Cos4 and DyFocus
• A DRAM memory pipe filled with pixel data for the current
primary color. While the exposure proceeds, the V53 must keep
up with generating pixel data for subsequent lines. If the
availability of pixel data starts to fall behind, then the exposure is
slowly and gracefully throttled down so that the exposure rate
matches the delivery rate of pixel data from the host.
There are two V53 DMA channels dedicated to supplying data to the DSP. One channel
provides grid point data and the other supplies pixel data.
Flash Description
The flash devices in ProPalette are programmable, non-volatile memories which are used,
primarily, to store the control code and gridpoint data for the ProPalette system. Other
programs and data can be placed in the system such as diagnostics and control
information.
Flash Data Organization
The flash contains data blocks of various sizes. Each data block is preceded by a flash
header. The header contains information on what is in the data block and how large the
data block is.
The flash header structure is defined:
flash_data_type It lists all of the valid data block types which can reside in
flash.
data_length Length of the data block (excluding the header) in bytes.
software_version Version of the program which put this data block into flash.
This is not necessarily the version of the data or program in the block.
70
Page 71
8K Series ProPalette Repair Manual Theory of Operation
startup_segment The segment address of where this data goes. For data blocks
which are raw data, as opposed to programs, this value is 0. For data blocks
which are programs, this is where the programmed is moved when it gets
executed.
hdr_name A description of the data block type.
data_name Description of the data itself and is provided by the program which
actually puts the program in flash. For an executable, this is typically the name of
the program. For instance, for the CNTRL_CODE flash_data_type, the
hdr_name is 'Control Code' and the data_name would be something like 'kacntrl'.
There is no fixed order of data blocks in flash. They are programmed into flash as they
are received. Data blocks cannot be duplicated; there's only one copy of a given data type
in flash at any time. If a data block is to be programmed and an older copy already exists,
then the older copy is effectively overwritten.
Programs for Reading and Writing the Flash
Two low level programs are available to read and write the flash. Other programs can
include code to manipulate the contents of flash. For instance, kacntrl can put GridPoint
data into flash. The format of the GridPoint data is out of the domain of the general flash
programs and this data is only programmed by kacntrl.
The two low level general purpose programs which are available are the Flash Dispatcher
and the Flash Manager.
The Flash Dispatcher resides in EPROM and is able to read a directory and start any of
the programs which reside in flash.
The Flash Manager is a program which may reside in flash and be can be started by the
Flash Dispatcher. It can add data blocks, remove data blocks, and erase the entire flash.
Normally, production units do not have Flash Manager burned in flash. If Flash Manager
is needed, it can be loaded and executed from DRAM. For more information about using
the Flash Manager, see page 153.
When the system is started from a hard reset, startup code examines the state of the
startup switches on J3. The two startup switches, J3-6 and J3-8 provide four states:
State J3-6 J3-8
ROM Monitor gnd gnd
Debugger open gnd
Control Code (default) open open
Expansion Code gnd open
The ROM Monitor is started, using the first serial port as a console.
71
Page 72
8K Series ProPalette Repair Manual Theory of Operation
The Debugger is started, using the second serial port for talking to the remote debugger
which is running on the host.
When the switches are set to Control Code or Expansion Code, the EPROM version of
the Flash Dispatcher gets control.
If the switches are set for Control Code, the Flash Dispatcher moves the CNTRL_CODE
data block to DRAM and starts executing the code.
If the switches are set for Expansion Code, the EXPANSION_SWITCH data type is read
from flash. The data block in the EXPANSION_SWITH data type contains two pieces of
data; a program to run and a flag indicating whether this program should be directly
executed or whether it should be run using the debugger.
Autoluma Process
The autoluma calibration process measures the light emitted by the CRT using a photo
detector. This is done by varying the luma control output (G1) and video output while
scanning the CRT. The clear window of the filter wheel is in front of the solar cell at this
time to maximize the light measured by the solar cell.
The autoluma calibration process creates a data curve of video DAC input level vs. CRT
brightness (from the darkest to the brightest amount of light needed to expose the film
type chosen for the image). This curve is used to create a lookup table that maps pixel
values to video DAC values.
If the calibration process cannot find a CRT light level dark enough for the film, (i.e.
there is always light recorded by the solar cell) an error of “CRT not dim enough” will be
reported by the film recorder.
If the calibration process cannot find a CRT light level bright enough for the film (this
could mean that no light is emitted by the CRT), an error of “CRT not bright enough”
will be reported by the film recorder.
If the measured curve is not monotonically increasing from darker to brighter values, the
errors “luma not smooth” or “video not smooth” will be reported by the film recorder.

Firmware Description
Downloading New Firmware
New firmware can be downloaded to the ProPalette for storage in flash. The new copy
replaces the copy in the unit.
General Description
New firmware is sent to the Propalette in the Intel HEX format from the host computer.
After all of the hex data is transmitted, the firmware is burnt into the Flash. This process
takes about 40 seconds and the progress is displayed on the LCD. After the new firmware
is in flash, the ProPalette is restarted so that the new firmware is running.
Camera Back Interface
The ProPalette has a flexible camera back interface including a 400 mA shutter driver, an
X-connector input (for shutter control), a film door switch input, a film perforation sensor
input, a 500 mA bi-directional film motor driver, 6 DX code inputs for sensing ISO film
speed, +5V @ 2A and +24V @ 1.2A power outputs.
Camera backs connect to the ProPalette through a 20-pin edge connector suitable for a
double sided, 0.049" thick PC board with 10 signal conductors per side. The PC board
traces must be 0.040" +/- 0.005" wide on 0.100" +/- 0.005" centers.
The connector pinout is described in Figure 3-7 and Table 3-3. All 'inputs' are inputs
from the film recorder's perspective (outputs from the camera back). Control signal
timing may be individually adapted to the various camera back types when their interface
requirements are defined.

The ANSI specification for 135-Size Film Magazines and Film (35mm) identifies 25
five-bit DX codes for sensing ISO film speed. Thirty-two total combinations are possible
with five bits, leaving seven combinations unused. Polaroid uses these 'open' DX code
sequences to identify various camera back types for use with ProPalette. Detection of any
valid DX code, or no DX code, indicates a 35mm camera is attached. Other camera types
are identified in Table 3-4.

Keypad/LCD Interface
The ProPalette film printer features a 2 line x 20 character backlit LCD and
accompanying 4 key input panel. Each character is composed of a 5x7 matrix of pixels.
The display supports direct printing of ASCII strings via an internal character generator.
New characters, ie. not part of ASCII set, may be displayed by overwriting the default
character codes in the display RAM. Any combination of 5x7 pixels may be defined.
A 4 key input panel sits directly underneath the LCD. The keys are labeled, left to right,
UP - DN - SEL - ESC. Various film printer set up functions are accessible through the
keypad. These functions are divided into 6 categories (menus); setup menus are displayed
for 5 seconds after the ESC button is pressed.

Film Tables
Film type selection via the keypad provides access to any Flash resident film tables. If a
film is selected via the keypad, it overrides any attempted film table downloads from the
host. If the host attempts to download a different film table, a "Film wrong for camera"
error is generated.
Pacing Commands
During the exposure of an image, the CRT beam must move in a smooth and consistent
manner. If the ProPalette can print faster than pixel data is being received, there will be
pauses in the exposure while the printer waits for additional data. An artifact appears on
the film as a result; appearing as a horizontal line.
A slow host computer may force the ProPalette to wait for data during a line scan. This
will result in a regular pattern of dark lines within the image. To eliminate this problem,
Pacing should be enabled on the LCD panel. This will insert a user defined wait between
scan lines, allowing the host computer to process the necessary image data. The amount
of pacing should be increased in small steps until the data wait lines have been
eliminated. An excessive pacing time will increase the total exposure time of the entire
image.
The host program or keypad can set the pacing to extend the total line time.

4 Troubleshooting and Diagnostics
Recommended Diagnostic Sequence
Several methods can be used for performing diagnostics on the 8K series ProPalette
models. An initial self test is performed when the unit is first turned on, the reset button is
pressed or “Run Startup Diagnostics” is selected from the LCD/keypad. A complete set
of diagnostics, in addition to system alignment, can be performed via the system test
stand. (Refer to ProPalette Test Stand Manual for more information).
Utility Program Summary
Board-level tests and system utilities can be run if the correct software is available and
installed on a host computer. However, the board level tests are not necessary because the
same functions are performed by either the start up diagnostics or the system test stand.

Page 81
8K Series ProPalette Repair Manual Troubleshooting and Diagnostics
Upgrade Procedure with Parallel Cable
Use the procedure in this section to upgrade the firmware of a ProPalette film recorder
that displays normal LCD panel messages after startup. If the ProPalette unit does not
have functioning firmware and displays only a blinking cursor on startup, you must use
the Flash Manager utility to reload the firmware instead. (Refer to page 155 for detailed
instructions.)
Note: The following procedure cannot be performed with the
Windows NT operating system.
1. Connect a parallel cable between the PC (LPT of your choosing) and the film
recorder.
2. Power on the film printer and wait for the “Ready” message to appear on the
LCD.
3. From the sub-directory that contains the extracted files, run FWLOAD.EXE
<hexfilename> <portnum> where hexfilename is the path and name of the
control code hexfile, eg. KACNTRL.HEX and portnum is the LPT port
number connected to the printer. The default parallel port is LPT1; if the
printer is connected to LPT1, there is no need to specify portnum. If no
hexfilename is specified, FWLOAD attempts to load 'KACNTRL.HEX' from
the current directory.
4. Wait until the program reports it has finished and the film printer resets itself.
(The LCD displays "Getting data...", "Programming flash..." and "Resetting..."
during the download/burn process.)
Caution: Do not shut down the ProPalette or the PC until the
ProPalette has performed an automatic reset.
The new firmware version appears on the LCD panel, indicating that the
upgrade has been successful.
Upgrade Procedure with SCSI Cable
To upgrade the firmware of a ProPalette film recorder through the SCSI interface, follow
the instructions below.
Please note the following before you start:
• Each film recorder model (ProPalette 8000, ProPalette 7000 or ProPalette 8K Series)
has a separate upgrade utility.
• You can upgrade only one film recorder at a time.
81
Page 82
8K Series ProPalette Repair Manual Troubleshooting and Diagnostics
• For upgrading more than one film recorder of the same model when all are connected
to the SCSI bus, turn the power off to all but one of the units and perform the upgrade
to the unit that still has power. After the upgrade is complete, power off the upgraded
unit and power on another unit to be upgraded. Perform the upgrade again to any
remaining film recorders of the same model number. Repeat this process until all film
recorders of the same model have been upgraded.
• The upgrade utility intelligently detects all the film recorders connected and will
upgrade only the appropriate model connected and only if its firmware is older than
one incorporated in the upgrade utility.
• To find out what firmware version is incorporated in the upgrade utility, click on the
About menu option after you start the utility.
• To start the upgrade process, select the Start option from the Program menu.
• Do not interrupt the upgrade process once it has begun. Interrupting the power to the
film recorder or pressing any buttons on the control panel before the upgrade has
completed can cause the film recorder to require service.
• You cannot upgrade the ProPalette 8000 or ProPalette 7000 using this utility if the
current firmware version is correspondingly 564 or 704 or if the film recorder is
connected to the computer with a parallel connection. Please use the DOS utility
FWLOAD and a parallel connection to upgrade any film recorder that contains
firmware versions 704 or 564.
To upgrade the film recorder firmware, use these steps:
1. Select and download appropriate upgrade utility for the model film recorder.
2. Make sure that the film recorder is properly connected via SCSI, powered on
and terminated.
3. Run the appropriate utility for the film recorder you want to upgrade;
4. Start the upgrade process by clicking on the Start option of the Program menu.
5. Monitor the upgrade process, which normally requires 3-4 minutes. For some
SCSI cards and older systems, the upgrade process may take longer but should
not exceed 12-15 minutes.
6. Before attempting to use the film recorder, wait until the firmware is
completely downloaded and the unit restarts and reads "Ready" on the LCD
panel.
Warning: Failure to wait for the upgrade process to complete
may erase the film recorder flash memory and require
the unit to be serviced.

ProPalette Startup Diagnostics and Tests
ProPalette automatically runs the following diagnostics when it is powered up, reset or
when Run Startup Diagnostics is selected from the ProPalette LCD menus:
Filter wheel stepper motor driver. Tests filter wheel stepper motor
driver on digital board by moving the filter wheel to home position,
then indexing it.
DRAM test. Tests heap and expanded memory. Tests all expanded
memory or a 2-meg block of expanded memory. Returns the amount of
expanded memory found.
SRAM test. Tests the DSP SRAM.
Horizontal channel. Checks for correct horizontal channel output
when horizontal DAC16 input, horizontal size trimdac and horizontal
center input on the analog board are individually exercised. Refer to
Figure 4-1.
Vertical channel. Checks for correct vertical channel output when
vertical DAC16 input, vertical size trimdac and vertical center input on
the analog board are individually exercised. Refer to Figure 4-1.
Video channel. Checks for correct video channel output when the
video DAC16 input and Cos4 DAC on the analog board are exercised.
Refer to Figure 4-1.
Luma trimdac. Checks for correct output from each of the two analog
board luma trimdacs (hi_luma and lo_luma) when they are
individually exercised with the other luma trimdac zeroed. Refer to
Figure 4-1 on page 84.
Dynamic focus. Checks for correct dynamic focus DAC output on the
analog board when the DAC is exercised. Refer to Figure 4-1 on page
84..
Note: The analog board tests above (horizontal channel through
dynamic focus) are static tests only and may not detect
analog board problems that occur only under dynamic
conditions. If this test is successful and you still suspect
that the analog board is faulty, replace the analog board.
Any problems detected by these diagnostics are reported on the ProPalette LCD display
during the tests. (The most recent error can be redisplayed by selecting Show Last Error
from the ProPalette LCD menus.)
Note: On firmware version 564 and later, the Startup Diagnostics
must fail on three attempts before it is reported as a system
error. These software programs will incorrectly indicate a
failure for a single intermittent occurrence of an error.

Test Image Exposure Sequence
To verify system operation, ProPalette cycles through the sequence for printing a test
pattern when Test Image is selected from the LCD menus.
By removing the camera and looking through the camera mount, a technician or operator
can verify operation of the CRT (a grid appears on the CRT face) and the filter wheel
(normal rotation sequence).
If a loaded 35mm camera is attached to the ProPalette when the self test is initiated, the
shutter opens just prior to the RED exposure and closes at the end of the BLUE exposure.
There is no change to any frame count and the film must be moved via the keypad
controls. This allows camera functionality to be verified.
Monitor Mode
The monitor mode selection on the ProPalette LCD menus passes control of ProPalette to
its EEPROM. This item is intended only for low-level tests during manufacturing and
service and has no use in normal operation.
If monitor mode is accidentally selected, press the Reset button on the rear of the
ProPalette to restart the system and return to normal mode. For more information about
entering Monitor mode, see page 51.
Error Message Redisplay
Error messages produced by startup diagnostics are displayed on the ProPalette LCD
panel for a few seconds. To redisplay the most recent error, select Show Last Error from
the ProPalette LCD menus.
Errors are also stored in flash memory and can be viewed with a host-side utility. See
