1. PDC-2000 Description
General Description
The PolaroidDigital Camera, Model PDC-2000 (Figure 1-1), captures high-quality color
pictures electronically. It has all the features of an automatic compact 35mm camera, including
automatic exposure, electronic flash and automatic focus. These features produce correct
exposure, accurate colors and sharp focus under a great variety of picture-taking conditions.
Manual overrides are also provided for unusual conditions.
With appropriate image-processing software (such as Polaroid PicturePro or Adobe
Photoshop) and the Polaroid PDC-2000 plug-in software on a Macintosh computer or PC,
users can view the pictures taken with the PDC-2000 camera and transfer them to their
computer via a standard SCSI-2 interface. They can then use image-processing software to
manipulate, enhance, save and print the pictures.
When the camera is connected to a computer, the camera can be controlled and operated via
the computer keyboard and mouse. This is useful when the camera is used in a stationary
setup.
Figure 1-1. Polaroid digital camera, model PDC-2000
Models
The PDC-2000 is available in three different models:
Model Internal Storage Capacity (Megabytes)
PDC-2000/40 40 (40 images)
PDC-2000/60 60 (60 images)
PDC-2000/T None; tethered operation only
Front Rear

PDC 2000/3000 Repair Manual Description

Tethered operation refers to operation of the camera while it is connected to a computer. The
PDC-2000/T has no internal storage and must be connected to a computer to be operable.
Instead of storing images internally, it immediately transfers them to the computer as they are
captured.
Features
The PDC-2000 is designed for completely automatic, point-and-shoot operation. It
automatically sets exposure, focus and flash mode based on ambient light and distance to the
subject. Manual overrides are available for setting focus to infinity, setting flash mode to on or
off, and setting white balance to daylight, incandescent or fluorescent. A backlight-
compensation setting is also available.
The camera is capable of transferring its images to the computer in either of two resolutions:
(1) standard (800x600 dpi) and high (1600x1200 dpi). Both resolution modes are 24-bit color.
Because the camera always stores enough raw image data to produce the high resolution
images, resolution is not selected until pictures are being transferred to the computer.
Power for the camera is provided by four AA rechargeable NiCad batteries. These batteries
can be charged in the camera, using the battery charger provided with the camera. The
camera is operable while the batteries are charging.
An LCD panel on the camera provides information about time and date, camera status,
remaining battery capacity and error conditions. Time and date are recorded in the header of
each picture file, and on-camera controls allow the user to attach an additional alphanumeric
label to each picture file header. Time, date, label, and camera status transfer with the image
to the computer to aid identification and troubleshooting.

3. PDC-2000 Testing and Adjustment
LabView
Overview
LabView is a graphical application program designed by National Instrument. It is used to
graphically program instrumentation systems for data acquisition and control, data analysis,
and data presentation. This application program offers an innovative method in which a
design engineer can graphically assemble software modules called virtual instruments (VI's)
instead of writing text-based programs. VI's can be used to acquire data from plug-in boards
and programmable instruments such as PDC 2000/3000 digital cameras. VI's can also be
assembled to analyze data and to present results through graphical user interfaces.
A LabView virtual instrument (VI) consists of:
•Front Panel
•Block Diagram
•Icon/Connector
The following paragraphs only gives an overview of the LabView components necessary to
design a test program. Refer to the LabView User's Guide for more detailed information
pertaining to the LabView components necessary to design a test program.
Front Panel
The front panel is the user interface. It serves as an interactive interface for supplying
inputs to and observing outputs from the instrumentation system. LabView makes
creating a front panel as simple as drawing a picture and gives the user a variety of
controls and indicators to use.
When the VI is completed, the user uses it to control his/her system - even while the VI is
running - by clicking a switch, moving a slide, tweaking a knob, or entering a value from
thekeyboard, the front panel responds immediately, providing real-time feedback from the
instrumentation system.
Once the necessary information is entered or selected from the applicable front panel, the
user then starts the VI by clicking on the Start button. It then performs the test and
displays its results in the Test Status window on the front panel. Refer to the applicable
Testing and Adjustment section for a detailed explanation of the PDC 2000/3000 front
panel.

16
PDC 2000/3000 Repair Manual Testing&Adjustment
Block Diagram
The block diagram is the source code of the VI. It is constructed, free from syntactical
details of conventional programming, by selecting functional blocks from LabView menus.
The selected functional blocks are then connected with lines called wires to pass data from
one block to the next. These blocks include arithmetic functions, advanced acquisition and
analysis VI's, Sub VI components which call other VI's, and network and file I/O functions
that store or retrieve data in ASCII, binary, or spreadsheet formats.
Icon/Connector
The icon/connector is the calling interface. The icon is the graphical ID of the VI, and the
connector assigns controls and indicators to VI input and output terminals.
Test Software
The Test Software is an application program that was developed using LabView software
(National Instrument) and Concept VI Image Processing Library (Graftek). It is intended to
help the repair person diagnose PDC 2000/3000 digital camera malfunctions. Programs
developed using LabView are called virtual instruments (VI's).
The developed software consists of a Tester which invokes the necessary sub-VI's routines
that allow the repair person to check the PDC 2000/3000 digital camera.
When the Tester is invoked, it performs and verifies specified camera tests.
At the completion of the specified test, a report file is generated by the Tester indicating
whether or not the tested functions passed ( Pass ) or failed ( Fail ). It also list the current
parameters for the test functions so that repair person can verify the tested functions with the
PDC 2000/3000 digital camera specifications.
If the report file indicates that all or a particular function failed ( Fail ), the repair person can
compare the current parameters with the PDC 2000/3000 digital camera specifications to
determine how to bring the failed function/functions back into specification.

PDC 2000/3000 Repair Manual Testing&Adjustment
Tester Operation
Starting the Tester
1. If applicable, click the mouse on the front panel white arrow to start the tester.
2. Click the mouse on the Start button to start the test sequence.
3. Tester prompts the user to perform specified function when testing the PDC 2000/3000
digital camera.
4. Once all user prompts are completed, the test sequence for the PDC 2000/3000 digital
camera begins.
5. Upon completion of all or partial tests, a test completed message appears in the Status box
of the test panel.
Also, a test report and the Pass /Fail indicators displayed on the test panel are updated.
Stopping the Tester
Note: The Tester should not be stopped in the middle of a test sequence. However, if an
emergency situation occurs, use the following steps to stop and restart the Tester.
1. Click the mouse on the stop box to completely stop the camera's test sequence.
The black arrow changes to a white arrow indicating that the run-time version of LabView
stopped running.
2. To restart the Tester, just click the mouse on the white arrow; the arrow becomes black
again and the tester resumes.
Quitting the Tester
To quit the Tester due to a malfunction or before the selected tests are completed, just
click the mouse on the Closing box.
