1 INTRODUCTION
What is redCAM?
A small but complete vision system. The vision sensor redCAM closes the gap bet-
ween photo electric sensors and image processing. By integrating camera and image
processing hardware redCAM can be used as a sensor, offering the efficiency of indu-
strial image processing. The redCAM is appropriate where a simple photo electric
sensor is not sufficient and a high performance system is oversized.
With a size hardly exceeding the dimension of a standard CCD camera redCAM can
easily be integrated everywhere into production. Standarized industrial interfaces and a
protocol meeting industrial requirements makes integration of redCAM into a produc-
tion plant easy.
The redCAM is being adapted by an external PC or notebook used as a programming
device to the needs of production. For this purpose you have in hand a comfortable
and easy-to-use Windows program. Using this program and the operating manual the
system can be parameterized without having knowledge of programming and image
processing. After disconnection the camera operates self-contained.
During the development of the high-performance image processing software for
redCAM Leuze electronic could go back to a yearlong experience in industrial image
processing with high-performance systems. The functions of pattern recognition, gray
scale value analysis, and edge detection can solve a wide range of operating and con-
trolling tasks where photo electric and simple sensors are not exact and flexible
enough.
Short description of the system
The package consists of one redCAM vision sensor and the specific Windows para-
meterizing program. The redCAM is pre-configured for the operation of one of the fol-
lowing tools:
Measurement: A tool for automatic optical measuring of components in pro-
duction.
Completeness: A tool for automatic optical test of existance, features and posi-
tion of components in production.
Reader: A tool for automatic optical identification of components by me-
ans of fonts and optional further features.
Barcode: A tool to read barcodes under harder conditions.
DataMatrix Reader: A tool to read DataMatrix Codes.
In addition you need a PC with the operating system Windows95, Windows98 or
WindowsNT for the operation of the program and a monochrome screen (camera-type
ViS 5, ViS 7) or a VGA-screen (camera-type ViS 7V; ViS 6P, ViS 8P or higher) to
display the image recorded by the sensor and the faded-in measuring devices.

By help of the serial interface and four separately opto-decoupled parallel in- and out-
puts the vision sensor can be directly connected to the control system. Running in au-
tomatic mode redCAM is a self-contained sensor executing and loading data and pro-
grams stored in EEPROM. This guarantees instant readiness after the switch-on of the
operating voltage and 100%-control of produced components at high clock frequen-
cies.
How to use this Operating Manual
This Operating Manual first describes basic concepts and processes. Then you will be
guided throught the functions step by step. The use of the functions by means of me-
nus or through the buttons of the control bar are described in detail. With the help of
sketches and numberings the proceeding is comprehensibly explained.

2 INSTALLATION
The installation program guides you through the installation. The program copies the
files to an existing folder on your hard disk, alternatively the folder might be newly
created. In addition to that an entry for the Windows95 start menu is created. We re-
commend to create a link to the program on your desktop in order to accelerate the
start of the parameterizing software. For Barcode and DataMatrix Reader there is no
parameterizing program available currently.
System requirements
- Hardware and software requirements:
·Windows95, Windows98 or WindowsNT
·486 or Pentium based system
·Mouse or track ball
·VGA graphics adapter
·Minimum 16MB RAM for Windows 95 (more for higher Windows versions)
·Approx. 5MB available hard disk space for installation of the files
·A free serial interface on the PC
An additional monochrome screen (or RGB screen) for the video display of the vision
sensor. A VGA screen is not suitable for video display.
- Back-up copies
The software is provided on CD-ROM. You should make a back-up copy of the original
CD-ROM, in order to be able to continue your work in case the original CD-ROM gets
damaged. Use the back-up copy for installation and keep the original CD-ROM in a
safe place.
- Installation
The files are compressed. Thus, you cannot copy the files manually to your hard disk.
An installation program facilitates the installation procedure.
This program is started from the CD-ROM drive of your PC. For most systems the
drive name is D:. The following installation instructions refer to D: as the drive name of
your CD-ROM drive.
How to install on your PC:
·Insert the CD-ROM containing the programs Completeness, Measurement, Reader
or Barcode into the CD-ROM drive of your PC
·Select the start button on the windows task bar and then Run. Insert source drive,
path and then SETUP into the dialog box.
·D:\SETUP.EXE
·Follow the instructions given in the various dialog boxes of the installation program
and store the program in a folder of your own choice. After completion of the in-
stallation you can start the program like every other program under Windows.

Removal of the program
You can remove the parameterizing program and the required additional files from
your PC. To remove the parameterizing program from your PC:
·Select the Start button in the Windows task bar and then Settings. From the pop-
up menu select Control Panel.
·In the Control Panel window double-click on Add/Remove Programs. You will find
the parameterizing program in the list of installed programs.
·Select it and klick on the button Remove. Follow the instructions given in the va-
rious dialog boxes of the deinstallation program.

3 RUNNING THE PROGRAM
After having installed the program you can start it now. How to start the program:
·Select the Start button in the Windows task bar and then Programs.
·In the pop-up folder menu select the entry for the parameterizing program and klick
on the program icon.
After starting, the parameterizing program appears in a window which you can zoom to
screen-size using the usual Windows buttons.
3.1 USER INTERFACE
The program user interface appears in the usual layout of a Windows operating sy-
stem. You will find a primary window which you can zoom to screen-size using the title
bar buttons. Using further buttons you can reduce the window to a symbol or you can
close it completely. In the right and the bottom margin there are scroll-bars. To change
the window's size, klick and drag on the lower right corner of the window.
Example: User interface of the Detection-parameterizing program
The window consists of:
·Title bar
·Menue bar
·Tool bar
·Communication area

The communication area consists of:
·Buffer status indicator
·Command text fields
·Counter with buttons
·Title bar
The title bar is at the top of the window:
- Title bar
On the left side of the title bar there is the program icon. Next to it you will find the na-
me of the current document being processed. To the right there is the title text of the
program; in the right sight you will find the window buttons.
- Menue bar
Below the title bar there is the menue bar with the menue entries:
- Menue bar with short-cuts
You can select the menue titles either with the pointer element (mouse) or the key-
board short-cuts. These short-cuts are underlined.
- Tool bar
You can start actions of the program with the tool bar below the menue bar, here the
tool bar of the Completeness program is shown:
Example: Completeness program tool bar with quick info
The meaning of the icons can easily be understood from their graphics. When you
point with the mouse to an icon without clicking, a quick-info box will appear after a
short time showing a short description of the icon.
At start-up, the buttons of the tool bar appear grey to indicate they are not available.
Only the buttons to connect and configure the interface are available and therefore
coloured. Since the connection to the vision sensor has not been completed yet,
