How to Use this Instruction Manual
Electricity Warning
Assembly and initial operation of the line scan camera must be carried out
under dry conditions.
Do not operate the camera if you notice any condensation or moisture in
order to avoid danger of a short circuit or static discharge!
Risk of High Power Lighting
According to the application, laser or high power LED light sources might be
used. These can affect your eyesight temporarily or even cause permanent da-
mage to the eyes or skin.
Do not look directly into the light beam!
Mechanical Warning
Ensure that the scanner axis is free to move and that no obstacles are in the way
– especially fingers!
Do not place any body parts in the way of moving parts!
For typical use in a scanning application, please consider the following
warnings:

1 Introduction
SK6288U3KOC Instruction Manual (02.2016) © 2016 Schäfter + Kirchhoff GmbH • Hamburg
The SK line scan camera series is designed for a wide
range of vision and inspection applications in industrial
and scientific environments. The SK6288U3KOC is highly
portableandtherobustlyattached dedicated connections
enable external synchronization of the camera and the
output of data to the USB 3.0 port of the computer.
The USB 3.0 connection supplies power to the camera
and the camera is hot-pluggable, providing the greatest
degree of flexibility and mobility. The computer does not
require a grabber board, allowing a laptop to be used
when space or weight restrictions are also at a premium.
Once the camera driver and the SkLineScan®program
have been loaded from the SK91USB3-WIN CD then the
camera can be parameterized. The parameters, such as
integration time, synchronization mode or shading
correction, are permanently stored in the camera even
after a power-down or disconnection from the PC.
The oscilloscope display in the SkLineScan®program
can be used to adjust the focus and aperture settings, for
evaluating field-flattening of the lens and for orientation
of the illumination and the sensor, see 3.1 Software:
SkLineScan, p. 10.

frequency limitation. This will reduce the data transfer rate as well as the power consumption to the USB 2.0
specifications.

2 Installation and Setup
2.1 Mechanical Installation: Mounting Options and Dimensions
Casing type AT2
Mounting Options
• The best fixing point of the camera is the collar for
the mounting bracket SK5105 (available as an
accessory).
• Four threaded holes M3x 6.5 mm provide further
options for customized brackets.
• The length and weight of the optics might be beyond
the capability of the standard mounting bracket
SK5105. For this purpose, a second mounting
bracket type SK5105-2 to hold the tube extension
ring(s) is more appropriate.
Optics Handling
• If the camera and the optics are ordered as a kit,
the components are pre-assembled and shipped
as one unit. Keep the protective cap on the lens
until the mechanical installation is finished.
• If you must expose the sensor or lens surface,
ensure the environment is as dust-free as possible.
• Gently blow off loose particles using clean
compressed air.
• The sensor and lens surfaces can be cleaned with
a soft tissue moistened with water or a water-based
glass cleaner.

2.2 Electrical Installation: Connections and I/O Signals
All Schäfter + Kirchhoff USB 3.0 line scan cameras can be operated with a USB 2.0 interface. Note that there might
be limitations in terms of the maximum data transfer rate and the power supply. The details for your camera can be
found in section 1.4 Line Scan Camera - Specifications, p. 5.
2 Installation and Setup
Accessories (see also Accessories and Spare Parts, p. 32):
• TheUSB 3.0 interfaceprovides datatransfer,camera controland powersupply capabilitiesto theSK6288U3KOC
line scan camera. If you want to operate the camera in Free Run (SK Mode 0) trigger mode the USB3.0 cable
is the only connection you have to make.
• For any kind of synchronized operation, the external trigger signal(s) must be wired to socket 2. A frame-
synchronization signal and two separate line-synchronization signals can be handled. The various trigger
modes are described fully in section Synchronization of the Imaging Procedure and the Object Scan Velocity,

2.3 USB3 Connections and SkLineScan Software Installation
2 Installation and Setup
This section is a quick reference for installing the SkLineScan adjustment and configuration software and to set
up the USB3 camera driver. SkLineScan and the SkLineScan manual is provided for download on the
Schäfter + Kirchhoff website under http://www.sukhamburg.com/support.html. It is also part of the fee-based
software development kit SK91USB3-WIN.
SkLineScan Installation and Automatic Camera Driver Installation
Prior to the installation, power on the PC (not the camera) and unpack the downloaded zip-file to a temporary
folder. Alternatively, if your installation medium is a CD, insert the disk to the drive.
The autostart function may launch the setup program automatically from CD. Otherwise, look for one of these
installation files:
SkLineScan-USB3-Win_x64.msi SK91USB3-Win_x64.msi
SkLineScan-USB3-Win_x86.msi SK91USB3-Win_x86.msi
Then start the applicable installation file manually. This will set up the Schäfter + Kirchhoff SkLineScan camera
control and adjustment tool as well as the USB3 Line Scan Camera Driver.
Step 1: Install SkLineScan. The setup program will
automatically install the Schaefter +
Kirchhoff USB3 Line Scan Camera Driver.
Step 2: Plug in the USB3 connection cable to the
camera. if appropriate switch on the external
power supply.
Step 3: Start the SkLineScan program.
Initial Function Test
• Quit the SkLineScan startup dialog
box.
• Select "OK" in the SkLineScan
start-up dialog.
The Signal Window showing the current
brightness versus the pixel number
indicates the correct installation.
Camera Setup
Use the Setup dialog for
• activating/deactivating a connected USB3 camera
(activated device is ticked)
• changing the pixel frequency
• setting the bit depth of the video signal to 8 or 12-bit.
In USB 2.0 mode the lower pixel frequency and 8-bit video
signal is recommended SkLineScan Setup dialog
SkLineScan Start-up
• Start SkLineScan.
• A start-up dialog box pops up and
displays the connected camera(s) that
have been automatically detected. It
also indicates the active USB standard. The optimum
performance is provided by USB3.0.
• The camera LED changes from red to green color light.

SK6288U3KOC Instruction Manual (02.2016) © 2016 Schäfter + Kirchhoff GmbH • Hamburg
3 Camera Control and Performing a Scan
Function Overview: SkLineScan Toolbar
New line scan. All open "Signal window" windows will be closed. [F2]
"Camera Control" dialog for parameter settings: integration time, line frequency, synchronization mode,
thresholding
Zooming in and out
New line scan. "Area Scan" windows will be closed, "Signal window" windows will remain open. [F2]
Threshold mode in new binary signal window.
"Shading Correction" dialog to adjust the white balance [Alt + s]
"Gain/Offset Control" dialog, also for commands input [Shif+F4]
New area scan
For an in-depth guide on how to perform imaging and to use the obtained data using the Schäfter + Kirchhoff
software package, see the SkLineScan Software Manual.
The most common functions of the line scan camera can be controlled by menu items and dialog boxes.
Commands controlling comprehensive camera functionality can be entered in the "Camera Gain / Offset
Control" dialog.
Click on the desktop icon to start the SkLineScan
program.
The SkLineScan program recognizes the connected line
scan cameras automatically. The identified cameras are
shown in the start-up dialog A, and the index order
corresponds with the individual MAC addresses of the
cameras.
If the SK6288U3KOC camera is identified correctly,
confirm with "OK". The "Signal window" graphicaly
showing the intensity signals of the sensor pixels (oscil-
loscope display) will open. It is responsive in real-time
and the zoom function can be used to highlight an area
of interest. The oscilloscope display is ideally suited for
parameterizing the camera, for evaluating object
illumination, for focussing the image or for aligning the
line scan camera correctly.
3.1 Software: SkLineScan
This section is a brief introduction to the SkLineScan adjustment and configuration software. A more detailed
description is provided in the separate SkLineScan manual. The pdf is included in the SkLineScan installation
package or is available for download from the Schäfter + Kirchhoff website under http://www.sukhamburg.com/
