Introduction
The camera must be mounted thermally coupled
so that the acceptable casing temperature is not
exceeded during operation. Therefore applies to the
thermal resistance of the bracket or heat sink:
θamb - θcasing
RthHS ≤
Pcamera
where
RthHS [K/W] = thermal resistance of the bracket or heat
sink
θamb [°C] = ambient temperature
θcasing [°C] = temperature of the camera casing (not
to be confused with the internal camera
temperature that is queried and output
with the request command I32)
Pcamera [W] = camera power consumption
• Intel Pentium Dual Core or AMD equivalent
• RAM min. 4 GB, depending on size of acquired
images
• High-performance video card, PCIe bus
• Operating Systems:
Windows 7 / 8.1 / 10 (64 or 32-bit) or
Linux kernel 3.13 or higher
Network Adapter:
• Any Gigabit Ethernet network adapter as a card
or on the motherboard is suitable. For the best
performance, a network interface card (NIC) with
Intel PRO/1000 chip is recommended.
• Network adapters that support Jumbo Frames
outperform adapters with fixed packet-size frames.

2 Installation and Setup
2.1 Mechanical Installation: Dimensions, Mounting Options, and Heat Dissipation
Casing type RG2
Mounting Options
When mounting the camera, pay attention to the
following:
• Mechanical stability to avoid vibrations.
• Good thermal coupling for cooling the housing.
The power consumption and the maximum
housing temperature of the camera are specified
in section 1.4 - Specifications.
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.

2.3 GigE Connections and Software Installation
GigE Network Integration for Standard GigE Network Adapters
The SK2048MVSH GigE VisionTM line scan camera uses the Gigabit Ethernet communication protocol, which is
100% compliant with the GigE VisionTM specifications and the Gen<I>CamTM standard.
The Gen<I>CamTM standard provides a generic programming interface for all kinds of cameras and, no matter what
features they implement, the application programming interface (API) always remains the same.
For software and Network Interface Controller (NIC) driver installation, the following possibilities apply:
1. The Gen<I>CamTM compliant 3rd party software you want to install includes a particular filter driver for
the NIC.
Install the software package. Commonly this will also cover the driver installation.
2. The 3rd party software does not include a NIC filter driver, and your NIC has an INTEL PRO/100 chip.
Install the Pleora eBUS Optimal Driver.
3. The 3rd party software does not include a NIC filter driver, and your NIC has a different chip.
Keep the manufacturer driver and follow the instructions in the next section.
The Pleora eBUS driver installation tool is available from Schäfter + Kirchhoff either on CD or as download from
http://www.sukhamburg.com/supporte.html
a) Subnet Setting
The GigE Vision camera has an enforced static IP
address. The NIC IP address must be part of the same
subnet otherwise the camera is not accessible.
An example of a persistent IP address that is assigned
to a class B network is:
Persistent IP = 169.254.35.10
Subnet Mask = 255.255.0.0
Default Gateway = 0.0.0.0
This section is relevant for systems with a standard NIC (not INTEL PRO /1000) in combination with the
manufacturer driver (case 3).

3 Synchronization of the Image Acquisition with the Feed Rate of the Object
A line scan camera produces a two-dimensional image by moving either the object or the camera. The direction of
the translation movement must be orthogonal to the sensor axis of the line scan camera.
In order to obtain an image with the correct aspect ratio, a line synchronous feed is required. With RGB color
sensors, the color sequence of the individual sensor lines must also be taken into account when processing
the sensor data. The software development kits from Schäfter+Kirchhoff contain easy-to-use functions for this
purpose.
If the object speed is variable or the accuracy requirements are high, external synchronization is required. The
various synchronization modes are described in the next section.
The optimal scan speed for a given line frequency is
calculated as follows:
WP·fL
VO=
ß
If the scanning speed is fixed, the line frequency must
be adjusted accordingly in order to obtain the correct
aspect ratio in the image:
VO·ß
fL=
WP
VO= object scan velocity
WP= pixel width
fL= line frequency
S= sensor length
FOV = field of view
ß= magnification factor
= S / FOV
Example 1:
Calculating the scan velocity for a given field of view and a given line frequency:
Pixel width = 14 µm
Line frequency = 14.10 kHz
S= 28.7 mm
FOV = 50 mm
14 µm · 14.10 kHz
VO=
(28.7 mm / 50 mm)
= 344 mm/s
Example 2:
Calculating the line frequency for a given field of view and object scan velocity:
Pixel width = 14 µm
Scan velocity = 300 mm/s
S= 28.7 mm
FOV = 50 mm
300 mm/s · (28.7 mm / 50 mm)
fL=
14 µm
= 12.3 kHz

Instruction Manual SK2048MVSH © 2021-04 E
Synchronization Modes
The synchronization mode determines the exact timing of the exposure. Synchronization can either be
performed internally or triggered by an external source, e.g. an encoder signal.
There are two different synchronization functions that can be applied together or individually:
1. Line synchronization:
The falling edge of a TTL signal at the LINE SYNC A input triggers each individual exposure of the sensor line
by line.
The SK2048MVSH line scan camera enables extended synchronization control by means of a second trigger
input LINE SYNC B. A detailed description can be found .under 5.2 Advanced Synchronization Control (p.
24).
2. Frame synchronization:
The recording of a set of lines (frame) representing a two-dimensional image is started by the falling edge of a
TTL signal at the FRAME SYNC input.
The configuration of the synchronization behavior is done with the parameter SkTriggerMode and following in the
section Camera Head Feature of the device feature List, see Camera Head Feature (p. 18)
Free Run / SK Mode 0
The acquisition of each line is synchronized internally (free-running) and the next scan is started automatically
after completion of the previous line scan. The line frequency is determined by the programmed value.
LineStart / SK Mode 1
After an external trigger pulse, the currently exposed line is read out at the next internal line clock. The start and
duration of the exposure are controlled internally by the camera and are not affected by the trigger pulse. The
exposure time is programmable. The line frequency is determined by the frequency of the trigger signal.
Limitations: The period of the trigger signal must be longer than the exposure time used. Between the external
trigger signal and the internally generated line clock, jitter occurs in the range of the exposure time.
ExposureActive / SK extSOS (Mode 5)
The exposure time and the line frequency are controlled by the external trigger signal. This affects both the start of
a new exposure (Start of Scan-Pulse, SOS) and the readout of the previously exposed line.
FRAME SYNC
LINE SYNC
Video
Video Valid
Data transmission
Combined frame and line synchronization
FrameTrigger / SK FrameSync
The camera suppresses the data transfer until a falling
edge of a TTL signal occurs at the FRAME SYNC
input. This starts the acquisition of a 2D area scan.
The number of image lines must be programmed in
advance. Any of the available line synchronization
modes can be used for the individual line scans.

SkLineRate Returns the line frequency in kHz, for information
only.
Read only
SkDecouplingLineFrequency TRUE= Allows shorter exposure time than the re-
ciprocal line frequency. Only selectable for camera
types with integration control.
FALSE= Line frequency and exposure time are syn-
chronized. The line frequency is the reciprocal of the
exposure time, and vice versa.

see Synchronization Modes (p. 13).
Read/write
SkFrameTrigger Selects "Frame Sync" for external trigger of images,
see Synchronization Modes (p. 13)
TRUE = "Frame Trigger" is active, i.e. the acquisition
of a 2D area scan is started by the negative edge of
the FrameSync signal. Each line is triggered accor-
ding to the adjusted LineSync mode (SkTriggerMode)
FALSE = "Frame Trigger" is off.
Command
SkFrameTriggerDelay Delay of starting the grabbing after incoming Frame-
Sync trigger signal, specified in lines
Read/write
SkOutputSignal 0 = Default, simple line signal of the camera
1 = the camera provides a saw tooth as test pattern
2 = the Shading Correction is active
3 = takes the current line signal as reference for
Shading Correction
4 = writes back the flash memory to the Shading
Correction Memory (SCM)
5 = writes SCM into the flash memory of the camera
6 = the content of SCM is displayed
7 = the 2nd flash memory is written into the 2nd SCM
8 = the content of the 2nd SCM is written into the
2nd flash memory
9 = the content of the lookup table is displayed
Note: The SkOutputSignal feature corresponds to
the serial command (“Txxxxx”, xxxxx= 0 … 9)
Read/write x
SkSetShadingCorrection ON = Incomming line signals will be scaled by the
content of the Shading Correction Memory (SCM).
For writing new SCM scale factors, using the SkLi-
neScan tool is recommended.
