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 damage to the eyes or skin.

Do not look directly into the light beam!

Mechanics Warning

Ensure that the motion device and the scan way is free to move and that no obstacles are in

the way.

Do not place any part of the body in the way of moving parts!

Line scan cameras are mostly used in combination with a motion device such as a translation

stage, a conveyer or a rotational drive, as well as with high intensity light sources.

For assembly close down these devices whenever possible. Beyond that, please consider the

following warnings:

conﬁguration

Normally, functions like Shading Correction, signal

modification with a look-up table (LUT) or the definition of

a region of interest (ROI) are implemented in the grabber

board. For special requirements these functions can be

made availabel within the camera, please contact the

Schäfter + Kirchhoff customer support where appropriate.

The camera is supplied precalibrated, with factory

settings for gain and offset. A readjustment is normally

not necessary.

The successful use of the line scan camera requires that

the complete optical system is properly set up, especially

the location of the illumination, the degree of focus of the

lens and the aperture setting. The most critical factor is

the perpendicular alignment of the sensor axis either with

the object to be measured or the direction of its relative

travel when scanned. For further guidance see section

4.2 Adjustments for Optimum Scan Results (p. 16).

The SK line scan camera series is designed for a wide

range of vision and inspection applications in both indus-

trial and scientific environments. The SK22368CTOC is

compliant with CameraLink Specification Rev 1.1.

Data acquisition requires that the grabber board conforms

to the CameraLinkTM standard. The grabber board

provides the Start-Of-Scan (SOS) signals and thereby

determines the exposure time and line frequency of the

camera.

CameraLink reads the camera specifications from confi-

guration files. Prior to the iniatial start-up, the appropriate

camera specific file must be created for the grabber in

use.

Beyond, the configuration program SkCLConfig allows

the full parameterization of the camera settings, such as

gain, offset and pixel frequency, via the CameraLinkTM

serial port interface. SkCLConfig uses the clser*.dll driver

that is supplied with the CameraLink grabber board.

For the development of custom applications use the

software development kits released from the grabber

board producers.

1.2 Computer System Requirements

1.3 SK22368CTOC Line Scan Camera - Specifications

Introduction

The SK22368CTOC is compliant with CameraLink

Specification Rev 1.1. It is operated in the "Base Confi-

guration" where the signals are carried over a single

connector/cable.

Power supply is provided by a separate power

connector.

Along with the camera the Schäfter +Kirchhoff confi-

guration program SkCLConfig is delivered. Provided

a clser**.dll driver by the grabber board manufacturer

is available, this program facilitates transferring the Set

and Request commands for camera configuration (see

page 13).

Installation and Setup

Instruction Manual SK22368CTOC shared_Installation-Mechanic_Axx-BGx_ML.indd

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.

The differential LVDS signals X0-X3 and XCLK are reserved for the transmission

of high-speed video data from the camera to the grabber board. The video data

is transmitted using numerous serial channels simultaneously, according to the

protocol for the channel link chipset from National Semiconductor.

The CameraLink standard defines the names of the pixel signals, the description of

the signal level and the pin assignments and pinout of the chip.
