1 Introduction
1.1 The Basler L200 Product Family
L200 series line scan cameras are versatile cameras designed for industrial use. Superb image
sensing features are combined with a robust, high precision machined housing.
Important features are:
• High sensitivity
• Anti-blooming
• Correlated double sampling (CDS)
• Electronic exposure time control
• High Signal-to-Noise ratio
• Single or dual video data output
• Programmable via an RS-232 serial port
• Industrial housing manufactured with high planar, parallel and angular precision
• Compact size.
L200 line scan cameras are available in different versions, varying in pixel clock frequencies. The
camera can be programmed to output video data as a single ( 8 bit ) or as a dual ( 2 * 8 bit ) output
stream. Table 1-1 lists the product family cameras.
1.1.1 Camera Name Change
In June 2000, several Basler camera models were renamed. Before June 2000, the L201 and L203
were known as the L220 and L240 respectively.

1.3 Precautions
Read the manual
Read the manual carefully before using the camera.
Keep foreign matter outside of the camera
Do not open the casing. Touching internal components may damage them.
Be careful not to allow liquid, flammable, or metallic material inside the camera housing. If
operated with any foreign matter inside, the camera may fail or cause a fire.
Ventilation
Allow sufficient air circulation around the camera or provide additional cooling to prevent internal
heat build-up.
Environmental Requirements
Housing temperature during operation: + 5° C … +50° C (+ 41° F … +122° F)
Operation humidity: 5% … 85%, relative, non-condensing
Storage temperature: -10° C … + 70° C (+ 14° F … +158° F)
Storage humidity: 5% … 95%, relative, non-condensing
Electromagnetic Fields
Do not operate the camera in the vicinity of strong electromagnetic fields. Avoid electrostatic
charging.
Transporting
Only transport the camera in its original packaging. Do not discard the packaging.
Cleaning
Avoid cleaning the surface of the CCD sensor if possible. If you must clean it, use a soft, lint free
cloth dampened with a small quantity of isopropyl alcohol. Do not use methylated alcohol.
Because electrostatic discharge can damage the CCD sensor, you must use a cloth that will not
generate electrostatic charge during cleaning (cotton is a good choice).
To clean the surface of the camera housing, use a soft, dry cloth. To remove severe stains, use
a soft cloth dampened with a small quantity of neutral detergent, then wipe dry.
Do not use volatile solvents such as benzine and thinners; they can damage the surface finish.
Warning!
Without sufficient cooling the camera can get hot enough during operation
to cause burning when touched.

2.3 Video Data and Control Signals
All video data and control signals on the L200 series cameras use LVDS technology as specified
for RS-644. Detailed information on RS-644 appears in Section 2.3.3
2.3.1 Input Signals
2.3.1.1 ExSync: Controls Line Readout and Exposure Time
The camera can be programmed to function in three basic exposure time control modes. In these
modes, edge-controlled, level-controlled and programmable, an external trigger (ExSync) signal
is used to control exposure time and line read out. For more detailed information on the three
modes, see Section 3.3.
ExSync can be a periodic or non-periodic function. The frequency of the ExSync signal
determines the camera’s line rate.
Minimum high and low level time for the ExSync signal is 3 Pclk (pixel clocks). Note that ExSync
is edge sensitive and therefore must toggle.
Note that the exposure time may vary by 2 Pclk because ExSync must synchronize internally with
the pixel clock.
2.3.2 Output Signals
2.3.2.1 LVAL: Indicates a Valid Line
LVAL indicates a valid line of data as illustrated in Figures 2-5 and 2-7 for single output operation
and in Figures 2-9 and 2-11 for dual output operation. Video data is valid when LVAL is high.
2.3.2.2 Pixel Clock: Indicates a Valid Pixel
Pixel clock indicates a valid pixel of data as illustrated in Figures 2-5 and 2-7 for single output
operation and in Figures 2-9 and 2-11 for dual output operation. The LVAL and the pixel clock
signal are used to clock the digital video output data into external circuitry. Digital data is valid on
the rising edge of the pixel clock signal with LVAL high. The pixel clock frequencies for single
output operation and for dual output operation are shown in Table 2-5.
2.3.2.3 Video Data
Depending on a camera setting, L200 cameras can output pixels either as a single data stream
as shown in Figures 2-5 and 2-7 or as two data streams as illustrated in Figures 2-9 and 2-11. For
a single data stream the pixels are in sequential order, starting with the first valid pixel and ending
with the last pixel. No further sorting is required. In dual output operation, odd and even pixels are
transferred as pairs, made up of an odd and the next following even pixel. The low byte b7- b0
transfers the odd pixels, the high byte b15 - b8the even pixels.

All video data and control signals on L200 series cameras use LVDS technology as specified for
RS-644. Basic RS-644 characteristics are outlined in Table 2-6.
L200 series cameras use National Semiconductor DS90C031 differential line drivers to generate
LVDS output signals and a National Semiconductor DS90C032 differential line receiver to receive
LVDS input signals. Detailed spec sheets for these devices are available at the National
Semiconductor web site (www.national.com).
Figure 2-13 shows a basic schematic for the input/output stage of L200 series cameras.

[4] Note that the frequency refers to the pixel clock and not the number of
pixels transferred per clock cycle
