2. General Safety Instructions
Caution
Heat can damage the camera. Provide adequate dissipation of heat, to
ensure that the temperature does not exceed the value (see Heat Trans-
mission).
As there are numerous possibilities for installation, Baumer recommends
no specic method for proper heat dissipation, but suggest the following
principles:
▪ operate the cameras only in mounted condition
▪ mounting in combination with forced convection may provide proper heat
dissipation
Caution
Observe precautions for handling electrostatic sensitive devices!
Caution
Class A
The camera is a class A device (DIN EN 55022:2011). It can cause radio
interference in residential environments. Should this happen, you must take
reasonable measures to eliminate the interference.

Caution
Device heats up during operation.
Skin irritation possible.
Do not touch the camera during operation.
Caution
Heat can damage the camera. Provide adequate dissipation of heat, to
ensure that the temperatures does not exceed the value (see table below).
As there are numerous possibilities for installation, Baumer recommends
no specic method for proper heat dissipation, but suggest the following
principles:
▪ operate the cameras only in mounted condition
▪ mounting in combination with forced convection may provide proper heat
dissipation

4.2.1 EmergencyshutdownatOvertemperature(≥Rel.2only)
To prevent damage on the hardware due to high temperatures, the camera is equipped
with an emergency shutdown. The DeviceTemperatureStatusTransitionSelector (Catego-
ry: Device Control) feature allows you to select different thresholds for temperatures:
NormalToHigh: freely programmable value
HighToExeeded: xed value (camera shutdown if exceeded)
ExeededToNormal: freely programmable value, temperature for error-free re-ac-
tivation of the camera.
In the DeviceTemperatureStatusTransition feature, the temperatures for the programma-
ble temperature transitions are set.
The Event EventDeviceTemperatureStatusChanged is always generated when Device-
TemperatureStatus changes.
If the temperature rises above the value set at HighToExceed, the DeviceTemperatureEx-
ceeded feature is set to True, the image recording is stopped, and the LED is set to red.
For further use, the camera must disconnected from the power supply after cooling down
or a device reset should be carried out.
The sufcient cooling is recognizable when the event EvenDeviceTemperatureStatusChanged (Device Temperature < ExceededToNormal) is output.

4.3 Lens mounting
Notice
Avoid contamination of the sensor and the lens by dust and airborne particles when
mounting the lens to the device!
Therefore the following points are very important:
▪ Install the camera in an environment that is as dust free as possible!
▪ Keep the dust cover (bag) on camera as long as possible!
▪ Hold the camera downwards with unprotected sensor.
▪ Avoid contact with any optical surface of the camera!
26
4.4 VCXG.I / .I.XT IP Protection classes
Notice
Denition IP65 / IP67
IP65 say that the camera housing is dust tight and hose-proof. That means it is protected against water jet that is projected by a nozzle striking the housing from any direction.
IP67 stands for dust tightness besides the protection against submersion into 1 meter
deep water for up to 30 minutes. The desired protection level is given as long as the
difference in temperature between camera and water is less than 5 K and the water has
a temperature of 15 °C (+ 59 °F) ... 35 °C (+ 95 °F).
Caution
IP
Protection
In order to achieve the mentioned IP protection level, please note the following information:
The tube needs to be screwed on gap-free as shown in the gure below.
The M12 connectors need to be tightened with a torque value of 0.4 Nm.
For that Baumer suggests the use of a torque driver (such as Wiha
TorqueVario
®
-S ESD) in combination with a wrench for assembling sensor/
actuator cables with M12 connector (such as Phoenix Contact SAC BIT
M12-D15).
Sealing rings
The peak torque while
tightening the
screws is 0.9 Nm.
Use a torque wrench!
Do not forget the seals!

6.1.2 Sensor Shutter Mode (only cameras with Rolling Shutter sensor)
Sets the sensor shutter mode of the camera. The sensor shutter mode depends on the
Trigger Mode.
An explanation of the various sensor shutter modes can be found in the next chapters.

For cameras with rolling shutter sensor and set shutter mode Global Reset, for each frame
all of the lines start exposure at the same time but the end of exposure is delayed by the
offset of the previous line's readout. The exposure time for each line gradually lengthens.
Data readout for each line begins immediately following the line's exposure. The readout
time for each line is the same, but the start and end times are staggered.
An advantage of this shutter mode is a reduction in image artifacts typical of rolling
shutters. However, because exposure lengthens throughout the frame, there may be a
gradual increase in brightness from top to bottom of an image.

For cameras with rolling shutter sensor and set shutter mode Rolling Shutter, for each
frame each line begins exposure at an offset equal to each line's readout time. The exposure time for each line is the same, but the start and end times are staggered. Data
readout for each line begins immediately following the line's exposure. The readout time
for each line is the same, but the start and end times are staggered.
One advantage of a Rolling Shutter is increased sensitivity. However, because exposure
starts at different times throughout the frame, there are known artifacts such as skew,
wobble, and partial exposure.
Notice
Due to technical issues of rolling shut-
ter, a ash control
depending on the exposure time does not
make sense.
Such cameras should
be used in a continuously illuminated environment.

6.3 Acquisition Modes and Timings
The image acquisition consists of two separate, successively processed components.
Exposing the pixels on the photosensitive surface of the sensor is only the rst part of the
image acquisition. After completion of the rst step, the pixels are read out.
Thereby the exposure time (t
exposure
) can be adjusted by the user, however, the time need-
ed for the readout (t
readout
) is given by the particular sensor and image format.
Baumer cameras can be operated with differtent acquisition modes, the Continuous
Mode (Free Running Mode), the Acquisition Frame Rate Mode, the Single Frame Mode,
the Multi Frame Mode and the Trigger Mode.
The cameras can be operated non-overlapped
1)
or overlapped. Depending on the mode
used, and the combination of exposure and readout time:
Non-overlappedOperation OverlappedOperation
Here the time intervals are long enough
to process exposure and readout successively.
In this operation the exposure of a frame
(n+1) takes place during the readout of
frame (n).

6.3.1 Continuous Mode (Free Running Mode)
In the Continuous mode the camera records images permanently and sends them to the
PC. In order to achieve an optimal result (with regard to the adjusted exposure time t
exposure
and image format) the camera is operated overlapped.
In case of exposure times equal to / less than the readout time (t
exposure
≤ t
readout
), the maximum frame rate is provided for the image format used. For longer exposure times the
frame rate of the camera is reduced.

6.3.2 Single Frame Mode
In this mode the camera is captured one frame after AcquisitionStart. Then the acquisition
is stopped.
6.3.3 Multi Frame Mode
In this mode a predened number of frames will be captured after AcquisitionStart. The
AcquisitionFrameCount controls the number of captured frames. Then the acquisition is
automatically stopped.
6.3.4 Acquisition Frame Rate Mode
With this feature Baumer introduces a clever technique to the CX camera series, that
enables the user to predene a desired frame rate in continuous mode.
For the employment of this mode the cameras uses an internal clock generator that creates trigger pulses.
Notice
From a certain frame rate, skipping internal triggers is unavoidable. In general, this depends on the combination of adjusted frame rate, exposure and readout times.
51
6.3.5 Trigger Mode
After a specied external event (trigger) has occurred, image acquisition is started. Depending on the interval of triggers used, the camera operates non-overlapped or overlapped in this mode.
With regard to timings in the trigger mode, the following basic formulas need to be taken
into consideration:

6.3.5.1 OverlappedOperation:t
exposure(n+2)
= t
exposure(n+1)
In overlapped operation attention should be paid to the time interval where the camera is
unable to process occuring trigger signals (t
notready
). This interval is situated between two
exposures. When this process time t
notready
has elapsed, the camera is able to react to
external events again.
After t
notready
has elapsed, the timing of (E) depends on the readout time of the current im-
age (t
readout(n)
) and exposure time of the next image (t
exposure(n+1)
). It can be determined by the
formulas mentioned above (no. 1 or 3, as is the case).
In case of identical exposure times, t
notready
remains the same from acquisition to acquisi-
tion.

If the exposure time (t

tion, the time the camera is unable to process occurring trigger signals (t

) is scaled
down.
This can be simulated with the formulas mentioned above (no. 2 or 4, as is the case).

If the exposure time (t

notready
) is scaled
up.
When decreasing the t
exposure
such, that t
notready
exceeds the pause between two incoming
trigger signals, the camera is unable to process this trigger and the acquisition of the image will not start (the trigger will be skipped).

6.3.6 Timings of the image transmission
6.3.6.1 VCXG
Trigger Mode
The transfer of the rst image starts after data for a complete packet size is stored in
camera's TX memory. All further images start the transfer immediately after the rst one
is completed, if the camera works in burst mode with a high frame rate and the sensor
acquires images faster than the interface can transfer. These additional pictures are not
referenced to the time of the readout. If the sensor is triggered slowly enough, each image
will behave like the rst image.
Freerun Mode
The transfer of each image starts after data for a complete packet size is stored in the
camera's TX memory. Since the sensor delivers more data than the interface can manage, depending on set ROI, images are repeatedly discarded and not transferred. Therefore, gaps of different sizes can be created via the GigE interface.
6.3.6.2 VCXU
Trigger Mode
All images are written from sensor into memory as long as free buffers are available. If
this burst memory is full, all following images are discarded by the sensor. The transfer of
the rst image starts with a small delay (about 2 lines). The data is read from the memory
and transferred to the interface. The interface can now control reading from memory. De-
pending on the USB conguration (ThroughputLimit, blank packages), the interface can
retrieve the data quickly enough or is lagging.
Freerun Mode
Only one alternating buffer is provided in the memory. The rst image is written into the
memory and immediately transferred to the interface with a small delay. The second image from the sensor is written into another buffer, which would be transferred immediately
afterwards. If the interface is too slow due to the current conguration and the rst image
has not yet been transferred completely when the third image is already received from
the sensor, the third image would overwrite the second one and would be transferred via
the interface next.

6.3.7.8 DeviceTemperaturStatusChanged
To prevent damage on the hardware due to high temperatures, the camera is equipped
with an emergency shutdown. The DeviceTemperatureStatusTransitionSelector (Catego-
ry: Device Control) feature allows you to select different thresholds for temperatures:
NormalToHigh: freely programmable value
HighToExeeded: xed value (camera shutdown if exceeded)
ExeededToNormal: freely programmable value, temperature for error-free re-ac-
tivation of the camera.
In the DeviceTemperatureStatusTransition feature, the temperatures for the programma-
ble temperature transitions are set.
The Event EventDeviceTemperatureStatusChanged is always generated when Device-
TemperatureStatus changes.
If the temperature rises above the value set at HighToExeeded, the DeviceTemperature-
Exceeded feature is set to True, the image recording is stopped, and the LED is set to red.
For further use, the camera must disconnected from the power supply after cooling down
or a device reset should be carried out.
The sufcient cooling is recognizable when the event DeviceTemperatureStatus- Changed
(Device Temperature < ExceededToNormal) is output.

7. Camera Functionalities
7.1 Image Acquisition
7.1.1 Image Format
A digital camera usually delivers image data in at least one format - the native resolution
of the sensor. Baumer cameras are able to provide several image formats (depending on
the type of camera).
Compared with standard cameras, the image format on Baumer cameras not only in-
cludes resolution, but a set of predened parameter.
These parameters are:
▪ Resolution (horizontal and vertical dimensions in pixels)
▪ Binning Mode

7.1.2 Pixel Format
On Baumer digital cameras the pixel format depends on the selected image format.
7.1.2.1 GeneralDenitions
RAW: Raw data format. Here the data are stored without processing.
Bayer: Raw data format of color sensors.
Color lters are placed on these sensors in a checkerboard pattern, generally
in a 50% green, 25% red and 25% blue array.
Mono: Monochrome. The color range of mono images consists of shades of a single
color. In general, shades of gray or black-and-white are synonyms for monochrome.
RGB: Color model, in which all detectable colors are dened by three coordinates,
Red, Green and Blue.
Red
Gree
n
Blue
Black
White
The three coordinates are displayed within the buffer in the order R, G, B.
BGR: At BGR the interface of the camera mirrors the order of transmission of the color
channels from RGB to BGR.
This can save processing power on the computer, because these data can be
processed by the graphic card without conversion.
◄Figure22
Sensor with Bayer
Pattern
◄Figure23
RBG color space displayed as color cube.
64
Pixel depth: In general, pixel depth denes the number of possible different values for
each color channel. Mostly this will be 8 bit, which means 2
8
different "col-
ors".
For RGB or BGR these 8 bits per channel equal 24 bits overall.
Two bytes are needed for transmitting more than 8 bits per pixel - even if the
second byte is not completely lled with data. In order to save bandwidth, the
packed formats were introduced to Baumer CX cameras. In this formats, the
unused bits of one pixel are lled with data from the next pixel.

7.1.3 Exposure Time
On exposure of the sensor, the inclination of photons produces a charge separation on
the semiconductors of the pixels. This results in a voltage difference, which is used for
signal extraction.
Light
Photon
Pixel
Charge Carrie
r
The signal strength is inuenced by the incoming amount of photons. It can be increased
by increasing the exposure time (t
exposure
).
Notice
Due to the sensor, xed pattern noise effects can occur at high exposure times. You
can counteract this by setting the gain to a value of approximately 1.5 and reducing the
exposure time accordingly.
Notice
In order to set a short exposure time for cameras with release 2.1, the Short Exposure
Time Enable feature must be enabled.
If the feature Short Exposure Time Enable is enabled and the exposure time is changed
e.g. from 20 μsec to lower than 15 μsec, this will change the internal parameters of the
sensors and the sensor needs to reinitialize.
This initialization sequence takes about 50 msec. This process is only necessary, if the
exposure range is changed. If the new exposure value is within the default exposure
range, no initialization is necessary.
Notice
It is not possible to use the Sequencer when the feature Short Exposure Time Enable
is enabled.

7.1.4 Fixed Pattern Noise Correction (FPNC)
CMOS sensors exhibit nonuniformities that are called Fixed Pattern Noise (FPN). How-
ever it is no noise but a xed variation from pixel to pixel that can be corrected. The advan-
tage of using this correction is a more homogeneous picture which may simplify the image
analysis. Variations from pixel to pixel of the dark signal are called dark signal nonunifor-
mity (DSNU) whereas photo response nonuniformity (PRNU) describes variations of the
sensitivity. DNSU is corrected via an offset while PRNU is corrected by a factor.

7.1.5 Look-Up-Table
The Look-Up-Table (LUT) is employed on Baumer monochrome and color cameras. It
contains 212 (4096) values for the available levels. These values can be adjusted by the
user.
For color cameras the LUT is applied for all color channels together.
7.1.6 Gamma Correction
With this feature, Baumer VCX cameras offer the possibility of compensating nonlinearity
in the perception of light by the human eye.
For this correction, the corrected pixel intensity (Y') is calculated from the original intensity
of the sensor's pixel (Y
original
) and correction factor γ using the following formula (in over-
simplied version):
Y' = Y
original
γ
On Baumer VCX cameras the correction factor γ is adjustable from 0.1 to 2.
The values of the calculated intensities are entered into the Look-Up-Table. Thereby previously existing values within the LUT will be overwritten.
Notice
If the LUT feature is disabled on the software side, the gamma correction feature is
disabled, too.
Notice
For cameras with long readout times (e.g.: VCXU-201M.R / VCXU-123M) may cause
visual effects while setting a value for gamma and simultaneous image acquisition, because access to LUT is not locked against the pixel stream.
This can be prevented by stopping the camera (AcquisitionStop) before setting.

7.1.7 Region of Interest
With the "Region of Interest" (ROI) function it is possible to predene a so-called Region
of Interest (ROI) or Partial Scan. This ROI is an area of pixels of the sensor. On image
acquisition, only the information of these pixels is sent to the PC.
This function is employed, when only a region of the eld of view is of interest. It is coupled
to a reduction in resolution.
The ROI is specied by four values:
▪ Offset X - x-coordinate of the rst relevant pixel
▪ Offset Y - y-coordinate of the rst relevant pixel
▪ Width - horizontal size of the ROI
▪ Height - vertical size of the ROI

7.1.8 Binning
On digital cameras, you can nd several operations for progressing sensitivity. One of
them is the so-called "Binning". Here, the charge carriers of neighboring pixels are aggregated. Thus, the progression is greatly increased by the amount of binned pixels. By
using this operation, the progression in sensitivity is coupled to a reduction in resolution.
Higher sensitivity enables shorter exposure times.
Baumer cameras support three types of Binning - vertical, horizontal and bidirectional.
In unidirectional binning, vertically or horizontally neighboring pixels are aggregated and
reported to the software as one single "superpixel".
In bidirectional binning, a square of neighboring pixels is aggregated.
Notice
Occuring deviations in brightness after binning can be corrected with Brightness
Correction function.

In pixel formats, which are not raw formats (e.g. RGB8), the three calculated color values
(R, G, B) of a pixel will be added with those of the corresponding neighbor pixel during
binning.

7.1.9 Brightness Correction
The aggregation of charge carriers may cause an overload. To prevent this, brightness
correction was introduced. Brightness correction can be swiched on or off.
Here, three binning modes need to be considered separately:
Binninig Realization
1x2 1x2 binning is performed within the sensor, binning correction also takes
place here. A possible overload is prevented by halving the exposure time.
2x1 2x1 binning takes place within the FPGA of the camera. The binning cor-
rection is realized by aggregating the charge quantities, and then halving
this sum.
2x2 2x2 binning is a combination of the above versions.

7.2 Color Processing
The color cameras are balanced to a color temperature of 6500 K. With the feature Color
Transformation Factory List the color temperature can be switched between 6500 K and
3000 K.
Oversimplied, color processing is realized by 4 modules.

White balance
The color signals r (red), g (green) and b (blue) of the sensor are amplied in total and
digitized within the camera module.
Within the Bayer processor, the raw signals r', g' and b' are amplied by using of indepen-
dent factors for each color channel. Then the missing color values are interpolated, which
results in new color values (r'', g'', b'').
The next step is the color transformation. Here the previously generated color signals r'',
g'' and b'' are converted to optimized RGB (Color adjustment as physical balance of the
spectral sensitivities).
7.3 Color Adjustment – White Balance
This feature is available on all color cameras of the Baumer VCX series and takes place
within the Bayer processor.
White balance means independent adjustment of the three color channels, red, green and
blue by employing of a correction factor for each channel.
7.3.1 User-specicColor Adjustment
The user-specic color adjustment in Baumer color cameras facilitates adjustment of the
correction factors for each color gain. This way, the user is able to adjust the amplica-
tion of each color channel exactly to his needs. The correction factors for the color gains
range from 1 to 4.

7.4.2 Gain
In industrial environments motion blur is unacceptable. Due to this fact exposure times
are limited. However, this causes low output signals from the camera and results in dark
images. To solve this issue, the signals can be amplied by a user-dened gain factor
within the camera. This gain factor is adjustable.
Notice
Increasing the gain factor causes an increase of image noise.

7.5 Pixel Correction
7.5.1 General information
A certain probability for abnormal pixels - the so-called defect pixels - applies to the sensors of all manufacturers. The charge quantity on these pixels is not linear-dependent on
the exposure time.
The occurrence of these defect pixels is unavoidable and intrinsic to the manufacturing
and aging process of the sensors.
The operation of the camera is not affected by these pixels. They only appear as brighter
(warm pixel) or darker (cold pixel) spot in the recorded image.

7.5.2 Correction Algorithm
On Baumer cameras the problem of defect pixels is solved as follows:
▪ Possible defect pixels are identied during the production process of the camera.
▪ The coordinates of these pixels are stored in the factory settings of the camera.
▪ Once the sensor readout is completed, correction takes place:
▪ Before any other processing, the values of the neighboring pixels on the left and the
right side of the defect pixels, will be read out. (within the same bayer phase for
color)
▪ Then the average value of these 2 pixels is determined to correct the rst defect
pixel
▪ Finally, the value of the second defect pixel is is corrected by using the previously
corrected pixel and the pixel of the other side of the defect pixel.

7.5.3 Add Defect Pixel to Defectpixellist
As stated previously, this list is determined within the production process of Baumer cameras and stored in the factory settings.
Additional hot or cold pixels can develop during the lifecycle of a camera. In this case
Baumer offers the possibility of adding their coordinates to the defectpixellist.
The user can determine the coordinates
1)
of the affected pixels and add them to the list.
Once the defect pixel list is stored in a user set, pixel correction is executed for all coordinates on the defectpixellist.
Notice
There are defect pixels, which occur only under certain environmental parameters.
These include temperatures or exposure settings.
Complete defect pixels that occur in your application.
Procedure
1. Start the Camera Explorer. Connect to the camera. Select the prole GenICam
Expert.
2. Open the category LUT Control.
3. Locate an empty Defect Pixel List Index.
(Defect Pixel List Entry PosX = 0 / Defect Pixel List Entry PosY = 0)
Avoid using existing coordinates!
4. Determine the coordinates of the defect pixel. Keep the mouse pointer over the
defect pixel. The coordinates of the defect pixel is displayed in the status bar.
For simplication, you can enlarge the image.
5. Enter the determined coordinates for X (Defect Pixel List Entry PosX).
Enter the determined coordinates for Y (Defect Pixel List Entry PosY).
6. Activate the registered Defect Pixel List Index (Defect Pixel List Entry Active =
True).
7. Stop the camera and start them again to take over the updated coordinates.
8. Save your settings in a User Set (Category: User Set Control). Coordinates,
which are not stored in an user set will be lost after power reset.
1) Position in relation to Full Frame Format (Raw Data Format / No ipping).

7.6 Process Interface
7.6.1 Digital-IOs
7.6.1.1 UserDenableInputs
The wiring of these input connectors is the responsibility of the user.
The sole exception to this is the compliance with predetermined high and low levels
(only the optical input IN1; 0 ... 4.5V low, 11 ... 30V high).
The dened signals will have no direct effect, but can be analyzed and processed on the
software side and used to control the camera.
Using a so called "IO matrix" allows you to select the signal and the state to be processed.
On the software side, the input signals are named "Trigger", "Timer" and "LineOut 1...3".
* Example, if the two GPIO's are used as input. (only VCXG / VCXU)

7.6.1.5 Pulse Width Modulated Outputs (only VCXG.I/.I.XT)
With the function Pulse Width Modulated Outputs (PWM) it is possible to control an illumination controller or an illumination directly connected to the camera in various ways. The
set LineSource is used as a signal for the control.
Caution
Erroneous settings can destroy the illumination! The outputs of the camera
are protected against destruction. Please follow the information in the data
sheets for your illumination. Contact the manufacturer of the illumination if
you are unsure about admissible parameters.
Setting a output to a specic illumination
1. Set LinePWMCongurationMode to true
2. Set at LinePWMMaxDutyCycle and LinePWMMaxDuration the
maximum admissible parameters of your illumination (e.g. Falcon
FLDR-i90B-IR24).
LinePWMMaxDutyCycle = 10 %
LinePWMMaxDuration = 10 ms
3. Set LinePWMCongurationMode to false.
→ The values set in step 2 are now the max. admissible parameters.

7.6.4 Debouncer
The basic idea behind this feature was to seperate interfering signals (short peaks) from
valid square wave signals, which can be important in industrial environments. Debouncing
means that invalid signals are ltered out, and signals lasting longer than a user-dened
testing time t
DebounceHigh
will be recognized, and routed to the camera to induce a trigger.
In order to detect the end of a valid signal and lter out possible jitters within the signal, a
second testing time t
DebounceLow
was introduced. This timing is also adjustable by the user.
If the signal value falls to state low and does not rise within t
DebounceLow
, this is recognized
as end of the signal.
The debouncing times t
DebounceHigh
and t
DebounceLow
are adjustable from 0 to 5 msec in steps
of 1 μsec.

can be used optimally in industrial environments.

7.6.5.1 ExposureActiveDelay
As previously stated, the Timer feature can be used to start the connected illumination
earlier than the sensor exposure.
This implies a timer conguration as follows:
▪ The ash output needs to be wired to the selected internal Timer signal.
▪ Trigger source and trigger activation for the Timer need to be the same as for the
sensor exposure.
▪ The TimerDelay feature (t
TimerDelay
) needs to be set to a lower value than the trigger
delay (t
triggerdelay
).
▪ The duration (t
TimerDuration
) of the timer signal should last until the exposure of the sensor
is completed. This can be realized by using the following formula:
t
TimerDuration
= (t
triggerdelay
– t
TimerDelay
) + t
exposure
7.6.6 Timer
Timers were introduced for advanced control of internal camera signals.
The timer conguration includes four components:
Setting Description
Timeselector There are one timer. Own settings for this timer can be
made. (Timer1).
TimerTriggerSource This feature provides a source selection for each timer.
TimerTriggerActivation This feature selects that part of the trigger signal (edges or
states) that activates the timer.
TimerDelay This feature represents the interval between incoming trig-
ger signal and the start of the timer.
(0 μsec .. 2 sec, step: 1 μsec)
TimerDuration By this feature the activation time of the timer is adjustable.
(10 μsec .. 2 sec, step: 1 μsec)
Different Timer sources can be used:
Timer Trigger Sources
ExposureEnd Line2 (VCXG.I / .I.XT)
ExposureStart Line3 (VCXG.I / .I.XT)
Frame Transfert Skipped Off
Line0 Software
Line1 (VCXG.I / .XT) TriggerSkipped
97
7.6.7 Counter (≥Rel. 2 only)
You can choose between two counters (Counter Selector). With each of this counters you
can count the events in the table below. The count values of the events are readable and
writable.
With the feature Counter Trigger Source you can specify which event should be counted.
These events can also be used as a counter reset source.
These events are:
CounterEventSources
Counter2End FrameTrigger
ExposureActive Off
FrameTransferSkipped TriggerSkipped
You can set a counter duration too. You can therefore set the number of events to
be counted. When the set value is 0, then the maximum number of countable events
is 2
32
-1.
If you specify a value, then the counter counts up to that value and stops. Then a GigE
event is triggered ("Counter1/2End") and the status of the counter changes from ACTIVE
to the readable status COMPLETED.
Reset the counter
When the reset event is reached or the counter is reset by software with "Counter Reset",
98
7.7 Sequencer(≥Rel.2only)
The Sequencer enables the possibility of image series recording including automated
re-parameterization of the camera based on different events and signals. Therefore the
desired camera settings for each step are stored in so called sequencer sets.
Stringing together a number of these sequencer sets results in a sequence. The connection of sequences is done by using different paths. Alongside the camera features the
path related features are also part of a sequencer set.
7.7.1 Sequencer sets
Sequencer sets combine camera features – comparable with a user set – and sequencer
(set and path) related parameters.
Settings for several camera features such as:
▪ exposure time
▪ gain
▪ partial scan
▪ user output
▪ counter
can be controlled by the sequencer and thus stored to a sequencer set as well as information for the set switch-over via four different paths.

Each path involves:

feature
▪ the signal, whose change of state is used for triggering the set switch-over and that is
mapped as SequencerTriggerSource
▪ the change of state triggering the set switch-over and that is mapped as ‘Sequencer-
TriggerActivation’
As with user sets the camera’s current settings are overwritten once a sequencer set is
loaded and the sequencer is activated.
99
7.7.2 Sequencerconguration
In order to avoid overwriting current camera settings while conguring a sequencer, the
camera needs to be set to the sequencer conguration mode.
Once the camera is set to the sequencer conguration mode, the individual sequencer
sets can be selected via the SequencerSetSelector, congured and saved by executing
SequencerSetSave.
Starting the congured sequence requires to switch the sequencer conguration mode off
and to enable the sequencer mode.
