sors for Baumer HXC cameras are displayed in the following graphs. The characteristic
curves for the sensors do not take the characteristics of lenses and light sources without
lters into consideration, but are measured with an AR coated cover glass.

All cameras of the HXC series are equipped with a global shutter.

ing sensor with global
shutter

Global shutter means that all pixels of the sensor are reset and afterwards exposed for a
specied interval (texposure).
For each pixel an adjacent storage circuit exists. Once the exposure time elapsed, the
information of a pixel is transferred immediately to its circuit and read out from there.
Due to the fact that photosensitive area gets "lost" by the implementation of the circuit
area, the pixels are equipped with microlenses, which focus the light on the pixel.
Digitization Taps6.2.4
The Truesense sensors, employed in Baumer HXC cameras can be read out up to 16
channels in parallel.
Notice
More channels increase the speed (framerate), but the use of more channels produces
a higher heat generation. Use only the maximum required number of channels!
Notice
Due to sensor characteristics in 12 bit mode only 2 or 4 channels are available.

Timings6.3
Notice
Overlapped mode can be switched off with setting the readout mode to sequential shut-
ter instead of overlapped shutter.
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.
The exposure time (texposure) can be adjusted by the user, however, the time needed for the
readout (treadout) is given by the particular sensor, image format and conguration.
Baumer HXC cameras can be operated with two modes, the Free Running Mode and the
Trigger Mode.
The cameras can be operated non-overlapped*) or overlapped. Depending on the mode
used, and the combination of exposure and readout time:
Non-overlappedOperation OverlappedOperation
Here the time intervals are long enough
to process exposure and readout succes-
sively.
In this operation the exposure of a frame
(n+1) takes place during the readout of
frame (n).

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

6.3.2 Trigger Mode
After a specied external event (trigger) has occurred, image acquisition is started. De-
pending on the interval of triggers used, the camera may operate non-overlapped or over-
lapped in this mode, when overlapped mode is enabled.
With regard to timings in the trigger mode, the following basic formulas need to be taken
into consideration:
Case Formula
texposure < treadout
(1) tearliestpossibletrigger(n+1) = treadout(n) - texposure(n+1)
(2) tnotready(n+1) = texposure(n) + treadout(n) - texposure(n+1)
texposure > treadout
(3) tearliestpossibletrigger(n+1) = texposure(n)
(4) tnotready(n+1) = texposure(n)
6.3.2.1 OverlappedOperation:texposure(n+2) = texposure(n+1)
In overlapped operation attention should be paid to the time interval where the camera is
unable to process occuring trigger signals (tnotready). This interval is situated between two
exposures. When this process time tnotready has elapsed, the camera is able to react to
external events again.
After tnotready has elapsed, the timing of (E) depends on the readout time of the current im-
age (treadout(n)) and exposure time of the next image (texposure(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, tnotready remains the same from acquisition to acquisi-
tion.

OverlappedOperation:t6.3.2.2 exposure(n+2) > texposure(n+1)
If the exposure time (texposure) is increased from the current acquisition to the next acquisi-
tion, the time the camera is unable to process occuring trigger signals (tnotready) is scaled
down.
This can be simulated with the formulas mentioned above (no. 2 or 4, as is the case).

6.3.2.3 OverlappedOperation:texposure(n+2) < texposure(n+1)
If the exposure time (texposure) is decreased from the current acquisition to the next acquisi-
tion, the time the camera is unable to process occuring trigger signals (tnotready) is scaled
up.
When decreasing the texposure such, that tnotready exceeds the pause between two incoming
trigger signals, the camera is unable to process this trigger and the acquisition of the im-
age will not start (the trigger will be skipped).

6.3.2.4 Non-overlappedOperation

The surface of the camera may be hot during operation and immediately

longer period.
It is very important to provide adequate dissipation of heat, to ensure that the housing
temperature does not reach or exceed +65°C (+149°F). As there are numerous possibili-
ties for installation, Baumer do not speciy a specic 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▪
*) Please refer to the respective data sheet.
**) Measured at temperature measurement point (T).

7. Software
7.1 BaumerGAPI
Baumer GAPI stands for Baumer “Generic Application Programming Interface”. With this
API Baumer provides an interface for optimal integration and control of Baumer cameras.
This software interface allows changing to other camera models.
It provides interfaces to several programming languages, such as C, C++ and the .NET™
Framework on Windows®, as well as Mono on Linux® operating systems, which offers the
use of other languages, such as e.g. C# or VB.NET.
The HXC camera features are in general supported by Baumer GAPI v 1.7.2. However,
to use the new release 2 features (e.g. HDR and Multi-ROI) Baumer GAPI v 2.1 is re-
quired.
Notice
There is currently no Baumer GAPI version for Linux available with support for
Camera Link®.
Notice
Please note the extra instructions to the software Baumer GAPI. Specically for
Camera Link® Cameras, the "User´s Guide CLCong Tool".
