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 Transmission).
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

6. Installation
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!

Caution
If the camera is connected to an USB2.0 port image transmission is
disabled by default. The camera consumes more than 2.5W which is the
maximum allowed by the USB2.0 specication. But there is a possibility to
activate the image transmission at your own risk!
This activation could damage your computer´s hardware!
Procedure
1. Open the camera in the Camera Explorer.
2. Select the Prole GenICam Guru.
3. Activate the Feature USB2 Support Enable in the category
Device Control.
4. Disconnect the data connection of the camera to the USB 2.0 port.
5. Connect the data connection of the camera to the USB 2.0 port.
→ Images will be transmitted via the USB 2.0 port.

8.3 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
*)
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 successively.
In this operation the exposure of a frame
(n+1) takes place during the readout of
frame (n).

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.

8.3.2 Single Frame Mode
In this mode the camera is captured one frame after AcquisitionStart. Then the acquisition
is stopped.
8.3.3 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.
8.3.4 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.
