1.7 Quickstart
21
If you have more than one mvHYPERION in your PC you will need a device node per card:
mknod /dev/hyperion0 c 64 0
mknod /dev/hyperion1 c 64 1
mknod /dev/hyperion2 c 64 2
mknod /dev/hyperion3 c 64 3
(e) The mvIMPACT Acquire libraries look for camera definition files in the directory
"/etc/matrix-vision/mvimpact-acquire/camerafiles"
so you will need to create these directories as the
"root"
user using
"mkdir -p /etc/matrix-vision/mvimpact-acquire/camerafiles"
.
You should download the camera definitions for your camera from the MATRIX VISION website and
copy them to this directory.

Connecting a camera
To connect a camera, for example via CameraLink cable to the mvHYPERION-CLx frame grabber, please do the
following:
• Connect the cable from the camera (labeled with e.g. Data channel 1) to the first connector J1 of the mvH
←
-
YPERION frame grabber.
• Optionally, if you are using a Medium or Full, connect the cable from the camera (labeled with e.g. Data
channel 2) to the second connector J2 of the mvHYPERION.
• Optionally, use the connector J3 to power the camera.
Make sure that you do not mix up the channels. For this, please have a look at chapter
Technical Data
(p.
where to find the specific connectors.
• Afterwards, start
wxPropView
(p.
) and choose the "Generic" camera definition.
• Now, press the
Live
button - at this point you should see something from the camera.
• Then, create a new camera definition.
• Finally, export the new camera definition and choose it in
"wxPropView -
>
ImageSetting -
>
Camera -
>
Type"
.

Settings behavior during startup
Settings
contain all the parameters that are needed to prepare and program the device for the image capture. Every
image can be captured with completely different set of parameters. In almost every case, these parameters are
accessible via a property offered by the device driver. A setting e.g. might contain
• the gain to be applied to the analog to digital conversion process for analog video sources or
• the AOI to be captured from the incoming image data.
So for the user a setting is the one an only place where all the necessary modifications can be applied to achieve
the desired form of data acquisition.
Now, whenever a device is opened, the driver will execute following procedure:
