The mvIMPACT Acquire manual for the MATRIX VISION frame grabbers is based on a modular concept. That
means like in many object-oriented programming languages you have for each functionality your own "class". Instead of classes, you have books. For example, if you want to know how images are acquired with the frame
grabbers, have a look in the respective programming language chapter.
Here is a short summary about all books of the frame grabber manual:
• The manual starts with technical data of the frame grabber as well as a quick start chapter.
Afterwards, you will find the different books:
• Application Usage (p. 48)
– The frame grabbers can also be managed via user interface. The program is called wxPropView (p. 48).
• DirectShow developers (p. 115)
– This is the documentation of the MATRIX VISION DirectShow_acquire interface.
• Use cases (p. 122)
– This book offers solutions and explanations for standard use cases.
Note
For C, C++, .NET developers, there are separate mvIMPACT Acquire manuals
• "mvIMPACT_Acquire_API_CPP_manual.chm",
• "mvIMPACT_Acquire_API_C_manual.chm", and
• "mvIMPACT_Acquire_API_NET_manual.chm"
available as downloads from our website http://www.matrix-vision.com. The manuals contain
chapter about
• how to link and build applications using mvIMPACT Acquire,
• how the log output for "mvIMPACT Acquire" devices is configured and how it works in general,
• how to create your own installer packages for Windows and Linux, and
• the general mvIMPACT Acquire API documentation.
1.2How to get started?
1.2.1 Introduction
This chapter gives you a short overview, how to get started with a MATRIX VISION frame grabber and where to find
the necessary information in the manual. It will also explain or link to the concepts behind the driver and the image
acquisition. Furthermore it shows you how to get start programming own applications.

1.2.2 Basics
1.2.2.1 Driver concept
The driver supplied with the MATRIX VISION product represents the port between the programmer and the
hardware. The driver concept of MATRIX VISION provides a standardized programming interface to all image
processing products (excluding mvBlueLYNX) made by MATRIX VISION GmbH.
The advantage of this concept for the programmer is that a developed application runs without the need for any
major modifications to the various image processing products made by MATRIX VISION GmbH. You can also
incorporate new driver versions, which are available for download free of charge on our website.
The following diagram shows a schematic structure of the driver concept:
Figure 1: Driver concept
• 1 Part of any mvIMPACT Acquire driver installation package (Windows).
• 2 Separately available for 32 bit and 64 bit. Requires at least one installed driver package.
• 3 See 2, but requires an installed version of the mvBlueFOX driver.
• 4 Part of the NeuroCheck installer but requires at least one installed frame grabber driver.
• 5 Part of the mvIMPACT SDK installation. However, new designs should use the .NET libs that are now part
of mvIMPACT Acquire ("mv.impact.acquire.dll"). The namespace "mv.impact.acquire" of
"mv.impact.acquire.dll" provides a more natural and more efficient access to the same features
as contained in the namespace "mvIMPACT_NET.acquire" of "mvIMPACT_NET.dll", which is why
the latter one should only be used for backward compatibility but NOT when developing a new application.
• 6 Part of Micro-Manager.

1.2.2.2 NeuroCheck support
A couple of devices are supported by NeuroCheck. However between NeuroCheck 5.x and NeuroCheck 6.x there
has been a breaking change in the internal interfaces. Therefore also the list of supported devices differs from one
version to another and some additional libraries might be required.
For NeuroCheck 5.x the following devices are supported:
DeviceAdditional software needed
mvTITAN-G1mvSDK driver for mvTITAN/mvGAMMA devices
mvTITAN-CLmvSDK driver for mvTITAN/mvGAMMA devices

1.2.2.3 VisionPro support
Every mvIMPACT Acquire driver package under Windows comes with an adapter to VisionPro from Cognex. The
installation order does not matter. After the driver package and VisionPro has been installed, the next time VisionPro
is started it will allow selecting the mvIMPACT Acquire device. No additional steps are needed.
MATRIX VISION devices that also comply with the GigE Vision or USB3 Vision standard don't need any software
at all, but can also use VisionPro's built-in GigE Vision or USB3 Vision support.
MATRIX VISION GmbH
1.2 How to get started?5
1.2.2.4 HALCON support
HALCON comes with built-in support for mvIMPACT Acquire compliant devices, so once a device driver has been
installed for the mvIMPACT Acquire device, it can also be operated from a HALCON environment using the corresponding acquisition interface. No additional steps are needed.
MATRIX VISION devices that also comply with the GigE Vision or USB3 Vision standard don't need any software
at all, but can also use HALCON's built-in GigE Vision or USB3 Vision support.
As some mvIMPACT Acquire device driver packages also come with a GenTL compliant interface, these can also
be operated through HALCON's built-in GenTL acquisition interface.
1.2.2.5 LabVIEW support
Every mvIMPACT Acquire compliant device can be operated under LabVIEW through an additional set of VIs which
is shipped by MATRIX VISION as a separate installation ("mvLabVIEW Acquire").
MATRIX VISION devices that also comply with the GigE Vision or USB3 Vision standard don't need any additional
software at all, but can also be operated through LabVIEW's GigE Vision or USB3 Vision driver packages.
1.2.2.6 DirectShow support
Every mvIMPACT Acquire compliant device driver package comes with an interface to DirectShow. In order to be
usable from a DirectShow compliant application, devices must first be registered for DirectShow support. How to
this is explained here (p.116).
1.2.2.7 Micro-Manager support
Every mvIMPACT Acquire compliant device can be operated under https://micro-manager.org when
using mvIMPACT Acquire 2.18.0 or later and at least Micro-Manager 1.4.23 build AFTER 15.12.2016. The
adapter needed is part of the Micro-Manager release. Additional information can be found here:https←-
://micro-manager.org/wiki/MatrixVision.
1.2.3 Image acquisition concept
The image acquisition is based on queues to avoid the loss of single images. With this concept you can acquire images via single acquisition or triggered acquisition. For detailed description of the acquisition concept, please have
a look at "How the capture process works" in the mvIMPACT_Acquire_API manual matching the programming
language you are working with.
1.2.4 Installation

7.1Hardware installation
Warning
Please take all proper Electro Static Discharge (ESD) precautions during the installation of your new hardware!
Before starting the installation, turn off your computer and all peripheral devices. Disconnect the computer from the
power supply and all necessary components.
Note
To avoid doing damage to the hardware, discharge yourself of static charge by touching e.g. the casing.
Beware of touching contacts of the frame grabber or of the computer.
• Select a free busmaster slot (PCI Express). Remove the slot's cover at the back of the computer and keep
the screw.
• Carefully insert the board into the slot by holding the board at the top and gently pushing both ends into the
slot at the same time. Press onto the upper edge of the board to make sure it is seated in the slot firmly.
• Do not force the board into the slot! You run the risk of bending the contacts. If the board does not fit easily,
pull it back out, and try again.
• Fasten the board's bracket at the back of the computer using the screws you saved from the shield.
• Put the cover back on the computer and reconnect the peripheral devices.
• Start the computer.
Warning
According to the construction, if you want to connect or disconnect a PoCL (p. 120) camera, please be sure
that the PC or the mvHYPERION frame grabber is switched off! Otherwise, during the connection, the camera
or the frame grabber could be short-circuited and possibly destroyed!

Software requirements
MATRIX VISION GmbH
7.3 Linux21
• Linux x86 (32-bit)
– The 32 bit version will run on a 64-bit Linux system if the other library requirements are met with 32-bit
libraries. i.e. you cannot mix 64 and 32-bit libraries and applications.
– Versions for Linux on x86-64 (64-bit), PowerPC, ARM or MIPS may be possible on request.
• GNU compiler version GCC 3.2.x or greater and associated toolchain.
Other requirements
• libexpat ( http://expat.sourceforge.net)
• Optional: wxWidgets 2.6.x (non Unicode) for the wxWidget test programs.
• Optional: udev or hotplug subsystem (see also 6. below).
As an example of which packets need to be installed, consider OpenSuSE 10.1:
• The compiler used is gcc 4.1.0 and may need to be installed. Use the "gcc" und "gcc-c++" RPMs. Other
RPMs may be installed automatically due to dependencies (e.g. make).
• libexpat will almost definitely be installed already in any software configuration. The RPM is called "expat".
• Install the wxWidgets "wxGTK" and "wxGTK-develop" RPMs. Others that will be automatically installed due
to dependencies include "wxGTK-compat" and "wxGTK-gl". Although the MATRIX VISION software does not
use the ODBC database API the SuSE version of wxWidgets has been compiled with ODBC support and the
RPM does not contain a dependency to automatically install ODBC. For this reason you must also install the
"unixODBC-devel" RPM.
• OpenSuSE 10.1 uses the udev system so a separate hotplug installation is not needed.
Hardware requirements
PC with PCI Express Single lane
Note
The driver contains libraries for Linux x86 (32 bit) or Linux 64-bit (x86_64). There are separate package files
for systems with toolchains based on GNU gcc 3.2.x - 3.3.x and those based on GNU gcc >= 3.4.x. gcc 3.1.x
may work but, in general, the older your toolchain is, the lass likely it is that it will work. Toolchainss based on
GNU gcc 2.x.x are not supported at all.
7.3.2 Installing the mvIMPACT Acquire driver
7.3.2.1 Using the installer script
To use the mvHYPERION frame grabber within Linux (grab images from it and change its settings), a driver is
needed, consisting of several libraries and several configuration files. These files are required during run time.
To develop applications that can use the mvHYPERION frame grabber, a source tree is needed, containing header
files, makefiles, samples, and a few libraries. These files are required at compile time.
Both file collections are distributed in a single package:
mvHYPERION-x86_ABI2-n.n.n.tgz
MATRIX VISION GmbH
22CONTENTS
1. Please start a console and change into a directory e.g. /home/username/workspace
cd /home/username/workspace
2. Copy the install script and the hardware driver to the workspace directory (e.g. from a driver CD or from the
website):
The install script has to be executable. So please check the rights of the file.
During installation, the script will ask, if it should build all tools and samples.
You may need to enable the execute flag with
chmod a+x install_mvHYPERION.sh
The installation script checks the different packages and installs them with the respective standard packages manager (apt-get) if necessary.
Note
The installation script ("install_mvHYPERION.sh") and the archive ("mvHYPERION-x86_AB←-
I2-n.n.n.tgz") must reside in the same directory. Nothing is written to this directory during script execu-
tion, so no write access to the directory is needed in order to execute the script.
You need Internet access in case one or more of the packages on which the GenICam™ libs depend are not yet
installed on your system. In this case, the script will install these packages, and for that, Internet access is required.
The script takes two arguments, both of which are optional:
1. target directory name
2. version
The target directory name specifies where to place the driver. If the directory does not yet exist, it will be created.
The path can be either absolute or relative; i.e. the name may but need not start with "/.".
Note
This directory is only used for the files that are run time required.
The files required at compile time are always installed in "$HOME/mvimpact-acquire-n.n.n". The script
also creates a convenient softlink to this directory:
mvimpact-acquire -> mvIMPACT_acquire-2.3.2
If this argument is not specified, or is ".", the driver will be placed in the current working directory.
The version argument is entirely optional. If no version is specified, the most recent mvHYPERION-x86_AB←-
I2-n.n.n.tgz found in the current directory will be installed.
If you have also installed tools and samples, you will find them in apps. Just change into the subdirectory, for
example, "apps/mvPropView/x86" you can find the camera setup tool wxPropView (p. 48). You can find
it in subdirectory "∼/mvimpact-acquire/apps/mvPropView/x86". However, you do not always have
to start the tool from this folder. The installer script has created symbolic links so that it is enough to type in
wxPropView throughout the system to start wxPropView (p.48).
The mvIMPACT Acquire libraries look for camera definition files in the directory "mvimpact-acquire/camerafiles"
so you will need to create these directories as the "root" user using "mkdir -p ./mvimpact-acquire/camerafiles".
MATRIX VISION GmbH
7.3 Linux23
7.3.2.2 Doing it manually
The mvHYPERION is controlled by a number of user-space libraries. It is not necessary to compile a kernel module.
1. Logon to the PC as the "root" user or start a super user session with "su". Start a console with "root"
privileges.
2. Determine which package you need by issuing the following command in a terminal window:
gcc -v
This will display a lot of information about the GNU gcc compiler being used on your system. In case of the
version number you have to do following:
3. You can now install the mvHYPERION libraries as follows:
• create a new directory somewhere on your system.
• copy the correct package file to this directory and change into this directory with "cd".
The libraries are supplied as a "tgz" archive with the extension ".tgz".
(a) Unpack the archive using "tar" e.g.:
tar xvzf mvhyperion-x86-ABI1-1.8.4.55.tgz
or
tar xvzf mvhyperion-x86-ABI2-1.8.4.55.tgz
Note
Current versions of the ABI1 libraries were compiled using a SuSE 8.1 system for maximum compatibility with older Linux distributions. These libraries should work with all SuSE 8.x and SuSE
9.x versions as well as with Debian Sarge and older Red Hat / Fedora variants.
Current versions of the ABI2 libraries were compiled using a SuSE 10.1 system for maximum
compatibility with newer Linux distributions. These libraries should work with SuSE 10.x as well
as with Ubuntu 6.06 or newer, with up-to-date Gentoo or Fedora FC5.
(b) After installing the access libraries you will see something like the following directory structure in your
directory (dates and file sizes will differ from the list below):
drwxr-xr-x10 rootroot4096 Jan 5 15:08 .
drwxr-xr-x23 rootroot4096 Jan 4 16:33 ..

The directory "lib/x86" contains the pre-compiled 32-bit libraries for accessing the mvBlueFOX.
If 64-bit libraries are supplied they will be found in "lib/x86_64". The "apps" directory contains test
applications (source code). The directories contain headers needed to write applications for the device.
Since the libraries are not installed to a directory known to the system i.e. not in the "ldconfig"
cache you will need to tell the system where to find them by...
• using the "LD_LIBRARY_PATH" environment variable,
• or copying the libraries by hand to a system directory like "/usr/lib" (or using some symbolic
links),
• or entering the directory in "/etc/ld.so.conf" and running "ldconfig".
e.g. to start the application called "LiveSnap":

Note
Please declare the device e.g. HC∗ or HC000000001
cd my_directory
LD_LIBRARY_PATH=‘pwd‘/lib/x86 apps/LiveSnap/x86/LiveSnap HC
For 64-bit it will look like this...
LD_LIBRARY_PATH=‘pwd‘/lib/x86_64 apps/LiveSnap/x86_64/LiveSnap HC
For ARM it will look like this...
LD_LIBRARY_PATH=‘pwd‘/lib/arm apps/LiveSnap/arm/LiveSnap HC

*
*
etc.
After installing the libraries and headers you may continue with "3." below as a normal user i.e. you do
not need to be "root" in order to compile the test applications. See also the note "4." below.
(c) To build the test applications type "make". This will attempt to build all the test applications contained
in "apps". If you have problems compiling the wxWidget library or application you may need to do one
or more of the following:
• install the wxWidget 3.x development files (headers etc.) supplied for your distribution. (See "Other
requirements" above).
• fetch, compile and install the wxWidget 3.x packet from source downloaded from the website (
http://www.wxwidgets.org).
• alter the Makefiles so as to find the wxWidget configuration script called wx-config.
The files you may need to alter are to be found here:
apps/mvPropView/Makefile.inc
You will find the compiled test programs in the subdirectories "apps/.../x86". For 64 bit systems
it will be "apps/.../x86_64". For ARM systems it will be "apps/.../arm".
If you cannot build the wxWidget test program you should, at least, be able to compile the text-based
test programs in apps/SingleCapture, apps/LiveSnap, etc.
The Makefile will also attempt to configure itself so that the mvHYPERION kernel module can be built.
You should see the following message at the end of the compile block:
=============================================================
To install the mvHYPERION kernel module now make sure that you are root and type:
make install
=============================================================
If you are not already logged in as the "root" user you must now use "su" to change users and type
"make install". On an Ubuntu system you might try "sudo make install". The kernel
module will now be built and installed.
Now you will have to tell your system to use this kernel module and to associate it with a device
node. To do this you need to edit the file "/etc/modprobe.conf". Depending on your system
you may have a directory called "/etc/modules.d/", where you can put files that are included
automatically in "/etc/modprobe.conf". Other systems (e.g. older SuSE) use a file called
"/etc/modprobe.conf.local" which the user may alter. Which ever way you do it, you need
to add some lines like this:
alias char-major-64hyperion
options hyperion major_dev_num=64
Afterwards, please use "depmod -a" to tell the system about this change. The lines above tell the
system to use a device called "/dev/hyperion" with a major number of 64.
(d) If you are using a system with an up-to-date version of udev you might be interested in the file "←-
Scripts/50-udev-hyperion.rules". By including this file in your udev rules directory you can tell your
system to create a device node for the mvHYPERION automatically when loading the kernel module.←-
You will need to edit the file to fit your system. As delivered, all entries are commented out.
If you do not use udev then you will have to create a device node yourself by hand. For example, you
could do the following to use major device number 64:
mknod /dev/hyperion c 64 0

7.4 Connecting a camera25
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.
7.4Connecting 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. 28),
where to find the specific connectors.
• Afterwards, start wxPropView (p.48) 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 as described in Working with camera descriptions (p. 71).
• Finally, export the new camera definition and choose it in "wxPropView -> ImageSetting -> Camera -> Type".
7.5Settings 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:
• Please note that each setting location step in the figure from above internally contains two search steps. First
the framework will try to locate a setting with user scope and if this can't be located, the same setting will be
searched with global (system-wide) scope. Under Windows® this e.g. will access either the HKEY_CURR←-ENT_USER or (in the second step) the HKEY_LOCAL_MACHINE branch in the Registry.
• Whenever storing a product specific setting, the device specific setting of the device used for storing will be
deleted (if existing). So when the user is currently working with a device 'VD000001' belonging to the product
group 'VirtualDevice' and there is a setting exclusively for this device storing a product specific setting now will
automatically delete the setting for 'VD000001'. Otherwise a product specific setting would never be loaded
as a device specific setting will always be found first.
• The very same thing will also happen when opening a device from any other application! wxPropView (p. 48)
does not behave in a special way but only acts as an arbitrary user application.
• Whenever storing a device family specific setting, the device specific or product specific setting of the device
used for storing will be deleted (if existing). See above to find out why.
• Under Windows® the driver will not look for a matching XML file during start-up automatically as the native
storage location for settings is the Windows® Registry. This must be loaded explicitly by the user by using
the appropriate API function offered by the SDK. However, under Linux XML files are the only setting formats
understood by the driver framework thus here the driver will also look for them at start-up. The device specific
setting will be an XML file with the serial number of the device as the file name, the product specific setting
will be an XML file with the product string as the filename, the device family specific setting will be an XML
file with the device family name as the file name. All other XML files containing settings will be ignored!
• Only the data contained in the lists displayed as "Image Setting", "Digital I/O" and "Device
Specific Data" under wxPropView (p.48) will be stored in these settings!
• Restoring of settings previously stored works in a similar way. After a device has been opened the settings
will be loaded automatically as described above.
• A detailed description of the individual properties offered by a device will not be provided here but can be
found in the C++ API reference, where descriptions for all properties relevant for the user (grouped together in
classes sorted by topic) can be found. As wxPropView (p.48) doesn't introduce new functionality but simply
evaluates the list of features offered by the device driver and lists them any modification made using the GUI
