Acquisition Applets for marathon ACL#
The functionality of a frame grabber is defined by a specific hardware-related program. This hardware implementation is called applet. For each frame grabber, several applets are available.
By loading an applet onto the frame grabber, you define the functionality of the frame grabber and adapt it to the requirements of your specific application.
The acquisition applets for marathon ACL are included in the Framegrabber SDK.
On marathon frame grabbers, an applet is available as soon as it is flashed onto the frame grabber.
Requirements#
- Host software: Framegrabber SDK (5.7, 5.10a, or higher) with hardware-dependent acquisition applets
- Hardware: A marathon ACL frame grabber is connected to your system
Limitation
In all applets, buffers larger than 4GB can't be allocated. Even if the applet allows a larger buffer size, you can't allocate buffers larger than 4GB due to limitations in the driver and firmware.
You can calculate the buffer size as follows:
Buffer size = image height * image width * (pixel width / 8).
For RGB images: buffer size = (image height * image width * (pixel width / 8)) * 3 .

Area Scan Acquisition Applets#
The following Area Scan Acquisition Applets are available:
- Acq_DualBaseAreaBayer
- Acq_DualBaseAreaGray
- Acq_DualBaseAreaRGB
- Acq_SingleBaseAreaBayer
- Acq_SingleBaseAreaGray
- Acq_SingleBaseAreaRGB
- Acq_SingleFullAreaBayer
- Acq_SingleFullAreaGray
- Acq_SingleFullAreaRGB
- Acq_SingleMediumAreaBayer

- Acq_SingleMediumAreaRGB
The denominators "single" and "dual" in the name of the applet refer to the maximum number of cameras you can connect. For more information, see Choosing the Right Area Scan Acquisition Applet.
Choosing the Right Area Scan Acquisition Applet#
You must choose the right applet for your camera setup. Otherwise, the image received from the camera can't be processed or displayed correctly or camera performance may be reduced significantly.
Which applet is the right one depends on the number of cameras, the number of channels per camera, and the desired ROI step size.
The ROI step size depends on the parallelism of the image preprocessing and therefore varies by camera and frame grabber.

Using Acquisition Applets#
Find here general information about using the applets with the Framegrabber SDK: Acquisition Applets.
Installing Applets#
Before you can use a specific applet on your frame grabber, you must install it on the frame grabber. Instructions for installing the applets are available at Managing Applets (microDiagnostics).
Adding an Applet Manually#
To add an applet you received as *.dll file (and not in form of an installer) to your host file system:
- Get the applet file (*.dll) you have received.
- Copy this file into the following directory: <Framegrabber SDK directory>/Dll/<Frame grabber model>
Now you can use the new applet.
Testing Image Acquisition#
Before you start using an applet in your own software (via API), you might want to test the system set-up or an individual applet (and its parametrization options).
For this purpose, you are provided with the tool microDisplay X that has been installed on your computer as part of the Framegrabber SDK environment. For instructions how to load and test your applet, see Configuring the Applet (microDisplay X).
Saving Applet Configuration#
After you have configured your applet (in microDisplay X or via Framegrabber API), you can save your configuration. For more information, see Other Tasks (microDisplay X).
