Image Processing#

Image processing functionality is available on request. If you are interested, contact Basler Support.

Production Line Integration#

For integration into a production line, marathon ACX-QP offers multiple general purpose inputs and outputs. 4 to 20 of the GPIOs (depending on the hardware add-ons used) are galvanically isolated.

These GPIOs enable you to do the following:

  • Control peripheral devices by sending trigger signals, e.g. lighting signals and cameras signals.
  • Receive various trigger signals from peripheral devices, e.g., shaft encoders and light barriers.
  • Synchronize multiple marathon ACX-QP frame grabbers.
  • Synchronize connected devices.

  • C/C++
  • C# (wrapper available)
  • Python (wrapper available)

For more information about the Framegrabber API, see the Framegrabber API documentation.

Alternatively, you can use Basler's GenTL Interface to develop your application in form of a GenTL consumer. For more information about the Basler GenTL Interface, see GenTL Interface documentation.

Info

The PCIe bus data throughput depends on the mainboard, the chip set, and the BIOS configuration of the host computer. The number of installed PCIe boards also affects the throughput, e.g. a PCIe x8 connector may support only x4 performance. Always check the mainboard manual thoroughly to be sure.

The Front GPIO Connector#

The front GPIO connector covers the basic trigger setup of your frame grabber. Its trigger connector allows you to control peripheral devices (PLC) and to synchronize multiple marathon ACX-QP boards.

The socket is located directly on the slot bracket:

The Front GPIO Connector

In default configuration, the trigger connector of the front GPIO connector offers:

  • 3 differential input signals or 2 differential and 1 single-ended input signal in pull-up mode
  • 2 TTL output signals

Info

You can configure the pin assignment of the front GPIO connector to provide different input signals, e.g.:

  • Pull-down
  • 4 single-ended signals (and no differential signals).

To change the GPIO configuration, use the command line tool installed with the Framegrabber SDK.

For more information, see Input Configuration and gpiotool.

Extra Voltage IN/GND for Galvanically Isolated Circuit#

All General Purpose Inputs (GPIs) of the front GPIO connector are galvanically isolated. The incoming signals are transferred to the frame grabber via digital isolators. This way, the frame grabber is securely protected against high incoming voltages.

However, to operate the internal GPI circuits, you must connect a voltage source and ground: On pin 10, you apply the voltage (GPI voltage IN) that serves as operating voltage for the internal operational amplifiers. On pin 15, you connect the according ground (GPI GND).

Supply Voltage Required

The marathon ACX-QP trigger system needs to get supply voltage on the GPI Voltage IN pin (pin 10). If you want to connect devices that have no PWR pin, you must provide the power supply to the GPI Voltage IN pin (pin 10) from an external source.

Possible Topologies#

You can operate marathon ACX-QP as follows:

Number of Cameras Number of Camera Ports Number of Frame Grabber Ports Mode Topology
1 4 4 Bayer Pattern One Camera, Four Ports, Bayer Pattern
1 4 4 Grayscale One Camera, Four Ports, Grayscale
1 4 4 RGB One Camera, Four Ports, RGB
2 2 4 Bayer Pattern Two Cameras, Two Ports Each, Bayer Pattern
2 2 4 Grayscale Two Cameras, Two Ports Each, Grayscale
2 2 4 RGB Two Cameras, Two Ports Each, RGB
4 1 4 Bayer Pattern Four Cameras, Four Ports, Bayer Pattern
4 1 4 Grayscale Four Cameras, Four Ports, Grayscale
4 1 4 RGB Four Cameras, Four Ports, RGB

When connected to the computer power supply via the PCIe 6-pin connector, which always provides 12 V, marathon ACX-QP supports Power over CXP (PoCXP).

Info

If you are going to use multiple marathon ACX-QP boards in one host computer, make sure you have one PCIe Gen. 2.0 x4 slot or higher per board available in the host computer. For more information, see the following topics:

To find out which topology you can use with which applet, refer to Choosing the Right Area Scan Applet or Choosing the Right Line Scan Applet.

Acquisition Applets#

To ensure optimum use of system resources, not all image acquisition and processing features designed for marathon ACX-QP are loaded onto marathon ACX-QP simultaneously.

Instead, Basler provides various compilations of specific image acquisition and processing features that are combined to meet the requirements of a specific application field. These compilations are called applets, since they work like apps on mobile devices.

Typically, an applet supports a specific camera interface standard and topology, specific image acquisition features, and possibly specific image (pre-)processing features.

Applets come in .dll files.

Refer to Acquisition Applets for marathon ACX-QP for more detailed information about applets and their dependency on the topology used.
