imaFlex CXP-12 Quad#
To install the imaFlex CXP-12 Quad in your host computer, plug it into a PCIe Gen. 3.0 x8 slot or higher. The following image shows an imaFlex CXP-12 Quad with two cameras connected to it:
Image Processing#
The frame grabber is fully programmable by VisualApplets. You can design your own image processing application tuned to your specific needs. Basler offers consultancy support, VisualApplets trainings and of course Basler can also implement for you your specific application.
For information on how to write your own applets, see the VisualApplets documentation.
Production Line Integration#
For integration into a production line, imaFlex CXP-12 Quad 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 imaFlex CXP-12 Quad frame grabbers, and/or
- Synchronize connected devices.
Software Programming and Configuration Interface#
imaFlex CXP-12 Quad offers an easy-to-use API. The Framegrabber API allows to integrate the frame grabber into any image processing application. You can use the Framegrabber API to write code in the following languages:
- 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.

信息
PCIe 总线数据吞吐量取决于主板、芯片组以及主机的 BIOS 配置。安装的 PCIe 板卡数量也会影响吞吐量，例如 PCIe x8 连接器可能仅支持 x4 性能。请务必仔细检查主板手册以确保符合要求。
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).
The socket is located directly on the slot bracket:
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
信息
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 Configuring the Physical Properties of Trigger Signals with the gpioTool.
Pin Layout of the Front GPIO Connector#
信息
The front GPIO connector is provided in form of a MOLEX 83612-9020 connector. For this connector, a matching, ready-made MOLEX D-Sub cable is available (MOLEX 083422-9018).

If you are going to use multiple imaFlex CXP-12 Quad boards in one host computer, make sure you have one PCIe Gen. 3.0 x8 slot or higher per board available in the host computer. For more information, see Using Multiple Boards in one Host.
采集小程序#
To ensure optimum use of system resources, not all image acquisition and processing features designed for imaFlex CXP-12 Quad are loaded onto imaFlex CXP-12 Quad 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.
Typically, an applet supports a specific camera interface standard and topology, specific image acquisition features, and possibly specific image (pre-)processing features. 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.
There are three kinds of applets: acquisition applets (*.dll) always delivered by Basler, custom applets (*.hap) developed in VisualApplets either by yourself or by Basler, and Enhanced Applets:
- The Enhanced Applets are a new set of ready-to-use applets, available for imaFlex CXP-12 Quad. Enhanced Applets are the link between AcquisitionApplets and Custom Applets: Enhanced Applets include functions for the acquisition and pre-processing of image and signal data, as well as the processing of system information. They provide the features Binning, Flat-Field Correction (FFC), and PGI Feature Set. In Enhanced Applets (imaFlex CXP-12 Quad) you find an overview of the available Enhanced Applets.
- Refer to Acquisition Applets for imaFlex CXP-12 for more information about the delivered acquisition applets.
- For PDF documentation of the delivered acquisition applets (GenTL and Fglib), see Applets for imaFlex CXP-12 Quad Documentation.
- In addition to the acquisition applets that are included in the delivery, imaFlex CXP-12 Quad can be programmed to fulfill highly specific image processing tasks that are required by a specific application. The programming can be done by Basler, a certified partner, or by yourself using the easy-to-use graphical FPGA programming environment VisualApplets.
