The NI PXIe-1422 is a high-performance digital image acquisition device. Here is its detailed information in English:
- Manufacturer: National Instruments.
- Product Family: PXIe series.
- Compatibility: Suitable for PXIe chassis, and can be used in combination with other PXIe modules to form a complete measurement and control system.
- High-resolution Image Acquisition: Supports 8, 10, 12, and 16-bit (grayscale or color) digital image acquisition. It can acquire high-quality images, which is suitable for applications requiring high-precision image processing, such as industrial inspection, scientific research imaging, etc.
- High-speed Acquisition Rate: With a 40 MHz pixel clock rate, it can achieve an acquisition rate of up to 80 MB/s. This allows for fast capture of dynamic images, ensuring that transient image information is not missed.
- Camera Compatibility: There are two versions available, one is compatible with RS-422 signals from digital cameras, and the other is compatible with LVDS camera signals. It can connect to a wide range of digital cameras from different manufacturers, providing users with more choices.
- Onboard Memory: It is equipped with 16 MB of onboard memory. This memory can buffer images on the board, which is beneficial for large-image capture and sustained real-time throughput, and can reduce the pressure on the system bus.
- Flexible Trigger and Control Functions: It has 4 programmable digital I/O lines for triggering and control. The trigger sense can be TTL, and the trigger level is programmable (rising or falling). In addition, it also supports selectable pixel clock sense (TTL or differential), enable sense (TTL or differential), and master clock drive (TTL or differential), etc., which can meet various complex application scenarios that require precise timing and triggering.
- Data Formatting Function: It has a multiple-tap data formatter function. For digital cameras that transfer multiple channels or taps of data simultaneously to increase the frame rate, the multiple-tap data formatting circuitry on the PXIe-1422 can reorder the data from up to two 8-bit taps, making the data more conducive to subsequent processing.
- Lookup Table Function: It uses a 64 kb×16-bit lookup table (LUT), which can be used for two 256 b×8-bit LUT tasks or one 64 kb×16-bit lookup table. Users can configure this LUT to perform common imaging operations, such as contrast enhancement, data inversion, gamma adjustment, or other nonlinear transfer functions, to meet different image processing requirements.
- Pixel Clock Frequency Range: 500 kHz to 40 MHz (±0.5% of the selected frequency).
- Data Path: 16 bits.
- Connector: 100-pin SCSI - type connector.
- Power Requirements: It needs to obtain power from the PXIe chassis, and the specific power consumption parameters are determined according to the actual working conditions.
- Electromagnetic Compatibility: Complies with relevant electromagnetic compatibility standards, such as CE, C - tick, and FCC Part 15 (Class A) compliant electrical emissions (the specific standards may vary depending on different models and application scenarios).
- Driver Software: It is equipped with NI - IMAQ driver software. This driver software provides a unified interface for the PXIe-1422, allowing users to easily control the device in different application development environments.
- Application Development Environments: It is compatible with common application development environments such as LabVIEW, LabWindows/CVI, and Measurement Studio. Users can use these development environments to write custom image acquisition and processing applications according to their own needs.
- Configuration Utility: Users can use the Measurement & Automation Explorer (MAX) included in the NI Vision Acquisition Software to configure the PXIe-1422. MAX is an interactive tool that can be used to set the region of interest, camera control parameters, etc., making the device configuration more convenient and intuitive.
