CoaXPress High-Speed Video

In the rapidly evolving field of machine vision, CoaXPress high-speed video technology has emerged as a transformative force. Offering unmatched data transmission speeds, it is ideally suited for applications that demand swift and efficient image processing. This article explores what CoaXPress is, how it impacts high-speed video, and how KAYA Instruments harnesses this technology to deliver cutting-edge solutions.

What is CoaXPress?

CoaXPress, abbreviated as CXP, is a digital interface standard designed specifically for high-speed image data transmission in machine vision applications. The name combines “coaxial” and “express,” highlighting its ability to deliver faster data rates over coaxial cables compared to traditional standards like Camera Link or GigE Vision. Utilizing 75-ohm coaxial cables as its physical medium, CoaXPress ensures efficient and reliable data transfer over considerable distances.

In a typical CoaXPress setup, a device such as an industrial digital camera transmits data to a host, like a frame grabber in a computer, via one or more coaxial cables. The CoaXPress 2.0 standard supports bit rates up to 12.5 Gbit/s per cable from the device to the host, with no limit on the number of cables used. This scalability means data rates can be increased to meet the demands of specific applications. For example, modern CoaXPress cameras and frame grabbers may use eight cables to achieve a maximum image data rate of approximately 4.8 GB/s, significantly surpassing the 850 MB/s limit of older standards like Camera Link.

Additionally, CoaXPress provides a low-speed uplink channel, operating at up to 41.6 Mbit/s, which is used for device control and triggering. The host can also supply power over the coaxial cable, delivering up to 13 W per cable, simplifying system setup by reducing the need for separate power supplies. Importantly, CoaXPress requires both the device and host to support GenICam, a standardized programming interface that ensures compatibility and ease of integration across different systems.

How Does CoaXPress Impact High-Speed Video?

The advent of CoaXPress high-speed video technology has significantly influenced the capabilities of high-speed imaging systems. Traditional digital interfaces like Camera Link and GigE Vision have limitations in bandwidth and transmission distance, which can hinder performance in applications requiring rapid data acquisition and processing.

CoaXPress overcomes these limitations by offering higher data transfer rates and the ability to maintain signal integrity over longer cable lengths. This is crucial for applications such as industrial inspection, medical imaging, and scientific research, where capturing and processing high-resolution images in real-time is essential.

Compared to other interfaces, CoaXPress provides several advantages that make it ideal for high-speed video applications. Firstly, it offers higher bandwidth, enabling the transmission of high-resolution images at high frame rates. This is essential for capturing fast-moving objects or processes without loss of detail. Secondly, the use of coaxial cables allows for longer transmission distances without degrading signal quality, providing greater flexibility in system design and installation.

Moreover, CoaXPress supports power over cable, which simplifies setup by allowing both data and power transmission through a single cable. This reduces system complexity and potential points of failure. Additionally, CoaXPress delivers low latency, ensuring minimal delay between image capture and processing. This is critical in time-sensitive applications where immediate data analysis is required.

By addressing the shortcomings of previous standards, CoaXPress high-speed video technology enhances the performance, reliability, and efficiency of high-speed imaging systems, making it a preferred choice for modern machine vision applications.
