The Association for Advancing Automation (A3) oversees the ongoing development and administration of the standard.
USB Vision Protocols
USB3 Vision is a widely adopted machine vision interface protocol. It offers significant advantages over its predecessor, USB2 Vision. Key benefits include faster data transfer speeds, support for higher-resolution cameras, and improved performance. USB3 Vision is ideal for applications requiring real-time image processing, high-speed data transfer, and compatibility with a wide range of cameras and devices.
USB3 Vision is compatible with the USB-C connector, providing a versatile and future-proof solution. USB-C offers increased durability, reversible plug orientation, and support for higher power delivery. This compatibility ensures that USB3 Vision can easily integrate with modern devices, further enhancing its usability in machine vision applications.
USB2 Vision (Legacy Support)
USB2 Vision, the predecessor to USB3 Vision, is still used in some legacy systems. Although it has a lower data transfer speed and supports lower-resolution cameras compared to USB3 Vision, it continues to provide a reliable solution for specific applications. USB2 Vision remains a viable option for cost-sensitive or less demanding imaging applications where the advantages of USB3 Vision may not be necessary.
GigE Vision Protocols
GigE Vision is a popular machine vision interface protocol that leverages Gigabit Ethernet technology. It provides several advantages, such as long cable lengths, high data transfer rates, and ease of integration with existing networks. GigE Vision is well-suited for a wide range of applications, including those requiring high-resolution cameras, real-time image processing, and robust data transmission.
For even more demanding applications, 10 GigE and 100 GigE protocols offer increased data transfer speeds. These high-speed variants enable support for higher-resolution cameras and faster frame rates, making them ideal for applications in which rapid image acquisition and processing are essential.
Real-time Data Transmission in Industrial Applications
Real-time data transmission is crucial in many industrial machine vision applications, such as quality inspection, automation, and monitoring. GigE Vision protocols offer reliable, low-latency data transmission, enabling real-time processing and decision-making. The ability to transmit data over long distances without signal degradation makes GigE Vision an excellent choice for large-scale industrial installations and applications where cameras must be positioned far from the processing units.

CoaXPress is a high-speed machine vision interface protocol that combines the advantages of coaxial cable technology with high-performance data transmission. This protocol offers several benefits, such as long cable lengths, high data transfer rates, and real-time image processing capabilities. CoaXPress is ideal for demanding applications that require high-resolution cameras, fast frame rates, and low-latency data transmission.
Common use cases for CoaXPress include industrial automation, inspection, and monitoring applications where rapid image acquisition and processing are crucial. The protocol's ability to transmit data over long distances without signal degradation makes it a suitable choice for large-scale installations and applications with challenging environments.
Integration with FPD-Link for Display Applications
CoaXPress can be integrated with FPD-Link, a high-speed digital video interface protocol commonly used in display applications. This integration allows CoaXPress to provide high-speed data transmission for a wide range of imaging and display applications, ensuring optimal performance and compatibility with various devices and systems. Combining CoaXPress and FPD-Link enables machine vision systems to deliver high-quality images and video for both processing and display purposes, offering a versatile solution for today's demanding imaging applications.
Choosing the Right Protocol
Factors to Consider When Selecting a Machine Vision Interface Protocol
Selecting the right machine vision interface protocol is essential for optimal system performance and ease of integration. Several factors should be considered when choosing a protocol, including camera resolution and frame rate, data transfer requirements, and compatibility with existing systems.
Higher resolution cameras and faster frame rates often require higher data transfer rates, which may necessitate the selection of a more advanced protocol. Data transfer requirements vary depending on the application, with some demanding real-time processing and low-latency transmission. Integration with existing systems is also a critical factor, as it ensures that the chosen protocol is compatible with current hardware and software components.
