Common interface types for vision controllers include GigE Vision interface, 10GigE interface, SFP+ interface, and USB interface.
GigE Vision interface
The GigE Vision interface was introduced into the field of industrial machine vision in 2006. It is based on the Internet Protocol (IP) standard and transmits video and related control data over Gigabit Ethernet. It supports a bandwidth of 1Gbps and is compatible with a large number of software and hardware devices, which simplifies the network and improves scalability and flexibility. In addition, the GigE Vision interface does not require the use of a Frame Grabber, and most systems use a standard network adapter card that supports GigE/10GigE, which helps reduce system costs.
10GigE interface
The 10GigE interface can transmit image data at speeds of up to 10 Gbps and is suitable for applications that require high-speed data transmission. It supports long-distance operation and can support cables up to 55 meters using Cat 6 and Cat 6e cables, while Cat 6a and Cat 7 cables can support cables up to 100 meters. The 10GigE interface also supports the Precision Time Protocol (IEEE 1588), further enhancing its functionality and reliability.
SFP+ Interface
The SFP+ interface module supports 10 Gbps rates and is suitable for scenarios that require high-speed data transmission. It is based on the fiber optic physical layer of the GigE Vision protocol, supports long-distance transmission (up to 10 kilometers), and has extremely low transmission noise, can remain stable over long distances, and has high immunity to external noise sources. The SFP+ system can be equipped with any appropriate type of transceiver to support functions such as multiple video streams, PTP, block data, etc.
USB Interface
Vision controllers are usually equipped with multiple USB interfaces, including USB2.0 and USB3.0 interfaces. These interfaces are used to connect external devices such as cameras, storage devices, etc. For example, some vision controllers may be equipped with 4 USB2.0 interfaces and 4 USB3.0 interfaces, as well as 1 built-in USB2.0 interface to meet different connection requirements.
