IC695NIU001以太网网络接口单元，通常被称为以太网接口（Ethernet Interface），是网络数据连接的端口，它遵循IEEE802.3标准。以太网接口通过物理层和数据链路层实现计算机之间的数据交换，是计算机系统中进行数据传输和共享、网络组网与通信的重要部分。

IC695NIU001 以太网接口的工作原理基于以太网协议，这是一种广泛使用的局域网协议，它定义了物理层和数据链路层的规范。以太网接口通过物理层的传输介质（如双绞线、光纤等）将数据帧传输到目标设备，然后在数据链路层将数据帧解包，提取出目标MAC地址和源MAC地址，然后将数据帧传递给路由器的网络层进行路由。

IC695NIU001 以太网接口通常使用RJ-45接头连接计算机和局域网（LAN）或广域网（WAN）。在物理层，以太网接口使用双绞线等传输介质将数字信号转换为模拟信号，并通过电流、电压等方式进行传输。这种分帧的机制可以确保数据的可靠传输和接收。以太网接口支持点对点（point-to-point）和多点（multipoint）的连接方式，能够灵活地适应不同规模和需求的网络环境。

The IC695NIU001 Ethernet network Interface unit, commonly referred to as an Ethernet Interface, is a network data connection port that complies with the IEEE802.3 standard. Ethernet interface realizes data exchange between computers through physical layer and data link layer, and is an important part of data transmission and sharing, network networking and communication in computer system.

The working principle of the IC695NIU001 Ethernet interface is based on the Ethernet protocol, a widely used LAN protocol that defines specifications for the physical layer and the data link layer. The Ethernet interface transmits data frames to the target device through the transmission medium (such as twisted pair or optical fiber) at the physical layer, unpacks the data frames at the data link layer, extracts the target MAC address and source MAC address, and then transmits the data frames to the network layer of the router for routing.

The IC695NIU001 Ethernet interface typically uses an RJ-45 connector to connect a computer to a local area network (LAN) or wide area network (WAN). At the physical layer, the Ethernet interface uses twisted pair and other transmission media to convert digital signals to analog signals, and transmits them through current and voltage. This frame splitting mechanism can ensure the reliable transmission and reception of data. Ethernet interfaces support point-to-point and multipoint connections and can flexibly adapt to network environments of different scales and requirements.
