Product details
The D-Link DE-855 is a transceiver converter that bridges Thin Ethernet (10BASE2) coaxial networks with AUI (Attachment Unit Interface) ports. It allows legacy coaxial cabling to connect to modern network interfaces that utilize the AUI standard. This device is designed for specific, older network integration scenarios.

Description
The D-Link DE-855 is a legacy network component designed to facilitate the interconnection between older 10BASE2 Thin Ethernet coaxial networks and devices equipped with an AUI (Attachment Unit Interface) port. In the era of early Ethernet deployments, coaxial cable was a common medium for network connectivity, and AUI ports were standard on network interface cards and hubs. The DE-855 acts as a bridge, translating the signals between these two distinct physical layer interfaces. This transceiver converter features a BNC connector for plugging into the coaxial cable used in 10BASE2 networks. On the other side, it provides a 15-pin D-sub (DB-15) AUI connector, which would then connect via an AUI cable to the network device. The DE-855 operates at a speed of 10 Mbps, consistent with the 10BASE2 standard, and handles the necessary signal conversion to allow data to flow between the two network types. While 10BASE2 and AUI interfaces are largely obsolete in modern networking, devices like the DE-855 were essential for integrating existing coaxial infrastructure with newer equipment or for maintaining legacy systems. Its primary function is to enable communication by adapting the electrical and physical characteristics of the coaxial cable medium to the requirements of the AUI interface, bridging the gap for specific, older network setups.
