Ethernet Assemblies are fully IEEE 802.3 compliant. Modular adapters eliminate the need for conventional, bulky, data communications cabling in RS232/X.21 environments, relying instead on standard UTP wiring schemes. Perfectly suited for moves, adds, and changes, once attached to your hardware, changing out cables is as simple as plugging, and un-plugging an RJ45. DB assemblies are used for many different applications in the telecommunication industry.
