Applying Ethernet communication buses in industry is accompanied usually by adaptation problem of devices equipped only with serial RS ports to Ethernet network requirements. Extra difficulty is variety and differentiation of communication protocols utilized in devices and upper layer systems.

Solution for this kind of problems is converter - hub EKM RS/RJ45. It allows adaptation of protection, control and measurement devices, not equipped with Ethernet port, to requirements of upper layer systems, based on TCP standard.

Applying EKM RS/RJ45 besides of hardware advantages allows utilization of many communication protocols (e.g. Modbus RTU, ASCII, Modbus IP, DNP 3.0. and others) and even writing own or ordering dedicated protocols.
