EDS-2005-EL Overview

Introduction

The SC10E4I MK functions as a high-performance protocol converter, translating data packets between Modbus RTU and Modbus TCP. It features four versatile serial ports that automatically detect RS-232, RS-422, or RS-485 interfaces, allowing for flexible connection to a wide array of field devices. At its core, the gateway is powered by an MT7688AN 580 MHz MIPS CPU with 128MB of DDR2 RAM, running on the stable OpenWrt Linux operating system. This processing power enables the device to support up to eight Modbus TCP masters—each managing 32 simultaneous requests—while also supporting eight TCP slaves on each of its four RTU ports, ensuring high-throughput, bi-directional data conversion in complex applications.

This document details the key features, technical specifications, and ordering information for the SC10E4I MK, highlighting the specific capabilities that make it an ideal solution for industrial network integration.
