Marathon Sensors Inc. announces the availability of Ethernet connectivity for all current and legacy instrumentation. With this capability, any existing installation can be made fully compatible with Ethernet networking and the most modern data acquisition and supervisory systems. Marathon’s MMInet hub allows users to seamlessly interface multiple instruments to industry-standard IP addresses. These instruments can then be accessed over a virtual serial port on a control computer using a simple driver. Up to 15 MMI-protocol instruments or 247 Modbus instruments can be attached to a single MMInet hub. MMInet is simple to install – just assign IP addresses and wire your RS-485 connections to the hub. The hub is then connected to your LAN and addressed by your SCADA system using a virtual serial-port driver.
