This TOPSCCC embedded Dos system has been developed for industrial use: is fanless, has a robust compact case which protects the device against strikes and vibration and can be mounted in industrial rails and work in a wide temperature range. This embedded DOS systems features Modbus TCP and an efficient 80188 40MHz CPU, with a 265 kB Flash card. The EX9188E3-MTCP embedded DOS system with Ethernet and RS232 features a 2 x RS232; 1 x RS485 and 1 x Ethernet interface. With this module you are able to communicate with up to 3 over Ethernet connected device as easy as if it were a COM-Port in the PC. Because of the Modbus RTU our embedded DOS systems can be perfectly integrated in any existing LAN-network conforming even the most demanding standards
