RS232 RS485 RS422 Serial to Ethernet Modbus Converters / Device Servers

In the past two decades, legacy serial communication protocols such as Modbus have merged rapidly with modern TCP/IP communication, yielding benefits including widely available infrastructures and greater distance, reliability, and flexibility. CommFront offers a range of industry-proven, easy-to-use serial to Ethernet converters and device servers, both hardware and software types. The applications of our serial to Ethernet converters include acting as a device server or a Modbus RTU/ASCII to Modbus TCP protocol converter; extending serial ( RS232 / RS485 / RS422 / TTL) communication distance over Ethernet network; controlling serial devices from remote Modbus TCP software or Modbus RTU master via Ethernet network; making a wide variety of M2M communication applications possible by enabling client access independent of any operating system or proprietary protocol; and converting conventional serial data network into TCP/IP network, etc.
