B+B 4 Port Ethernet Serial Server ESR904

Use the ESR to convert Ethernet to RS232 or convert Ethernet to RS485 to connect PLC's, CNC machines, HMI panels or any other industrial equipment that has an RS232, RS422 or RS485 serial port to the LAN. By installing an ESR Ethernet Serial Server you'll be able to communicate with that equipment from anywhere on the LAN or WAN, eliminating trips out to the plant for programming, diagnostics or data gathering.No software changes required, the ESR Ethernet to RS-232 and RS-485 Converter can be transparent to your existing software making installation quick and easy. Your office or control room PC will show the device as if it had a direct serial communications connection to monitor and fine tune it. You can even troubleshoot the distant device from outside your LAN via the Internet.
