B+B SmartWorx VLINX ESR Series 1-Port Ethernet Serial Server, DIN, Wide Temperature

Industrial and commercial measurement and control systems often have standalone devices with unused serial ports. SmartWorx ESRx Serial Servers allow you to connect those ports into your existing LAN or WAN, giving you access to more information and the ability to configure, manage and troubleshoot those devices from a control room, office or a distant location via a WAN. Save the cost, time and trouble of carrying a laptop out to devices located in distant, cold, dirty or uncomfortable environments. ESRx Serial Servers are built for industrial environments, featuring an IP30 approved, slim line, DIN rail mountable case. They operate from a range of voltages using AC or DC power, feature terminal block power connectors and even support redundant DC power. An external power source is required. Connect a serial device to the ESRx's serial port and connect the ESRx to your LAN. Your networked computer 'sees' the device over the network as a virtual serial connection. ESRx serial servers support TCP or UDP protocols and allow transmit-to and receive-from multiple IP addresses.
ESRx serial servers can be accessed and configured from any web browser on the LAN/WAN allowing you to remotely manage the software and your serial device and do off-site troubleshooting. Vlinx ESRx Serial Servers provide automatic resumption of the TCP data connection in case of a power failure or loss of an Ethernet connection on either the client or server. Once the Heartbeat connection is established, the server sends a signal to the client every five seconds until communication is reestablished. Without this feature, a device that loses a connection and stops communicating would not be able to reconnect without a person physically attending to the problem. The Heartbeat feature works with virtual COM and TCP direct IP connections.
