The Black Box <b>LES301A</b> is an LES300 Series industrial serial device server that provides remote access to serial devices across your LAN/WAN. Use your ethernet network to reliably access a remote RS-232 or RS-422/-485 industrial device from a remote workstation.</p><p>This 1-Port 10/100 device server gives you a cost-effective gateway for TCP/IP ethernet and serial signal communications, enabling nearly any serial device to be connected to a new or existing ethernet network. It does this by encapsulating serial data and transporting it over ethernet, communicating full-duplex and transmitting bidirectional data transparently between the serial port and a network.</p><p>Plus, it's easy to configure. You can do this remotely over the ethernet link using Telnet, a web browser link, a serial console, or another Windows utility. This unit comes with virtual communications software allowing you to use an existing Windows based application to access a serial device by mapping the virtual COM port to a remote serial server over ethernet.</p><p>In addition, the device server supports TCP server, TCP client, and UDP modes of communication, and serial tunneling, which you can use to send data between two serial devices via the TCP/IP link instead of RS-232, -485, or -422 connections. Link a touchscreen to a distant PLC over the ethernet network, for instance. Ideal for any manufacturing, process engineering, or automation application, the 1-Port 10/100 device server, RS-232/422/485 can also be used to communicate with a bar-code scanner, PLC, electronic Kanban inventory management device, and similar equipment on the factory floor.</p>
