Use your Ethernet network to reliably access a remote RS-232 or RS-422/-485 industrial device from a remote workstation. The LES301A 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.
It is 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. Even better, it comes with virtual communications software. Through it, you can use an existing Windows-based application to access a serial device by mapping the virtual COM port to a remote serial server over Ethernet.
The LES301A 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.
