Lantronix’ XPress-DR and XPress-DR-IAP device servers allow virtually any serial device to be connected to a new or existing Ethernet network. By encapsulating serial data and transporting it over Ethernet, the modules allow virtual serial links to be established over Ethernet. By using these units, limited-distance, point-to-point, direct serial connections can be extended within a plant, throughout a facility, or across a global enterprise.
When used in conjunction with an OPC server, most Windows-based HMI, scada and PC-based control applications have full access to information in the connected device. Existing COM-port based Windows applications can access network-enabled devices using the COM Port Redirector software, which allows the creation of virtual serial ports that can be mapped to the remote device servers over Ethernet and connected to the XPress-DR and XPress-DR-IAP.
The installable communication drivers allow specific support for various industrial communication protocols. With native support for these protocols, devices that previously allowed only one connection can now support multiple connections simultaneously. Flexible configuration options allow the unit to be set up locally using the serial port, or remotely over Ethernet using Telnet or a common web browser. Included Windows-based configuration software simplifies the process of installing communication drivers and configuring them for use with attached devices. Flash memory provides for maintenance-free, non-volatile storage and allows future system upgrades.
Packaged in a rugged DIN-rail mount case and featuring 2000 V galvanic isolation, 1500 V Ethernet isolation, a 0°C to 60°C operating range and a 9–30 V d.c./9–24 V a.c. power input, the devices are suitable for many industrial applications.
