The DSTni-XPress DR Device Server allows most any serial device to be connected to a new or existing Ethernet network. By encapsulating serial data and transporting it over Ethernet, the DSTni-XPress DR allows virtual serial links to be established over Ethernet. By using this unit, limited distance, point-to-point, direct serial connections can now be extended within the plant, throughout the facility or across the 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 our redirector software. Redirector software allows the creation of virtual serial ports, which can be mapped to remote Device Servers over Ethernet with the DSTni-XPress DR-IAP version.

The IAP installable communication drivers allow specific support for most 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 setup 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 in 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 isolation, a wide 0 to 60°C operating range, and a 9-30VDC / 9-24VAC power input, the DSTni-XPress DR and DSTni-XPress DR-IAP are ideal for any industrial application.
