Network All Your Industrial Equipment – Quickly and Easily!

For demanding factory applications, Lantronix introduces the XPress-DR+ industrial device server. The XPress-DR+ enables users to remotely configure, monitor and control PLCs, drives, motion controllers, power equipment, barcode scanners and other serial devices from anywhere over the Net.

A versatile, powerful tool for remote management of automation and assembly/packaging equipment at manufacturing sites, automated distribution centers, refinery plants – or any industrial setting – it provides complete access and control of virtually any type of equipment with a serial port!

Extending Network Connectivity with SwitchPort+

Supporting two serial ports and two 10/100 Ethernet ports, the XPress-DR+ features patent-pending SwitchPort+ technology which enables multiple industrial serial devices to be daisy chained (cascaded) from a single network backbone connection. SwitchPort+ combines Lantronix advanced device server technology with Ethernet switching technology to provide a robust and reliable method for networking equipment. Saves time and money by avoiding unnecessary cable runs and eliminates serial cable distance limitations.

Standards Based Communications

Using an open Ethernet architecture as a standard for device communication provides the flexibility to communicate to virtually any type of industrial equipment. Additionally it enables new equipment to be quickly and easily incorporated into existing network system designs.

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 Lantronix Com Port Redirector. This specialized software creates virtual serial ports, which are mapped to the XPress-DR+ over Ethernet.

Thrives in the Industrial Environment

The XPress-DR+ meets the demanding, complex industrial environment head on. Packaged in a rugged DIN-rail mount case, its equipped with isolated serial and Ethernet ports and screw terminal connectors for serial and power. It supports industrial protocols such as Modbus TCP, Modbus ASCII, Modbus RTU and DF1, and is FM-approved for hazardous locations Class 1, Div. 2.

  – 15KV serial ESD protection and 2.5KV Ethernet isolation protects circuitry from overcurrent conditions
  – Wide -40°– 70°C operational temperature range
  – 9-30 VDC and 9-24 VAC power input options

Configuration Flexibility

Flexible configuration options allow the unit to be set up locally using the serial port, or remotely over Ethernet using Telnet or browser. The included DeviceInstaller software simplifies the process of installing industrial protocols and configuring them for use with attached devices. The CPUs flash memory provides maintenance-free, non-volatile storage and easily accommodates future system upgrades. Complete with an auto MDI/MDIX Ethernet interface, the XPress- DR+ is a powerful device communication solution thats perfect for your most demanding industrial applications.
