Product Information

The XPort™-485 is the most compact, integrated solution available to web-enable any device with an RS-422 or RS-485 serial interface. By simply adding XPort-485 to a product design, device manufacturers cut their design cycle by as much as 80% and are able to offer Ethernet connectivity in record time. The XPort-485 is configurable for either RS-422 4-wire or RS-485 2-wire communication. It supports multi-drop RS-485 networks by providing a logic level serial interface designed to connect directly to an RS-485 transceiver chip. In the RS-485 2- wire mode, one of the PIO pins supplies the necessary transmit enable signal. The XPort-485 offers the highest level of integration available in a device server. Within a compact RJ45 package is a DSTni-EX 186 controller, memory, 10/100 Ethernet transceiver, high-speed serial port, status/diagnostic LEDs, and 3 programmable I/O pins. In the space that is normally consumed by a connector, the XPort-485 provides a complete networking interface. To enable access to a local network or the Internet, the XPort-485 integrates a fully developed TCP/IP network stack and OS. The XPort-485 also includes an embedded web server used to remotely configure, monitor, or troubleshoot the attached device. Where there’s a need for custom user interfaces and a desire to use common and familiar tools, the XPort-485 can serve web pages to a web browser. The XPort-485 becomes a conduit between you and your device over the network or Internet. The Windows™-based configuration software, DeviceInstaller, simplifies installation and setup. The XPort-485 can also be set up locally through its serial port, or remotely over a network using Telnet or a web browser. Flash memory provides for maintenance-free nonvolatile storage of web pages, and allows future system software upgrades. Using our highly integrated hardware and software platform, you will add profit to your bottom line by significantly reducing product development time, risk, and cost.
