WiPort™-485 Data Sheet General Description The WiPort-485 is the most compact, integrated solution available to add 802.11b wireless networking to any device with an RS-422 or RS-485 serial interface. Using our highly integrated hardware and software platform, you will add to your bottom line by significantly reducing product development time, risk, and cost. The WiPort-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 WiPort-485 offers the highest level of integration available in a device server. Within a compact package is a DSTni x86 controller, memory, 802.11b transceiver, a 10/100 Ethernet transceiver, and dual high-speed serial ports. All of this combines to give you a complete networking solution. The WiPort-485 is designed with flexibility to support additional wireless standards without requiring redesign. To enable access to a local network or the Internet, the WiPort-485 integrates a fully developed TCP/IP network stack and OS. The WiPort-485 also includes an embedded web server that can be used to remotely configure, monitor, or troubleshoot the attached device. WiPort-485 serves web pages to a web browser when there is a need to gather information or communicate with networked devices. The WiPort-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 WiPort485 can also be configured locally through its serial port, or remotely over a network using Telnet (password-protected) or a web browser. Flash memory provides for maintenance-free, nonvolatile storage of web pages, and allows future system software upgrades. Hardware & Software Description The WiPort-485 functions independently of a PC, providing a complete hardware and software solution for adding wireless connectivity to your devices. Within a single package this powerful device server comes with an 802.11b wireless connection, a 10/100 Ethernet transceiver, a reliable and proven operating system stored in flash memory, an embedded web server, a full TCP/IP protocol stack, and WEP security. Key Features • Complete integrated solution • Supports WLAN or Ethernet connectivity • Serial to 802.11b conversion • RS-422/485 support • Multi-drop RS-485 network support • Stable, field proven TCP/IP protocol suite and web- based application framework • Easy configuration through a web interface • Easy installation of customized web pages • Embedded web server • 11 General Purpose Input/Output (GPIO) pins • 802.11b wireless interface • E-mail alerts • Password protection • Upgradeable firmware via the network or serial port • Dual serial ports • 128 bit WEP encryption The WiPort-485 software runs on a Lantronix DSTni controller which has 256 KB of internal SRAM, and 16 KB of boot ROM. The WiPort-485 communicates to the device through a 3.3V logic level interface. 2 MB of flash memory is included for storing firmware and web pages. A larger memory option is available that includes 4 MB of flash memory, and an additional 1 MB of SRAM. The WiPort-485 runs on a single 3.3V supply, and has a built-in voltage supervisory circuit. The WiPort-485 will connect through a coaxial cable "pigtail" to a panel-mounted external antenna, which makes the electro-mechanical integration very simple.
