The wireless version of the XPress DR+ (XPress DR+W) provides serial-to-wireless
network connectivity as an alternative to wired Ethernet connectivity. The wireless unit
uses IP protocol (TCP for connection-oriented stream applications and UDP for datagram
applications), enabling virtually any serial device or equipment to be remotely accessed,
controlled, monitored, or shared on an 802.11b/g wireless network. The XPress DR+W
provides a fully integrated solution that combines an operating system, embedded Web
server, full TCP/IP protocol stack with an 802.11b/g transceiver supporting WEP and
WPA security.
Application Examples
The XPress DR+W has an 802.11b/g transceiver in addition to its serial and Ethernet
ports. Each serial port is connected to the serial communication port of a device. The
wireless transceiver connects to another wireless device or to an Access Point (AP). This
section includes typical scenarios for using the XPress DR+W.
