March 28, 2002 – Ascendant Technologies Inc. and Enterasys Networks Inc. (NYSE: ETS), a leader in enterprise networking solutions, today announced WireFreeDNC™, the manufacturing industry’s first integrated single-port wireless solution for shop floor communications. WireFreeDNC increases mobility and access to network-based resources in manufacturing environments by integrating Enterasys' RoamAbout wireless LAN product with Ascendant’s eXtremeDNC(tm) communication software. The combined solution seamlessly connects CNC equipment directly to an engineering production network to increase productivity.

“The manufacturing environment places unique demands on a communications infrastructure,” said Mads Lillelund, chief marketing officer, Enterasys Networks. “WireFreeDNC is the first solution of its kind to enhance mobile shop floor communications and deliver increased efficiencies. We are delighted to work with Ascendant to develop technologies that answer the business needs of our clients.”
WireFreeDNC works by attaching the Enterasys RoamAbout Ethernet Adapter to a machine tool’s serial (RS232) communications port and placing the RoamAbout Access Point anywhere on the user’s wired network. Customising and combining the features of the wireless Ethernet adapter into the software application produces a wire-free connection controlled from within the eXtremeDNC (Distributed/Direct Numerical Control) server application. The application communicates with CNC (Computerized Numerical Control) machines on the production floor to deliver necessary control information to the tool when producing product. WireFreeDNC provides a direct connection to every CNC machine in the facility and eliminates the use of wired or wireless multiport serial hubs and respective RS232 cables for machine tool communications, while simultaneously delivering the highest levels of network security and reliability available.

“WireFreeDNC adds reliability to the classic RS-232 serial connection between computers and CNC machine tools by removing the long runs of RS-232 cable and replacing them with digital wireless TCP/IP connections,” said Roy Mandir, President of Ascendant Technologies.

In addition, the mobile WireFreeDNC solution better accommodates today’s dynamic manufacturing environment where operators continually make changes to CNC machine tools to facilitate just-in-time (JIT) manufacturing. These changes require costly and labour-intensive rewiring and reprogramming. Enabling mobile employees with convenient access to business-critical information, such as scheduling, repairs and technical data, WireFreeDNC enhances user efficiency and productivity. Furthermore, the technology reduces the time and expense associated with moving and installing RS232 cabling for CNC machine tools.


The system conforms to IEEE 802.11b high rate specifications and can communicate up to 250 serial-enabled machines per Access Point, which may be placed anywhere within a manufacturing facility. Adding high-gain antennas on the RoamAbout Access Points enables building-to-building communication and allows connections of up to 10 miles (line of site) from the Access Point.
WireFreeDNC is available immediately from Ascendant Technologies and its respective dealers. For more information on eXtremeDNC communication software, please visit .
