Digi to Release ZigBee(R) PRO Feature Set on Popular XBee(R) Product Line Deployment of Highly Anticipated ZigBee Technology Enhances Digi's XBee Product Family

Digi International (Nasdaq: DGII) today announced the release of the low power XBee ZB and extended range XBee-PRO(R) ZB ZigBee modules based upon the ZigBee PRO feature set. The ZigBee PRO feature set enables deployment of larger, more stable and interoperable ZigBee networks with advanced features.

The ZigBee PRO feature set provides significant advances in interoperability, node density management, data load management, frequency agility and builds upon the mesh networking and low-power capabilities of prior feature sets. Based on the Ember EM 250 chip and ZNet 3.1 stack, the XBee ZB and XBee-PRO ZB modules will also be capable of over-the-air firmware updates, allowing customers to change settings and features without directly accessing hardware.

"The addition of the latest ZigBee features to the XBee product family elevates our product line to a new level," said Larry Kraft, senior vice president of global sales and marketing, Digi International. "OEMs can now create robust wireless applications with broad interoperability through the use of ZigBee public profiles."

Bob Gohn, vice president of marketing for Ember Corporation added, "Ember is pleased to partner with Digi on the development of this exciting and highly anticipated new product."

As a member of the XBee family, the XBee ZB and XBee-PRO ZB modules share a common electrical interface, form factor, and software interface with other XBee platforms, including 802.15.4, ZNet 2.5, and 900 MHz XSC, allowing OEMs to rapidly change platforms as needed. This extensibility allows OEMs to tailor their RF solution to their application with minimal development. As a member of Digi's Drop-in Networking product offering, the XBee ZB and XBee-PRO ZB modules will plug into products such as gateways that provide XBee to Ethernet, Wi-Fi, and cellular functionality; adapters that provide serial, analog I/O, and digital I/O to XBee functionality; and wall routers that provide network extension functionality.

XBee ZB and XBee-PRO ZB modules will be available for worldwide deployment this May starting at $16.80 in 1,000-piece pricing. Firmware compatible with existing XBee and XBee-PRO ZNet 2.5 hardware is currently available.
