SAN JOSE, Calif. – April 3, 2007 – MaxStream®, a Digi International® brand (NASDAQ:DGII), announced today the addition of the XBee™ Series 2 ZigBee® module. Leading the market in easy-to-use embedded ZigBee technology, MaxStream further strengthens its leadership position by adding a module that includes full mesh networking capabilities.

In addition to full self-discovery/self-healing mesh networking, the 2.4 GHz XBee Series 2 supports coordinators, routers and end devices, as well as low power sleep modes. Based on the Ember EM250™ system-on-chip, the FCC-pending XBee Series 2 features a 16-bit microprocessor, 128kb Flash memory, and four different antenna options (chip antenna, wire whip, U.FL connector, RPSMA connector).
