Smallest Z-Wave USB stick in the market  +++ Supports Security S2 and Smart Start +++ Firmware for static controller or bridge (Z/IP) +++ Allows changing frequencies with software

This USB Stick connects a PC or any other computing platform with USB interface to a wireless Z-Wave network. A controller software compatible to the Sigma Designs Serial API is required to use the functions of the device. This software plus this UZB realise a static controller to manage and use Z-Wave devices of various vendors. This stick works with all certified Z-Wave devices regardless of its vendor or date of origin. The Sigma Designs Serial API specification is available to all owners of a Sigma Designs Z-Wave SDK.

The device implements a virtual serial interface used by the Z-Wave application. Linux and Mac OSX has a built in device driver for the stick and will create a new device named like /dev/cu.usbmodemfa131 (OSX) or /dev/ttyACM0 (Linux). Windows enumerates a new COM device but may require a device driver uzb.inf available below.

Compared to the standard firmware design used by almost all Z-Wave USB Sticks and other Z-Wave Host Interface hardware, the UZB firmware offers several extensions and enhancements:

  • Backup and recovery function including network topology
  • Optimised transmitting queue handling to speed up transmitting process
  • Firmware update from the OS level in the field
  • Trusted Platform module applying strong encryption
  • Extended Wakeup Notification
  • Handling to extend battery life time of battery operated devices in the network

The UZB comes in three different versions depending on the transmitting frequency used:

  • ZMEEUZB: Version for all frequencies around 868 MHz (like EU, Russia, India, default is EU).
  • ZMEAUZB: Version for all frequencies around 921 MHz (like Australia, Korea, Brasil, default is Australia)
  • ZMEUUZB: Version for all frequencies around 908 MHz (like USA; Israel, default is USA)

Please check what frequency range you need. You may need to change the frequency within the frequency group using a shell script tool or Z-Way. For more information about technical data an the different operating frequencies please refer to the UZB manual.
