ZigBee™/802.15.4 Application Kit
The ZigBee/802.15.4 Application Kit
combines Digi’s XBee™ RF modem with the popular RCM3720 RabbitCore™ module
along with an easy-to-use interface to help customers build a practical
ZigBee wireless control network. ZigBee paired with the RCM3720 provides a
low-cost, robust wireless infrastructure that allows users to monitor and
control remote devices within a wireless meshed network.
ZigBee is a wireless technology known for
its reliable, low-cost, lower power characteristics, based on the
established IEEE 802.15.4 standard for packet-based, wireless data
transport. Rabbit®’s ZigBee/802.15.4 Application Kit provides all the
tools to integrate a ZigBee wireless module into your Rabbit-based
solutions.
The kit contains three Digi® ZigBee modules
for full application reference. One ZigBee module is connected to an
Ethernet enabled RCM3720 RabbitCore Module. The RCM3720 runs at 22.1 MHz,
and provides 10Base-T Ethernet, 512K Flash, 256K SRAM, 1MB Serial Flash as
on-board memory, and 33 GPIO lines. The other two ZigBee modules are
standalone node devices.
Samples, libraries and firmware helps to
integrate a ZigBee network into a Rabbit-based embedded solution. A
user-configurable interface allows users to set up a network, discover
other similar ZigBee devices, and control LEDs and switches from an RF
Interface board as a node device. The samples illustrate how a user can
connect via the various topologies such as point-to-point,
point-to-multipoint, and mesh. The kit serves as a template for countless
wireless applications where low power and low data rates are required.
Rabbit and Digi Teamwork
Rabbit Semiconductor and Digi are teaming up to supply embedded control
and wireless solutions for customers to develop a ZigBee wireless control
system. Digi’s wireless modems are easy-to-use and provide reliable
delivery of critical data between devices. The flexibility of the XBee/XBee-PRO™
RF Modules creates the perfect fusion of range, power-conservation,
performance and networking features to ensure accurate and reliable RF
communications.
