Buttons, Switches and LEDs
The board includes 2 buttons, 3 DIP switches, one Reset button that generates a
hardware reset signal, 3 software-defined LEDs (green, yellow and red) and a LED
indicating powering the board from the USB. Any of onboard buttons, DIP switches
and LEDs can be controlled by an embedded application running on a ZigBit.
For instance, the status of any DIP switch will be ignored when running SerialNet (see
Section 6). DIP switches can be tested when running the Hardware Test application
(see Section 4.7).
External Antenna
Among the ATZB-EVB (MeshBean) boards delivered with ZDK, one particular board
is equipped with SMA connector to attach an external antenna. The specifications of
external antenna supplied with the Development Kit are presented below in Table .

WiMo, swivel antenna (1/2
wave antenna) with SMA
connector, frequency range
2.35-2.5 GHz
IMPORTANT NOTE:
Only the Non-RP SMA Connector antennas can be used in
combination with MeshBean boards equipped with an SMA connector!
Attach the external antenna through SMA connector before using the board. Match
the antenna's male coaxial thread with the connector's female thread.
