happens, the status bar at the bottom of the utility window will show "Cannot

cycle power on the Evaluation unit with the black power switch on the board
and try the operation again.
24. There is a second utility available called EvkUtilityLite that removes the Data
Terminal functionality for those who prefer to use hyperterminal or some oth-

pong" mode by turning on DIP Switch 11, you can see the statistics change as
the radios exchange their random data.
Next Steps
You can connect your microcontroller circuitry to the AW2400mSPI without unsol-
dering it from the Evaluation Board by attaching your wiring to the probe points and
leaving the USB disconnected. Use DIP Switch 2 to control whether UART (off) or SPI
