Troubleshooting
It does not work
•
Make sure that either a jumper or an amperemeter is connected between the IOI and
II terminals and the IIC and IOC terminals on the power connector.
•
Make sure that the power supply is connected to the correct pins on the power
connector.
•
Make sure that a jumper is connected on CC2420EM.
•
Is the supply voltage correctly polarized? If not, the protection diode will prevent any
current from flowing. + and – are indicated on the PCB. On the DC jack, the tip is +
and the ring is –.
•
Please note that the CC2400EB must be connected to a PC for proper operation. The
FPGA and microcontroller are RAM-based, and firmware must be loaded from a PC
when power is applied to the board.
•
If the USB driver is loaded correctly, you should see the LEDs on the CC2400EB
flash. The LEDs will stop flashing when one of the buttons on the CC2400EB is
pressed or when SmartRF
®
Studio is started.
SmartRF
®
Studio does not recognize the CC2400EB
•
Make sure that you have installed SmartRF
®
Studio using the installation program.
•
Make sure that the USB port on your computer is installed correctly (try another USB
device with the same port). Also note that USB only works correctly with Windows 98,
ME, 2000, XP or newer.
•
Please note that SmartRF
®
Studio can only communicate with the CC2400EB via the
USB port. The serial port cannot be used to communicate with the CC2400EB.
