Cables & Documentation

The CC2520EM in this kit is FCC/IC
certified and complies with ETSI/R&TTE
over temperature from 0 to +35°C.

The antenna, W1010 from Pulse, is a ¼
wave dipole antenna with 2 dBi gain.

FCC/IC Regulatory Compliance
FCC Part 15 Class A Compliant
IC ICES-003 Class A Compliant

2. Assemble the Boards

Insert the MSP430 sandwich boards
(called CCMSP-EM430F2618) into the
SmartRF05EBs. Connect antennas to both
of the CC2520EM. Make sure the
antennas are firmly attached to the SMA
connector. If not, RF performance may be
reduced. Insert the CC2520EM into the
MSP430 board. Do not use excessive
force when assembling the boards.

Caution! The kit contains ESD sensitive
components. Handle with care to prevent
permanent damage. To minimize risk of
injury, avoid touching components during
operation if symbolized as hot.

3. Power Options

There are several ways of applying power
to the SmartRF05EB;

 USB (5V through USB plug)
 External Power Supply

(requirements below)

 2 x 1.5V AA Non-Rechargeable

Alkaline Batteries

Voltage regulators on the SmartRF05EB
will set the on-board voltage to 3.3V.

External Power Supply1 Requirements:
Nom Voltage: 4 to 20 VDC
Max Current: 1500 mA
Efficiency Level V

Warning! To minimize risk of personal
injury or property damage, never use
rechargeable batteries to power the board.

There should only be one
active power source connected
to the board at any time.

4. Select Power Source

Locate the
power source
header P11
just above the
LCD on the
SmartRF05EB
Connect pins 1 and 2 if you are using
batteries to power the board. Connect pins
2 and 3 if you are using USB or external
power supply.

Once you have
set P11, find
switch P8 just
next to the DC
jack on the
SmartRF05EB.
To power on

the board, flip the switch form “OFF” to

“ON”.

Do not leave the EVM powered when
unattended.

5. Packet Error Rate Tester

When power is turned on, the Packet Error
Rate Test program, which is
preprogrammed on the MSP430, will start
running.

The LCD should display the screen as
shown in the picture above. Press Button 1
to enter the menu.

6. Set Channel

Select a channel between 11 and 26
(2405-2480 MHz). The channel is selected
by pushing the joystick to the right or left.
Confirm the selection by pressing Button 1.

7. Select Transmitter/Receiver

Select transmitter on one of the

SmartRF05EB’s and receiver on the other

by navigating with the joystick. Confirm the
selection by pressing Button 1 on both
devices. The receiver is now ready to
receive packets.

8. Select Output Power

On the transmitter node, selection of TX
output power and burst size (number of
packets to send) is also needed. Select TX
output power by navigating the joystick,
either -4 dBm, 0 dBm or 4 dBm, and
confirm with Button 1.

9. Select Burst Size

Select burst size by navigating the joystick,
either 1000, 10K, 100K or 1M packets.
Confirm the selection with Button 1.

10. PER Test Transmitter

The transmitter is now configured for the
PER test. The PER test is started by
moving the joystick UP. The transmitter will
display the number of packets sent during
the PER test. The PER test is stopped by
moving the joystick UP again.

11. PER Test Receiver

The PER test receiver will display the total
PER (calculated based on the received
sequence numbers), and moving average
RSSI value on the display. It will also
display the number of packets received
during the PER test.

12. Download Your Own SW

In order to program the MSP430 MCU on
the CCMSP-EM430F2618 board the
MSP430 Debug Interface is needed.
Connect the MSP430 debug interface to
JTAG connector P12 on the CCMSP­EM430F2618. Connect the debug interface
to the PC with a USB cable.

Use either MSP430 Flasher, CCS or IAR to
download your code.

13. SmartRF Studio

In order to use SmartRF Studio to control
the CC2520 radio, the CC2520EM should
be connected directly to the
SmartRF05EB.

SmartRF Studio can be downloaded from

www.ti.com/smartrfstudio.
