2. How to use the modules
The CC2500EM boards can be plugged into
several development boards from Texas
Instruments. Most notably, you can use the
SmartRF04EB, which is included in the
CC2500DK. This board lets you run a packet
error rate (PER) test, control the device from
SmartRF™ Studio and it can be used as a
development platform.
The board can also be plugged into the SmartRF
TrxEB (included in e.g. CC1120DK and
CC1200DK) and the MSP430 Experimenter’s
Boards.
For prototyping with other microcontrollers, plug
the EM into the SoC Battery Board”
(www.ti.com/tool/soc-bb).
This guide will show how to use the modules
together with SmartRF04EB.
3. Plug EM into SmartRF04EB
Insert a CC2500EM (EM) with an antenna into
the SmartRF04EB (EB). Connect the antenna
firmly to the SMA connector on the EM.
Caution! The kit contains ESD
sensitive components. Handle with care
to prevent permanent damage.
4a. Power: Battery
There are three different ways of applying power
to the EB:
The first method involves using an alkaline non-
rechargeable battery, either a 9V or a 4xAA
battery pack connected to the battery connector
on the bottom side of the board
Warning! To minimize risk of personal injury or
property damage, ONLY use alkaline non-
rechargeable batteries. Never use rechargeable
batteries to power the board.
4b. Power: DC/External
The second method applies DC power using
the DC input jack (right in picture, centre is +,
sleeve is ground), or by connecting a 4-10V
voltage source between the 4-10V and 0V
terminals of the power connector (left in
picture). It is also possible to connect a 3.3V
voltage source between the 3.3V and 0V
terminals. The on-board voltage regulators will
be bypassed in this case.
External Power Supply1 Requirements:
Nom Voltage: 6 VDC
Max Current: 800 mA
Efficiency Level V
4c. Power: USB
The EB can also be powered from the USB bus.
Make sure that the SmartRF Studio software is
installed before connecting the EB to the PC;
otherwise you may experience problems in
installing it later due to driver issues.
Note that if multiple power sources are
connected, the source with the highest voltage
will power the EB. This means that you should
disconnect any attached battery when using a
lab supply or USB power; otherwise the
battery will be drained.
5. Set Power Switch
If a 3.3V source is used as described in 4b
above, the switch should be set to the leftmost
position. For all other cases, the switch should
be set to the rightmost position. This switch can
be used to turn off the EB by switching it to the
opposite position of that used to turn it on
Do not leave the board powered when
unattended.
6. Packet Error Rate Test
When power is applied to the board, the PER test
program will start. You should see the text shown
above on the LCD display on both evaluation
boards.
Press the button marked S1 (lower right corner)
to continue.
7. Set Frequency Band
Select the desired frequency band of operation by
using the joystick. The frequency should match
the evaluation module and antenna you are
using.
Note that the value shown in the display is also
the selected value. There is no need to press a
button to select or activate the selection.

When using an external power supply, make sure it meets the listed requirements in addition to complying with applicable regional product regulatory and
safety certification requirements such as UL, CSA, VDE, CCC, and PSE

8. Set Network ID
Push the joystick down to display the screen
shown above. This lets you set the ID of the node
in case you need to run several PER tests
simultaneously and you have multiple
development kits. Leave this set to 1 for now.
9. Packet Length
Push the joystick down to display the screen
shown above. This lets you set the length of the
packets to be transmitted. The packet length will
affect the measured packet error rate. Push the
joystick left or right to select the packet length you
want to use.
10. Number of Packets
Push the joystick down to display the screen
shown above. This lets you set the number of
packets to be transmitted. Set this to the desired
value using the joystick.
11. Select RF Settings
Push the joystick down to display the screen
shown above. This lets you select preset RF
configurations, including modulation and data rate
Preset 0: 2-FSK, 2.4 kBaud
Preset 1: 2-FSK, 10 kBaud
Preset 2: MSK, 250 kBaud
Preset 3: MSK, 500 kBaud
12. Select Mode
Push the joystick down to display the screen
shown above. Use the joystick to select master
mode. The EB you have configured now will be
the master in the PER test.
13. Configure 2nd EB
Perform steps 3 through 11 on the second EB.
Push the joystick down until you get the display
shown above. Leave this EB in slave mode.
14. Start PER
Push the joystick down on both EBs, and the
screen shown above is displayed. Push the
joystick right on the slave EB first, and then push
the joystick right on the master EB. The PER test
will start when the two nodes have successfully
connected.
15. Run PER Test
The uppermost line of the LCD will show the PER
for packets transmitted from the slave to the
master, while the second line will show the PER
for packets transmitted from the master to the
slave.
The PER test will end when the number of
packets you selected in step 10 is reached or if
100 consecutive packets are lost.
