CC112x Evaluation Module Kit Quick Start Guide
Opening the Box and Running the Packet Error Rate Test
1. Kit Contents
2. How to use the Modules
3. Plug the EM into the TrxEB
The CC112xEM boards can be plugged into
several development boards from Texas
Instruments. Most notably, you can use the
SmartRF Transceiver EB, which is included in
the CC1120DK. 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.
2 x CC1120 or CC1121 Evaluation Modules
2 x Antennas (type depending on frequency)
The EMK is an add-on kit to supplement the
CC1120DK with evaluation boards supporting
additional frequency bands. This document
covers the CC1120EMK and CC1121EMK.
Antenna types:
955 & 868-915 MHz:
420-470 MHz:
169 MHz:
It is also possible to connect the EM to other TI
development boards with the appropriate
connectors or to the basic “SoC Battery Board”.
The latter can be used as a carrier board for the
EM to simplify the connection to other boards
with a microcontroller. See:
http://www.ti.com/tool/soc-bb
This guide will show how to use the modules
together with SmartRF Transceiver EB (TrxEB).
Pulse W5017
Pulse SPWH24433TI
Pulse SPHL24169TI
Insert a CC112xEM into the TrxEB. Do not use
excessive force on the EM. Remember to mount
the antenna.
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.
The hardware in this kit is tested and complies with
ETSI/R&TTE over temperature from 0 to +35°C. The
W5017 whip antenna from Pulse has a gain of 2 dBi
4. Select Board Mode
5. Power Options
Use the switches S1 and S2 to select the
operating mode of the board. For the sake of this
quick start guide, please select “Enable” and
“UART”. This configuration will make it possible
to communicate directly with the MSP430 over a
virtual COM port on the PC.
There are several ways of applying power to the
TrxEB.

6. Select Power Source
2 x 1.5 V AA batteries
USB
External Power Supply
MSP430 Debugger
For the batteries and USB, there are voltage
regulators on the TrxEB that will set the on-board
voltage to 3.3 V.
Warning! To minimize risk of injury or property
damage, never use rechargeable batteries to
power the board. Always select a power source
that is suitably rated for use with this EVM, not
exceeding 3.6 VDC, with a current output
rating between 0 and 500 mA.
Depending on the power source, make sure you
connect jumpers to the appropriate pins on the
“Power Source” header. For instance, if you use
batteries, use a jumper to short-circuit pin 1 and
2 on the header. See back side of board for
explanation of the jumpers.
Note that there should only be one active
power source at any one time. Do not
leave the EVM powered when unattended.
7. Welcome Screen
8. Packet Error Rate Test
9. Select Test Mode
Turn on power with the Main Power switch. You
should now see the Texas Instruments logo and
a short description of the buttons on the LCD.
Pushing any of the five buttons on the board will
take you to the main menu.
Select the PER (Packet Error Rate) test by
highlighting the selection using the up/down
buttons. Confirm your selection by pressing
Enter (right button).
The PER test can be run is several modes. Easy
Mode sets up a one-way test and uses default
settings. This test is convenient for practical
range testing.
The other test modes are described in the
“Software Examples for CC112x, CC11xL and
CC1101 User’s Guide”.
NB! If you don’t see anything on the screen
make sure the mode switches are in the
correct positions (see step 4 above).

10. Select Frequency
11. Select Mode
12. Establish Link
One of the boards must operate as the slave
(transmitter) and the other as master (receiver).
Select Slave on one board…
The slave node will now wait for a configuration
package from the Master. The configuration
contains the parameters used for the PER test.
…and Master on the other board.
The configuration package will be sent when you
select “link devices” on the master node.
13. Link Established
14. Start the Receiver (master)
15. PER Test Results
When the initial linking has completed, the slave
node will start the test by continuously
transmitting packets to the master.
On the master node, you can select the number
of packets you want to receive in order to
calculate the packet error.
The master will display a window that plots the
received signal strength (RSSI) for each packet.
When selecting “Start PER Test”, the master
(receiver) will begin to count the number of
received packets and provide some statistics.
Press the “Up” button to go to the detailed
statistical window.
17. Troubleshooting
18. References
It you are experiencing problems with this test,
please check the following:
Please visit www.ti.com and
Select which frequency to use for the test. Make
sure that the evaluation modules you have
match the selected frequency.
16. PER Test Results
The statistics window will show the error rate
based on the number of lost or erroneous
packets divided by the total number of packets
that should have been received.

Nothing
is shown
in the display!
Unfortunately, the first series of TrxEB uses
a connector that doesn’t fit exactly to the pins
of the LCD. It should be sufficient to tilt the
LCD slightly to get a snug fit with the
connector.
Please visit the kit web page and check for
updated SW and documentation. Updated
SW can be downloaded to the device using
IAR EW430 or SmartRF Flash Programmer.
If you get poor PER results at short
distances, try to move the transmitter and
receiver further apart. The CC1120/CC1121
receiver may experience saturation if it is too
close to the other CC1120/CC1121
transmitting at full output power.
