How to use the Modules
The CC112
x
EM 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 f
rom
SmartRF™Studio and it can be used as
a
development platform.
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
E
M to simplify the
connection to other boards
with a microcontroller. See
:

This guide will show how to use the modules
together with SmartRF Transceiver EB (TrxEB).
3. Plug
the
EM into
the
Trx
EB
Insert a CC11
2x
EM into
the
TrxEB
. The
connectors will only fit in one position so that the
EM cannot be inserted the wrong way. Do not
use excessive
force
on
the EM. Remem
ber to
mount the antenna
.
Caution!
The kit contains ESD sensi
tive
components. Handle with care to
prevent permanent damage. To
minimize risk of injury, avoid touching
components during operation if
symbolized as hot.
4. Select Board Mode
Use the switches S1 and S2 to select the
operating mode of the board. For th
e 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.
5
. Power
Options
There are several ways of applying power to
the
TrxEB.

2 x 1.5
V AA batteries

USB

External
P
ower
S
upply

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. The external power supply
should set a voltage
that does not exceed
3.3 V.
B
y default, the MSP430 debugger supplies 3.0
V.
Note that there should only be one active
power source at any one time.
Warning!
To minimize risk of personal injury or
property damage, never use rechargeable
batteries to power the board.
Do not le
ave the
EVM powered when unattended.
6
.
Select Power Source
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.
The last
jumper in the row (pin 9
-
10) should always
be mounted, unless the MSP430 FET is
used as the power source.

.
Welcome Screen
Turn
on
power
with the Main Power
switch. You
should
now
see the Texas Instruments logo
and
a short d
escription of the buttons on the LCD.
Pushing any of the five buttons on the board will
take you to the main menu.
NB! If you don’t see anything on the screen
–
don’t panic.
First, make sure the mode switches
are in the correct positions (see step 4 above
).
Secondly, the first build of TrxEB unfortunately
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.

Select the PER (Pack
et Error Rate) test by
highlighting the selection
using the up/down
buttons. Confirm your selection by pressing
Enter (right button).
9
. S
elect
T
est
Mode
The PER test can be run is several modes. Easy
Mode sets up a one
-
way test and uses default
settin
gs. This test is convenient for practical
range testing.
The other test modes are described in the
“
Software Examples
for CC112x, CC11xL and
CC1101 U
ser’s Guide
”
.
To proceed, h
ighlight “Easy Mode” and press
Enter (right button).

10
. Select
Frequency
Select which frequency to use for the test. Make
sure that the evaluation modules you have
match the selected frequency.

. Select
Mode
One of the boards must operate as the slave
(transmitter) and the other as master (receiver).
Select
Slave
on one
board…
…and
Master
on the other board.

.
Establish Link
The slave node will now wait for a configuration
package from the Master. The configuration
contains the parameters used for the PER test.
The configuration package will be sent when you
se
lect “link devices” on themaster node.

Link E

When the initial linking has completed, the slave
node will start the test by co
ntinuously
transmitting packets to the master.

.
Start the R
eceiver (master)
On the master node, you c
an select the number
of packets you want to receive in order to
calculate the packet error.
When selecting “Start PER Test”, the master
(receiver) will begin to count the number of
received packets and provide some statistics.

Th
e master will display a window that plots the
received signal strength (RSSI) for each packet.
Press the “Up” button to go to the detailed
statistical window.

. PER Test R
esults
The statistics window will show the error rate
based on
the number o
f lost or erroneous
packets divided by the total number of packets
that should have been received.

. Troubleshooting
It you are experiencing problems with this test,
please check the following:

Nothing is shown in the display!
Unfortunately, the firs
t 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 CC11
2
0
/CC1121
receiver may experience saturation if it
is too
close to
the other CC112
0
/CC1121
transmitting at full output power.
