"UART". This configuration will make it possible
to communicate directly with the MSP430 over a
virtual COM port on the PC.

7. Welcome Screen

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.
NB! If you don't see anything on the screen
make sure the mode switches are in the
correct positions (see step 4 above).

External Power Supply Requirements:
Nom Voltage: 3.3VDC
Max Current: 800 mA
Efficiency Level V
Warning! To minimize risk of personal injury or
property damage, never

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. 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
use rechargeable
the EVM powered when unattended.

9. Select Test Mode

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".
To proceed, highlight "Easy Mode" and press
Enter (right button).
