1. Kit Contents

The following items are included in the
CC85XXDK:

2 x Purepath Wireless AudioEB
1 x CC Debugger
2 x CC85xxEM
2 x CC85xx-CC2590EM
2 x 2.4 GHz Antennas
Cables
Documentation

The RF boards in this kit are FCC and IC
certified and tested/comply 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.

2. Purpose of this Quick Start
Guide

This quick start guide will provide step-by­step instructions showing how to set up an
audio link between two wireless units
provided in the development kit. The
procedure is the same regardless of which
evaluation module is being used, i.e.
either the C85xxEM or the CC85xx­CC2590EM.

The EMs are pre-programmed with
firmware to stream audio from the
(Master) line-in input of one AudioEB to
the (Slave) line-out and headphone output
on the other AudioEB. Please follow step
2 to 9. For the latest firmware revision see
step 10.

For more details on CC85xx, see the
product folder of the CC8520 [1].

Caution! To minimize risk of
injury, avoid touching
components during operation
if symbolized as hot.

Caution! The kit contains
ESD sensitive components.
Handle with care to prevent
permanent damage.

3. Plug Master EM into PPW
Audio EB

Connect the CC85xxEM or the CC85xx­CC2590EM marked MASTER (label
attached on the backside of the board).
These boards are pre-programmed with
master firmware. Attach the antenna to
the SMA connector.

4. Plug Slave EM into PPW
Audio EB

Connect the CC85xxEM or the CC85xx­CC2590EM marked SLAVE (label
attached on the backside of the board.)
These boards are pre-programmed with
slave firmware. Attach the antenna to the
SMA connector.

5. Connect Audio Cables to the
Master

Connect an audio source (CD-player,
MP3-player or similar) to the line-in input
of the AudioEB with CC85xxEM or
CC85xx-CC2590 with the “MASTER” label
plugged in.

The CC85xx-CC2590EM and CC85xxEM
with the “MASTER” label are pre­programmed with firmware which sets up
the onboard TLV320AIC3101 codec [2] to
use analog input on the PPW AudioEB.

6. Connect Audio Cables to the
Slave

Connect an amplifier to line out or connect
a headphone to the mini jack of the
AudioEB with the CC85xxEM or the
CC85xx-CC2590 with the “SLAVE” label
plugged in.

The CC85xx-CC2590EM and CC85xxEM
with the “SLAVE” label are pre­programmed with firmware which sets up
the onboard TLV320AIC3101 codec [2] to
use line out and headphone output of the
PPW AudioEB.

7. Power

To power the PPW AudioEBs; connect a
USB cable to each of the PPW AudioEBs
and make sure J10 is in the position

“OUT-USB” (Pos 1-2). Finally, switch P6
to “ON”. The LED D3 should now be lit.

Note! When using the DC jack connector
or screw terminal to power the AudioEB,
the power source should be in a range
from 5.5V to 15V with a maximum current
source capability of 1A.

There should only be one
active power source at
any one time. Do not
leave the board powered
when unattended.

8. Pairing

When powered for the first time, LED D9
will blink to indicate that the devices are
not connected.

To pair the Slave with the Master; click
first on SW9 on Master and then click on
SW9 on the Slave within a few seconds
after you clicked on the Masters SW9.
When the devices are paired and the link
is established, LED D9 will be constantly
lit.

Note that the pairing operation is only
needed the first time. Next time they will
pair automatically when powered.

You can now turn on your audio source
and start testing!

9. Volume control

The output volume can be adjusted on the
Slave by pressing SW 1 to increase the
volume and SW3 to decrease the volume.

10. PurePath Wireless
Configurator

The next step is to download the PurePath
Wireless Configurator (PPWC). PPWC
makes it possible to explore all the
configuration options of the CC85xx
family. After creating device configurations
for Master and Slave network roles,
PPWC can program the CC85xx devices
directly through the CCDebugger
(included in the kit).

For more details; download the PPW
Configurator and the PPW Configurator
Quick Start Guide. Links to download the
PPW Configurator can be found in the
CC8520 product folder [1]
