    SWRU252B     September 2012   CC85XXDK Quick Start Guide   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-by-step 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  CC85xx-CC2590EM.  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  CC85xx-CC2590EM  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  CC85xx-CC2590EM  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  pre-programmed 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  pre-programmed with firmware which sets up the onboard TLV320AIC3101 codec [2] to use line out and headphone output of the PPW AudioEB.
    SWRU252B     September 2012   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).
