  3. The 12V supply must be connected to J12 on the AWR2944EVM/AWR2944PEVM.
  4. A 5V supply must be connected to J2 on the DCA1000 EVM.
  5. A micro USB cable must be connected to the FTDI port on the AWR2944EVM/AWR2944PEVM (J10).
  6. The Samtec ribbon cable must be connected to J7 on the AWR2944EVM/AWR2944PEVM and J3 on the DCA1000 EVM.
  7. An RJ45 cable must be connected to J6 on the DCA1000 EVM.
