7.2 Running the Demo on Two Boards

To run demo on two boards, perform the following steps:

  1. Place the Transmitter (Tx) and Receiver (Rx) antennas with in 1 meter range. The range limitation is due to the limited RF gain of AD9371. The range is extended by using a RF amplifier at transmitter output.
  2. After programming the bit files, launch the GUI in the PC where Transmitter antenna is connected.
  3. Select the appropriate port for the communication in Connection tab and click Connect.
  4. Check for the connection status at right bottom corner of the GUI.

  5. By this, point connection is established and GUI is ready to send or receive the data.
  6. Repeat the same steps for the PC connected to the Receiver antenna.
  7. You can send data in the following two ways:
    1. Enter data and click Send .
    2. Click Send from File .
