Figure 22. Antenna Diversity Testcard
Note: Depending on antenna selection the relevant antennas are shown on the top row and either ANTDIV, A_DIV(1), or
A_DIV(2) is shown in the second line of text.
The ready screen is designed to allow you to review the settings on both boards. In the example shown above, we
illustrate the following configuration:
 Our first board with ID 091 is sending its message to board with the ID 094
 At 2.4 kbps
 With frequency 868.00 MHz
Using the ready screen, we can see that there is an error on the split TX/RX board in that it is configured with a
selfID of 054, this does not match the DestinationID on the antenna diversity board. From the 'ready screen' we
can update the antenna diversity board accordingly. To do this, we can press PB3 or PB4, which are highlighted as
'SETTINGS' where we can re-run the setting accordingly.
Once the settings are correct we can run the demonstration accordingly.
If the user has the ability to see both ends of the link then a white LED driver is made available on the SDB with
which you can enable a high brightness LED to make visual confirmation easier of the remote board.
