Software

The board ATAB5749 is be delivered with default settings as detailed in the 

Table 1-2

 below.

In order to use the ATAB5749 board, an additional board as well as the RF Design Kit software is needed. Either the 
ATAB-RFMB or ATAB-STK-F is used as a microprocessor board interfacing the RF Design Kit software and the transmitter 
board. For further information about the hardware refer to the application notes “ant_hd-rf-desing-kit_041105_sec.pdf” and 
“ant_hd-flamingo_181105_sec.pdf”.
