The FTXL Adapter Board
The primary function of the FTXL Adapter Board is to provide the 5 V power to
the FTXL Transceiver Board from the 3.3 V power of the DBC2C20 development
board. The FTXL Adapter Board also provides access to all of the FTXL
Transceiver I/O lines through headers on the board.
Connect the FTXL Adapter Board to the DBC2C20 development board by joining
the FTXL Adapter Board’s J7 and J5 connectors to the DBC2C20 development
board’s P22 and P23 headers.
Jumper Settings
The FTXL Adapter Board includes two sets of jumpers (J4 and J9). However, the
FTXL Developer’s Kit uses only the J9 jumper, as described in Table 6.

Connectors and Headers
The FTXL Adapter Board includes eight connectors and headers, of which the
FTXL Developer’s Kit uses the ones listed in Table 7 on page 14.
The FTXL Developer’s Kit does not use the J3 or J10 headers.
