.
2. Connect a 5-V wall-wart connector or other power source for the TSWDC155EVM (sold separately). The
TSWDC155EVM user guide provides information on this power source.
3. Physically connect J1 of the TSWDC155EVM to J27 of the ADS9218EVM. This component is the digital
communications and power signal connection.
4. Connect the USB on the TSWDC155EVM to the computer.
5. Set jumper J18 to the FMC_PWR position to allow for an external power connection. Connect an external
5.2-V to 5.5-V supply on screw terminal connection J17.
