OPERATION 

Here are the instructions to power up the PCB and modules. 

Power up sequence  

To power up and configure the evaluation card, please follow the steps as described below. 

1.

 

Initial set position of the enable switch 

 

Please make sure the OUTPUT ENABLE toggle switch (S201) is 

in the “disable” 

orientation as shown below with the toggle of the switch leaning toward the modules 
and the output side of the PCB (and away from the input side of the board).
