3) Power on.
„ Jumper Pins Set Up
[JP4] (VDD2): Regulator (+3.3V) or VDD2 connector
OPEN:
The VDD2 pin is supplied via the VDD2 connector. <Default>
SHORT: The VDD2 pin is supplied via the regulator (+3.3V). (The connector “VDD2” must be open.)
[JP5] (D3.3V): Regulator (+3.3V) or D3.3V connector
OPEN:
Logic voltage is supplied via the D3.3V connector. <Default>
SHORT: Logic voltage is supplied via the regulator (+3.3V). (The connector “D3.3V” must be open.)
[JP6] (VDD): VDD1 and VDD2
OPEN:
Separated<Default>
SHORT: Connected
[JP7] (VDD1): Regulator (+3.3V) or VDD1 connector
OPEN:
The VDD1 pin is supplied via the VDD1 connector. <Default>
SHORT: The VDD1 pin is supplied via the regulator (+3.3V). (The connector “VDD1” must be open.)
The regulator can be supplied 3.3V to all circuits by shorting JP4, JP5 and JP7, and supplying +5V to REG+5V
