2.1.3 Connect the Power Supplies to the Boards (Power Off)

  1. Confirm the power switch on the TSW14J59EVM is in off position. Connect the power cable to a 12V DC (minimum 5A) power supply. Make sure the proper supply polarity by confirming the outer surface of the barrel connector is GND and the inner portion of the connector is 12V. Connect the power cable to the TSW14J59EVM power connector.
  2. DAC39RF20EVM can be powered with 12V DC (minimum 3A) though the connector jack (J2) on the DAC39RF20EVM, or the EVM can be powered from the TSW14J59EVM by FMC+ connector. There is a switch (SW1) which can be used to select power from the barrel jack on the DAC EVM, or from TSW14J59EVM through FMC+ connector. Confirm that the power switch for the DAC39RF20EVM power supply is set to the opposite position (jack) from where the the EVM is drawing power. If using barrel jack option, then connect the power cable to a 12V DC (minimum 3A) power supply. Make sure the proper supply polarity by confirming that the outer surface of the barrel connector is GND and the inner portion of the connector is 12V. Connect the power cable to the EVM power connector. Table 2-1 is used as a reference to power the DAC39RF12EVM.
