1.3.1 Hardware Setup

Figure 3-26 shows the board overview for hardware settings.

Use the following procedure when setting up the board:

  • Make sure no power source is connected to the board.
  • Insert the 280049C controlCARD in the J5 slot.
  • Connect a power source for the primary and secondary side (+12 V, 1 A) at the test points
  • Switch the power source on for both the primary and secondary side. A green LED on the control card lights up. This indicates the C2000 MCU device is powered.
  • To connect JTAG, use a USB cable from the controlCARD and connect the cable to a host computer.
  • Connect the DC power supply to the input connector (J1 and J2) and the electrical load to the output connector (J10 and J11).
