4.1 Hardware Set-up

Follow these steps to setup the EVM prior to launching the GUI:

  1. It is advised to make any jumper configuration changes prior to powering the EVM. The NAD_nFAULT_x headers should be selected as desired prior to powering up the board.

  2. Connect micro-USB cable to J6 (Figure 2-1). For proper GUI application operation, it is important to connect the EVM USB cable to a computer prior to applying VSUP power to the EVM. For standalone EVM testing a USB connection is not necessary.

  3. With the VSUP external supply outputs disabled, connect +BAT supply to the screw terminals on the EVM (J14), observing polarity (Figure 2-1).

  4. Energize the VSUP supply. PVDD LED D3 and 3.3V_MCU LED D7 will illuminate. If PVDD LED does not illuminate, verify polarity and check fuse(s) are installed and have continuity.

  5. After applying VSUP supply, LED D6 illuminates to indicate that there is a successful USB connection with the computer. If LED D6 is NOT ON, disconnect USB cable from computer, turn-off power supply, re- connect USB to computer, and turn-on the supply.

  6. The EVM is ready to be used with the GUI application (Section 4.2). In certain situations, such as while disconnecting and reconnecting VM power before the power supply capacitors are fully discharged a proper firmware reset may not happen. If the Status LED (D1) is not blinking as expected, press the reset push button once with jumper J1 installed in the RST position. Do not unplug the USB cable while the VM power is active. If you do, switch off the VM power, wait until it is fully discharged and proceed to step 2.

  7. The latest version of the GUI application is bundled with the latest version of the EVM firmware. It is recommended to do a firmware update before selecting and connecting to an EVM variant using the GUI application.
