HARDWARE SETUP

Follow these steps to set up the AD-BMSE2E3W-SL hardware:

1. Screw the two-cell connector blocks to the two DC2472A battery emulators. Note that the first two terminals and the last terminal of each DC2472A connector must be left hanging (see Figure 2).
2. Connect the DC2472A battery emulators to the ADBMSE2E3W- SL board through the cell connector blocks.
3. Set the DC2472A battery emulators to the lowest voltage by fully turning the cell voltage adjustment potentiometer counterclockwise (see Figure 2).
4. Connect a micro-USB Type B cable to each DC2472A battery emulator and power the board by connecting the other end of the cable to the Host PC.
5. Attach the MAX32625PICO programmer to the ADBMSE2E3W- SL board (through the SWD connector) using the 10-pin ribbon SWD cable.
6. Power the MAX32625PICO board using a micro-USB to USB cable connected to the Host PC.
7. Connect the alligator clip cable (red) to the VBATTP Pin or the third of the Pin 17 header of the DC2472A battery emulator.
   • Then, insert the other end of the cable (banana jack plug) into the TP16 (VBAT+ terminal) of the AD-BMSE2E3W-SL board. See Figure 3 for the pin locations.
8. Connect the alligator clip cable (black) to the GND (VBAT-) supply of the DC2472A battery emulator. Then, connect the other end of the cable to the Rsense (top side) of the ADBMSE2E3W- SL.
9. Set the DC2472A battery emulators to the highest voltage by fully turning the cell voltage adjustment potentiometer clockwise.
10. Check the supply for the test points. Make sure that the voltage levels are within the specified range stated in Table 1.
