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 AD-
BMSE2E3W-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 counter-
clockwise (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 AD-
BMSE2E3W-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) to the
TP16 (VBAT+ terminal) of the AD-BMSE2E3W-SL board. See
Figure 3
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 AD-
BMSE2E3W-SL.
9. Set the DC2472A battery emulators to the highest voltage
by fully turning the cell voltage adjustment potentiometer clock-
wise.
10. Check the supply for the test points. Make sure that the voltage
levels are within the specified range stated in
