3. Connect the power supply.
First, prepare the AC adapter for the country where it will be used by selecting the plug.
The BL2000 Tool Kit presently includes Canada/Japan/U.S., Australia/N.Z., U.K., and
European style plugs. Snap in the top of the plug assembly into the slot at the top of the
AC adapter as shown in Figure 4, then press down on the spring-loaded clip below the
plug assembly to allow the plug assembly to click into place.
Connect the bare ends of the power supply to the +RAW and GND positions on screw-
terminal header J2 as shown in Figure 4.

4. Apply power.
Plug in the AC adapter. If you are using your own power supply, it must provide 9 V to 40 V
DC—voltages outside this range could damage the BL2000.
CAUTION: Unplug the power supply while you make or otherwise work with the connections
to the headers. This will protect your BL2000 from inadvertent shorts or power spikes.
NOTE:
The green PWR LED and the red BAD LED on the opposite end of the board
should come on, indicating that the BL2000 is now ready to be used.
NOTE: A hardware RESET is done by unplugging the AC adapter, then plugging it back in,
or by momentarily grounding the board reset input at pin 9 on screw-terminal header J2.
