DETAILED DESCRIPTION
The ADXL202EB-232A is a dual axis RS-232
output digital accelerometer. The ADXL202EB-232
consists of the ADXL202JQC and the Microchip
16C63 microcontroller. The ADXL202 digital
outputs are read using the timer / counter port of the
microcontroller.
high and low times to a duty cycle in %. The X and
Y duty cycle values are sent when requested. The
board is powered by an extra control signal, RTS, on
the RS-232 port. The voltage regulator is the low
power ADM666.

Demo Board LED
The LED on the demo board should blink 5 times
when it is connected to the serial communication
port. This indicates that the demo board has power-

begin communication with the host software. If this
doesn’t happen press the reset button. If there is still
a problem please see the troubleshooting section.

previously defined connections. Choose the one that
has the correct com port and the ADXL202EB-
232A.
If everything is ok, you will see a green LED appear
with the phrase “ADXL202-232A connect on
COMx. Connected at 38400 baud”. Where ‘x’ is
the number of the serial communication port that
was defined.
