Controlling Operation in Hardware Interface Mode
Serial Interface Mode
Serial Interface Mode provides more control over the operation of the ZMOTION
Module by providing a serial command interface to monitor and control the device. In Serial
Interface Mode commands are sent over the provided DB-9 RS-232 interface. Refer to
PS0284 for a complete list and description of commands supported.
1. Slowly rotate the “AMBIENT” potentiometer while creating motion in front of the lens
2. Return the “AMBIENT” potentiometer to its fully clockwise position.
3. Rotate the “DELAY” potentiometer slightly clockwise to increase the amount of time
4. Return the “DELAY” potentiometer to its fully counter-clockwise position.
5. Decrease the sensitivity by rotating the “SENS” Potentiometer counter-clockwise and
1. Connect the provided serial cable between the DB9 connector on the Evaluation Board
2. Using HyperTerm or some other serial terminal program, set the interface to:
3. Place SW1 in the ‘SERIAL’ position
4. Turn the Ambient Pot fully clockwise (towards ‘+’) to set the ambient light threshold to
5. The DELAY and SENS potentiometers are not used in Serial Interface Mode
6. Press Reset or apply power.
7. After power-on, the ZMOTION
(wave your hand in front) until the LED stops turning on. This is the threshold of the
ambient light in your room. In lighting control applications, this allows you to adjust the
amount of ambient light allowed in the room without turning the lights on when motion
is detected – That is; the lights are not turned on when it is already bright enough in the
room.
the LED stays on after motion is detected.
observe that additional motion is required to turn on the LED or that the
“range/distance” of detection is decreased.
and a serial port on your PC.
maximum. This means that it will require the maximum amount of ambient light to
disable the Motion Detection output (LED).
At this point the ZMOTION
applied to the TXD/SNS pin to determine the Interface Mode. With SW1 in the
“SERIAL” position, the voltage on this pin will be greater than 2.5V, selecting Serial
Interface Mode. The interface mode is detected once only after reset, while the
ambient light threshold is monitored continuously.
stabilize before it starts ‘looking’ for motion. This power up delay can take a few
seconds up to a maximum of about 30 seconds.
