Operation
The ZMOTION Detection Module Development Kit provides various features to control
its overall operation. It operates in two basic modes:
•
Hardware Interface Mode
•
Serial Interface Mode
Each of these modes is described in this section.
Hardware Interface Mode
Hardware Interface Mode provides the simplest mode of operation and allows basic con-
trol of the ZMOTION Detection Module with hardware jumpers and potentiometers. In
this mode, the serial interface is disabled and the trim pots on the Development Board
(Sensitivity, Delay and Ambient Light Threshold) are used to control operation.
To enable Hardware Interface Mode and test its basic operation, observe the following
steps.
1. Place SW1 in the HARDWARE position.
2. Turn the AMBIENT potentiometer fully clockwise (towards ‘+’) to set the ambient
light threshold to maximum. Essentially, the maximum amount of ambient light will
be required to disable the Motion Detection output (LED). For details about the
AMBIENT pot, see
3. Turn the DELAY potentiometer fully counterclockwise (towards ‘–’) to select the
minimum LED “on” time (2 seconds). For details about the DELAY pot, see
4. Turn the SENSITIVITY potentiometer fully clockwise (towards ‘+’) to select the
maximum motion-detection sensitivity. For details about the SENSITIVITY pot, see
5. Press Reset or apply power.
At this point, the ZMOTION Detection Module will power-up and check the voltage
applied to the TXD/SNS pin to determine its Interface Mode. With SW1 in the
