Note
The SmartSensor default loop size and spacing will change the values of
SmartSensor data. The default loop size is used in the calculation of lane
occupancy, vehicle duration and vehicle length. The default loop spacing
is used in the calculation of vehicle speed and length. The Click! 100 and
172/174 also use these seings to change the duration and spacing of contact
closures signaled on their output pins. If your SmartSensor is connected to
a contact closure device and you are also retrieving data serially, rst adjust
the default loop size and spacing to match the inductive loop setup that
you’re trying to emulate, then adjust the individual lane size and spacing
values used to calculate the per lane scale factors.
Click! 500 –

The Click! 500 modules support baud rates from 9600 to
115200 bps. Any special programming of SmartSensor for an application
running on the Click! 500 will be explained in the documentation for that
application.
Programming Contact Closures
The contact closure modules have several modes of operation explained in their
respective quick-start guides and user manuals. Consult this documentation to
determine the mode appropriate for your application. This documentation will
explain how to program each mode.
