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 settings 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, first ad-
just the default loop size and spacing to match the inductive loop setup that you’re try-
ing 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.
