Using the Click 512

The Click 512 monitors per-vehicle lane, speed, length, direction, and class information from a SmartSensor HD. 

The Click 512 compares the per-vehicle data from SmartSensor HD to a set of user-configured speed and length 

thresholds. There are separate thresholds for each of the eight possible outputs. The Click 512 also forwards 

data from the relevant lanes to the front serial port for data logging and/or troubleshooting. If a detected vehicle 

exceeds or is less than the given criteria, then an alert will be triggered on the digital output corresponding to that 

channel (or to a Click 104 output). Digital outputs 1 and 2 are contact closure outputs and can be wired to a traffic 

cabinet contact closure input or to an electrical relay. The Click 120 relay provides a simple way to turn on or off 

an AC or DC powered load based upon the alert output.

Note. 

Wrong way detection is done using the under-speed condition. Once the under-speed condition is selected 

and the condition is met, an alert will trigger through the contact closure and an ASCII string will be transmitted 

through the DB-9 port.

A possible application for the Click 512 is to warn specific drivers of a potentially dangerous roadway. If a vehicle 

is detected to exceed the user-configured speed and length thresholds, the Click 512 can trigger a warning sign 

that tells the driver to slow down. For example, if the length threshold is set to 13 ft. and the speed threshold is set 

to 65 mph, a vehicle that is detected to be 14 ft. long and going 70 mph will trigger an alert, as would any vehicle 

that is both faster than 65 mph or longer than 13 ft.

Note. 

Timing of the warning sign alert is important to the application. Three methods of trigger synchronization 

are presented later in this document. Typically you will need a distance of 300–600 feet between the sensor and 

the warning sign.

The Click 512 utilizes the Click Supervisor software for user configuration of vehicle speed and length thresholds 

and output variables. Communication between the Click 512 and Click Supervisor is easy to set up and use.

Physical Features

The Click 512 is based upon the Click 500 platform, so it has the same physical features as the Click 500.
