Enable Speed Failsafe
In a small percentage of cases, the SmartSensor HD may not report a valid speed.
Check this box if you want vehicles that have an invalid speed (but that exceed the
length threshold) to trigger an output.
Logic AND Outputs with Input 1
Allows you to gate the activation of outputs based upon an external signal wired to
digital input 1.
Logic AND Outputs with Input 2
Allows you to gate the activation of outputs based upon an external signal wired to
digital input 2.
Time Zone
Sets the time zone of the timestamp on the data; you can view this using
HyperTerminal or another serial terminal program. The time of events is time stamped
using SmartSensor HD’s real-time clock, which is set to UTC (GMT). Using this setting,
you can tell the Click 512 to convert that time into the time zone of your choice.
The SmartSensor HD timestamps are referenced to the time that the front-edge of the vehicle enter the detection
beam. However, the event message itself will not be reported until about one second after the back-edge of the
vehicle leaves the detection beam.
Note.
Invalid speed entries will show a value of 512 mph in the serial transmitted text strings.
There are nine other tabs you can access. They correspond to the eight possible contact closure outputs the
Click 512 can be configured to deal with. The other eight tabs are labeled
O1
through
O8
. These tabs allow you
to configure the following for each alarm: the lanes affected, over speed and under speed thresholds, length
thresholds, the duration of the contact closure, and the delay between detection and output.
All nine of these tabs have the following settings:
Setting
Description
Lower Lane Limit
In conjunction with the Upper Lane Limit, this allows you to filter which lanes are mapped to this
output. Lanes are assigned a number 1 through 10, with 1 being closest to the sensor. Lanes greater
than or equal to the lower lane limit will be mapped to the associated output (There are 8 outputs
labeled O1 to 08 on the tabs.)
Upper Lane Limit
In conjunction with the Lower Lane Limit, this allows you to filter which lanes are mapped to this
output. Lanes less than or equal to the Upper Lane Limit will be mapped to the associated output.
For example, if the Upper Lane Limit and Lower Lane Limit are both equal to 4, then only detections
from lane 4 can trigger the output.
Over Speed
Sets the default value for the over speed threshold. When enabled, vehicles that have a speed that
exceeds this value will trigger an output. When disabled the speed threshold is ignored.
