CHAPTER 12 CLICK 172/174

In order to mimic a traditional system, the rack card’s processor will sequence activation of

the primary and secondary outputs to signal the speed and duration detected by the radar

sensor. The duration of both outputs will be exactly the same.

With a 4-channel card, output channels 1 & 2 are paired to form one dual-loop emulation

system. Channel 1 is the primary channel for this pair, and channel 2 is the secondary. (The

other dual-loop emulation system is formed using output channels 3 & 4. Channel 3 is the

primary channel for this pair, and channel 4 is the secondary.) If any input channel (e.g.

lane 1) is assigned to both a primary and a secondary output channel, then the rack card is

automatically configured to provide dual loop-emulation (see Figure 12.6).

After you have configured the sensor using SmartSensor Manager, assign lane numbers to

each lane. The Click 172/174 cards will read the assigned lane numbers and display this

information during the configuration of the cards. The Click 172/174 card reads the first

character of the lane name that can take on a value of 0 to 9 and the direction the traffic is

flowing. For instance, if the innermost lane is named “1NB” and the direction of travel in

SmartSensor Manager is shown going from left to right, then the Click 172/174 will display

this lane as “1r.” If the inside lane on the other side of the median is named “1SB” and is

configured in SmartSensor Manager as going from right to left, the Click 172/174 will dis-

play this lane as “1L.”

Note

Lane names do not automatically contain a number as the first character. You must
change the lane name in SmartSensor Manager from “Lane_01” to “1Lane_01” or
“1NB.” In SmartSensor Manager HD, it is easiest to rename the lanes starting at the
lane furthest away from the sensor.
