SmartSensor Matrix Package
Selecting a Mounting Location
e Wavetronix SmartSensor Matrix™ is a stop bar presence detector designed for use at
signalized intersections (see Figure I.1). e SmartSensor Matrix detects vehicles through
the use of a 24.125 GHz (K band) operating radio frequency. Using what is classied as
frequency modulated continuous wave (FMCW) radar, SmartSensor Matrix detects and
reports vehicle presence in as many as 10 lanes simultaneously.
Figure I.1 – Wavetronix SmartSensor Matrix
SmartSensor Matrix is a rst-of-its-kind radar stop bar detector with Radar Vision™. It
delivers the reliability of radar and the simplicity of non-intrusive detection for stop bar
presence detection. In many situations, the sensor is installed on the roadside in order to
prevent the need for lane closures and trac control. Once the unit is installed, the congu-

ration process is quick and easy. Aer installation, the sensor will require little or no on-site
maintenance and can be remotely congured.
is user guide outlines the step-by-step process of installing and conguring the SmartSensor Matrix. Any questions about the information in this guide should be directed to
Wavetronix or your distributor.
SmartSensor Matrix Package
A standard SmartSensor Matrix package may contain some combination of the following items:
SmartSensor Matrix detector(s) with installed sensor backplate
Sensor mounting kit(s)
SmartSensor 6-conductor cable(s)
Intersection preassembled backplate, Click 650 cabinet interface device or Click 600
cabinet interface device
Click 112/114 detector rack card(s) with patch cable(s)
Click 104 four-channel DIN rail contact closure module
SmartSensor Manager Matrix (SSMM) soware
SmartSensor Matrix User Guide
Note
In addition to the intersection preassembled backplate and the Click 600/650 cabinet interface devices, you could also use the preassembled 19-inch rack or the segmented preassembled backplate. The coming chapters will discuss the dierences
between and uses of these various cabinet solutions.
SmartSensor Matrix installations should perform the following functions for the sensor:
AC power conversion – Provides reliable power for the sensors and other components.
is option is normally recommended instead of the DC surge protection because it
will not burden the existing DC power modules.
Surge protection – Protects equipment from surges coming from the power source or
from a cable run.
Remote IP connection – Provides a way (via a Click 301 serial to Ethernet converter, or
onboard Ethernet capabilities) to connect to the sensor from a remote location.
Figure I.2 shows several possible installation setups; these connect the sensor to a controller
by way of the Click 650, the Click 600 or a preassembled backplate. Some of these solutions
also require the use of contact closure cards in an input le rack.

Figure I.2 – SmartSensor Matrix System Options
Note
SmartSensor Matrix systems provide a control bridge to manage all connected SmartSensor and Click devices. The control bridge is completely separate from the dedicated
channels used for communication of contact closure detection calls in real time.
Selecting a Mounting Location
Consider the following guidelines when selecting a mounting location for each SmartSensor
Matrix:
Corner radar – e SmartSensor Matrix is a corner radar device with a panoramic
90°, 140-. (42.7-m) view (see Figure I.3). e sensor’s mounting location should be
selected so that all stop bar detection zones on an approach are within a 6–140-.
(1.8–42.7-m) radial distance.
8 INTRODUCTION SMARTSENSOR MATRIX USER GUIDE
140 ft
Sensor Pole
Figure I.3 – Corner Radar
140 ft
Line of sight – Position the sensor so that it will be able to detect the entire area of
interest. Avoid occlusion by installing the sensor away from trees, signs and other roadside structures.
Detection coverage – Position the sensor so that it will be able to reach all the specied
stop bar detection zones. e sensor will oen work better if you position it so that it
tracks vehicles for several feet before the rst zone in each lane. If the sensor has a view
several feet beyond the stop bar, it is more likely to accurately detect queue dissipation.
Closest roadside – Mount the sensor on the side of the road closest to the lanes of pri-
mary interest. Always mount the sensor high enough to prevent trac from occluding
approaching vehicles.
Mounting height – A minimum height of 12 . (3.6 m) is recommended. Mounting
the sensor higher will generally improve line of sight and decrease the possibility of
occlusion.
Mounting oset – A minimum oset of 6 . (1.8 m) to the rst lane of interest is
required.
Redundant detection – It is possible to have multiple sensors monitoring the same
approach. Multiple sensors are needed when zones are spread over more than 140 .
(42.7 m).
Sensor proximity – When multiple sensors are mounted at the same intersection, inter-
ference can be avoided by conguring each sensor to operate on a unique RF channel.
Departing lanes – ere is usually no need to view trac in departing lanes or to con-
gure departing lanes. However, if they are congured, then the stop bar should not
be congured.
Suspended electrical cables – e sensor is designed to work in the presence of sus-
pended power lines and other electrical cables. However, these cables should be at least
10 . (3 m) away from the front of the sensor.
Neighboring structures and parallel walls – e sensor should not be mounted with
signs or other at surfaces directly behind it. is will help reduce multiple reection
INTRODUCTION SMARTSENSOR MATRIX USER GUIDE 9
paths from a single vehicle.
Cable length – Make sure that you have sucient homerun and sensor cabling. Cable
runs as long as 500 . (152.4 m) can be achieved using 24 VDC operation and the system’s native RS-485 communications. If your application requires a cable length longer
than 500 . (152.4 m), contact Wavetronix Technical Services for assistance.
e SmartSensor Matrix should be mounted using one of the following options (see Figure
I.4):
➋
1 The back side of mast arm – is location allows the sensor to be placed near the lanes
of interest and may be the best location option for wide approaches. If you mount the
sensor on the back side of a mast arm, mount it near the end of the arm to reduce the
possibility of the mast arm or departing trac occluding approaching vehicles.
2 The far side of approach – e sensor is usually mounted on a corner vertical mast
pole or strain pole. If the sensor is mounted on a vertical pole with a mast arm, you
can usually avoid occlusion by mounting the sensor away from or below the mast arm.
3 The near side of approach – is mounting location is typically best if detecting the
le turn lane is less important. is location also allows you to mount the sensor high
enough to avoid occlusion.
Other mounting locations may be possible if these are not available at your intersection.
Contact Wavetronix Technical Services for assistance if you would like to use an alternative
mounting location.

Wavetronix or an authorized distributor.
14 CHAPTER 1 INSTALLING THE SMARTSENSOR MATRIX
Warning
Use caution when installing any sensor on or around active roadways. Serious injury
can result when installation is performed using methods that are not in accordance
with authorized local safety policy and procedures. Always maintain an appropriate
awareness of the trac conditions and safety procedures as they relate to specific
locations and installations.
Sensor Mounting Guidelines
e sensor is fairly insensitive to mounting height, but every site will vary based on lane
conguration and the presence of barriers and structures in and around the detection area.
e following table will help you determine how high to mount the sensor (see Table 1.1).
ese gures are only suggestions, but a good rule to follow is—the farther away the rst
lane is to the sensor, the higher you will want to mount the sensor to avoid occlusion.
Closest Lane Sensor Height
6–15 feet 12–25 feet
15–50 feet 15–25 feet
> 50 feet 25–60 feet
Table 1.1 – Suggested Mounting Guidelines
Note
In certain conditions, lanes that have stop bars or detection zones placed at extended
range may show some loss in performance, even with a proper mounting height. This
is more apparent at locations with many travel lanes or where detection zones are
placed near the far edges of detection. If you have any questions regarding the use
of SmartSensor Matrix at a particular location, please contact Wavetronix Technical
Services or your authorized Wavetronix dealer for more information.
Use the following guidelines to determine the best mounting height, then place your sensor
accordingly:
In general, the sensor should be placed at a height of roughly 20 . (6.1 m), give or take
5 . (±1.5 m).
e maximum recommended mounting height for the SmartSensor Matrix is 60 .
(18.2 m). e minimum is 12 . (3.6 m). Placing the sensor above or below these limits
will adversely aect detection accuracy.
CHAPTER 1 INSTALLING THE SMARTSENSOR MATRIX 15
Take into consideration the sensor’s eld of view, which reaches 140 . (42.7 m) from
the sensor. Place the sensor so that the eld of view covers all the areas of interest.
e mast arm is frequently a good place to mount the sensor.
e mounting position should have a clear view of the detection area. Poles, mast arms,
signal heads, or other objects should not block the view of the detection area.
Placing the sensor higher will result in less occlusion. Placing it lower could result in
more occlusion. However, if the nearest detection area is less than about 20 . (6.1 m)
away, the sensor may perform better with a lower mounting position.
Note
It is possible to mount the sensor lower than 12 ft. (3 m) in some scenarios. The sen-
sor will continue to detect vehicles at lower heights, but missed detections due to
occlusion may become more prevalent or problematic in lanes that are farther away
from the sensor.
Attaching the Mount Bracket to the Pole
Before attaching the mount bracket to the pole, rst make sure that your cables are long enough
to reach the sensor height and to stretch across the distance from the sensor to the cabinet.
Follow the steps below to correctly attach the mount to the pole:
1 Insert the stainless steel straps through the slots in the mount bracket.
2 Position the mount on the pole so that the head of the mount is pointing toward the
lanes of interest at about a 45° angle.
3 Tighten the strap screws.
Figure 1.1 – Attach the Mount Bracket to the Pole
e sensor double-swivel mount may need to be adjusted later to ne-tune the alignment.
16 CHAPTER 1 INSTALLING THE SMARTSENSOR MATRIX
One swivel joint is used to pan the sensor eld of view le or right and the other swivel joint
is used to tilt the sensor down towards the roadway. If you are not using the double swivelmount, make sure the pole straps are adjustable at this point in the installation process.
Attaching the Sensor to the Mount Bracket
Use the following steps to securely fasten the sensor to the mount bracket:
1 Align the bolts on the sensor’s backplate with the holes in the mount bracket. e eight-pin
connector receptacle on the bottom of the sensor should be pointing towards the ground.
2 Place the lock washers onto the bolts aer the bolts are in the mount bracket holes.
3 read on the nuts and tighten (see Figure 1.2)
Figure 1.2 – Attach the Sensor to the Mount Bracket
Caution
Do not over-tighten the fasteners.
Aligning the Sensor to the Roadway
e sensor’s beams fan out 45° to the le and 45° to the right, creating a 90° corner radar
eld of view. In most applications, you will want to position the corner radar so that its 90°
footprint covers all lanes approaching the stop bar (see Figure 1.3).

Figure 1.3 – Corner Radar Field of View Position
Stop Bar
To visualize the extent of the sensor eld of view, the 90° eld of view is imprinted on the top
and bottom of the sensor case. If more of a visual indicator is needed, then a square framing
tool (e.g. raer square) or other tool with a right angle can be held above the sensor. By looking down both edges of the tool, you can visualize the extent of the radar’s coverage.
Usually the front edge of the sensor’s eld of view is aligned to provide coverage beyond
the stop bar (see Figure 1.4). is allows you to place detection zones beyond the stop bar
to detect those vehicles that do not stop at or behind the stop line and will also allow the
sensor to see vehicles exiting queues. If the sensor pole is upstream from the stop bar, it is
recommended to pan in the direction of the stop bar.
Front edge of field of view
Figure 1.4 – Sensor Aligned by Rotating Towards the Stop Bar
Use the following steps to correctly align the SmartSensor Matrix:
1 Adjust the side-to-side angle so that the front edge of the eld of view provides a view
18 CHAPTER 1 INSTALLING THE SMARTSENSOR MATRIX
downstream of the stop bar.
2 Tilt the sensor down so it is aimed at the center of the lanes of interest.
3 If necessary, rotate the sensor so that the bottom edge of the sensor is parallel with the
roadway. is is necessary where the intersection approach has a signicant grade.
Note
To fully complete sensor alignment, you will need to connect to the Matrix sensor
using SmartSensor Manager Matrix and verify that your alignment is detecting the
vehicles in the lanes of interest (see Chapter 8).
Applying the Silicon Dielectric Compound
Use the following steps to correctly apply the silicon dielectric compound to the cable connector:
1 Tear the tab o of the tube of silicon dielectric compound.
2 Squeeze about 25% of the silicon onto the pins of the receptacle side of the connector
at the base of the SmartSensor Matrix (see Figure 1.5). Be sure to wipe o any excess
compound.
Figure 1.5 – Connector Receptacle
Connecting the SmartSensor 6-conductor Cable
e next step is to plug the SmartSensor 6-conductor cable into the connector. e sensor
connector is keyed to ensure proper connection (see Figure 1.6); simply twist the plug end
of the connector clockwise until you hear it click into place. To avoid undue movement
from the wind, strap the 6-conductor cable to the pole or run it through a conduit, but leave
a small amount of slack at the top of the cable to reduce cable strain. Route the cable from
the sensor location back to the main trac cabinet.
CHAPTER 1 INSTALLING THE SMARTSENSOR MATRIX 19
Figure 1.6 – Sensor 6-conductor Cable Connector
To set up your network in an orderly fashion, it is recommended that labeling be used
on the service end of each SmartSensor 6-conductor cable. A convenient way to label the
cables is to mark the last seven digits of the serial number on each sensor and the direction
of trac monitored (see Figure 1.7).
Figure 1.7 – Service End Labeling
Grounding the Sensor
e SmartSensor Matrix must now be grounded:
1 Connect a grounding wire to the grounding lug on the bottom of the sensor (see Figure
1.5).
2 Connect the other end of the grounding wire to the earth ground for the pole that the
sensor is mounted on. Do not attempt to run the grounding wire back to the main
trac cabinet.
20 CHAPTER 1 INSTALLING THE SMARTSENSOR MATRIX
Caution
Be careful of electrostatic discharge (ESD) when handling the SmartSensor Matrix
device before and during installation. ESD triggered by the sensor handler, particularly on the outer grounding lug before being properly grounded, may cause harmful
eects to internal Matrix components.

Once you have installed the sensor, the next step is to connect it into the larger installation
at the intersection—specically, to connect the sensor to equipment in the trac cabinet.
ere are several ways of doing this, but they all have the same purpose, which is providing
the sensor with the following:
Clean, reliable DC power
Surge protection
Communication (so that you can connect to the Matrix with the SmartSensor Manager
Matrix soware on your computer in order to congure the sensor)
A connection from the sensor to the intersection controller
e following three sections will talk about the three most common ways of setting up such
an installation. Note that all of the solutions below are designed to connect up for four sensors—one for each approach in a standard intersection.
22 CHAPTER 2 CABINET SOLUTIONS
Click 650
e cabinet solution recommended by Wavetronix is the Click 650 cabinet interface device.
Figure 2.1 – Click 650 Cabinet Interface Device
e Click 650 is a great choice for fullling all the requirements mentioned above using a
single device. An installation with the Click 650 will follow one of the basic outlines below:
Figure 2.2 – Click 650 Installation Basics
e sensor (or sensors) are connected to the Click 650 via ports on the back of the device.
Using this connection, the 650 provides the sensors with DC power, protects from surges
coming in on the cable run, and allows you to communicate with each sensor in order to
congure it. e Click 650’s Ethernet capabilities allow you to put the device on an Ethernet
network; once you’ve done this, the device (and its associated sensors) can be accessed via
web browser on any computer on the same network.
CHAPTER 2 CABINET SOLUTIONS 23
Note
The Click 650 can also be used with the SmartSensor Advance.
e Click 650 provides two ways to get sensor detection data to the controller:
Via an SDLC bus (upper portion of Figure 2.2). is option only works if the cabinet is
a NEMA TS-2 type 2 cabinet, but for those cabinets that allow it, this is an extremely
easy way to communicate with the controller (and one that requires less hardware).
Via contact closure cards (lower portion of Figure 2.2). For cabinets that don’t support
SDLC, you can connect the 650 to contact closure cards, through RJ-11 jacks on the
faceplate of the device, and then connect from there to the controller.
For more information about this device, consult the Click 650 user guide or take the Click
650 training course.
Click 600
Another popular solution is the Click 600 cabinet interface device.
Figure 2.3 – Click 600 Cabinet Interface Device
e Click 600 is similar to the Click 650, but has fewer features. In certain situations, however, you may nd this device preferable to the Click 650.
e Click 600 diers from the Click 650 in the following ways:
e Click 600 has no Ethernet connections. Network access using the Click 600 will re-
quire a separate Ethernet-capable device (such as the Click 301) attached to the T-bus.
No OLED screen and menu, which on the Click 650 allows you to congure certain
aspects of the device and view information about it.
No SDLC connection; data must be pushed to the controller via contact closure cards
attached to the RJ-11 jacks on the faceplate of the device.
24 CHAPTER 2 CABINET SOLUTIONS
An installation with the Click 600 will follow the basic outline below:
Figure 2.4 – Click 600 Installation Basics
Similar to the Click 650, with the Click 600 you connect sensors (Matrix and/or Advance)
to the four ports on the back of the device. e 600 pushes that data out via the RJ-11 jacks
to connected contact closure cards in an input le rack. is rack then communicates the
detection data to the controller.
For more information about this device, consult the Click 600 quick reference guide.
Preassembled Backplate
e third option is the preassembled backplate, oered by Wavetronix.
Figure 2.5 – Preassembled Backplate
Unlike the cabinet interface devices, which combine all necessary functions in a single device, the backplates bring together a number of devices to support the sensor. e disadvantages of this include more complicated wiring as well as increased space demands. However,
the advantage of the preassembled backplates are that they are customizable; needed but
nonstandard devices can easily be added, you can get backplates that accept DC power
instead of AC, etc.
CHAPTER 2 CABINET SOLUTIONS 25
Figure 2.6 – Preassembled Backplate Installation Basics
If you use the preassembled backplate, you’ll connect the sensor or sensors to the terminal
blocks on the bottom row of the backplate. e Click devices on the upper row will provide
surge protection and clean DC power for the devices, as well as RJ-11 jacks that you’ll connect to contact closure cards in an input le rack. is rack will then send detection data
on to the controller.
Note
There are a few alternate versions of the preassembled backplate: the preassembled
19-inch rack for server racks and the intersection segmented preassembled backplate
for easier installation in trac cabinets (this device has the necessary components
spread across a few smaller backplates; these can be helpful in cabinets where space
is tight because they don’t require such a large block of space to be made available).
For more information about the preassembled backplate, see Appendix D in this guide.
Terminating SmartSensor 6-conductor Cables
Each of the cabinet solutions discussed up to this point uses the same method for terminating the 6-conductor cable coming from each sensor: they must be landed into plugs that t
the terminal blocks on the backplate and the sensor ports on the cabinet interface devices.
(see Figure 2.7 and Table 2.1).
26 CHAPTER 2 CABINET SOLUTIONS
Figure 2.7 – Color Label on Plug-in Terminals
Each 6-conductor cable has one DC power wire pair, two RS-485 communication pairs,
and a drain wire (see the above gure). Follow the steps below to land the sensor cables into
the plugs.
1 Aer routing your SmartSensor 6-conductor cable into the cabinet, carefully strip back
the cable jacket and shielding on the service end of the cable.
2 Open the insulation displacement connectors on the plug by inserting a small screw-
driver into each square slot and rocking it back.
3 Insert the wire leads into the bottom side of the plug-in terminal according to the color
code shown in Table 2.1 and Figure 2.7. Make sure the wires are completely inserted
in the terminal.
4 Close the insulation displacement connector by reinserting the screwdriver into the
square slot and rocking it forward. e plug-in terminals will automatically complete
the electrical connection. ere is no need to manually strip the insulation on the end
of each wire.
Do not strip the service end of the cable until aer it has been routed through conduit. e
cable should be one continuous run without any splices.
CHAPTER 2 CABINET SOLUTIONS 27
Note
If you’re using a preassembled backplate, the plug features two measures to ensure
that it’s always returned to their correct terminal block sections.
First, for visual confirmation, one part of the plug is blue (see Figure 2.7) and must be
visually matched up to a blue terminal block. The location of the blue piece rotates in
the dierent plugs and terminal block sections: in the first, the first block is blue, in
the second, the second is blue, etc.
Second, the plugs are keyed, as shown in the blue piece in Figure 2.7, so they will only
fit into their correct terminal block sections.
