In this chapter  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 classied 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 MatrixSmartSensor 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 trac control. Once the unit is installed, the congu-Introduction

After installation, the sensor will require little or no on-site maintenance and can be remotely congured. is user guide outlines the step-by-step process of installing and conguring the Smart-Sensor Matrix. Any questions about the information in this guide should be directed to Wavetronix or your distributor.SmartSensor Matrix PackageA standard SmartSensor Matrix package may contain the following items: SmartSensor Matrix SS225 detector(s) with installed sensor backplate Sensor mounting kit(s) SmartSensor 6-conductor cable(s) Intersection preassembled backplate Click 112/114 detector rack card(s) with patch cable(s) Click 104 four-channel DIN rail contact closure module SmartSensor Manager Matrix (SSMM) software SmartSensor Matrix User GuideNoteInstead of the intersection preassembled backplate, you may be using the Click 600 cabinet interface device, the preassembled 19-inch rack, or the segmented preas-sembled backplate. The coming chapters will note installation dierences between these devices and the preassembled backplates where applicable.SmartSensor Matrix system options include (see Figure I.2): AC power conversion – Provides reliable power for the sensors and backplate com-ponents. is option is normally recommended instead of the DC surge protection because it will not burden the existing DC power modules. Remote IP connection – Provides a way (via a Click 301 serial to Ethernet converter) to connect to the sensor from a remote location. e Click 301 is recommended for remote management.

The control bridge is completely separate from the dedicated channels used for communication of contact closure detection calls in real time.Selecting a Mounting LocationConsider the following guidelines when selecting a mounting location for each SmartSen-sor Matrix: Corner radar – e SmartSensor Matrix is a corner radar device with a panoramic 90°, 140-ft. (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-ft. (1.8–42.7-m) radial distance.
8 INTRODUCTION  SMARTSENSOR MATRIX USER GUIDE140 ftSensor Pole140 ftFigure I.3 – Corner Radar 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 specied stop bar detection zones. e sensor will often 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 primary interest. Always mount the sensor high enough to prevent trac from occlud-ing approaching vehicles. Mounting height – A minimum height of 12 ft. (3.6 m) is recommended. Mounting the sensor higher will generally improve line of sight and decrease the possibility of occlusion. Mounting oset – A minimum oset of 6 ft. (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 ft. (42.7 m). Sensor proximity – When multiple sensors are mounted at the same intersection, interference can be avoided by conguring each sensor to operate on a unique RF channel. Departing lanes – ere is usually no need to view trac in departing lanes or to congure departing lanes. However, if they are congured, then the stop bar should not be congured. 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 ft. (3 m) away from the front of the sensor. Neighboring structures and parallel walls – e sensor should not be mounted with
INTRODUCTION  SMARTSENSOR MATRIX USER GUIDE 9signs or other at surfaces directly behind it. is will help reduce multiple reection paths from a single vehicle. Cable length – Make sure that you have sucient homerun and sensor cabling. Cable runs as long as 500 ft. (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 ft. (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):➌➋➊Figure I.4 – Mounting locations1 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 trac 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 left 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.

14 CHAPTER 1  INSTALLING THE SMARTSENSOR MATRIXWarningUse 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 trac 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 conguration 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 Height6–15 feet 12–25 feet15–50 feet 15–25 feet> 50 feet 25–60 feetTable 1.1 – Suggested Mounting GuidelinesNoteIn 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 ft. (6.1 m), give or take 5 ft. (±1.5 m). e maximum recommended mounting height for the SmartSensor Matrix is 60 ft. (18.2 m). e minimum is 12 ft. (3.6 m). Placing the sensor above or below these limits will adversely aect detection accuracy.
CHAPTER 1  INSTALLING THE SMARTSENSOR MATRIX 15 Take into consideration the sensor’s eld of view, which reaches 140 ft. (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 ft. (6.1 m) away, the sensor may perform better with a lower mounting position.NoteIt 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 PoleBefore 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 MATRIXOne swivel joint is used to pan the sensor eld of view left or right and the other swivel joint is used to tilt the sensor down towards the roadway. If you are not using the double swivel-mount, make sure the pole straps are adjustable at this point in the installation process.Attaching the Sensor to the Mount BracketUse 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 after 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 BracketCautionDo not over-tighten the fasteners.Aligning the Sensor to the Roadwaye sensor’s beams fan out 45° to the left 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).
CHAPTER 1  INSTALLING THE SMARTSENSOR MATRIX 1745°45°Edge of first lane of interestStop BarPan sensor towards stop barFigure 1.3 – Corner Radar Field of View PositionTo 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. rafter 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 viewFigure 1.4 – Sensor Aligned by Rotating Towards the Stop BarUse the following steps to correctly align the SmartSensor Matrix:
18 CHAPTER 1  INSTALLING THE SMARTSENSOR MATRIX1 Adjust the side-to-side angle so that the front edge of the eld of view provides a view 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 signicant grade.NoteTo 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 CompoundUse the following steps to correctly apply the silicon dielectric compound to the cable con-nector: 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 (left) and Grounding Lug (right)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 trac cabinet.
CHAPTER 1  INSTALLING THE SMARTSENSOR MATRIX 19Figure 1.6 – Sensor 6-conductor Cable ConnectorTo 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 trac monitored (see Figure 1.7).Figure 1.7 – Service End LabelingGrounding 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 trac cabinet.
In this chapter  Mounting the Backplate  Connecting AC Power  Providing System Surge Protection  Terminating SmartSensor 6-conductor Cables2After installation, each SmartSensor Matrix will need to be integrated into the main traf-c cabinet for power and surge protection. is chapter contains information on how to provide power and surge protection to a preassembled backplate that accommodates four SmartSensor Matrix sensors (one for each stop bar of a common four-approach intersec-tion). Note Also available to use are the intersection preassembled 19-inch rack for server racks, the intersection segmented preassembled backplate for easier installation in trac cabinets, and the Click 600 cabinet interface device (which combines all the function-ality of the backplates in one module). Installation procedures for the rack and the segmented backplate will be very similar to the instructions that follow; installation procedures for the Click 600 can be found in Appendix D of this guide.e standard four-approach preassembled backplate is 11 in. (28 cm) wide and 11.5 in. (29.2 cm) high. All wiring on the rack and backplates is done using stranded wires with wire ferrules for screw terminal connections (see Figure 2.1).Connecting Power and Surge Protection 2
22 CHAPTER 2  CONNECTING POWER AND SURGE PROTECTIONFigure 2.1 – Intersection Preassembled BackplateMounting the BackplateUse the following steps to mount the backplate in the trac cabinet:1 Locate the area planned for mounting the backplate. e backplate can usually be mounted on the side panel of a NEMA-style cabinet. 2 Attach the backplate with the U-channel mounting screws. NoteIf you have a 330 series (170/2070 style cabinet) with a 19-inch EIA rack, please con-tact Wavetronix Technical Services for assistance. Wavetronix can provide modified backplates that attach to a 19-inch rack.Connecting AC PowerSince SmartSensor Matrix operates on 10–28 VDC, the standard preassembled backplates provide an AC power conversion option. e backplate includes an AC to DC power con-verter, power surge and circuit breaker.
CHAPTER 2  CONNECTING POWER AND SURGE PROTECTION 23WarningMake sure power to AC mains is disconnected while wiring the AC input. If your in-stallation does not require AC power, you will need to use surplus DC power inside the trac cabinet. In this case, Wavetronix recommends you use the Click 221 (8 A DC surge protector) to protect the backplate and SmartSensor Matrix units from DC surges. See Appendix C for information regarding the Click 221.Figure 2.2 – Connecting AC Power to the Preassembled BackplateUse the following steps to connect power to the AC terminal block on the bottom DIN rail (see Figure 2.2):1 Connect a neutral wire (usually a white wire) to the bottom side of the terminal block labeled “N” for neutral.2 Connect a ground wire (usually a green wire) to the bottom of the terminal block la-beled “G” for ground. (see the Wiring Protective Earth Ground section below).3 Connect a line wire (usually a black wire) to the bottom of the terminal block labeled “L” for line.4 Turn on AC mains power.5 Press the circuit breaker switch on the left side of the top DIN rail to switch power to the backplate. e switch is on if the button is below the level of the device housing; the switch is o if the button is raised above the surface of the housing.6 Verify that DC power is properly regulated by making sure the DC OK LEDs are il-luminated on the Click 201/202/204.
24 CHAPTER 2  CONNECTING POWER AND SURGE PROTECTIONCautionAn authorized electrical technician should install the preassembled backplate. Per-sons other than authorized and approved electrical technicians should NOT attempt to connect the backplate to a power supply and/or trac control cabinet, as there is a serious risk of electrical shock through unsafe handling of the power source. Extreme caution should be used when connecting the backplate to an active power supply.e AC power conversion section of the backplate will come pre-wired as shown in Figure 2.3. e main three components of the AC power conversion section include: Click 201/202/204 AC to DC converter – A Click 201 provides 1 A of power and is capable of powering a single sensor; a Click 202 provides 2 A and can power two sen-sors; a Click 204 provides 4 A and can power four sensors. Click 210 circuit breaker – Interrupts power during overload conditions and provides a convenient way to turn power on and o for the entire system. Click 230 AC surge protector – Helps protect equipment from current surges on the power lines.Figure 2.3 – AC Power ConversionWiring Protective Earth GroundAll connections are surge protected when the protective earth ground is wired to the PE terminal block on the backplate. Normally, the backplate should be mounted to the chassis of the cabinet to provide a ground path. It is strongly recommended that you provide a low impedance protective earth connection.
CHAPTER 2  CONNECTING POWER AND SURGE PROTECTION 25Follow the steps below to provide a low impedance protective earth connection:1 Connect one end of a protective earth ground wire to the bottom of the PE terminal block. A 10 AWG stranded wire is recommended for protective earth ground connec-tions and is also the largest that will t in the terminal block. 2 Connect the other end of the protective earth ground wire to a protective earth screw terminal within the main trac cabinet.Controlling DC Power Distributione Click 210 circuit breakers provide a convenient way to turn power on or o for each sensor independently (see Figure 2.4). To enable or disable DC power to the backplate, switch the main circuit breaker (left side of upper DIN rail); to enable or disable DC power to an individual sensor, switch the individual circuit breaker (left side of each sensor’s set of terminal blocks).Push this button to turn power on or oFigure 2.4 – DC Power DistributionNoteThe switch is ON when the switch button is level with the device housing; the switch is OFF when the switch button is raised above the housing.e four-approach preassembled backplate has 24 VDC power wired from the output of the AC to DC converter into a 5-position screw terminal on the left side of the T-bus (see Figure 2.5). e green T-bus conducts DC power and RS-485 communications from the left to the right side of the modules; the gray T-bus conducts only DC power from the left to the right side of the modules.

However, it is strongly recommended that the sensor be connected to a surge protection device in the main trac cabinet. If you choose not to use surge protection in your main trac cabinet, please contact Wavetronix Technical Services for assistance.When a Click 222 is present, the power and RS-485 serial connections on the T-bus and faceplate are protected from surges on the incoming SmartSensor 6-conductor cables. e Click 222 faceplate has four activity indicator LEDs: PWR – Indicates that the device has power. DC Surge OK – Indicates that DC surge protection is operational.

Each 6-conductor cable has one DC power wire pair, two RS-485 communication pairs, and a drain wire. e service end of the cable connects to plug-in terminals on the preas-sembled backplate (see Figure 2.8).Figure 2.8 – Color Label on Plug-in Terminals
CHAPTER 2  CONNECTING POWER AND SURGE PROTECTION 29NoteDo not strip the service end of the cable until after it has been routed through con-duit. The cable should be one continuous run without any splices.Use the steps below to land the sensor cables:1 After 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 2.8. 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.ere are two measures in place to ensure that the plugs are always returned to their correct terminal block sections.First, for visual conrmation, one part of the plug is blue (see Figure 2.8) and must be visually matched up to a blue terminal block. e location of the blue piece rotates in the dierent plugs and terminal block sections: in the rst, the rst block is blue, in the second, the second is blue, etc.Second, the plugs are keyed (see the blue piece in Figure 2.8) so they will only t into their correct terminal block sections.Wire Color SignalRed (PWR) DC+Black (GND) DC-White with Blue stripe (485+) Control bridge 485+ (port1)Blue (485-) Control bridge 485 - (port 1)White with Orange stripe (485+) Data bus 485+ (port 2)Orange (485-) Data bus 485- (port 2)Bare metal (DRN) DrainTable 2.1 – Cable Wiring Color Code

During real-time operations, up to four channels from each sensor can be sig-naled to a Click 114 or Click 104 (or to a pair of Click 112 cards daisy-chained together).Figure 3.1 – Click 104 (left) and Click 112/114 Rack Cards (right)Contact Closure Communication 3
32 CHAPTER 3  CONTACT CLOSURE COMMUNICATIONNoteSee the Click 100–400 Series User Guide for complete information on how to con-nect and configure the Click 104 DIN rail contact closure module and the Click 112/114 detector rack cards. Each SmartSensor Matrix could potentially use up to 16 channels using a combination of Click 104/112/114 contact closure modules. is means that a standard four-approach stop bar detection system can be accommodated by a 64-channel detector rack.e Click 112/114 cards can be congured using DIP switches on the circuit board, the front panel menu on the faceplate or Click Supervisor. e Click 104 can be congured using the rotary switch, the front panel menu on the faceplate or Click Supervisor.Using the Click 112/114 DIP Switchese DIP switches allow you to program the baud rate and input mapping using the hard-ware. If the Click 112/114 cards are programmed using the DIP switches, the settings can be viewed, but not modied, using the front panel menu or Click Supervisor. If you are planning to use either the front panel menu or Click Supervisor to program the device settings, then you will need to rst make sure that the DIP switches are set to al-low for software conguration; to set this, simply make sure that all relevant switches are turned o (see Figure 3.2). 1435678123456782OnOMakes channel group selection software configurableChannel GroupBus 1 Bus 2S4 S5Input Mapping Switches Baud Rate SwitchesFigure 3.2 – DIP Switch Setting for Software Configuration Mode (left)ere is no need to change the baud rate of the Click 112/114 cards from the factory de-fault of 9600 baud. e settings for the input mapping, however, will need to be set. is process is explained in the following sections.
CHAPTER 3  CONTACT CLOSURE COMMUNICATION 33NoteAn advantage of using the DIP switches for configuration is that if you ever need to replace a Click 112/114, you can simply set the DIP switches on the new card to match the pattern of the DIP switches on the card you are replacing, then slide the new one into the same slot in the detector rack. Click 114 Input Mapping DIP Switch SettingsOn a Click 114, channel group 1 comprises input channels 1–4. When this channel group is selected; sensor channel 1 will be mapped to output channel 1; sensor channel 2 will be mapped to output channel 2; sensor channel 3 will be mapped to output channel 3; and sensor channel 4 will be mapped to output channel 4.Use Figure 3.3 below to set the DIP switch settings to select channel group 1:1234567812345678OnOClick 114 – Selects Matrix channels 1 through 4 for outputChannel GroupBus 1 Bus 2S4 S5Input Mapping Switches Baud Rate SwitchesFigure 3.3 – Click 114 DIP Switch SettingsClick 112 DIP Switch SettingsOn a Click 112, channel group 1 comprises input channels 1 and 2, where sensor channel 1 will be mapped to output channel 1 and sensor channel 2 will be mapped to output chan-nel 2. In order to map sensor channel 3 to output channel 1 and sensor channel 4 to output channel 2, you will need to select channel group 2. If you are using two Click 112 devices, you will need to set the DIP switches dierently for each card and daisy-chain the cards together using bus 1. Figure 3.4 below shows how to set the DIP switches on the Click 112 card on the left. is will select Matrix output channels 1 and 2 for output.

Using the Click 104 Rotary Switche rotary switch is located on the lower part of the faceplate and can be used to change the channel input mapping. e switch can be twisted by inserting a small screwdriver into the arrow slot. If you use this switch to set the channel input mapping, you won’t be able to use the Click Supervisor software or the front panel menu to change this particular parameter (although you will still be able to use them to change other parameters). If the switch is set to 0, the device is in Software mode. is means that all parameters are set by the front panel menu or Click Supervisor. If the switch is set to any other number, the device is in Hardware mode, meaning that the channel input mapping is set by the rotary switch. e Click 104 has four output channels; if you need more than this, you’ll need to use mul-tiple devices daisy-chained together.
CHAPTER 3  CONTACT CLOSURE COMMUNICATION 35As shown in the table below, the outputs are mapped sequentially—that is, they can only be mapped in numerically ordered groups of four (1–4, 5–8, etc.). If you set the switch to 3, for 9–12, then sensor channel 9 would be mapped to output 1, sensor channel 10 would be mapped to output 2, sensor channel 11 would be mapped to output 3, and sensor channel 12 would be mapped to output 4.Switch Channels0 Software mode1 1–42 5–83 9–124 13–16517–206 21–247 25–288 29–32933–36Table 3.1 – Click 104 Rotary Switch Channel Input Map SettingsAttaching and Programming the Click 112/114 Use the following steps to set up the contact closure rack cards for each sensor:1 Make sure the DIP switches are set according to Figure 3.3 for a Click 114 and Fig-ures 3.4 and 3.5 for Click 112 cards.2 Power all the cards by plugging them into the detector rack. Figure 3.6 – Wiring the Click 112/114 Rack Cards3 Connect a 6-ft. (1.8-m) patch cord from the Click 222 RS-485 A port to a bus 1 port on the appropriate rack card (see Figure 3.6).
36 CHAPTER 3  CONTACT CLOSURE COMMUNICATION4 Connect a 6-ft. (1.8-m) patch cord from the Click 222 RS-485 B port to a bus 1 port on another rack card.5 If you are using Click 112 cards, use an 6-in. (15-cm) patch cord to share bus 1 be-tween cards dedicated to the same sensor. Also, congure one card to use Matrix chan-nels 1 and 2 and congure the other card to use Matrix channels 3 and 4. If you have more than two sensors in your system, repeat steps 2–4 to connect bus 1 for all remain-ing rack cards.6 Connect a 5-ft. (1.5-m) patch cord from one of the Click 222 bridge ports to bus 2 of the rack cards.7 Use the 6-in. (15 cm) patch cords to create a daisy-chain that shares bus 2 between all of the rack cards. Bus 2 will be used for device conguration.Click 112/114 LEDsOnce you have completed the wiring, check the Menu Level 1 LEDs, which have both menu-indicating and general status–indicating functions. e list below contains informa-tion on the general status–indicating functions of the LEDs: PWR (red) – Indicates the device is powered. PU (blue) – is LED is not associated with any general status function and should remain o while the card is in normal operating mode. TD (green) – Indicates the card is transmitting serial communication. RD (yellow) – Indicates the card is receiving serial communications.e red LED should be on, showing the card is powered and operating normally.e list below contains additional information about the rest of the LEDs: Detection Channel LEDs (red) – Indicates when a call is placed on the corresponding contact closure output channel. Menu Level 2 – Used for the conguration menu that is activated using the Mode switch. General Status (Menu Level 1) – In addition to the functions listed above, these are used to cycle through and select options from the front panel menu.
CHAPTER 3  CONTACT CLOSURE COMMUNICATION 37Detection ChannelMenu Level 2Menu Level 1Mode SwitchFigure 3.7 – Click 112/114 MenuNormally, a SmartSensor Matrix sensor will send 10 contact closure messages each second. If a rack card does not receive communications from a sensor within 10 seconds, the rack card will go into fail-safe mode and all of the contact closures will be activated and the cor-responding detection channel LEDs on the faceplate will turn on. Attaching and Programming the Click 104Use the following steps to set up the DIN rail contact closure module for each sensor:1 Mount the Click 104 on a DIN rail over a T-bus connector. is connects the device’s control bus (bus 2) to the installation’s shared communication bus; you can connect your computer to another device on this shared bus, such as the Click 305 USB con-verter, to access the Click 104 to congure it using Click Supervisor. Mounting the Click 104 on the T-bus also connects it to the power source.Figure 3.8 – Wiring the Click 104 Module2 Send detection data to the data bus (bus 1). Connect a Click 222 to the Click 104 by connecting jumper cables from the RJ-11 jacks on the faceplate of the Click 222 to the RJ-11 jacks on the faceplate of the Click 104 (see Figure 3.8).
38 CHAPTER 3  CONTACT CLOSURE COMMUNICATION3 If needed, daisy-chain multiple Click 104 devices together by utilizing both RJ-11 jacks on each device’s faceplate.Click 104 LEDse front panel of the device features a push-button and three banks of LEDs for on-device conguration and monitoring. e rst bank of LEDs, labeled Channel, displays the state of the contact closure outputs (see Figure 3.8). 1 2 3 4ChannelMenuPWR OK TD RDFigure 3.9 – Click 104 LEDse two lower banks of LEDs, labeled Menu, and the push-button, labeled Mode Switch, are used for navigating through Menu mode. e lower bank of LEDs will be referred to as Level 1 and is used in selecting menu op-tions. e upper bank will be referred to as Level 2 and is used in conguring the menu op-tions.

(Pressing and hold-ing again will resume cycling through menu options.)3 Quickly press and release the mode switch to select the current menu option. Once it’s selected, the Level 2 LEDs will start to let you congure the options for the selected

Many intersections will not have eight phases, and in some cases they may not even follow the NEMA conven-tion. Check the plans in the trac signal cabinet to verify how the phases are numbered at each intersection.25164783Figure 3.11 – Standard NEMA 8-phase Number SchemePhases 1, 2, 5 and 6 are often used for the “main” street, and phases 3, 4, 7 and 8 are often used for the “side” street as shown in Figure 3.8.NoteChapter 10 contains a section about Rack Card Tools which explains how the channel-to-phase mapping can be verified with or without the sensors installed.Since each Matrix sensor often detects both the left-turn phase and the through-move-ment phase for a single approach, the associated rack card will have often have channels that correspond to one of the following phase (ф) pairs: ф2 and ф5; ф6 and ф1; ф4 and ф7; ф8 and ф3.
40 CHAPTER 3  CONTACT CLOSURE COMMUNICATIONNEMA TS2, 2070 and other advanced trac cabinet systems usually allow software pro-gramming of the detector card channel outputs to trac phases via a channel-to-phase mapping grid in the controller menu. Figure 3.9 illustrates how the detector channels 1 to 16 of a NEMA TS-2 rack can be assigned to the standard eight phases using four Click 114 cards. e rack card slots are numbered across the top and the controller’s detection channels are represented by the gray labels C1–C16.C1↓Φ1C2↓Φ6C3↓Φ6C4↓Φ6C5↓Φ5C6↓Φ2C7↓Φ2C8↓Φ2C9↓Φ3C10↓Φ8C11↓Φ8C12↓Φ8C13↓Φ7C14↓Φ4C15↓Φ4C16↓Φ4Slot 1 Slot 2 Slot 3 Slot 4 Slot 5 Slot 6 Slot 7 Slot 8Figure 3.12 – NEMA TS-2 Type 1 Rack Channel to Trac Phase ExampleIn Figure 3.9, four channels are used from each SmartSensor Matrix. In this example, channel 1 from the rst sensor is mapped to trac phase 1 (left-turn phase on main street). Channels 2, 3 and 4 from the rst sensor are mapped to trac phase 6. is represents a case where detections from three through-movement lanes are brought in separately. is type of lane-by-lane detection can be benecial in some situations. Wavetronix typically recommends the use of 4-channel cards because it oers greater exibility of signaling contact closures.NoteWith NEMA TS1 and other legacy systems, the programming is often done via a wir-ing panel on the side of the controller cabinet. With wired systems, you will need to verify that the wiring on the detector programming panel provides the proper map-ping from the rack channel outputs to the controller input wires dedicated for ф1–ф8 detector calls.

Making a virtual connection can be useful for the following reasons: To view a saved sensor setup le To play back previously logged trac To demonstrate functionality for dierent trac applications
CHAPTER 5  COMMUNICATION 59 To review how the software worksUse the following steps to make a virtual connection:1 Click the Communication button.2 Select the Virtual tab (see Figure 5.9).Figure 5.9 – Virtual Connection Screen3 Select or create a virtual sensor le (.vsf ) by clicking the magnifying glass icon.4 Click the Search button. is may take up to 30 seconds while the sensors on your virtual control bus are discovered and listed. (You can click Cancel if the sensor of interest has already been listed.)5 Click on the desired row from the list to select a sensor. 6 Click the Connect button. When a connection is established you will be directed back to the home page.Virtual Sensor FileSince a virtual connection is not made to an actual sensor, a virtual sensor le (.vsf ) is used to save the conguration settings much like an actual sensor’s ash memory. SSMM comes with default virtual les that you can see once you click the Search button. If you create your own virtual sensor le, you will have to nd it in the virtual les directory by clicking the magnifying glass icon under the Virtual Sensor Files Location heading.NoteWhen you are connected using a virtual sensor file, changes that would normally be saved to a sensor’s flash memory will automatically be saved to the virtual sensor file.
60 CHAPTER 5  COMMUNICATIONVirtual sensor les can be converted to sensor setup les and can be restored to an actual sensor; sensor setup les that have been backed up from a sensor can also be converted to virtual sensor les. To convert a sensor setup le to a virtual sensor le, make a virtual connection and then use the Restore Sensor Setup tool in the Tools menu. To convert a virtual sensor le to a sensor setup le, use the Back-up Sensor Setup tool.NoteTo configure channels for a future installation, connect using a virtual connection, create a virtual sensor file and then back up the configuration settings that you cre-ated. After the file is successfully backed up, the virtual sensor file will change to a sensor setup file and can be restored to any sensor in the field.When a connection is made to the SmartSensor Matrix, the main menu will appear and all conguration options will become available (see Figure 5.10).Figure 5.10 – Main Menu (Connected)Viewing Connection Information Once connected, you can view additional information about the connection you have es-tablished by clicking on the moving arrows icon on the top right of the main menu page or on the bottom right of the Communication screen (see Figure 5.11). ese arrows are only visible when there is an established connection.
CHAPTER 5  COMMUNICATION 61Figure 5.11 – Connection Info ScreenBelow is a list of the information available on the Connection Info screen: Status – Shows that you are connected. Sensor – Shows the subnet and sensor ID. Type – Shows the type of connection. Duration – Shows how long you have been connected. Failures – Shows the amount of failures during the connection, the percentage rate of failure and a link to the communication error log.Communication Error Log e error log contains all errors stored in the sensor’s memory buer. If you are having trouble connecting, using the error log may be helpful in the troubleshooting process. If you continue having trouble, save the error log le and contact Wavetronix Technical Services.NoteThe error log is cleared every time you close SSMM, so if you need to save the file, do so before shutting the program down.Click the View Error Log link to view the communications error log (see Figure 5.12). e error log can also be accessed by clicking on the Error Log icon at the bottom of the Communication screen.
62 CHAPTER 5  COMMUNICATIONFigure 5.12 – Error LogUpgrading the Sensor’s Embedded SoftwareAfter clicking the Connect button, the software will check to see if your software version matches the version of the sensor’s embedded software. If a discrepancy is detected, the Version Control screen may appear asking you to install rmware upgrades (see Figure 5.13). If you think you have reached this screen in error, clicking the Recheck button will have the software retry and ensure that there has not been a communication issue. Click-ing the Details button will display the current sensor and software information. Click the UPLOAD FIRMWARE button to upgrade the software.Checking the Upload to all sensors checkbox will broadcast the upgrade to all the sensors on the control bridge. Check the Disable fast pacing checkbox if you are connected using Bluetooth or other devices with a slow connection speed (see Figure 5.13). Figure 5.13 – Sensor’s Embedded Software Upgrade (left) and Details Table (right)
CHAPTER 5  COMMUNICATION 63Click the Details button to view the rmware versions of both the SSMM software and the SmartSensor Matrix.Once the Version Control screen appears, you can do one of the following: Upgrade the sensor’s embedded software by clicking the UPLOAD FIRMWARE button. Click the Close button and continue the conguration process. Find the version of SSMM software that is compatible with the sensor’s embedded software.NoteClicking the Close button and continuing configuration without upgrading may cause problems with functionality.If any row is highlighted in red, the rmware upgrade may need to be installed. Compare the sensor number with the SSMM number in the Digital row of the details table. If the SSMM rmware version date is more recent than the sensor rmware version date, the newer rmware will need to be installed; if the sensor’s rmware date is more recent than the SSMM rmware version date, a warning will appear notifying you that older rmware will be uploaded to the sensor (see Figure 5.14). Figure 5.14 – Sensor Firmware Downgrade (left) Back Up Configuration (right)If the downgrade message appears, it means that the sensor rmware is newer than the ver-sion of SSMM that was used to connect to the sensor. e newest version of SSMM can be downloaded from www.wavetronix.com.If you are upgrading from certain versions of SSMM, the upgrade may cause you to lose
64 CHAPTER 5  COMMUNICATIONyour sensor conguration. Follow the steps in the back up message to back up your sensor’s conguration. NoteIf you are upgrading the software, it is always a good idea to back up your sensor con-figuration. There is always a chance that the sensor conguration could be lost after upgrading. You can create a back up file by going to the Tools screen (see Chapter 10).Click the UPLOAD FIRMWARE button to install the rmware embedded in SSMM onto the SmartSensor Matrix. e Recheck button will query the sensor to see if the rm-ware bundled in SSMM is dierent than the version running on the sensor.
In this chapter  Sensor Settings Screen  Sensor Info Screen6Click the Sensor Settings link on the main menu to change and save settings on the sensor.General Sensor Settingse General tab of the Sensor Settings screen allows you to change the sensor description, RF channel, wash-out time, and other settings (see Figure 6.1).Figure 6.1 – Serial Settings WindowSensor Settings 6
66 CHAPTER 6  SENSOR SETTINGSe General tab contains the following elds: Serial Number – Contains the sensor serial number and cannot be edited. Sensor ID – Contains the ID used to uniquely identify all sensors on a multi-drop bus. is ID is the last seven digits of the sensor’s serial number and cannot be edited. Description – Allows you to enter a description for each sensor. Limited to 64 char-acters. Location – Allows you to enter the intersection location of the sensor. Limited to 64 characters. Approach – Allows you to enter information about the direction of trac the sensor is detecting (e.g. NB, SB, EB, WB). Limited to 32 characters. RF Channel – Lets you set which one of the eight radio frequency channels the sensor is using. Using multiple sensors in close proximity will require each sensor to be set to a dierent RF channel (see the introduction for more information about mounting the sensor). Sensor Height – e height of the sensor in feet. is value aects the sensor’s detec-tion algorithms. Entering an approximate height measurement for the sensor allows detections to be placed correctly on the roadway. Wash-out Time – Used to set the time the sensor has to see a tracker before it gets washed out into the background. Units – Allows sensor height, zone dimensions and road objects to be viewed in metric mode rather than standard units.Comm Sensor Settingse Comm tab allows you to change the response delay, and other settings (see Figure 6.2).Figure 6.2 – Comm Tab Response Delay – Used to congure how long the sensor will wait before responding to a message received. is is useful for some communications devices that are unable
CHAPTER 6  SENSOR SETTINGS 67to quickly change transmission direction. e default value is 10 milliseconds. is value can be selected for both of the sensor’s ports independently.NoteIn many cases, SSMM will be connected over port 1. A green arrow is used to show the port over which SSMM is connected to the sensor. During troubleshooting or other special cases, you may want to connect to the sensor over port 2. Port 2 is connected to the orange RS-485 wire pair and is typically used for detection calls. Data Push – Data can be pushed over port 1, port 2 or both. To disable data push, select None. In many cases, data push will only occur over port 2.If you would like to change which port is used to push data, please contact Wavetronix Technical Services rst, as changing this setting can aect how the sensor, and other devices connected to it, are wired. NoteIf for some reason SSMM connects over the same port that SmartSensor Matrix is using to push data, the software will continue to poll the sensor for detection call messages. This will help keep the intersection operating normally during the con-figuration process. Source – In normal use, the source is always the radar antenna. However, in some cases, other sources may be used for demonstrations or evaluations. When the source is switched to Diagnostic, the antenna is no longer used. Instead, a predetermined sequence of trac will appear. Sensor Info ScreenSome of the Sensor Settings information can be viewed on the Sensor Info screen. After searching for sensors, select a sensor from the list and either click on the sensor icon in the upper right corner of the Communication screen or click again on the sensor row and the Sensor Info screen will appear (see Figure 6.3).

In this chapter  Display Options  Menu Bar  Automatic Configuration  Manual Configuration7After Sensor Settings, the next option available from the main menu is Sensor Setup. When you click this option, the rst screen that appears is Lanes & Stop Bars.e Lanes & Stop Bars screen shows the sensor’s 100-ft. (30.5-m), 90° degree view and provides automatic and manual controls to quickly and easily congure the sensor to the roadway. e sensor’s view has the appearance of a baseball ineld with the sensor icon shown at the position where home plate would be (see Figure 7.1).Figure 7.1 – Lanes & Stop Bars TabLanes & Stop Bars 7
70 CHAPTER 7  LANES & STOP BARSVehicle detections are represented by tracks (a series of dots) along the sensor’s view. e vehicle tracks show where the sensor is detecting trac and will later help you congure lanes. Vehicle track history can be cleared from the screen by clicking the Clear Tracks button below the sensor view.NoteVehicle tracks are not constrained to lanes, even after you have saved a lane configu-ration to the sensor. Display Optionse Lanes & Stop Bar tab has the following display options: Edit Area Edit Area with Saved Conguration Overlay Edit Area with Automatic Conguration OverlayEdit Areae edit area is where manual changes to the sensor’s conguration are made (see Figure 7.2). e changes you make in the edit area will only be saved if you click on the Save Con-g button or click on another tab. Edit AreaFigure 7.2 – Edit AreaYou can copy elements from the saved and automatic conguration, which will be described later.
CHAPTER 7  LANES & STOP BARS 71e Edit Area also contains the approach name in a small window outside of the sensor’s view (see Figure 7.3) If needed, click on the name box to see the entire approach name. is allows you to always know which approach is being congured. e approach name can be edited in the Sensor Settings window.Figure 7.3 – Approach NameSaved Configuration Overlaye Saved Conguration overlay shows everything that has been saved to the sensor (see Figure 7.4). e purpose of this feature is to compare what is currently saved to the sensor with the changes you are making in the edit area. To show or hide this overlay, click the Saved Cfg button.Figure 7.4 – Saved Configuration OverlayAutomatic Configuration Overlaye Automatic Conguration overlay shows lanes and stop bars that have been automati-cally discovered (see Figure 7.5). To show or hide this overlay, click the Auto Cfg button.
72 CHAPTER 7  LANES & STOP BARSFigure 7.5 – Automatic Configuration OverlaySmartSensor Matrix is constantly running the auto-conguration process in order to nd undiscovered lanes and stop bars. During this process, lanes will appear in the Auto Cfg overlay. You will need to select and capture auto-congured lanes in order to save them to the sensor (see the Capturing Lanes and Stop Bars section below). Wait at least 2–3 cycles of the intersection to accurately detect the lanes and stop bars.Capturing Lanes and Stop BarsLanes that appear in the Saved Conguration Overlay or in the Automatic Conguration Overlay can be captured by clicking on them. Once a lane is captured, it becomes part of the edit area. Captured lanes are only copied to the edit area and are NOT saved to the sensor until after clicking on the Save Cong button.To capture lanes:1 Select a lane by clicking on it once.2 Click on the lane a second time to bring up the Capture window (see Figure 7.6).3 Click on the Capture Lane button to capture the selected lane. If you want to capture all the congured lanes, click the Capture All button.Figure 7.6 – Capture Window
CHAPTER 7  LANES & STOP BARS 73NoteIf a stop bar is found for a lane during the auto-configuration process, it will be cap-tured with the lane. Menu Bare menu bar at the bottom of the screen allows you to perform a variety of operations during sensor conguration. Click the button at the right side of the menu bar to open a window that shows descriptions for the various menu icons (see Figure 7.7).Figure 7.7 – Sensor Setup Menu Windowe Menu Bar contains the following options: To Main Menu – Returns you to the main menu. Save Config – Saves the lanes and stop bars to the sensor. Undo Last Edit – Undoes the last change in the edit area. Clear Edit Area – Deletes all lanes from the edit area. Move Sensor – Moves the sensor to a dierent corner of the edit area and rotates the view accordingly. Restart/Reboot – Gives you the option to restart automatic conguration or reboot the sensor. Edit Thresholds – Allows you to edit the sensor’s thresholds. Pause Trac – Suspends or resumes movement of vehicle tracks on the screen.Saving the Configuration After automatic and manual conguration is complete, click the Save Cong button to save the changes to the sensor. If you attempt to leave the Lanes & Stop Bar view before saving your changes, the following prompt will appear (see Figure 7.8).
74 CHAPTER 7  LANES & STOP BARSFigure 7.8 – Save Changes DialogMoving the Sensor View e SSMM software shows the position of the SmartSensor Matrix and the view is drawn from the perspective of the sensor. e sensor’s default position is in the bottom-left corner of the display. If the perspective in the software does not match your perspective of the roadway, click the Rotate View button until the sensor position matches the approach you are conguring.NoteMoving the sensor in the software will have no eect on the sensor’s performance. Its purpose is to facilitate the configuration process.Restarting Auto Lane Config/Rebooting the Sensor Restarting the automatic lane conguration will erase any auto-conguration information that may have been gathered and will start the auto-conguration process over again.Rebooting the sensor will also erase any auto-conguration information, but in addition will clear and recongure the sensor thresholds. Follow the steps below to restart the automatic lane conguration process or reboot the sensor:1 Click the Restart/Reboot button and the Restart or Reboot window will appear (see Figure 7.9).2 Select the appropriate radio button and click OK.Figure 7.9 – Restart or Reboot Window
CHAPTER 7  LANES & STOP BARS 75NoteAfter you have mounted and aligned the sensor, you should always reboot the sensor so that thresholds can adjust to the current view.Editing Thresholds You should only edit the Matrix thresholds under the direction of Wavetronix Technical Services.WarningIf you believe that you need to adjust the thresholds, please call Wavetronix at 801-734-7200 for assistance.1 Click on the Edit resholds button. is will turn the sensor’s view green and allow you to change the sensitivity of certain areas in the view.2 Click anywhere within the sensor’s view and the Sensitivity window will appear (see Figure 7.10).Figure 7.10 – Sensitivity Windowe Sensitivity window contains the following options: Adjust All – Allows you to edit all of the sensor thresholds. Adjust Region – Allows you to adjust thresholds in a selected region of the sensor view. Zoom In – Allows you to zoom in and change thresholds of selected areas in the sensor view (see Figure 7.11). Reset Region – Allows you to reset only a selected region of thresholds to default set-tings. Reset All – Allows you to reset all the sensor thresholds to default settings.

84 CHAPTER 8  ZONES & CHANNELSEditing Zones Click the Edit Zone button to adjust the currently selected zone. An entire zone can be moved by clicking and dragging or by using the arrow buttons on the Edit Zone window (see Figure 8.5). Zones can overlap each other.Figure 8.5 – Edit Zone WindowPlacing AutoZones Click the Place Auto Zones button if you would like to replace your manually congured zones with auto zones. Placing auto zones requires you to insert the distance from the stop bar and also the auto zone width (see Figure 8.6). Clicking Yes will add a zone to each automatically congured lane. Figure 8.6 – Placing Auto Zones PromptIf zones are too long for the SSMM view, the zones will be cropped so that the entire zone can be seen. For more information on auto zones, see the auto zone information at the beginning of this chapter.NotePlease note that all existing zones will be removed before new zones are placed au-tomatically.Channel Typeere are three dierent types of channels to choose from: Normal, Counting and Pulse.
CHAPTER 8  ZONES & CHANNELS 85Normal Channele normal channel detects presence in the zone. is means that as soon as the leading edge of the vehicle breaks the plane of the leading edge of the zone, the channel will be activated (see Figure 8.7).Channel LEDPulseChannel LEDChannel LEDFigure 8.7 – Normal ChannelIf there are no delay or extend settings, the zone will remain activated until all cars have exited the zone. Counting ChannelA counting channel counts each vehicle that passes through the zone. e channel is acti-vated once the middle of the vehicle crosses the leading edge of the zone (see Figure 8.8).NoteIf you use a counting channel, you need to position the zones so that the vehicle is detected and tracked before it arrives at the zone. Also, fast-traveling vehicles may not be counted as accurately as slow-moving vehicles.Channel LEDPulseChannel LEDChannel LEDFigure 8.8 – Counting ChannelOnce you select a counting channel type, the delay and extend settings will be disabled.
86 CHAPTER 8  ZONES & CHANNELSPulse ChannelA pulse activates the channel for a very short period of time once the front edge of the ve-hicle crosses the leading edge of the zone (see Figure 8.9). You can congure how long you would like the pulse to be by changing the pulse channel width setting (see Figure 8.13). A new pulse will only be sent after a car enters a zone when the zone is empty. Channel LEDPulseChannel LEDChannel LEDFigure 8.9 – Pulse ChannelEven though the zone stays activated, the contact closure call will only stay on for the time specied in the pulse channel width setting. You can verify the duration of the pulse chan-nel calls by viewing the virtual LEDs in the SSMM software. Once you have selected the pulse channel type, the extend setting will be disabled. NoteA pulse channel may be dicult to view in the SSMM software. The default pulsed channel width is 200 ms. To better view the pulse channel activation, increase the pulsed channel width in the output settings window (see the Output Settings sec-tion below).Mapping Zones to ChannelsAfter the zones are placed, the zones must be mapped to output channels. Channel map-ping is described in the following sections.Zone/Channel Map e Zone/Channel map allows you to map or un-map zones to channels (see Figure 8.10). To map a zone to a channel, determine which zone you want to map to which channel and click on the gray indicator in the Zones/Channels table. A zone is mapped to a channel only if the corresponding indicator is green. To see Channels 9–16, click and drag anywhere inside the table.
CHAPTER 8  ZONES & CHANNELS 87Figure 8.10 – Zone/Channel Map WindowEach channel column contains channel number and channel type (N=normal, C=count, P=pulse). Click on the individual zones in the zone column to highlight the zones in the edit area. Editing Channels e Edit Channel button will allow you to choose the channel type, map/un-map zones to a selected channel, and change delay/extend settings (see Figure 8.11). Click on the Z1–Z16 indicators to map a zone/zones to the channel (only the congured zones will be visible). Click on the channel indicator in the top-left corner or the Edit Channel button to quickly cycle through channels.Figure 8.11 – Edit Channel Windowe Edit Channel window also allows you to do the following: AND/OR – Channels support AND and OR logic for all zones. Using the AND logic means that all the selected zones have to be active for the channel to be triggered; the OR logic means that any activity in any zone will trigger the channel. Click on the AND or OR button to change the logic. Delay/Extend Settings – Delay and extend settings can be viewed and then edited for a selected channel. e channel delay is used to ignore alert outputs that are shorter than the specied delay time. e extend feature is used to continue a channel output after the required conditions have been met. e delay and extend settings will be disabled for all counting channels and the extend setting will be disabled for all pulse channels.To edit the extend and delay, click anywhere in the white box with the D and E, and the corresponding box will appear (see Figure 8.12). Manually edit or use the up/down buttons to change the delay/extend settings.
88 CHAPTER 8  ZONES & CHANNELS Figure 8.12 – Output Settings (Normal, Counting, Pulse) Detector Input – e Detector Input number provides a way for you to map inputs to the intersection phase in the controller. By default, the Detector Input will be set to “00;” if the input is left at “00,” then it is unassigned. is setting is for reference purposes only and does not actually change the sensor. Phase – Since the SmartSensor Matrix is capable of monitoring more than one phase, this setting allows you to enter the phase number that most closely represents the phase the sensor is monitoring. By default, the Phase will be set to “00;” if the phase is left at “00,” then it is unassigned. is setting is for reference purposes only and does not actually change the sensor. Channel Type – is drop-down list allows you to select the type of channel (Normal, Counting or Pulse). A normal channel is presence detection; a counting channel is a special pulse based on counting algorithms; and a pulse channel is a generic pulse based on zone presence.Output Settings e extend and delay settings can also be specied using the Output Settings button. is button will open a window that will allow you to select individual channels to edit and also to specify the minimum pulse width and pulsed channel width (Figure 8.13). e minimum pulse width is the minimum duration a presence detection will be signaled via the contact closure rack cards. e pulsed channel width is the duration the contact closure message lasts for a pulse or counting channel. All output settings are specied in seconds.Figure 8.13 – Output Settings Pop-up
CHAPTER 8  ZONES & CHANNELS 89e dashes in the table mean that those particular settings are disabled due to the selected channel type. Double click on any channel row to change the output settings for that channel.Measuring Zonese SSMM software contains a feature that allows you to see how large a zone is as well as a number of other distance measurements. Click on the ruler icon at the top of the Zones & Channels window and then click on the zone you would like to measure and the zone’s dimensions will appear (see Figure 8.14).Figure 8.14 – Zone MeasurementsFlagsA red and blue ag will also appear once a zone is selected. ese ags can be used to measure the distance from that zone to anywhere in the edit area. ese ags will be saved to the sensor. Two additional ags are also available near the ruler icon. ese ags can be dragged any-where on the edit area and used to measure anything in the sensor’s view (see Figure 8.15). ese ags will NOT be saved to the sensor.

To verify lane conguration and channel mapping, click on tab 3. is will bring up the Verication window (see Figure 9.1).Figure 9.1 – Verification ViewIn the Verication window, vehicle detections will appear as light blue rectangles. e ex-tent of these detections will vary based upon the length of the detected vehicle and the length of queued trac.Verification 9
92 CHAPTER 9  VERIFICATIONVehicle detections in a stopped queue are represented by a stationary light blue rectangle. Channel IndicatorsWhen detections enter a zone, they will cause the indicators for the channel mapped to that zone to turn red. To see the zones mapped to a particular channel, select that chan-nel by clicking on its indicator (see Figure 9.2). Active zones for the selected channel will be red; inactive zones for the selected channel will be gray. Click on the yellow button on either side of the channel indicators to see channels 9–16.Figure 9.2 – Channel VerificationNoteOnly the zones for selected channels will appear. If zones are not mapped to any channel, they will not be seen in the Verification window.To see the delay/extend, logic and detector input/phase settings for a single zone, click and hold on a channel indicator and the following window will appear (see Figure 9.3).
CHAPTER 9  VERIFICATION 93Figure 9.3 – Delay and Extend Zone SettingsWhen vehicles stop before and after a zone, the stopped vehicle queue is extended to ll the space between the two vehicles. is ensures that a queue of vehicles that extends in front and behind a zone will always activate the zone even if the vehicles are not directly over it (see Figure 9.4).StoppedVehicleStoppedVehicle Queue ExtensionStopped VehicleFigure 9.4 – Two Vehicles Stopped With a Zone in Between If a vehicle stops within 30 feet of the stop bar, then the stopped vehicle queue will be ex-tended to the stop bar. is ensures that a vehicle will activate a zone even if it stops behind the zone (see Figure 9.5).Stopped VehicleQueue ExtensionStoppedVehicleFigure 9.5 – A Vehicle Stopped Behind the Stop BarVerification Menu BarAs on the Edit Lanes & Stop Bar screen, you can use the menu bar to save a conguration,

Choose a destination, type in a lename for your new backup and click OK, then click the Back-up Sensor Setup button.NoteThe backup will appear as an .mxc file. While this file can be opened as a text file by using Notepad, do not edit the file, as it will change the settings you backed up.e restore function allows you to restore a set of sensor settings you have backed up. To restore, click on the magnifying glass icon in the Restore File section. Select the backup le you wish to restore and click OK, then click the Restore Sensor Setup button.WarningRestoring sensor settings will cause you to lose the settings previously on the sensor, unless they are backed up.To restore the sensor to factory defaults, click the Restore Factory Setup button on the bottom of the screen.
CHAPTER 10  TOOLS 97Rack Cards ToolsAccess tools for working with rack cards and other contact closure devices by clicking the Rack Card Tools button on the Tools screen when a sensor connection is NOT active (see Figure 10.3).Figure 10.3 – Rack Card Toolse Rack Card Tools screen allows you to verify that you have the correct channel mapping into the trac controller, without being connected to a sensor. Serial data messages sent by the rack card tool reach the rack cards via a T-bus and the patch cord connections from the Click 222 control bridge to the contact closure cards. Since this tool can be used without a sensor, it can reduce the amount of time spent on-site when installing a SmartSensor Matrix system. You can use the rack card tool to verify rack card connections while cable is being pulled through conduit or the sensors are being installed. NoteWhen used with SmartSensor Matrix, the rack cards should be configured to com-municate at the default 9600 bps. If you are having communication issues, you may want to verify that the rack cards are configured to communicate at 9600 bps.Using the Rack Card ToolTo search for Click 112/114 rack cards or a Click 104 contact closure device using the rack card tool:1 Click on the Settings button and select the correct communications port and baud rate (see Figure 10.4).
98 CHAPTER 10  TOOLSFigure 10.4 – Rack Card Tool Serial Settings2 After you have entered the correct settings, close the Serial Settings window and click the Search button.3 Once a list of devices appears, click on the desired row. You can identify a device by its ID, Device, Description or Location elds. If you would like to communicate to all the devices, select All Rack Cards in the device column. Statuse Status eld indicates whether the rack card is operating normally or whether it is in fail-safe mode. If the device is in fail-safe mode, the text message may help you understand why the device is in fail-safe. For example, if the text reads “Failsafe Initializing,” this in-dicates that the rack card has never seen any detection call messages since it was rebooted. If the message reads “Failsafe Timeout (No Data),” this indicates that the rack card was previously receiving detection calls, but hasn’t received any in the last 10 seconds or more. e message will always say "Timeout: (No Data)” when you are connected to the Rack Card Tools. Firmware Versione Firmware Version eld lists the version of the rack card rmware. When you would like to refresh the status of these elds, click the associated Refresh button. If you are com-municating with all devices, the status and rmware version elds are not applicable (N/A).Signal Cards SwitchYou can use the Signal Cards toggle switch to help single out devices. When the switch is ON, all main menu LEDs on the selected devices will begin ashing. If you have selected All Rack Cards, then the main menu LEDs of every card connected on the bus will begin ashing.
CHAPTER 10  TOOLS 99Channel Outputs Switche Channel Outputs toggle switch and 1–16 checkboxes are used to help assist in testing of the rack card outputs. If the Channel Outputs switch is ON, all the selected channel outputs on the Click 112/114 rack card or Click 104 contact closure device will be active. e LEDs that indicate an ac-tive output channel will light up accordingly. An output will only be active when the cor-responding box is checked. NoteIt is recommended that you disable pushing by sensors or disconnect the detection call bus patch cord for each sensor before using this tool. Otherwise, the rack card may be receiving conflicting calls on its other bus.e Channel Outputs switch can be very helpful in verifying the I/O channel mapping from the rack card outputs to the trac controller inputs. By sequentially checking boxes 1–16, you should be able to quickly verify the mapping of each channel, even in the absence of trac.Tracker LoggingAccess the Tracker Logging tool by clicking on the Tracker Logging button on the Tools screen. is tool will allow you to log vehicle detections as they are tracked through the sensor’s view (see Figure 10.5). is tool can be used to record trackers and replay them at a later time for demonstration purposes.Figure 10.5 – Tracker Logging Tool
100 CHAPTER 10  TOOLSis tool records vehicle detections as shown on the Verication page. Recorded vehicle detections can be used later for playback using a virtual connection.Click on the open folder icon to select a log le. e Select Tracker Log File screen allows you to specify the name of an existing log le or to create a new le (see Figure 10.6).Figure 10.6 – Select Detection Log File ScreenClick the ON/OFF toggle switch icon to the ON position to begin logging vehicle detec-tions. Once activated, the duration of the logging session is displayed on the timer display. Click the toggle switch to the OFF position to end a logging session.e vehicle detection log le is an ASCII text le and can be viewed using a standard text editor. Click on the View Log icon to view the current log le using the system’s default text editor (see Figure 10.7).Figure 10.7 – Log File

A kit with these parts can be ordered directly from Wavetronix.Size 20 contacts are used to accommodate the 20 and 22 AWG wires in the cable. (e SmartSensor 6-conductor cable’s red and black wires provide a 20 AWG wire pair. e other pairs on the SmartSensor 6-conductor cable are 22 AWG and are normally used for communication.)Follow the steps below to create a custom cable (see Figure A.2):1 Slide the strain relief, follower, grommet and back shell over the cable.2 Strip the cable jacket and shielding back about 11/2 in. (4 cm).
APPENDIX 1053 Strip each of the seven SmartSensor cable wires back about 1/4 in. (0.6 cm).4 Insert the wires into the contacts and verify the wire is visible through the contact inspection hole. 5 Crimp the wires by following the crimping tool instructions. Daniels Manufactur-ing Company provides professional grade crimping tools and detailed instructions on crimping. Wavetronix recommends the DMF AF8 M22520/1-01 or equivalent tool for crimping. 6 Manually press the contacts into the back side of the connector plug.7 Use a DMC DAK20 (or equivalent) insertion tool to fully seat the contact into the connector plug. Check the mating face of the connector to ensure that all the contacts are fully inserted. A DMC DRK20 extractions tool (or equivalent) is necessary to remove a misplaced or misaligned contact. 8 read the back shell onto the connector plug. To keep the connector from rotating during the threading process, connect the plug and coupling ring to a sensor connector receptacle.9 Press all of the connector parts together. read the strain relief onto the back shell. 10 Tighten the strain relief screws on the back.Figure A.2 – Connector Sub-assembly PartsAppendix B – Cable LengthsIt is recommended that the sensor be powered by 24 VDC to achieve reliable operation up to 500 ft.

106 APPENDIXNoteContact Wavetronix Technical Services if you have a need for a cabled connection over 500 ft. (152.4 m).Appendix C – Click 221 User Reference Guidee Click 221 is a DC 8 A surge protector (8 A is the maximum rating of a T-bus connec-tor). e DC source voltage and PE (protective earth) should be wired into the screw ter-minals on the bottom side of the device. A 12 AWG protective earth wire is recommended. e device works with up to 8 A of continuous current at a maximum of 28 VDC.NoteThis appendix covers the basics of the Click 221. For a full explanation of how to use the Click 221, see the Click Series User Guide.Outgoing DC- voltage onto the T-bus is protected from electrical surges incoming from the DC+ and DC- screw terminals. ese terminals do not have reverse-polarity protec-tion, but assumes that all downstream devices will have proper polarity protection. e surge protection meets the IEC 61000-4-S 4KV (Class 4) specication. Figure C.1 – Click 221e LED on the faceplate will be on if the device is properly powered and the surge pro-tection is operational (see Figure C.1). e LED will be o if the DC wires are wired
APPENDIX 107backwards (reverse polarity), the device is not powered or the surge protection circuitry is no longer operational. If the LED ickers on an then o when power is applied, this means that the device is conducting power, but the surge is no longer fully functional. When the surge is no longer fully functional, please contact Wavetronix Technical Services for as-sistance.Appendix D – Click 600 Installatione Click 600 cabinet interface device is a single, compact module that performs all the functions of the preassembled backplates: power conversion, surge protection, and sending detection data to the appropriate contact closure devices.Figure D.1 – Click 600e Click 600 is a shelf-mount device, meaning it’s meant to be set on a shelf in the traf-c cabinet. However, if you’d prefer to ax it to the wall of a NEMA-style trac cabinet, attach the included U-channel mounting brackets to the device and use them to mount it on the cabinet wall.Connecting AC PowerIncluded with the Click 600 is an AC power cord. Connect it from your AC power source to the IEC connector on the back of the device. e Click 600 will take that AC power and convert it to DC, then send that power to any connected sensors (which run on 10–28 VDC).WarningMake sure power to AC mains is disconnected while wiring the AC input.Next to the IEC connector is a switch that turns power on and o for the whole device.
108 APPENDIXNext to each sensor connector is a switch that turns power on and o for the associated sensor. During normal operation, be sure that all appropriate switches are turned on.CautionAn authorized electrical technician should install the preassembled backplate. Per-sons other than authorized and approved electrical technicians should NOT attempt to connect the backplate to a power supply and/or trac control cabinet, as there is a serious risk of electrical shock through unsafe handling of the power source. Extreme caution should be used when connecting the backplate to an active power supply.e Click 600 has a connector for a 5-position screw terminal, which can be used to power other Click devices in the cabinet; this will be covered in greater detail in the Using the Control Bus to Congure the Sensors section of this appendix.Providing Surge ProtectionYou don’t need to do anything to get the surge protection running; just be aware that this device provides protection for the cabinet from surges coming in on the sensor cables. (Each SmartSensor Matrix has its own onboard surge protection.)Terminating the SmartSensor 6-conductor CableEach Click 600 can interface with up to four sensors. On the back of the device are four connectors, as shown below.Figure D.2 – Click 600 Sensor ConnectorsIf you look at the side of the Click 600, you’ll see on the label that these four sensor connec-tors are labeled as 1 through 4. ese connectors are where you’ll plug in the sensor cables.
APPENDIX 109Terminating the cables in these connectors provides the sensors with DC power, lets you congure the sensor, and lets the sensor send its detection data back to the cabinet.Before you can plug in the cables, you’ll need to terminate each one into the terminal blocks included with your Click 600. e method for doing this is identical to the method used with the preassembled backplates, so for detailed instructions on how to terminate the cables, please see the Terminating SmartSensor 6-conductor Cables section in chapter 2 of this guide.NoteYou’ll note, however, that chapter 2 refers to part of the terminal block plug being blue. This is the only spot where the two terminal block sets dier; the Click 600 terminal blocks won’t have any blue portions.Once the cables have been properly terminated into the terminal blocks, plug them into the connectors on the back of the Click 600. Keep track of which connector corresponds to which sensor.Connecting the Data Ports to Contact Closure DevicesIf you look at the faceplate of the device, you’ll notice that it’s divided into two buses: Data and Control. e data bus is for taking detection data from the sensors and sending them to contact closure devices; the control bus allows users to connect to the sensors to congure them.Figure D.3 – Data Buse data bus faceplate interface consists of four RJ-11 jacks. Use the jumper cables included with your Click 600 to connect from these jacks to your contact closure devices. Informa-
110 APPENDIXtion on how to use contact closure devices can be found in chapter 3 of this guide.NoteYou don’t have to do anything special to tell the device to push data on any port; all data received on any port is automatically pushed on all other ports.e data bus portion of the faceplate also has the following features: next to each RJ-11 jack is a switch that turns power on and o to the associated sensor; under each jack is an LED that illuminates when the associated sensor has power.Using the Control Bus to Configure the Sensorse lower portion of the faceplate has the ports that make up the physical interface of the control bus. ese ports allow you to congure any sensors connected to the Click 600. You can connect to the Click 600 and thereby to the sensors using any of the following options:Figure D.4 – Control Bus RJ-11 jacks – e Click 600 has two RJ-11 jacks that allow you to connect via RS-485. USB port – Next to the RJ-11 jacks is a USB mini-B connector for connecting via USB. DB-9 connector – Under the USB port is a DB-9 connector for connecting via RS-232. T-bus port – At the bottom of the faceplate is a T-bus connector. You can use this to make the Click 600 part of a shared power and RS-485 communication bus. is isn’t usually necessary because the Click 600 performs all basic necessary functions, but it is an option.If you do intend on doing that, see the Click 100–400 Series User Guide for informa-tion about how to use a T-bus. Once you have your T-bus assembled and installed on a DIN rail somewhere in the cabinet, do the following:1 Find ve wires (or a cable) that will reach from the shelf to the T-bus; strip the ends
APPENDIX 111of each wire.2 Insert each wire into one of the screw terminals on a T-bus 5-position connector. e terminals are all labeled for your ease.3 Insert the other end of each wire into a second 5-position connector.4 Plug one connector into the T-bus port on the Click 600; plug the other into the end of your T-bus. Lastly, there are four LEDs on the faceplate. ese LEDs have the following functions: Red LED (PW) – Illuminates when device has power Blue LED (OK) – Extinguishes if device has been disabled by surges Green LED (TD) – Illuminates when data is transmitted on the control bus Yellow LED (RD) – Illuminates when data is received on the control busUse these LEDs to monitor the state of the Click 600. Appendix E – Matrix Extended Rangeere are a few things that you should be aware of when using the SmartSensor Matrix with its new extended range.Angle ResolutionAt ranges of 0–100 feet, the angular resolution is sucient to provide a ground range resolution that is close to the average width of a lane. is allows the sensor algorithms to distinguish between two vehicles traveling side by side in adjacent lanes.As the range is extended, the ground resolution gets larger. At 140 feet, the smallest beam’s footprint is about 11 feet and the outside antennas have a footprint of about 18 feet. is means that even though the center of the sensor’s view may be able to detect adjacent tar-gets, these same targets may not be detected when they are close to the edges of the sensor’s view.
112 APPENDIX200 ft140 ft100 ft26'15'18'11'13'8'Figure E.1 – Matrix Beam FootprintsIn an installation where the SmartSensor Matrix is installed in its preferred stop bar loca-tion, angular resolution will likely not be a problem. is is because as the vehicles approach the stop bar they will pass through the middle of the sensor’s view and be resolved. Also, as the cars approach the stop bar they move into a more side-re orientation to the beams and then can be resolved by their range dierences.Using the extended range to monitor two approaches puts the sensor in a position where it has to monitor lanes at its extreme edges. is is not a recommended application because the beams are the widest at the edge of the sensor’s view, resulting in unfavorable angular resolution.
APPENDIX 113200 ft140 ft100 ftFigure E.2 – Dual Approach MonitoringSignal-to-Noise Ratio and the Stop bar Eecte SmartSensor Matrix collects data beyond its advertised range. However, the signal-to-noise ratio, or the signal-to-clutter ratio, is not large enough at the far ranges to consistently detect a vehicle. is means that even though the sensor does detect some energy, the UI doesn’t show constrained trackers.is will normally not aect sensor performance for stop bar applications when the sensor detects a stopped vehicle. However, the sensor does not allow new stopped trackers to be created within a certain distance of the stop bar unless it has been detected for approxi-mately 15 seconds. is feature allows the sensor to prevent slow moving objects, such as pedestrians, bicycles and cars cutting the corner, from creating false detections. is is what is referred to as the "stop bar eect."OcclusionOcclusion becomes a bigger problem the farther the range. In the intersection, it is compli-cated by the fact that the vehicles can be stopped in a long queue, for example in a left hand turn lane, and the sensor may never see a vehicle passing in a farther lane.If the range to the sensor of an object is doubled, then the amount of ground range that can be occluded by on object is also doubled.
114 APPENDIXExampleA semi truck is is situated in a left turn lane and its far edge is 30 feet from the sensor. If the sensor is mounted 20 feet above the roadway and a 13-foot tall semi is in the lane closest to the sensor, then a vehicle that is 5 feet tall would be fully occluded within a 34 foot area. Now, in that same situation, if the lane is placed so that the far edge of the semi is at 60 feet, then the occluded ground range is doubled to 68 feet.Occluded Area30'20'13'34'Occluded Area60'20'13'68'5'5'Figure E.3 – Doubling the range of an object to the sensor doubles its occluded areaOcclusion is also made worse by the stop bar eect, especially when trying to monitor two approaches at once. When trac crosses in front of vehicles at the stop bar, they have the possibility of occluding the vehicles long enough to cause the detection to drop. If the detection drops, there will be a delay of approximately 15 seconds before the vehicles are "re-detected." e occlusion logic built into the sensor minimizes this to a certain extent, but it cannot overcome all situations.As always, if you have questions regarding the suitability of a location for SmartSensor Matrix deployment, please contact Wavetronix Technical Services or your authorized Wa-vetronix dealer for assistance.
