Introduction In the Introduction SmartSensor Matrix Package Selecting a Mounting Location The Wavetronix SmartSensor Matrix™ traffic sensor is a stop bar presence detector designed for use at signalized intersections (see Figure I-1). The SmartSensor Matrix detects vehicle demand through the use of a 24.125 GHz (K band) operating radio frequency.
Caution Do not attempt to service or repair this unit. This unit does not contain any components and/or parts serviceable in the field. Any attempt to open this unit, except as expressly written and directed by Wavetronix, will void the customer warranty. Wavetronix is not liable for any bodily harm or damage caused if service is attempted or if the back cover of the SmartSensor unit is opened. Refer all service questions to Wavetronix or an authorized distributor.
The total Wavetronix Stop Bar Detection system includes other recommended options (see Figure I-3) which include: • AC power conversion option – This option is pre-loaded onto the PCU and is normally recommended by Wavetronix instead of the DC surge protection option, because it will not burden the existing DC power modules in the cabinet and it will provide reliable power for the sensors and PCU components.
Note The Wavetronix Intersection Detection System provides a Command and Control Bridge for management of all connected SmartSensor and Click! devices. This Command and Control Bridge is completely separate from the dedicated channels used for communication of contact closure detection calls in real-time.
Figure I-4: Corner Radar Mounting pole – The sensor is usually mounted on a corner vertical mast pole or strain pole. On wide approaches the sensor can also be mounted on the back side of a mast arm using an appropriate sensor mount. In either case, the sensor should be mounted with at least a six-foot offset from the first detected lane. Figure I.5 illustrates common mounting locations: A – far side of approach, B- near side of approach, C – back side of mast arm.
Likewise, if the detection coverage is aligned so that the sensor has a view several feet beyond the stop bar (downstream from the stop bar into the intersection) it is more likely to have better performance of detecting queue dissipation. With the installation software, the presence and location of the stop bar in each lane can be configured in order to enable advanced logic to minimize the effects of occlusion of small vehicles by queued traffic.
Part I Installing SmartSensor Matrix 11
Installing the SmartSensor Matrix In this Chapter Selecting the Mounting Height Attaching the Mount Bracket to the Pole Attaching the Sensor to the Mount Bracket Aligning the Sensor to the Roadway Applying the Silicon Dielectric Compound Connecting the SmartSensor Cable Installing the SmartSensor Matrix is quick and easy. Once installed, SmartSensor Matrix configures automatically and requires little or no on-site maintenance.
55 60 or more 27 28 15 15 Table 1.1 30 30 Note It is possible to mount the sensor lower than 15 feet in some scenarios. The sensor will continue to detect vehicles at lower heights, but missed detections due to occlusion may become more prevalent or problematic depending upon your application.
Figure 1.1 – Attach the Mount Bracket to the Pole Note If you are mounting the sensor to the back side of the mast arm, you will probably need to mount the sensor down toward the road. This will allow you to use one swivel to point down towards the road and the other to pan left and right. 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 back plate with the holes in the mount bracket.
Figure 1.2 Attaching the Sensor to the Mount Bracket Note Do NOT over-tighten the fasteners. Aligning the Sensor to the Roadway In most applications, the goal is to position the corner radar so that its fan-shaped footprint provides coverage of all lanes approaching the stop bar. The sensor’s view fans out 45° to the left and 45° degrees to the right, creating a 90° corner radar. To visualize the extent of the sensor beam an installer can use a square framing tool (e.g.
Figure 1.3 – Corner radar beam position Usually the front-edge of the sensor’s beam is aligned to provide coverage beyond the stop bar. This will allow placement of detection zones in beyond the stop bar (not all vehicles stop behind the line), and it will also provide the sensor with a view of vehicles exiting queues. If the sensor pole is upstream of the stop bar as in Figure 1.2, it is recommended to pan in the direction of the stop bar. Figure 1.
Use the following steps to correctly align SmartSensor Matrix. 1. Adjust the side-to-side angle so that the front-edge of the beam 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 back plate so that the bottom-edge of the sensor is parallel with the roadway. This is necessary where the intersection approach has a significant grade.
Figure 1.6 – Sensor Connector (Left – Plug end with sockets A-H, Right – Plug and Back shell) Note If you run the cable through the pole, do not drill through the sensor mount, as the sensor and sensor mount may need to be adjusted in the future. Route the SmartSensor Matrix home run cable from the sensor location back to the main traffic cabinet. Then attach the cable to the sensor. Do not strip the service end of the cable until after it has been routed through conduit.
drain wire. The service end of the cable connects to plug-in terminals on the main cabinet back plate. Figure 1.7 – Service End Terminated At Traffic Cabinet Back Panel Figure 1.8 – Service End Labeling In Chapter 2 there is a section detailing how to properly terminate the service end of the cable (see Figure 2.6). After landing each sensor cable, and powering each sensor, you can enter location information specific to each sensor as described in Chapter 4 (see Figure 4.2).
Note To setup the network in an orderly fashion, it is recommended that labeling be used on the service end of each SmartSensor Matrix cable. Label the cables according to agency guidelines. In addition you may elect to use labels to mark the last seven digits of the serial number on each sensor, and the direction of traffic monitored (see Figure 1.8). This can help expedite software naming of sensor description, location, and approach fields.
Connecting Power, Surge, and Communications In this Chapter Mounting the Pre-wired Cabinet Unit Connecting AC Power Controlling DC Power Distribution Providing System Surge Protection Terminating the Sensor Cables Attaching the Serial Configuration Toolkit Wiring Contact Closure Communications After installation, each SmartSensor Matrix unit will need to be integrated into the traffic cabinet for power, surge, and communications.
and simplify maintenance. The wire ferrules provide a solid connection end point for screw terminal connections. Mounting the Back Plate Use the following steps to mount the back plate in the traffic cabinet: 1. Locate the space planned for mounting the back plate. Often, the PCU will be able to mount on the side panel of a NEMA style cabinet. 2. Attach the back plate with the u-channel mounting screws.
Warning Make sure power to AC mains is disconnected while wiring the AC input. The AC termination points for line (AC+, hot), neutral (AC-), and ground are found on the bottom din rail next to the 110 VAC label. Use the following steps to connect power wires from the AC terminal block or cord to the pluggable terminal blocks on the bottom din-rail (see Figure 2.2): 1. Connect a neutral wire to the bottom-side of the white block labeled “N” for neutral. The neutral wire is usually white. 2.
Figure 2.2: AC Power Conversion Each AC power conversion sub-assembly will come pre-wired as shown in Figure 2.2. The main three components of the sub-assembly include: Click! 201/202 AC to DC converter Click! 205 AC surge module Click! 206 circuit breaker and switch A Click! 201 provides 1 amp of power and is capable of powering a single sensor, while a Click! 202 provides 2 amps and can power two sensors.
one Click! 205 to both Click! 202 modules. These blocks are also used to route the DC power from both Click! 202 to the 5-position screw terminal on the left side of the T-bus. Controlling DC Power Distribution The 24V DC+ and DC- (common) connections from the AC to DC power convertors distribute power to the sensors via the Click! 222 System Surge Protection units (see Figure 2.2). The DC power wires out of the System Surge Protection units are connected to a 2.
Figure 2.2 – DC Power Distribution from System Surge Protection The four-approach PCU has the 24VDC power wired from the output of the AC to DC convertor into a 5-position screw terminal on the left side of the T-bus. This T-bus has both green and gray connectors. Green T-bus connectors conduct DC power and RS-485 communications from the left to the right side of the modules. Gray T-bus connectors conduct only DC power from the left to the right side of the modules.
Figure 2.3 – T-bus Pinout Diagram Providing System Surge Protection The Wavetronix Click! 222 system surge protection devices are designed to prevent electrical surges conducted along underground cables from damaging the cabinet equipment. Note The SmartSensor Matrix unit has built-in surge protection and there is not a need to use a pole-mount box for surge protection. However, it is strongly recommended that the sensor be connected to a surge protection device in the main traffic cabinet.
Note If the DC Surge OK LED is not lit up when the Click! 222 is powered, call Wavetronix Technical Services for assistance. Figure 2.4 – System Surge Protection The communication wires running from the pluggable termination blocks on the PCU’s bottom din-rail to the system surge protection devices are connected to provide three independent serial connections: 1. Command and Control Bridge 2. Dedicated communications for sensor A detection calls 3. Dedicated communications for sensor B detection calls.
Note When configuring the sensor, the configuration link of the install kit is rocked onto the T-BUS, to the left of the gray T-bus connector. This connects the configuration link to the Command and Control Bridge and allows for convenient access to all sensors and rack cards from one connection point. The configuration tool can automatically search for a list of all sensors or rack cards on the bus. The other two serial connections provide dedicated communications to each sensor.
Before SmartSensor Matrix is powered the wires from each sensor cable must be correctly landed into the plug-in terminals (refer to Figure 2.5 and 2.6). To land the sensor cables, use the following steps: 1. Properly strip back the cable jacket and shielding on the service end of the cable. 2. Open the insulation displacement connector using a screwdriver. Insert the wire leads into the bottom side of the plug-in terminal according to the color code show in the following table and Figure 2.4.
Figure 2.6 – Color Label on Plug-in Terminals Figure 2.
Figure 2.
Configure Contact Closure Communications Each SmartSensor Matrix unit communicates to standard traffic cabinets using Click! 112/114 detector rack cards. During real-time operations up to four channels from each sensor can be signaled to a Click! 114 (or to a pair of Click! 112 units daisy-chained together). Figure 2.7: Click! 112/114 Rack Cards The rack cards are simple to setup. The cards have been pre-configured using DIP switches to communicate at 57.6 kbps (the baud rate for SmartSensor Matrix).
On a Click! 112 channel group 1 comprises input channels 1-2, where input channel 1 will be mapped to output channel 1 and input channel 2 will be mapped to output channel 2. In order to map input channel 3 to output channel 1 and input channel 4 to output channel 2, you will need to select channel group 2. There are three ways to select channel group 2: using DIP switches, using the Mode Switch on the faceplate, or using Click! Supervisor.
Figure 2.8: Symbolic Representation of Click! 112 I/O Channel Mapping By default the DIP switches of a Click! 112/114 will be set as seen in Figure 2.9. On a two-channel card this default setting selects, Matrix output channels 1 & 2 for output. To select channels 3 & 4 move switch 4 down and switch 3 up as shown in Figure 2.10. To make the channels software configurable, set switches 1-4 down as shown in figure 2.
Contact Type Switches S2 S3 No load Channel 1&2 No load Input Mapping Switches S4 S5 3 1 Baud Rate Switches 2 1 4 5 6 7 8 2 Channel Group Channel 3&4 On 4 3 5 Bus 1 6 7 8 Off Bus 2 On a 2-channel card: selects Matrix channels 3 & 4 for ouput Figure 2.
Figure 2.8 – Surge-to-Rack Card Patch Wiring Steps 6-7 are used to connect the Command and Control Bridge used for shared access between all sensors, rack cards, and other Click! devices. 6. Run a long 6-foot patch cord from one of the Click! 222 Bridge ports to Bus 2 of the rack cards. 7. Use the short 8-inch patch cords to create a daisy-chain that shares Bus 2 between all of the rack cards. Bus 2 will be used for command and control. Once you have completed the wiring, check the main menu LEDs.
Figure 2.12 – Click! 112/114 Menu The rack cards are also fail safe. This means that when a sensor does not receive communications from a sensor within 10 seconds the rack card outputs will all active. Normally, a SmartSensor Matrix unit will send 10 contact closure messages per second. In other words, the rack card will go into fail safe mode after 100 messages have gone undetected by the rack card. All the detection channel LEDs on the faceplate will also light up when a rack card is in failsafe mode.
Figure 2.13 – Standard NEMA 8-Phase Number Scheme Phases 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 2.13. Note In the chapter on SmartSensor Manger Matrix Tools, you will find a section about Rack Card Tools which explains how the channel to phase mapping can be verified with or without the sensors installed.
Figure 2.14 – NEMA TS-2 Rack Channel to Traffic Phase Example In Figure 2.14, four channels are used from each SmartSensor Matrix unit. In this example, channel 1 from the first sensor is mapped to traffic phase 1 (left-turn phase on main street). Channels 2, 3, and 4 from the first sensor are mapped to traffic phase 6. This represents a case where detections from three throughmovement lanes are brought in separately. This type of lane-by-lane detection is beneficial in some situations.
slot 1), you can provide lane-by-lane signaling by using two Click! 112 cards for each sensor. Each pair of Click! 112 cards are daisy chained together. Figure 2.15 – NEMA TS-1 Rack Channel to Traffic Phase Example With NEMA TS1 and other legacy systems the programming is often done via a wiring panel on the side of the controller cabinet.
Part II Using SmartSensor Matrix 42
Installing SmartSensor Manager Matrix Configuration Tool In this Chapter Wavetronix Configuration Toolkit Installing SSMMX Microsoft .NET Framework The SmartSensor Manager Matrix (SSMMX) software enables users to configure and interact with the SmartSensor Matrix (SS225). This software comes preloaded on the Wavetronix Configuration Tool. This chapter gives an overview of the toolkit.
Figure 3.1 Wavetronix Configuration Toolkit Note The Wavetronix Configuration Toolkit can also be used to configure SmartSensor Advance, SmartSensor HD, and a host of Click! devices. For example, the Toolkit also comes pre-loaded with Click! Supervisor to allow software management of Click! 112/114 rack cards. To attach portable system link: 1. Rock the Click! 421 DIN rail mounted device onto the green T-bus expansion slot to the left of the gray T-bus connector. 2.
The toolkit will also come with a RJ-11 patch cord with a pigtail on one end. The pigtail is wired to the RS-485 screw terminal on the Click! 421 and can be used to patch into RJ-11 sockets on the rack cards or PCU for troubleshooting. Installing SSMMX The SSMMX software is contained on a CD that is shipped with each sensor; and it can be downloaded at http://portal.wavetronix.com. If you are unable to login, or you do not have a username, call Wavetronix Technical Services at 801-764-0277 for assistance.

Communication In this Chapter Serial Connection Internet Connection Virtual Connection Address Book Viewing Connection Information Uploading the Sensor’s Embedded Software Once the SmartSensor Matrix units are installed, use the SSMMX software to change settings, view data, and configure the sensors to the roadway. First, connect your configuration computer to the Wavetronix Stop Bar Detection System command and control bus.
Tip If you are using SSMMX on a laptop computer, you can use the panel in the lower-left of the main screen to change the size of the program on your computer. By default the smallest size is selected. If you click on the larger rectangles you can increase the size of the program by two or three times.
If you select a Full search, the search engine will go through an exhaustive process to find all SmartSensor Matrix units on the selected network bus. This process will reassign each sensor on the network bus a new communication time slot, and can take up to 30 seconds. A Quick search is much faster because it requests that each sensor respond using a previously assigned communication time slot.
Once you have selected a sensor from the device list, you can click again on that row to bring up a Sensor Info popup (see Figure 4.3). To bring up the Sensor Info popup, you can also click on the sensor icon that appears in the upper right corner of the screen (see Figure 4.2). Figure 4.3 – Sensor Info Popup The Sensor Info popup is also available on the Internet Connection and Virtual Connection screens.
1. Serial to Ethernet Converter – The SmartSensor Matrix can be connected to a local area network (LAN) by using a serial to Ethernet converter. As an option, the SmartSensor Matrix can be shipped with a Click! 301 serial to Ethernet converter that is Internet addressable, which makes it possible to connect to the sensor from anywhere the adapter’s address is accessible. 2. Serial to 802.11b Wireless – The Click! 401™ is a serial to 802.
Figure 4.4 – Internet Connection Screen Virtual Connection A virtual connection allows you to use the SSMMX software without being connected to an actual sensor. Making a virtual connection can be useful for the following reasons: • To view a saved sensor setup file. • To demonstrate functionality for different applications. • To review how the soft ware works. • To play back previously logged traffic. (This feature is not available yet) To make a virtual connection: 1. Click the Communication button. 2.
Figure 4.5 – Virtual Connection Screen Virtual Sensor File Since a virtual connection is not made to an actual sensor, a virtual sensor file (.vsf) is used to save the configuration settings much like an actual sensor’s Flash memory. If you are making a virtual connection for the first time, you will need to create a virtual sensor file by clicking on the magnifying glass icon and entering a file name.
Example If you wanted to configure channels for a future installation, you could connect using a virtual connection, create a virtual sensor file and then backup the configuration settings that you created. 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 SS200, the main menu will appear and all configuration options will become available (see Figure 4.6). Figure 4.
Click the Address Book button located at the bottom of the Communication page to add new connection settings to the Address Book (see Figure 4.7).

• Response Delay – This is used to configure how long the sensor will wait before responding to a message received. This is useful for some communications devices that are unable to quickly change transmission direction. The default value is 10 milliseconds. This value can be selected for both of the sensors ports independently. Note A green arrow is used to show the port over which SSMMX is connected to the sensor. In many cases, the SSMMX will be connected over Port 1.
Sensor Setup In this Chapter Lanes and Stop Bars Zones and Channels Verification The Sensor Setup screen allows provides automatic and manual controls to quickly and easily configure the sensor to the roadway. Configuration is a three step process that follows the tabs below the Sensor Setup title bar. Lanes and Stop Bars In Step 1 the lanes and stop bars of the corresponding intersection approach are configured.
Note When on the Lanes & Stop Bars view, you only see vehicle tracks. These tracks are not constrained to lanes, even after you have saved a lane configuration to the sensor. Vehicle detections are only viewed on the Verification View. When on the Lanes & Stop Bar view there are three display options: • Edit Area only • Edit Area with Saved Configuration Overlay • Edit Area with Automatic Configuration Overlay Figure 6.1 shows the Edit Area only.

Use the arrows to move the zone. To move just one corner of a zone, select the zone by clicking on it, and the click again on the desired node. Then drag the zone to the desired location. Zones are allowed to overlap each other. Click on the C1 through C4 LEDs to map the selected zone to the desired channels.
The Zone/Channel Map will also allow you to map or un-map zones to channels (see Figure 6.16). A zone is mapped to a channel if the corresponding LED is green. Otherwise it is not mapped. Figure 6.16 - Zone/Channel Map Popup The Edit Channel popup will also allow you to map / un-map channels. Click on the LEDs to configure the mapping. This popup also allows you to view and then edit extend and delay settings for the selected channel (see Figure 6.17).
Press the Place Auto Zones button if you would like to manually invoke this automatic feature. Please not that this will move any zone adjustments that you may have made before saving. After the configuration is complete, click the Save Config button to save the changes to the sensor. If you attempt to leave the Zones & Channels view before saving your changes you will be presented with the following prompt (see Figure 6.20). Figure 6.
Note Vehicle detections in a stopped queue are represented by a continuous light blue bar. This representation ensures that a zone will activate when queued vehicles stop before and after the zone, but not directly over it. In addition, if the first queued vehicle stops behind the stop bar and but is within 30 feet, the displayed queue will be extended to the stop bar. This ensures that a stop bar zone will activate when a vehicle stops near it in the corresponding lane.
Tools In this Chapter Backup / Restore Rack Card Tools Tracker Logging The Tools Screen allows you to perform several functions (see Figure 7.1). Figure 7.1 – Tools Screen Backup / Restore Access Backup/Restore by clicking the Backup/Restore button on the Tools screen (see Figure 7.

all the contacts are fully inserted. (A DMC DRK20 extractions tool or equivalent is necessary to remove a misplaced or misaligned contact.) 8. Thread 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. Thread the strain relief on to the back shell. 10. Tighten the strain relief screws on the back Figure B.
Appendix D – Click! 112/114 User Reference Guide The Click! 112 and 114 are 2-channel and 4-channel contact output rack cards. Each contact output is electrically isolated and are normally open. When the cards receive the appropriate serial messages from SmartSensors, they will close the contact outputs. The contact closure is used to pull-down the 24VDC reference provided by standard traffic controllers and traffic cabinet bus interface units.
When S2 is switched off it will provide a contact outputs (dry outputs) for channels 1 and 2. When S2 is switched on it will provide voltage outputs (wet outputs) for channels 1 and 2. S3 has the same functionality, but for channels 3 and 4. S2 and S3 are normally both on or both off. Note A switch is also off if it is not loaded onto the card. For example, S2 and S3 are not typically loaded because the rack card normally provides contact outputs.
Likewise, the next three baud rate switches (4-6) for S5 are used to select the baud rate for Bus 2. If these baud rate switches are all off then the Bus 2 baud rate is software configurable. Otherwise, the pattern of these switches selects the Bus 2 baud rate.
Yellow Yellow Flashing Red Flashing None Manually configure BUS1 baud rate Manually configure BUS2 baud rate Reset configuration to factory defaults Cancel and exit menu Figure D.5 Front-panel software configuration modes The Blue Flashing mode is used to select the input channels to map to the output channels. This mode will display the input channel group, but not allow it to be software configured unless the S4 DIP switch makes the channel group selection software configurable. Figure D.
Note The LED pattern of all blanks will cancel the menu and exit. Any inactivity of about 1 minute will automatically exit the menu making no selection, and return to normal operation. The Green mode is used to automatically detect the baud rate for both BUS1 and BUS2. This mode will not be present unless the S5 DIP switch makes the baud rate selection software configurable. Figure D.3 shows them submenu LED patterns that correspond to specific auto-baud actions.
○●○● ●●●● 115200 bps Error Figure D.8 – Baud Rate Encoding Note When the DIP switches control the baud rates, you the specified baud rate is displayed in the menu, but cannot be changed. The Yellow and Yellow Flashing modes are used to manually software-select the baud rate for Bus 1 and Bus 2 respectively. Figure D.3 shows them submenu LED patterns that correspond to specific auto-baud actions. While in either mode hold the mode switch until the desired submenu LED pattern is displayed (see Figure D.
Figure D.10 – Supervisor Connection and Driver Selection Figure D.11 illustrates the settings that are configurable using the Expert driver. As explained earlier, some settings are only software configurable if the hardware switches are set appropriately. For example, the baud rates for bus 1 and bus 2 are software configurable based upon the configuration of the baud rate switches on the side of the board (S5).
Figure D.12 – Rack Card Pin Out Appendix E – Click! 221 User Reference Guide The Click! 221 is a DC 8-Amp surge protection device (8 amps is the maximum rating of a T-bus connector). The DC source voltage and PE (protective earth) should be wired into the screw terminals on the bottom side of the device. A protective earth wire of 12 AWG is recommended. The device works with up to 8 amps of continuous current at a maximum of 28 VDC.
The LED on the faceplate will be on if the device is properly powered and the surge protection is operational. If the DC wires are wired backwards (reverse polarity), the device is not powered, or the surge protection circuitry is no longer operational the LED will be off. If the LED flickers on an then off when power is applied, this means that the device is conducting power but that the surge is no longer fully functional.
