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. Classified as a Frequency Modulated Continuous Wave (FMCW)

radar, the SmartSensor Matrix detects and reports vehicle presence in as many as

10 lanes simultaneously.

Figure I-1: Wavetronix SmartSensor Matrix

SmartSensor Matrix is a first-of-its-kind radar vision device that delivers the

reliability of radar and the simplicity of non-intrusive detection for stop bar

applications. The unit will work consistently in all weather and lighting conditions to

keep your intersection running safely and efficiently. In most situations the sensor

is installed on the roadside in order to prevent the need for lane closures and traffic

control. Once the unit is installed, the configuration process is quick and easy.

After installation, this unit will require little or no on-site maintenance and can be

remotely configured. This user guide outlines the step-by-step process of installing

and configuring the SmartSensor Matrix. Any questions about the information in

this guide should be directed to Wavetronix or your distributor.

SmartSensor Matrix Package

SmartSensor Matrix is the radar vehicle sensing device used in a Wavetronix Stop

Bar Detection System. The minimal stop bar detection system package contains

the following items:

 SmartSensor Matrix SS225 detector(s) with installed sensor back-plate

 Sensor Mounting Kit(s)

 Sensor Cable(s) and connectors(s)

 Pre-wired cabinet unit (PCU) with installed underground surge, termination

blocks, and DC surge option

 Detector Rack Card(s) with patch cable(s)

 SmartSensor Manager Matrix (SSMMTX) software

 SmartSensor Matrix User Guide

Standard packages are built and ready to order for 1, 2, 3 and 4 approach systems

with as many as eight sensors. Figure I-2 illustrates a 4-sensor system. Check the

packing slip for actual contents. If any of items are missing, note the serial

numbers located on the back of the sensors and contact your distributor.

Figure I-2: System Diagram of a 4-Sensor Wavetronix Stop Bar Detection System

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.

 Wavetronix Configuration Toolkit – The toolkit makes installation and

maintenance more convenient than ever. The toolkit provides both wired

and wireless configuration capability using a handheld configuration utility

and a Click! 421. The Click! 421 connects to the Command and Control

Bridge via a T-bus expansion port. The handheld configuration tool comes

preloaded with SmartSensor Manager and Click! Supervisor software, for

simple management of your system.

 Remote IP Connection option – This option is pre-loaded onto the PCU and

is recommended for remote management.

Figure I-3: Integration of Options via the Command and Control Bridge

The Wavetronix Stop Bar detection system is part of the broader Wavetronix

Intersection Detection System which includes certified systems for advance

(dilemma zone) and mid-block (system control) detection. The Wavetronix

Intersection Detection System has been designed to simply integrate the reliable

presence detection data of SmartSensor Matrix, with the superior passage detection

data of SmartSensor Advance, and high-quality count data of SmartSensor HD in

order to control signalized intersections more safely and efficiently than ever before.

Contact your authorized Wavetronix representative to learn how these packages can

be cost-effectively bundled together.

In addition the complete line of Click! products and Click! Cabinet Systems offers a

connectivity and integration solution for virtually every intersection application.

Contact Wavetronix technical services for assistance with your application specific

integration questions.

Selecting a Mounting Location

Consider the following guidelines when selecting a mounting location for each

SmartSensor Matrix unit:

 Corner radar – SmartSensor Matrix is a corner radar with a panoramic

90°degree 100-foot view. The corner radar vision device detects in traffic in

a two-dimensional matrix to provide industry leading stop bar detection

performance. The sensor’s mounting location should be selected so that all

stop bar detection zones on an approach are within 6 to 100-foot radial

distance. Figure I.4 presents a top down view of a corner radar mounted to

detect the stop bar on a four lane intersection approach. The corner radar

device uses its radar vision to automatically determine the location and

orientation of lanes and stop bars within its field-of-view. It then detects

vehicle presence on a lane-by-lane basis.

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.

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 test an alternative mounting location.

Figure I-5: Mounting locations

 Line-of-sight – Position the sensor so that it will have line-of-sight to the

entire detection area of interest. Avoid structural occlusion including trees,

signs, and other roadside structures.

 Detection coverage – Position the sensor so that it will be able to reach all

the specified stop bar detection zones. Also consider that the sensor will

track vehicles as they enter and exit desired detection zones. Accordingly,

the sensor will often work better if you position detection coverage to track

vehicles for several feet before they reach the first zone in each lane.

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.

 Closest roadside – It is recommended that you mount the sensor on the side

of the road closest to the lanes of primary interest. In many cases this will

be near side. However, if left turn detection is more critical than through

movement detection the closest road side may be the far side of the

approach. Always mount the sensor high enough to prevent traffic from

occluding approaching detections. If you mount the sensor on the back side

of a mast arm, mount the sensor near the end of the arm to reduce the

potential the mast arm or departing traffic to occlude approaching vehicles.

 Mounting height - Mounting the sensor higher will generally improve line-of-

sight and decrease occlusion of vehicles. A minimum height of 15 feet is

recommended. If the sensor is mounted on a vertical pole with a mast arm,

it is recommended that the sensor be mounted to avoid occlusion of the

roadway by the mast arm. This may require mounting the sensor below the

mast arm.

 Mounting offset – A minimum offset of 6 feet to the first lane of interest is

required.

 Redundant detection – It is possible to have multiple sensors monitoring the

same approach.

 Sensor proximity – When multiple sensors are mounted at the same

intersection, interference can be avoided by configuring each sensor to

operate on a unique RF channel. In cases, where zones are spread over

more than 100 feet, multiple sensors are needed.

 Departing lanes – There is usually no need to view traffic in departing lanes

or to configure departing lanes. However, if they are configured then the

stop bar should NOT be configured.

 Suspended electrical cables - The sensor is designed to work in the

presence of suspended power lines and other electrical cables, however

these cables should be mounted at least ten feet away from the front of the

sensor.

 Neighboring structures and parallel walls – For best performance, it is

preferred that the sensor be mounted without signs or other flat surfaces

mounted directly behind it. This will help reduce multiple reflection paths

from a single vehicle.

 Cable length – Ensure that you have sufficient homerun and sensor cabling.

Cable runs as long as 500 feet are achievable using 24 VDC operation and

the system’s native RS-485 communications. If you have an application

that requires a cable length longer than 500 feet, contact Wavetronix

technical services for assistance.

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. The

installation process includes attaching the mounting bracket to the pole; attaching

the sensor to the mounting bracket; aligning the sensor; applying a silicon dielectric

compound to the sensor connector; and connecting the SmartSensor cable to the

sensor.

Selecting a Mounting Height

After selecting a mounting location within the recommended range of offsets (see

introduction), use Table 1.1 to select a mounting height.

Warning

Caution should be used 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 traffic conditions and safety

procedures as they relate to specific locations and installations.

Table 1.1

Attaching the Mount Bracket to the Pole

Before attaching the mount bracket to the pole, first 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. Figure 1.1 illustrates the

sensor mount pointed at a 45° angle. (Figure 1.1 also depicts the sensor

attached to the mount. This is intended to help visualize the objective of

pointing the mount at a 45°. The objective is that a 45°pointing will often

provide a ballpark alignment of the sensor beam over roadway, once the

sensor is attached. The next section of this chapter explains how to attach

the sensor.)

3. Tighten the strap screws.

Note

The sensor mount may need to be adjusted later to fine-tune the alignment.

This is most easily achieved using the double-swivel mount. One swivel joint is

used to pan the sensor beam left or right. The other swivel joint is used to tilt

the sensor down towards the roadway. If you are NOT using the double swivel-

mount be sure to keep the pole straps adjustable at this point in the

installation process.

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

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. The 8-pin connector receptacle at the bottom of the unit should be

pointing towards the ground.

2. Place the lock washers onto the bolts after the bolts are in the mount

bracket holes.

3. Thread on the nuts and tighten (see Figure 1.2)

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.

Figure 1.2 Attaching the Sensor to the Mount Bracket

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. rafter square) or other solid surface with a right-angle. The tool can be

held above the sensor as a visual aid similar to the illustration in Figure 1.1. By

looking down both edges of the square instrument you can visualize the extent of

the radar’s coverage.

Note

Do NOT over-tighten the fasteners.

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 1.4 – Sensor Aligned by Rotating Towards the Stop Bar

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.

Applying Silicon Dielectric Compound

Use the following steps to correctly apply the silicon dielectric compound: Tear the

tab off of the tube of Silicon Dielectric Compound.

1. 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).

2. Be sure to wipe off any excess compound.

Figure 1.5 – Connector Receptacle (left) and Protective Earth Lug (right)

Connecting the SmartSensor Cable

The 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.

Use the following steps to connect the SmartSensor Matrix Cable:

1. Insert and turn the connector to attach it. Match up the key for a quick

connection.

2. Connect one end of a protective earth ground wire to the ground lug

terminal. A 12 AWG stranded wire is recommended for ground connections.

3. Connect the other end of a protective earth ground wire to an earth ground

connection point.

To avoid undue movement from the wind, strap the 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.

Figure 1.6 – Sensor Connector

(Left – Plug end with sockets A-H, Right – Plug and Back shell)

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. The cable should be

one continuous run without any splices.

Once the sensor cable is routed into the cabinet, prepare to label the service end of

the cable. Before you label the sensor, you may want to carefully strip back the

cable jacket and insulation of the service end of the cable (see Figure 1.7). The

wires comprise: one DC power wire pair, two RS-485 communication pairs, and a

Note

The SmartSensor Matrix cable with connector can be purchased in standard

lengths (e.g. 50, 150, or 250 feet). If you need longer cable or would like to

create custom length cables, you can also purchase bulk spools of 1000-foot

cable. When using bulk spools, you will need to purchase the plug end of the

connector and the appropriate crimping tool separately. See Appendix D for

information on crimping.

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.

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. Pre- wired cabinet units

(PCUs) are available for sensor integration. As an example, this chapter will detail

integration of a Wavetronix stop bar detection system PCU panel that

accommodates four SmartSensor Matrix units (one for each stop bar of a common

four approach intersection).

Figure 2.1 – Four approach Pre-built Cabinet Unit for SmartSensor Matrix

The standard four-approach PCU back plate is sized 11 inches wide and 11.5 inches

high. Softcopy and hardcopy plans of the cabinet unit wiring are available for

maintenance personnel. All wiring in the on the PCU is done using stranded wires

with wire ferrules for screw terminal connections. The stranded wires are flexible

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.

Connecting AC Power

Since SmartSensor Matrix operates on 10-28 VDC, the standard Wavetronix stop

bar detection system back plates provide an AC power conversion option. If you

select this option, the back plate will be loaded with the necessary AC to DC power

conversion, power surge, and circuit breaker.

If you choose to have your PCU built without the AC power conversion sub-assembly,

you will need to tap into surplus DC power capacity resident in the traffic cabinet. In

this case, Wavetronix recommends the use of the Click! 221 to protect the PCU and

SmartSensor Matrix units from DC surges. The Click! 221 is an 8-amp DC surge

module. For wiring and other information on the Click! 221 see Appendix E.

Note

If you have a 330 series (170/2070 style cabinet) with a 19” EIA rack, please

contact Wavetronix Technical Services for assistance. Wavetronix can provide

modified PCUs that attach to a 19 inch rack.

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. Connect a ground wire to the bottom-side of the green block labeled “G” for

ground. The ground wire is usually green. (Please note that the ground

connection is different than the protective earth connection. See the section

on Providing System Surge Protection for instructions on connecting to

protective earth.)

3. Connect a line wire to the bottom-side of the black block labeled “L” for line.

The line wire is usually black.

4. Connect or 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 Wavetronix stop bar detection system panel. The switch is on

if the push button is below the level of the device housing. The switch is off

if the button is raised above the surface of the housing.

6. Verify that DC power is properly regulated by checking the Click! 201/202

devices to see that the DC OK LEDs are illuminated.

Caution

An authorized electrical technician should perform installation and operation

of this unit. Persons other than authorized and approved electrical technicians

should NOT attempt to connect this unit to a power supply and/or traffic

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 this unit to an active power supply.

Warning

Make sure power to AC mains is disconnected while wiring the AC input.

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. The Click! 205

helps limit current surges on the power lines; the Click! 206 interrupts power during

overload conditions and provides a convenient way to turn power on and off for the

entire system.

A PCU will use wired blocks with one terminal at the top and two on the bottom

when one conductor needs to be routed two directions. For example, although not

shown in Figure 2.2, this type of wired block is used to connect AC power from the

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 2.0 Amp circuit breaker for each SmartSensor Matrix. The circuit

breakers provide a convenient way to switch power to each sensor independently.

When a switch is off power distribution is disabled.

To enable or disable DC power distribution, use the following steps:

1. Switch the main circuit breaker (left side of upper din-rail).

2. Switch the individual circuit breaker (left side of each sensor’s set of

terminal blocks.

Tip

With either the main or individual circuit breakers, you will enable power

distribution when the switch is on. When the switch button is level with the

device housing (pushed in) the switch is on. When the switch button is raised

above the surface of the housing (popped out) the switch is off. If you cannot

visually whether the button is pushed in or popped out, you should be able to

feel it with your hands.

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.

This means that a device that is attached to a gray T-bus connector will send RS-

485 communications to devices on its right side, but not its left side (see Figure

2.3).

For example, the gray T-bus in Figure 2.2 has its communication lines connected

with the two green T-bus devices on the right side, but not to the one on the left

side.

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.

The power and RS-485 serial connections on the T-BUS and faceplate are protected

from surges on the incoming wires of the sensor cable. The sensor cables are

connected via the terminal blocks on the PCU to the screw terminals on the bottom

side of the Click! 222. The screw terminals on the bottom side of the Click! 222

have circuitry that prevents impedance matching issues on long non-uniform cable

runs to the sensor installation sites.

The PWR and DC Surge OK LEDs indicate that the device is powered and that DC

surge protection is operational. The TD (transmit data) and RD (received data) LEDs

indicate when data is transmitted or received over the RS-485 T-bus, Bridge, C & D

ports. However, the TD and RD LEDs do not indicate data transmitted on RS485 A

or RS485 B. Furthermore, after an electrical surge there is no method to determine

if the RS-485 surge protection is still operational.

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. If you choose not to use surge protection in your main

traffic cabinet, please contact 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.

One serial connection is an RS-485 Bridge that enables a multi-drop shared

communication bus between all sensors on the panel. In a Wavetronix stop bar

detection system, the Bridge connection is designed for command and control of all

SmartSensor Matrix units, rack cards, and other connected Click! devices. This bus

is formed by wiring the C and D terminal blocks and landing the system surge

devices on a shared T-BUS.

Note

If the DC Surge OK LED is not lit up when the Click! 222 is powered, call

Wavetronix Technical Services for assistance.

The other two serial connections provide dedicated communications to each sensor.

During real-time traffic operations with multiple sensors, one sensor will send

detection calls to a detector rack card over port A, and the other will send detection

calls to another detector rack card over port B.

On a 2-sensor or 4-sensor PCU, the sensor wired into the left most terminal block

will be connected to port A & C on the leftmost Click! 222. Port A is for detection

calls and port C is connected to the Command and Control Bridge. The sensor wired

to the next terminal block from the left will be wired to port B & D on the leftmost

Click! 222. Port B is for detection calls and port D is connected to the command

and control Bridge.

Similarly, on a 4-sensor PCU the sensor wired to the third terminal block from the

left will be wired to Port A & C on the right most Click! 222. And finally, the sensor

wired to the rightmost terminal block will be wired to Port B & D on the rightmost

Click! 222.

In other words, for detection calls the ports will be used in an ABAB pattern from left

to right on a 4-sensor PCU. Likewise, for the command and control Bridge, the ports

will be used in a CDCD pattern from left to right.

All these connections are surge protected when the protective earth ground is wired

to the PE terminal block on the back plate. Normally, the back plate should be

mounted to the chassis of the cabinet to provide a ground path. In addition it is

strongly recommended to provide a low impedance protective earth connection.

To provide a low impedance protective earth connection:

1. Connect a protective earth ground wire to the bottom-side of the PE block. A

10 AWG stranded wire is recommended for protective earth ground

connections. A 10 AWG wire is the largest that will fit in the terminal block.

2. Connect the protective earth ground wire to a protective earth screw

terminal within the main traffic cabinet.

Terminating the Sensor Cables

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.

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. Make sure the wires are

bottomed in the terminal.

3. Close the insulation displacement connector using a screwdriver. The plug-in

terminals will automatically displace the insulation and complete the

electrical connection. (There is no need to manually strip the insulation on

the end of each wire.)

The insulation displacement connector plugs are keyed from left to right. The blue

socket can be used to visually see which plug goes into which terminal block. On

the leftmost terminal block, the PWR connection is blue (not gray like the others).

On the next terminal block, the GND connection is blue. The blue connection

continues to move one connection to the right as you move from left to right.

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). DIP

switches have also been used to select a group of input channels coming from

SmartSensor Matrix to signal on the Click! 112/114 output channels. The factory

default setting for the Input Mapping switches selects channel group 1.

On a Click! 114 channel group 1 comprises input channels 1-4. When this channel

group is selected; input channel 1 will be mapped to output channel 1, input

channel 2 will be mapped to output channel 2, input channel 3 will be mapped to

output channel 3, and input channel 4 will be mapped to output channel 4.

Note

If you have space in your detector rack, Wavetronix typically recommends

using a 4-channel card. This simplifies the installation process and allows you

to us all four channels from SmartSensor Matrix. If you have a detector rack

that only accepts 2-channel cards (e.g. 170/2070 controller types), then of

course this is your best option. Daisy chain pairs of 2-channel rack cards

together in order to receive all four channels from each sensor. If you do not

have a detector rack in your cabinet, contact Wavetronix technical services for

assistance.

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.

The DIP switches override the Mode Switch and Click! Supervisor, so if you are

planning on using either the Mode Switch or Click! Supervisor then you will need to

first check that the DIP switches are set to allow for software configuration.

One benefit of using DIP switches to select the channel group is that if you ever

have a field service call and need to replace a Click! 112, all you need to do is

match the pattern of the DIP switches on the card you are replacing. This paradigm

will even work in situations where the old rack card will not even power up.

On the other hand, a benefit of using the software configuration is that you can

remotely manage the configuration of the cards (assuming you have interconnect to

the traffic cabinet and a Click! 301 or equivalent device on the Command and

Control Bridge). In this paradigm, it becomes the responsibility of the traffic

manager in the operations center to keep a record of how each card was

configured.

Tip

The status of SmartSensor Matrix output channels are sent using a contact

closure serial communications message (see Figure 2.8). Bits within the

message are dedicated to channels 1, 2, 3, and 4. If the designated bits are

set to 1 the associated channel is on (contact closed on rack card), and if they

are set to 0 the associated channel is off (contact open on rack card). When

the serial message sent by a SmartSensor Matrix reaches a rack card the

sensor output channels are now considered rack card input channels. It is then

the job of the rack card to relay the status of the input channels (sensor output

channels) to the selected rack card output channels.

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 2.11

At a maximum each sensor uses one 4-channel card or two 2-channel cards for

normal operations. This means that a standard 4-approach stop bar detection

system can be accommodated by a 16-channel detector rack. Use the following

steps to setup the contact closure rack cards for each sensor.

1. Plug all the cards into the detector rack. This will provide power.

Steps 2-5 are used to connect the isolated detection call links used for real-time

traffic control.

2. Run a long 6-foot patch cord from the Click! 222 RS-485 A port to a Bus 1

port on the appropriate rack card.

3. Run a long 6-foot patch cord from the Click! 222 RS-485 B port to a Bus 1

port on another rack card.

4. If using 2-channel rack cards, use a short 8-inch patch cord to share BUS 1

between cards dedicated to the same sensor. Also, configure one card to

use Matrix channels 1 & 2 and configure the other card to use Matrix

channels 3 & 4.

5. If you have more than 2 sensors in your system, reuse steps 2-4 to connect

Bus 1 for all remaining rack cards.

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. The red PWR LED

should be on indicating that the card is powered and in normal operating mode. In

normal operating mode you will observe the following:

• The green TD LED will activate whenever the card transmits serial

communications.

• The yellow RD LED will activate whenever the card receives serial

communications.

• The red detection channel LEDS (on top) will light up when a call is placed

on the corresponding contact closure output channel.

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.

For additional information about Click! 112/114 rack cards consult Appendix D.

Once the Click! 112/114 rack cards are installed, you will need to make sure that

each detector rack channel is properly mapped to correct traffic phase in the traffic

controller. The general NEMA standard for 8-phase numbering is presented in

Figure 2.13. In practice, many intersections will not have 8 phases and in some

cases they may not even follow the NEMA convention. Check the plans in the traffic

signal cabinet to verify how the phases are numbered at each intersection.

Note

Detection call messages are sent by SmartSensor Matrix 10 times per second.

The latency from transmission by the sensor to actuation on the backplane of

the rack card is less than 3.5 milliseconds.

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.

Since each Matrix unit often detects both the left-turn phase and the through-

movement 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.

NEMA TS2, 2070, and other advanced traffic cabinet systems usually allow

software programming of the detector card channel outputs to traffic phases via a

channel-to-phase mapping grid in the controller menu. Figure 2.14 illustrates how

the detector channels 1 to 16 of a NEMA TS-2 rack can be assigned to the standard

8-phases using four Click! 114 cards. The rack card slots are numbered across the

top and the channel positions are represented by the gray labels C1 – C16.

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 through-

movement lanes are brought in separately. This type of lane-by-lane detection is

beneficial in some situations. Wavetronix typically recommends the use of 4-

channel cards in racks that will accommodate them, because it offers greater

flexibility of signaling contact closures.

Figure 2.15 illustrates how the detector channels 1 to 8 of a NEMA TS-1 rack can be

assigned to the standard 8-phases using four Click! 112 cards. The rack card slots

are numbered across the top and the channel positions are represented by the gray

labels C1 – C8. This example has the economy of only using four rack slots, but it

does not provide lane-by-lane signaling of the through-movement for cases where

there are multiple through lanes. If you are using a rack with a two-channel

dominant scheme (Four channel cards are not allowed and channels 1 and 2 are in

Note

The channel positions in Figure 2.14 are representative of their arrangement

when two-channel cards are used, even though four-channel cards are

depicted in this example. In reality, all the channels of a four-channel rack

card are signaled through the backplane contacts connected into the in the

even numbered rack slots. NEMA TS-2 channel order is based upon a four-

channel dominant scheme, instead of two-channel dominant scheme. A four

channel dominant scheme will allow two-channel or four-channel cards to be

inserted, but the numbering is based upon a four-channel card. This is why

channels 1 and 2 are in slot 2, instead of slot 1.

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. With wired systems you will need

to verify that the wiring on the detector programming panel provides the proper

mapping from the rack channel outputs to the controller input wires dedicated for

ф1-ф8 detector calls.

Using SmartSensor Matrix

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.

Also if you are not using the toolkit, or if you would also like to install SmartSensor

Manager Matrix on other devices, this chapter explains how you can get SSMMX up

and running.

Wavetronix Configuration Toolkit

The Wavetronix configuration toolkit is available for reliable and convenient

management of Wavetronix stop bar detection systems. The toolkit includes:

• A portable system link

• A handheld configuration device

• SmartSensor Manager Matrix and other Wavetronix configuration software

The portable system link will convert the wired or wireless serial data to RS-485 and

then send it to all devices on shared multi-drop communication bus on the PCU in

order to allow command and control of all SmartSensor Matrix units from a single

access point.

The portable system link (Click! 421) provides both a wired and wireless serial

connection to the handheld configuration device. The wired connection is made

using a USB-to-serial convertor and a USB adapter cable.

The wireless connection is made via preset Bluetooth serial link. A whip antenna

can be attached to the Click! 421 to increase the roaming distance and reliability of

the serial link.

The handheld device is lightweight for extended use outdoors and its screen has

provides for excellent viewing in bright outdoor settings.

Figure 3.1 Wavetronix Configuration Toolkit

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. Make a serial connection between the DIN rail mounted device and the

handheld. In the case of a wired connection, you will need to physically

connect the serial cable from the handheld device. You can add a USB

extension cable to increase the length of you run is necessary.

If you wish to establish a wired connection with a laptop computer instead of the

handheld device, use the laptop’s native RS-232 serial port to connect to the Click!

421. Or a USB-to-serial convertor if the laptop does not have an RS-232 serial port.

You may also wish to establish a Bluetooth connection from your laptop to the Click!

421. To do so, consult your laptop’s software guidelines on how to discover

Bluetooth devices and configure a Bluetooth serial connection.

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.

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.

SSMMX can be run on a Windows® PC or on the handheld of the configuration

toolkit (It is not supported on other Windows® CE devices). Everything needed to

install SSMMX to a PC is contained in the SSMMX Setup.exe file.

Follow these steps to install SSM MX on a PC:

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. Next, launch SSMMX by either clicking on the

icon that was placed on your desktop or clicking the icon found in the Start menu.

The SSMMX main screen shown in Figure 4.1 will appear.

Figure 4.1 – SSMMX Main Screen (New Screenshot needed)

To interact with and configure Matrix sensors with SSMMX, connect to the sensor

through one of the following three types of connections:

 a serial connection;

 an Internet connection, made using an IP address and a serial to Ethernet

converter;

 or a virtual connection, which can be made for convenience in learning and

demonstrating SSMMX functionality.

Serial Connection

1. Click on Communication to access the Communication window (see Figure

4.2).

2. Select the Serial tab.

3. Set Port and Timeout to the desired settings.

4. Select the type of search you would like to perform using the radio buttons

(Full or Quick).

5. Click the Search button. Please wait up to 30 seconds while the sensors on

your network bus are discovered and listed. (You can click Cancel, if the

sensor of interest has already been listed.)

6. Click on the desired row from the list to select a sensor. The list presents

the Sensor ID, Location, and Approach fields of each sensor discovered.

7. Click the Connect button. When a connection is established you will be

directed back to the home page.

Tip

Click the magnifying glass icon on the right side of the communication link of

the main SSMMX page to help expedite completion of a connection using the

most-recently-used parameters. For example, if your most recent connection

was an Internet connection, click on the magnifying glass to bring up the

Internet tab with the last IP Address, port, and timeout values specified. When

the page appears, you will notice that SSMMX is searching at the selected

destination using the last type of search (Quick or Full) that you selected. The

magnifying glass will only appear when there is no connection currently

established.

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. However, a quick search should not

be used the first time you connect to a network, or if you have added a new sensor

to an existing network, because by default sensors may have conflicting time slots.

The first time you connect to a sensor network bus, the default Sensor ID of each

discovered sensor will be unique (based upon the last seven digits of the serial

number). However, the default names in the Location and Approach text fields will

all be the same.

To setup network names (e.g. Description, Location, and Approach) in an orderly

fashion, it is recommended that the circuit breaker switches be used to selectively

power sensor. First, power only one sensor and enter its naming information. Then

repeat this process to power additional sensors, one at a time.

Figure 4.2 – Serial Connection Screen (New Screenshot needed)

Tip

It is recommended that you use labeling on the service end of each

SmartSensor Matrix cable (see Figure 1.8). If you have not already labeled the

service end of the sensor cable, you may be able to do so now. If not, you may

need to rely upon traffic patterns to sort out the sensors.

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. This screen lists the following sensor settings and version

information:

• Sensor ID – Unique Address (by default based upon the last seven digits of

the serial number).

• Description – User-definable 32 character text field use to describe the

sensor. Can be used to indicate items such as the application (e.g. stop bar

detection) or GPS coordinates.

• Location – User-definable 32 character text field typically describing the

intersection where the sensor is located (e.g. “Main & Center – Anytown

USA”).

• Approach – User-definable 32 character text field that typically indicates

which approach of the intersection the sensor monitors (e.g. “EB Main

Traffic”).

• Sensor Version – Overall sensor product version which represents a released

combination of the DSP, Algorithm, FPGA, and FPAA subcomponent

versions.

• DSP Rev – DSP code version as a date (YYYY-MM-DD).

• Algorithms Rev – Algorithm code version as a date (YYYY-MM-DD)..

• FPGA Version – FPGA version as a date (YYYY-MM-DD).

• FPAA Version – FPAA version as a date (YYYY-MM-DD).

The Sensor Info popup also has a Signal Rack Cards toggle switch. When the switch

is on, any rack cards connected to this sensor will identify themselves by flashing a

blink sequence on the main menu LEDs of the rack card (see Figure 2.10).

Internet Connection

The SmartSensor Matrix can be connected to the Internet allowing access to the

sensor from anywhere with Internet access. Below is a list of three ways to connect

the SmartSensor to the Internet:

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 802.11b

converter that provides serial devices with an IP address on a wireless

802.11b network.

3. Internet Service Providers – Cellular providers of wireless internet services

maintain networks in most metropolitan areas in the United States and

coverage continues to expand. The SmartSensor Matrix can be equipped

with optional external modems—for example, CDMA, GMS or GPRS— and

assigned an Internet address on these networks. (Please test that

SmartSensor Matrix will work with a particular manufacturer’s modem, or

contact Wavetronix technical services for assistance and guidance.)

Use the steps below to connect to the SmartSensor Matrix using an Internet

connection:

1. Click on Communication.

2. Click the Internet tab and the Internet setting options will appear (see Figure

4.4).

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. Select the Virtual tab (see Figure 4.5).

3. Select or create a virtual sensor file (.vsf) by clicking the magnifying glass

icon.

4. Select the type of search you would like to perform using the radio buttons

(Full or Quick).

5. Click the Search button. Please wait up to 30 seconds while the sensors on

your network bus are discovered and listed. (You can click Cancel, if the

sensor of interest has already been listed.)

6. Click on the desired row from the list to select a sensor. The list presents

the Sensor ID, Location, and Approach fields of each sensor discovered.

Click the Connect button. When a connection is established you will be directed

back to the home page.

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.

Backing up a virtual sensor file will change the file to a sensor setup file (.ssc) that

can be restored to an actual sensor. To convert a sensor setup file to a virtual sensor

file, make a virtual connection and then use the Restore Sensor Setup tool in the

Tools menu. To convert a virtual sensor file to a sensor setup file, use the Back-up

Sensor Setup tool.

Note

When 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.

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 4.6 – Main Menu (Connected)

If you have problems connecting:

1. Make sure that all power and communication wiring is correct;

2. Check the Port settings (Port ID).

Connection failure can occur for various reasons; if a failure occurs repeatedly, call

Wavetronix Technical Support at 801-764-0277 for assistance.

Address Book

PLEASE NOTE – The Address Book is still under design. The documentation in this

section will need to be updated once the software is completed. For now this

explanation is just a placeholder.

The Address Book allows you to save device connection settings for future use.

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.

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).

Figure 4.7 – Address Book and Address Book Filter (New Figure Needed)

Viewing Connection Info

Once connected, you can view additional information about the connection you

have established 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 4.8).

These arrows are only visible when there is an established connection.

Figure 4.8 – Connection Info Screen

Below is a list of the information available on the Connection Info screen:

• Status. – Shows that you are connected.

• Device – Shows the Subnet and sensor ID.

• Type – Shows the type of connection and baud rate.

• 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

The error log contains all errors stored in the sensor’s memory buffer. 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 file and contact

Wavetronix Technical Services.

Click the View Error Log link to view the communications error log (see Figure 4.11).

The error log can also be accessed by clicking on the Error Log icon at the bottom of

the Communication screen.

Figure 4.11 – Error Log

Uploading the Sensor’s Embedded Software

After clicking the Connect button, the soft ware will check to see if your soft ware

version matches the version of the sensor’s embedded soft ware. If a discrepancy is

detected, the Version Control screen may appear asking you to install firmware

upgrades (see Figure 4.12). If you think you have reached this screen in error,

clicking the Recheck button will have the soft ware retry and ensure that there has

not been a communication issue. Clicking the Details button will display the current

sensor and soft ware information. Click the Install Upgrade button to upgrade the

software.

Figure 4.12 – Sensor’s Embedded Software Upgrade (left) and Details Table (right)

Click the Details button to view the firmware versions of both the SSMMX software

and the sensor.

Once the Version Control screen appears, you can do one of the following:

1. Upgrade the sensor’s embedded software by clicking the INSTALL UPGRADE

button.

2. Click the close button and continue the configuration process.

3. Find the version of SSMMX software that is compatible with the sensor’s

embedded software.

If the row marked Digital is highlighted in red, the firmware upgrade may need to be

installed. Compare the Sensor number with the SSMCE number in the Digital row of

the details table. If the SSMMX firmware version date is more recent than the

sensor firmware version date, the firmware upgrade will need to be installed; if the

sensor’s firmware date is more recent than the SSMMX firmware version date, a

warning will appear notifying you that the sensor firmware could be downgraded

(see Figure 4.13).

Warning

Clicking the

button and continuing configuration without upgrading may

cause problems with functionality.

Figure 4.13 – Sensor Firmware Downgrade

If the downgrade message appears, it simply means that the sensor firmware is

newer than the version of SSMMX that was used to connect to the sensor. The

newest version of SSMMX can be updated by downloading the software from the

Wavetronix Portal.

Click the INSTALL UPGRADE button to install the firmware embedded in SSMMX

onto the SmartSensor Matrix. The Recheck button will query the sensor to see if the

firmware bundled in SSMMX is different than the version running on the sensor.

Sensor Settings

In this Chapter

 Sensor Settings

Click the Sensor Settings link on the main menu to change and save settings on the

sensor.

Figure 5.1 – Serial Settings Window (New Screenshot Needed)

The Sensor Settings window contacts the following fields (see Figure 5.1):

• Serial Number – Contains the sensor serial number and cannot be edited.

• Sensor ID – ID used to uniquely identify all sensors on a multi-drop bus. This

ID is based upon the last seven digits of the Serial Number and cannot be

edited.

• Description – Allows you to enter a description for each sensor. Limited to

32 characters.

• Location – Allows you to enter the intersection location of the sensor.

Limited to 32 characters.

• Approach – Allows you to enter the direction of traffic the sensor is

detecting (e.g. NB, SB, WE, WB). Limited to 32 characters.

• RF Channel – Displays which radio frequency channel the sensor is using.

There are eight RF channels available. Using multiple sensors in close

proximity will require each sensor to be set to a different RF channel (see

the introduction for more information about mounting sensors in close

proximity).

• Sensor Height – The height of the sensor in feet. This value impacts the

performance of the sensor.

• 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.

• Data Push – Data can be pushed over port 1, port 2, or both. To prevent

data push, select “None”. In many cases, data push will only occur over Port

2 which is typically designated for detection calls (based upon the pre-wired

connections of a PCU).

• 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 not longer used.

Instead a predetermined sequence of traffic will appear. The replay source

is only available if the sensor is equipped with this special hardware.

Note

If for some reason SSMMX connects over the Port that SmartSensor Matrix is

pushing data, the software will continue to poll the sensor for detection call

messages. This will help keep the intersection operating as normal during the

configuration process.

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. Port 1 is

usually designated for command and control and is connected to the blue RS-

485 wire pair. However, during troubleshooting or other special cases SSMMX

may 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.

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. Lanes, stop bars, and vehicle tracks are shown within the sensor’s 100-

foot 90° degree view (see Figure 6.1). This view has the appearance of a baseball

infield with the sensor icon shown at the position where home base would be.

Figure 6.1 – Lanes & Stop Bars View (Edit Area)

Before any lanes are discovered you will see vehicle tracks in the auto-configuration

view. Vehicle tracks can be represented with or without a track history. To toggle

the track history on or off press the little detection display button below the middle

of the sensor view. When it the track history is on the button will appear like as a

circle . When the track history is off the button will appear as a vertical series of

dots .

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. The Edit Area shows changes that have been

made within SSMMX, but that have not yet been saved on the sensor. Figure 6.2

shows the Lanes and Stop Bars view with the Saved Configuration Overlay (left) and

the Automatic Configuration Overlay (right). To show or hide these overlays toggle

the Saved Cfg and/or Auto Cfg buttons. These buttons are found below the sensor

view and above the menu bar.

SmartSensor Matrix is constantly running the auto-configuration process in order to

find undiscovered lanes and stop bars.

Figure 6.1 – Lanes & Stop Bars View with Overlays

The menu bar at the bottom of the screen will allow you to perform a variety of

operations during Sensor Setup. Press the yellow up-arrows icon at the right side of

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.

the menu bar to open a pop-up view of the Lanes & Stop Bars menu (see Figure

6.2).

Figure 6.2 – Sensor Setup Menu Popup

Use the blue back-arrow to return to the main menu. Click the Save Config button

to save the sensor configuration at any time. To undo the last change in the Edit

Area, click the Undo Last Edit button. To clear all your pending changes, click the

Clear Edit Area. Click the Pause Traffic / Play Traffic button to suspend or resume

movement of vehicle tracks on the screen.

In general, the following order is recommended for completion of Step 1 – Lanes

and Stop Bars.

1. Move Sensor to correct location.

2. Restart Automatic Lane Configuration. Allow the automatic configuration

process to run for several cycles around the intersection (approximately 5 to

10 minutes).

3. Capture Lanes & Stop Bars to Edit Area

4. If necessary, make manual adjustments to the Lane & Stop Bar

Configuration using the Edit Area

5. Save the desired changes to the sensor.

Move Sensor

The sensor is typically used to monitor traffic on one approach of the intersection.

Often the sensor is mounted on the near-side of the approach near the intersection.

In this case the sensor monitors the traffic approaching the stop bar as it travels

towards the sensor. If your sensor is not mounted from this vantage point, click the

Move Sensor Icon until the sensor has moved to the correct corner of the screen.

The sensor will move in the following sequence:

• Bottom left-hand corner - near side of approach monitoring traffic traveling

towards the sensor’s location.

• Top left-hand corner - near side of approach monitoring traffic traveling

away from the sensor’s location.

• Top right-hand corner - far side of approach monitoring traffic traveling

away from the sensor’s location.

• Bottom right-hand corner - far side of approach monitoring traffic traveling.

This sensor placement allows direct line-of-sight to the first left turn lane.

Restart Automatic Lane Configuration

When you enter the Sensor Setup screen for the first time, restart the auto-

configuration process to erase auto-configuration information that may have been

gathered before the sensor’s alignment was finalized.

To restart the automatic lane configuration process:

1. Click the Restart or Reboot button

2. Click OK on the Restart of Reboot popup window (see Figure 6.3).

Figure 6.3 – Restart or Reboot Popup

Capture Lanes and Stop Bars to Edit Area

When auto-configured lanes appear they can be captured by clicking on them.

Once a lane is captured it becomes part of the Edit Area. Captured lanes are not

saved to the sensor until after clicking on the Save Config button.

To capture a single lane:

1. Click on the lane once to select it.

2. Click on the lane a second time to bring up the Capture pop-up window (see

Figure

3. Click on the Capture Lane button to capture the selected lane.

Edit Node popup (see Figure 6.8).

3. Click on the arrows to move the node in the desired direction. The

numbered pair (x,y) between the arrows indicates the distance within the

sensor’s view. The x-value indicates the distance from the right edge of the

sensor’s view in (feet). The y-value indicates the distance from the left edge

of the sensor’s view (In feet).

Adjacent lane nodes can be placed to follow the curve of a turn movement.

However there is a limitation to the amount of curvature that is acceptable (see

Figure 6.9). The departure from a straight path cannot exceed 45 degrees. While

you will be able to allow move the node anywhere on the screen you will get a

notification that the “lane configuration is invalid” if the allowable limits are

exceeded.

Save Desired Changes to the Sensor

After the configuration is complete, click the Save Config button to save the

changes to the sensor. If you attempt to leave the Lanes & Stop Bar view before

saving your changes you will be presented with the following prompt (see Figure

6.12).

Figure 6.12 – Save Changes Dialog

Zones and Channels

After the Lanes and Stop Bar configuration is saved, click on the Step 2 tab to bring

up the Zones & Channels view. This view allows you to place zones and configure

detection channels (see Figure 6.3). Each SmartSensor Matrix unit supports up to

eight zones and four channels. If unused, the eight zones are placed outside the

sensor view and labeled Z1 through Z8.

Detection zones are automatically placed in each lane near the stop bar. By

default, the zones are 30 feet in length. Each automatically placed zone is then

mapped to a detection channel.

To make changes to the zones and channels use the menu bar (see Figure 6.14).

Figure 6.13 – Setup Zones & Channels View

Figure 6.14 – Setup Zones & Channels Menu Bar

The Edit Zone button will allow you to move a zone, and also specify the channels to

which it is mapped. 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.

If the LED is green the zone will be mapped to that channel. If it is gray then it will

not be mapped.

Figure 6.15 – Edit Zone Button

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). To edit the

extend and delay, click in the white box with the E and D, and the corresponding edit

boxes will appear (see Figure 6.18).

Figure 6.17 – Edit Channel Popup

Figure 6.18 – Edit Extend Delay

The extend and delay settings can also be specified using the Output Settings popup

(Figure 6.19). This popup also allows you to specify the minimum pulse width. The

minimum pulse width is the minimum duration a presence detection will be

signaled via the contact closure rack cards. All these output settings are specified

in seconds.

Figure 6.19 – Output Settings Popup

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 6.20 – Save Changes Dialog

Verification

After the configuration is complete, you will want to verify vehicle detections. To do

so click on the Step 3 tab. This will bring up the Verification View (see Figure 6.21).

Figure 6.21 – Verification View

In the Verification View, vehicle detections will appear as light blue objects. The

extent of these detections will vary based upon the length of the detected vehicle

and the length of queued traffic.

When detections are within a zone, they will cause the LEDs for the channels

mapped to that zone to activate. Active channels will appear red, and inactive

channels will appear gray (blank).

To see detections active the zones mapped to a particular channel, select that

channel by clicking on its LED. Active zones for the selected channel will appear

red, and inactive channels for the selected zone will appear black (blank).

As on the Edit Lanes & Stop Bar screen, you can use the menu bar to: save a

configuration, undo your last edit, edit thresholds, and pause/play traffic (see Figure

6.22).

Figure 6.22 – Verification View Menu Bar

Note

Only the zones for the selected channel will appear. If zones are not mapped

to any channel, they will not be seen in the Verification View.

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 7.2)

Figure 7.2 – Backup / Restore

The backup function allows you to backup the sensor settings you have changed. To

create a backup, click on the magnifying glass icon in the Back-up File section.

Choose a destination, type in a filename, and hit OK, then click the Back-up Sensor

Setup button.

The 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 file you wish to restore, hit OK, and then click the Restore Sensor Setup

button.

Warning

Restoring sensor settings will cause you to lose the settings previously on the

sensor, unless they are backed up.

Note

The backup will appear as an .ssc file. While this file can be opened as a text

file by using a program such as Notepad, do not edit the file, as it will change

the settings you backed up.

Rack Cards Tools

Access rack card tools by clicking the Rack Card Tools button on the Tools screen

(see Figure 7.3)

Figure 7.3 – Rack Card Tools

Serial data messages sent by the Rack Card Tool normally reach the rack cards via

T-bus and the patch cord connecting the Command and Control Bridge directly to

contact closure card shared multi-drop bus. The Rack Card Tool does not cause the

sensors to send contact closures to the rack cards.

Note

To reduce the amount of time spent onsite when installing a Wavetronix Stop

Bar Detection System, you can use the Rack Card Tool to setup the racks

cards, while cable is being pulled through conduit or the sensors are being

installed. This tool will allow you to verify that you have the correct channel

mapping into the traffic controller, even without the sensors installed. This tool

can also be used for troubleshooting.

To search for Click! 112/114 rack cards on the communication bus to which

SmartSensor Manager is connected:

1. Select the correct communications port using the Port drop down control.

2. Select the correct communications baud rate using the Speed drop down

control.

3. Click on the Search button.

4. Once a list of devices appears, click on the desired row. If you would like to

communicate to all the devices, select the first row, with the title “All Rack

Cards” in the device column. This selection will send broadcast messages to

all the connected rack cards. If you would like to communicate to an single

device, select the corresponding row. You can identify a device by its ID,

Device, Description, or Location fields.

When you are communicating with an individual device, the Status and Firmware

Version fields will be valid. The Status field indicates whether the rack card is

operating normally (OK) or whether it is in failsafe mode. If the device is in failsafe

mode, the text message may help you understand why the device is in failsafe. For

example if the text reads “Failsafe Initializing”, this indicates that the rack card has

never seen any detection call messages since it was rebooted. Or if the message

reads “Failsafe Timeout (No Data)”, this indicates that the rack card was previously

receiving detection calls, but has received any in the last 10 seconds or more.

The Firmware Version field lists the version of the rack card firmware. In the

example in Figure 7.3, the firmware is for a 114 card and was released on

11/06/2008. If you are communicating will all devices, the status and firmware

version fields are not applicable (N/A). When you would like to refresh the status of

these fields, click the associated Refresh button.

To help single-out devices you can use the Signal Cards toggle switch. When the

switch is ON, all selected devices will flash their main menu LEDs (see Figure 2.10).

If you have selected All Rack Cards, every card connected on the bus will flash the

main menu LEDs. If you have selected a single device, only the LEDs on this device

will flash.

The Channel Outputs toggle switch and 1-4 checkboxes are used to help assist in

testing of the rack card outputs. Boxes 3 and 4 will not appear if you are connected

to a two-channel rack card.

Note

When used with SmartSensor Matrix the rack cards should be configured to

communicate at 57,600 bps. If you are having communication issues, you

may want to verify that the rack cards are configured to communicate at

57,600 bps. See Appendix D to learn how to configure the rack cards.

If the Channel Outputs switch is ON, all the selected outputs on the Click! 112/114

rack card will be determined by the checkboxes (unless a sensor is actively pushing

data to the rack card over the detection call bus).

If there are not competing messages from another communication bus, an output

will be active when associated a box is checked. An active output will cause the

corresponding contact outputs on the card’s backplane to close and the detection

channel LED on the faceplate to activate (see Figure 2.10). If a box is not checked,

the output will be inactive. An inactive output will cause the corresponding contact

outputs on the card’s backplane to open and the detection channel LED on the

faceplate to deactivate.

When on the Channel Outputs toggle switch and 1-4 checkboxes can be very helpful

in verifying the I/O channel mapping from the rack card outputs to the traffic

controller inputs. By sequentially checking boxes 1-4 you should be able to quickly

verify the mapping of each channel, even in the absence of traffic.

Tracker Logging

Access the Tracker Logging tool by clicking on the Tracker Logging button on the

Tools screen (see Figure 7.4). This tool will allow you to log vehicle detections as

Note

If the Channel Outputs toggle switch is OFF, no channel output messages will

be sent to the Click! 112/114. However, this does not mean that the channel

outputs will be inactive. In fact, normally the cards will go into failsafe mode.

In failsafe mode, all detection channel outputs and their corresponding LEDs

will be active.

Warning

It is recommended that you disable pushing by sensors, or disconnect the

Appendix B – Matrix Cable Connector Assembly Information

The connector end of the SmartSensor Matrix cable mates to the eight socket

connector on the sensor as shown in Figure B.1. Socket A is near the connector’s

key. Figure B.2 details the pinout of the cable connector and the corresponding wire

in the cable. The SmartSensor Matrix cable has 7 wires. Internal to the sensor

another pair of wires connect to the protective earth lug.

Figure B.2 – Pinout for Power and Communication Signals

To create custom cables proper connector crimping tools are necessary. The

SmartSensor Matrix cable connector uses a MILC-C-26482 Series 1 connector,

crimping contacts, and a watertight back shell. A kit with these parts can be

ordered directly from Wavetronix.

Size 20 contacts are used to accommodate the 20 and 22 gauge wires in the

cable. (The SmartSensor cable’s red and black wires provide a 20 AWG wire pair.

The other pairs on the SmartSensor cable are 22 AWG and are normally used for

communication.)

To create a custom cable (see Figure B.3):

1. Slide the strain relief, follower, grommet, and back shell over the cable.

2. Strip the cable jacket and shielding back about 1.5 inches.

3. Strip each of the 7 SmartSensor cable wires back about 0.25 inches.

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

Manufacturing 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 backside of the connector plug using

the pinout information in Figure B.2.

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. 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

Appendix C – SmartSensor Matrix Cable Lengths

It is recommended that the sensor be powered off of 24 volts to achieve reliable

operation up to 500 feet away. Figure C.1 lists maximum cable lengths for 12 and

24 volts.

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. This

type of digital I/O is standard in NEMA TS1, NEMA TS2, 170, 2070, and ATC traffic

cabinet systems.

When used with SmartSensor Matrix the rack cards usually receive broadcast

detection call messages. However, the rack card protocol also supports individual

addressing. Individual addressing is used by the rack card tools in SSMMX.

The rack cards are software and hardware configurable. Hardware configuration is

performed using switches on the side of the card (see Figure D.1).

Figure D.1 – Hardware Configuration Switches

Figure D.2 illustrates the 4 possible DIP switch modules on the side of the card. To

turn a switch on, push it up. To turn a switch off, push it down. In this example, only

switches 1 and 4 of S5 are on.

Figure D.2 – DIP Switches on the side of the card

Note

On power up, the rack cards will go into failsafe mode if they are not receiving

detection call messages from SmartSensor Matrix. So even though the

contact outputs are normally open, they will be closed when an active

connection from SmartSensor Matrix (or other source device) does not exist.

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.

The first four input mapping switches (1-4) for S4 are used to select a channel

group. A channel group indicates which input channels are mapped to the cards

output channels. If the first four input mapping switches are all off then the channel

group is software configurable. Otherwise, the pattern of these switches selects the

channel group (see Figure D.3). The same on/off pattern used for these dip

switches is also used when doing software selection of the channel groups using the

faceplate mode switch (Compare Figure D.3 to Figure D.6). This allows selection of

channels as high as channel 28. Contact Wavetronix technical support if you have

questions on how to select channel groups.

Figure D.3 – Channel Group Selection Using Input Mapping Switches (1-4)

The first three baud rate switches (1-3) for S5 are used to select the baud rate for

Bus 1. If the first three baud rate switches are all off then the Bus 1 baud rate is

software configurable. Otherwise, the pattern of these switches selects the Bus 1

baud rate.

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. These switches are only present in cases where the rack card needs

to output a voltage (wet) instead of a contact (dry). Please contact Wavetronix

customer support, if you have an application that requires a voltage output.

The voltage will normally be near VCC (typically 12 or 24 V). Then when the

contact closes, the output voltage will be near 0 V.

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.

The Red Flashing mode is used to reset the sensor to software factory defaults.

Please note that the position of the DIP switches may override software factory

defaults.

The Click! Supervisor software runs on PC and Pocket PC platforms. To learn how to

install the Click! Supervisor software, contact Wavetronix Technical Services or

consult the Click! user documentation. To help you select an individual rack card on

a multi-drop bus, Supervisor will auto-discover the device ID, model number and

description. You may wish to enter into the description field information pertaining

to rack slot position and detected traffic direction. For example, you can enter “NB

traffic slot 2”. Select the rack card you want to configure from the list (see Figure

D.10) and then select the driver you wish to use to configure the card from the list of

available drivers.

Once you connect to the rack card, Supervisor will recommend to upgrade the

embedded software if a newer version is available. The code files for an upgrade

should be installed in the “Click Home\Drivers\112” and “Click Home\Drivers\114”

directories. Contact Wavetronix customer service if you have questions regarding

the code or driver files in these directories. The last three pairs of numbers in the

filename (before the .txt suffix) indicate the release date of the code: YY.MM.DD

(year.month.day).

Note

When the DIP switches control the baud rates, you the specified baud rate is

displayed in the menu, but cannot be changed.

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). If the hardware switches prevent software configuration

for a specific setting, the user control will display the current setting, but will be

disabled and read-only.

Figure D.11 – Software Configuration

To setup or view the individual address of a rack card click on the Device ID control

(see Figure D.11).

The pin out of the Click! 112/114 backplane contacts is shown in Figure D.13.

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.

DC-voltage outgoing onto the T-bus is protected from electrical surges incoming

from the DC+ and DC- screw terminals. These terminals do not have reverse-

polarity protection, but assumes that all downstream devices will have proper

polarity protection. The surge protection meets the IEC 61000-4-S 4KV (Class 4)

specification.

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. When the surge is no longer fully functional, please contact Wavetronix

Technical Services for assistance.
