e Wavetronix SmartSensor HD trac sensor utilizes the latest technology to collect and
deliver trac statistics. e SmartSensor HD collects information through the use of a
24.125 GHz (K band) operating radio frequency and is capable of measuring trac volume and classication, average speed, individual vehicle speed, lane occupancy and presence. e SmartSensor HD uses what is classied as frequency modulated continuous wave
(FMCW) radar; it detects and reports trac conditions simultaneously over as many as 22
lanes of trac.
Once SmartSensor HD is installed, the conguration process is quick and easy. Aer installation, this unit will require little or no on-site maintenance and can be remotely recongured for optimal performance. is user guide outlines the step-by-step process of
installing and conguring the SmartSensor HD. Any questions about the information in
this guide should be directed to Wavetronix or your distributor.

Selecting a Mounting Location
Consider the following guidelines when selecting a mounting location:
Lane Coverage – Sensor mounting locations should be selected so that all monitored
lanes are within 6 to 250 . (1.8 to 76.2 m) of the sensor and run parallel with each
other. Multiple sensors should be considered if more than 10 lanes need to be simultaneously monitored. If lanes do not need to be simultaneously monitored, up to 22 lanes
can be congured for collection by a single sensor.
Parallel Lanes – When the sensor is used to collect both mainline and ramp data, the
pole position should be selected so that the on and o ramp lanes run parallel with
the mainline. If lanes are not parallel, installation of multiple SmartSensor HD units
should be considered.
Sensors on the Same Pole – When multiple sensors are mounted on the same pole,
they will not be subject to interference if they are congured to operate using dierent
RF channels and are separated vertically by a few feet. e higher sensor would typically be used for the lanes farther from the pole in order to minimize occlusion.
Sensors on Opposing Poles – SmartSensor HD units facing each other on opposing
poles should operate on dierent RF channels and be separated by a 70-. (21.3-m)
lateral oset, if possible.
Line of Sight – e SmartSensor HD is designed to work accurately in the presence of
barriers, but in general if there is an alternate mounting location that would avoid any
type of structural occlusion, this is preferred. Avoid occlusion by trees, signs, and other
roadside structures.
Neighboring Structures and Parallel Walls – To eliminate the risk of performance
degradation, the sensor locations should have a 30-. (9.1-m) lateral separation from
overhead signs, overpasses, tunnels, parallel walls, and parallel parked vehicles in order
to avoid multiple reection paths from a single vehicle. is separation removes the
objects from the antenna pattern of the sensor. In practice the sensor has been mounted
much closer to reecting objects with minimal impact in sensor performance. For ex-
INTRODUCTION SMARTSENSOR HD USER GUIDE 7
ample, sensors mounted on gantries have successfully met customer requirements when
using a 3-foot extension arm to laterally separate the sensor from the structure. Please
talk with a Wavetronix Technical Support representative about your specic situation.
Mounting Height – e mounting height should be based upon the oset from the
lanes of interest. For each oset, the minimum, maximum, and best heights are shown
in Table 1.1, found in Chapter 1. In general, the range of recommended heights is between 9 and 50 . (2.7 to 15.2 m).
Mounting Oset – e minimum recommended oset (distance from the sensor to
the edge of the rst lane of interest) is 6 . (1.8 m).
Arterial Locations – Sensor sites on arterials or other roadway segments with regulat-
ed stop lines should be selected at midblock positions to increase accuracy by avoiding
positions at which vehicles are oen stopped in front of the sensor.
Freeway Locations – e SmartSensor HD is oen used at permanent ATR (auto-
matic trac recorder) stations. e number of stations along a single roadway and the
distance between stations should be selected to achieve adequate levels of statistical
condence. Permanent ATR stations, which are selected to cover interstate, principal
arterial, and other national and state highways, are used to establish seasonal adjustment factors for count data from temporary collection sites (see Figure I.1).

Cable Lengths – Ensure that you have sucient homerun and sensor cabling. Cables
can be as long as 600 . (182.9 m) if they’re using 24 VDC operation and RS-485 communications; for longer connections, alternate wired and wireless options should be
considered.
Signaling Delay – Aer a vehicle passes in front of the sensor there will be a slight
delay before the data for that vehicle is sent from the sensor. In a time-sensitive application—for instance, to supply a dynamic message sign with per vehicle warning
messages—it will be necessary to ensure the sensor is suciently far upstream from
the sign that the system has time to collect the data, process it, and send it to the sign
by the time the vehicles reach the problem area. For specics about signaling delay,
see Appendix E.

14 CHAPTER 1 INSTALLING THE SMARTSENSOR HD
Attaching the Mount Bracket to the Pole
Before attaching the mount bracket to the pole, rst make sure that your cables are long
enough to reach the sensor and to stretch across the distance from the sensor to the cabinet.
Follow the steps below to correctly attach the mount to the pole (see Figure 1.2):
1 Insert the stainless steel straps through the slots in the mount bracket.
2 Position the mount bracket on the pole so that the head of the mount is pointing to-
wards the middle of the lanes of interest.
3 Tighten the strap screws.
Note
The sensor will need to be adjusted later, to fine-tune the alignment, so be sure to
keep the straps adjustable.
Figure 1.2 – Attaching 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 backplate with the holes in the mount bracket. e con-
nector at the bottom of the unit should be pointing towards the ground.
2 Place the lock washers onto the bolts aer the bolts are in the mount bracket holes.
3 read on the nuts and tighten (see Figure 1.3).
CHAPTER 1 INSTALLING THE SMARTSENSOR HD 15
Note
Do not over-tighten the fasteners.
Figure 1.3 – Attaching the Sensor to the Mount Bracket
Aligning the Sensor to the Roadway
Use the following steps to correctly mount and align the SmartSensor HD:
1 Tilt the sensor down so that the front is aimed at the center of the detection area (see
Figure 1.4).
Figure 1.4 – Up-and-down Positioning
2 Adjust the side-to-side angle so that it is as close to perpendicular to the ow of trac
as possible (see Figure 1.5).
16 CHAPTER 1 INSTALLING THE SMARTSENSOR HD
Note
The side-to-side alignment will eventually be fine-tuned for better accuracy using
SmartSensor Manager HD (SSMHD). That step will be addressed in Chapter 6, after
SSMHD has been installed.
Side-to-side alignment should
be perpendicular
Figure 1.5 – Side-to-side Positioning
Applying Silicon Dielectric Compound
Use the following steps to correctly apply the silicon dielectric compound:
1 Tear the tab o of the tube of silicon dielectric compound.
2 Squeeze about 25% of the silicon into the connector at the base of the SmartSensor HD
(see Figure 1.6). Be sure to wipe o any excess compound.
Figure 1.6 – Applying Silicon Dielectric Compound
CHAPTER 1 INSTALLING THE SMARTSENSOR HD 17
Connecting the Cable
e sensor connector is keyed to ensure proper connection; once you have plugged the
cable connector into the sensor connector, simply twist the cable connector clockwise until
you hear it click into place. 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 (see Figure 1.7).
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.
Figure 1.7 – Sensor Connector
e service end of the cable has a +DC and GND for a power supply of 12 to 24 VDC. Two
communication ports (either RS-232 or RS-485) are available to connect the SmartSensor
HD to a modem or other communication device. Typically, one RS-485 and one RS-232
port are available.

Once the sensor is installed, it will need to be wired for power and surge protection. Wavetronix Click products allow you to quickly and easily include power and surge protection
in your sensor application. Please refer to the Click quick-reference guides for more comprehensive product instructions.
ere are several ways your sensor might be set up:
A two-part installation, with components in two areas: rst, a pole by the road holds
your sensor plus a pole-mount box with a surge protector inside. Second, a main trac
cabinet holds power and communications devices. e cabinet and pole are connected
via a homerun cable that runs underground.
Note
This chapter assumes the box and cabinet are connected by an underground cable
run, but in certain circumstances they might not be.
20 CHAPTER 2 CONNECTING POWER AND SURGE
A single-part installation, with all components on the same pole. is pole holds your
sensor. Power and communications devices (most likely wireless) are in a pole-mount
box or there is a trac cabinet at the base of the pole; either way there is no underground cable run. Power comes from the pole itself or from a battery and/or solar
panels at the pole.
How you set up the devices in this chapter will vary depending on which of these installations you are using.
Connecting Lightning Surge Protection
e sensor should be connected to at least one surge protection device. e Click 200 and
equivalent devices are designed to prevent electrical surges along cables from damaging the
sensor and/or the cabinet. It is also a convenient spot to terminate the cable coming from
your sensor, as it has terminals for all the wires.
Note
If you choose not to use surge protection in your installation, please contact Wavetronix Technical Services for assistance.
If you are using the one-part installation option—no underground cable run—put a Click 200
in the pole-mount box/trac cabinet (whichever is being employed) as a termination point
for the cable from the sensor, and as a way to protect the box/cabinet. When there is no underground cable run, it is safest practice, as well as Wavetronix standard procedure, to connect
the cable from the sensor in the UNPROTECTED side of the Click 200.
1 Install a Click 200 in the pole-mount cabinet/trac cabinet by snapping it onto the
DIN rail. Your power and communications devices will most likely also be on this DIN
rail; make sure the Click 200 is connected to them via wires or the shared communication bus (connecting power will be covered later in this chapter; for how to connect to
communications devices, see the Click 100–400 Series User Guide).
2 Wire the cable from the sensor to the UNPROTECTED side of the Click 200.

Figure 2.1 – Using a Single Click 200
Note
The dierent cables available and how to wire them into the Click 200 will be covered
later in this section.
If you are using the two-part installation option, you’ll have an underground cable run as
part of your installation, connecting the power and comms devices in the main trac cabinet to the pole-mount box and sensor. When there is an underground cable run, it is safest
practice, as well as Wavetronix standard procedure, to use two Click 200s, one on each end
of the cable: one in the main trac cabinet and the other in the pole-mount cabinet. Both
ends of the cable should be connected to the UNPROTECTED side of their Click 200s. is
is important because the underground cable run will be susceptible to surges caused by
lightning striking the ground near it.
If this run is shorter than 600 . (182.9 m), you can use a Wavetronix cable; see Appendix
D for more on cable lengths.
1 Install one Click 200 device in a pole-mount cabinet on the same pole as the sensor
being protected. Install it by snapping it onto the DIN rail.
2 Connect the cable from the sensor to the PROTECTED side of this Click 200. is
cable should be kept as short as possible.
3 Install another Click 200 in the main trac cabinet. You will likely have power and com-
munications devices in this cabinet; make sure the Click 200 is connected to them via wires
or the shared communication bus (connecting power will be covered later in this chapter;
for how to connect to communication devices, see the Click 100–400 Series User Guide).
4 Connect the pole-mount box and the main trac cabinet by running a cable from the
UNPROTECTED side of the Click 200 in the pole-mount box to the UNPROTECTED
side of the Click 200 in the main trac cabinet.

Wiring the Click 200
ere are two cables that may be used with your sensor, the 8-conductor cable and the
9-conductor cable. Which one you use is based largely on the connector on your SmartSensor HD—that is, the connector where the cable will be plugged into the sensor.
ere are two dierent connectors that may be found on a SmartSensor HD:
e 10-pin connector is used with the SmartSensor HD. It currently only comes in-
stalled on the 8-conductor cable.
e 26-pin connector is used with SmartSensor HD Legacy and retrotted HDs. It can
be installed on the 8-conductor cable or the old 9-conductor cable.
Note
There may be compatibility issues if you use a 8-conductor/26-pin connector cable
with a SmartSensor HD that was manufactured in or before 2008. Contact Wavetronix Technical Services for details and assistance.
e wiring for these two cables is almost identical; the dierences are pointed out on the
following page.
Note
If you have an underground cable run that stretches more than 600 ft (182.9 m), you will
likely need to use a dierent cable; in that case the colors won't match the figure below.
CHAPTER 2 CONNECTING POWER AND SURGE 23
e Click 200 contains three terminal connectors on both the top and the bottom of the
module (see Figure 2.3). e terminal connectors are removable and are red-keyed, allowing each connector to plug into only one specic jack. is both simplies the wiring
process and reduces the possibility of wiring errors.

Wiring to Earth Ground
All Click 200 devices should be mounted on a DIN rail that is connected to earth ground
either through an earth-grounded chassis or a 16 AWG or larger grounding wire attached
to a 7-. (2.1-m) grounding rod. Follow the steps below to correctly wire to earth ground:
24 CHAPTER 2 CONNECTING POWER AND SURGE
1 Connect the grounding wire from either the DIN rail or a GND screw terminal on the UN-
PROTECTED side of the Click 200 to the lug bolt on the inside of the pole-mount cabinet.
2 Connect another grounding wire from the exterior lug bolt to earth ground (see Figure 2.4).

of power, but that will usually not be necessary in an installation such as the one outlined
below.) e Click 230 helps limit current surges on the power lines; the Click 210 interrupts
power during overload conditions and provides a convenient way to turn power on and o.
e power plant will either be in a pole-mount box or in a main trac cabinet. If it’s in a
trac cabinet, the power will be sent to the pole via an underground cable run. How to install the power plant and then wire to a Click 200 will be covered in the rest of this section.
It should be noted that if you have ordered a Wavetronix preassembled cabinet, all of this
wiring and installation will already be done.
CHAPTER 2 CONNECTING POWER AND SURGE 25
Note
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 trac 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.
Wiring in AC
e rst step is to get AC power into the enclosure. (Sometimes the power source is actually
DC; to see Wavetronix’s selection of DC power modules, see the Click 100–400 Series User
Guide.) If you’re using a main trac cabinet, wire from its power source; if you’re using a
pole-mount box, the power lines or cable can be brought in through the conduit on the
bottom-le.
Note
Make sure power to AC mains is disconnected while wiring AC input.
Wiring the Click 210
e rst device in the power plant, as seen in Figure 2.5, is the Click 210. is is a compact
circuit breaker DIN rail device designed to interrupt an electric current under overload
conditions. e breaker is trip-free and can be easily reset aer a current interruption by
pushing the reset button.

To add a Click 210 circuit breaker and switch (see the le side of Figure 2.5):
1 Mount the Click 210 onto the DIN rail.
2 Connect the line conductor (usually black) from the AC terminal block or cord in to
either side of the module.
3 Wire out of the other side.
Note
For ease in troubleshooting, it is recommended that you follow the wire color scheme
outlined in this chapter.
Wiring the Click 230
e next device in the power plant is the Click 230, which is the AC surge protector (see
Figure 2.5). To install:
1 Mount the Click 230 onto the DIN rail next to the Click 210.
2 Connect the line conductor (black) from the Click 210 to terminal 5 on the IN side of
the Click 230.
CHAPTER 2 CONNECTING POWER AND SURGE 27
3 Connect the neutral (usually white) wire from the AC terminal block or cord to the
terminal marked 1 on the Click 230.
4 Connect the ground wire from the AC terminal block or cord to the terminal marked
3 on the Click 230.
5 Connect an outgoing and protected line wire to the terminal marked 2 on the Click
230. e line wire should be black.
6 Connect an outgoing and protected neutral wire to the terminal marked 6 on the Click
230. e neutral wire should be white.
e terminal blocks 3 and 4 are directly bonded via the metal mounting foot of the base
element to the DIN rail. ere is no need for any additional grounding between terminals
3 and 4 and the DIN rail.
Wiring the Click 201/202
e nal device in the power plant should be either a Click 201 or 202 (as shown in Figure
2.5). ese are AC to DC converters, also occasionally called the power supplies. As noted
above, the dierence between the two is that the Click 201 outputs 1 A and the Click 202
outputs 2 A (the Click 204 outputs 4 A but will probably not be needed for an HD installation). Choose which device suits your installation best, then follow the steps below to install
it (see Figure 2.6):
1 Mount the Click 201/202 onto the DIN rail next to the Click 230.
2 Connect the line (black) wire from the Click 230 into the L screw terminal on the top
of the Click 201/202.
3 Connect the neutral (white) wire from the Click 230 to the N screw terminal to the top
of the Click 201/202.
Figure 2.6 – Wiring AC Power into the Click 201/202
Note
The NC screw terminal is not connected internally. Connecting a wire to a no connect
(NC) terminal simply gives it a convenient termination point.
28 CHAPTER 2 CONNECTING POWER AND SURGE
To wire the newly converted DC power out of the Click 201/202:
1 Connect a +DC conductor (usually a red wire) to the + screw terminal on the bottom
of the Click 201/202 (see Figure 2.7).
2 Connect a -DC conductor (usually a black wire) to either of the – screw terminals on
the bottom of the Click 201/202.
Figure 2.7 – Wiring DC Power Out of the Click 201/202
Note
Do not wire into the screw terminal marked DC OK; it provides only 20 mA and should
be used only for monitoring the power supply.
e screw terminal connectors on the top and bottom of the module are removable to simplify wiring and are red-keyed, allowing the connector to plug into only one correct jack.
Connecting the Power Plant to Your Installation
Now the power plant is complete and you have reliable, safe DC power. e next step is to
get that power to the rest of the installation.
If the power plant is in a pole-mount box, this involves getting that power onto the T-bus; from
there it will power any communication devices that may be on it. It will also power the Click 200,
which will send the necessary 10–30 VDC, along with communications, to the sensor.
If the power plant is in a main trac cabinet, this also will involve getting DC from the
power plant on the T-bus; from there it will power any communication devices on that bus.
It will also power the Click 200, which will send that power, along with communications,
along the homerun cable to the Click 200 in the pole-mount box. at Click 200 will put
the power (and communications) onto the T-bus, powering any communication devices
that may be on it. It will also send the necessary 10–30 VDC, along with communications,
to the sensor.
CHAPTER 2 CONNECTING POWER AND SURGE 29
To put power on the T-bus, you will rst need to connect a 5-screw terminal block to the
end of the T-bus, then follow the steps below to wire DC to it:
1 Connect +DC (red) from the Click 201/202 to the top screw terminal on the 5-screw
terminal block.
2 Connect –DC (black) to the second screw terminal.

connecting communication.
You can also wire DC to the Click 200 itself; it will then put that power on the T-bus. If you’d
like to do that, follow these steps:
1 Connect +DC (red) from the Click 201/202 to the +DC screw terminal.
2 Connect -DC (black) to a GND screw terminal.

Wiring Communication
e last thing to do is decide how to communicate with the sensor. How you do this will
vary based on your installation. If your sensor is connected to a Click 200 in a pole-mount
30 CHAPTER 2 CONNECTING POWER AND SURGE
box, and you want to access that sensor from a main trac cabinet or from the trac operations center, you will need some kind of communication between the two spots: either with
the homerun cable, which can carry both RS-232 and RS-485 communications, or by using
a Wavetronix Click communication device.
Wavetronix has a variety of wired and wireless communication devices, such as the Click
301 serial to Ethernet converter, which lets you communicate with the sensor via Ethernet,
or the Click 400, which is a 900 MHz radio that communicates wirelessly with other radios.
See the Click Catalog, Click Series User Guide, or ITS Designer Training Guide for more
information.
e Click 200 has several ports for other methods of communication. e faceplate has a
DB-9 port you could connect to for RS-232 communication. ere are also several RS-485
connections:
T-bus backplane: puts RS-485 on the T-bus. Because the Click 200 is connected to the
sensor, this T-bus connection means the sensor, the Click 200, and any other device on
the T-bus all communicate with each other.
RJ-11 connector on the faceplate for connecting to contact closure devices, if desired.
Note
The Click 200 does not convert RS-232 communication to RS-485. It simply provides
surge protection for these two independent connections.

Advanced Settings
Below is a list of some advanced settings also available on this screen:
Flow Control – Is usually only used if you are connecting through a RS-232 device that
requires hardware handshaking.
Timeout – Allows you to set an additional amount of time (in milliseconds) that
SSMHD will wait for a response when communicating with the sensor.
Note
When connecting directly from a computer running SmartSensor Manager HD to a
SmartSensor HD unit (with no modem in between), you should not attempt to connect unless the Flow Control setting is set to None. Otherwise you may not be able
to successfully connect.
Internet Connection
e SmartSensor HD can be connected to the Internet, allowing access to the sensor from
anywhere with Internet access. Below is a list of a couple ways to connect the SmartSensor
HD to the Internet:
Serial to Ethernet Converter – e SmartSensor HD can be connected to a local area
network (LAN) by using a serial to Ethernet converter. As an option, the SmartSensor
HD 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.
Internet Service Providers – Cellular providers of wireless Internet services maintain
networks in most metropolitan areas in the United States and coverage continues to
expand. e SmartSensor HD can be equipped with an optional external modems—for
example, CDMA, GMS or GPRS—and assigned an Internet address on these networks.
Use the steps below to connect to the SmartSensor HD using an Internet connection:
1 Click on the Internet icon (see Figure 4.3)
2 Enter the IP address or URL of the sensor of interest in the Network Address eld. e IP
address consists of four numbers ranging from 0–255 separated by dots. Enter the IP address assigned to either the CDMA modem or the Click 301 serial to Ethernet converter.
3 Enter the port number assigned to the CDMA modem or the Click 301 serial to Eth-
ernet converter in the Port eld. is will be an integer value in the range of 0–65536.
e Click 301 port number automatically defaults to 10001.
4 Click the Connect button to connect to the sensor.
40 CHAPTER 4 COMMUNICATION
Figure 4.3 – Internet Connection
e Timeout eld allows you to set an additional amount of time (in milliseconds) that
SSMHD will use when communicating with the sensor.
Virtual Connection
A virtual connection allows you to use the SSMHD soware without being connected to an
actual sensor. Making a virtual connection can be useful for the following reasons:
To view a saved sensor setup le.
To demonstrate functionality for dierent applications.
To review how the soware works.
Use the following steps to make a virtual connection:
1 Click the Virtual button (see Figure 4.4).
2 Select or create a virtual sensor le (.sim) by clicking the magnifying glass icon.
3 Click the Connect button.

Additional Settings
e Trac Properties section contains the following settings:
Style – is section allows you to set random or patterned trac for the simulator.
Flow – Allows you to set the trac volume for the simulated trac.
Average Speed – Allows you to set the average trac speed for the simulated trac.
Virtual Sensor File
Since a virtual connection is not made to an actual sensor, a virtual sensor le (.sim) is
used to save the conguration settings much like an actual sensor’s ash memory. If you are
making a virtual connection for the rst time, you will need to create a virtual sensor le by
clicking on the magnifying glass icon and entering a le name.
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.
Backing up a virtual sensor le will change the le to a sensor setup le (.ssc) that can be
restored to an actual sensor. To convert a sensor setup le to a virtual sensor le, make a virtual connection and then use the Restore Sensor Setup tool in the Too ls menu. To convert
a virtual sensor le to a sensor setup le, use the Back-up Sensor Setup tool.
Viewing Connection Information
Once a connection is made to the SmartSensor HD, the main menu will appear and all

Units – Allows you to display either English (mph/feet) or metric (kph/meters) units.
Date & Time – To sync the sensor date and time with the computer, click the Sync to
this computer checkbox. e sensor itself stores time in Coordinated Universal Time
(UTC), formerly known as Greenwich Mean Time (GMT), and does not account for
daylight saving time. SSMHD uses the local setting of the computer it is running on to
display the date and time in local units.
Example
If someone in Pacific Standard Time (PST) connect to a sensor and synchronizes the
time, then when someone in Mountain Standard Time (MST) connects to the same
sensor the time will be correctly displayed as MST. If the settings on either PC adjusts
for daylight savings, then this adjustment will also be correctly displayed.
Ports Tab
e Ports tab contains the following settings (see Figure 5.2):
Figure 5.2 – Ports Tab
CHAPTER 5 SETTINGS 49
Green highlight – is indicates the communication link (port) on which SSMHD is
connected.
RS-485 – Allows you to set the baud rate for RS-485 communication. e Response
Delay setting is used to congure how long the sensor will wait before responding to
a message received. is is useful for some communications devices that are unable to
quickly change transmission direction. e default value is 10 milliseconds.
e Termination checkbox allows you to electronically turn RS-485 communication
bus termination on or o. Only the end devices on a RS-485 bus should be terminated.
In general, the termination can be le unchecked until a multi-drop bus becomes overloaded.
RS-232 – Allows you to set the baud rate for RS-232 communication. e Response
Delay setting works the same as the RS-485 section.
e HW Handshaking checkbox should be selected if you are connecting your sensor to
an RS-232 device (such as some modems). ese devices sometimes require ow control
handshaking because they cannot keep up with the data rates of higher-performance
devices like personal computers and SmartSensor HD. SmartSensor Manager HD and
SmartSensor HD have built-in support for RS-232 ow control hardware handshaking;
this support allows the SmartSensor HD and SmartSensor Manager HD to work with
these slower modem connections. Table 5.1 gives a brief description of each RS-232 line.
Line Description
TX Transmit data line
RX Data receive line
RTS Request to send flow control hardware handshaking line
CTS Clear to send flow control hardware handshaking line
Table 5.1 – RS-232 Lines
In order to use hardware handshaking, the sensor’s RTS and CTS signals must be properly
connected. If the Flow Control option under the Serial connection screen is set to Hard-
ware, you will not be able to connect if the sensor’s HW handshaking setting has been
previously turned o. e reason you cannot connect is that the sensor’s RTS line is not
asserted; as that line is connected to the computer’s CTS line, the computer will not forward
data messages it is given by SmartSensor Manager HD. To successfully connect, simply
change the Flow Control setting to None.
Outputs Tab
e Outputs tab contains the following settings (see Figure 5.4):
50 CHAPTER 5 SETTINGS
Source – Allows you to determine what information is reported. ere are two options:
Antenna reports data as detected by the antenna in the sensor, and Diagnotic creates
detection events for testing and training purposes.
Note
If the sensor is in Diagnostic or Replay mode, it will not detect live trac.
Figure 5.3 – Outputs Tab
RF Channel – Displays which radio frequency channel the sensor is transmitting on.
Using multiple sensors in close proximity will require each sensor to be set to a dierent RF channel (see the introduction for more information about mounting sensors in
close proximity).
Loop Emulation – is section allows you to set loop size and spacing to allow Smart-
Sensor HD to emulate dual loops. e settings changed on this screen will apply to all
congured lanes. ese settings are read by a Click contact closure device and used so
that the contact closures can be properly timed to emulate a given loop size and spacing. e loop size is also used by the sensor in the occupancy calculation. For example,
larger loop sizes will result in higher occupancy numbers in the interval data. However,
adjusting these parameters will not modify the reported vehicle length or speed (see
Chapter 6 of this user guide to accomplish these tasks).
Legacy Protocols – e SS105 protocol must be selected when being used with Click
communication and contact closure devices (it is not necessary if you are only using
Click surge and power devices). is does not turn o native SSHD protocol.
e RTMS (X3): ID checkbox allows you to turn RTMS protocol emulation on or o;
only a subset of RTMS data reporting commands are emulated. is does not turn o
native SSHD protocol. e RTMS ID eld will only be editable if the RTMS Protocol
checkbox is selected.
CHAPTER 5 SETTINGS 51
Note
If you are using a SmartSensor HD in an RTMS-based system, there are two ways
to collect data from the sensor. If your system is set up to poll the sensor, the RTMS
protocol must be turned on so the sensor can respond to RTMS commands. If your
system is simply listening for data pushes from the sensor, the RTMS protocol does
not need to be turned on. See Chapter 7 for more information on data push.

Configuration
e Conguration screen can be used to automatically or manually congure the roadway,
manipulate lanes, and control how you see the information onscreen. To reach the screen,
click the Conguration button.
Sensor Alignment
e sensor should be properly aligned before beginning lane conguration, so SSMHD includes
an alignment feature that gives visual conrmation when the perpendicular alignment of a sensor is correct (see Figure 6.2). SSMHD gives you three dierent ways to check sensor alignment:
the arrow coming out of the sensor; the color on the detected vehicles; and in the sidebar.
Once you open the Conguration screen, you should see alignment arrows. If there are no
alignment arrows, click on the magnifying glass icon and then select Show Alignment.
Figure 6.2 – Sensor Alignment
Adjust the sensor according to the arrow displayed in the Conguration window. A green
CHAPTER 6 LANES 55
arrow means the sensor is correctly positioned for optimal performance; a yellow or red
arrow means the sensor is NOT correctly aligned with the roadway.
Note
In order for the sensor alignment tool to function properly, trac must be flowing
freely. Also, if the sensor is not already aligned close to perpendicular to the flow of
trac, the sensor alignment tool will display a question mark indicating that the
sensor is too far out of alignment for the tool to function properly. Realign the sensor
manually and then fine-tune the alignment with the tool. After each adjustment of
the sensor, several vehicles must pass before the alignment tool's output is valid.
It may be dicult to align the sensor if there are non-parallel lanes of trac. In this case,
mark the non-parallel lanes as Inactive or Excluded in the lane conguration screen, and
the sensor alignment tool will ignore vehicles traveling in these lanes.
Note
In cases where trac lanes are not exactly parallel, the percentage of vehicles with
reported speeds may decrease in the lanes that are skewed.
Auto-Configuration
One of the advantages of the SmartSensor HD is the fast and simple lane auto-conguration function, where the sensor automatically congures the roadway and sets up the lanes
based on passing trac.
Follow the steps below to automatically congure the SmartSensor HD (see Figure 6.3):
1 Once the Conguration window appears, click the Tools icon and select Clear Edit
Area.
2 Click the Tools icon again and then click Restart Auto Cfg.

Depending on where the sensor is mounted and on the amount of trac, the conguration
process could take a few minutes. Once the SmartSensor HD has detected vehicles and
created the appropriate lanes, click OK and a window will appear asking you to save the
changes to the conguration. Click Yes and the conguration will be saved.
Follow the steps below if only a portion of the automatically dened lanes are desired:
1 Click anywhere in the Conguration screen.
2 Check the Hide Auto-Lanes box and the automatically congured lanes will disappear.
3 Click on the desired automatic lane in the sidebar (when the sidebar is set to 1) and the

Shoulder Area
Click in the shoulder and the Shoulder Area window will appear, allowing you to add or
exclude the shoulder you just clicked on (see Figure 6.10). is is useful when aligning the
sensor when there are non-parallel lanes in its eld of view. Alternatively, it can also stop
events from being generated in any non-lane areas. In the Verication screen, and when the
sensor is reporting data, any vehicles in non-lane dened areas will not be shown regardless
of whether the area is excluded or not. Click in an excluded area and the Excluded Area
window will appear, allowing you to include the area again.
Figure 6.10 – Edit Area Window
Lane Window
Click anywhere on a lane and the Lane window will appear, allowing you to change the
name, direction and activity of a lane (see Figure 6.11). SSMHD uses “LANE_xx” as the default lane name where “xx” is the number of the lane in range, beginning with “LANE_01.”
When a new lane is added, all lanes with the default lane name format will automatically be
renamed to indicate their increasing number in range. If this is not desired, the lane names
can be changed in any way; lane names are case and symbol sensitive and are limited to
eight characters.
Note
If you rename a lane with a new lane number, the software won't let you leave the
name in the form of LANE_XX. One easy way to get around this is to lowercase the
word "LANE." For example, to change the lane currently numbered as 1 to number 6,
change the name from LANE_01 to Lane_06.
For RTMS and Z4 data push types, the mapping of the lanes may be changed using the notation #xx (e.g. #08), where 08 is a lane number between 1 and 99. In this case, ALL lanes in
the conguration must be assigned a lane number using the #xx notation in order for the
new lane mapping to take eect.
CHAPTER 6 LANES 61
Figure 6.11 – Lane Adjustment Window
e direction button allows you to set the direction for the lane—Le, Right or Bidirectional. e direction chosen determines what data is shown: if Right is the set direction for a
lane, only trac going to the right will be detected; and if Le is the set direction for a lane,
only trac going to the le will be detected (when Direction Protection is on). If the lane is
set to Bidirectional, data will be reported for trac going both directions. is is useful for
lanes that change direction depending on the time of day. Selecting Bidirectional is essentially the same as turning o Direction Protection for that lane (see the Lane Adjustments
section in Chapter 6 for more information on Direction Protection).
Note
All detected vehicles are shown on the Lane Configuration screen, regardless of direction.
Click the Exclude button to exclude a lane (the lane will turn red once it has been excluded) or click the Delete button to delete a lane. Excluded lanes will not be congured and
SSMHD will stop showing events in those particular lanes. Click the excluded lane and click
the Include Area button to include the lane.
e Lane window also allows you to set a lane as active or inactive. Inactive lanes are useful
when a lane has been correctly congured and tuned, but data reporting for the lane is not
desired. By making the lane inactive instead of deleting it, the lane may be turned on at any
time and will retain the proper conguration and tuning.

ume, speed or class sidebars. Click the Play button to add new vehicles to the running totals
for all sidebars; click the Stop button to reset all volume, speed and class numbers to zero.
Lane Adjustment
Lane performance can be adjusted by clicking anywhere inside a lane and using the Lane
Adjustment tool (see Figure 6.14). e drop-down list allows you to adjust lane volume, detection, speed, length, extension time or direction protection. To return to default settings,
select Set Defaults from the drop-down list and click the OK button. Each lane adjustment
is independent of other lanes; setting one lane back to defaults using the Set Defaults op-
tion will not aect the other lanes.
Figure 6.14 – Lane Adjustment Window
Volume – is setting should be adjusted rst when a problem with count accuracy is ob-
served. e default is 100%. is setting adjusts the aggressiveness of trac radar-specic
algorithms and is not an arbitrary scale factor. By increasing the percentage by 10% to
15%, you are likely to begin to increase the number of detection, and by decreasing the
percentage by 10% to 15%, you are likely to begin to decrease the number of detections.
Small adjustments of only 1% or 2% may actually have no impact on the detection performance. Practical values for this setting are typically between 20% and 190%. If the volume lane adjustment is below 20%, many detections in that lane will probably be missed;
if it is set greater than 190%, many false detections will probably occur.
Detection – Raises or lowers the threshold for detecting vehicles. e sensor auto-
matically determines where the threshold will be placed, and then adds in this tuning
parameter. Entering a larger number will result in fewer detections; entering a small
number will result in more detections. e default is 0 dB.
Note
Changing the detection tuning parameter can drastically eect vehicle detection.
64 CHAPTER 6 LANES
Speed – Raises or lowers the speed calculated for all vehicles in each lane. e sensor
calculates the speed, and then multiplies the speed by this factor. e default is 100%.
Length – Increases or decreases the length for all vehicles in each lane. e sensor
calculates the length and then adds the length factor. e default is 0 (feet or meters
depending on sensor units used). Since the occupancy metric that is reported in the
interval data is calculated using length, a change in the length tuning parameter will
also change the occupancy that is reported. See page 69 for the equation that is used to
calculate occupancy and for a more detailed explanation.
Extension Time – Changes the extension time, which the sensor uses to prevent ve-
hicles with trailers from being broken into multiple detections. A longer extension time
will prevent this, but can lead to multiple vehicles being merged into a single detection.
e sensor automatically determines the extension time and then multiplies by this
factor. e default value is 100%.
Note
There must be a minimum of 5.5 ft (1.68 m) between vehicles in order for them to be
detected as separate vehicles. This separation requirement may increase as vehicle
speeds increase.
Direction Protection – Allows you to turn Direction Protection on or o. When Di-
rection Protection is on (default), data will be shown only for vehicles that are going
in the direction set for that lane. For example, if a lane is set for trac moving north,
any trac in that lane that may be moving south will be ignored. However, if the sensor determines that most vehicles are going a direction dierent from the one that was
congured (e.g. during hurricane evacuation), the sensor will begin reporting vehicles
going all directions. Turning o Direction Protection allows SSMHD to always report
data from vehicles going both directions.
Note
If a lane has been configured to be bidirectional, Direction Protection will be disabled.

ere are up to 8 class bins, 15 speed bins and 2 direction bins; all or none of these bins may
be simultaneously congured and the number of congured bins will impact the storage
capacity, as well as data download time. e term “bins” refers to classications of vehicles
based on their length, speed or direction. Once bins are set, data can be collected for these
groupings of vehicles; for instance, the sensor can count for you how many passing vehicles
are driving between 90 and 100 mph.
Adding more bins causes data records to be larger, meaning that your sensor’s onboard
CHAPTER 7 DATA 67
memory lls up faster and must be downloaded from more oen. See the Storage section of
this chapter for more information on how to gure out how many days’ worth of memory
your sensor has based on its current settings.
Interval
Interval data refers to the data collected about all the vehicles that pass the sensor in a set
amount of time. is interval of time should be carefully chosen because the length of it
aects how long the sensor can store data onboard. A shorter interval means the sensor
records data more oen, which means that the sensor’s onboard memory lls up faster. A
longer interval means you can leave the sensor alone for longer periods of time. Ultimately
the interval size should be selected to meet the requirements of your application. For example, in real-time applications, onboard storage capacity may not be a concern at all and
the data may need to be aggregated over short periods of time (20 seconds) to reduce reporting latency. To set the interval, click anywhere inside the Interval eld and use the up/
down arrows to change the interval (see Figure 7.2). See the Storage section in this chapter
for more information.
Once you download the interval data, you will have the following information for each lane
or approach:
Name – Displays the name of each lane or approach. To change the name, go to the
Lane Conguration screen or the Approaches screen.
Volume – Shows the number of vehicles detected during the interval.
Occupancy – Gives the percentage of time during the interval that the detection zone
was occupied.
Occupancy is calculated by summing the durations of all vehicles in the interval and dividing that quantity by the length of the interval. For example, if the interval length is ve
minutes and 100 vehicles pass the sensor during the interval with a duration of 0.09 seconds
each (sum of the durations is 9 seconds), then the occupancy for that interval would be
calculated by dividing 9 seconds by 300 seconds, which is 3%.
Rather than using the uncalibrated detection duration, or the time that a vehicle is in the radar beam, in the occupancy calculation, a more accurate occupancy measurement is made
by rst calculating the vehicle length and then converting that to a duration by adding the
simulated loop size and dividing by the speed. Occupancy based on vehicle length is more
accurate than occupancy based on uncalibrated detection duration because the vehicle
length calculation removes the eect of the antenna beam widening as it gets farther from
the sensor. e occupancy calculation is shown in the following equation:

68 CHAPTER 7 DATA
Note
A change to the length tuning parameter for a given lane will aect the occupancy for
that lane since vehicle length is used in the occupancy calculation.
Speed – Indicates the average lane speed during the interval. A negative number will be
reported for speed in the following cases: (1) e lane was congured to the le or right
and Direction Protection was on, but trac was traveling against the congured direction,
indicating that the direction of the lane has switched. is is useful in hurricane evacuation
scenarios. (2) e lane was congured to the le or right and Direction Protection was
o, but more vehicles were detected traveling against the congured direction than were
detected traveling with the congured direction for the given data interval.
Unlike per vehicle data, lanes that are congured as bidirectional will always report
positive average speeds in the interval data.
85% – Shows the 85th percentile speed. Eighty-ve percent of the vehicles in the inter-
val were going this speed or slower.
Headway – Displays the average time separation between vehicles detected during the
interval, measured from front bumper to the front bumper of the following car.
Gap – Shows the average time separation between vehicles detected in the interval,
measured from the back bumper of the rst car to the front bumper of the second.
Classes – Refers to length-, speed-, and direction-based bins (see the Speed and Class
sections later in this chapter). ese columns show the number of cars from each
length, speed and direction class that were detected during the interval.
Speed
Speed bins allow you to see how many vehicles are traveling within specied speed ranges.
You can have up to 15 speed bins. Click the button in the Speed window to set up your
speed bins (see Figure 7.3).
Figure 7.3 – Speed Bins
Here, you are assigning a minimum and maximum speed value for each bin. For example,
the maximum speed value for bin 2 is 26 mph. If a vehicle is traveling 25 mph, then that
CHAPTER 7 DATA 69
vehicle will be placed in bin 2. If a vehicle is traveling 27 mph, then that vehicle will be
placed in bin 3.
You can change the speeds by clicking on a bin and using the +/- buttons to either increase
or decrease the value.
Class
e class bins allow you to classify vehicles by ranges of lengths. If you’re not sure what
lengths to use, consult your own agency’s guidelines. If your agency has no set classication
scheme, you can look to the measurements in Table 7.2 as an example; the tables show a
scheme called Scheme F, developed by the Maine DOT.

Approaches
Approaches are groupings of lanes used in data collection. Using approaches allows you to
collect per vehicle–based statistics that you could not otherwise get, such as the 85th percentile speed for all northbound lanes, and to store these statistics onboard the sensor. Be
aware that adding approaches will increase the size of your data reports, which will aect
the number of these reports your sensor can store in its onboard memory. See the Storage
section of this chapter for more information.
Click the button in the Approaches window to group lanes together in four dierent
approaches (see Figure 7.4).
70 CHAPTER 7 DATA
Figure 7.4 – Approaches
Approaches are used in interval data and will contain the same type of information that
each lane would. An advantage to using approaches rather than post-processing individual
lane data is that approaches gather aggregate data. An example of when this would be useful
is in determining speed limits. Using approaches, the sensor could nd the 85th percentile
speed for all cars in all lanes going one direction, rather than nding it for each lane.
When lanes of diering directions are used, the absolute value of the speed is used to calculate all speed elds. Also, the Right and Wrong direction bins will contain the total number
of vehicles traveling with the user-dened direction of the corresponding lanes in the Right
bin, and all others in the Wrong bin (see the Direction section below).
To create an approach, select the desired lanes and click the button. Each approach can
be named to coincide with the purpose of the approach.
Direction
e direction bins are congured as Right and Wrong. is refers to whether vehicles in a
given lane are traveling in the direction the lane is congured (to change lane direction, use
the lane window in the Conguration screen). is is most useful in the case of reversible
lanes, where trac goes dierent directions in a lane depending on the time of day. In this
case, for part of the day the vehicles would be counted in the Right bin; during the other
part of the day, the vehicles would be counted in the Wrong bin.
To enable direction bins, check the Direction checkbox.
If volume = 0, speed = 0
If during an interval, the volume is zero (meaning no cars were detected), SSMHD will report the average speed of the last interval. If you would like the intervals that are reporting
zero volume to report speeds as zero, simply check the If volume = 0, speed = 0 checkbox.
CHAPTER 7 DATA 71
Note
When NOT using If volume = 0, speed = 0 feature, then if the volume in the interval
is zero, and the occupancy is less than 20%, the speed in the interval will be the speed
of the previous interval. If the volume in the interval is zero, and the occupancy is
more than 20%, the speed in the interval will be zero.
Storage
e Storage window allows you to turn on/o data storage; see a storage timeline, the storage level and the amount of storage space remaining; and clear all storage on the sensor (see
Figure 7.5).
Figure 7.5 – Storage
Use the On/O switch to turn the sensor’s data storage feature on or o. If you check the
Stop when FULL checkbox, the sensor will stop storing data once the storage capacity is
reached, and consequently all new data will not be saved to memory.
e status section shows the date and time that the rst and last interval data packet was
stored and how much storage is remaining by both a status bar and a percentage. e Total
and Remaining elds show how long the sensor has been storing data and how long the sensor will continue to store data before reaching maximum capacity. e capacity is tracked
in months, days, hours, minutes and seconds and is based upon the current sensor conguration. e total number of intervals stored is dependent upon the number of congured
lanes, approaches and bin data types.
If data is stored with a dierent number of lanes, approaches or bin data types from the
current sensor conguration, the Tot a l eld will be incorrect. In this case, the green status
bar is a better indicator of storage capacity. Additionally, using a virtual connection will also
cause the information in this screen to be incorrect.
72 CHAPTER 7 DATA
Note
Some of the settings discussed in this chapter can aect the storage capacity of
your sensor. Changing such data collection settings as the length of the interval for
collecting interval data and the number of bins and approaches configured will aect
how many reports your sensor can store onboard (see Table 7.2 for examples). Always
check back to the Storage screen after you have changed all other settings to get the

To enable data push, select the Event, Interval or Presence tab, then select which method
of communication and format you are using and turn the function on by checking the En-
abled checkbox.
Port
is allows you to select the SmartSensor HD communications port through which the
data will be pushed. If the sensor is pushing data on a half-duplex communication port, the
sensor may not respond to commands due to collisions on the communications bus.
Note
SmartSensor HD's native RS-232 and RS-485 ports are both half duplex.
Format
e following formats are available for all three data types:
HD Format – is outputs the data in the native SS125 format (see the SmartSensor HD
Released Communications Protocols document for information on this format).
SS105 Simple Format – is outputs the data in the SSHD SS105 emulation format
without a multi-drop header (see the SmartSensor HD Released Communications Pro-
tocols document for information on this format).
SS105 Multidrop Format – is outputs the data in the SSHD SS105 emulation format
with a multi-drop header (see the SmartSensor HD Released Communications Protocols
document for information on this format).
For Event Data, there are ve additional format options. All of them output the data in Z4
format. Z4 is a Wavetronix-specic protocol that allows sensors to talk to other Wavetronix
76 CHAPTER 7 DATA
devices, such as Click contact closure devices. e specic formats are as follows:
Z4 2-Loop – With this format, speed and duration are measured using the loop size
and space determined on the Loop Emulation page.
Z4 1-Loop – With this single-loop format, only duration can be determined.
Z4 2-Loop Pulsed – With this format, the outputs will be held active for 125 ms for
each vehicle detected, so only speed will be measured.
Z4 1-Loop Pulsed – is format is simply a presence detector (no speed or duration
information).
Z4 1-Loop Speed – is single-loop format has a set vehicle length of 15 feet, so the
focus is on speed.
For Interval Data, there are two additional formats:
HD (legacy) – is format emulates the interval data from older versions of the Smart-
Sensor HD; it is similar to the current format but lacks speed bins and direction bins
and has fewer length-based classes.
RTMS Format – is format is only available in the Interval Data push conguration
and will output the data in the SSHD RTMS emulation format (see the SmartSensor
HD Released Communications Protocols document for information on this format).
For Presence Data, there is one additional format:
Z4 Presence – is outputs data in the Z4 format.
Destination
is is the address the sensor will push data to and is only valid for HD and Z4 formats.
For HD format, it is the 8-bit subnet / 16-bit ID, and for Z4 format it is a 24-bit address.
Any value up to 255/65535 for SS125 format or 16777215 for Z4 format is valid, but make
sure that this destination address is unique for the communications bus in use. Checking
Broadcast will push the data to the broadcast address (000/65535 for SS125 and 16777215
for Z4). e HD communications protocol reserves subnet/ID 000/00000 for soware applications. e subnet/ID should be set to 000/00000 if the SmartSensor HD is pushing data
to a custom soware application.

Appendix A - 10-pin Connector
Many newer SmartSensor HD installations have a 10-pin connector for attaching the cable;
this connector is used exclusively with the 8-conductor cable. is cable is composed of
eight conductors plus a drain wire, all surrounded by a shield. See Figure A.1 for a diagram
of the 8-conductor cable’s 10-pin socket assignment. e codes listed in the diagram are to
be used to solder wires into the back of the plug where the letters represent the individual
solder cups.

Appendix B - 26-pin Connector
Certain SmartSensor HDs, including the HD legacy, the retrotted HD, and the limited
lane and feature versions, have a 26-pin connector. You can order this connector on two
dierent cables:
e 8-conductor cable, which is the same cable mentioned above; it can be ordered
with either the 10-pin connector or the 26-pin connector.
e 9-conductor cable. is cable is composed of three groups of wires, each contain-
ing color-coded wires and a drain wire surrounded by a shield.
See Figure B.1 for a diagram of the 9-conductor cable’s 26-pin socket assignment. e codes
listed in the diagram are to be used to solder wires into the back of the plug where the letters
represent the individual solder cups.

e 8-conductor cable is nearly identical. e dierences are as follows:
e +485 conductor in the cable (assigned to pin F above) is striped white and blue,
instead of the plain white found in the 9-conductor cable.
ere's no gray ground cable, meaning nothing is assigned to pin K.
Instead of three drains, one for each wire bundle, the 8-conductor cable has a single
drain wire, but that drain wire does not terminate into any of the pins.
Appendix C - Cable Lengths
e following recommendations allow you to provide reliable power to the SmartSensor
HD.
84 APPENDIX SMARTSENSOR HD USER GUIDE
Note
These instructions apply to both the 8-conductor cable and the 9-conductor cable.
e 9-conductor/8-conductor cables’ DC (red and black) wires are a 20 AWG wire pair.
e other wires in the cable are 22 AWG and are used for communication, as detailed in the
earlier appendices.
Cable Gauge 24 Volts 12 Volts
20 AWG 600 ft. (182.9 m) 110 ft. (33.5 m)
Additional 22 AWG Add 400 ft. (121.9 m) Add 75 ft. (22.9 m)
22 AWG 400 ft. (121.9 m) 75 ft. (22.9 m)
Additional 22 AWG Add 400 ft. (121.9 m) Add 75 ft. (22.9 m)
14 AWG 2500 ft. (762 m) 450 ft. (137.2 m)
12 AWG 3900 ft. (1188.7 m) 700 ft. (213.4 m)
10 AWG 6000 ft. (1828.8 m) 1050 ft. (320 m)
8 AWG 9900 ft. (3017.5 m) 1750 ft. (533.4 m)
6 AWG 14,000 ft. (4267.2 m) 2500 ft. (762 m)
Table C.1 – Maximum Cable Length for Power
If the cable length is longer than 600 . (182.9 m) when operating at 24 VDC, it is possible
to increase the maximum cable length by wiring a pair of lines normally used for RS-232
communications with the red and black wires.
In many cases, if the cable length is 200 . (61 m) or greater you cannot reliably use RS-232
communications. To add 400 . (121.9 m) and achieve a maximum cable length of 1000
. (304.8 m), connect the orange wire (normally RTS) to the red wire and the brown wire
(normally CTS) to the black wire.
If your cable run is longer than 1000 . (304.8 m), it is possible to sacrice additional communication pairs to increase the maximum cable length for power. However, you may desire to communicate to the sensor over two independent channels, in which case you will
need to consider an alternate cable for power. e AWG for wire pairs that achieve a 2000
. (609.6 m) maximum cable length or greater at 12 and 24 VDC are listed in Table A.1.
To achieve reliable wired communications, the selected baud rate must be compatible with
the length of the cable run. Table C.2 below shows the cable length recommendations for
wired communications:
APPENDIX SMARTSENSOR HD USER GUIDE 85
Baud Rate (bps) RS-232 RS-485
115200 40 ft. (12.2 m) 300 ft. (91.4 m)
57600 60 ft. (18.3 m) 600 ft. (182.9 m)
38400 100 ft. (30.5 m) 800 ft. (243.8)
19200 140 ft. (42.7 m) 1000 ft. (304.8 m)
9600 200 ft. (61 m) 2000 ft. (609.6 m)
Table C.2 – Maximum Cable Length for Wired Communications
To provide two independent communication channels with a homerun cable length over
200 . (61 m), convert the RS-232 data into RS-485 using a Click 304 in a pole-mount
cabinet mounted next to the sensor. In this case, the homerun connection establishes one
RS-485 channel over the normal white/blue wire pair and another RS-485 channel over the
yellow/violet wire pair. An additional Click 304 is needed to convert the data sent over the
yellow/violet wire pair back to RS-232 before connecting to surge protection.
If you elect to use an alternate cable for power, you may also want to select an alternate cable
for RS-485 communications. For example, the Belden 3105A (Paired – EIA Industrial RS485 PLTC/CM) is a good alternate for the RS-485.
ere are many reliable options available for wiring power and communication connections (see Table C.3).

Appendix D - Direct Serial Connections
For most applications, the service end of the 9-conductor or 8-conductor cable terminates
in a surge protection device. However, during demonstrations, troubleshooting and certain
other situations, it is sometimes convenient to bypass surge protection and connect directly
to a personal computer or communications device such as a modem.
e sensor is congured as an RS-232 DTE device. To connect the 9-conductor or 8-conductor cable’s RS-232 wires directly to another DTE device (such as a PC), you can use a standard
86 APPENDIX SMARTSENSOR HD USER GUIDE
9-pin D connector and a null modem cable. To connect directly to a DCE device (such as a
modem), you will need a straight-through cable. Figure D.1 illustrates both of these cases.

Note
If you do not have the right type of RS-232 physical connection you will not be able
to connect using the SmartSensor Manager software. Since null modem cables and
straight-through cables look similar, you may want to label them. Alternatively, you
may want to use a null modem adapter instead of a null modem cable. If you do,
you can turn your straight-through cable into a null modem cable by attaching the
adapter on one end.
If you wish to connect the 9-conductor cable’s RS-485 wires directly to a PC or modem, this
will require that these devices natively support RS-485 communications. Oen, modern
personal computers do not support RS-485 communications and support USB communications instead. If your computer only supports USB communications, you may want to use
a USB converter to make a direct connection.
Appendix E - Signaling Delays
Signaling delays vary depending on what equipment is used. ese delays may aect decisions about where to install the sensor in relation to other equipment in cases where timeliness in communication is necessary. e following is information about SmartSensor HD
signaling delays.
APPENDIX SMARTSENSOR HD USER GUIDE 87
Total signaling delay from front of vehicle = sensor delay + communications delay + contact
closure delay, where:
Sensor delay = 1 second + (vehicle length in )/(vehicle speed in fps)
Communications delay = ((10/8) * 34 bytes) / (baud rate in bps)
Contact closure delay for Click 512 = essentially zero
Contact closure delay for Click 172/174 = detected duration + (eective virtual loop
length in )/(detected vehicle speed in fps)
