1 OPERATION OF RTMS
The RTMS (Remote Traffic Microwave Sensor) is a true RADAR (RAdio Detection And
Ranging) device, specially designed for traffic sensing applications. It measures the distance to
objects in the path of its microwave beam. The ranging capability allows the RTMS to detect
stationary and moving vehicles in multiple detection zones.
The RTMS microwave beam is approximately 40° high and 15° wide. Its range of 60m (200 feet)
is divided into 32 range-slices, each 2m (7ft.) wide. When pointed onto a roadway, it projects an
oval footprint, in which detection zones can be defined using the range slices.
Range slice
40°
Fig 1.
RTMS microwave beam and its footprint
The RTMS has two mounting configurations and several operating modes.
SIDEFIRED configuration, mounted on a roadside pole, aimed perpendicular to the traffic lanes.
Range-slices corresponding to the location of traffic lanes are defined as detection zones as part of
the setup process. A maximum of 8 detection zones can be defined. Each detection zone may
consist of one or more range slices. Its length is determined by the width of the beam’s footprint.
FORWARD-LOOKING configuration, RTMS is mounted on an overhead structure aimed
parallel to the lane. In this configuration the sensor cannot discriminate between lanes and the
aiming angle must be carefully adjusted to confine the footprint to a single lane.

Vehicle Detection
Use of long-wave microwave and ranging, enables accuracy in severe weather, strong vibrations
and detection of vehicles completely occluded by other vehicles. Mounting can be relatively low.
The RTMS receives reflected signals from all surfaces within its beam - pavement, barriers,
vehicles and trees. It maintains a background signal level from fixed objects in each range slice.
Vehicles are detected when their reflected signal exceeds the background level in their range slice
by a certain threshold level. If that range slice is part of a defined detection zone, its contact is
closed during the detection time to indicate detection and internal counters are incremented.
The background level “capture” requires 30 seconds to fully settle during setup. It is continually
adjusted during normal operation. As an example, signals from a stalled vehicle will be
incorporated into the background after about 30 minutes and detection will cease (zone contact
will open). However, when the vehicle is removed, the background level falls rapidly to the
original level, resuming detection at full sensitivity within seconds.

Each vertical bar represents a separate range slice
Fig 3.
Reflected signals within the RTMS beam
The strongest signals are reflected from vertical surfaces of vehicles. Horizontal surfaces (e.g.
roofs) tend to scatter the microwaves away from the sensor, reflecting weaker signal.
Signal levels from vehicles vary depending on the shape of the vehicle and can dip below the
detection threshold during brief intervals called nulls. To prevent multiple counting due to nulls,
the RTMS signal processing includes an Extension Delay Time (EDT) to bridge the nulls and
hold the presence indication. The RTMS system corrects for the effects of EDT to obtain the
correct Occupancy measurement. RTMS X3/K3 Rev 6.1 and up can emulate a 6 ft loop.
The Threshold level and EDT are two of several parameters, set to default values when the Mode
of Operation is selected. These parameters optimize the operation for the selected application.
Outputs
The detection of a vehicle in any zone is registered in two independently operating outputs:
• Zone Contacts: 8 contact pairs corresponding to the detection zones are closed for as long as
detection persists. They can be connected to Traffic Controllers to indicate presence (in
intersection applications) or to Counters for traffic measurement. An external Interface Card can
add Fail-Safe operation, EDT correction and Dual-loop speed trap emulation.
• Data Port: Detection status in each range slice is transmitted via “target” messages sent 10
times per second. RTMS internal firmware uses vehicle detection to accumulate Volume,
Occupancy, Average Speed and Classification by length over a user-defined Period. At the end of
the period the accumulated data, containing measurements for all zones, is transmitted.
• Data Port Options: Besides RS-232, RS-485 and TCP/IP Ethernet interface options, Model
X3/K3 units support an optional internal DSS wireless modem, which can transmit either statistic
measurements or contact closure information directly from the unit.

Align the holes in the bracket with the RTMS mounting-pin holes and insert the lynch pin.
Do not use undue force or tools. When fully inserted, flip its ring to snap into place around the
ball-joint
Using a 7/16” wrench, loosen the bracket bolt to release the ball-joint and aim the RTMS per
the Mounting and Aiming section. Tighten the locking bolt firmly. Once properly aimed,
RTMS can be quickly replaced without need to repeat the aiming process.
Mate the cable’s MS Connector (see Section 5 for Cabling instructions) to the RTMS with the
wide connector key pointing to the front of the sensor. Twist the MS Connector outer ring
clockwise half a turn until it locks with a click. If an internal DSS modem is included, screw
on the supplied antenna.
Connect the RTMS cable data port connector to a laptop PC and perform Setup per
instructions in Section 3. During setup, aiming corrections may be required.
Recording details of the RTMS setup and location is recommended. See Appendix 2 for
completed samples of forms, which can be made available.

RTMS Mounting and Aiming
The mounting site selection should take into consideration the set-back and height requirements.
For best results, mount the sensor at the correct height and aim it initially as shown below.
Sidefired Configuration
Set-back and Mounting Height
To include all lanes of interest within its beam footprint, the RTMS must be set back from the
detection zones.
For set-backs less than 20 feet (6m) RTMS should be mounted at 17 foot (5m) height above the
road surface. Minimum set-backs for monitoring the required number of equivalent lanes are as
shown by Fig. 5.
Equivalent lanes include median strips, e.g. an eight lane road with a two lane wide median strip
has 10 equivalent lanes. The span of 13 equivalent lanes plus the required minimum 25 foot
set-back approaches the range limit of the RTMS.
If the set-back is more than 20 ft, the height may be increased approximately 3 feet per 5 foot
increase in set-back to a maximum of 30 feet, as shown by the graph. The 30 foot set-back and
23 foot height represents an ideal location for any highway application.

Initial Aiming Instruction
The following guidelines are recommended for good coverage of all lanes to be monitored.
• Look from behind the unit and use the top and sides as a guide to “eyeball” its boresight
direction:
•
Adjust the sideways sway of the RTMS to be perpendicular to the travel lanes.
•
Tilt down so that the top of the RTMS is aimed to the first 1/3 of the monitored lanes.
•
Keep the RTMS level, side to side.
Note: Final verification of aiming is performed during the setup procedure (See Section 3)

Aiming to the first 1/3 of the monitored lanes
Pointing RTMS away from heavy structures
When deploying RTMS on heavy structures such as overpasses and some sign-bridges, mount
them so that the microwave beam clears the structures to avoid multi-path distortion of the beam:
•
Do not mount directly on perpendicular
(or preferably angled) overpasses. Use
separate poles at least 7m (20 feet) away.
•
When having to mount on angled
overpasses, take advantage of the angle,
as shown and use 5 ft extension arms.
•
Mount sensors on the “clean” side of
heavy-structured sign bridges, away
from catwalks and lighting at a small
angle as shown (not exceeding 15°).
Extension arms are also recommended.

Mounting RTMS at intersections
•
Poles at optimal locations allow aiming at the stop bar while perpendicular to the traffic lanes
•
Mounting across the road from the detection zones widens the footprint by increasing the setback, makes the beam more perpendicular and ensures no occlusion of Left-turn lane.
When existing poles are not in optimal position, use of extension arms is recommended to
alleviate outlined problems and improve performance
• Mounting of sensors on poles close to the detection zones, narrows the footprint due to limited
set-back and increases occlusion in the Left-turn lane.
•
The larger offset angle (over 15° from perpendicular) scatters the microwave beam and causes
detection misalignment into unwanted areas.
•
It reduces the reflected signal, and therefore, the performance.

Issue 3.2
Forward-looking configuration
In highway traffic monitoring applications, sensors are mounted on a sign-bridge or overpass
away from interfering structures, as shown below. The sensor can be aimed at approaching or
receding traffic, but aiming at receding traffic is preferable.
• Mount the sensor above the center of the lane at the recommended height of 5m (17 feet) but
not exceeding 6m (20 feet).
•
Point it parallel to the monitored lane
•
Mount it level side to side
Looking from behind the unit, “eyeball” - aim it to a point about 10m (30 – 35 feet) from the
sensor. This will ensure a sufficiently long footprint but restrict its width to a single lane.
20 ft max.

Incorrect aiming will result in poor accuracy. Aiming adjustments may be needed during setup,
where verification is performed using a PC.
Sensor not level – footprint is skewed
Sensor aiming not parallel to lane – footprint
extends into neighboring lane
Sensor mounted too high or aimed too far –
footprint is wider than one lane

4 SETUP OF THE RTMS
The PC requirements
Installed RTMS sensors are calibrated using a laptop PC operating under MS Windows. The
operator connects the PC to the RTMS Serial port and runs the interactive RTMS Setup Utility
“WinRtms” program while viewing the monitored road traffic. Therefore, cabling arrangements
must provide access to that port within view of the monitored lanes.
A PC equipped with a USB port only, requires a converter to RS-232. Care must be taken that the
converter driver is correct for the Operating System employed, e.g. driver for Windows 2000 may
not work with Windows XP.
The RTMS Setup Utility (WinRtms)
Installation
RTMS Setup Utility program is provided on a CD. Insert CD into your CD-ROM. If “Autorun” is
enabled, the content of the CD will be shown. For Windows 98/2000/NT4/2000/Me system, open
the ‘Software’ folder, double click ‘WinRTMSInst.exe” icon and follow installation instructions.
The WinRtms install utility will install the WinRtms program and two files in the RTMS folder.
Rtms.ini configuration file retains the main program settings (e.g. speed, mode of operation, etc).
The Rtmslng.txt file contains all screen legends and can be edited to accommodate other
languages. See Section 5 - Non-setup Functions of the Setup Utility for further details
Direct and Multi-drop Communication Modes
The WinRtms program communicates in Direct and Multi-drop modes.
• Direct mode is employed for individual RTMS setup, outlined in this section.
• Multi-drop mode allows communication with several RTMS sensors connected to a common
communication line, e.g. for the purpose of data collection. See Section 5 - Non-setup
Functions of the Setup Utility to configure WinRtms program for this function
• An RTMS equipped with TCP/IP interface (identified by a label on the bottom of the
enclosure), may be accessed via the Internet. Winrtms must be set to communicate using an
IP address rather than the Serial Port. See Section 5 - Non-setup Functions of the Setup
Utility to configure WinRtms program for this function
For direct access, the RTMS must be unplugged from the hub and connected to the PC
network card. PC networking setup must be changed to static IP address. See Appendix 2 on
PC setup and setting of the RTMS IP address.
The WinRtms program is designed for use outdoors, where screen visibility is reduced by the sun
glare. While supporting “point and click” mouse functionality, most functions may be performed
using the UP/DOWN, LEFT/RIGHT arrow keys, the ENTER key and keyboard shortcuts
(keying underlined letters). Setup actions are identified by ⇒
RTMS equipped with higher revisions of firmware, may require latest versions of WinRtms.
WinRtms Ver. 3.0 and up features automated or assisted setup through its Wizard.

Getting Started
With the RTMS sensor connected to the PC as appropriate to the data interface, click the
WinRtms.exe icon to launch the RTMS Setup Utility program.
The RTMS Setup program, initially set to its Direct
mode, attempts to establish communication with the
RTMS and displays the message on the right, while
attempting to read the current RTMS setup.
If WinRtms is set to its Multi-drop mode, it will display a window presenting a polling range of
first and last Sensor IDs. See Section 5, Non-Setup Functions of the Setup Utility on changing
the mode of communication to Direct.
If WinRtms in Direct Mode is unable to read the RTMS setup, it will display the messages below
suggesting a course of action to recover. Possible reasons for failure to read may be:
• RTMS is not connected to the PC or is not powered
• PC RS-232 Serial port is not working or is not free
(e.g. used by another application) or wrong cable is
used to connect other data interfaces
• RTMS is set to Polled mode

in multiple zones. Used in Stop-bar detection
Intersection
Default settings:
Mid. Intersection
Forward Look Hwy
EDT = 1000 msec, Threshold =Low.
Similar to Sidefired Highway mode, this mode is for use in midblock detection in urban settings.
Default settings:
EDT= 1000 msec for up to Rev 5.5,
300 msec for Rev 6.1 and up
Threshold = Medium.
Used in applications demanding high accuracy of speed
measurements such as Speed Enforcement. Zones 1, 2 and 3 are set

Zone Setup – Sidefired Modes
Vehicle target “blips” are displayed along the range scale in real time. The objective of zone setup
is to use these blips to identify the correct range slices as detection zones. Only detection of
vehicles inside the configured zones will close contacts (zone numbers correspond to contact
numbers) and generate traffic data. Targets blips outside of configured zones are ignored.
Automatic Zone Setup
The AUTO button (RTMS X3/K3 Rev. 6.1 and up only) initiates automatic setup of detection
zones to all detected traffic lanes (up to 8). The automated process requires sufficient traffic levels
and is aborted if it is too low to determine position of lanes.
⇒ Select ZONES button. The NUMBER OF ZONES window will be
displayed.
⇒ Click AUTO for automated zone setup (number and position of
zones). This will be done with a fine tune of zero only.
When the process is completed, Zone numbers will be in ascending
order as the distance increases. Make zone and fine tune changes
using the Manual procedure.
Manual Zone Setup – Side-fired Mode
⇒ Use the UP/DOWN keys (or click the arrows) to change the number
of zones. In a side-fired mode, the number of zones is set to the
number of lanes to be monitored by the RTMS.
⇒ Press ENTER, click OK or type O to progress to the next stage,
zone positioning and sizing.
⇒ Select any zone by typing its number, e.g. type “1” to select Zone 1.
The zone icon starts flashing and can be moved. The setup utility
allows full flexibility in assigning a number to the detection zone,
e.g. Zone #1 may correspond to the lane closest to the sensor or
farthest away from the sensor. Zone numbers do not have to be in sequence.
⇒ Glance at the screen when vehicles cross the RTMS beam in the lane intended as the detection
zone. Use LEFT/RIGHT arrows (in the ZONES SETUP window or on keyboard) to move
the zone icon to its desired position along the range scale, to surround the vehicle blips.
Repeat the process for each of the lanes to be monitored.
Press the Space-bar to toggle a “presence indication” beep, which sounds when a blip is
detected in the selected zone. The beep allows detection confirmation in a zone without
looking at the screen.
In most cases, each lane requires a single range-slice zone. Multiple range-slice zones can be
employed in intersection applications, e.g. to combine through-lanes into a single detection zone.
A contact corresponding to the zone number is closed as long as presence is detected in any lane
inside the zone.

If two blips show simultaneously in a wide zone, they will be counted as one. Thus in highway
and counting applications multiple slice zones are useful in rare cases where it is necessary to
cover a wide lane.
⇒ Use UP/DOWN keys (or click SIZE arrows) to increase or decrease the size of the zone (to
multiple range slices).
⇒ After all zones are positioned, Press ENTER, click OK or type O to close the window.

Fine Tune
“Splashing” is defined as a single vehicle (mainly trucks) causing two blips in adjacent detection
zones. A vehicle straddling two lanes or the detection zone straddling two lanes may be the cause.
It results in over-counting and is undesirable.
Fine Tuning minimizes splashing, by making small adjustments to the size of all range slices
(about 2% of the range per step for a maximum of ±10%). Farther range slices are affected more
than closer ones. When the Fine Tune setting is changed to correct a splash, some vehicle blips
may shift out of the defined zones. It may be necessary to re-enter ZONE SETUP to redefine
zone positions, particularly further zones. Fine Tune is also used to reduce the effects of barriers
on detection in nearby lanes. Adjust Fine Tune to confine barrier signals to a single range slice.
Note: The effect of Fine Tune is only shown on the screen by the behavior of vehicle blips.

Typically, a “splash” into a lower range slice (closer to the sensor), is corrected by increasing the
Fine Tune number (blips are pushed up-range – into the correct slice). Conversely, a “splash” into
a higher range slice can be pulled down, by reducing the Fine Tune number.
The diagram below illustrates how Fine Tune setting affects the position of range slices and
detection zones. In this example, at FT=0 the range-slices straddle two lanes and produce
splashing. Both FT= +5 and FT= -4 yield acceptable results.

Fig 14. The effect of Fine Tune Control on vehicle blips
When dealing with a few detection zones, it is easier to find a correct fine tune setting to satisfy
all traffic lanes. Attempting to monitor many lanes with a single sensor may require a
compromise on the counting accuracy in some lanes due to splashing.
Whenever Fine Tune changes are made, the RTMS “captures” the new background and requires
about 30 seconds to “settle”.

Fine Tune Setup
Automated or manual setup procedure can be selected
⇒ If the first and last zones are well defined, you can click AUTO
(RTMS X3/K3 Rev. 6.1 and up ) to initiate automatic Fine Tune
(Zone setup included). When the process is completed, further
changes can be made using manual procedure.
⇒ For manual Fine tune setup start with setting of “0”. Observe the
incidence of splashes and determine whether the Fine Tune number
should be increased or decreased. Use the arrows in the window or the
Up/Down keyboard keys. To ensure the best Fine Tune value was
found and protect the performance against small drifts,find the Fine
Tune “sweet spot” by modifying FT +/-1 and visually verify that the changes have very little
effect.
⇒ Click OK when satisfied with the setting to save it in the RTMS
Zone Setup – Forward-looking Mode
Use of Wizard for Forward-Looking mode zone setup.
Initiate the automated zone setup either by clicking the Wizard icon or AUTO button on the
Zone Setup window.
⇒ Enter the Height and Offset parameters when prompted.
⇒ The Wizard will determine, based upon traffic, the best location for the 3-zone speed-trap. If
it cannot find a good speed trap due to incorrect RTMS aiming, low volume or other causes, it
will display Warnings.
Manual Zone Setup – Forward-looking Mode
⇒ Set Number of Zones to 8 and position all zones in sequence with the first zone at
approximately at 8m (8 yards) from the sensor (farther if the sensor is higher than 5M)
Observe approaching (or receding) vehicles in the lane as "waves" of blips and adjust the tilt
and sway angles so that blip waves from small vehicles go through at least 5 of the 8 zones
and so that vehicles in adjacent lanes do not show blips in the zones. Detection of vehicles
from an adjacent lane indicates that the sensor is angled in that direction.
⇒ Fine Tune control affects the size of the zones and may be used to improve smooth passage
through all three detection zones. Set it to +5.
⇒ Perform count vefication over 50 vehicles or more. Find three consecutive zones, with vehicle
counts in close agreement with each other and with the manual count.
The location of these three zones will form the speed-trap. Note their position on the range
scale and using ZONES, move zones No. 1, 2 and 3 over these three consecutive zone
positions (ie. zones 5, 6 and 7), then reduce the number of zones to 3.
Only Zone #1 is used for Volume and Occupancy data. Zone #2 and #3 complete the speed trap
and help monitor the direction of travel.
The per vehicle speed measurement (it has a distinctive beep), is made only if the vehicle is
detected in all three zones. It is displayed if the Per Vehicle Speed box is check-marked.

Count Verification
To verify the setup correctness, one must compare RTMS detection to the presence of vehicles in
each lane. In Intersection mode applications, this is done visually over a period of time.
In highway modes (Sidefired or Forward-Looking) the Count Verification procedure compares
RTMS volumes in each detection zone to manual counts performed over the exact same interval.
Use of a hand-held tally counter for manual counting is recommended.
Perform the following steps:
⇒ Select PERIOD and set the Message Period to 30 seconds
⇒ Select VERIFY button
⇒ When the left-side window opens, tap the Space bar to checkmark the box in the CLEAR
TOTAL COUNTERS ON NEXT MESSAGE ARRIVAL field and get ready to start
counting.
⇒ At the end of the current Message Period the window background blinks, the PC beeps and
the RTMS count line is cleared, signaling the precise time to start the manual count.
⇒ Start counting vehicles in the selected lane as they cross the RTMS beam. Several people may
be involved, each counting traffic in an assigned lane.
⇒ At the end of each Message Period, signaled by a background blink and a beep, the RTMS
count in each zone is incremented by this period’s volume
⇒ Keep counting through several periods, until reaching at least 50 vehicles in that lane, then
stop counting precisely at the end of the Period.
⇒ Tap the space bar to checkmark the STOP COUNTING box, freezing the RTMS Count.
⇒ Enter the manual-count data in the corresponding detection zone boxes.
⇒ The PC displays the difference between the RTMS and the manual count reference in absolute
and % deviation. Deviation in beyond approx. +/-5% may require setup correction (e.g. zones,
Fine Tune or Sensitivity) to improve accuracy. The verification process should then be
repeated.
⇒ Successive Space bar tap recycles to the left hand window to repeat the process, if necessary.
⇒ In Forward-Looking modes, only Zone 1 (representing the RTMS count) needs verification.
⇒ Select SAVE to save the results of verification in a text file.
⇒ Select OK to exit to the main screen

Speed Calibration
This process adjusts internal coefficients used by the sensor to calculate the average speed of
traffic in each lane. It can be accomplished in two ways:
•
Automatic Speed Calibration is intended for high-volume traffic, flowing at stable speed. It
requires entering per-lane reference speeds, which may be estimated or measured (e.g. by a
police radar) and setting the procedure duration as a number of Message Period cycles. 5
minutes (10 cycles of 30 seconds) is recommended.
•
Manual Speed Calibration is intended for low-volume traffic (e.g. volume less than 5) or
when there are a high number of trucks. Here the coefficients are directly changed to bring the
calculated speed closer to the reference (estimated) speed.
Sidefired Speed Calibration
In Sidefired Highway mode, the RTMS uses the dwell-time of vehicles in their detection zones
for speed calculation. The zone’s “speed coefficient” is proportional to the zone length plus the
average car length.
Vehicles with dwell-time exceeding twice that of an average car are excluded from speed
averaging calculations. Good speed calibration is necessary for accurate average speed calculation
and truck classification.
Sidefired Automatic Speed Calibration
⇒ Select the SPEED CALIB. button to open the
window to define a Speed Reference for each
configured detection zone.
⇒ Use the LEFT/RIGHT keys to highlight the zone
references,calibration cycles or the Quit button.
⇒ Use UP/DOWN keys (or keyboard entry) to set
the desired reference speed in the highlighted
zone box lane. Reference speed is your estimate
of the current average speed in this lane. Type an
“X” to exclude that lane.
⇒ Select Number of calibration cycles and use UP
key to increase it in multiples of 5.
CALIBRATION IN PROGRESS will flash.
⇒ At the end of each Message Period, the Setup Utility adjusts the values of all active zone
coefficients to converge to the reference speeds. The number of cycles is counted down.
⇒ To block further changes in a zone coefficient, highlight the zone and type “X”.
⇒ When all speed measurements are reasonable or if traffic flow changes during calibration,
terminate the Calibration by clearing the number of calibration cycles to OFF (use DOWN
key). Continue when traffic flow resumes.
⇒ Select Quit (click or highlight and press ENTER). This will terminate speed calibration.

Calibration window will show the current
coefficients for each zone.
⇒ Compare the displayed speed measurement to
your estimated average speed in each lane.
⇒ Use LEFT/RIGHT keys to select zone and
UP/DOWN keys to adjust coefficients (in 150 to 640 range) proportionately to the required
change (e.g. if speed readings are 10% too low, increase that lane coefficient value by 10%).
⇒ Select Load speed coeffs or press L and key ENTER to update all RTMS coefficients.
⇒ Observe the effect on average speed measurements displayed on the screen at the end of the

⇒ Click Quit to exit
Forward-Looking Speed calibration
Per Vehicle Speed
Per vehicle speed measurements is required for Forward-Looking mode speed calibration. Ensure
that the main screen box Per Vehicle Speed is check-marked while performing forward-looking
speed calibration. Click this box to suppress transmission of per vehicle data, if desired, after
completion of speed calibration.
The Forward-Looking Highway mode uses the averaged, per vehicle Doppler speed, as the
reference speed to calibrate the length of the speed trap to assure accuracy of “trap” speed
measurements at low speeds (below 15 Km/h).
Automatic speed calibration is included in the Wizard automated zone setup for the ForwardLooking mode. It may also be independently initiated.
When SPEED CALIB is selected, a choice of
Automatic or Manual calibration is presented:
⇒ Select the required mode of calibration
In Automatic calibration, the recommended number of
cycles is 10 (at 30 sec. Period). The Doppler reference
speed and % deviation of the average speed from the
reference are updated at the end of each Message
Period. When deviation is less than 10%, exit the
program.
In Manual calibration the zone length coefficient must
be adjusted up or down (range 150 to 500)
⇒ Click LOAD and wait to get acceptable deviation
from the Reference speed .

5 NON-SETUP FUNCTIONS OF THE RTMS SETUP UTILITY
Setting the RTMS Setup Utility Communication Mode
Note: The RTMS Setup Utility starts in the last mode selected. To
change mode, an RTMS need not be connected. Do the following
⇒ Respond with NO to any messages presented on start-up
⇒ Open TOOLS window (highlight button and key Enter)
⇒ Select Direct mode when PC is connected to a single RTMS
⇒ Select Multi Drop mode to communicate with several sensors.
See Section on Communicating with Multiple RTMS units on
the next page.
Setting the PC Communication
⇒ Select PC COMM from the TOOLS window
COMMUNICATION PROTOCOL SETUP window
opens.
The default RS-232 setting applies if the RTMS is equipped
with RS-232 or RS-485 interface (identified by a label on
the underside of the sensor).
If RTMS is equipped with Ethernet interface as identified by
RJ45 connector and label on the underside of the sensor, see TCP/IP below
Serial Port only
⇒ Ensure correct COM port is selected
To communicate, the PC and RTMS serial ports must be set to the same speed. RTMS models
up to X2/K2 support only 9600 bits/sec. Model X3/K3 supports additional speeds up to
115200 bps. The RTMS Setup Utility attempts to adjust the PC COM speed to that of the
RTMS unless disabled by clicking the DISABLE AUTOBAUDRATE box.
Speeds lower than 9600 are useful where high quality transmission lines are not available.
They are, however, unsuitable for setup and must be set after completion of setup. If lower
speeds must be used, the RTMS data mode must be set to STAT to reduce the amount of data
and prevent communication problems.
⇒ Select the desired speed, suitable for the application from the drop-down menu and click the
SEND IT TO RTMS button to change both PC port and RTMS port speeds.
⇒ If the RTMS Model X3/K3 is equipped with the DSS modem a DSS MODEM SETUP
button will be on the window. Click it to display the setup window, shown in next section.
The DSS modem option forces the RTMS serial port to a speed of 115200 bps .
TCP/IP only
⇒ Click box if the RTMS is equipped with an Ethernet interface Set the displayed fields
(protocol (TCP or UDP), Local and Remote Port and Remote Host network address). Consult
Appendix 2 for instructions on re-programming the default IP address of the RTMS.
⇒ Click OK to save settings as displayed and to close the window.

Setup of Integral Digital Spread Spectrum Modem
A green rectangle displayed next to the data activity flashing “lamp” in the screen’s lower right
corner indicates that the RTMS is equipped with a DSS modem and that the modem is
communicating (synchronized) to a master. If the rectangle is red, there is no synchronization.
Internal DSS modems are setup at the factory according to the requirements of the installation and
should not require further setup. If changes are required refer to Appendix 3.
Communicating with multiple RTMS units in Multi-Drop Mode
The RTMS Setup Utility, when set into the Multi-drop mode, communicates with several RTMS
units connected to the COM port. The sensors will be in Polled Data mode. (Not applicable to
sensors with Ethernet (TCP/IP) interface).
The RTMS Setup Utility Multi-drop mode, selected via
the TOOLS menu (see Setting the RTMS Setup Utility
Communication Mode), will present the POLLED
SENSORS window shown:
⇒ Edit the required ID range limits of the com. line.
⇒ Select OK to activate
On restart, the RTMS setup Utility will present the POLLED SENSORS window with last
entered range of sensor IDs for acceptance or changes and force all RTMS units on the
communication link into the Polled mode.
Next it will generate sequential polling commands for all IDs in that range. The received data is
displayed in the Traffic Statistics area and the polled sensor ID in the lower left corner of the
screen. The received data can be stored as indicated in Data Recording.
Accessing a specific sensor in Multi-Drop Mode
To access a specific sensor, it is necessary to disable polling and change its data mode to Normal:
⇒ Confirm that RTMS Setup Utility is polling (Polled
Sensor IDs are displayed at the lower left corner)
⇒ Select the DATA button on the main screen and select the
NORMAL mode.
⇒ Specify the SENSOR ID Number in the presented
window using UP/DOWN keys only
⇒ Select OK (click it or use LEFT/RIGHT keys to
highlight followed by Enter)
The specified sensor’s Data mode is changed to Normal and polling of other sensors stops. The
RTMS Setup Utility communicates with that unit, automatically reading its setup and displaying
its parameters, blips and statistical data. Setup can be changed, as required.
EIS Electronic Integrated Systems Inc.
RTMS User Manual
Issue 3.2
31
⇒ To select another sensor for access, repeat the above steps. Only one sensor is allowed to be in
Normal mode to avoid message collisions. The previous sensor is forced into Polled.
⇒ To resume polling, change the last sensor’s data mode to Polled or exit the RTMS Setup
Utility. It will automatically open in Multi-drop mode and display the POLLED SENSORS
window.
⇒ To change the Setup Utility communications mode from Multi-drop, select TOOLS, then
Direct. The utility will now assume that the PC is connected to a single sensor in Normal
Data mode and will attempt to read its setup.

6 CABLES
The RTMS cable
RTMS uses a single 32-pin MS connector for power and all outputs.
The RTMS is shipped with all required connectors, crimp pins and back-shells. Cables may
require on site preparation if their length is unknown or to pass them through conduits. The
installer must assemble the connector back-shell, crimp pins to cable wires and insert them into
the connector shells.
The RTMS cable should be UV protected where exposed. It should be overall shielded and
furnish sufficient number of stranded gauge #20 or #22 twisted pairs (e.g. Belden 95xx) to
provide the following:
Description

Power Cabling notes
•
Standard low voltage 12-24V AC or DC
Low voltage power can be derived from:
• Controller cabinet 24VDC, if available
• Transformer in Controller or pole-mounted cabinet, 16-20V AC 10W recommended
• 12V Battery - Recharged by a solar panel or from lighting supply
The range of standard low voltage RTMS power at the input is 10.5V to 34V. Voltage outside this
range will cause the sensor to shut down. Cable resistance must not reduce available voltage
below the lower limit.
Peak voltage at 24VAC is approximately 34V i.e. at upper cutoff. The use of 24V AC should be
avoided where cable runs are short.
Model X3/K3 includes internal cutoff switch at 11.5 V to prevent battery damage due to deep
discharge.

RTMS Serial Communications and Cabling
Standards and Nomenclature
Data communication equipment is classified as Data Terminal Equipment (DTE), which
generates and stores data (e.g. PC) or Data Communication Equipment (DCE), e.g. modems.
RS-232 Serial ports use two types of RS-232 connectors, the 25-pin DB25 and the 9-pin DB9.
DTEs employ male connectors and DCEs employ female connectors. 8 essential functions and
their corresponding pin assignments are shown below.

Note that while a DTE transmits on Tx and receives on Rx, a DCE does the reverse, i.e. receives
on Tx and transmits on Rx. Control signals may be ON (Positive Voltage level in 5-15V range)
or OFF (negative voltage level in 5-15V range). To transmit, RTS, CTS, DSR, and DTR are
required to be in the ON state, where implemented (Note: not all signals are implemented by
DTEs and DCEs).

RTMS Serial Port Wiring
RTMS Models X2/K2 have an isolated RS-232 port with a range up to 250m (800 feet) at a speed
of 9600 bits/sec. Modems are required if this range is exceeded.
RTMS models X3/K3 have a variable speed Serial port with speeds up to 115.2 kbits/sec selected
by the user during the setup. The serial port can also be configured as RS-485 (optional) for an
extended range up to 4000 ft. with multi-drop capabilities without the use of modems.
RS-232 Port wiring
The RTMS cable wiring is configured to provide a null modem function for direct connection of
the sensor to a PC for setup purposes using a standard extension cable.
To do this the RS-232 port is wired as a DCE, i.e. transposes transmit and receive lines and uses
a female 9-pin connector.

⇒ Connect MS connector pin “a” to DB9F pin 4 (DTR).
During normal operation the RS-232 port feeds the DSS modem. On direct connection to a PC,
RTMS detects the positive voltage on pin “a” from the COM Port (DTR ON) and switches its RS232 Rx line to the PC. Upon disconnecting from the PC COM port, the RTMS will re-connect it
back to the DSS modem.
Without the above modification, the receive line will be connected to DSS, the RTMS Setup
Utility will be unable to send any commands to the RTMS and setup will not be possible.

Modem cabling
Modems may be wireless (CDPD, CDMA, Spread Spectrum) or wire-line (fiber or telephone
line). Most wireless modems use 9 pin connectors. Most line modems use 25 pin connectors.
Their connectors are female.
A cable connecting the RTMS Serial port to a modem must employ male connectors at both ends
and must transpose the Rx and Tx lines.
Since the RTMS serial port does not include any control lines, some modems may also require
looping of their own control lines (RTS, CTS, DTR, DSR) to always receive data.
The modem cable instructions below, show maximum requirements designed to meet the needs of
all modems. Connect pins of the male connectors as shown by the table and diagram below:

Accuracy Performance Conditions!
Error performance parameters outlined above are achieved under normal, high-flow traffic
conditions and are subject to proper installation and setup. Reduced accuracy (higher errors) will
be experienced under the following conditions:
• Low speed, high congestion conditions: The RTMS tends to over-count under low speed
conditions (below 1mph) as the setting of the EDT parameter may not bridge nulls in the
reflected signals adequately resulting in multiple counts.
• Low vehicle volumes in Sidefired configuration (as experienced during night time) may
result in higher speed data fluctuations due to the small statistical sample.
• Improper selection of installation site: insufficient set-back, height beyond the
recommendation, obstruction by barriers or high fences before monitored lanes.
• Improper Fine Tune setting for the road geometry (lane width, barriers, etc.) will result in
“splashing” and, therefore, over-counting. In some cases, attempts to cover too many
traffic lanes with a single RTMS may result in inability to find correct Fine Tune setting
and compromised performance.
• In Forward-Looking Hwy configuration, high variance between the volumes in the speedtrap zones due to improper aiming or obstructions within the trap range or incorrect
Height or Offset parameters may result in higher speed and length measurement errors.

9 RTMS TROUBLESHOOTING GUIDE
Field troubleshooting of the RTMS consists mostly of ensuring that the unit is powered and
communicating and running the Self-Test (two-way communication is required to run Self-Test).
Communication from a sensor in Normal mode is indicated by flickering of the “lamp” in the
lower right corner of the screen, denoting target data transmission activity.
The Self-Test is invoked using the RTMS Setup Utility by selecting TOOLS and Self-Test. The
test checks internal functions and locates hardware faults. The "All tests complete System OK!"
message is displayed on the screen if no faults are found. The following is a list of Self-Test
messages describing a fault and corrective action.
"Power supply fault!"
Send back
"Modulator signal fault!"
Send back
"Microwave module fault!"
Call EIS
"Temperature calibrator fault!"
Send back
"Modulator memory fault!"
Send back
"Program memory fault!"
Send back
"DSP fault!"
Send back
"Gain too low or ADC fault!"
Call EIS
"Logic failure"
Call EIS
"No signal"
Call EIS
"Saturation signal level"
Call EIS
The Self-Test cannot test the Opto-pairs. It will, however, close the zone contacts for one second
in sequence. Operation of opto-isolated contacts can then be verified using the controller display,
ohm-meter or any other suitable device showing continuity.
The table below outlines symptoms and suggested action in troubleshooting power and
communication problems:

Check that the supply voltage is within limits at
source and at the MS connector as defined in
Section 6. Voltage outside the limits (too low or
too high) will cause power supply shut down.
With power applied to the RTMS and DB9F
disconnected from PC, check the RTMS serial
Port by measuring approx –10V between pins 2
and 5 of the DB9F RS-232 connector. If the
voltage is not present there could be a hardware
fault in the RTMS serial port or power supply. If
neg voltage is there.
Check cable pin-out and continuity particularly
between MS connector pin T and COM port’s
pin 3 (Tx line)

WIRING CONFIGURATIONS FOR MULTIPLE RTMS
Modem Sharing
A limited number of RTMS units in polled mode, located within a short distance, may share a
single modem. While models X2/K2 require use of contact #9 (see RTMS Cable modification
below) , models X3/K3 Serial port design allows two or more transmit lines to be connected
directly without interference.
A cable for modem sharing will have Y-cable construction and will consist of one DB-9M
connector per RTMS and one DB-9M or DB-25M connector at the modem, as shown below:

RTMS Model X2 Cable Modification
The design of the RTMS Serial port of the Model X2/K2 requires that only one transmit line is
connected to the modem at a time. This is achieved by using the Opto-isolator contact #9. The
RTMS closes this contact on receipt of its ID number in the polling message. The RTMS cable
must be modified to insert this contact in the transmit path, as outlined below:
⇒ Ensure pins d and e are present in the MS connector of each RTMS
⇒ Loop the RTMS transmit line (pin V) to pin “e” inside the MS connector back-shell
⇒ Connect pin “d” to pin 2 of RTMS DB9F connector. Note: pins “d” and “e” are
interchangeable. Looping pin V to pin “d” and cabling pin “e” to DB9 pin 2 is also correct

Multi-drop Wiring
Multiple RTMS stations operating in Polled mode may be connected to a single communication
line or channel for transmission of data. Each must have its own modem when separated by more
than the limits of the serial port. Each RTMS receives the poll commands but transmits data only
on receipt of its own ID. See RTMS RS-232 port to Modem cables per Fig. 24

RS-485 Port Multi-drop Wiring
Notes:
1. The use of DB9F connectors, as shown, allows direct connection to the laptops COM port for
setup. Wiring must allow for unplugging the RTMS from the transmission line. Use of
terminal blocks to connect the DB9M connectors to the transmission line is recommended.
2. Terminating resistors (100-120 ohms) are required at the extreme ends of the Receive and
Transmit transmission pairs.
3. Transmit and receive pairs must be transposed when connecting to a RS-485/232 converter
for direct interface with a DTE (Data processing System).
4. RS-485/232 converter pin assignment varies between models as it is not standardized.

SETTING RTMS IP ADDRESS
Programming an IP address
The RTMS Micro-Server is programmed with a default IP address 128.100.101.254. This address
may be changed using a directly connected PC, as follows (note slight differences between
versions of Windows):
⇒ Set PC network address in the range 128.100.x.x in the following steps
•
•
Access the Control Panel as applicable to your operating system
Open “Network” (win 98) or Network Connections and Local Area
Connections/properties (Win XP)
• From the list of installed network components select and open “TCP/IP → xxx “ (Win
98) or “Internet Protocol (TCP/IP” (Win XP) that is installed on this PC. Check
System/Device Manager/Network Adapters under Control Panel to identify the correct
device
• Click Properties and “Specify an IP address” (Win 98) or Use Following IP Address
(WinXP)
• Enter 128.100.101.1, and Subnet = 255.255.0.0 . Click OK and Close
⇒ Power the RTMS and connect it to the PC network port using a network cable. Verify that a
correct cable is used by observing the PCs Network port Link and Activity indicator lights,
which should light
⇒ Open MS DOS prompt (under Programs) to ping the RTMS
Type C: \>ping 128.100.101.254 and observe response
⇒ If ping is successful, access the RTMS via a web browser (using the above network address)
On successful connection the Device Type page will be displayed. Select iServer from the
drop down menu and click Update to go to the home page, shown below.
⇒ Click Access Control
⇒ Enter Login password = 12345678 and Admin password = 00000000 when prompted (ensure
cursor is in the field before typing)
EIS Electronic Integrated Systems Inc.
RTMS User Manual
Issue 3.2

⇒ Overwrite the IP Address and the Subnet Mask with the desired settings and click Save.
Do not open and make changes in any other settings accessible from the Server Home page
⇒ De-power the RTMS to allow the microserver to reset itself
⇒ Connect RTMS to a network hub (or Ethernet bridge)
⇒ Repeat ping routine over the network using the new IP address to verify ( use an opposite
cable type to connect to a hub)
Recovery Procedures
The MAC (Media Access Control) is a unique hardware number associated with each ethernet
interface. This 6 byte number (12 hexadecimal characters) is furnished with RTMS shipping
documents.
Lost MAC or IP address can be recovered from the RTMS if one of them is known. If both are
lost, the sensor must be returned to EIS for recovery.
Recovery of MAC address
The MAC address can be obtained using a similar procedure to changing the default IP address.
Note that MAC address is included in the Access Control page.
An alternate method uses the ARP (Address Resolution Protocol) protocol supported by the
microserver. The ARP Internet layer protocol, which uses MS DOS Prompt, is responsible for
determining the MAC (hardware) address that corresponds to a particular IP address.
The “arp –a” command
allows the user to view the
current contents of the ARP
cache of the local computer
(residing on the same
network)
or
remote
computer (residing on the
different network) through
a router.
A device should be
”pinged” using IP address
before using “arp –a”
command as shown by the
sample session
IP address
Mac address
Recovery of IP address (MAC address known)
DNS (Domain Name System) enables individual devices to be recognized over a network based
on a Host name instead of an IP address. The default Host name for the microserver is "eis"
followed by the last four characters of the MAC address, e.g. eis178b.
