RTMS User Manual Issue 3.2 1 EIS Electronic Integrated Systems Inc. 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. 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. Fig 2. RTMS Mounting Configurations Sidefired Configuration Forward-Looking ConfigurationPoleOverhead structure 40° Range slice
RTMS User Manual Issue 3.2 2 EIS Electronic Integrated Systems Inc. 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. 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.

Installation steps • Secure mounting bracket to the pole or overhead structure facing the traffic lanes to be monitored, using stainless steel bands or bolts. See RTMS Mounting and Aiming section for the required set-back and mounting height. • The ball-joint must point downwards as illustrated. Fig 4. Installation of RTMS bracket • Insert the RTMS mounting pin into the ball-joint, taking care not to kink the rubber grommet. Lubrication is recommended (e.g. WD40). ••
RTMS User Manual Issue 3.2 4 EIS Electronic Integrated Systems Inc. • 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 User Manual Issue 3.2 5 EIS Electronic Integrated Systems Inc. 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. Fig 5.

RTMS User Manual Issue 3.2 6 EIS Electronic Integrated Systems Inc. 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) Fig 6. 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. • Fig 7. Sidefired mounting on heavy structures EISEIS EIS EIS
RTMS User Manual Issue 3.2 7 EIS Electronic Integrated Systems Inc. Sidefired mounting in Intersection Stop Bar Detection Fig 8. 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 set-back, 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. • Optimal pole locations Non-optimal pole location
RTMS User Manual Issue 3.2 8 EIS Electronic Integrated Systems Inc. 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. Fig 9. Mounting on overhead structure in Forward-looking configuration. Incorrect aiming will result in poor accuracy. Aiming adjustments may be needed during setup, where verification is performed using a PC. Fig 10. Correct and incorrect aiming in Forward-looking configuration Offset of RTMS in Forward-looking configuration Forward-looking RTMS may be mounted on a roadside pole, if the offset (distance from sensor to lane centerline) is less than 3m (10 feet). Extension arms can be used to reduce offset. Fig 11. Offset Forward-Looking RTMS Mounting 20 ft max. Extension arm on pole Offset Sensor not level –footprint is skewed Sensor aiming not parallel to lane – footprint extends intoneighboring laneSensor mounted too high or aimed too far – footprint is wider than one lane Sensor aimed correctly – footprint contained within one lane and is long enoughSensor aimed at a sharp angle– footprint is short, beam is aimed at roofs of vehicles Correct
RTMS User Manual Issue 3.2 9 EIS Electronic Integrated Systems Inc. 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.
RTMS User Manual Issue 3.2 10 EIS Electronic Integrated Systems Inc. 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 ⇒ Select YES on these windows to try reading again after attempting to change Data mode or port speed. Selecting NO will display a default RTMS Setup screen with COM Port and Speed settings shown at the bottom right corner of the screen. They may be changed, if incorrect. See Section 5, Non-setup Functions of the Setup Utility for details. Once communication with RTMS is established (Data mode is NORMAL), the main screen display will show the following: • A blinking circle/square messaging “lamp” in the lower-right screen-corner indicates that WinRtms is receiving data from RTMS. (RTMS transmits “Target” messages 10 times per second) • Sensor parameter settings are shown on the Setup screen buttons. If not, Select READ RTMS. If unsuccessful, See Section 9 – Trouble Shooting. • Detection zone icons below the range scale, based on the present setup • Target “blips” are displayed in their correct range when vehicles cross the sensor beam • Per zone traffic data is updated at the end of every Message Period, along with a distinctive sound.
RTMS User Manual Issue 3.2 11 EIS Electronic Integrated Systems Inc. WinRtms Setup Utility Screen Fig 12. RTMS Setup Utility communicating with the sensor The screen bottom line display depends on the Model and Revision version of the RTMS. Always shown are the PC COM port, its speed and the setup date. RTMS Model X3/K3 with Rev 6.1 or higher displays additional info at the bottom of the screen: • RTMS serial number and Rev. version whenever the RTMS setup is read • If RTMS output includes real time clock, the above is displaced by date and time of day, • Time remaining to next message • Input power voltage. Note: The displayed voltage is the DC measured at the input (if powered by AC, its voltage multiplied by 1.4). If voltage exceeds 25.5V, the Model identification will be displayed instead, e.g. X3 ⇒ Date of last setup change in the RTMS.

RTMS User Manual Issue 3.2 13 EIS Electronic Integrated Systems Inc. Automated Wizard setup The WinRTMS Wizard feature (RTMS X3/K3 Rev.6.1 and up only) automates the setup stages: Sensitivity, Fine tune and Zone setup, allowing the operator to make interactive corrections in SideFired mode. Before proceeding to full Wizard setup, ensure that aiming is correct, i.e. target blips corresponding to vehicles in lanes of interest are visible on the screen. ⇒ Click the Wizard icon to initiate automatic setup. ⇒ Select the RTMS operating mode from the presented window (see next page for details of the RTMS modes) The Wizard will proceed to set Sensitivity and initial Zone Setup, defining up to 8 zones in range slices where traffic is detected, presenting its recommendation for approval. Verify visually (using vehicle blips) whether zones were placed on all lanes of interest. If they are, press SKIP. If not, press OK to manually change the number of zones and their location. Specifically, correct the position of the closest and farthest zones, then Click OK to proceed. This step ensures optimization of the setup on the lanes of interest only. See Zone Setup section. NOTE: Don’t worry about some splashing at this point. The Wizard will continue the automatic setup with Fine Tune and final Zone Setup. At the conclusion of the Wizard setup, some lane reconfiguration may be required due to traffic conditions. Finally speed calibration or other additional parameters can be executed. Aiming Verification and Manual Sensitivity setting Select the SENSITIVITY button to open the RTMS SENSITIVITY SETUP window. ⇒ Use UP/DOWN keys or click UP/DOWN arrows on screen to set to a medium value of 7. (Set to 5 if only a few close lanes are monitored) ⇒ Increase Sensitivity if needed to detect small vehicles in the middle lanes of interest. Reduce setting if a “Sensitivity too High” warning is displayed continuously. If small vehicles in either close or far lanes are missed, aiming should be adjusted. Tilt the sensor towards the zones of poor detection. Do not increase Sensitivity to compensate for improper aiming. ⇒ For manual setup, to force the “capture” of a new background quickly after aiming changes, increase the Sensitivity by one and restore it back. ⇒ Press ENTER or click OK to activate the new value and exit this window
RTMS User Manual Issue 3.2 14 EIS Electronic Integrated Systems Inc. RTMS Operating Modes ⇒ Select MODE button to open the RTMS MODE SETUP window. ⇒ Select the required mode for your application. The Mode selection loads the RTMS with several parameters, optimizing its performance for the selected application. The characteristics of available modes and their default settings are: Sidefired Highway Sidefired sensor detects presence and generates traffic data in up to 8 zones. Used in highway and counting applications. RTMS X2/K2 to X3/K3 Rev 6.0 provided two length classifications. Rev 6.1 and up provide two more classes. See Advanced Parameters for further details. Default settings: EDT = 200 msec, Threshold = Normal Intersection Sidefired sensor detects presence only (no traffic data is generated) in multiple zones. Used in Stop-bar detection Default settings: EDT = 1000 msec, Threshold =Low. Mid. Intersection Similar to Sidefired Highway mode, this mode is for use in mid-block 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. Forward Look Hwy Used in applications demanding high accuracy of speed measurements such as Speed Enforcement. Zones 1, 2 and 3 are set as a speed trap for accurate speed measurements. RTMS X2 Rev 4.3 or higher, provide per vehicle Doppler-based speed measurement when speeds exceed 15Km/h (10MPH). Volume data in up to 7 speed-bins is available. See Advanced Parameters for further details Default settings: EDT= 200 msec, Threshold = Normal Alarm Forward Look Similar to Forward-Looking Hwy mode in RTMS firmware version 5.X and higher. Adds programmable Speed threshold and real time contact #8 closure (for 20ms) when a vehicle exceeds threshold. Intended for use in speed enforcement and warning applications. Default settings: EDT= 200 msec, Threshold = Normal.
RTMS User Manual Issue 3.2 15 EIS Electronic Integrated Systems Inc. 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.
RTMS User Manual Issue 3.2 16 EIS Electronic Integrated Systems Inc. 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. Fig 13. Zone icons and target blips 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. Zone icon (Number shown) Target blip in configured zone Target blip not in a configured zone e.g. barrier (ignored) 12.5V
RTMS User Manual Issue 3.2 17 EIS Electronic Integrated Systems Inc. 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”. 4 5 6 7 3 4 5 6 6 12345612345677123456788899916 17 18 16 15 16 17 14 17 18 19 15 13 19 FT= +5 FT= 0 FT= -4 1 2 Lane # 145 815 16 17 18 Range Slice numbers Acceptable Zone setup at FT= -4 64 Acceptable Zone set-up at FT= +51 2 3 4 5 6 Zone Setup display 3 Splashing at FT=0 1 2 3 1 2 3 5 6 715 Distance scale 0 10 20 30 40

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.

RTMS User Manual Issue 3.2 20 EIS Electronic Integrated Systems Inc. Parameter Description Speed Bins Opens a window used only in Forward-Looking mode. See section on Additional Forward-Look Parameters below Power Management (Model X3/K3 only) Power Management allows conservation of battery power in battery or solar-powered applications by operating the RTMS in programmable cycles. The RTMS must be factory-ordered with this option. Two parameters are defined: • Number of Message Periods (min of 3 suggested) the sensor operates (0-254). It will go into standby 1-second after the last period. • Number of minutes the sensor is in standby and draws minimal power (0 to 254). ⇒ Set the above as desired or set Number of cycles and Standby time to 0 or 255 to turn Power Management off. Classification RTMS X2/K2 to X3/K3 Rev. 6.0 define only two vehicle classes, with Long Vehicles being at least three times longer than average small vehicles. RTMS X3/K3 Rev. 6.1 and up add length classes: Mid-size and Extra Long vehicles. All length classes are now user definable by specifying a multiplier based on average small vehicle. ⇒ Click to open a window displaying multipliers ⇒ Use LEFT/RIGHT keys to highlight a selection ⇒ Use UP/DOWN keys to adjust multiplier in steps of 0.1 Note: Vehicle class counters are incremented when vehicles passing the detection zone fall between class limits, e.g. if Long Vehicle multiplier is 3.5 and Extra Long Vehicle multiplier is 5.0, only vehicles with length between these multipliers will be reported as Long Vehicles. All classes are included in the volume count. Deduct the three classes and the remainder are average vehicles (fourth class). Note: Long Vehicle volumes will not be reported if Headway is selected or if Message Period is higher than 300 seconds.
RTMS User Manual Issue 3.2 21 EIS Electronic Integrated Systems Inc. Additional Forward-Looking Parameters Setting of additional parameters is required when any Forward-Looking mode is selected. Height and Offset The SPEED CORRECTION window showing Height and Offset parameters is opened automatically when these modes are selected. These parameters provide data for correction to the Doppler speed measurements due to the angle of the beam: Height Mounting height of the sensor above the road surface (e.g. 50 dcm or 17 feet). Note: Doppler not active if set to “0” Offset Distance from the sensor to the centerline of the monitored lane ⇒ Use LEFT/RIGHT keys to highlight a parameter ⇒ Use UP/DOWN keys to change the value ⇒ key ENTER (or click OK) to exit the screen when desired values are displayed. Alarm Speed Limit When Alarm Forward-Looking mode is selected, an additional ALARM LIMITS window opens automatically: ⇒ Use UP/DOWN keys to set the alarm speed limit ⇒ Key ENTER or click OK when desired limit is displayed. Speed bins The user can specify up to 7 speed-bins for data collection. Bin counters will be incremented by vehicles traveling between the specified speed limits. The count of vehicles for which the sensor was unable to determine speed is placed in the 8th bin. ⇒ Make sure the English/metric selection is as required before proceeding ⇒ Use LEFT/RIGHT keys or mouse click to highlight a bin. ⇒ Use UP/DOWN keys to set the bin’s upper speed limit. The upper limit setting of a bin automatically defines the lower limit of the next bin. To reset previous settings, reduce each bin to minimum and set to desired level. ⇒ Key ENTER or click OK to confirm when all required values are displayed
RTMS User Manual Issue 3.2 22 EIS Electronic Integrated Systems Inc. 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
RTMS User Manual Issue 3.2 23 EIS Electronic Integrated Systems Inc. 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.
RTMS User Manual Issue 3.2 24 EIS Electronic Integrated Systems Inc. Sidefired Manual Speed Calibration ⇒ Select SPEED CALIB button and tap the space bar. The displayed Manual Speed 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 next message period. ⇒ 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 Forward- Looking 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 . ⇒ Click OK to exit 100 96-3 +3

RTMS User Manual Issue 3.2 33 EIS Electronic Integrated Systems Inc. 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 # of pairs Power 1 pair Communication Port (one of 3 choices below) RS-232 (standard) 2 pairs, 3 pairs when DSS option is provided RS-485 (option) 3 pairs TCP/IP (option) 2 pairs, max 10m (30’)- Use CAT5 for cable up to 100m (300’) Zone Contacts 1 pair per zone. Fail safe 1 pair Auxiliary 12V DC power out 1 pair For more details on wiring of the Communication port see the section on RTMS Serial Communication and Cabling. Fail safe is provided in conjunction with the use of the RTMS Interface Card (RIC) by contact #9, which is closed when RTMS is powered, operational and in Normal data mode. In preparing a cable: ⇒ Use the Daniels Manufacturing Corporation crimping tool M225200/1-01 AF8 with head no. M22520/1-02) or equivalent. Do not solder pins! ⇒ Thread cable through the backshell before insertion of wires into shell is started. ⇒ Use the Insertion tool (red) to insert wires with crimped pin into shell. ⇒ Use the Extraction tool (white) to remove a crimped wire to correct an error WARNING: DO NOT connect the cable shield or ground wire to the MS Connector’s shell

RTMS User Manual Issue 3.2 35 EIS Electronic Integrated Systems Inc. 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. Abbreviation & Full Name Direction Function DB9 pin # DB25 pin # DCD Data Carrier Detect DCE to DTE Carrier received 1 8 Rx Receive data DCE to DTE Receive Data (by DTE) 2 3 Tx Transmit data DTE to DCE Transmit Data (by DTE) 3 2 DTR Data Terminal Ready DTE to DCE DTE ready to receive data 4 20 DSR Data Set Ready DCE to DTE DCE in communication mode 6 6 RTS Request To Send DTE to DCE DTE has data to send 7 4 CTS Clear To Send DCE to DTE DCE ready to receive data 8 5 Gnd Signal Ground Return path for Tx and Rx 5 7 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 User Manual Issue 3.2 36 EIS Electronic Integrated Systems Inc. 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 as follows: Twisted Pair 1 • MS pin V (red) to DB-9 pin 2 (Rx) • MS pin U (black) to DB9 pin 5 (Gnd) Twisted Pair 2 • MS pin T (red) to DB-9 pin 3 (Tx) • MS pin W (black) to DB-9 Pin 5 Fig 21. RTMS RS-232 Port Wiring RS-232 Port wiring – for RTMS with DSS Option When the internal DSS Modem option is included, the RS-232 port wiring requires another wire. ⇒ 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 RS-232 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.

See Appendix 1 for further details on multi-drop configuration wiring. TCP/IP (Ethernet) Port Wiring MS Connector pins X, Y, d and e are assigned as the TCP/IP port Rx+/ Rx-, Tx+/ Tx- leads respectively. Two twisted pair ethernet wiring standards employing RJ-45 connectors are in common use, T568A and B. These differ by interchanging transmit and receive pairs. CAT5 stranded-wire cable must be used for lengths exceeding 10m (30 feet) to a max. of 100m (300 ft). The shown MS connector to RJ-45 wiring conforms to T568B standard.

RTMS User Manual Issue 3.2 38 EIS Electronic Integrated Systems Inc. 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.

RTMS User Manual Issue 3.2 42 EIS Electronic Integrated Systems Inc. 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 speed-trap 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.
RTMS User Manual Issue 3.2 43 EIS Electronic Integrated Systems Inc. 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: Symptom Possible causes Suggested action “RTMS is not responding…” message continues to be displayed after attempts to set the sensor to Normal mode Power failure Cable problem Hardware • 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) • Alternate serial option (see cabling sections)

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: Modem-sharing Cable Construction Connection type DB9 to DB9 (modem side) DB9 to DB25 (modem side) ⇒ Transpose Tx and Rx Pins 2 to Pin 3 Pins 3 to Pin2 Pins 2 to Pin 2 Pins 3 to Pin 3 ⇒ Connect Signal Ground Pins 5 to Pin 5 Pins 5 to Pin 7 ⇒ Strap RTS to CTS Pin 7 to Pin 8 on modem side DB9 Pin 4 to Pin 5 on modem DB25 ⇒ Strap DTR to DSR Pin 4 to Pin 6 on modem side DB9 Pin 6 to Pin 20 on modem side DB25 ⇒ Connect a 100kΩ resistor from Tx to ground to prevent noise Pin 3 to Pin 5 on modem side DB9 Pin 2 to Pin 7 on modem side DB25 Fig 25. Modem sharing Y-cables 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
RTMS User Manual Issue 3.2 46 EIS Electronic Integrated Systems Inc. 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 Fig 26. Multi-drop wiring configuration For distances up to 4000 feet multi-drop configuration may employ the RS-485 Serial Port option. Maximum number of units is 32. The communication line can be configured as 4-Wire (shown in Fig. 27) or 2-Wire half-duplex (RTMS cannot transmit while its receiving) suitable for data collection operation only. Consult RS-485/422 Application Guides for details on 2-Wire configuration Fig 27. 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. 4 Wire Transmission lineRTMS ModemRTMSModemRTMSModemSee Fig 22 for pin assignment Last RTMS First RTMS Max. 4000 feet 5 1 2 3 4 Tx+ Rx+ Tx-Rx-Gnd U /W X T V Y 5 1 9 6 • • • • • • • • • • DB9F connectors DB9M connectors5 1 2 3 4 Tx+ Rx+ Tx-Rx-Gnd U /W X T V Y 5 1 9 6 • • • • • • • • • • Tx Rx + Sig.

RTMS User Manual Issue 3.2 47 EIS Electronic Integrated Systems Inc. APPENDIX 2 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)
RTMS User Manual Issue 3.2 48 EIS Electronic Integrated Systems Inc. ⇒ 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 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. Mac addressIP address

APPENDIX 3 INTERNAL DSS MODEM SETUP If the internal DSS modem fails to communicate with the master, as indicated by the red DSS rectangle it may be necessary to view and make changes in the DSS setup. To view setup ⇒ Click TOOLS button and PC COMM ⇒ Click DSS Modem button on the Communication Protocol Setup window ⇒ Ensure settings are: Slave mode for a simple line of sight communication to the master. Repeater if this modem relays data from another DSS modem, which is not in line of sight with the master. Additional fields will be displayed (shown) Roaming is on. This feature of the transceiver allows Slaves and repeaters to locate a master by the network address and encryption key and adopt its primary hopping pattern The DSS parameters and their ranges should be as follows: Advanced Par. Description Network Address This address must be same for all RTMS units and the Master in a specific system. Range 1-65535 Encryption Key This field must be set to the same value for all modems in a specific system, including Master. Range 1-65535 Hopping Patterns The Primary Hopping Pattern field must be filled with a hopping sequence (Range 1-63) for communication between the slave (or repeater) and the system master. The Secondary Hopping Pattern, displayed when Repeater is clicked, applies to communication between a repeater and its slave(s). It must be different than the Primary Hopping Pattern Unit Address Each modem must be set to a unique ID number within the system. Output Power Level Output power should be kept at the lowest setting, which provides reliable operation. 100 mW meets requirements of most applications. 1 mW or 10 mW may be sufficient in SPIDER applications at short ranges. Packet Size control Allows packets generated by slaves and repeaters to be of different size than masters. Packet fields Effective only if Packet Control is clicked. Min/Max Packet size Applicable to slaves and repeaters only if Packet size control is clicked. Otherwise Master settings take precedence.
