Brief Description
The RTMS (Remote Traffic Microwave Sensor) measures the distance to objects in the path of its
microwave beam. This ranging capability allows it to detect moving and stationary vehicles in multiple
detection zones.
The sensor can be mounted on road-side poles and aimed at a right angle to the road; refered to as the
side-fired configuration. A single sensor can monitor traffic in up to 8 lanes. Sensors may also be
mounted on overhead structures to monitor traffic in a single lane; the forward-looking configuration.
The internal processor calculates volume, occupancy and average speed as well as vehicle class by
length in each lane and transmits the information using its data port. Optional contact closure outputs are
also available for for compatibility with loop based systems.
For optimal accuracy, EIS strongly recommends installation of all RTMS and RTMS related
products by personnel trained by EIS.
EIS also strongly recommends surveying of installation sites for all RTMS and RTMS related
products by personnel trained by EIS.
For more information about our installation, surveying, and training programs, contact EIS at
1-800-668-9385.
WARNING: Consult EIS before using the RTMS or other RTMS related products for any
purpose not expressly described in this manual or any of the other RTMS product
manuals. Do not use the RTMS to control or operate a gate opening mechanism.
Use of the RTMS for this, or any other unauthorized purpose, may lead to serious
injury.

3 RTMS INSTALLATION – SIDE FIRED CONFIGURATION
Mounting and Aiming
The distance between the close edge of the first lane of traffic to be monitored and the front of the
structure on which the RTMS is mounted is referred to as set-back; it is the most important parameter in
the setup and installation of an RTMS. Generally the more set-back that can be obtained, the easier the
calibration will be.
Use the diagram in Figure 2 to determine the setback required to monitor a given number of lanes. Once
the set-back is set, the associated height can be determined. Height is with reference to the road surface
of the detection area; not the bottom of the mounting pole.
Example: For 5 lanes the minimum set-back should be 12 feet [3.7m].
A set-back of 12 feet [3.7m], requires a height of 17 feet [5.2m].
Note: It is better to be 20 feet [6 m] further back from the minimum than 2 inches [5 cm]
closer than the minimum. If ground conditions allow, move the RTMS further back.
The mounting height is based on the setback. Height is selected to allow the RTMS to be aimed so that
it gets maximum return signal while covering all required lanes. Mounting an RTMS at a height different
from the recommended height will not improve accuracy.
Equivalent lanes include median strips, as an example, an eight lane road with a two lane wide median
strip has 10 equivalent lanes.
•

line
Figure 1 – RTMS Aiming
• Attach the RTMS to the roadside pole using bolts or stainless steel banding.
• Aim the RTMS as indicated on the diagram above. A 7/16” wrench is required to release/tighten
the ball-joint bolt.
- Secure the RTMS to the mounting bracket by inserting the lynch pin
- Adjust the RTMS to be perpendicular to the travel lanes.
- Look from behind the unit and use the top aiming fin to tilt 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.
- Lock the aim by tightening the ball-joint bolt.

RTMS™ User Manual for Model K4 Draft 1 Page 3
Setback/Height diagrams
Figure 2 - Set-back Distance Chart
Equivalent lane calculation is measured from edge of first lane of detection to outside edge of the last
lane of detection and dividing this number by the average lane width. 12 feet is considered typical lane
width.
Example: total detection area = 120 feet; lane = 12 feet; 120/12 = 10 equivalent lanes
Figure 3 – Mounting Height Chart
If more room is available increase the setback as much as possible; then obtain the proper mounting
height based upon actual set-back distance.

4 CABLING
Surge suppression
Although the RTMS has built-in surge suppression, it is strongly recommended that external surge
suppression be installed with every detector. In situations where long cable runs are utilized, the
communication and power lines of the RTMS should be equipped with external surge protecting devices
on the same pole as the detector. The suppression devices should be located close to the sensor; e.g.
in a cabling cabinets mounted on the pole below the RTMS. See Appendix 1 for further details on
installing surge suppression.
The RTMS Cable
RTMS units use a single 32-pin MS connector for power and communications. The RTMS ships with all
required connectors, crimp pins and back-shells.
The RTMS cable should be made from 20 or 22 gauge stranded wire arranged in pairs. Cables that will
be exposed to outdoor conditions should be UV shielded. The number of pairs required depends on the
communication options chosen:
Table 1 – Cable pairs required
Communication Options # of Pairs
Standard RS232 or RS485 plus power 4
Standard RS232 plus power and Internal RF modem option 4
TCP/IP and RS232 or RS485, plus 6 power
Zone contact option can be added to any of the above 1 per zone (max 8)
A cable such as the Belden number 95xx (xx indicates number of pairs, i.e. 9516 is a 6-pair cable) or
In preparing a cable note the following:
• The crimp pins are designed for stranded wire. Do not use cable employing solid wires
similar should be used.
.
• EIS suggests the Daniels Manufacturing Corporation crimping tool M22520/1-01 AF8 with head
no. M22520/1-02 or equivalent. Do not solder crimp pins!
• Thread cable through the backshell before inserting pins into shell.
• 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.
• It is recommended to use a cable with at least one spare pairs of wires for future growth.
Consideration needs to be made with regards to placement of an access point within view of the
monitored lanes, as an example, an access panel or cabinet on the pole. This allows verification of the
sensors calibration to be easily be done by seeing the RTMS data together with the actual roadway data.

ject.
The RS-485 Serial Port option may be employed for distances up to 4000 feet (1200m). The maximum
number of units per channel is 32.
The diagram below shows the use of a 4-Wire line. The use of a half-duplex 2-Wire line is feasible but it
is suitable for data collection only. Consult RS-485/422 Application Guides for details on wiring solutions
for your pro
Figure 11 - RS-485 Multi-drop wiring
Notes:
1. The DB9 connectors and terminal blocks serve as a demarcation point, which allows unplugging the
RTMS from the transmission line for direct connection to the laptop’s COM port for setup.
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 DTE (PC, Data processing
System). To interface with a PC a RS-485/232 converter may be required as PCs typically do not
have RS-485 interfaces
4. RS-485/232 converter connector type and pin assignment are not shown as these are not
standardized and vary between models.

• Mount the sensor above the center of the lane at a height between 5m

a sufficiently long footprint but restrict its width to a single lane.

Figure 16 - Forward Looking mounting options
Figure 17 – Queue Detection
RTMS can be set up in forward looking mode when serving off-ramp or T-intersection queue
applications. In such applications, the RTMS is aimed farther than in the traffic monitoring highway
applications. One or more detection zones are defined to span the required distance (within the range
limit of the RTMS). The width of the microwave beam may cover two lanes; the sensor cannot
discriminate between lanes.

The Wizard will determine 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
• Set the number of zones to 8 and position all zones in sequence with the first zone at
approximately 8 meters 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 or aimed too high.
• Set Fine Tune control to +5.
• Observe approximately 50 vehicles. Find three consecutive zones, for which vehicle counts are in
close agreement with each other. The location of these three zones will form the speed-trap. Note
their position on the ra bers 1, 2 and 3 over these
three consecutive zone positions, then reduce the total 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 determine the direction of travel.
Forward-Looking Speed calibration
The RTMS provides Doppler speed measurements and does not need to be calibrated for this, only the

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 may slightly over-count at
conditions (below 1mph)
• Improper selection of installation site: insufficient set-back, height beyond the recommendation,
obstruction of monitored lanes by barriers or high fences.
• Improper fine tune setting for the road geometry (lane width,
and, therefore, over-counting. In some cases, attempts to cover too many traffic lanes with a single
RTMS may result in inability to find a correct fine tune setting and compromised performance.
In Forward-Looking Hwy configuration, high variance between the volu zones due to improper aiming o
parameters may result in higher speed and length measurement errors.
