2. PLANNING

To achieve the most accurate measurement possible, planning the installation is essential.

Horizontal or Top Down?

The devices can be operated both directly next to the road or elevated and looking down from above. We recommend using a laser measuring tool or a laser pointer to align the device correctly.

	When mounted on a pole or mast you should point the sensor to the middle of the road (center line). This can be done easily by adjusting the tiltable bracket MT80-15. The bracket can be placed about 3-4 meters above ground. Please check the max range of the sensor. Important: The pole must not move in the wind
	When mounted next to the street we recommend a mounting height of 1.2-1.5m above ground. Line of sight should be completely horizontal.

Important Rules

The device works best when the following rules are observed.

	Lateral to movement TCR are side radars that detect motion from both directions simultaneously. The movement should be linear. Therefore place the sensor parallel to the movements direction and keep away from curves, crossings, driveways
	Distance to object LS-Devices: The sensor must be placed at least 50cm away from the target. HS-Devices: The sensor must be placed at least 3m away from the target.
	Avoid obstacles in FOV Make sure there are no obstacles such as walls, street signs, shrubberies, trees in the field of view. When placed beside water the device might detect the waves.

LTR vs RTL

The TCR traffic counters distinguish between 2 directions.

RTL
objects which come from the right and disappear to the left. The left LED will pulse once in this case.
LTR
objects which come from the left and disappear to the right. The right LED will pulse once in this case.

Measure distance to lanes

In order for the device to determine the velocities, the distance to the object must be known. The distance can be determined with a tape measure or a laser distance meter. Measurements are taken from the middle of a track to the front of the device.

• RTLDist = Distance in cm to the RTL movement line.
• LTRDist = Distance in cm to the LTR movement line.

Situation
	Two lanes, cross traffic (2L2D) This is typical for HS applications such as measuring traffic on interstate roads. RTLDist and LTRDist are different.
	Cross traffic on one lane (1L2D) This is typical for low speed traffic (LS) measuring bicycle lanes or small paths. In this case get the distance to the center of the track and set RTLDist and LTR Dist to the same value.

3. CONFIGURATION

Connect USB cable

Open the service lid and connect a USB-to-Micro-USB cable Connect the other end to a Windows PCs USB-Port. The RTL LED should start to blink.

Configure using PPX

While the device is connected to the PC open ppx.parametric.ch to access the online configuration tool. Follow the instructions on the screen to establish a connection.

Set Distance to Lanes

Once connected open Radar-Settings and find Left To Right Lane Distance and Right To Left Lane Distance

• Enter LTRDist value you measured in #measure-distance-to-lanes) into the field LTRDist
• Enter RTLDist value you measure in #measure-distance-to-lanes) into the field RTLDist
• Press Save

Sensitivity

Turn on autotune to allow the radar to adjust the sensitivity.

After entering LTRDist and RTLDist the sensitivity is automatically determined based on those values. The further the distance to the measurement, the higher the sensitivity.

Note: Small adjustments of sensitivity can be done manually. If the ratio (sensitivity vs. RTL/LTR) is not correct, the radar may incorrectly categorize the measured object.

4. INSTALLATION

Assemble M12 Plug

The scope of delivery includes an M12 cable round connector (TE T4112002081-000) with screw terminals. This is to be connected to a 12V power supply.

Please connect V- / V+ cables to Pin 1 and Pin 2. Use a screw driver #0 or #00 for this.

	Pin	Signal	Purpose
	1 2 3 4 5 6 7 8	V- V+	0V DC (-) 5-12V DC (+)

Connect M12 Plug

The M12 connectors have a coding notch (A Coding).

Important:

• Check the pins before plugging in

• Rotate the plug so that the notch matches the pin in the socket

• Carefully insert the plug by hand

• Gently tighten knurled screw by hand

Plug in the M12 connector onto the M12 socket on the right side of your TCR. Tighten the ring by hand.

Mount MT80

Carefully tighten the MT80-15 holder with the supplied screws. Use a 25 HEX screw driver for that.

Warning: Using longer screws could crack the enclosure.

Installing the Counter

If you mount the counter to a pole or mast use pipe clamps or metal straps of suitable length to secure MT80-15 bracket.

5. TESTING

Live Data Monitoring

Go outside to your TCR, connect the USB cable and start live measurements on site. While the device is connected to the PC open ppx.parametric.ch to access the online configuration tool.

Last Detection

Last Detection gives you an insight to the last radar measurement. This is what the radar “sees”.

Counters

Counters is a table with all Categories an left / right counter values. Values are updated regularely

Adjust your values

The main challenge with the TCR devices is to find a suitable Distance/Sensitivity Setting.

If the sensitivity is to high, the object might blur and therefore gets too big (Size value) If the distance is incorrect the size get too big too.

With Autotune enabled the Radar Sensitivity will be controlled automatically. It’s comparable to the automatic exposure setting at a photo camera.
