THEORY OF OPERATION
The TMA is a microwave sensor for traffic management (traffic data collection, intersection management, warnings,
public lighting management), available in different configurations according to the applications.
The TMA-296 is a microwave sensor for managing warnings and intersections. The output
consists of 2 relays which can be triggered on two different speed and range thresholds. The output can also be
read using a RS-232 serial communication.
1. Unpack the unit and check the following items are in the box (see Figure 1, p. 4):
A. Radar with rear side socket
B. Sticker for front face
C. Cable with connector
D. Mounting bracket
E. User’s guide and tune up procedure
2. Set the encoders according to your choice for the different parameters (see “Tune up procedure”). For the
TMA-296, it is also possible to make the setup through RS-232. The encoders are then inoperable.
3. Place the sticker on the front face.
4. Assemble the unit with the bracket (see “Tune up procedure”).
5. Place the radar on the field according to configuration and to the specific tune-up procedure.
6. Connect the cable according to title Wiring, p. 6.
7. Power the radar.
8. The LEDs will come on when a vehicle is detected and matches the conditions of the chosen parameters.

SAFETY PRECAUTIONS
Only skilled and instructed persons should carry out work with the radar product. Experience and knowledge about
safety procedures in the following areas may be relevant:
•Working with mains power
•Working with modern electronic and electric equipment
•Working at height
•Working at the roadside or highways
Please follow these safety precautions:
-Make sure the electricity supply is within the range shown on the label and the manual of the product.
-All connections must be made whilst the power supply is switched off.
-Ensure the wiring is correct as shown in the manual before switching on the power supply.
-Never use a damaged radar or cable.
-Opening the outer casing is deemed dangerous and will void all warranties.
-Ensure the radar is mounted correctly. The screws and bolts of both radar and bracket must be firmly
tightened. The radar needs to point to the region of interest for proper detection.
-Ensure the radar is configured properly.
WARNING: For the HV version of the radar, a Residual Current Device (RCD), also known as the Residual Current
Circuit Breaker (RCCB), with a tripping current not exceeding 30 mA must be installed in the supply circuit.

After configuring the radar, if the RS-232 port is not used during operation, it is strongly recommended that the
brown and green wires be connected together to ground the radar RX. This will prevent any parasitic effects in the
cable from unintentionally changing the radar configuration.
REMARKS
•Make sure the plug is fully inserted in the socket and the cap is firmly tightened on the socket.
•Please disconnect the radar from power before maintenance intervention.

PARAMETERS DESCRIPTION
Depending on the chosen TMA configuration, the settings are made using two encoding wheels with 16 positions
each and/or using an RS-232 link.
The parameters described here are for the TMA-296 configuration. Other parameters may apply to other TMA
configurations.
1 SENSITIVITY
The factory setting fulfills the requirements of the majority of the installations. If the position or the size of the
detection area is not satisfactory, change first the position of the radar (tilt angle and/or height of installation). On
some products, the sensitivity threshold can be lowered to reduce detections beyond the FSK ambiguity distance
(~250 m) and interfering movements at the edge of the detection area.
2 SELF-MONITORING
The self-monitoring applies to the following parts of the hardware:
- Micro-processor oscillator
- Code running
When a failure is detected, the relays are permanently actuated and the flashing LEDs show an error code (see
Tune up procedure for further information).
3 RF CHANNEL
This parameter allows to shift the radar’s frequency. If two units face each other, they must be put on different
channels as to not interfere with each other.
4 SPEED THRESHOLD
This parameter defines (a) minimum speed threshold(s) above which the relay is triggered.
5 RELAY TRIGGER
This parameter defines the logic for the relay triggering. It can be triggered for speeds above or under the chosen
threshold. This threshold is thus a minimum or maximum value for the relay activation.
6 PARAMETERS TO BE SET USING RS-232 SERIAL COMMUNICATION
6.1 DETECTION DISTANCE
This parameter defines the maximum detection range.
6.2 DETECTION DIRECTION
This parameter defines the direction of the movements which will trigger the relay: approaching, receding or
bidirectional.
6.3 MAXIMUM RELAY HOLD TIME
This parameter defines the maximum hold time for the relay in the absence of detection. When this time is elapsed,
the radar will release the relay, regardless of the presence of a vehicle.
6.4 OTHERS
See also p. 11 and following for a complete list of parameters that can be set via RS-232.

CONFIGURATION & TUNE-UP TMA-296
The TMA-296 is equipped with two encoding wheels for manual setting. It is also equipped with an RS-232 link
giving access to a wide range of parameters.
By default, the settings are made via the encoder wheels
At start-up, the LEDs indicate the version number and the type of configuration:
-Green and red LEDs flash alternately: relay check
-Flashing green or red LED: version number
•If the green LED flashes, the configuration comes from the encoder wheels
•If the red LED flashes, the configuration comes from the parameters sent via RS-232
If the radar has been configured via RS-232 and the position of an encoder is subsequently changed while the radar
is powered, the radar switches to encoder configuration.
To switch to the RS-232 configuration, it is necessary to switch the parameter to "RS-232" (see 2.2.1.1, p. 12).
1 SETTINGS WITH ROTARY ENCODERS
You can set different parameters through 2 encoders allowing 16 positions each.

Once you have set the requested radar
parameters, place the sticker on the front face to
guarantee its water tightness.

If the parameters are not changed via the RS-232 link, the TMA-296 operates as follows:
-Approaching traffic only
