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.

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.
