7.3 Speed read from wheel sensors
EVO5 has four wheel speed inputs, one in
the 37 pins connector and the other three
in the 22 pins connector:
The digital sensor X02SNVM00 detects
the presence of a metallic tooth placed at
a distance between 0.5 and 2 mm.
Please use the software Race Studio 3 to
load the sensor in the system configuration.
Just enter the program configuration panel
and, after enabling the desired speed chan-
nels, set the wheel circumference and the
number of pulses for revolution.
7. Speed
The system can receive the speed signal
from three different sources:
n
from the ECU
n
from the GPS receiver included in the kit
n
from the wheel sensors (digital channels)
It is therefore possible to receive and store
different values of speed at the same time;
the more powerful ECUs transmit up to four
wheel speed values.
7.1 Speed read from the ECU
If your ECU sends the value of speed in its
data stream, it is obviously possible to read,
record and show that value.
Simply enable it using Race Studio 3
software when setting the channels.
7.2 Speed read from the GPS receiver
The GPS receiver you find in the kit is
configured in order to obtain the best
performance in term of reactivity and accuracy.
For getting GPS speed you don't need any
configuration.
Simply connect the GPS08 Module to your
system and after a setup period of some
seconds the data will be received and
automatically recorded.

8. Analog inputs
EVO5 has 8 analog inputs, recorded up to
1000 times per second each.
You can connect:
n
0-5 Volt signals
n
Ratiometric potentiometers
n
Pressure sensors
n

n
K-type thermocouples
Please follow these steps, using the soft-
ware Race Studio 3 to set the channels:
n
Connect the sensor to the desired input
n
Enable the channel in the Channels table
n
Select the proper sensor type; sensors of
many different types are properly handled
n
Set the sampling frequency
n
Set the unit of measure.
