3.1 CAN Bus Cabling Concept
In a test vehicle, several hundred sensors must be installed in many areas for the
testing phase, e.g. in the engine compartment and in the ground area. The sen-
sors distributed over the entire vehicle must then be connected with the measur-
ing devices of the test setup.
Today's standard solutions with a central setup of the measuring devices in the
passenger compartment require a complex cabling of the widely distributed sen-
sors with the measuring devices. Numerous, mostly long connecting cables
between sensors and measuring devices, combined into several thick cable har-
nesses, demand a heavily modified fire wall of the test vehicle. This causes long
setup times and high costs.
With the ES300 modules, ETAS offers a decentral solution that significantly sim-
plifies the measuring set-up of the sensors.
The basic idea of this concept is to install the modules of the ES300 series spa-
tially as close as possible to the sensors, to chain the modules with each other
and to connect only the first module of this chain with the laptop in the vehicle.
The ES300 modules from ETAS are independent measuring modules that pass
the measuring signals over the CAN bus. They can be operated individually as
well as in combination with other modules from ETAS.
3.2 Properties of the ES300 series
3.2.1 Advantages of the Decentral Cabling Concept
• The compact ES300 modules can be installed close to the sensors with
short connecting cables.
• The simple assembly and cabling principle (daisy-chain topology) of the
modules
– requires only on common cable between the modules for the power
supply and the transmission of data,
– significantly reduces the setup times for the tests, and
– simplifies the maintenance and expansion of the measuring setup.
• Only the laptop has to be accommodated in the vehicle, which is con-
nected with the modules using a single cable.
• Test vehicles equipped with a ES300 measuring system can be used in a
flexible way since the vehicles do not have to be modified for changed or
new test assignments.

4.3 Housing
The ES31x utilizes a robust metal housing with connections at the front of the
unit. The ES31x is designed for installation in the engine compartment.
The housings of the ES300 series can be connected with each other quickly and
easily to form a measuring system (see chapter 6 on page 25). In the vehicle or in
the lab, the modules can be screwed directly onto a carrier system without much
effort or fastened with cable ties.
These simple and uncomplicated fastening options allow for a flexible assembly
of the modules. On top of that, a high degree of availability of the fastening
options is also given under rough harsh ambient conditions (salt mist, dirt).

5.1 Sensor Connections
All sensor connections of ES31x feature identical designs. Each sensor connec-
tion consists of the function groups signal processing and filter as well as sensor
power supply.
5.1.1 Signal Processing and Filter
In every sensor connection, a capacitively compensated voltage divider limits the
level of the input signal after the overvoltage protection. An amplifier matches
the input signal to the following analog anti-aliasing filter according to the selec-
tion of the input voltage range.
An A/D converter digitizes the output signal of the analog filter. The separate A/
D converter that is integrated in every sensor connection ensures the synchro-
nous sampling of the measuring signals.
A digital filter then processes the digital signal. The digital filter can be config-
ured in the application program. At the output of the digital filter, the data is
written into a data buffer, where they are available for the query by the applica-
tion program.
Scaling of the measuring ranges
Depending on the channel, different measuring ranges are available which can
be configured on an individual basis.
Adjustability of the filter
To avid aliasing effects, a hardware filter can be activated. The hardware filter is
especially recommended for measuring periodic signals.
Averaging (moving average) smoothes undesirable signal jumps or noise compo-
nents.
The software filter enables an additional signal filtering. For this purpose, the
filter type and the cutoff frequency are selected.
5.1.2 Electrical Isolation
The sensor connections and the individually adjustable sensor supply voltages are
electrically isolated to each other, to the other channels, to the supply voltage
and to the CAN bus.

ES31x.1 User’s Guide20
Functional Description ETAS
5.1.3 Sensor Supply
Every sensor of ES31x that can be activated has its own separate, individually
adjustable sensor supply voltage.
The sensor supply voltage can be changed. The user can switch off the sensor
supply voltage of every sensor connection in the application program or select
one of the default values between +2.5 V and +15 V.
In case of a short circuit of the sensor supply output to ground, the sensor power
supply automatically switches off this channel. Each sensor supply output is pro-
tected against overvoltages. Exceeding the maximum value trips a fuse. In case
of short circuits and tripped fuse, the application program receives analyzable
channel-specific information.
5.2 Data Transmission
5.2.1 Design
The ES300 modules use the CAN bus standard CAN 2.0 B (29 bit identifier) for
the data transmission.

The supply voltages of the sensors are not electrically isolated towards the
operating voltage of the module.
