late the modules from the installation location.
CAUTION
Damage or destruction of the module is possible.
The modules of series ES400 are approved only for installation and operation
at components or locations that ensure compliance with the technical data of
the modules, such as:
• the resistance to vibration of the modules (for example, install modules
only on spring-loaded bodies, not on wheel suspensions or directly at the
motor) and
• the temperature resistance of the modules (for example, do not install
modules on the motor, turbocharger, exhaust manifold or their environ-
ments).

• “Wiring Concepts in Test Vehicles” on page 14

• “Housing” on page 16
• “Ports” on page 17

3.1 Wiring Concepts in Test Vehicles
For the test phase, several hundred sensors must be installed in a test vehicle
in various areas, e.g. in the engine compartment and in the floor area. The sen-
sors, which are positioned all over the vehicle, then have to be connected to the
measuring instruments of the test setup.
Today’s standard solutions with their central setup of measuring instruments
inside the vehicle require complex cabling to connect the widely distributed
sensors with the measuring instruments. Numerous, usually long connection
cables between the sensors and the measuring instruments, bundled together
to form several fat wiring harnesses, require a highly modified splash wall of
the test vehicle. This involves long setting-up times as well as high costs.
Fig. 3-1Central and Decentral Sensor Cabling
With the ES400 modules, ETAS provides a decentral solution which consider-
ably simplifies the test setup of the sensors.
The basic idea of this concept is to install the modules of the ES400 family as
close as possible to the sensors, to concatenate the modules with each other
and to connect just the first module of this chain with the laptop in the vehicle.

3.2 Features of the ES400 Line
3.2.1 Advantages of the Decentral Wiring Concept
• The compact ES400 modules can be mounted close to the sensors with
short connection cables.
• The simple assembly and wiring principle (daisy chain topology) of the
modules
– requires only one common cable between the modules for power
supply and data transfer
– considerably reduces the setting-up times for tests
– simplifies the maintenance and the extension of the test setup
• The only item in the vehicle is the laptop which is connected to the mod-
ules with just one cable.
• Test vehicles equipped with an ES400 measurement system can be
used flexibly because the vehicles do not have to be modified for
changed or new test tasks.
3.2.2 Further Features
This list provides an overview of the other features of the ES400 line in addition
to decentral cabling:
• The ES400 modules have a very compact design.
• Each module has an LED for localizing the module.
• The Counter and Frequency Module with Sensor Supplys of the ES400
family use a XCP-based protocol which is compatible to the existing
ETAS Ethernet topology.
The concept fulfills the following requirements:
– high bandwidth to be able to realize lots of channels with high resolu-
tions (typical in measuring and calibration applications) with fast
sampling rates
– simple application based on the Ethernet integration in INCA, no com-
plicated setting of bus parameters,
– simple to integrate in measurement and calibration tools manufac-
tured by third-party suppliers due to the use of XCP as application
protocol
– support of all probes and pressure sensors used in the automotive
industry
• Innovative, battery-saving power supply management
– automatic power-saving feature (“Standby”)
– “Wake Up” via the Ethernet interface
• Part of the ETAS Tool Suite
• Daisy Chain Configuration Tool (stand-alone operation)

ETAS ES400 Product Family
ES441.1 - User Guide 16
• Modules suitable for use in automotive applications; suitable for use in
the development environment and in the vehicle on test drives:
– Housing, connectors and cables waterproof and dustproof in acc.
with IP65 or IP67; designed for use in the engine compartment or the
outside area of the vehicle
– rugged to acceleration or mechanical damage
– rugged to extreme environmental conditions (temperature, damp-
ness, EMC)
– very low temperature coefficients contribute to the reduction in the
number of measurement errors
For the complete technical data of the ES441.1, refer to the chapter “Technical
Data” on page 92.
3.3 Housing
A sturdy metal housing is used for the ES441.1; it has ports on the front of the
device so it can fit into tight spaces. The ES441.1 is specifically designed to be
installed in engine compartment, but also in the passenger cell.
The housings of the ES400 family can quickly and easily be connected to one
another to create a measurement system (see section 6.2 on page 59). The
modules can easily be screwed directly to a carrier system or attached to it
using cable fasteners both in the vehicle and in the lab.
These simple and uncomplicated ways of attaching the modules make them
flexible in terms of assembly. These methods of attachment can also be used
in harsh environmental conditions (salt fog, dirt).
CAUTION
Loss of Features as defined by IP67!
Do not open or change the module housing!
Works on the module housing may be executed only by qualified technical
personnel.

ETAS ES400 Product Family
ES441.1 - User Guide 17
3.4 Ports
All ports of the ES400 measuring modules are on the front of the device (see
Fig. 3-2 on page 17).
The LEMO and Souriau connectors used adhere to protection class IP67. All
ports are reverse-polarity protected due to the exclusive use of coded LEMO or
Souriau connectors.
Fig. 3-2Front
3.4.1 “Sensor” Port
The front of the ES441.1 features a 22-pin Souriau port to which four sensors
can be connected using a adapter cable. An individual sensor power supply
port is available for each sensor.
The use of a “cable tail” or “whip” solution with just one connector makes it
possible to change the modules quickly within complex test setups.
3.4.2 Daisy Chain Ports (“IN”, “OUT”)
The modules are connected using a daisy chain topology. This means each
module has an explicit input socket and an explicit output socket. The Ethernet
data line and the supply voltage are routed through the daisy chain ports of the
module:
• “IN” (input)
• “OUT” (output)
The PC, the modules ES523, ES59x, ES600.2, ES891, ES910.3 or the Drive
Recorder ES720 are connected at the “IN” port (input). The “OUT” port (output)
is connected to the following module of the ES400 line or remains free on the
last module of the chain.

4.2 Block Diagram
The ES441.1 is a module with four identical measurement channels, its own
sensor supply for every measurement channel, two shared Ethernet interfaces
and a power supply.
Fig. 4-2Block Diagram
4.3 Measurement Channels
All measurement channels of the ES441.1 are identical. They consist of an
input stage with signal acquisition and signal processing.
The measurement channels are designed for input voltages of -50 V to +50 V.
The minimum pulse width is limited to 120 ns. This limitation avoids the acqui-
sition of interfering pulses on the measurement channels. The input imped-
ance is greater than 2 M.
4.3.1 Input Stage with Signal Acquisition and Signal Processing
Fig. 4-3Input Stage
The input stage of every measurement channel (see Fig. 4-3 on page 20) con-
sists of the following components:
• Schmitt trigger with a configurable hysteresis,
• galvanic isolation,
• interfering voltage filter,
• inverter and
• signal acquisition and signal processing.
