• "Housing" on page 17
• "Ports" on page 18
• "LED" on page 19
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 sensors,
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. 3-1 Central and Decentral Sensor Cabling
With the ES400 modules, ETAS provides a decentral solution which considerably
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.
ES441.1 - User’s Guide 15
ES400 Product Family ETAS
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 sup-
ply 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 modules 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)

CAUTION!
• 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, dampness,
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 102.
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 68). 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).
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.

3.4 Ports
All ports of the ES400 measuring modules are on the front of the device (see
Fig. 3-2 on page 18).
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. 3-2 Front
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.

4.3 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 acquisition of interfering pulses on the measurement channels. The input impedance is
greater than 2 M.
4.3.1 Input Stage with Signal Acquisition and Signal Processing
Fig. 4-3 Input Stage
The input stage of every measurement channel (see Fig. 4-3 on page 22) consists
of the following components:
• Schmitt trigger with a configurable hysteresis,
• galvanic isolation,
• interfering voltage filter,
• inverter and
• signal acquisition and signal processing.
Configurable Hysteresis
The hysteresis and the corresponding values for the LOW and HIGH levels can be
configured independently of one another in the calibration software (see Fig. 4-4
on page 22).
Fig. 4-4 Definition of the Hysteresis for the Input Channel
They can be configured separately in a range of -50 V to +50 V for every input
channel of the ES441.1. The minimum resolution of the switching thresholds is
0.1 V. The hysteresis is defined completely by both levels and the edge direction.
The configurable hysteresis results in noise suppression. This feature facilitates
application in environments with noise interference and/or noise signals. The
quality of signal interpretation is improved considerably.
ES441.1 - User’s Guide22
ETAS Hardware Description
Galvanic Isolation
The measurement channels are galvanically isolated from each other and from
the power supply.
Interfering Voltage Filter
In the input stage, an interfering voltage filter frees the input signal of short
interfering pulses. The filter characteristics (duration) can be configured in the
calibration software. The interfering voltage filter can be disabled if necessary.
Inverter
The input signal of every channel of the ES441.1 can be inverted independently
of the other channels if necessary. Selection takes place in the calibration software.
Signal Acquisition and Signal Processing
In this function group, the input signal is sampled and processed in accordance
with the measuring capability selected in the calibration software. Measuring
capabilities can be selected independently of one another for the measurement
channels of the ES441.1.
The measuring capabilities of the ES441.1 are described in chapter 5 on page 33.

4.3.2 Sensor Supply
Every sensor that can be switched to the ES441.1 has an individual sensor supply
voltage which can be set separately.
The cable connected to the sensor port of the ES441.1 transfers both the sensor
supply voltage and the sensor output voltage for the sensor. Additional cables or
an additional external power supply for the sensor supply voltage are not
required.
Fig. 4-5 Sensor Supply for a Sensor Channel
The sensor supply voltage is generated from the module operating voltage in
every sensor channel. The sensor supply voltage can be modified in steps. The
user can switch off the sensor supply voltage of each sensor channel in the application software, select one of the defined values between +5 V and +15 V or
enter or define any value within the value range.
With a short-circuit of the sensor supply output against ground, the sensor
power supply of this channel is automatically switched off. Every sensor supply
output is protected against overvoltage. A fuse blows if the maximum value is
exceeded. When a short-circuit occurs and a fuse blows, the application software
receives channel-specific information which can be evaluated.
The supply voltages of the sensors are not galvanically isolated from the operating voltage of the module.

4.4 Data Transfer
For data transfer, the ES930.1 as well as the ES4xx and ES63x modules use a
100 Mbit/s Ethernet network connection in duplex operation. The data transfer
can be adapted flexibly to suit the test setup and the measurement task.
The complete Ethernet bandwidth is available for both measure data and control variables.
Calibration procedures can take place in a Rapid Prototyping application without delay with measure data being acquired at the same time.
4.4.1 Communication Protocols
The universal ASAM measure and calibration protocol XCP is used for serial communication. On the Ethernet transport and network layer, the UDP/IP protocol is
used (see Fig. 4-6 on page 25).
Within the XCP protocol, the modules transfer, among other things, module ID,
time stamp and measure and/or stimulation data in an extremely precise and
predictable time pattern. The communication protocol used for the modules
avoids repeated transfer of protocol data, which takes place, for example, in
handshake-based systems. This makes a high bandwidth available for reference
data.
ES441.1 - User’s Guide 25
Fig. 4-6 Message Format “XCP on UDP” (Schematic)
Using the UDP/IP standard for data transfer makes it possible to connect the
modules directly to a PC, a router or a switch. In XCP communication, the PC has
the master function.
No real-time requirements are made. Data acquisition on a PC, which generally
Note
does not have to fulfil high real-time requirements, can thus be connected
directly to an ES400 chain. With a real-time-capable master, such as, for example, a Rapid Prototyping system, lots of different kinds of I/O signal can be
accessed with extremely short cycle times.
The communication protocol used by the ES400 family makes it possible for
third-party suppliers to use the communication protocol for their own, nonETAS applications once the modules have been configured with the „ES4xx
Configuration Tool from ES4xx_DRV_SW“ .
4.4.2 Realization
Time Slice Procedure
The modules in the daisy chain transfer the data to the master using a 100 MBit/
s Ethernet connection time-controlled, i.e. without being prompted. The PC
assumes the function of the master. In the network, the modules respond like a
single Ethernet device with one MAC address.
All daisy chained modules have a generator which is only activated in the last
module of each chain after the test setup has been connected to the PC. The
frequency of the generator or the period duration of the time slices generated
can be set in the application program. It corresponds to the measuring frequency
of the measurement channel with the highest acquisition rate in the chain.
A binary counter linked to the generator periodically counts the time slices generated (value range: 2
vant number of time slices in the IP header. The Ethernet frames are transferred
from module to module within the chain.
Each module in the chain receives bandwidth to transfer its measure data in
freely selectable time slices assigned within the period of the binary counter. The
module uses the number of the time slice to determine whether it can insert an
XCP message with its measure data into the current time slice.
The fastest module, which determines the period duration of the time slices generated, transfers data in every time slice. An Ethernet frame then contains at least
one XCP-on-Ethernet data package. The length of the Ethernet frame transferred inside a time slice increases with the number of modules which can insert
their data into this time slice.
The numbering of the time slices ensures, for example, that two modules which
work with half the sampling rate of the generator never attach their data to the
same Ethernet frame. One module uses only the odd frame numbers and the
other only the even ones. This mechanism also ensures for certain that the
assigned frames do not exceed the length of a time slice.
The measure data is automatically distributed to the frames so that the available
bandwidth is used perfectly.
The time slice procedure makes both measurements of fast signals and the acquisition of a large number of channels with a low sampling rate possible.

Note
If a few fast signals and lots of slow ones are acquired in a chain, the slow signals
can be transferred in time multiplex procedure.
Due to data transfer by Ethernet, there are virtually no limitations in terms of
the number of modules in a module chain even with fast sampling rates.
Clock Generator for Synchronizing Modules
The clock generator for the synchronization of the modules is either the first
module in an module chain or the network module ES600. In both cases, the
measure data is synchronized with a tolerance of one microsecond. Using an
ES600 network module, several ES4xx/ES63x/ES93x chains can be synchronized
with each other or with the modules of the ES600 series. The ES4xx/ES63x/ES93x
and ES600 modules add the relevant time stamp to the Ethernet data package
for every measure value. The exact assignment in terms of time of the measure
data of the ES4xx/ES63x/ES93x and ES600 modules used resulting from this
makes precise analysis of the correlations of measure signals possible.
Synchronizing the Modules and INCA Signal Processing
Data transfer does not require synchronization of the local timebases of the
ES4xx/ES63x/ES93x modules. The time stamps are still synchronized by the system to be able to correlate measure data and sampling times of different modules in terms of time after data transfer. A precise time and drift synchronization
takes place in the modules via a hardware connection.
No bandwidth is required for this, unlike time synchronization in acc. with
IEEE1588 (Precision Time Protocol). The modules add the time stamp to the
Ethernet data package for every measure date.
The combination of time stamp synchronization, full duplex and time slice procedure results in a very high reference data rate of the modules.

4.5 Power Supply
Note
4.5.1 Supply Voltage
DC/DC converters in every module guarantee both the operation as well as the
launch of the ES400 modules with supply voltages between 5 V and 50 V DC
over the entire temperature range.
With the power supply management of the ES441.1, you can use an automatic
power-saving feature (“Standby”) as well as a “Wake Up” function via the Ethernet interface.
4.5.2 Supplying the ES400 Modules via the Connecting Line
In the simplest application case, the modules are directly linked to one another.
They are connected to the supply voltage via the previous module all the way.
4.5.3 Additional Supply of the ES400 Modules via a Y-Boost Cable
If the supply voltage at the input of a module is too low because of the current
consumption of the previous modules, multiple feeding of the supply voltage can
guarantee this and the following modules sufficient supply voltage in longer
module chains.
In this application case, you have to split the module chain. Swap the existing
connection cable between the two modules for a Y boost cable for additional,
direct feeding of the supply voltage. The module chain is now closed again and
the power supply of the following modules guaranteed.
The special design of the Y boost cable avoids reverse feeding into the front parts
of the module chain and thus arising potential differences.
When is it necessary to use a Y boost cable?
ETAS
An exact calculation of the current consumption of a module chain is only possible if numerous variables are known:
• supply voltage of the first module at the input
• minimum supply voltage at the last module of the chain
• number and type of the modules
• consumption of sensor power supply of the connected sensors
• cable length
•cable type
• ambient temperature
The necessary minimum voltage for supplying power to the system must be
determined individually for each test set-up.
Please contact our local experts to discuss your particular ES441.1 configurations.
Example 1: For module chains which are equipped exclusively with ES410.1 or
ES441.1, ETAS recommends the use of Y boost cables if the length of the module
chain is longer than 10 modules.
