with EN 61140 (degree of protection III) to the connections of the mod-
ule.
• Ensure that the connection and setting values are being followed (see
the information in the chapter "Technical data").
• Do not apply any voltages to the connections of the module that do not
correspond to the specifications of the respective connection.
Power supply
• The power supply for the product must be safely disconnected from the
supply voltage. For example, use a car battery or a suitable lab power
supply.
• Use only lab power supplies with double protection to the supply net-
work (with double insulation/reinforced insulation (DI/ RI)).
• The lab power supply must be approved for an operating altitude of
5000 m and for an ambient temperature of up to 70 °C.
• In regular operation of the modules as well as very long standby opera-
tion, a discharge of the vehicle battery is possible.

ETAS Basic Safety Notices
ES523.1 -User Guide 11
Connection to the power supply
• The power cable must not be connected directly to the vehicle battery or
lab power supply, but via a fuse of up to 20 A.
• Ensure that the connections of the lab power supply, the power supply at
the module and the vehicle battery are easily accessible!
• Route the power cord in such a way that it is protected against abrasion,
damages, deformation and kinking. Do not place any objects on the
power cord!
Disconnecting from the power supply
The module does not have an operating voltage switch. The module can be de-
energized as follows:
• Disconnecting the module from the lab power supply
– Separating device is the lab plug of the power cord or
– Separating device is the plug of the power cord at the connection of
the module
• Disconnecting the module from the vehicle battery
– Separating device is the lab plug of the power cord or
– Separating device is the plug of the power cord at the connection of
the module
• Disconnecting the vehicle battery.
Approved cables
• Use exclusively ETAS cables at the connections of the module!
•Adhere to the maximum permissible cable lengths!
• Do not use any damaged cables! Cables may be repaired only by ETAS!
• Never apply force to insert a plug into a socket. Ensure that there is no
contamination in and on the connection, that the plug fits the socket, and
that you correctly aligned the plugs with the connection.
Requirements for the location
• Position the module or the module stack on a smooth, level and solid
underground.
• The module or the module stack must always be securely fastened.
DANGER
Dangerous electrical voltage!
Connect the power cable only with a suitable vehicle battery or with a suitable
lab power supply! The connection to power outlets is not allowed!
To prevent an inadvertent insertion in power outlets, ETAS recommends to
equip the power cables with safety banana plugs in areas with power outlets.

Fixing the modules on a carrier system
• When selecting the carrier system, observe the static and dynamic
forces that could be created by the module or the module stack on the
carrier system.
Requirements on the ventilation
• Keep the module away from heat sources and protect it against direct
exposure to the sun.
• The free space above and behind the module must be selected so that
sufficient air circulation is ensured.
Assembling (interconnecting) the modules
• Prior to assembling (interconnecting) or separating a module stack, the
modules must be disconnected from the supply voltage or they have to
be in the standby operating mode.
Transport
• Stack and connect the modules only at the location of the startup!
• Do not transport the modules at the cable of the module or any other
cables.
Maintenance
The product is maintenance-free.
Repair
If an ETAS hardware product should require a repair, return the product to
ETAS.
Cleaning the module housing
• Use a dry or lightly moistened, soft, lint-free cloth for cleaning the module
housing.
• Do not user any sprays, solvents or abrasive cleaners which could dam-
age the housing.
• Ensure that no moisture enters the housing. Never spray cleaning agents
directly onto the module.
Ambient conditions
The housing and the connectors of the module as well as the plug connectors
of the cables meet the degree of protection IP30.

4 Hardware Description
This chapter provides you with an overview of the ES523.1 with information on
the housing, serial number, ports and LEDs.
4.1 Overview
The ES523.1 module is a powerful ECU and bus interface modules. It has an
upstream Ethernet interface that guarantees data exchange with the host PC or
with a Drive Recorder. The ES523.1 module has three downstream Ethernet
interfaces that can be connected with ES59x, ES600, measurement and inter-
face modules.
Fig. 4-1View of the Device
Measurement, calibration and rapid prototyping modules are easy to combine
with ES523.1 modules. ECUs that have an XETK, or ECUs that have their own
Ethernet interface can be connected directly with an ES523.1 module and com-
municate with INCA via Ethernet.
The ES523.1 has four ECU interface CAN FD. Two of the four CAN interfaces
additionally offer a "Wake-Up" function.
If necessary, systems can be cascaded using ES59x nodes. The Ethernet
switch guarantees the time-synchronous sampling of all measurement chan-
nels – even in sizeable module networks.
The ES523.1 module and the relevant cables are intended for use in the lab, on
the test bench and in the passenger cell of vehicles.

5 Functional Description
This chapter describes the block diagram, power supply, Ethernet switch, mod-
ule network, time synchronization, ECU interfaces and the firmware update.
5.1 Block Diagram
Fig. 5-1Block Diagram
To fulfill the operation demands in the vehicle, the interfaces of the ES523.1 are
each routed to an Lemo socket.
5.2 Power Supply (7-29V DC)
The power supply interface (7-29V DC) is routed to a 2-pin connector (Lemo
socket) on the back panel of the module. Power is supplied to the module via
an external power supply or vehicle battery.
When the ES523.1 is connected to the operating voltage and there is an Ether-
net connection at HOST, the module boots. If there is no Ethernet connection,
the module changes to “Standby.”
5.3 Ethernet Switch
The integrated Ethernet switch is used for the connection of the ES523.1 mod-
ule and other measurement or interface modules to a user PC. Data from the
connected modules is acquired synchronously (ETAS device synchronization,
see chapter 5.5 on page 23). The Ethernet switch can be cascaded with other
network modules so that you can create larger blocks of measurement and
interface modules.
NOTE
The ES523.1 must be physically disconnected from all supply voltages so the
module is not supplied with power.
