ETAS ES523.1, User Manual, Page: 21 / 67

ETAS Functional Description
ES523.1 - User Guide 21
The switch is equipped with Ethernet interfaces in accordance with the stan -
dard 10/100BaseT that can be operated with either 10 or 100 Mbit/s, half or full
duplex. The switch over takes place automatically.
All switch interfaces are galvanically isolated from each other and from the
power supply.
5.3.1 Host Port (HOST)
The upstream Ethernet interface HOST combines the ES523.1 module with the
user PC or with a downstream Ethernet interface of a further module. This inter
-
face allows the ETAS software tools access to the connected modules.
"Wake-Up" Function
The Ethernet interface HOST supports the "Wake-Up" function (see chapter 5.6
on
page 23).
Compatible Modules
A list of compatible modules can be found in chapter 8.10.2 on page 46.
5.3.2 Ethernet Ports (ETH1, ETH2 and ETH3)
The ES523.1 module provides three downstream Ethernet interfaces for further
modules. ECUs that have an XETK or their own Ethernet interface can be con
-
nected directly with a ES523.1 module and communicate with the calibration
software via XCP-on-Ethernet.
Module Network
The downstream Ethernet interfaces ETH1, ETH2 and ETH3 connect the
ES523.1 module to other ES600 modules, measurement, calibration and rapid
prototyping modules. Large blocks of measurement and interfaces modules
can be created as the modules can be cascaded.
Power Supply of connected Modules
The ES523.1 module can additionally power ES4xx modules, ES6xx modules or
XETKs via the Ethernet connection cable. Take a note of the maximum output
current at the Ethernet ports when the modules are cascaded.
Other modules connected via Ethernet cable must be wired separately to the
power supply.
"Wake-Up" Function
The Ethernet interfaces ETH1, ETH2 and ETH3 support the "Wake-Up" function
(see chapter 5.6 on
page 23).
Compatible Modules
A list of compatible modules can be found in chapter 8.10.3 on page 47.
