synchronization, see section 3.8 on page 26). The Ethernet switch can be cas-
caded with other network modules so that you can create larger blocks of
measurement and interface modules.
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 switchover takes place automatically.
To fulfill the operation demands in the vehicle, the “HOST”, “ETH1”, “ETH2”
and “ETH3” interfaces of the ES511.1 are each routed to an 8-pin port (Neu-
trik ports). Sturdy Ethernet cables with Neutrik connectors (see section 6.2
on page 48) can be connected to the interfaces of the ES510.1 Network Mod-
ule.
All switch interfaces are galvanically isolated from each other and from the
power supply.
3.3.1 “HOST” Port
The upstream Ethernet interface “HOST” combines the ES511.1 module with
the user PC or a further module of the ES51x line. This interface allows the
ETAS software tools access to the connected modules.
3.3.2 “ETH1”, “ETH2”, “ETH3” Port
The downstream Ethernet interfaces “ETH1”, “ETH2” and “ETH3” connect
the ES511.1 module to other ES51x modules, measurement, calibration and
rapid prototyping modules. A list of compatible modules can be found in sec-
tion on page 40.
Note
The ES511.1 cannot supply power to connected ES51x modules or modules
of other lines. Every connected module must be wired separately to the
power supply.
Note
You can also use Ethernet patch cables (1:1, twisted pair, Cat5) in limited
environmental conditions (e.g. in the lab).
Note
ES600 network modules can only be connected to the “ETH1”, “ETH2” and
“ETH3” interfaces at the ES511.1 module.
