12.5 Automotive Ethernet Interface (AE)
100BASE-T1 Automotive Ethernet interfaces are available at the AE connection of
ES800 modules:
- ES882.x: Three Automotive Ethernet interfaces
- ES886.x: Four Automotive Ethernet interfaces
The 100BASE-T1 Automotive Ethernet interface is based on the BroadR-Reach
technology developed by the OPEN Alliance Special Interest Group and has been
standardized by the IEEE working group 802.3bw. When using Automotive Ether
-
net, communication is carried out with a full duplex system via a cost-effective
twisted two-wire cable.
ECUs that are equipped with a BR_XETK or have a separate Automotive Ethernet
interface can be directly connected and can communicate with the application
software via XCP-on-Ethernet at the Automotive Ethernet interface (AE) of the
module.
A media converter between the 100BASE-T1 Automotive Ethernet and the IEEE
802.3 Standard Ethernet is not required when using the ES800 module with an
Automotive Ethernet interface (AE).
12.5.1 Display of the functional Status of the AE Interface
ES882.x
The three Automotive Ethernet interfaces AE1, AE2 and AE3 of the ES882.x module
are assigned to the LEDs 1, 2 and 3 respectively.
WARNING
Risk due to undefined system behavior when disconnecting the transparent
automotive Ethernet communication between ES886.1/ES886.2 and the ECU
The ES886.1/ES886.2 must not be disconnected from the operating voltage
during an active transparent automotive Ethernet connection.
NOTE
See chapter “Requirements for failsafe Automotive Ethernet Operation” on
page 129 for details on wiring the Automotive Ethernet interface cables.
