NOTICE 

Damage to the electronics due to potential equalization

The cables' shield may be connected to the housing, the ground or the ground for the product's power supply. If there are different ground potentials in the test setup, equalizing currents can flow between the products via the cables' shield.
Take account of different electric potentials in your test setup and take appropriate measures to prevent equalizing currents.

Note  

Ensure that the test setup is EMC-compliant. A test setup that uses shielded and unshielded components at the same time can lead to impairment of the signal quality and is not recommended by ETAS.

Note  

Please ensure that the device is installed and operated as described in the user manual to maintain the specified EMC properties in the respective application. Deviation from the specified installation and operation instructions or connecting the device with other devices may result in a deviation from the specified EMC properties.

The ES165.1 is designed to connect to an Automotive Ethernet Network, a PC and an external power supply.

Failsafe automotive ethernet operation

For failsafe operation of the automotive ethernet communication channel, all customer specific installations - including cables, connectors and board adaptations - have be compliant to:

  • IEEE Std. 802.3bwTM-2015, “Amendment 1: Physical Layer Specifications and Management Parameters for 100 Mb/s Operation over a Single Balanced Twisted Pair Cable (100BASE-T1)”, chapters 96.7 - 96.9
  • Open Alliance, “BroadR-Reach® Definitions for Communication Channel, Version 2.0”

Note  

To achieve an appropriate Automotive Ethernet channel performance all PCB board and cable segments have to be optimized with regard to line impedance matching, length matching within the differential net routing or twisted pair cabling and on the reduction of untwisted regions. Stub segments must be avoided for the Point-to-Point cable connection in favor of inline connectors and shielding measures shall be considered depending on the operation environment.

Note  

Please contact your ETAS partner if you need to use Automotive Ethernet cables in areas with severe interference.
