Scalance X101-1Aui Aui Interface - Siemens SCALANCE X101-1AUI Commissioning Manual

MDI /MDIX Autocrossover Function
The advantage of the MDI /MDIX autocrossover function is that straight-through cables can
be used throughout and crossover Ethernet cables are unnecessary. This prevents
malfunctions resulting from mismatching send and receive wires. This makes installation
much easier for the user.
All devices of the SCALANCE X-101 product line support the MDI / MDIX autocrossover
function.
Note
Autopolarity is not supported.
