Figure 19: Pin assignment of a TP/TX interface in MDI-X mode, RJ45 socket
10/100/1000 Mbit/s twisted pair connection
1000 Mbit/s twisted pair ports (RJ45 sockets) facilitate the connection of
terminal devices or independent network segments according to the IEEE
802.3-2000 (ISO/IEC 8802-3:2000) 1000BASE-TX standard.
These ports support:
Autonegotiation
Autopolarity
Autocrossing (if autonegotiation is activated)
1000 Mbit/s full duplex
100 Mbit/s half duplex, 100 Mbit/s full duplex,
10 Mbit/s half duplex, 10 Mbit/s full duplex.
Default settings: autonegotiation.
The socket housing is electrically connected to the front panel.
The pin assignment corresponds to MDI-X.

Note: In general, you should adhere to the following recommendations for
data cable connections using copper in environments with high electrical
interference levels:
Keep the length of the data cables as short as possible - ideally max.
3m long. You should not use any copper data cables for the data trans-
mission between buildings.
