3.8.2  Ethernet cables and connectors 
Characteristics of the cables 
A shielded twisted pair cable is used for the networking.  
The transmission rate of the cable is determined as follows by the number of core pairs: 
●  2 x 2 cores support 10/100 Mbit/s 
●  4 x 2 cores support 10/100/1000 Mbit/s 
Recommended connecting cables 
The following cables are available: 
●  SIMATIC NET, Industrial Ethernet TP XP CORD RJ45/RJ45 
–  TP cable prefabricated with 2xRJ45 connectors 
–  Crossed send and receive cable 
–  Order no.: 6XV1870-3R ( - length code) 
●  SIMATIC NET, Industrial Ethernet TP CORD RJ45/RJ45 
–  TP cable prefabricated with 2xRJ45 connectors 
–  Uncrossed send and receive cable 
–  Order no.: 6XV1870-3Q ( - length code) 
The autocrossing functionality of the Ethernet interfaces means crossed as well as 
uncrossed cables can be used. 
Autocrossing 
Per default, the Ethernet interfaces are set to "Automatic setting" in HW Config, so that 
autocrossing is available. 
The settings can be found in the port properties (e.g. X127 P1) in the module rack of HW 
Config (SIMOTION < V4.3: Setting via HW Config "D4x5-2 Properties" > "Ethernet 
extended"). 
Autocrossing is deactivated with "Manual setting". As the Ethernet interfaces of the D4x5-2 
are wired as Ethernet terminal, in this case you must use crossed cables for the networking 
with a PG/PC or another D4x5-2.  
If the communication peer has autocrossing (e.g. PC, switch or hub), crossed and uncrossed 
cables can be used.
