Connecting cables for connecting to Ethernet
There is no standard connecting cable available in the SINAUT range to connect the
TIM 4R-IE to Ethernet. Use the suitable Ethernet connecting cables (for example
IE TP Cord) from the SIMATIC NET product range (catalog IK PI).
If a TIM 4R IE is connected to a hub, switch or router, it is advisable to use fully shielded
straight-through patch cables with RJ-45 connectors and 1:1 pin assignment. The cable must
be suitable for the 10Base-TX or 100Base-TX specification.
Two Ethernet TIMs (TIM 4R-IE, TIM 3V-IE variant) can also be connected over Ethernet as a
point-to-point link using a crossover patch cable with RJ-45 connectors at both ends and the
following pinout:
