Specified Cables The cables are specified by category depending on their transmission and high-
frequency properties as follows:
The channel as a point-to-point transmission path is defined as follows:
The higher the letter, the greater the demand on the transmission channel. For
Ethernet communication at 100 MHz, Category 5 (or higher) cables and at least
Class D capacity are required.
RJ45 Connector For direct Ethernet plug connections without interface elements, you can use
connectors such as IP 20 Data Plug (Harting
(R)
). You can assemble the cable
quickly by crimping the conductors; special tools are not required.
Switches To span distances of more than 100 m (328.1 ft) using SafeEthernet protocol, rail
switches of the RS2 series (Hirschmann
(R)
) with optical fibre ports are
recommended.
