Equipment Description

Specified Cables The cables are specified by category depending on their transmission and high- frequency properties as follows:

Category

Approved

 

 

 

1

No

 

 

 

2

up to 1 MHz

No

 

 

 

3

up to 16 MHz

No

 

 

 

4

up to 20 MHz

No

 

 

 

5

up to 100 MHz

Yes

 

 

 

6

up to 250 MHz

Yes

 

 

 

7

up to 600 MHz

Yes

 

 

 

The channel as a point-to-point transmission path is defined as follows:

Class

Specification

Approved

 

 

 

A

up to 0.1 MHz

No

 

 

 

B

up to 1 MHz

No

 

 

 

C

up to 16 MHz

No

 

 

 

D

up to 100 MHz

Yes

 

 

 

E

up to 250 MHz

Yes

 

 

 

F

up to 600 MHz

Yes

 

 

 

 

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.
