3.5 Configuration
The field multiplexer does not require any configuration software. It is configured with cable
jumpers on the connectors.
3.5.1 Configuring the "fiber optics (FO)" transmission mode
If you want to implement fiber optic data transmission, insert a cable jumper at connector 1
from 1.1 to 2.1 (CONF
FO
) (see Figure 3-6 on page 22).
Set the required fiber optic converters to a transmission rate of 75 kbaud and a character
length of 11 bits (see also Section “Transmission over fiber optics” on page 68).
3.5.2 Configuring the station as a master or a slave
One field multiplexer station must be configured as the master. To do this, insert a cable
jumper at connector 3 from 1.4 to 2.4 (CONF
MA
) (see Figure 3-6 on page 22).
The second station must be configured as a slave. It must not have a wire jumper at
connector 3 from 1.4 to 2.4.

ACHTUNG: Malfunction
Ensure that the same transmission mode (copper/fiber optics) is always set on the field
multiplexer station and the opposite station.
