Note: An integrated field device EOL resistor 100 Ω + 1 mF (IEC 61158-2) is
fitted in the field device coupler.
By inserting a jumper between the TERM 1 and 2 terminals, the fieldbus
EOL resistor is connected to the trunk.
As an alternative, it is also possible to use a Series 9418 external fieldbus
EOL resistor at the Trunk OUT connection.
