7.2.1.1 Pin Assignment
Fig. 7-16: 9-pin D-SUB male and female connector strip
Connector in the small operator terminal: 9-pin D-SUB male and
female connector strip (assignment for male and female connector strip
is the same).
All signal lines are looped through from X2.1 to X2.2. The connecting
cables should be connected to every pin, including the reserved pins.
In this way, the cables can still be used in case of future bus specifica-
tion extensions.

The D-SUB connector strips must be shielded sufficiently. See chapter
„Shielding D-SUB Connectors“ on page 7-23.
A DeviceNet-certified cable must be used.
