2.2.4 RS-232 interface for external management
The 6-pos. Mini-DIN socket provides a serial interface to connect a local management sta-
tion. It enables the connection to the management interface (for an appropriate cable,
please refer to page 170) via a VT100 terminal or a PC with corresponding terminal emula-
tion. Set the following transmission parameters:

2.3 Grounding
All Factoryline devices must be grounded so that any possible interference is shielded from
the data telegram and discharged to ground potential.
A wire of at least 2.5 mm
2
must be used for grounding. When mounting on a DIN rail, the
DIN rail must be connected to protective earth ground via grounding terminal blocks. The
module is connected to protective earth ground via the metal header.

Grounding protects people and machines against hazardous voltages. To avoid these
dangers, as far as possible, correct grounding, taking the local conditions into account, is
vital.
