V.24 (RS-232) interface for external management
The 6-pos. Mini-DIN female connector provides a serial interface to connect a local
management station. It can be used to connect a VT100 terminal or a PC with
corresponding terminal emulation to the management interface (for an appropriate cable,
please refer to page 12-9). Set the following transmission parameters:
Bits per second
38400
Data bits
8
Parity
None
Stop bits
1
Flow control
None

Grounding
All Factory Line 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 with protective earth ground using grounding terminal blocks. The
module is connected to protective earth ground via the metal base element.

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