5.3.10 Plug in of the Profibus SAB Cabs
Attention!
Before plugging the Profibus SAB cabs to the connectors of the reader, make sure that the ground-
ing of the device is well done. Otherwise the electronic may be destroyed by electrostatic discharge.
6 Definition of the Profibus Slave Attributes
Before bringing the ARE K1 / PFB into operation in the Profibus net, the adress of the slave has to be
adjusted. If the reader is used at the end of a line, then the termination switch has to be set into the
"On" position in addition.
All control elements for the definition of the Profibus atributes are displayed in the figure below. Due
to the fact that all control elements are placed in the SAB ports they are accessible without opening
the housing.

The switch for activation the termination is situated in the left Profibus port. The positions for the
"On" and "Off" states are marked on the on the surface of the printed circuit board (PCB).
Attention!
Make shure, that only one device inside of a network line is terminated.
The switches to adjust the node adress are placed in the right Profibus port. The quality rating of the
singgle switches ( X1 resp. X10 ) are marked on the surface of the PCB. To make operative a new
adress node adjustmant it is essential to reset the ARE K1/PFB. This can be done very easily by short-
time breaking of the power supply.
