2.3 Serial Interfaces
The PKV 30-COS possesses two independent interfaces.
First Serial Interface (X3).
The first interface cab be selected to operate as a
communication RS232C-, RS422-, or RS485 interface or as a diagnosis / configu-
ration interface. The setting of the communication interface takes place over
plug-in jumpers at J5 (see also chapter “Configuration”).
Second Serial Interface (X2).
The second serial interface is designed for opera-
tion at the CANopen.
2.3.1 First non-floating interface (X3)
This interface with a 9 pole D-Sub plug to DIN 41652 serves for connecting a de-
vice and can be configured as RS232-, RS422-, or RS485 interface. The setting
takes place over plug-in jumpers at J5 (see also “Configuration”).
In the same way a diagnosis/configuration of the device is possible. The activati-
on of the diagnosis/configuration operation is described in the chapter “Acti-
vating the Diagnostic/Configuration Operation” in this manual.
