Jumper settings
There are nine jumpers in jumper header X10. The signal cables from the printed circuit board are
connected to the interface connector via these jumpers.
The 20 mA current supply of the active TTY interface is switched on with jumpers 1 and 2.
Jumpers 3 to 8 connect the signal cables of the RS-232-C (V.24) interface to the interface
connector. Jumper 9 connects the ground with the interface connector.
Note
Note the different safety characteristics of the TTY and RS-232-C (V.24) interfaces.
The current-driven TTY interface contains an optocoupler which guarantees reliable
galvanic isolation between the 220 V supply of the operator panel and the CP 523.
The voltage-driven RS-232-C (V.24) interface contains
no such galvanic isolation.
