The R485 interface can be converted into an RS232 interface by modifying the jumpers.
Jumpers X105 to X110 must be set to the same position !

The jumpers are preset at the factory according to the configuration ordered.
With interface RS232 jumper X111 is needed to activate CTS which enables the communication with the
modem.

Jumper setting 2-3: The connection to the modem is usually established with a star coupler or fibre-optic
converter. Therefore the modem control signals according to RS232 standard DIN 66020 are not available.
Modem signals are not required since the connection to the SIPROTEC? 4 devices is always operated in the
half-duplex mode. Please use the connection cable with order number 7XV5100-4.
Jumper setting 1-2:This setting makes the modem signals available, i. e. for a direct RS232-connection
between the SIPROTEC 4 device and the modem this setting can be selected optionally. We recommend use
of a standard RS232 modem connection cable (converter 9-pole on 25-pole).
