RS232/RS485
The service interface (Port C) can be converted into an RS232 or RS485 interface by modifying the setting of
the appropriate jumpers.
Jumpers X105 to X110 must be set to the same position!
The presetting of the jumpers corresponds to the configuration ordered.

With interface RS232 jumper X111 is needed to activate CTS which enables the communication with the
modem.
