2.1.5 Setting of the communication bus, RS232 PC serial and central unit
language
The series of SD2 dip-switches are used to set the following:
• Baud Rate (communication speed) and RS485 bus protocol with field devices
(detectors and IN/OUT modules).
• Baud Rate (speed) of communication of the RS232 serial port to the personal
computer
The series of SD3 dip switches is used to set the language of text on the display of the
central unit.
