Configuration
Configuration of the converter is restricted to a DIP switch on
the front side of the converter. This determines the interface
on which the master is located.
No communication is possible if the DIP switch is not
set correctly.
ATTENTION Possible damage to devices
Care must be taken that only one participant takes on the master function. Failure to observe this may cause
damage to the relevant drivers.
