Scope of delivery

Field of use

Signal converter from RS 485 to RS 232. This is used to connect a device with an RS 232 interface to
another device with an RS 485 interface.

Use

The converter is intended for the following device combinations. The DIP switch must be set according
to the combination (see also "Configuration").

For SK 180E ... SK 5xxE series devices, no converter is required for communication with a PC, as the
devices are also equipped with an RS 232 interface. The converter only needs to be connected in
case one or more devices are to be connected to the PC via an RS 485 interface.

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.

Connections

The converter is connected between e.g. the motor starter and the ParameterBox (see below).
