Operating modes
The Simple Setpoint Box provides 3 operating modes:
485C (Control mode via RS485)
IO-C
(Control mode via IO communication)
IO-S
(Setpoint mode via IO communication)
Selection of the operating mode is performed automatically by the box. However, with versions with firmware
version V1.2 or higher and from week of manufacture 20L (Week 20 2011) it can be pre-set via 2 DIP switches.

If the DIP switches are configured to Auto Scan and no participant is detected during the scanning process, the box
automatically changes to the operating mode IO-S.
If the operating mode was pre-set to 485C or IO-C via the DIP switches and a suitable connection to the frequency
inverter can be established, the Simple Setpoint Box goes into Fault mode after a short time (Error E009).
Information
Firmware version
The version number of the SK SSX-3A firmware is displayed by holding the OK key pressed when the box is
switched on (Power UP).
3.1.3.1 Operating mode 485C (Control mode via RS485)
With the 485C operating mode, communication with the connected frequency inverter is carried out via the RS485
interfaces of the Simple Setpoint Box. Here, all the features provided by the SimpleBox SK CSX-3H/ -3E (Section
2.2) are also available.
Field of use
In this operating mode, the box can communicate with the series SK 2xxE, SK 300E, SK 5xxE, SK 700E and SK
750E. The prerequisite for this is that the relevant frequency inverters are equipped with a suitable interface
(RS485) (on the terminal bar or RJ 12 socket.
