6.2 Shared Operation of redundant CPU Units
CPU Units with a redundant connector for interconnect cables offer the
possibility for a competing control by two connected CON Units.
Taking over control is performed using a keyboard and/or mouse. The
release timer function determines the release time of the input devices at
one of the CON Units after that control can be taken over from the second
CON Unit.
In order to configure a redundant CPU Unit for the operation with two
competing CON Units, proceed as follows:
1. Connect a redundant CPU Unit to any source (computer, CPU) by
using a mini USB connection.
2. Open the file "Config.txt" that is located on the appearing flash drive
of the extender.
3. Activate the release timer by writing the parameter
RELEASETIME=n
into the second line. The variable "n" defines the time in seconds and
has to be replaced by the numbers 0 to 9 (e.g. RELEASETIME=5).
If this parameter is not activated at all, the release time is set to
2 seconds by default.
The parameter
RELEASETIME=X
deactivates the shared operation.
4. Save your changes.
5. Reboot the CPU Unit.
