7.6.4 Parameters for parallel Operation of redundant CPU Units
CPU Units with a redundant port 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.
To configure a redundant CPU Unit for the operation with two parallelly controlling CON Units, proceed as follows:
1. Connect a redundant CPU Unit to any source by using a Mini-USB connection.
The extender module opens a flash drive containing the
Config.txt
file.
2. Open the
Config.txt
file in a text editor.
3. Ensure that
#CFG
is in the first line of the file.
4. 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.
5. Delete everything that follows the entered parameter/s.
6. Save the
Config.txt
file.
7. Manually power off the extender module.
8. Power on the extender module to restart the extender module.
The extender module starts automatically, and the extender module parameters will be rewritten in the
Config.txt
file.

NOTICE
When using the redundant CPU Unit in combination with a KVM matrix, the function of competing control will be
automatically deactivated in the extender module and will have to be configured by the KVM matrix.
