6.3 Shared Operation
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.
2017-03-31 37
Draco CPU Switch
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.
Example View – Config.txt
When using redundant CPU Units in combination with a KVM matrix, the function of competing control will be automatically deactivated in the extender and will have to be performed by the KVM matrix.

7.1.4 Analog Audio Interface
The analog audio option supports a bidirectional stereo audio transmission, in nearly CD quality .
The audio interface is a 'line level' interface and it is designed to transmit the signals of a sound card (or another 'line level' device) as well as to allow the connection of active speakers to the CON Unit.
Stereo audio can be transmitted bidirectionally at the same time.
Connection of a microphone:
Connect the microphone to the 'audio' input of the CON Unit. There are two ways to establish this connection:
The output of the CPU Unit is connected with the microphone input of the sound card (red). Adjust the sound card to provide an additional amplification (20 dB).
The output of the CPU Unit is connected to the audio input of the sound card (blue). Choose this connection if the microphone has its own pre-amplifier.
The CON Unit can do the pre-amplification of the microphone as well.
Open the CON Unit, locate the 'MIC' jumper on the audio board and close the pins.
