U.motion KNX Server Plus, Touch
Installation Manual
Due to the different audio levels, which can occur when using different VoIP devices for communication, these values are
only temporary adjustments that are lost when restarting the device. In the configuration area of the respective U.motion
KNX Server Plus Touch, also default values for the speaker volume and the sensitivity of the microphone can be set and
stored permanently; U.motion KNX Server Plus Touch will load these values after every reboot as default values.
The corresponding settings are available under „TECHNOLOGIES->INTERCOM->SETTINGS“:
The adjustment of the audio settings is especially necessary when using door communication. The audio settings must be
adapted to fit with the installed door station. It is recommended to start with low volumes and then increase them
gradually until reaching an optimal voice quality. In addition, in this menu you can set the IP address of your VoIP server;
this setting called "PBX host address" is required only when an external VoIP server is used.
PBX-HOST-ADDRESS
IP address of the installed VoIP server. Normally U.motion KNX Server Plus Touch itself
is used as VoIP server („127.0.0.1“). If an external VoIP server is used (e.g. in condomin-
iums, apartment buildings), the IP address of the used VoIP server must be configured
here. U.motion KNX Server Plus Touch then communicates via this VoIP server with
the rest of the plant.
VOLUME MICROPHONE
Default setting for the microphones sensitivity in percent.
VOLUME LOUDSPEAKER
Default setting for the loudspeakers volume in percent.
ATTENTION: please note that in case of excessive sensitivity of the microphone and high volumes for the
loudspeaker, interruptions and echo can occur in the communication, since the built-in AEC (Acoustic Echo
Cancellation) cannot process distorted signals!
NOTE: the intercom volume control affects only ongoing voice communication (e.g. door communication).
Any acoustic signals, including the ringtone for intercom calls, are reproduced according to the configured
system volume, independently from the volumes configured in the intercom pop-up.
Further information about the configuration of the INTERCOM settings can be found in the appropriate manual of
U.motion KNX Server Plus Touch.
