2.2 About the Base Unit
Base Unit functionality
The Base Unit receives the wireless input from the Buttons and controls the content of the meeting room
display and the peripherals connected to the Base Unit (speakers, microphones, webcam and soundbar).
Furthermore, it will send out the content from the camera and/or the echo-cancelling speakerphone towards
the Button.
The Base Unit can be put on the meeting room table or mounted on a wall or ceiling. Check the installation
guide for instructions on how to install the Base Unit.

USB ports
Both USB ports, one USB Type-C
TM
and one USB Type-A, are used to connect a USB camera or USB echo-
cancelling speakerphone to the Base Unit. Additionally the USB Type-C
TM
port is also used to pair the Buttons
when not done via XMS. Both ports can be used to update the Base Unit firmware also when not done via
XMS..
When plugging in the Button into the Base Unit, the Button is paired to the Base Unit. The Base Unit checks
whether the software and firmware of the Button is up to date. If not, the Base Unit updates the software and/
or firmware.
The use of a convertor is sometimes necessary to connect to one of these ports.
Status LED ring
The color of the LED ring around the power button of the Base Unit give information on the status of the
system.
