Application Note for TesiraFORTÉ TeamConnect Ceiling 2 HID Communication Logic The EX-UBT synchronizes privacy mute state and volume control when connected to the Microsoft Teams Room System. This is achieved through Human Interface Device (HID) communication. Within the running Tesira configuration, room level control from the Teams Room System user interface will sync with the level control in the EX-UBT USB Input block, while privacy mute from the Teams Room System user interface will sync with the mute control in the EX-UBT USB Output block. By default, the Microsoft Teams Room System volume control will set to 50 when a meeting is started. This level will be reflected in the EX-UBT USB Input block as shown on the image to the right. The TeamConnect Ceiling 2 can be controlled by a 3rd party device over UDP port 45. This is accomplished in Tesira by using a Network Command String block and requires that the Tesira control port be connected to the same network as the TCC2 PoE/Ctrl port. The IP address assigned to the TCC2 PoE/Ctrl port is entered in the Server Address field. HID mute sync feedback from the Teams Room System is used to set the LED color on the TCC2, Red for privacy "mute on" and Green for privacy "mute off". This also triggers a Mute block to mute and unmute the audio being sent to the far end participants. When configuring the TCC2 from Control Cockpit, be sure to set the Custom Color to Red and leave the mic unmuted. Privacy mute will be handled in Tesira, post AEC processing. AN 1255 v1.0 | 7/11
