A mount for devices used in a teleconferencing site is disclosed. The mount positions and secures the devices in a substantially linear array along a wall of the teleconference site. The mount provides both power and communication connections to the each of the devices. The preferred embodiment of the invention allows the devices to be secured and connected in a single mechanical motion. This is accomplished with an extrusion, which is preferably recessed within a channel shaped cavity within the wall of the teleconference site. The recessed cavity may be enclosed by a cover. A serial bus and distributed switching scheme allowing selective communication with each of the mounted devices are also disclosed.
