Remote Control Bus Hub
The Remote Control Bus Hub provides eight parallel ports for the connection of remote control
devices to an Audia® system. Each port can accept multiple remote controls connected in a 5-
wire daisy-chain. A single Hub, connected to a single Audia unit, allows multiple branches to be
added to the remote control network. Also, maximum cable length is calculated only across the
two longest network branches, thereby effectively extending the network range. The Remote
Control Bus Hub can be used with any combination of control devices, including
Volume 8 , Select
8 , Volume/Select 8 , Logic Box , and Voltage Control Box .
Example Control Network

After initial programming & configuration, Audia® systems may be controlled by RS-232
communication from third-party control systems such as AMX® or Crestron®, using the Serial
Control Port. See
