Connecting the Bridge

The Bridge and other Adamson devices can be connected to the AI software using standard ethernet ca-
bling (minimum Cat5e). If the network is used for control only, standard gigabit switches can be used in
addition to the switch-ports of the Bridge. A maximum of eight devices can be connected in a daisy-chain.

AVB Milan Audio

Full network connectivity, including AVB audio transport and control requires AVB enabled switches. Cur-

work with Adamson AVB systems. As the Bridge includes a Milan enabled switch it can be used for smaller
AVB Milan setups without additional switches.
