The UE2120H allows users to extend the distance between a computer and USB device(s) up to 12 meters via the active extender hub. USB signals transmitted through these cables maintain optimal signal integrity and meet USB 2.0 standards. Up to 4 extender cables (UE2120) and 1 Extender Hub (UE2120H) can be chained together, so that cable distance is increased by up to 60 meters.
