Abstract: A Keyboard, Video, Mouse (KVM) switch that includes one or more input ports to receive events, notifications and/or alarms generated by an external device. The KVM switch receives the events, notification and/or alarms in the form of an external signal. The KVM switch processes the external signals and compares the received external signal to one or more reference signals to identify an event that corresponds to the received external signal. The KVM switch then generates an announcement for display on one or more displays associated at least one user station coupled to the KVM switch.
