A control system and method of selectively enabling an auto-shutoff feature of a control system for an aviation headset includes a power switch. The power switch is toggled and if the control system is in a powered down state, a startup sequence for the control system is initiated. During the startup sequence, a bias voltage detector checks for a bias voltage on a signal line of the headset. If a bias voltage is detected during the startup sequence, the auto-shutoff feature is enabled. The auto-shutoff feature periodically checks for a bias voltage and powers down the control system if no bias voltage is detected for a predetermined time interval. If no bias voltage is detected during startup, the auto-shutoff feature is disabled.

A method of managing communications between communication devices within a digital intercom system includes providing input and output tables for each communication device. The tables for each device are made up of cells formed from linear arrays corresponding to communication channels and the other devices. When two devices communicate on a given channel, a cell in the appropriate input and output table is identified based on the channel and the devices communicating. The cells provide volume control information which can be relied upon to determine if or to what degree audio signals should be transferred between the devices.

Method of controlling communications within a digital intercom system

A digital intercom system has first and second master stations. Each master station has hardware and software configured to allow duplex communication between a plurality of communication devices. The software is further configured to run a plurality of settings for directing communication between the communication devices of each master station. The master stations are configured to allow duplex communication between the devices of each master station. Inter-master channels define parameters for communication between the communication devices of each master station. The settings of the master stations can be modified based on input entered into a browser based program run on a first input/output device by a user.

Digital intercom system having multiple master stations

A digital intercom system has a master station with hardware and software configured to allow duplex communication between a plurality of communication devices. The software is configured to run a plurality of settings for directing communication between the communication devices, the settings including a plurality of channels for each communication device. The channels each define parameters for how the communication devices within the system will communicate. An audio output device is linked to a corresponding communication device of the plurality of communication devices such that the audio output device is configured to receive and play the same audio as the corresponding communication device. The master station is configured to modify the settings based on input entered into a browser based program run on an input/output (I/O) device by a user.
