  • System having termination for data loading port
    Patent number: 7564371
    Abstract: A subsystem of an avionics system is operated in a first mode for receiving software via a port; and in a second mode in accordance with a circuit that includes a terminator coupled to the port. By using the terminator to convey information regarding a desired configuration for operation in the second mode, communication and wiring is avoided between subsystems of the avionics system for conveying such information. In one implementation, operation in the second mode includes performing a collision avoidance function (e.g., providing a TCAS advisory). Configuration information in accordance with the circuit may specify an arrangement of shared antennas between multiple transponders and/or mode changes related to using an antenna for a collision avoidance function in a hijack mode of operation.
