Abstract
A remotely-accessible electronic circuit is provided, which, in wireless communication with a maritime pilot's Personal Pilot Unit (PPU), or other remote computer, is able to identify a common mis-wiring of an Automatic Identification System (AIS) Pilot Port in a maritime vessel. The circuit then is remotely controlled to electronically manipulate the connections that provide raw transmit and receive signals from the AIS Pilot Port. The electronic manipulation corrects the common mis-wiring without actual physical intervention of the pilot with the AIS Pilot Port, or other mechanical interface between that port and the pilot's PPU.
Claims21
A method for remotely monitoring and modifying a signal in a radio interface, comprising:
- monitoring raw transmit and receive signals with a circuit;
- converting the raw transmit and receive signals to transistor-transistor logic (TTL) level signals in the circuit;
- processing the TTL level signals to isolate the TTL level signal representing the raw transmit signal from the TTL level signal representing the raw receive signal;
- electronically manipulating the respective isolated TTL level signals to ensure that a correct one of a transmit or receive TTL level signal is presented;
- monitoring an output TTL level signal from the circuit to determine whether the output TTL level signal is in an inverted or non-inverted state;
- and
- when the monitoring determines that the output TTL level signal is in an inverted state, electronically manipulating the output TTL level signal in the circuit to re-invert the output TTL level signal,
- wherein a remote computer in wireless communication with the circuit automatically executes at least the monitoring the output TTL level signal and the electronically manipulating the output TTL level signal.
A circuit for remotely monitoring and modifying a signal in a radio interface, comprising:
- inputs that input raw transmit and receive signals into the circuit;
- transistor-transistor logic (TTL) gates that convert the raw transmit and receive signals to TTL level signals;
- a first exclusive OR gate to which a TTL level signal representing the raw transmit signal and a TTL level signal representing the raw receive signal are fed;
- a second exclusive OR gate to which an output of the first exclusive OR gate is fed;
- and
- a control signal input via which a control signal is fed to the second exclusive OR gate,
- wherein an output TTL level signal from the second exclusive OR gate is monitored by a remote computer in wireless communication with the circuit to determine whether the output TTL level signal is in an inverted or non-inverted state;
- and
- when the remote computer determines that the output TTL level signal is in an inverted state, the remote computer asserts the control signal via the control line to the second exclusive OR gate to re-invert the output TTL level signal.
