Abstract: A system for, and method of, operating an ARINC-429 transmitter by receiving a signal sequence from a transmission unit and converting the signal sequence into a differential output signal for outputting to a receiver. The transmission unit generates a signal sequence for the ARINC-429 transmitter. The ARINC-429 transmitter is configured to transmit an output signal at a high or a low transmission rate to the receiver depending on a received signal sequence from the transmission unit. The data transmission rate at the low transmission rate can be in the range of 12-14.5 kb/s±1% and the data transmission rate at the high transmission rate can be 100 kb/s±1%.

Abstract: A non-volatile 1-bit state storage including a first signal converter for converting a digital input signal into an analog intermediate signal and a second signal converter for converting the analog intermediate signal into a digital output signal. The first signal converter is provided with a non-volatile memory so that after an outage of a power supply voltage, the previously output analogue intermediate signal is restored. A bistable solid-state relay that assumes a bistable switching state by means of the non-volatile 1-bit state storage and restores this state after an outage of the power supply voltage.
