ARINC 429 - Technical Description - Messages

Messages

ARINC 429 is a data transfer standard for aircraft avionics. It uses a self-clocking, self-synchronizing data bus protocol (Tx and Rx are on separate ports). The physical connection wires are twisted pairs carrying balanced differential signaling. Data words are 32 bits in length and most messages consist of a single data word. Messages are transmitted at either 12.5 or 100 kbit/s to other system elements that are monitoring the bus messages. The transmitter constantly transmits either 32-bit data words or the NULL state. A single wire pair is limited to one transmitter and no more than 20 receivers. The protocol allows for self-clocking at the receiver end, thus eliminating the need to transmit clocking data. ARINC 429 is an alternative to MIL-STD-1553.

Famous quotes containing the word messages:

    The first of the undecoded messages read: “Popeye sits in thunder,
    Unthought of. From that shoebox of an apartment,
    From livid curtain’s hue, a tangram emerges: a country.”
    John Ashbery (b. 1927)

    Acknowledging separation feelings directly and sympathetically is the best way of coping with them. It is actually helpful to tell a toddler “I’ll miss you,” or “I will think of you during the day,” or “It is hard to say goodbye,” or “I can’t wait to see you at the end of the day.” These messages tell the child that he is important to the parent even when they are not together and that out of sight need not mean out of mind.
    Alicia F. Lieberman (20th century)

    All the old supports going, gone, this man reaches out a hand to steady himself on a ledge of rough brick that is warm in the sun: his hand feeds him messages of solidity, but his mind messages of destruction, for this breathing substance, made of earth, will be a dance of atoms, he knows it, his intelligence tells him so: there will soon be war, he is in the middle of war, where he stands will be a waste, mounds of rubble, and this solid earthy substance will be a film of dust on ruins.
    Doris Lessing (b. 1919)
