Which of the following is a military standard data bus?
Mil Std 1553
Which one of the following is a military standard data bus? Explanation: Mil Std 1553 is a US military standard data bus which came out in the 1970s in the F-16 and the following models of fighter aircraft.
Does MIL-STD-1553B Specify the length of the bus?
MIL-STD-1553B does not specify maximum bus length or maximum stub length. Only a suggested maximum stub length is given.
What is the difference between 1553A and 1553B?
The basic difference between the 1553A and 1553B revisions is that in the latter, the options are defined rather than being left for the user to define as required. The primary goal of the 1553B was to provide flexibility without creating new designs for each new user.
Why buses are multiplexed?
The major reason of multiplexing address and data bus is to reduce the number of pins for address and data and dedicate those pins for other several functions of microprocessor.
How are FBW signals transmitted?
Explanation: In an FBW system, the electronic signals are transmitted using wires. The movements of flight controls are first converted to electronic signals and then transmitted.
What type of cable is used in Arinc 629?
The ARINC 629 data bus cable consists of an unshielded twisted pair of wires. The wires are #20 AWG and are bonded together continuously along their length.
What is a 1553 bus?
MIL-STD-1553 Bus Description MIL-STD-1553 is a DOD Military (MIL) Standard (STD), which defines both the Mechanical, Electrical, and Functional characteristics. MIL 1553 uses a Balanced (Differential) interface. The interface is dual redundant with between 2 and 32 interface devices on the bus.
What is the 1553B spec?
The 1553B spec dictates that all devices in the system be connected to a redundant pair of buses to provide an alternate data path in the event of damage or failure of the primary bus. Bus messages only travel on one bus at a time, determined by the Bus Controller.
What is a MIL-STD-1553 multiplex data bus system?
A MIL-STD-1553 multiplex data bus system consists of a Bus Controller (BC) controlling multiple Remote Terminals (RT) all connected together by a data bus providing a single data path between the Bus Controller and all the associated Remote Terminals.
How are subsystems and 1553 bus elements interfaced with each other?
Subsystems and 1553 bus elements are interfaced to the main data bus by interconnection buses (called “stubs”). These stubs are either connected directly to the main bus or interfaced via data bus couplers.
