MIL-STD-1553 is the military's equivalent to ARINC-429, though structurally it is very different. The first and most obvious difference is that 1553 links are typically designed with dual, redundant channels. … Also, a MIL-1553 device can serve as Bus Controller, Bus Monitor, or Remote Terminal.
CAN bus vs MIL-STD-1553?
What is a 1553 bus?
MIL-STD-1553 is a military standard that defines mechanical, electrical, and operating characteristics of a serial data communication bus for the U.S. Department of Defense. It is now commonly used for both military and civilian applications in avionics, aircraft, and spacecraft data handling.
What is the maximum useable bus throughput for MIL-STD-1553?
200 Mbits/s Mil-Std-1553C Known as Mil-Std-1553B, Notice 5, the specification increases the throughput capacity of the 1553 bus to an uncompressed data rate of 200 Mbits/s over existing aircraft wiring, while maintaining a 10 -12 bit error ratio.
What describes best the role of the bus controller on a MIL-STD-1553 network?
Bus protocol. 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 does a 1553 bus work?

What is a 1553 frame?
A minor frame is a set of 1553 messages. … When you create a minor frame, each message in the frame points to the next message. The last message in a minor frame points to the first message in the next minor frame. The last message in the last minor frame points to the first message in the first minor frame.
What is a 1553 subaddress?
1553 is a one mega bit bus so each word takes 20 µSecs of transmission time. A “Command Word” is the first word of every message sent by the BC: this word commands the RT to receive or transmit at a given “Subaddress” with a set number of “Data Words” transferred between the computers.
What is bus controller?
SM Bus Controller or System Management Controller is a Chipset on the Motherboard. Its main purpose is to monitor the board's voltage and temperature.
How does a data bus coupler work?
Data Bus coupler is a device which is used to couple one bus to the other without any interruption in power supply and without creating hazardous arcs. Bus coupler is a breaker used to couple two bus bars in order to perform maintenance on other circuit breakers associated with that bus bar.
