13.12.1
The MIL-STD-1553
The MIL-STD-1553 specification defines the characteristics of a serial data bus origi-
nally designed for use in the military avionics. Nowadays it is also used in spacecraft
on-board data handling.
The bus is a 2-wire bus that uses differential signals.
A MIL-STD-1553 system consists of the following components:
●
Bus Controller (BC): initiates and coordinates the data flow in the system.
●
Remote Terminal (RT): interfaces various subsystems with the data bus. A system
consists of up to 31 RTs and each RT can have 31 subaddresses.
The subaddresses 0 and 31 refer to a mode code command.
●
Bus Monitor (BM) (optional): listens to all messages and can record selected data
for real-time or off-line analysis.
The information is transmitted over the bus in defined series of words using Manches-
ter code, where each bit is transmitted as high-low for a logical 1 or a low-high for a
logical 0. There are three types of words: command, data and status.
