13.7 MIL-1553 (option R&S RTP-K6)
13.7.1 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.
Command Word
Figure 13-10: Structure of a command word
The format of a command word consists of the following parts (see Figure 13-10):
●
Sync: an invalid Manchester waveform.
●
Remote Terminal (RT) Address: the unique address of the corresponding RT.
●
Transmit/Receive (T/R): indicates the action required from the RT.
●
Subaddress/Mode Code: indicates the RT subaddress. The subaddresses 0 and
31 signalize the transmission of a mode code.
