Glossary

1553 or 1553B Databus	The MIL-STD-1553B databus is a military standard communications system that allows the transfer of data between units coupled on a shared communications path(databus). The systems on the bus can be electrically isolated. The bus runs at 1Mbps and utilises a 16 bit word, although a total of 20 bits are utilised to perform error checking. The system is controlled by a box called the Bus Controller of which there must always be one. The bus controller can communicate with a maximum of 31 units on the bus.
