Three types of terminals in MIL-STD 1553 data bus

Question

Explain three types of terminals within the MIL-STD 1553 data bus?

Answer 1

Three terminals within the MIL-STD 1553 data bus includes:

a) Bus Controller,

b) Remote

c) Terminal and

d) Bus monitor.

Bus controller is accountable for directing the flow of data over the bus. It initiates the transfer of all the information. Bus controller too monitors the status of the system.

A bus monitor stores and receives the selected bus traffic. It will not reply to any traffic received, until the traffic is specifically addressed to it. They are normally used to receive and extract the data for off-line purposes like flight test, maintenance or mission analysis.

Remote terminals (RTs) are the greatest fraction of units within the 1553 bus system. Due to the 5-bit address field, there may be upto 31 RTs on the given bus. RTs reply only to the valid commands specifically addressed to them or to the valid broadcast commands.
