MIL-STD-1553 Modules

MIL-STD-1553 Cards with a Difference

> MIL-STD-1553B is the military specification defining a digital time division command/response multiplexed databus. The 1553 databus is a dual-redundant, bi-directional, Manchester II encoded databus with a high bit error reliability. All bus communications are controlled and initiated by a main bus controller. Remote terminal devices attached to the bus respond to controller commands.

MIL-STD-1553B defines specifications for terminal device operation and coupling, word structure and format, messaging protocol and electrical characteristics.

The first draft of a standard in 1968 by the Aerospace Branch of the Society of Automotive Engineers (SAE) laid the foundation for the US Air Force’s adoption of MIL-STD-1553 in 1973. Outside the US it has been adopted by NATO as STANAG3838. MIL-STD-1553 is often referenced as MilBus or simply 1553.

Detailed information about the standard as well as technical papers or articles can also be found at


AIM’s MIL-STD-1553 test, simulation, monitoring and analysis modules use our field proven Common Core hardware design giving you the best performance, best feature set and highest functional integration on the market. The use of SoC (System on Chip) based core designs with multiple processors for real time bus protocol and application support, massive memory and IRIG-B time code encoder/decoder functions are standard. The latest versions also support avionics discrete I/O.

AIM’s comprehensive line up of MIL-STD-1553 products are implemented as dedicated cards in various form factors or mezzanine cards (PMC/XMC) for embedded applications with conduction cooling support and rear I/O. 1553 PMC/XMC cards installed on our family of generic carriers provide highly flexible, modular and cost effective solutions. AIM can deliver versions with extended temperature range and conformal coating.

Single or multiple stream, dual redundant configurations offer concurrent Bus Controller (BC), Multiple Remote Terminals (MRT) 31, Chronological/Mailbox Bus Monitor operation with full protocol error injection/detection, multi-level triggering, advanced capture/filtering and real time bus recording, time stamping and physical bus replay to ensure your bus integrity. Single Function/Simulator Only variants support cost effective solutions.

Each module is delivered with a Board Support Package (BSP) containing the onboard driver software, a full Application Programming Interface (API) and detailed getting started and programming guides. Powerful databus test and analysis software is optionally available for all our MIL-STD-1553 cards.

For general MIL-STD-1553 applications AIM offers the necessary components including a range of third party MIL-STD-1553 cables, bus couplers in configurations up to 8 stubs in internally terminated and unterminated, as well as terminators, RFI caps, etc.
