EBR-1553 is a communication standard based on MIL-STD-1553, but specified to operate at a higher data rate of 10 Mb/s. EBR-1553 operates over a hub (star) topology, with the Bus Controller (BC) node at the center of the hub and RTs located on the spokes.

The EBR-1553 physical layer calls for point-to-point connections using RS-485 transceivers.

EBR-1553 is based on MIL-STD-1553’s familiar command/response protocol, thereby enabling deterministic communication and providing error detection.

In addition to its 10 Mb/s data rate, the MIL-STD-1553 response time and inter-message gap time values are modified for 10 Mb/s operation. EBR-1553 is deployed on weapon systems, including the Small Diameter Bomb (SDB).

Sital’s EBR-1553 products includes an IP core.

This core provides:

  • DDC’s Enhanced Mini-ACE register/memory architecture
  • BC, RT and Monitor operation
  • A hub that can be instantiated to provide any number of ports up to and including 32.

The core can be supplied with software API/library/drivers for Windows, VxWorks and Linux.

The API/library/drivers provide the same API that Sital provides for is MIL-STD-1553 IP and standard (single-function) boards and is also compatible with DDC’s AceXtreme API.

Sital also offers EBR-1553 boards in a variety of form factors, including PCI Express, PCI, PMC, VME, PC/104, Compact PCI, and USB.

Two versions of boards are available: standard interface boards and tester boards.

Both versions of EBR-1553 boards provide BC, RT and Monitor operation and include 4-port EBR-1553 hubs, along with Windows API/library/driver software.

In addition, the tester versions of the boards provide error-injection capabilities and also include the COMposer Windows GUI software.

MIL-STD-1553 Safe and Secure

For most of its MIL-STD-1553 solutions, Sital offers an option for its Safe and Secure (SnS) Technology. By means of enhanced physical layer signal monitoring, Sital’s SnS provides continuous cyber authentication for detecting “spoofing” (or impersonating) nodes on 1553 buses. In addition, Sital’s SnS also provides electrical fault detection. This enables detection and locating of faults such as intermittent or continuous open or short circuits in data bus and stub cabling, couplers, connectors, connected LRUs and termination resistors.
