Sital Extends the MultiComBox Tester with EBR 1553 Capabilities

Posted on by Sital_web3D

EBR-1553 operates at a 10Mbps bit rate and employs the resilient Mil-Std-1553 protocol through RS-485 transceivers in a point-to-point connection hub. Employing a star-based network topology between Remote and BC Terminals facilitates resilient and rapid data transfer.
EBR-1553’s communication speed is significantly faster than traditional MIL-STD-1553’s 1Mbps. This high-speed capability is crucial for applications requiring rapid data transfer and real-time processing. The adoption of RS-485 transceivers in a point-to-point hub enhances the reliability and speed of data exchanges between terminals, supporting the demands of advanced avionics and military communication systems.

The implementation of a star-based network topology in EBR-1553 systems facilitates more efficient and resilient data transfers. Unlike the bus-based structure of standard MIL-STD-1553, this topology allows for direct, isolated connections between the bus controller (BC) and each remote terminal (RT), minimizing the potential for data collision and ensuring a higher degree of network stability in critical communication environments.

EBR supports various modes of operation – “SPEC” mode, “SWITCH” mode and “LINK” mode.

SPEC mode is similar to the standard 1553 protocol, where the BC sends the message in all ports, all RTs receive the message, and only the RT with the appropriate RT address should respond.

In SWITCH mode the BC sends the message only on the port where the particular RT is connected. For example, if a message is intended for RT 6, then it will be transmitted only on port 6, and the message will contain the RT address 6.

In LINK mode, the message is transmitted only on the appropriate port which corresponds to the required RT address (for example – port 6), but the RT actual address on the message command is ‘0’ for all RTs. This means that any RT that receives a message in this mode, with the RT address ‘0’ should answer to the message. Therefore, RTs are physically connected to the corresponding ports on the BC.

In MultiComBox Sital supports all three modes of operation, offering unprecedented flexibility in communication strategies. These modes allow system architects to tailor data transmission approaches to specific operational requirements, whether it’s broad message broadcasting in SPEC mode, targeted communication in SWITCH mode, or uniform addressing in LINK mode, enhancing the system’s adaptability to various mission scenarios.

By supporting all three operational modes of EBR-1553, the MultiComBox tester becomes an invaluable tool for developers and engineers working on a wide range of communication systems. This versatility ensures that the tester can adapt to varying project requirements, from simple setups to complex configurations, providing a solid foundation for the development, testing, and implementation of advanced communication protocols within the aerospace and defense sectors.

The extension of the MultiComBox tester to include EBR-1553 capabilities represents a significant advancement in testing and validation tools for communication systems. This enhancement allows for comprehensive testing across all operational modes of EBR-1553, ensuring that systems are rigorously evaluated for performance, reliability, and compliance with the enhanced bit rate standard, thereby supporting the development of more robust and efficient avionics systems.

Sital Announces the Release of the BRD1553 PC104 PC104 Multi Interface Board

Posted on by Sital_web3D

Sital Technology announces the launch of its new PC104+ board, an efficient and robust platform for avionics communication bus applications.

The BRD1553PC104 Board is a PC-104+ Card, a versatile multi-standard board featuring two dual-redundant Mil-Std-1553 channels. It offers compatibility with Mil-Std-1760 and Mil-Std-1553B, allowing independent configuration of its channels for collaboration with WB-194, EBR1553, and H009 in tandem with 1553. Additionally, upon request, support for other protocols like French DigiBus is also provided.

Its ability to support a range of protocols makes it highly versatile in diverse avionics systems, ensuring seamless communication across different platforms.

Further enhancing its versatility is the BRD1553PC104 Board, which leverages FPGA technology for optimal performance. The use of this FPGA-based architecture supports the implementation of complex communication protocols on a single compact board. It allows for rapid reconfiguration of the board to support different avionics communication standards and custom functionalities.

This blend of features makes it ideal for applications requiring multi-standard compatibility and high reliability.

Built upon Sital’s established H009, 1553, and WB-194 (WMUX) IP cores, the PC-104+ Board utilizes an FPGA (Field Programmable Gate Array) component along with individual transceiver components. Sital provides programming capabilities for the board, offering the flexibility to accommodate different sets of protocols and configurations using identical hardware. It includes 8 Generic I/O pins, that could be utilized as RS-485/RS-422, and also includes ARINC-429 (8 transmit channels and 16 receive channels) or eight avionics I/O. Moreover, it incorporates 8 digital I/Os and includes input and output channels for IRIG-B time tagging.

These extensive input/output capabilities enable the integration of a wide range of avionics devices and sensors. It also supports complex applications that require multiple data transfer and communication interfaces.

The inclusion of two dual-redundant Mil-Std-1553 channels makes it possible to configure each channel independently. In turn, this enhances the system’s fault tolerance by ensuring continuous operation even in the event of a channel failure. This capability is crucial for mission-critical military and aerospace applications where communication integrity is paramount.

The board’s support for IRIG-B time tagging is a critical feature for applications requiring precise timing and synchronization, such as data acquisition and telemetry systems. The ability to tag data with accurate timestamps enhances data integrity and allows for the precise correlation of events in complex avionics systems, improving system analysis and troubleshooting capabilities.

The BRD1553PC104 Board’s advanced programming flexibility facilitated by its FPGA-based design supports advanced programming flexibility. This flexibility allows developers to customize and update the board’s firmware to meet specific application needs, including the implementation of custom protocols or the integration of additional functionality.

Such programmability is invaluable in rapidly evolving avionics environments, enabling users to adapt to new standards or requirements. It eliminates the need for frequent hardware replacements, thus ensuring a future-proof solution for a wide array of avionics communication tasks.

The board’s architecture is designed to optimize data handling, offering efficient processing and routing of avionics data. This enhances system performance by ensuring smooth and reliable data flow between various avionics systems and components, crucial for operational efficiency and safety.
