Couplers for MIL-STD-1553 Data Bus

Dual 3 Stubs 1553 Coupler with PXI Panel

Sital’s MIL-STD-1553 coupler is a critical component designed to ease the challenges associated with the configuration and deployment of data buses. We look into the sophisticated design and functionality of Sital’s MIL-STD-1553 coupler, highlighting its role in enhancing the performance and reliability of communication networks.

Advanced Design for Optimal Performance

Sital’s MIL-STD-1553 coupler is crafted to offer flexibility and high performance in various configurations. This coupler features a dual three-stub configuration. It introduces an optional internal bus termination for each three-stub coupler for smooth integration and termination of data buses.

This design not only enhances the coupler’s utility but also allows for a customizable approach to system configuration, accommodating either six-stub couplings for a single data bus or separate three-stub couplings for multiple buses.

Installation and Configuration

The practicality of Sital’s coupler is evident in its accommodation for optional mounting accessories, suitable for both 3U and 6U PCI or cPCI/PXI chassis. This adaptability ensures a dense, optimized organization within rack-mounted and portable test systems. This option facilitates a more condensed and efficiently arranged setup for testers mounted in racks.

All links and terminations are made possible through the utilization of the conventional D-Type 25 connector. When the termination is connected during live messaging, an LED illuminates to indicate ongoing bus activity and use.

Sital’s MIL-STD-1553 coupler is not only designed for optimal performance and flexibility but also for reliability and durability. Incorporating user-friendly features, the coupler includes thoughtful additions to troubleshooting and monitoring the system’s performance in real-time. Here are its features:

  • Compact size: ideal for test equipment racks
  • Single D-type 25-pin plug connector
  • Reduced system expenses – minimizes the need for wires and Triax plugs
  • MIL-PRF 21038/27 Internal Transformers
  • Includes six transformer-coupled 1553 stub connections
  • Internal coupling transformers provide compliance with MIL-STD-1553
  • Can be configured as either two 3-stub couplers or one 6-stub coupler
  • Includes two internal 78-ohm termination resistors enabling multiple configurations
  • Optional unique PCI or cPCI/PXI rack assemblies fittings
  • Flexible mechanical support for other rack assembly fittings
  • Compact and lightweight design
  • Termination activated through adjustment in connector terminals
  • LED activity signal on each coupler to indicate bus activity

Sital’s MIL-STD-1553 coupler offers a blend of performance, flexibility, and reliability. Designed to meet the rigorous demands of military and avionic communication systems, it facilitates the configuration, installation, and operation of data buses. The coupler represents a significant advancement in the field with its compact size, broad features, and compatibility with rack-mounted systems. For those looking to enhance the integration and efficiency of their MIL-STD-1553 data buses, Sital offers a solution that embodies precision, durability, and ease of use.
