Overview
1553 Solutions products are a market leader in MIL-STD-1553 system simulation. With what is possibly the largest installed base of commercially available 1553 boards in the world, 1553 Solutions engineers have the experience and technological know-how to continually keep pace with customers' requirements in hardware development, simulation testing, systems integration, production testing, bus analysis, and flight line and field testing.
Now in their fifth generation, MIL-STD-1553 Solutions products have continued to evolve to meet changing market needs. Our 1553 Solutions Gold+ Series boards employ custom microcode to replace industry standard protocol chips, allowing them to simultaneously emulate a Bus Controller, up to 31 different Remote Terminals, and to act as a Bus Monitor. It is this custom microcode that has become the hallmark of the 1553 Solutions line. The flexibility and cross-platform compatibility offered by this approach truly revolutionized the 1553 industry.
The Gold+ Series consists of single and multi-function boards. Single function boards are used for applications such as monitoring 1553 bus traffic. Multi-function boards can inject errors into 1553 bus traffic and have the ability to perform more than one function at a time. They are used for system simulation and test applications that also need electrical and protocol error injection.
All single-function boards use the same subset of microcode and use the same hardware platform as their multi-function counterparts. A powerful Texas Instruments® Digital Signal Processor executes the microcode that performs all 1553 A/B functions. An extensive set of bus instructions allows each board to execute a 1553 bus list with minimal host overhead or intervention. All Gold+ boards can act as a bus controller (BC), can emulate multiple remote terminals (MRT), and can function as a complete chronological bus monitor (BM).
Bus Controller Mode
Gold+ Series boards have a powerful bus controller with an extensive bus instruction set. To track bus list execution, the user has a choice of methods, including reading the Current Bus Instruction Address Register, checking the buffer transmitted/received bit, or generating an interrupt for any particular bus instruction. Bus instructions include all 1553 commands: Jump to Sublist, Jump on Status Exception, Jump on Protocol Error, Return, Unconditional Hum, Reset Stack, Wait, Delay, Pause and Halt. An interrupt can be enable for any instruction, allowing the host CPU to track bus list status or the execution of specific messages. The bus list can be synchronized to external events via an RS-422 input signal and the Pause command. A discrete output signal can also be enabled to notify another device of the execution of any bus instruction.
Multiple Remote Terminal Mode
All Gold+ Series boards, both single-function and multi-function, have the ability to emulate up to 32 RTs. This differentiates them from all protocol chip-based 1553 single-functions products on the market. Selection of 1553A or B protocol form emulation can be done at the subaddress (SA) level.
Chronological Monitor Mode
In monitor mode, Gold+ Series boards can capture all bus traffic or automatically filter bus traffic by RT, subaddress, and direction which saves memory. While capturing all bus traffic chronologically, interrupts can be enabled for specific events, allowing the host to quickly find certain messages in the chronological buffers.
Maximum Flexibility
Each board in the memory-mapped Gold+ Series provides the optimal interface between a host CPU and one or more 1553 buses. The user can employ either a sophisticated interrupt handling mechanism (with interrupt queuing) or polling to track board status. The linked data buffer architecture of the Gold+ boards allows maximum flexibility in setting up any BC or multiple RT simulation. Double buffering is one of the many storage mechanisms the boards support.
True Dual Channels
Dual-channel Gold+ Series boards (two A and two B buses) are the equivalent of two boards in one slot. They feature dual processor, independent RAM and I/O for all setup and control functions and buffers.
Gate Array Technology
Gold+ Series multi-function boards use gate arrays. This technology maximizes reliability and minimizes power consumption, especially when compared to discrete TTL-based designs. The reduced part count also creates a simplified layout and design which decreases the board's operating temperature.
Common Software Interface
The latest generation of 1553 Solutions, designated the Gold+ series, achieves both hardware and software compatibility between single- and multi-function boards.
Applications
Our 1553 Solutions can be used in a broad range of MIL-STD-1553 communication and simulation applications, including 1553 A/B, and mixed device bus simulations. Typical applications include:
- Hardware development
- Simulation testing
- Systems integration
- Production testing
- Bus analysis
- Flight line testing
- Field testing
For greater flexibility in creating MIL-STD-1553 simulations and test scenarios, our MBX 1553 Bus Switch provides "virtual patch panel" capability for up to 16 buses or devices.
