GE PCI5565 Multi Channel MIL-STD-1553 Interface Card

GE PCI5565 Multi Channel MIL-STD-1553 Interface Card

Product core positioning and application scenarios

（1） Positioning

PCI5565 is a high-performance MIL-STD-1553 interface card based on the PCI bus, designed to meet the MIL-STD-1553A/B standard (military data bus standard, used for reliable transmission of critical data in aviation electronics, spacecraft and other systems), supporting multi-channel and multi role 1553 bus communication (bus controller BC, remote terminal RT, bus monitor BM), with high stability and flexible scalability, suitable for scenarios with strict requirements for data transmission security and real-time performance.

（2） Typical applications

Avionics system: data exchange between avionics equipment of fighter jets and passenger planes (such as engine parameters, navigation information, and flight control system command transmission).

Space system: Communication of onboard equipment for satellites and spacecraft, data acquisition and command issuance for ground testing and control platforms.

Military ground equipment: internal and external data bus connections for radar systems, command and control systems, and weapon equipment testing platforms.

High reliability industrial control: Some industrial automation systems that require extremely high fault tolerance and anti-interference capabilities (such as key control modules in the energy and transportation fields).

Core functional characteristics

（1） 1553 bus communication capability

Multi channel and multi role support

Provide 2 independent 1553 channels, each channel can be flexibly configured as a bus controller (BC), remote terminal (RT), or bus monitor (BM) role, and each channel role can be independently set to meet the communication needs of multiple nodes in complex systems.

Supports multiple role combinations such as "BC+RT", "Dual RT", "BC+BM", etc. A single channel can simultaneously achieve BM function (monitoring bus data) and BC/RT function (participating in data transmission).

Protocol and Data Processing

Fully compatible with MIL-STD-1553A/B standard, supporting all standard 1553 message formats (such as standardized transmission of command words, data words, status words), including special communication scenarios such as broadcast messages and mode code instructions.

Built in hardware level message processing engine, capable of automatically encoding/decoding 1553 messages, error detection (such as parity errors, format errors, bit errors) and correction, reducing CPU usage and ensuring real-time performance (message processing latency as low as microseconds).

Support message priority configuration, which can set high priority for critical data (such as emergency control instructions) to ensure their priority transmission.

（2） PCI bus interface characteristics

Compatible with PCI 2.2 standard, supports 32-bit data bus width, operates at a frequency of 33MHz, conforms to the interrupt request (IRQ) mechanism of PCI local bus specification, and is compatible with mainstream x86 architecture and embedded PCI motherboards.

Supports Plug and Play (PnP) functionality, which can automatically recognize hardware parameters (such as base address and interrupt number) through the system BIOS or driver program, simplifying the installation and configuration process.

（3） Hardware Enhancement and Reliability Design

Anti interference and fault tolerance capability

The 1553 bus interface adopts optocoupler isolation design (isolation voltage ≥ 2500Vrms), effectively suppressing electromagnetic interference (EMI) and radio frequency interference (RFI), reducing the impact of external noise on bus communication, and meeting military grade electromagnetic compatibility (EMC) requirements.

Built in bus fault detection and protection mechanism. When a bus short circuit, overload or abnormal signal is detected, the local circuit protection interface card and external bus devices can be automatically cut off. After the fault is restored, communication can be automatically restarted.

Storage and caching

Each 1553 channel is equipped with an independent message cache area (with a typical capacity of 64KB or higher), supporting pre storage and post reading of messages to avoid data loss caused by CPU response delay, especially suitable for high-throughput communication scenarios.

Support non-volatile storage (such as EEPROM), which can save user configuration parameters (such as channel roles, message formats, interrupt triggering conditions). The parameters will not be lost after the system is powered off and will be automatically loaded after restart.

（4） Software Support and Tools

Provide a complete driver package that supports Windows (XP/7/10), Linux (mainstream distribution), and VxWorks (embedded real-time operating system). The driver interface is compatible with industry standard APIs (such as GE specific API and MIL-STD-1553 universal programming interface), making it easy for users to quickly develop applications.

The supporting bus monitoring and configuration tool can display the real-time status of 1553 bus data transmission (such as message content, transmission rate, error statistics), support visual setting and saving of configuration parameters, and provide data logging function for system debugging and troubleshooting.
