Excalibur Systems EXC-4000cPCI Avionics Communication Carrier Board

The Excalibur Systems EXC-4000cPCI is a CompactPCI avionics communication carrier board engineered for integration into cPCI systems supporting simulation, testing, and embedded applications. Available in 3U and 6U form factors, this modular platform accommodates up to four independent, removable protocol modules, enabling flexible customization for diverse avionics communication requirements.

## Technical Specifications

**Form Factor & Architecture**
• 3U CompactPCI (cPCI)
• 6U CompactPCI (cPCI) variant available (EXC-4000cPCI6U)
• Supports up to four independent, removable modules (sold separately)

**Avionics Protocol Support**
The carrier board supports multiple protocol modules:
• **ARINC 429/575:** Up to 5 or 10 channels per module with error injection and detection. Receive channels feature label storage with status and time tag information, filtering, and multi-storage modes. Transmit channels employ instruction stack scheduling.
• **ARINC 708/453:** 2 channels per module
• **MIL-STD-1553:** Single-function (BC, RT, or BM operation) and multi-function modes. Multi-function channels operate simultaneously as Bus Controller and/or multiple Remote Terminals (up to 32), or as Triggerable Bus Monitor. Supports error injection and detection. Variants include M4K1553Px (BC, multiple RTs, BC/Concurrent-RT, BM), M4K1553PxS (BC, RT, or BM with RT validation), and M4K1553Px-1760 option for MIL-STD-1760 compatibility.
• **MIL-STD-1760:** Supported
• **Discrete I/O:** Up to 80 discrete channels via M4KDiscrete module. 20 programmable I/O discretes per module. Output discretes: open collector, 0-32 V, 100 mA max sink current. Input discretes record changes with time tags via 4092 Word FIFO (1023 discrete entries).
• **Serial Communications:** RS485, RS422, or RS232 with 2 or 4 channels per module
• **H009:** CCC and/or up to 16 concurrent Peripheral Units, or Bus Monitor operation via M4KH009 module
• **CAN:** 2, 4, or 6 channels per module (CAN 2.0B standard and extended)

## Key Features

• Modular design enables protocol customization without redesigning host systems
• Time-tagged discrete input recording with built-in FIFO buffering
• Multi-function MIL-STD-1553 operation supports simultaneous BC and RT modes on single channels
• Error injection and detection across supported protocols
• Instruction stack transmission reduces host CPU intervention

## Typical Applications

Avionics system simulation, flight test instrumentation, embedded communication processing, and protocol validation environments requiring multi-protocol support within constrained form factors.

## Compatibility & Integration

Designed for cPCI system integration. All protocol functionality delivered through removable modules purchased separately, allowing system optimization based on specific mission requirements.
