The Excalibur Systems EXC-4000PCI is a half-size PCI carrier board engineered to host up to four independent, removable 4000 family avionics communication modules. This 8/16-bit PCI-compliant interface enables flexible integration of multiple avionics protocols—including ARINC 429/575, MIL-STD-1553, CAN Bus, and discrete I/O—onto a single board for aerospace and defense applications spanning simulation, data acquisition, and real-time communication.

• Hardware-in-the-loop (HWIL) test environments
## Compatibility & Integration
The EXC-4000PCI operates as a modular host platform. All protocol-specific functionality derives from interchangeable 4000 family modules (sold separately). System configuration and channel assignment are performed in real-time via software control.
**Status:** End-of-Life (EOL)
