This unit
The Abaco Systems PMC421 is an 8-port serial interface module designed for integration into VMEbus, CompactPCI, and specialized processor-based systems via PMC connector. The module features an onboard 32-bit RISC CPU (i960VH) that offloads host processing, implements character blocking, and manages DMA operations for efficient PCI utilization across all eight fully independent ports.
Technical Specifications
- Serial Protocols: RS232, RS422, RS485 (full and half duplex)
- Port Count: 8 independent ports
- Baud Rate: 150 bps to 1.5 Mbps (software selectable)
- Onboard Processor: 32-bit RISC CPU (i960VH), external bus 33 MHz, internal clock 100 MHz
- Memory: 4 Mbytes local DRAM for firmware execution and character data buffering
- PCI Interface: Revision 2.1 compatible, 33 MHz/32-bit transactions, slave and master operation with DMA engines for extended bursts
- Firmware: Auto-loaded from local FLASH memory on power-up; field upgradeable without module removal
- Form Factor: PMC (PCI Mezzanine Card)
- I/O Configuration: Front or rear I/O options available
Key Features
- Onboard CPU eliminates host processing bottlenecks for serial data
- Processor directly controls UARTs and signal drivers for complete software configuration
- Independent port operation allows simultaneous multi-protocol communication
- DMA capability optimizes PCI bandwidth utilization
- Custom firmware options support specialized applications
Typical Applications Embedded industrial systems, avionics platforms, defense instrumentation, telecommunications infrastructure, and test automation requiring multi-port serial connectivity with autonomous onboard processing.
Compatibility & Integration Directly compatible with current-generation VMEbus and CompactPCI single board computers, plus any special-purpose processor featuring a PMC connector. Integration with card-edge PCI systems requires the PMC239 adapter. Product Status: Entered Restricted Production Phase (RPP) as of December 31, 2010.
