The Interphase V/Ethernet 4221-1PT-AUI/UPT-128 Condor is a single-channel Ethernet motherboard for VMEbus systems, providing dual network connectivity through AUI and 10BaseT interfaces. Built on the Condor architecture—the second-generation multifunction I/O Host Bus Adapter platform—this board delivers scalable performance and cost efficiency for embedded networking applications requiring flexible media options.
## Technical Specifications
**VMEbus Interface**
• 8-, 16-, 32-bit VMEbus Master DMA capability
• 25 Mbytes/second Master Mode Burst/Sustained D32 transfer rate
• Programmable VME interrupt levels and vectors
**Ethernet Channel**
• Single Ethernet channel with dual connectivity
• AUI (Attachment Unit Interface) connector for legacy media and external transceivers
• 10BaseT (UPT) via standard RJ45 connector for unshielded twisted pair networks
**Architecture & Memory**
• Condor architecture supporting up to four Front End Channels (FECs)
• Large on-board memory buffer for packet storage and processing
• VMEbus DMA engine for efficient data transfer
• Integrated CPU core with dedicated memory area and host bus interface
• FECs interface directly to local bus
## Key Features
• Dual Ethernet connectivity eliminates media adapter requirements
• 25 Mbytes/second sustained throughput enables real-time data acquisition and control
• Programmable interrupt/vector configuration simplifies integration into diverse VMEbus architectures
• Modular Condor design allows multi-channel expansion up to four FECs in scalable configurations
• On-board CPU and memory buffer reduce host processor overhead
## Typical Applications
Embedded network I/O for VMEbus real-time systems, industrial data acquisition platforms, telecommunications infrastructure, and legacy system network upgrades requiring backward compatibility with both AUI and modern 10BaseT networks.
## Compatibility & Integration
Designed as a VMEbus master adapter supporting 8-, 16-, and 32-bit transfers. Integrates within the Condor product family architecture for systems requiring single or multi-channel Ethernet connectivity. Compatible with standard VMEbus backplane implementations.
