The Abaco Systems/VMIC VMIVME-2511-400 is a 48-bit digital parallel input/output board engineered for VMEbus system integration. This board delivers flexible parallel I/O functionality through a dual-port architecture, enabling orderly data transfer between host systems and peripheral devices via handshake-controlled interfaces.
– Technical Specifications
The board implements the 68230 Parallel Interface and Timer IC as its core I/O controller. It provides 48 bits of digital parallel I/O distributed across two ports (Port A and Port B), each capable of independent operation. Every 8-bit port features double-buffering to support efficient data staging and retrieval. Each port includes two dedicated handshake lines that manage the timing and sequencing of parallel data transfers, eliminating race conditions and synchronization errors in multi-device environments.
– Key Features
• 48-bit parallel digital I/O capacity
• Double-buffered 8-bit port architecture
• Dedicated handshake control lines per port
• 68230 Parallel Interface and Timer IC implementation
• VMEbus form factor compliance
– Typical Applications
This board suits industrial control systems, automated test equipment, data acquisition platforms, and legacy VMEbus-based instrumentation requiring direct parallel device communication. Its handshake-driven design makes it particularly effective in applications demanding synchronized data exchanges with external logic or sensor arrays.
– Compatibility & Integration
The VMIVME-2511-400 integrates directly into VMEbus backplane architectures. Its parallel I/O interface supports standard parallel data transfer protocols, making it compatible with a broad range of digital peripherals and legacy industrial equipment designed around VMEbus ecosystems.
