Abaco Systems / VMIC VMIVME-2510B-110 64-Bit TTL Input / Output Board

The Abaco Systems / VMIC VMIVME-2510B-110 is a 64-bit TTL Input/Output board for VMEbus systems delivering 64 programmable digital I/O lines organized as eight 8-bit data registers. The module supports 8, 16, and 32-bit data transfers with individually configurable port direction control on a byte basis, making it suitable for industrial automation, test and measurement, aerospace, and medical equipment applications requiring precise digital signal management.

Technical Specifications

Interface & Architecture
• VMEbus compatible, standard form factor
• 64 Input/Output lines addressable within short supervisory or short non-privileged I/O map
• Eight 8-bit data registers, individually addressable on 8- or 16-bit boundaries
• Separate board address decoding for control and data registers
• Two sets of board address switches for flexible CSR and I/O address mapping

I/O Characteristics
• Data transfer sizes: 8, 16, 32-bit supported
• Sink capability: 64 mA per line
• Source capability: 15 mA per line
• Signal levels: TTL
• High-reliability DIN type connectors

Port Control & Direction
• Direction of each 8-bit port individually programmable on a byte basis
• Eight direction control bits in Control and Status Register (CSR) select input or output mode for each octal port

Built-in-Test & Diagnostics
• Supports off-line and on-line fault detection and isolation
• Output data readable in real-time or off-line mode via CSR TEST MODE bits
• Two TEST MODE bits enable independent testing of 32-bit connector I/O sections
• Off-line mode sets outputs to TRI-STATE for isolated verification
• Front-panel Fail LED indicates faults; illuminated at power-up/reset, extinguished upon successful diagnostics

Environmental
• Operating temperature: -20 °C to +70 °C

– Key Features

• Contiguous I/O address configuration conserves memory in multi-subsystem deployments
• Flexible data register addressing supports mixed transfer sizes within applications
• CSR-based direction programming eliminates external logic requirements
• Integrated diagnostics enable field troubleshooting without external test equipment

– Typical Applications

• Industrial automation and process control
• Test and measurement systems
• Aerospace avionics interfaces
