The Astronics/EADS/Racal 1260-00B is a VXIbus Slot 0 Resource Manager that bridges IEEE-STD-488 (GPIB) controllers with VXIbus instrument systems. This module transparently converts GPIB signals and protocols to VXIbus format, enabling legacy GPIB hosts to command and manage VXIbus devices without controller replacement. The 1260-00B performs critical system initialization functions including device identification, address map configuration, self-test management, and commander/servant hierarchy establishment during power-up sequencing.
## Technical Specifications
• **Primary Function:** VXIbus System Slot 0 and Resource Manager
• **Interface Standards:** IEEE-STD-488 (GPIB) to VXIbus protocol conversion
• **Device Access:** VXIbus memory read/write, register-based device access, VME device support
• **Trigger Management:** VXIbus trigger line and protocol control
• **Configuration Modes:** Static and dynamic (switchless) configuration support
• **Operational Modes:** Commander or servant role capability within VXIbus hierarchy
## Key Features
• Transparent protocol translation between GPIB and VXIbus eliminates controller obsolescence
• Automated VXIbus device discovery and system address mapping
• Integrated system self-test initiation and management
• Direct memory and register access across VXIbus and VME address spaces
• C-size single-slot VXIbus module form factor
## Typical Applications
• Integration of GPIB-based test system controllers with modern VXIbus instrument platforms
• Mixed-protocol test systems requiring unified resource management
• System consolidation and controller redeployment across heterogeneous instrument sets
• Multi-instrument VXIbus chassis configuration and initialization
## Compatibility & Integration
The 1260-00B interfaces directly with VXIbus chassis backplanes and GPIB instrument networks. It is compatible with any IEEE-STD-488 controller and functions within standard VXIbus power and thermal specifications for C-size modules.
