Astronics / EADS / Racal 1260-00B Slot 0 / Resource Manager

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.
