Tektronix / CDS 73A-851 VME/VXI to VXI Adapter Module Description

Functions

Provides interface conversion between VME/VXI bus architectures and VXI instrumentation systems. Enables VME-based controllers and processors to communicate with VXI measurement modules through standardized backplane connections. Performs bus protocol translation, signal conditioning, and timing synchronization between different instrumentation standards. Facilitates integration of mixed-architecture test systems by bridging electrical and logical interfaces. Supports automated test equipment configurations requiring cross-platform instrument control and data acquisition capabilities.

Platforms

VMEbus and VXI platforms for signal processing and data acquisition; facilitates communication and interoperability between VME/VXI systems and VXIbus systems; connects via VXI slots, enabling integration with VXI mainframes and modules; supports VXI Plug&Play standards; typically used in automated test equipment, instrumentation control, and modular electronic systems in aerospace and defense applications.

Applications

Provides electrical and mechanical interface adaptation allowing double height VMEbus or B size VXIbus modules to be installed and operate in a C size VXIbus mainframe slot. It actively transceives VME/VXI backplane address, data, and control buses while maintaining proper timing and signal loading for seamless communication between VME and VXIbus systems. Supports bus master and slave modules, with options enabling access to P2 connector rows for extended signal lines, facilitating integration and interoperability in modular test and measurement platforms.

Accessories

**Accessories:** Requires VME chassis or backplane with P1 and P2 connectors (96-pin DIN 41612). VXI backplane with standard VXI slot spacing required for target side. VME bus interface cables may be needed depending on chassis configuration. Power supply must provide +5V, +12V, -12V, and -5.2V rails per VME specification. VXI-compliant controller module required for VXI bus operation. Interface includes VME P1 connector (96-pin, rows A-C) for data/address lines and P2 connector (96-pin, rows A-C) for user-defined signals and additional power distribution.

Interfaces

VME P1/P2 96-pin DIN connectors for backplane connection, VXI P1/P2 96-pin DIN connectors for VXI chassis interface, supports A16/A24/A32 addressing modes, D08/D16/D32 data transfer widths, VMEbus to VXIbus protocol translation, interrupt handling between VME and VXI domains, requires VME chassis slot and VXI mainframe slot for operation, enables VME controllers to access VXI instruments, bidirectional communication bridge between bus architectures

Specifications

Electronic adapter module designed to enable interoperability between VME and VXI bus platforms. Provides signal translation, mechanical conversion, and electrical compatibility between VME backplanes and VXI instruments. Features include address space mapping, trigger routing, clock synchronization, and protocol handling. Supports multiple VXI message-based and register-based operational modes. Compatible with IEEE-1014 VME and VXIbus specifications. Facilitates integration of VME cards into VXI mainframes with automatic configuration capabilities. Used in automated test environments, electronic instrumentation systems, and laboratory measurement applications requiring mixed VME/VXI architectures.
