DWMVA VME Adapter Installation Guide

This document is the DWMVA VME Adapter Installation Guide, providing instructions for installing the DWMVA I/O adapter in VAX 6000 or VAX 7000/10000 computer systems equipped with a VMEbus expansion cabinet (e.g., BA62 enclosure).

Key aspects covered:

• Purpose: The DWMVA adapter establishes communication between a VMEbus and the VAX system's XMI bus.
• Components: The DWMVA kit includes two main modules (T2018 XMI module and C3200 VMEbus module), three cable assemblies (XMI internal, VME internal, and IBUS external) for interconnection, a blank panel, and optionally a BA62 VME enclosure.
• System Requirements: Specifies compatible VAX systems (6000 series with specific ROM versions, or 7000/10000 series), VMS operating system versions (5.4-3+ for VAX 6000, 6.0+ for VAX 7000/10000), and environmental conditions.

• Installation Procedures: Details the three main steps:

  1. Installing the T2018 module into the VAX's XMI card cage.
  2. Installing the C3200 module into the 6U VME card cage within the expansion cabinet.
  3. Connecting the three required cable assemblies to link the T2018 and C3200 modules.

• Verification and Troubleshooting:

  • Power-Up Self-Test: Automatic tests run by the VAX processor upon power-up, with status indicated by LEDs on the T2018 module.
  • EVCLA Tests: A diagnostic program (for VAX 6000 only) run from the VAX Diagnostic Supervisor (VAX/DS) to verify DWMVA operation.
  • Advanced Troubleshooting (EVCLC): Another diagnostic program (for VAX 6000 only) requiring the installation of a specialized Radstone PME 68-25 processor board in the VME cabinet.

The guide is intended for DWMVA VME adapter users and Digital customer service engineers.
