DEC TRNcontroller 100 Hardware Installation

This document is a Hardware Installation Guide for the DEC TRNcontroller 100 Q-bus-to-Token Ring Adapter (DEQRA), published in August 1992.

The guide provides comprehensive instructions for configuring, installing, and validating the DEQRA board in a Digital Equipment Corporation VAX™ Q-bus-based computer. It is intended for Digital Customer Services personnel and self-maintenance customers.

Key areas covered include:

• Technical Specifications: Power and environmental requirements for the DEQRA.
• Antistatic Precautions and Inspection: Procedures for unpacking, inspecting, and safely handling the DEQRA board to prevent electrostatic discharge damage.
• Hardware Configuration: Detailed steps for setting the board's switches for shared memory base address, Control/Status Register (CSR) address, and interrupt vector address, as well as positioning the shared memory ENABLE jumper (JP1).
• Physical Installation: Instructions for mounting the DEQRA board into a BA200/400 series enclosure, including the proper use of gap filler assemblies, and connecting it to the Token Ring Network.
• Power-Up Diagnostic Tests: Guidance on running power-up diagnostics to validate the DEQRA's hardware functionality after installation, explaining the meaning of LED display patterns during various "basic checks" (e.g., EPROM, RAM) and "device tests."
• Software Context: Notes that the DEQRA works with the DEC Token Ring Network Device Driver for VMS (TRDRIVER) software, which is installed after the hardware.
