KMV1A-S Communications Controller for the BA200-Series Enclosure

This document is an Installation Guide for the Digital Equipment Corporation (DEC) KMV1A-S series Programmable Communications Controller, designed for use in BA200-series microsystem enclosures.

Intended for DEC field service personnel and qualified self-maintenance customers, the guide provides comprehensive, step-by-step procedures covering:

1. Pre-Installation: Emphasizing software backup, system shutdown, anti-static precautions, and verifying the existing system's functionality.
2. Installation Procedures: Details unpacking and inspecting the option kit, checking system configuration (power and bus loads), guidelines for proper module placement to ensure bus continuity, and instructions for relocating existing modules.
3. Configuration Settings: Explains how to determine and set critical CSR (Control/Status Register) addresses and interrupt vectors using either the SYSGEN CONFIG utility (for MicroVAX systems) or provided tables, along with setting interface and self-test switches.
4. Post-Installation: Steps for verifying ground connections and connecting external devices using specific cables (BCC 04 for KMV1A-SF, BC 18Y for KMV1A-SG/SH).
5. Testing the Configuration: Provides diagnostic procedures for both MicroVAX and MicroPDP-11 systems to test the newly installed KMV1A-S, including advice for troubleshooting.

The KMV1A-S is a microprocessor-based quad-height board for Q-bus based systems, supporting bit-oriented, byte-oriented synchronous, and asynchronous protocols. It comes in different options (KMV1A-SF, -SG, -SH) corresponding to RS232-C, RS422-A, and RS423-A electrical interfaces, respectively.
