ADV11-A, KWV11-A, AAV11-A, DRV11 User's Manual

This document is a user manual for a family of real-time analog and digital I/O devices designed for the Digital Equipment Corporation (DEC) LSI-11 Processor.

The specific devices covered are:

• ADV11-A Analog-to-Digital Converter: A 12-bit successive-approximation A/D converter with a built-in multiplexer and sample-and-hold, supporting 16 single-ended or 8 quasi-differential inputs.
• KWV11-A Programmable Real-Time Clock: A 16-bit programmable clock/counter for time interval determination, event counting, and generating interrupts, featuring internal crystal-controlled frequencies, line frequency input, or Schmitt trigger inputs.
• AAV11-A Digital-to-Analog Converter: A 4-channel, 12-bit D/A converter module for the LSI-11 bus, providing programmable voltage outputs with adjustable ranges and modes.
• DRV11 Parallel Line Unit: A general-purpose interface for connecting parallel-line TTL or DTL devices to the LSI-11 bus, supporting 16-bit input and latched output lines.

The manual provides comprehensive information on the operation, installation, and maintenance of these modules. Each device has a dedicated chapter detailing its functional description, specifications, theory of operation, and programming guidelines. Chapter 6 specifically covers installation and maintenance procedures applicable to all units.

These devices are designed to interface between the LSI-11 processor and external analog or digital signals, are configured on quad or double-height boards for LSI-11 backplanes, communicate via the LSI-11 bus, and allow users to assign device addresses and interrupt vector locations.
