DMF32

This document is the official user guide for the DMF32 intelligent VAX family DMA UNIBUS controller. It provides a comprehensive overview of the hardware, which supports eight asynchronous lines, one synchronous line, and a line printer interface or parallel I/O port. The guide covers:

• General Description: Details on device configurations, physical components, and technical specifications.
• Installation: Procedures for module installation, distribution panel mounting, cabling, and verifying integrated system operation.
• Diagnostics: Instructions for using Level 3 (standalone) and Level 2R (VMS) diagnostic tools for fault isolation, including various loopback methods.
• Programming: Detailed register descriptions and operational guidelines for the synchronous interface, asynchronous multiplexer, line printer controller, and parallel interface.

Appendices provide information on connector pinouts and signal descriptions.
