This document serves as a configuration guide for the KDJ11-A module. It details the functionality of nine user-selectable jumpers, including power-up options, halt operations, boot address selection, wakeup circuit control, and BEVNT recognition. The guide also explains the factory configuration and includes a troubleshooting section that interprets diagnostic LED (D1-D4) states to help identify system failures such as CPU module issues, LSI-11 bus problems, memory system failures, or console terminal inactivity.
