DN92 Remote Station Users Guide Apr78

This document, the "DN92 Remote Station User's Guide" (April 1978), provides comprehensive instructions for users, operators, system programmers, and maintenance personnel of the DN92 remote station. The DN92 is a PDP-8A based remote station that connects to a DECsystem-10 host within a multilink/multinode network, acting as a boundary node.

The guide covers:

• Introduction: Describes the DN92's role in a DECsystem-10 network, the initial software loading process from the host, and basic user login procedures. It also mentions the automatic execution of the SYSCHK hardware diagnostic program upon successful loading.
• Operator Procedures: Details how to start the DN92 remote station, check hardware with SYSCHK, and configure operator programs (like LPTSPL for line printers and SPRINT for card readers) to support station peripherals.
• Station Peripherals: Provides operational guidelines for common peripherals, including the LA180 Dot Matrix Printer and the LP05 Drum Printer (paper loading, ribbon changing, power controls, and alarm indicators with corrective actions), and the card reader (power, card loading, and troubleshooting front/back panel switches and lamps).
• Troubleshooting: Explains how to manually restart DN92 software using the operator's console, interpret various station error messages (including those from SYSCHK), examine remote station memory, and use the DDT92 debugger for more advanced diagnostics.
• Appendices: Offer technical details on State and Status Registers and a complete list of SYSCHK error messages.

The document aims to enable effective operation, maintenance, and problem resolution for the DN92 remote station running TOPS-10 Version 6.03.
