DEC EtherWORKS Turbo/TP Ethernet Controller User Information

This document is the user manual for the DEC EtherWORKS Turbo/TP Ethernet Controller, a bus adapter board designed to integrate IBM/AT and compatible personal computers into an Ethernet network. It supports both IEEE 10BaseT Twisted-Pair and ThickWire Ethernet cabling.

The manual provides comprehensive instructions across several key areas:

1. Installation: Details how to prepare the computer, select the network interface (10BaseT or ThickWire via a shunt connector), physically install the board into a 16-bit option slot, reconnect the system, and perform an initial power-up self-test. It also directs users to the installation diskette for software drivers.
2. Configuration: Explains how to adjust the board's 12 switches to prevent conflicts with other computer components. This includes setting:
   • Memory addressing range and size (e.g., 64KB or 32KB buffer, default D0000-DFFFF).
   • I/O address (default 300-30F).
   • Remote boot enablement and timeout period (if an optional ROM chip is installed).
   • Interrupt Request Line (IRQ) selection (default IRQ5).
3. Problem Solving: Offers troubleshooting guidance based on various symptoms (e.g., no display, system hangs, network not starting) and specific self-test error codes. It explains the meaning of the board's amber (fault) and green (network activity) LED indicators.
4. General Information & Specifications: Provides physical descriptions, functional components, environmental requirements, and detailed system specifications, including power requirements and supported I/O, memory, and IRQ ranges.
5. Cabling Requirements: Outlines specifications for unshielded twisted-pair and ThickWire transceiver cables, including length limitations and environmental constraints. It also notes FCC regulations prohibiting unshielded Ethernet cables for ThickWire AUI port connections to ensure Class B compliance.
