DEC EtherWORKS MC/TP_BNC Owner's Manual

This document is the Owner's Manual for the DEC EtherWORKS MC/TP_BNC board, a communications option for IBM PS/2 personal computers with a Micro Channel bus.

Purpose: The manual provides comprehensive instructions for installing and configuring the board, enabling the PS/2 system to connect to either a ThinWire (BNC) Ethernet network or a Twisted-Pair (RJ45) Ethernet network.

Key Contents:

• Installation & Configuration: Covers preparing the PS/2 system, selecting the network interface type via shunt connector, physically installing the board into an option slot, configuring board settings using an adapter description file (ADF) for features like interrupt lines and memory addresses, and connecting to the chosen Ethernet network.
• Problem Solving: Offers guidance on fault isolation by symptom, interpreting LED activity (amber for self-test, green for network activity), and recovering from self-test errors with corresponding error codes and recommended actions.
• General Information & Specifications: Details the board's physical description (three-quarter length, 16-bit bus), functional components (e.g., LANCE controller, network interfaces, buffer RAM, ROM), electrical specifications (power requirements), and operating environment constraints.
• Cable Specifications: Provides detailed requirements for unshielded Twisted-Pair and ThinWire Ethernet cables, including wire specifications, lengths, impedance, and environmental constraints for reliable network operation. It also includes an optional ROM installation procedure.

Important Notices: The document prominently features an FCC notice (Part 15), stating that the device complies with regulations, must accept interference, and may not cause harmful interference. It specifically prohibits the use of unshielded Ethernet cable on BNC ports with this equipment to ensure compliance with FCC Class B regulations. Static electricity precautions are also emphasized for handling components.
