Digital Ethernet Multiport Office Network Repeater Installation

This document is the "Installation Information" guide for the Digital Ethernet Multiport Office Network Repeater (Order Number: EK-DEMON-IN. A01), published by Digital Equipment Corporation and dated January 1993.

The repeater expands networks using five shielded or unshielded twisted-pair ports, amplifying, retiming, and retransmitting signals up to a maximum cable distance of 100 meters per port.

The guide provides instructions for installing the unit, including:

• Mounting: Horizontally or vertically, preferably using the included adhesive-backed Velcro pads or optional screws.
• Connecting Power: Wiring the power cord from a wall receptacle to the power supply, and then connecting the power supply cable to the repeater.
• Network Connection: Attaching the primary I/O twisted-pair cable from a main hub to the primary port, and connecting other 10Base-T compatible devices to the remaining RJ45 ports.

It also details the function of the unit's seven green LED indicators (for power, network activity, and individual port status) and lists comprehensive specifications such as dimensions, power consumption (3.5W), operating environment (temperature and humidity), and compliance with FCC Class A, VDE Class B, and IEEE 802.3 standards. The document includes a section on optional cable types and RJ45 connector pinning.

Finally, the document contains important FCC notices regarding the device's compliance, potential radio frequency interference, and recommended troubleshooting steps. It also includes standard disclaimers, copyright information, and trademark acknowledgments.
