CHAPTER 1 INTORDUCTION

Product Introduction

EH-500, EH-800A and EH-1600 is a standard Ethernet
concentrator that re-times and re-transmits the signal to each
network station on the LAN. It simplifies the implementation of
twisted-pair Ethernet compatible networks following the IEEE

802.3 10Base-2/5/T CSMA/CD standard. Each Hub has 5/8/16
modular RJ-45 STP ports and one BNC port; EH-1600 also have
an AUI port for attaching network devices (file server, bridge,
and workstations) or additional concentrators.

Product Features

EH-500/EH-800A/EH-1600 provides all the functions necessary
to support the requirements of Ethernet networks. These function
includes the following features:

♦ 5/8/16-port STP RJ-45 connector and one port BNC, one port

AUI(EH-1600).

♦ Manchester decoder for clock and data recovery
♦ Automatic preamble regeneration to compensate for any bit

loss

♦ Lockup and auto-partition for jabber to isolate network

failures

♦ Auto-Polarity correction
♦ LEDs for Power, Collision, and Link, TX/RX per port
♦ Desktop or wall-mountable(EH-500/EH-800A).
