INTRODUCTION

I N T R O D U C T I O N

The ARCNET Active Hub is an electronic bi-directional repeater designed to expand the number of ARCNET nodes that can be used on a single network. A network node is any attached device that can participate in the token-passing process. Nodes can be drives, PLC gateways, remote display controllers, remote logic nodes, remote computers, etc.

The ARCNET Hub receives messages sent by any one transmitting node, and relays the message to all other nodes on the network. The ARCNET Hub has four ports. Each port can accommodate a cable segment containing up to eight (8) nodes. The ARCNET Hub also has LED indicators on the Hub card showing which port LAN segments are actively receiving. The ARCNET Hub card can be used in a separate power supply/card cage as a stand alone unit, or installed into a PLC gateway.
