INTRODUCTION

This document provides instructions for installing and removing
expansion modules to be used in the MOD HUB series of
modular ARCNET active hubs. More detailed information
regarding the MOD HUB Series can be obtained by referring to
Contemporary Controls’ MOD HUB Series User Manual.

CABLING CONSIDERATIONS

The MOD HUB Series is a line of modular active hubs for
ARCNET local area networks. These hubs support several
cabling types including coaxial, twisted-pair and glass fiber
optics.

As far as topology is concerned, each MOD HUB expansion
module is designed for use in star or distributed star
configurations. Expansion modules can be used to extend the
length of coaxial and twisted-pair bus segments by connecting
the expansion module at the end of bus segments.

The cabling types supported by the MOD HUB Series are listed
on the following page with their corresponding model numbers.
