QUICKLINK

A Line of External Fixed-Port Active Hubs for ARCNET® Local Area Networks

INSTALLATION GUIDE

INTRODUCTION

The QuickLink (QL) Series of external fixed port hubs provides a low cost

method of expanding ARCNET local area networks. These eight-port hubs

provide the ultimate in reliability and flexibility for cabling ARCNET

networks. A hub allows for the addition of a segment and support for

distributed star topologies. The QL utilizes the same robust hub timing

electronics found in the Contemporary Controls (CC) MODHUB series for

modular active hubs. This includes precision delay line timing, digitally

controlled timers for dependable operation and reduced bit jitter. Also, a

watchdog timer is included to prevent hub lockup — eliminating the need

to recycle hub power in the event of extraordinary electrical disturbance.

The QL operates from low-voltage AC, requiring a power voltage source in

the range of 8 to 24 volts.

Active hubs increase the robustness of ARCNET networks. They maximize

the distance that can be achieved on each cable segment ⎯ up to 2000 feet

(610 m) feet on coaxial segments. They prevent interference to the network

by squelching reflections caused by open or shorted cable segments attached

to the hub. Unused hub ports need not be terminated. Active hubs allow for

a distributed star topology, thereby minimizing the cabling required in a

facility. Two or more QL hubs may be cascaded.
