Introduction

INTRODUCTION

Your Telenetics 2185 is a digital bridge that can connect up to five sub-
channel devices to a single main channel device. Sharing computer and
communications resources through a 2185 can achieve significant sav-
ings in hardware and line costs.

The 2185 is a versatile unit that can be used in both port-sharing and
modem-sharing applications. The main channel and each of the five
subchannels are individually configurable as either EIA 232-D Data
Terminal Equipment (DTE) or Data Circuit-terminating Equipment
(DCE).

Data received on the main channel is broadcast simultaneously to the
subchannels. Subchannels contend for one-at-a-time access to the main
channel.

2185 FEATURES

To ensure trouble-free operation and allow for network growth you
2185 has a number of impressive built-in features including subchannel
contention, anti-streaming, and a synchronous data retiming buffer.

Data Interface

To virtually guarantee you are able to connect your equipment to the
2185, all data interfaces (main channel and five subchannels) are EIA
232-D compatible. They can be individually configured as DTE or DCE
via front-panel-mounted DIP switches. All connections to the 2185 are
made via straight-through cables.
