CHAPTER 1

GENERAL DESCRIPTION

INTRODUCTION

MICRO-AIDE’s family of Limited Distance Modem (LDM) products can be

used in a variety of data communications applications. The family consists of

the following products.

• LDM-1 standalone - a complete LDM (photographed on the cover page of

this manual).

• LDM-1 plug-in - functionally identical to the standalone version, it is a

printed circuit board (PCB) that is mounted within the LDM-16 nest.

• LDM-16 nest - a 19" rack-mounted chassis that can be equipped with 1 to

16 LDM-1 plug-in PCBs.

The LDM-1 can be thought of as a device for extending RS-232 communica-

tions over great distances (e.g., thousands of feet). It serves as an interface

between the customer’s Data Terminal Equipment (DTE) and data communi-

cations network. It is designed to be compatible with four-wire, private line

networks. It can be used to facilitate point-to-point and multi-drop network

configurations. Its unique performance characteristics permit data transmis-

sion and reception over distances of many miles. Additionally, the LDM-1 will

operate over a wide temperature range.
