. INTRODUCTION. INTRODUCTION

. INTRODUCTION

SHM-1 is a short-range modem whose operation is based on
RS-232 and RS-422 serial communication format.

The modem is connected between a controller (for example,
AXS-100 access control system) and a computer.

Using the modem enables data communication range of up to
1200 meters.

Few modems can be used to increase the communication range
in 1200 meters increments.
