1. INTRODUCTION
The Polygon Technologies GSM Commander is a state-of-the-art, highly configurable and
versatile SMS controller. It contains a quad-band integrated GSM cellular engine that allows it
to connect to any cellular network to send and receive SMS messages. The GSM
Commander can be used to monitor inputs, measure analogue voltages, and remotely control
outputs. The GSM Commander is configured using a software program that provides an easy
wizard interface. The GSM Commander connects to a PC via USB for configuration, after
which it may be disconnected from the PC for standalone operation. Some setup operations
can also be performed by sending simple SMS messages.

if YES, the unit is able to recognize (and respond to) key presses on a remote phone during
a voice call.
If Single, the unit has only a single SIMcard slot. If the SIMcard in that slot becomes faulty
or the associated network goes down, the unit loses communication ability. If Dual, the unit
can switch over to a secondary SIMcard if it detects problems on the primary SIMcard, thus
greatly enhancing reliability.
