GSM Automatic Voice Dialer
INSTALLATION AND OPERATION
MANUAL
INTRODUCTION
The E-AVDS-GSM GSM Automatic Voice Dialer is used to send voice or text GSM or SMS alert messages from an ENVIROMUX
Enterprise Environment Monitoring System (SYSTEM) to any user’s cell phone or device capable of receiving voice or SMS
messages. Before connecting the E-AVDS-GSM to the SYSTEM, a GSM SIM card configured for GSM voice messaging and SMS
messaging must be installed in the E-AVDS-GSM following instructions below.
The E-AVDS-GSM-
P
includes a 12VDC power supply for connection to E-MINI-LXO or any other SYSTEM where an external power
supply will be needed.
Cell phone Mini SIM card for GSM modem
A SIM card or
Subscriber Identity Module
is a portable memory chip used in some models of cellular telephones. It can be thought of
as a mini hard disk that automatically activates the phone (or in this case the E-AVDS-GSM ) into which it is inserted.
SIM cards are available in three standard sizes. The first is the size of a credit card (85.60 mm × 53.98 mm x 0.76 mm). The next,
“standard” size is a miniature-version with a width of 25 mm, a height of 15 mm, and a thickness of 0.76 mm. Finally, the “micro”
version measures 15 mm x 12 mm x 0.76 mm. The E-AVDS-GSM accepts the mini SIM card.
Verify with your service provider that their Mini SIM card will work with GSM / 3G GSM type modems before purchasing their Mini SIM
card.
Note: Make sure the Mini SIM card is for GSM communication (not CDMA), configured to send GSM voice and SMS
messages, and that it is not locked (some SIM cards are "locked" to search for a specific IMEI number of the phone to
operate).
OPEN THE E-AVDS-GSM
There are four tabs that hold the case together. Two on the top side, and two on the bottom side. To open the case for Mini SIM card
installation, press down firmly on the seam of the case near the tabs on one side of the case and snap the case halves apart.
