Chapter One INTRODUCTION
This user manual outlines the features, mounting, operating parameters, connection, safe use and
configuration of the 605M-D1 modem. When used in conjunction with the ELPRO 605M-R1 Router, the user
manual for the 605M-R1 must be consulted prior to configuration and commissioning. Failure to consult with
the 605M-R1 manual may result in the warranty being voided.
The ELPRO 605M-D1 is a GSM Mobile Stations (MS class B) device capable of using GSM Circuit Switched
Data (CSD), Fax and Short Message Services (SMS) communications and output. The 605M-D1 is a quad
band, GPRS device communicating at GSM-850 / EGSM-900 / DCS-1800 / PCS-1900 MHz, Class 10 GPRS
data packet transfer. It has an embedded TCP/IP stack and DNS query protocol supporting static and dynamic
IP address allocation, PPP, UDP and FTP functionality.
Programming of the 605M-D1 modem in use is either via the ELPRO provided configuration utility, or via AT
Commands (GSM 07.07 and 07.05) listed later in this user manual. Connection to the host controller (Data
Terminal Equipment DTE) is established through one RS232 standard port which also performs serial bi-
directional Data and Fax transfer. Use of the 605M-D1 will require third party products and/or services such as
telecommunications access.
The 605M-D1 AT command set listed later in this manual also features:
Network quality Detection - allowing scanning of all GSM (without SIM) channels to ascertain which provider
has the best signal, most channels and/or transceiver base stations in optimizing service provision.
Jam Detect and Reporting - reporting attempts at interfering with the GSM radio signal (reported as an
unsolicited message on the RS232 port).
