  To set a modem to answer after 2 rings: ATS0=2    Save this with AT&W  
For technical reasons, a Telstra SIM card is recommended for use in Australia, with a "Data" number.
There are two kinds of 'phone numbers: Voice, and Data.
To be able to receive data calls on the GSM modem you need a "Data" number.
With a Voice number, outward data calls can be made, but the GSM modem will not answer incoming data calls.

GSM modems can be dialled up (and data transmitted) from a normal modem on a land line, provided that the SIM cards are data enabled.

If you are having modem problems, output the active profile (current settings) using AT&V.  Email this to us (see top of page),
or print and fax it to Esis Pty Ltd, fax 02 9481 7420.

GPRS (General Packet Radio Service)
These GSM modems have GPRS capability. Subscribers log in and remain online.
User pays for the actual data transmitted, not for the time connected.
Its packet structure corresponds to the IP protocol. GPRS helps transmit large amounts of data in a very short time via mobile access.
Applications such as mobile Internet, fast e-mail transmission and e-commerce now make real economic sense.
With GPRS, when the modem connects, the network generally allocates an IP address dynamically to the modem, which is then used until it disconnects.
For GPRS the networks charge according to data packets sent, not according to how long the modem is connected.

RoHS is the acronym for Restriction of Hazardous Substances - EU Directive 2002/95/EC: restriction on the use of certain hazardous substances in electrical or electronic equipment sold or used in the European Union after July 1, 2006. These hazardous substances include: lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls, and polybrominated diphenyl ethers.

ETM9200 - see ETM9300   The ETM9200 is replaced by the ETM9300

ETM9300 GSM Modems

The ETM9300 dual band GSM/GPRS modem is capable of transmitting
data, short messages (SMS), and fax messages via the GSM/GPRS mobile network.
It utilises the GSM/GPRS network for convenient and inexpensive data transfer
from remote instruments, meters, computers or control systems.
The terminal is capable of GPRS class 8 and 10.

ETM9300 uses a new engine - the Siemens dual band MC39i (instead of the MC35i).
The new engine meets RoHS regulations (see above in green).
Dim: 93 x 52 x 25 mm (ETM9200 was 93 x 52 x 20 mm).
ETM9300, with the MC39i engine, is also capable of class 10 GPRS and hence requires larger capacitors.
SIM Card Holder now has Sliding Cover - more robust, and longer lasting.
The LED is now visible in all possible mounting positions.
Mounting Holes are counter sunk in both directions giving more mounting options.
Power requirement: 6-35 V DC, 300mA @ 12V   (ETM9200 was 6-40 V DC, 190mA @ 12V)
GPRS capabilities: GPRS class 8 and GPRS class 10 (was GPRS class 8 only) on a single module.
The ETM9300 can also be locked into operating at class 8 GPRS using an AT command,
     so as to maintain similar power consumption to the ETM9200.

This dual band GSM / GPRS modem is ideal for communication of data, fax or SMS messages via the GSM mobile network
