ETM Pacific has introduced an updated version of its dual band GSM modem for convenient and inexpensive data transfer from remote instruments, meters, computers or control systems via the GSM mobile network.
The new modem is capable of transmitting data, short messages (SMS) and fax messages via the GSM mobile network. The unit communicates with the remote device via an RS232 interface.
Compatible with the AT-Hayes command set, the unit communicates at baud rates of 300 to 115200 bits/second through the RS232 serial link, however, due to limitations by the GSM network, the modem supports baud rates to 14400bps.
Installation is a simple four step process:
1. Connect to the remote device via the RS232 serial link.
2. Fit a standard FME antenna.
3. Install a SIM card.
4. Connect the power supply (the unit accepts a broad range of voltages from 6-40V dc, with a low power consumption of 190mA/12V dc).
Light weight and packaged in a robust ABS casing, the ETM9200 module can withstand extreme temperatures and shock and may be installed on many types of equipment in almost any environment.
A clearly visible green LED displays the operating status of the modem.
The ETM9200 is ideal for locations where the costs of providing fixed telephone lines might be prohibitive, or the application is mobile.
Evaluation software tools, including a signal strength facility together with ETM Pacific's technical support, enables designers to realise easy to implement solutions to complex problems.
