Description
The low cost TMAS GSM Modem is ideal for a wide range of applications. The modem can be used to make
circuit switched data calls, making the unit suitable for remote dial-up systems where a fixed phone line is not
available. The SMS functionality enables the sending and receipt of text messages. A common use for this
functionality is an SMS server for the automated sending and receipt of bulk text messages.
The modem implements the highly reliable Siemens TC35i GSM Engine. This ensures high quality and reliable
operation along with compatibility with all standard GSM networks. The modem provides support for the
Siemens TC35i AT command list, also available for download from the RF Solutions website.
The TMAS modem is supplied in a rugged extruded aluminium enclosure making it suitable for use in a wide
range of industrial and demanding environments. The unit connects directly to a PC or terminal device via the
DB-9 RS232 Cable interface. The integral SIM card holder accepts standard SIM cards of all network operators.
The only other connections required are to 6-40Vdc power supply and Antenna (supplied separately).
