The
GD-01 modem provides RS-232/V.24 up to 9 600 bit/s connections
over GSM networks. It can be used instead of serial cable
to link PLCís, data loggers, security and surveillance
system or for data acquisition. It is possibility to
have an external signal (DTR) to trigger the modem to
call a pre-set number. This makes it ideal for alarm
monitoring and remote diagnostics from unmanned stations.
It is also possible to send/receive SMS-messages up to
160 characters as well as fax functions. It can communicate
with other GSM-modems but also traditional analogue modem
such as TD-32 or ISDN-adapters like ID-90. All configuration
is made by AT-commands similar to standard analogue PSTN
modems. The GS-01 uses the standardised GSM network on
900/1 800 MHz. This makes it possible for world wide
use (not U.S.A.). The housing is profiled aluminium and
has been designed to be easy to use and simple to install.
