The GXR-GPRS Modem, now a legacy product, was a simple, but powerful tool for wireless connection of GeoSIG instruments via the RS-232 port to the Internet, thus to any remote computer.
This device acted like an ordinary modem, controlled by AT commands.
The unit was delivered with all necessary accessories, and peripheral units such as the cabling, connectors, antenna, etc as well as firmware & software, thus was ready to use out of the box together with the associated GeoSIG Instrument.
