Feature Details
Integration Reduces Space, Power, and Cost – The SocketModem GSM/GPRS integrates the
controller, RF transceiver, and antenna interface in one module. This integration requires low power,
low real estate and provides an overall reduction in costs.
Reduces Development Time – The SocketModem GSM/GPRS can make your existing and next
generation device, machine, or system, communication-ready without requiring significant hardware
changes to its design. This complete, ready-to-integrate wireless SocketModem allows you to
enhance your product while you focus on developing its core features.
Short Message Services – The SocketModem GSM/GPRS offers SMS features such as text and
PDU, point-to-point (MT/MO) and cell broadcast.
Management Features – The SocketModem GSM/GPRS provides advanced management features
that include: phone book management, fixed dialing number, real time clock and alarm management.
Industry-standard Modem Commands – The SocketModem GSM/GPRS provides industry-
standard AT-style commands for ease of integration into your existing software application.
SocketModem Pin-Out – The SocketModem GSM/GPRS interfaces easily with existing products
through a standard serial communication channel. The complete on-board RF transceiver interfaces
with an antenna for direct connection to wireless SMS, circuit-switched dial-up, or packet data
networks. The SocketModem also includes an onboard LED to display network status. The
SocketModem is a Data Terminal Equipment (DTE) device with serial asynchronous protocol support.
The serial DTE channel is capable of transfer speeds to 115.2K bps and can be interfaced directly to
a UART or microcontroller.
