Feature Details
Integration Reduces Space, Power, and Cost –
The SocketModem
CDMA integrates the controller,
RF transceiver, and antenna interface in one module. This integration requires low power and low
real estate, and it 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 –

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.
