Short Message Services –
The SocketModem CDMA offers SMS features such as mobile
originated, mobile terminated, cell broadcast, Over the Air Activation (OTA), OTASP, and OTAPA.
Management Features –
The SocketModem CDMA provides advanced management features that
include: phone book management, fixed dialing number, real time clock, and alarm management.
Industry-standard Modem Commands –
The SocketModem CDMA provides industry-standard AT-
style commands for ease of integration into your existing software application.
SocketModem Pin-Out –
The SocketModem CDMA 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 230K bps and can be interfaced directly to a UART or microcontroller.
