Description
The Socket Radio is a complete embedded wireless modem. The Socket Radio accepts standard modem AT
commands and provides connect rates up to 30 kbps half-duplex. The Socket Radio provides numerous additional
features for embedded modem applications. This device is ideal for embedded modem applications due to its small
board space and low power consumption. The Socket Radio allows for rapid integration into existing modem
applications by providing a serial interface that can directly communicate to a microcontroller via a UART interface.
The development kit comes with a USB adapter that will appear as a serial port to the PC. This interface allows for
PC evaluation of the modem immediately upon power up via the AT commands using standard terminal software.
The Socket Radio is a bi-directional data communications radio to be used for two-way communication to another
Socket Radio. The radio emulates a standard Hayes compatible telephone modem in a socket modem physical
format. Each radio has a permanent unique Identification Number (ID). This allows multiple radios to coexist on the
same channel. The radios operate in a peer to peer switched network while providing the appearance of a switched
phone line network.

Host Interface
The serial interface on the 3.3V Socket Radio is not 5V tolerant.
The USER IO signals on the 3.3V Socket Radio are not 5V tolerant.
Socket Radio modems can be directly connected into 3.3 volt systems with 3.3 volt or 5 volt power supplies. The
default host speed of 19.2 Kb and 8N1 format (8 data bits, no parity bit and 1 stop bit). The defaults can be changes
after initialization by using standard AT commands. A true RS-232 interface is available on the Socket Radio
Evaluation Kit.
The Asynchronous Serial Interface is a complete UART consisting of Receive and Transmit signals as well as
RTS/CTS, control is supported.
The UART is programmable to support a number of baud rates and data formats. Supported data rates and formats
are:
Data Bits: 8
Stop Bits: 1
Parity Bits: None
Baud Rates: 9600, 19200, 38400, 57600, 115200

Mechanical
The modem module is on an 0.062 thick FR-4 PC board. The module has two rows of 2mm pins located 24mm on
center. The module is designed to plug into 2 mm sockets with the same 24 mm spacing. The modules can also be
ordered without the 2mm headers (N suffix).
Due to the low mass of the board, no retention is required aside from the sockets. A large tie-wrap may be used to
insure retention in high shock or vibration environments, if desired.
