2. Theory of Operation
2.1. General
The Wi.232FHSS module is one of a family of WiSE™ (Wireless Serial Engine) modules. A WiSE™
module combines a state-of-the-art FSK data transceiver and a high-performance protocol controller to
create a complete embedded wireless communications link in a small IC-style package.
The 250mW RF transceiver is built around the Analog Devices ADF7020 IC, whereas the 25mW version
uses the Semtech XE1203F transceiver IC. Both transceivers are designed with the components
necessary to facilitate operation in the 902-928MHz US ISM band.

The Wi.232FHSS module has a UART-type serial interface and contains special application software to
create a transparent UART-to-antenna wireless solution capable of direct wire replacement in most
embedded RS-232/422/485 applications.
Note: Although the module is capable of supporting the typical serial communications required by RS-232,
RS-422, and RS-485 networks, it is not compatible with the electrical interfaces for these types of
networks. The module has CMOS inputs and outputs and would require an appropriate converter for the
particular type of network it is connected to.
