2.4GHz Radio Module
AC4424
THE FASTEST WAY TO WIRELESS
Laird Technologies’ AC4424 is a 2.4GHz FHSS digital radio module that represents a
breakthrough in industrial RF communication. Comprised of a complete, agency-certified
radio and sophisticated RF232
®
protocol, the AC4424 simplifies the OEM’s design effort
and assures successful field operation.
The RF232 protocol makes the AC4424 a drop-in solution for seamless integration, easy
operation, and fast time-to-market. It manages all aspects of the over-the-air radio protocol
to assure successful transmission, so users are not concerned with the intricacies of headers,
data packet length, and CRCs. The entire radio connection is transparent to the OEM.
AC4424 modules are socket-compatible with Laird Technologies’ 900MHz AC4490 radio
modules, enabling OEMs to design once and subsequently interchange radios to
accommodate new markets, regulations, and environments*. Developer tools and
technical support make wireless integration fast and trouble free. Let Laird Technologies
help you find the best fit for your application.
* Although AC4424s will not talk to AC4490s, socket-compatibility allows for seamlessly interchanging the modules network-wide.

FLEXIBLE RF PROTOCOL
Laird Technologies’ embedded transparent protocol simplifies the OEM’s integration process by utilizing drop-in installation. As each
radio module receives raw data, it manages the over-the-air protocol to assure successful communication. Headers, data packet length,
and CRCs are not required. The RF232 supports simple cable-replacement to complex peer-to-peer configuration. It allows you to
broadcast to all radio modules or address packets to a specific destination using unique MAC addresses embedded in each module.
