Innovative Technology
for a Connected World
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 its 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 configurations, broadcast
communication to all radio modules or address packets to a specific destination using unique MAC addresses embedded in
each radio module.

*The 900MHz frequency band is approved in the Americas and Australia as an unlicensed spectrum subject to
approval by device.
**For products and specifications suited to non-U.S. countries (e.g. Australia and Europe), please contact Laird
Technologies directly.
†Although AC4490 radios will not talk to AC4424 radios, socket-compatibility allows for interchanging the
modules network-wide.
††Current consumption assumes 50% transmitter on-time.
