AC4490-1X1
900MHz Radio Module
FLEXIBLE RF PROTOCOL
Laird Technologies’ embedded transparent protocol simplifies the OEM’s integration process by providing
drop-in design. 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 configurations, broadcast communication to all radio
modules or address packets to a specific destination using unique MAC addresses embedded in
each radio module.
