AC4486
868MHz Radio Module
FLEXIBLE RF PROTOCOL
Laird Technologies’ embedded transparent protocol simplies 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 congurations; and broadcast
communication to all radio modules or address packets to a specic destination using unique MAC addresses embedded in
each radio module.
