FLEXIBLE RF PROTOCOL
Laird Technologies’ embedded transparent protocol simplies the integration process by allowing seamless plug-and-play installation. As each unit receives raw
data, it manages over-the-air protocol to assure successful communication. Headers, data packet length, and CRCs are not required. RF232 supports simple
cable-replacement up to complex peer-to-peer setups. Broadcast communication to all devices or address packets to a specic destination using unique MAC
addresses embedded in each unit.
