FLEXIBLE RF PROTOCOL
Laird Technologies’ embedded transparent protocol simplifies 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. Broadcast communication to all devices or address packets to a specific destination using unique MAC addresses embedded in each
unit.
