AeroComm’s embedded transparent protocol simplifies the
OEM’s integration process by allowing for drop-in installation.
As each transceiver receives raw data, it manages over-the-
air protocol to assure successful communication. Headers,
data packet length, and CRCs are not needed.
RF232 supports simple cable-replacement to complex peer-
to-peer configurations. Broadcast communication to all trans-
ceivers or address packets to a specific destination using
unique MAC addresses embedded in each transceiver.
