Lexicon MC-12HD Serial Communications Protocol
The MC-12HD uses simple notification, command, response and acknowledgment packets to have
communication transactions with a given HOST. This protocol is designed for point to point
communication between a HOST and MC-12HD. The MC-12HD Protocol is a 3 layered system. The MC-
12HD serial protocol allows for the MC-12HD, or the HOST, to initiate a communication transaction. Most
transactions are initiated by the HOST. MC-12HD then responds to the HOST command with either a
response or acknowledgment packet. There are a few asynchronous notifications that MC-12HD initiates
indicating system changes. After each transaction is initiated, the initiating device must wait for a
corresponding response before initiating the next transmission.
The 3 protocol layers are Physical, Data Link, and Application Layers.
