The MC-8 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-8. The MC-8 Protocol is a 3 layered system. The MC-8 serial protocol allows for the MC-8, or the HOST, to
initiate a communication transaction. Most transactions are initiated by the HOST. MC-8 then responds to the
HOST command with either a response or acknowledgment packet. There are a few asynchronous notifications that
MC-8 initiates indicating system changes. Each transaction initiated must wait for a corresponding response before
initiating the next transmission.
The 3 protocol layers are: Physical, Data Link, and Application Layers.
The MC-8 Serial Protocol attempts to be as backward compatible with the MC-1 as possible. The basic structure of
the protocol has not changed.
