Lexicon, Inc. DC-2/MC-1 Serial Communications Protocol Printed on: 10/19/00 The DC-2/MC-1 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 DC-2/MC-1. The DC-2/MC-1 Protocol is a 3 layered system. The DC-2/MC-1 serial protocol allows for the DC-2/MC-1, or the HOST to initiate a communication transaction. Most transactions are initiated by t
