ABSTRACT:
A communication network digital message format is provided in which on message start signal has a logic "1" value for two bit intervals to provide improved noise immunity in transmission of a message over a network medium. The start signal is followed by a control bit one logic value of which designates a plurality of message bits as instruction bits to enable an interface to be set up between the network and a microcomputer, the other logic value of said control bit designating a plurality of message bits as data bits for the microcomputer after said interface has been established.
