This bit sequence and its complement must not be found in the sequence preamble and ID word. Data must follow the Header without any delay. Data are completed by a End-of-Message (EOM) word, consisting of 2 NRZ consecutive ones or zeroes. Even in case of FSK modulation, the data must be completed by a EOM and not by simply stopping the RF telegram. If the complement of the Header word is received, output data are complemented too. The following example shows a complete message with Preamble, ID, Header words followed by 2 data bits, and an EOM. The preamble is placed at the beginning of both ID and Header words.
