Note1:-
These outputs provide channel information for use with antenna select units such as the BARRETT 916. The outputs are octal coded 0
to FF representing the least significant digit of the channel number selected. i.e. octal 0 for channel 1, octal 1 for channels 2, octal 3 for
channels 2, to octal FF for channel 16.
