Note 1:- Pin 8 and Pin 20 - External GPS input is selected using a menu function or set during programming when the software option required is fitted.
Note 2:- 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/
