Additional info: I was ignoring the "sixteen" you mentioned because I know Pronto Hex can be imported for use on a Harmony remote, and I don't recall what format might be consistently sixteen sets of four hex characters. Pronto Hex is sometimes sixteen sets of four, but more often much longer.
I found your other thread[Link: forums.logitech.com]
where I see two people are very insistent on the "sixteen". I don't know if they are correct. Maybe if I saw some samples of the format they want I'd recognize it.
In that other thread you also posted

Which is Pronto Hex for the Discrete power off for a Sony DVD. In a more concise notation it is device 80, command 47 from this list:[Link: hifi-remote.com]
Are you also trying to control that device? Or was that just posted as a sample of Pronto Hex to ask how to use Pronto Hex for a Harmony? Pronto Hex is the form generated by MakeHex. I know Pronto Hex can be used for a Harmony. I don't know how you do that nor whether that needs software that the support team keeps only for their own use.
