Yikes, please delete that pastebin link. That was just my initial try at a FAQ.  A significantly updated and more current version of the FE-5680A FAQ is located at http://www.ko4bb.com/dokuwiki/doku.php?id=precision_timing:fe5860a_faq

Scott's utility seems to be able to dump the FEI unit serial number, and perhaps the included options.  If my guess is correct, all three of the units I have are equipped only with "Option 2" which is the RS-232 port.  But there are many possible varieties of 5680 units out there, and some of them may have the 1 PPS behavior you mention while others do not- I have no information on that.
