I confess! I, too, could not resist the opportunity to 'commune' with the members of the list with these Rb units.
I ordered two of the FE-5680A units ($36 ea. including shipping) from the same supplier with amazing speed (order date 1/4, arrival date 1/9 to NW Florida). They were marked 'FE-5680A UN 70021' 'S/N 0405-72179' and 'FE-5680A UN 71920' 'S/N 0413-75933'. I promptly came home, constructed a DB9 female connector, with the connections as specified in recent postings, and both units were up and locked with extremely close agreement with my TBolt and Z3816A in under 5 minutes. Pin 6 had a 1 uSec wide, 5 Volt, 1 PPS, pulse. I did not explore pins 8 or 9, the RS232 pins. I guess I'll have to go back through the list to see what, exactly, I can do with these. They, too, were packed with bubble wrap individually and then together, and in a plain envelope that was placed in a UPS plastic envelope. However, they arrived without damage, and, amazingly, very promptly. Not sure what, exactly, I will do with them yet, but they will certainly have many possible roles.

First, I was amazed at the speed at which I received these units. The order was placed last Friday, the shipment went out late Saturday and I received them today (Tuesday). In my experience, it has always taken two weeks or more to receive anything from China. I couldn't believe I got these in just three days. BTW, I paid $38 each with the free shipping. An outstanding deal IMO. I also received the semi-useless freebies. My only quibble so far is that both units were packed in nothing more than a large envelope, with a thin layer of bubble wrap added. Nothing is dented or rattling around, so hopefully they are OK. I'm just about to wire up a cable and power them on, so I'll know soon. The units I got have numbers of UN 71xxx and UN 78xxx. I don't know exactly what this means, but according to the ebay sellers, they are claiming that 6xxxx and 7xxxx numbers indicate newer units. Can anyone decipher this number sequence?
