Bill,
I have the KS-24361 units. This may also work with yours.
When I connect a terminal to the J6 1PPS connector I see data similar to
yours. This is sending the time.
Here is an example from my unit:

Have the subject RFTG unit. Bought an RS-422 to USB converter, found a
simple terminal emulator (PuTTY), and scoured KO4BB's site.
Discovered that the pins for the otherwise unlabeled "RFTG-m RS-422
INTERFACE" drawing were reversed, and that you don't connect R to R and
T to T. The diagnostic softw
Hi All;
I'll give my experiences with my RFTG unit. I bought it ($$$) last fall from an
ebay seller who moves a lot of time and frequency related items, it won't take
much imagination to figure out who I'm speaking of. I believe he is an honest
seller, and I've bought from him several times and

Very nice pictures!

I have an FRS-C rubidium (10 MHz) that I bought a couple years ago. It
came in a metal box that also contained a circuit board that provided 3
TNC output connectors. Tw

Nope, haven't fired it up yet. I'm not sure when that will actually
happen; too many projects going on in the basement! I wanted to get the
pics up to assist anyone else who may be working out the interface

John,
Nice pics!
Did you at least run it to see if it works and what kind of performance
you could get out of it?

My RFTG-m-XO arrived today, and the first thing I had to do was rip it

disassembly at http://www.febo.com/time-freq/hardware/Lucent_GPSDO/.
