No, it isn't the same, sadly - it would have been too easy.
There are only two connectors on the unit, one the one I
have been doping out, and the other, J2 which looks like an
RS-232 female connector. Of course, there remain two pins 
on the  J1 connector which I haven't doped out, too.

I have a number of queries out right now to places like the
Kindgston Military Communication Museum, various Teletype
and Cypher technician and military Sigs.sites and clubs,
etc. which I hope will eventually pan out with a manual for
these, but it is taking forever!

If I do get my hands on a manual for them, I will PDF it 
and make it available as there are more and more of both 
the canadian and US versions (AN/UGC-504, AN/UGC-136
inclusively) of these making their way onto the market now.

Some interesting things I have learned so far about these
machines so far are non-technical, but here in Canada, they
were used as part of the fire control systems, where high
speed and accurate communications were a "must", and that
there were two courses held here in Canada on them - one of
the major ones held at Kingston (Candadian Forces School of
Communications and Electronics Engineering) led by Ivan
Trudel, and the other at Camp Bordon. Another course was
held in Miami to train the course instructors... So bits 
and pieces are coming in via those means, but hopefully it 
will result eventually in more technical information on the
teletypes themselves.

Another thing that could be a problem is the availability 
of ribbon cartridges for the units. I have temporarily 
dealt with that problem by wetting the ribbon with WD-40 to 
make the ink flow. I have put a photo of the cartridge on 
the page today which shows the cartridge. I only found one
number on them, and that is "6017138" found on one of the
two ribbons in the machines. Now, I am sure that there is a
substitute, and even more certain that the military in both
of our fine countries still has a stock of ribbon for these
machines. Sadly, they will be sold off in an auction
somewhere, and we will never see them! The cartridge is in
the bottom photo:

If anyone has seen a printer using s similar ribbon, ket me 
know, and I will try to track down a source.

All fun!

Dave
