[GreenKeys] AN/UGC-504, AN/UGC-136 Teletype Plug Wiring Solved

[Dave Hunter]

Hi All:

I am mentioning this on the list as several here have 
purchased these high speed military teletypes.

Those being sold, come without their power cables and 
connectors to fit the machine. Plugs are available, but so 
far, I haven't been able to come up with a manual to 
share...

Howevert, I have figured out the plug wiring as of this 
morning. The machine uses a Captor RFI filter, and by 
tracing back from its output to the plug (which is located 
in the Captor filter), I was able to trace out the AC path.

I have verified that B is one side of the AC line, and that 
C is ground, and A is the other side of the 120 vac line..

These alphabetical pin designations are printed on the back 
of the plug.

I made up a temporary connection using pins off a miniature 
octal tube plug, fit them on the correct pins, and now have 
it powering up. The machine powers up in an error state - 
perhaps because it isn't connected to a loop, or there may 
be another problem with the machine. If I get a chance 
later today, I will also try my other machine.
