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

[Larry Tighe]

Here'e my guess on the AN/UGC 74 A/B/C......they are probably NATO 
compatible machinery so the plugs might be interchangeable.

Try for this:

J3 A battery back-up +
     B battery back-up -
     C ground

J2  E ground
  jump J/A &C,  B/D&L  (for 120 vac operation)
  M  AC OR +DC IN
  K  AC  OR -DC IN
(it appears that you jump as above pins and apply
the AC input to M and K)

J1 Data/Clock
A REC CLK HI
B REC CLK LO
D REC GATED CLK HI
E REC GATED CLK LO
P XMIT CLK HI
N XMIT CLK LO
H REC DATA LO
K XMIT DATA HI
S XMIT DATA LO
S SIGNAL RTN
T SHIELD GND
R TRANSFER
