 From Jack Hart:

Here's the pinouts for the hookup of the UGC-129(*).

J102
1    tx loop +
2    tx loop -
3    rx low +
4    rxlow return
11    rx loop +
12    rxloop -
13    txlow +
14    txlow return

J100 (power)
A    115VAC
B    115VAC
H    +28VDC
G    -28VDC return
E safety ground

I removed one of the unusable connectors (J101) and wired
right to the AC filter inside the machine for the AC
power cord. I used paperclip "pins" with teflon insulation for the data
connections. You jumper the tx loop + to the rx loop - to put the printer a
nd keyboard in series. This hookup worked for both of my 129's.
