Some help needed - light pen connector on monitor

2008-06-03 by dvdborn

I'm still trying to find out how I need to connect my light pen back to the monitor on a IIx.

If someone could tell me which voltages they measure on the connections points of the light 
pen connector on the monitor, I can figure out how to connect them.

Would anyone be so kind to measure this for me?

There are 4 pins that should output some voltages. Two pins should read about +1,94V, and 
one is +5V and the other one is -0,01 volt. I used the ground connector on the inside of the 
panel of the Mainframe unit as my other connection point while measuring.
