Sadly, I guess my electronics skills are no longer good as I'm not sure how to hook it up.

In case the picture doesn't come through, it has a teletype 152950 120 ma loop supply attached to a box that has a switch and terminal strip in it.

The red and black wires from this supply go to:

red to two large resistors in parallel

black to the terminal strip.

I'm thinking I need to take the output of the resistors and run it to the teletype and then take the output from the teletype and hook it to the black wire on the terminal strip which will complete the loop.

Is that correct?

Thanks,

Virgil
