[GreenKeys] Current Loop Converter

[Dave Hunter]

Hi All:

Does anyone have for sale a current loop to RS232 converter 
which is selectable between 20 or 60 ma loops?

Alternatively, can anyone recommend a commercial product 
which they use to drive an ASR-28 from a computer, also, to 
drive an ASR33 from the computer (future project)...

I realize these can be built, but as a diabetic with 
eyesight which is now beginning to give me problems, it 
will be simpler to purchase a suitable pre-wired device...

Dave, VY2AC
