    Thanks for the explaination. The numbers are much easier for me to
understand. What I'm trying to work with is the sensor in my garage and the
computer 30' away in the house. The 6-pole LP  in the house is to eliminate the
noise in the shielded wire. Is there an optimum load resistor in the house
which I should use to minimize noise from the low
current?  I currently (no pun intended) use a 20-30k load resistor on the cable
end  in the house.
Regards
Barry
