[GreenKeys] RS-232 to Polar Relay

[til128 at juno.com]

If Jack didn't put one there, it didn't need one. LOL FWIW, I have been running one like that for about 10-12 years 24/7 with no problems. TT

John, A while back someone (and I cannot remember whom, because he deserves the credit.) Mentioned that a polar relay can be driven directly by an RS-232 output. Think about it, it is really a polar signal. I am kicking myself because I never thought of something so obvious.
