[GreenKeys] RS-232 to Polar Relay

[John, W9DDD]

OK guys, I thought I had this all figured out at one point.  But, as I 
review things before cutting wires and soldering in new ones I find some 
confusion.  The drawing I can find in my emails archive shows jumping 
pins 2 and 7 together to put the polar relay coils in series.  But 2 and 
7 are one of the coils.

So is there another version of the drawing floating around? Perhaps in 
RTTY Journal archives?   The one I have is black lines on white back 
ground.  I thought someone had sent me a white line on black as well, 
but I can't find it in my email archives.  Can't in the on-line archives 
either. So either it was emailed direct and I accidentally deleted it, 
or I dreamed seeing it.
