ok, my garmin etrex gps ... only uses TX and RX ... http://home.cdsnet.net/~purple/projects/g45contr/ePlug/assembly.jpg shows the connections...
since I get power, Elsewere... the question IS.. do I Need to power VCC on CN12 .. in order to send power to my MAX chip? or, do the two lines I need, Work, running thru this chip without any power ? ( sorry, Clueless here..)
now, I would Love, to hookup all the lines necessary for a 'normal' com port.. (to use an IR remote... ) but, for Now, I'm willing to just get my GPS going..
I guess, I just Don't understand, why, in Perfect's drawing... there Isn't a line connecting VCC ... all the connected lines make sense to me, (well, mostly, :) ) thanks!
