I started to hook stuff up to my control box and ran across a problem. For some reason I don't get any signals through the breakout board. I did test the parallel port sorta by measuring the voltage to pins 2 3 4 etc by setting them as dir and changing it and measuring with a voltmeter. I was able to detect the + 4.3v vs .1v when I changed the dir. I also tested this through the db25 cable. But I can't get anything through the breakout board. Currently I am using a c10 board just to get everything started. So does anybody have any ideas? Also I'd like to know if anybody knows if it matters if you put +5vdc vs ground into the gecko 320x com.Click image for larger version.
