Ok hw gurus, here’s your chance to help out a clueless sw guy:
I’m using this board essentially as a power supply and rs-232 converter for another circuit that I’ve built on the board.
Here’s the problem. The board doesn’t talk to the PC unless I put an RS-232 mini tester (w. leds for the serial lines) on the line. Then the RS-232 works and communicates with a PC. With no tester, it doesn’t work.
Any ideas? I am using the board in 3.3v mode (my circuit requires 3.3v).
No public wish lists :(
