Hi Guys,
I have my complete USB to RS232 circuit design complete, built and tested. Problem I am having with it though is that transmit from the PC does not work properly, comes across as the wrong key. The RX piece back to the computer works perfectly. Attached is the circuit diagram. I really appreciate any suggestions as I am on a tight deadline to get this fixed. Thank you!
