#104723 - SBC RS232 Responding to: ???'s previous message |
The relevant part of 8052.com.SCB.schematics:
http://www.8052.com/sbc/schem...er_ico.gif left bottom part. I personally prefer the simpler schematics from the paulmon pages, it is simpler (although the DSub9 pinout is different - for the nullmodem style cable). Please note also the discussion on various variants of the "MAX232" and the related variety of required capacitors. Go for the variant which needs the 100nF (0.1uF) caps only. Jan Waclawek |
