Hi, are you using a DB9 female connector or a male connector? ... I'm wondering if connecting the cable to pin 3 of DB9 female is correct instead of pin2? thanks Payam Soltany said:

http://www.arcelect.com/rs232.htm As that page cited by Payam says, the pin-definitions and whether to use Male or Female depend on whether you are making a DCE or a DTE. See here for details: http://www.8052.com/forum/read.phtml?id=60533 And remember, ALWAYS check any other advice against the specs! http://www.8052.com/forum/read.phtml?id=85374 |
