DB-9F null modem

2 layer board of 0.65 x 0.60 inches (16.5 x 15.3 mm).
Shared on January 29th, 2014 23:45

RS-232 null modem adapter board.

Edge-solder two DB9F connectors on either side of the board (DigiKey 4209FE-ND, for instance) and you get an RS-232 null modem. The pinout:

  • TXD<->RXD
  • RTS<->CTS
  • GND<->GND
  • DTR->DSR+DCD (x2)
  • RI->nc (x2)
