Several Ways to Connect DB9 to RS232 and RS485：For RS232 , connect to pins 2, 3, and 5. Pin 2 is Receive (RX), Pin 3 is Transmit (TX), and Pin 5 is Ground (GND). The other pins do not need to be connected. For RS485 , connection is usually made to pins 1 & 2 or 3 & 8. RS485 uses differential signals, so there is no distinction between receive and transmit. Typically, the connections are Pin 3 (+), Pin 8 (-), Pin 1 (+), and Pin 2 (-). Tool-Free, Solderless Installation – Skip the hassle of soldering with our user-friendly design.
