  1. The 25-pin RS-232 pinout includes the following connections:
    1. Pin 1: GND (Shield Ground)
    2. Pin 2: TxD (Transmitted Data)
    3. Pin 3: RxD (Received Data)
    4. Pin 4: RTS (Request to Send)For a loopback test with no hardware flow control, connect pins 2 to 3 for RS-2321. For RS-422/485, connect pins 5 to 20 and 7 to 222.

    Most of the pins on DB-25 connectors are not connected since only nine pins are used for RS-232, RS-422, and RS-485 communication. To perform a loopback test with no hardware flow control with a DB-25 connector, connect pins 2 to 3 for RS-232. For RS-422/485 connect pins 5 to 20 and 7 to 22.
