RS232 Pin Configuration New RS232 has nine pins as mentioned earlier. These nine pins are arranged in the port as shown inRS232 Connector Pinout. The DCE and DTE ports are exactly similar except for the direction of data flow. These nine pins are roughly divided in to three categories and...
9 pin RS-232 pinout So here is a simplified version of the serial connection pinout used on personal computers: the RS-232 9 pin pinout. Pin 1: DCD ← Data Carrier Detect Pin 2: RxD ← Receive Data Pin 3: TxD → Transmit Data Pin 4: DTR → Data Terminal Ready Pin 5: 0V/COM...
After all, that is exactly what the RS/232 specification is designed for. Quite simply, a "straight through" cable, linking pin 1 on the DTE connector to pin 1 on the DCE connector (etc.) is all that is required. Therefore, if you are using a DB25 connector, Pin 2 (TX) which ...
Personal computer manufacturers replaced the DB-25M connector with the smaller DE-9M connector. This connector, with a different pinout, is prevalent for personal computers and associated devices. Presence of a 25-pin D-sub connector does not necessarily indicate an RS-232-C compliant interface. ...
