Rs232 Cable Pinout. RS-232 defines both the physical and electrical characteristics of the interface. Each pin in a 9 or 25 serial connector pinout has its own distinct function.
These D-sub connectors can terminate with an RS232 female pinout or DB25 or DB9 male connector pins. Pinout of RS232 to RS422 cable and layout of 25 pin D-SUB male connector and 37 pin D-SUB male connectorelectrically isolated RS422 communication interface to the PC serial port. It formally defines signals connecting between a DTE data terminal equipment such as a computer terminal and a DCE data circuit-terminating equipment or data communication equipment such as a modemThe standard defines the electrical.
A computers serial COM port DTE is usually a male port as shown below and any peripheral devices you connect to this port usually has a female connector DCE.
These D-sub connectors can terminate with an RS232 female pinout or DB25 or DB9 male connector pins. RS232 Pinout Below is the pinout of a typical standard male 9-pin RS232 connector this connector type is also referred to as a DB9 connector. In a standard null modem cable pin 4 at one end of the cable will drive pins 1 and 6 at the other end. Each pin in a 9 or 25 serial connector pinout has its own distinct function.
