RS232 Pinout | DB9 pinout

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. A computer's 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).

DB9 Pinout

The DTE (PC) has the male connector (shown below), and the DCE (peripheral) has the female. RS-232 Maximum Cable Length . The maximum cable length for RS-232 is 50ft, but in practise depends on baud rate, cable specific capacitance and ambient noise. The table below contains some rules-of-thumb from experiments done by Texas Instruments years ago.

RS232 pinouts and wiring

Again make a note of which LEDs are lit. If any single LED is lit by both of the devices, then there is an output conflict, and the cable wiring is incorrect. By this, I mean that one line in the cable has an output driving it from both ends - and this is not correct for RS232 - so that means that the cable wiring is not correct for the devices.
