Rs232 9 pin connector pinout.
The 9 pin de 9 connector has been used by most ibm compatible pcs since the serial parallel adapter option for the pc at where it allowed a serial and parallel port to fit on the same card.
The table below contains some rules of thumb from experiments done by texas instruments years ago.
This use has been standardized as tia 574.
Rs232c retains the features of rs232 but uses 25 pins rather than a 9 pin serial pinout.
The dte pc has the male connector shown below and the dce peripheral has the female.
Rs 232 maximum cable length.
Some miniaturized electronics particularly graphing calculators and hand held amateur and two way radio equipment have serial ports using a phone connector.
By using these configurations it means that an rs232 cable connecting a dte to a dce will be wired in a one to one configuration i e.
The dce and dte ports are exactly similar except for the direction of data flow.
This pinout can make a world of difference for successful rs232 serial communications.

The maximum cable length for rs 232 is 50ft but in practise depends on baud rate cable specific capacitance and ambient noise.
It defines the electrical properties and the timing of signals as well as the interpretation of signals and the physical size and pinout configuration of a 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.
