Rs232 9 Pinout

Rs232c retains the features of rs232 but uses 25 pins rather than a 9 pin serial pinout.

Rs232 9 pinout.

Rs232 serial port monitoring hardware stands out for a number of reasons including its 9 pin rs232 pinout. D sub 9 connector pinout. Pinout of pc serial port rs 232 de9 and layout of 9 pin d sub male connector and 10 pin idc male connectorthis rs232c de 9 usually miscalled db 9 port is available in some pcs and many other devices. Of course i jest the 25 pin rs232 connector is mearly legacy from the early days of rs232.

When developing or troubleshooting systems using rs 232 close examination of hardware signals can be important to find problems. This pinout can make a world of difference for successful rs232 serial communications. A serial pinout diagram is presented below. The rs232 protocol uses a 9 pin serial port that can have either male or female connectors.

Standard is the default serial port pinout for serial communications with partial handshaking. These nine pins are arranged in the port as shown in rs232 connector pinout. One is a data terminal equipment dce and the other is known as the data terminal equipment dte. The dce and dte ports are exactly similar except for the direction of data flow.

The most recent version of the protocol is known as rs232c. I guess they felt like giving the data lines a bit more room to stretch out perhaps it s the rs232 pinouts equivalent of flying first class. 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. Standard rs 232 null modem pinout preset scheme.

Thus it is important to understand how the 9 pin rs232 cable pinout can affect the flow of serial data between devices. You can see the rs232 serial port pinout numbers are different for the 9 pin and the 25 pin type connections. Although the rs232 standard does not define a connector the 9 way and 25 way d type connectors are very popular and provide an excellent format.
