Which is pin no4 in RS232 DB 9 connector?
RS232 uses serial communication protocol where data exchange is done bit by bit. Although RS232 is later replaced by faster USB (Universal Serial Bus) it is still popular in some areas. RS232 used to have 25 pin, now it is shrunk to just 9 pin.
What cable is used for RS232?
DB9 cable
Keep in mind that RS232 is simply a form of serial communications, or a way to transmit data. A standard DB9 cable is probably the most used cable for this application.
What is a 9 pin serial cable?
Many early PC designs used DB9 serial ports to communicate with other computers or hardware devices. This 9-pin layout become a de facto hardware standard that enabled device manufacturers to create products that worked on a wide range of computer platforms.
How many pins does an RS232 connector?
nine pins
An RS232 pinout 9 pin cable features nine pins: 2. Received Data – The data set receives the initial signal via the receive data line (RxD).
Is RS232 DB9?
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).
How many wires are needed for RS232?
3 signal
Wiring a Rs232 interface Most RS-232 devices will operate with only 3 signal wires: Transmit (TX), Receive (RX) and Ground (GND). In order for two RS-232 devices to communicate, you must connect the TX from one instrument to the RX of the second instrument, and vice versa. The Ground pins must be connected together.
Is RS-232 analog or digital?
RS232 Standards One of the advantages of the RS232 protocol is that it lends itself to transmission over telephone lines. The serial digital data can be converted by modem, placed onto a standard voice-grade telephone line, and converted back to serial digital data at the receiving end of the line by another modem.
What are the RS-232 connectors?
Connectors. RS-232 devices may be classified as Data Terminal Equipment (DTE) or Data Circuit-terminating Equipment (DCE); this defines at each device which wires will be sending and receiving each signal. According to the standard, male connectors have DTE pin functions, and female connectors have DCE pin functions.
What is a 9 pin cable used for?
What is DB9 Cable? A DB9 cable consists of a 9-pin connector and you can use it for connecting computer peripheries like keyboards and mice. The name of this connector has come from its trapezoidal shape which looks like the letter “D”.
What is the function of pin 3 in the 9 pin serial port?

| Pin | Signal | Description |
|---|---|---|
| 3 | TD | Serial data from host to mouse (only for power) |
| 2 | RD | Serial data from mouse to host |
| 7 | RTS(Request to Send) | Positive voltage to mouse |
| 8 | CTS(Clear to Send) |
Is RS-232 a protocol?
RS232 is a standard protocol used for serial communication, it is used for connecting computer and its peripheral devices to allow serial data exchange between them. As EIA defines, the RS232 is used for connecting Data Transmission Equipment (DTE) and Data Communication Equipment (DCE).
